- Q: How do soft silicone rubber print?
- Its role is to fill the gap between the heating power device and heat sink, or add in the heating device for cooling and surrounding objects, to achieve thermal temperature effect.
- Q: What does the rubber tire do to people?
- Rubber is an elastic polymer. Rubber can be obtained from the plant sap, can also be man-made, both have many applications and products, such as tires, washers, etc., has become an important economic crop. The cultivation of rubber is mainly concentrated in Southeast Asia, such as Thailand, Malaysia and Indonesia.
- 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: What are the causes of cracks in vulcanized rubber products?
- 1. Add some oil, 2. And reduce accelerator or vulcanizing agent 3., reduce the sulfidation temperature 4. After complete cooling
- Q: What is the specific gravity of natural rubber?
- Natural rubber is composed of rubber, hydrocarbon, water, resin, protein, sugar and inorganic salts, and its specific gravity is 0.90~0.93. The natural rubber without impurities is transparent and yellowish, with good viscosity and dielectric properties, and its tensile properties are generally higher than those of synthetic rubber. Soluble in benzene, solvent naphtha, carbon disulfide, carbon tetrachloride, chloroform, turpentine, etc., but not soluble in ethanol and acetone. With halogen, oxygen, ozone, peroxide, sulfur and so on. Widely used in the manufacture of rubber products, such as tires, rubber shoes, hose, tape, wire and cable insulation materials.
- 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 kind of rubber products are expensive?
- The size and size of rubber products determine the amount of glue used, which is a matter of cost;
- Q: How to identify the tire rubber is raw or cooked
- Rubber molding, after pressing, the elastic body is within the cohesion can not be eliminated, the molding die, often have a very unstable contraction (rubber shrinkage due to rubber vary), required after a period of time, and can be stable. Therefore, when a rubber product design at the beginning, regardless of formula or mold, it is necessary to carefully calculate the coordination, if not, it is easy to produce product size instability, resulting in lower quality products.
- Q: How do you remove the rubber on your new slippers?
- Bamboo charcoal (carbon fired bamboo) can purify the air and remove odors. I think the rubber should also be effective for slippers!
- Q: How to improve the aging resistance of rubber?
- The shorter the light wave, the greater the energy, the greater the damage to the rubber. Ultraviolet not only directly caused the breakage and crosslinking rubber, rubber surface is also resillage guttacontent especially high rubber is more obvious this is the light splitting outer rubber particles (black rubber particles and colored rubber particles).
