Basic steps of rubber mixing

      If it is an indispensable part to make rubber raw rubber into a variety of mature rubber products, what are the links of rubber mixing? The following is a professional rubber manufacturer to introduce you to the four major steps of rubber mixing.

      First, the choice of mixing materials, in the process of mixing, due to the low cohesion between the rubber molecules, the high-strength and high-temperature silica filler becomes the most important compounding agent for rubber. When other compounding agents are used, Need to consider the requirements of high temperature resistance, that is, under the application conditions of rubber, they should not be volatilized, decomposed, charred or discolored, etc. In order to maintain the heat resistance of raw rubber, the silicon bond is reduced by acid and alkali, and the mixture is broken and mixed. To prevent the introduction of foreign acids and alkalis, it is necessary to remove the acidic substances generated by the decomposition of the peroxide vulcanizing agent in time.
      Second, in the mixing of the raw rubber and other ingredients into the vacuum kneader, the temperature is not high at the beginning, during the stirring process, by the temperature of the temperature slowly reached 155-160 degrees, It will take another half hour.

     Third, put the cooked glue in the open mill to smooth and roll into a roll. Just take care not to get dirty. The number of rolls only needs 2-3 rings.
     Fourth, after smoothing, it should be cooled. The time is about 3-4 hours. Then, through the match net, the glue is filtered again. The purpose is to filter out some solid materials inside the glue.
   

The difference between PE/PVC/POF heat shrinkable film

Heat shrinkable film is used in the sale and transportation of various products, and its main function is to stabilize, cover and protect the product. The shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. There are many types of heat shrinkable film, which are used in various fields. The most important three types are PE/PVC/POF heat shrinkable film. What are the differences between the three?

PE heat shrink film PE polyethylene, which is a transparent thermoplastic. PE is commonly used in three categories, namely: LDPE HDPE LLDPE The three polyethylene monomers are the same, except that the process conditions used to synthesize these polyethylenes are different, so three different polyethylenes are produced. Variety, the performance of the three materials has a big difference. PE film is a very tough material, not easy to smash with ordinary plastic pulverizer. Because the PE film is soft and tough, it is not easy to shred, not to mention the high temperature of the tool at high speed, which will cause the LDPE to melt and adhere to the blade. The granulation of PE can be directly placed into the feeding port of the extruder, and the PE film is dragged into the barrel by the shearing force of the screw to heat, melt and extrude the granule. The first grade material recycled by PE is still blown film, used for non-food and pharmaceutical packaging, and is also widely used in the production of oxford leather and tarpaulin, with a bright future. PE heat shrinkable film is widely used in the whole collection packaging of wine, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, strong impact resistance, tear resistance, not easy to be damaged, not afraid. The tide and shrinkage rate are large.

PVC heat shrinkable film PVC polyvinyl chloride, with added ingredients to enhance its heat resistance, toughness, and ductility. The uppermost layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the lowermost layer is a back-coated adhesive. It is a well-loved, popular and widely used synthetic material in the world today. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material. Due to the unique properties of PVC (rain, fire, antistatic, easy to form) and PVC low input and high output, it is widely used in building materials industry and packaging industry. Therefore, PVC film has high transparency, good gloss and shrinkage. High rate and other characteristics.

POF heat shrinkable film POF is the meaning of heat shrinkable film. POF is a multi-layer co-extruded polyolefin heat shrinkable film. It uses linear low density polyethylene as the intermediate layer (LLDPE) and copolypropylene (pp) as the inner and outer layers. It is plasticized and extruded by three extruders, and then processed by special processes such as die forming and bubble inflation. POF is a heat shrinkable film mainly used for packaging regular and irregular shapes. Due to its non-toxic environmental protection, high transparency, high shrinkage, good heat sealing performance, high gloss, toughness, tear resistance, Uniform heat shrinkage and suitable for automatic high-speed packaging, it is a replacement of traditional PVC heat shrinkable film, widely used in automotive supplies, plastic products, stationery, books, electronics, circuit boards, MP3, VCD, crafts, photo frames, etc. Products, toys, pesticides, daily necessities, food, cosmetics, canned drinks, dairy products, medicine, cassettes and videotapes.

7 questions to pay attention to using hydraulic hose

     As a common type of hose, hydraulic hoses are used in many places, but how do you know how to use rubber hoses correctly? The following is a professional hydraulic tube manufacturer to explain the common problems of using hydraulic hoses. .

