- Q: What solvent is used to clear the melted rubber layer?
- Natural rubber is made from latex, and a portion of the non - rubber contained in the latex is left in the solid rubber. In general natural rubber contains rubber hydrocarbon 92%-95%, but not rubber hydrocarbon accounts for 5%-8%. Because of the different processing methods, different habitats and even different seasons, the proportion of these ingredients may vary, but basically within the scope.Proteins can promote the vulcanization of rubber and retard aging. On the other hand, the protein has strong water absorption, can cause rubber moisture absorption, mildew, insulation degradation, protein and increase heat generation shortcomings.
- Q: What is the role of softening plasticizers in rubber? How are they classified?
- The plasticizer used in the production process should meet the following conditions: good plasticizing effect, low dosage, quick absorption, good compatibility with rubber, low volatility, no migration, cold resistance, water resistance, oil and solvent resistance, heat resistance, light resistance, good insulation, good flame resistance resistant bacteria, colorless, non-toxic, cheap and so on.But in fact, it is impossible to fully satisfy the above-mentioned conditions of plasticizers. Therefore, in actual use, more than two or more kinds of plasticizers mixed use, in order to make up for each other, where the amount of commonly known as the main plasticizer, and the other called auxiliary plasticizer.
- Q: Rubber soaked with hot water will not come out harmful substances?
- Chloroprene rubber is electrical insulation, cold resistant performance is poor, rubber is not stable in storage. Neoprene is widely used, such as the manufacture of transport belts and belts, wires and cables, and the manufacture of oil resistant hoses, gaskets, and chemical resistant equipment linings.
- Q: Process for producing rubber products
- In the production process of rubber products, the process of making various shapes and sizes is made by using a calender or an extruder, which is called forming. Forming methods are1. rolling formingThe utility model is suitable for making simple sheet and plate shaped articles. It is a method of pressing compound rubber into a certain shape and a certain size of film by calender. It is called calendering forming. Some rubber products, such as tires, adhesive tape, hose and other textile fiber materials, must be coated with a thin layer of glue on the fiber, also known as glue or glue, the process of gluing is generally completed on the calender. Fiber material needs drying and dipping drying before calendering. The purpose is to reduce moisture content of fiber material, avoid evaporation and foaming, and increase the temperature of fiber material, so as to ensure the quality of calendering process. Dipping is a necessary process before cementing. The purpose is to improve the bonding property of fiber and rubber.2. extrusion moldingFor more complex rubber products, such as tyres, tread, hose, and wire surface coating, shall be made by extrusion molding. It is a method of continuous molding with a certain plastic compound into the extruder's hopper, the extrusion of the screw under the internal screw, and through a variety of dies, also known as the templates. Before extrusion, the material must be preheated to make the material soft and easy to extrude so as to obtain a smooth and accurate rubber product.3. moldingIt can also be used to make some rubber products with complex shapes, such as leather bowl and sealing ring. The rubber material is placed in the mold and shaped by heating.
- Q: What about the Poisson's ratio and modulus of elasticity of three yuan ethylene propylene rubber (EPDM)?
- Three yuan ethylene propylene rubber is ethylene, propylene and non conjugated diene three yuan copolymer, began commercial production in 1963. The consumption of the whole world is 800 thousand tons every year. The most important feature of EPDM is its superior oxidation resistance, ozone resistance and corrosion resistance. Because three yuan ethylene propylene rubber belongs to polyolefin family, it has excellent curing property. Of all rubbers, EPDM has the lowest specific gravity. It absorbs large amounts of fillers and oils and has little effect on properties. Therefore, rubber compounds with low cost can be made.
- Q: Why is natural rubber a strategic material?
- Standard rubber: standard rubber is mainly divided into 5 glue, No. 10 glue and No. 20 glue. Glue No. 5 is the first grade glue. It is the best glue. Its impurity is 0.05%; No. 10 glue is two grade glue, its impurity is 0.10%, 20 glue is three glue, and its impurity is 0.20%. Glue uses different models are not the same: No. 5 commonly used to make rubber tyres; No. 10 and No. 20 rubber glue for making tire.Smoke film: the natural film pressure to the water were smoked after baking film by burning the coconut shell by smoke and heat. The purpose of fumigation is to make the film dry and inject anti oxidation and antiseptic cresol substances. Natural rubber is the primary form of smoke film.Concentrated adhesive: it can be used as bonding material.
- Q: How to clean rubber products?
- Rubber products are made of rubber raw materials and made from mixing rubber and mixed rubber as raw materials. When the rubber is mixed, the formula is designed according to the characteristics of the required rubber products, and the hardness of the products is determined. The product is made and molded by rubber flat vulcanizing machine. Finally, the product is processed by flying edge, and the surface of the product is treated smoothly without burrs.
- Q: Can the rubber surface be painted with paint?
- As long as waterproof, dustproof, isolated air is conducive to prolonging the service life of rubber. It can be applied with Vaseline, methyl silicone oil and so on.
- Q: I do rubber products, I would like to ask what metal accessories are rubber products, the specific name is what, good, then points
- High pressure rubber tube, natural rubber tube, Shandong rubber tube, high pressure rubber tube, low pressure rubber tube, Ding Qing rubber tube, high quality rubber tube;
- Q: How to improve the aging resistance of rubber?
- Whether it is rubber, rubber or rubber particles have a certain life, want to extend the service life of rubber and related products, we must first understand what factors affect the aging speed of rubber products, the four main factors affecting the aging of rubber particles for oxygen, ozone, heat and light.Oxygen oxidation by the rubber molecules of free radical chain reaction, molecular chain fracture or excessive crosslinking, cause the rubber properties changes.
