Q:What is the relationship between the hardness and tensile strength of rubber pad?
The molecular weight increases, increasing the fan Edward force, the chain segment is not easy to slip, the equivalent of molecules formed between physical crosslinking points with the molecular weight increased, the tensile strength increased to a certain extent reached equilibrium; the microstructure of the molecule, such as the effect of CIS and trans type structure; crystallization and orientation.
Q:What is the cause of the bursting of rubber products and how should they be improved?
Improvement measures: 1.. Adjust the molding sulfuration temperature, adjust the temperature of the upper and lower plate. 2. adjust the exhaust distance and exhaust time. 3. in strict accordance with the mixing process standards or adjust the formula and mixing process, avoid the use of time is too long to place material (fast cooked). 4., in the explosive edge position plus running trough. 5. control the weight of a single adhesive.
Q:Why is rubber forest a green desert?
Long ago, the people have the knowledge of the use of wild rubber. Before Columbo came to the new world, no one outside the Americas knew that there was a species called rubber, and never thought that there would be a magical liquid out of the tree trunk that could change the progress of human civilization one day.
Q:The silica gel of the kettle is the white one that is waterproof and leaked out
Natural rubber (NR) is mainly composed of rubber hydrocarbons (polyisoprene), containing a small amount of protein, water, resin acids, sugars and inorganic salts. The utility model has the advantages of large elasticity, high extension strength, high tear resistance and electrical insulation, good abrasion resistance and drought resistance, good processability, easy adhesion to other materials, and superior performance in synthetic rubber in comprehensive performance. The disadvantage is that oxygen and ozone resistance is poor, easy aging, metamorphism, oil and solvent resistance is bad, resistance to acid and base corrosion is low; heat resistance is not high. Temperature range: about 60 DEG C 80. Make tires, rubber shoes, hose, tape, wire and cable insulation and sheath, and other general products. The utility model is especially suitable for making torsional vibration eliminator, engine shock absorber, machine support, rubber metal suspension element, diaphragm and molded product.
Q:What kinds of vulcanized rubber do you have?
According to the appearance of rubber: rubber can be divided into solid rubber (also known as dry rubber), emulsion rubber (referred to as latex), liquid rubber and powder rubber four categories.
Q:How to improve the hardness of rubber?
1. selection of high Mooney rubber (high molecular weight);2., increase the dosage of reinforcing agent, or choose the reinforcing agent with high structure and large specific surface area;3. reduce the amount of plasticizer, softener, or use viscosity high plasticizer;4. proper increase of gum content;5., improve the degree of cross-linking (increase the amount of vulcanizing agent, appropriately prolong the curing time, etc.);6., use stiffening resin, high styrene and other hardening agent;7. rubber and plastic combination;8. reduce plasticizing and prevent over refining;
Q:How can I make rubber products brighter?
Special release agent for rubber products, release agent.Mold release agent is an interface coating used on two surfaces that are easy to adhere to each other. It can make the surface of the material easy to break off, smooth and clean. Mold release agent is used in various molding processes, such as glass fiber reinforced plastics, metal die casting, polyurethane foam and elastomer, injection molding thermoplastic, vacuum foaming sheet and extrusion section. In molding, sometimes other plastics, such as plasticizers, leak to the interface, and then a surface remover is needed to remove it.
Q:What is the definition of mixed rubber?
Mixed rubber, also called synthetic rubber, is a synthetic, highly resilient polymer. Also known as synthetic elastomer, is one of the three major synthetic materials, its yield is only lower than synthetic resins (or plastics), synthetic fiber.
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:Explain why butyl rubber is more resistant to oxidation and aging than other elastomers, such as natural rubber
The macromolecular structure unit of natural rubber is isoprene, and the macromolecular chain is mainly composed of CIS -1, 4 polyisoprene. NR is the mechanical and processability comprehensive properties of all rubbers