     1. The hydraulic tube expands and contracts with its internal pressure. Cut the hydraulic tube to a length slightly longer than you need.
     2. Please use it under the condition of hydraulic bending radius, otherwise it will cause the rubber tube to break and reduce the pressure resistance.
     3. The hydraulic pipe contains metal parts. Do not use it when the end is bent.
     4. Do not directly touch the hydraulic pipe to the open flame. Do not press the hydraulic pipe with the vehicle.

     5. Always use hydraulic hoses within the recommended temperature and pressure ranges.
     6. When applying pressure, please slowly switch any valve to avoid impact pressure.

     7. When using powder or granules, it may cause wear and tear according to the conditions. Please enlarge the bending radius of the hydraulic pipe as much as possible.

How to eliminate the flaws on the pp jacket

First, the phenomenon of sputum

 

(1) The ruthenium produced by the resin during the plasticization process has small crystal spots and small particles on the surface of the plastic layer, which are distributed around the surface of the plastic layer.

 

(2) The crucible generated by scorching has scorch on the surface of the plastic layer, which is particularly reflected on the surface of the glue joint.

 

(3) Impurities have impurities on the surface of the plastic, and there are impurities in the sliced ​​crucible.

 

(4) Plastic enamel produced by poor plasticization. After slicing, it was found that the inside of the mash was cooked.

 

Second, the cause of embarrassment

(1) Since the temperature control is low, the plastic has not been plasticized and is extruded from the machine head.

 

(2) The quality of the plastic is poor, and there are resins that are difficult to plasticize. These are extruded without being completely plasticized.

 

(3) Some impurities are added to the hopper during feeding, causing impurities.

 

(4) The temperature control is super high, causing scorch, which causes burnt coke.

 

(5) There is no compression on the molded cover, and the aging deteriorates after the glue is applied, and the burnt sputum appears.

 

Third, the method of eliminating cockroaches

 

(1) The flaw caused by the plastic itself should be appropriately increased.

 

(2) Strictly check whether there is any foreign matter in the plastic feeding. Do not put other impurities into the hopper during feeding. If the impurities are found, clean the machine head immediately and run the glue in the screw.

 

(3) If the temperature is too high, the temperature should be appropriately lowered immediately. If the effect is not good, the head and the screw should be cleaned immediately to eliminate the burnt material.

 

(4) In the case of resin defects and poor plasticization, it is necessary to increase the temperature or reduce the speed of the screw and traction.

Drilling hose introduction

  The full name of the drilling hose is called "Rolling Drilling and Shock Absorbing Rubber Hose". It can also be called "Drilling Equipment Hose". As a professional drilling hose manufacturer, let's introduce its application range and structure.
 

         
         Drilling hoses can be used in drilling, cementing, workover and petroleum geological exploration, small drilling rigs and water mining. Drilling hose is a flexible joint in mud manifold, cementing manifold, throttling and killing manifold, etc. It is commonly used to transport water, oil-based mud, cement slurry, well washing fluid and normal temperature water under high pressure. . The drilling hose can work normally between -30 and 82 °C.

 

 

        The structure of the drilling hose is composed of an inner rubber layer, an inner rubber protective layer, a middle rubber layer, a steel wire wound reinforcing layer and an outer rubber layer. The drilling hose is made of nitrile rubber which is resistant to oil, wear and acid and has good acid and alkali resistance. The tube reinforcement layer usually adopts 2 to 8 layers of strong steel wire winding structure, and the steel wires are bonded together by film to form a firm whole. Drilling hoses are usually made of neoprene which is resistant to oil, abrasion and weathering. It can be adjusted according to the specific needs of customers.

       
         The above is the main knowledge of the drilling hose introduced to everyone, I hope to help everyone.

How to check the quality of rubber oil tubing

Rubber oil hose is a hose that is often used in daily life. The safety check of rubber hose is very important. Once it has oil leakage, cracking and other faults, it will directly affect the safety of the whole machine operation. How to verify?

Rubber tubing refers to a hose composed of rubber and steel wire that is specially used to transport oil. The quality of rubber tubing can be easily tested by the following three tests.
1. Rubber tube hydraulic test: This is mainly to test whether the rubber tube and the assembly are leaking, deformed and destroyed under the verification pressure for 30s-60s. There is also a pressure deformation test, which is held for 1 minute under the specified pressure, and measures the length and outer diameter of the hose and the torsion angle and bending.
2. Rubber tube burst pressure test: It refers to the pressure at which the hose is blasted at a specified boosting speed.

 3, rubber tube leakage test: This is stored under the static pressure of 70% of the small burst pressure for 5min, repeated once, check for leakage or damage. The above is one of its inspection standards. In order to get a rubber tube of better quality, the rubber tube is indispensable for inspection standards.

The cause of cracks in the hydraulic pipe

If the hydraulic hose is of poor quality, it is likely that some problems will occur during use. Common faults are oil leakage, surface blistering and cracks on the surface. As a professional hydraulic pipe manufacturer, let us introduce the reasons for the cracks in hydraulic hoses and preventive measures.

The rupture of the hydraulic hose may be caused by a problem with the surface of the outer hose or by a defect in the inner rubber layer. Let me introduce you in detail below.

The problem of the inner rubber layer often occurs in the steel wire reinforcement layer, which is the skeleton of the hose, usually composed of steel wires. High-pressure and ultra-high pressure hydraulic pipes are mostly made of multi-layer steel wire. Low-pressure hydraulic pipes are made of cotton and linen, and are usually used in low-pressure oil return pipes. If the quality of the steel wire reinforced layer is not good, it is easy to suffer from aging and the pressure capacity is greatly reduced. In this case, the hydraulic pipe can easily exceed the working pressure range to cause cracks on the surface. Therefore, it is necessary to select a highly qualified hydraulic pipe product.

The problem of the outer surface of the rubber is often due to the environmental impact. Many hydraulic pipes work in harsh environments. If the resistance is not good, cracks and other problems are likely to occur. For example, in a relatively cold winter environment, the outer surface of the inferior rubber hose is prone to cracks or even distortion, and the work performance is seriously degraded or even poses a great safety hazard.

Therefore, the main reason for the crack on the surface of the rubber tube is that the quality of the product is not high enough, so everyone should choose a high quality product when purchasing the hydraulic tube.

Several factors that cause the rubber tube to age

Rubber tubes will gradually appear aging during daily use, so what are the factors that cause the rubber tube to age? As a professional rubber manufacturer
(1) Oxygen: Oxygen undergoes a radical chain-locking reaction with rubber molecules in a rubber tube, and the molecular chain is broken or excessively crosslinked, causing a change in rubber properties. Oxidation is one of the important reasons for rubber aging.

(2) Ozone: The chemical activity of ozone is much higher than that of oxygen, and it is destructive. It also breaks the molecular chain, but the effect of ozone on rubber varies with the deformation of rubber. When it is used as a rubber for deformation (mainly unsaturated rubber), a crack perpendicular to the direction of stress action occurs, that is, “ozone cracking”; when it acts on a deformed rubber, only an oxide film is formed on the surface without cracking.

(3) Heat: Increasing the temperature may cause thermal cracking or thermal crosslinking of the rubber. But the basic role of heat is activation. Increasing the rate of oxygen diffusion and activating the oxidation reaction to accelerate the oxidation reaction rate of the rubber is a ubiquitous phenomenon of aging – thermal aging.

(4) Light: The shorter the light wave, the greater the energy. What is damaging to rubber is the higher energy of ultraviolet light. In addition to ultraviolet rays directly causing the breakage and cross-linking of rubber molecular chains, rubber generates free radicals by absorbing light energy, which initiates and accelerates the oxidation chain reaction process. Ultraviolet light plays a role in heating. Another feature of light action (unlike heat) is that it mainly occurs on the surface of the oak. For samples with high gel content, there will be reticular cracks on both sides, the so-called “outer layer cracking”.

(5) Mechanical stress: Under the repeated action of mechanical stress, the rubber tube molecular chain will be broken to form a free radical, which will initiate the oxidative chain reaction and form a force chemical process. Mechanically broken molecular chains and mechanically activated oxidation processes. Which one can prevail depends on the conditions in which it is located. In addition, it is easy to cause ozone cracking under stress.
(6) Moisture: The effect of moisture has two aspects: when the rubber tube is exposed to moisture or immersed in water, it is easily destroyed. This is because the water-soluble substance and the water-clearing group in the rubber are extracted by water. Caused by hydrolysis or absorption. Especially in the alternating action of water immersion and atmospheric exposure, the rubber damage will be accelerated. However, under certain circumstances, moisture does not have a destructive effect on rubber, and even has the effect of delaying aging.nergy radiation, electricity and biology.

The above are the main reasons why I have summarized the rubber tube aging. I hope that everyone can start from these aspects to avoid the aging of the rubber tube.

Several simple methods for silicone tube testing

Silicone tubes are increasingly popular with consumers because of their unique advantages. However, in recent years, the quality of hoses in the silicone tube market has been uneven, in order to help everyone buy quality products. Today, Runte Rubber and Plastics teaches you how to choose a quality silicone tube in a few simple steps.

The first step: the tensile test was carried out by hand pulling out the silicone tube without obvious deformation or elongation, and there was no crack after bending back and forth three times. The silicone tube skin does not have any wrinkles; such a silicone tube is of good quality.

The second step: the flame retardancy test ignites the silicone tube under the open flame, and the natural extinguishment after 5S is good in quality and vice versa.

The third step: bonding strength test The silicone tube to be tested is repeatedly folded 3-5 times at 180 degrees, and then subjected to a withstand voltage test; the degree of deformation of the silicone tube is observed.

Step 4: High temperature resistance test After testing the silicone tube through a tunnel furnace (120 ° C, 45 minutes) for 1-2 m, there should be no appearance defects such as yellow bubbles on the surface, and then the high temperature silicone tube is subjected to a withstand voltage test. Observe if the pressure requirements are met.

Step 5: High-voltage resistance test: The silicone tube to be tested is sampled (the tensile test after the high-temperature welding test), and then the corresponding conductor (copper rod or iron rod) is taken out through the silicone tube to take out the pressure tester. One end of the pressure bar is in contact with the conductor, and the other end is moved back and forth over the silicone tube through which the conductor passes. When the silicone tube ruptures, the pressure gauge sounds an alarm, which is a substandard product, and vice versa.

Why do rubber products turn white?

In life, many people have certainly seen the phenomenon of whitening after using rubber products for a period of time. For example, in the case of high humidity, the paint tends to be white. So why are rubber products white? How to avoid whitening rubber products?
The reason for the whitening of rubber – blooming

Blowing refers to the phenomenon that a liquid or solid compounding agent is moved from the inside of the rubber to the appearance of the rubber to cause whitening of the rubber product. The way of rubber frosting is summarized and divided into three types. That is, dusting, spraying wax, and spraying oil (also called oozing).
Powder spraying is a powder compounding agent such as a vulcanizing agent, a promoter, an active agent, an antioxidant, a filler, and the like, which are separated from the rubber surface to form a layer of powder.
The wax spray is a wax such as white wax or glaze wax which is separated from the rubber surface to form a wax film.
The fuel injection is a liquid compounding agent such as a softener, a tackifier, a lubricant, a plasticizer, etc., which is separated from the rubber surface to form a layer of oil. The way rubber is sprayed on the surface is sometimes presented in one way, sometimes in two or three ways.

How to avoid rubber products bloom

(1) Formulation planning is reasonable to avoid being too full
(2) Technical operation to pay attention to avoid errors
(3) Rubber raw materials and finished products should be taken care of during storage to avoid aging and moisture.

BOP Hose

BOP Hose Introduction

Why do you need a bop tube?

   In order to prevent blowout, blowout is a very dangerous thing. When drilling a gas-bearing or oil-bearing layer, huge oil and gas pressure can spray the drill pipe mud, destroy the drilling platform, pollute the environment and threaten the safety of the staff. Even the surrounding residents are safe, and the toxic gas (hydrogen sulfide) is ejected, which has a great impact.

   How does the bop tube work?

    The drill pipe is also used in the well while it is still in the well, and the other pipe is used when there is no drill pipe. They are all rubber-wrapped gates that rely on hydraulic push to close and open. The ring is also rubber, which relies on hydraulic power to push the extrusion to achieve the purpose of sealing. There are also control equipment for bop: gas tanks, pumps, hydraulic equipment, control switches, piping, valves, etc.

Bop tube response time?

The corresponding time of the ring bop is 60 seconds, and the corresponding time of the shutter type bop is 30 seconds.

 When is the bop tube closed?

    Depending on the device that monitors the pressure at the wellhead, it is determined whether it needs to be closed. If the pressure continues to increase after closing and the shearing pipe cannot be sealed, the person on the drilling platform should be informed that it has started to escape. There is a slide on the land's drill floor that is used for emergency escape.

What should I do after the BOP tube is closed?

     After the bop hose is closed, the chock and kill manifold, MGS-mud gas separator, are used.
