Q: What is the pressure on rubber products during vulcanization?: It can be seen that the vulcanization time can be shortened by increasing the sulfuration temperature. The process of high temperature vulcanization is injection vulcanization and electric heating flat vulcanization. Both of them can be cured at 160 DEG C or even higher. In recent years, the industry has also adopted the trend of high temperature vulcanization. In addition, the continuous vulcanization process using eutectic liquid as heating medium has also begun to use high temperature vulcanization. In the rubber injection molding process, because the rubber material has passed the preheating and plasticizing of the screw, higher vulcanization temperature (such as 175~183 DEG C) can be adopted, but the reversion or sulfuration of rubber is less affected. For example, for three yuan ethylene propylene rubber, when set 160 degrees for molding, the positive curing time is 60min, if it is changed to 200 degrees noteThe time of vulcanization is only 4min. With the use of general-purpose rubber to make small products, the vulcanization time can be l-2mm.

Q: How to enhance the performance of water resistant silicone rubber products: Steam can also reduce the performance of silicone rubber / silicone products, essentially the fracture of the backbone. The hydrolysis fracture reaction becomes apparent due to the increase of temperature and the presence of ionic reagents.

Q: How does the rubber part of the watch become yellow?: The rubber strap is yellow and rubbed with the weld polish. Remember, the ratio is 1 to 70.

Q: NR natural rubber manufacturers, who knows Guangdong here, there are manufacturers, a few hair connection is OK: 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 not good, the first corrosion resistance of acid and base 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: Properties and specific uses of various rubbers: Natural rubber is mainly derived from the Hevea tree. When the epidermis of this rubber tree is cut open, it will shed milky juice. It is called latex, and the latex will be natural rubber when it is condensed, washed, molded and dried.

Q: What are the ingredients in the tires?: Tires include rubber, polymers, sulfur, carbon black, and other chemicals. Each tire contains more than 150 components, so in the tire production process, from raw material processing to the tire baking to the end, the process is complicated and long.

Q: Can rubber products be injection molded and plastic injection functions?: Rubber products can be injection molding, plastic injection function.

Q: What about the smell of smoked rubber products?: The curing agent and accelerator taste, rubber itself is tasteless, sulfur curing agent debris less is better, if no sulfur, with peroxide. Oil will also produce a flavor, rubber Odor Remover can be removed, in fact, that is, some spices, oh!Now there is a special rubber deodorant in the market, you may as well try.Can buy some activated carbon in the box, the cost is not high, but also long lasting odor.

Q: What kind of rubber is suitable for waterproof aprons?: Rubber is a kind of macromolecule elastomer that can deform greatly under external force and can quickly recover its original shape when the external force is lifted.Rubber is divided into: natural rubber, synthetic rubberAmong them, synthetic rubber is divided into: general rubber, special rubber.General rubber:Styrene butadiene rubber, butadiene rubber, butyl rubber, EPDM rubber, chloroprene rubberSpecial rubber:Nitrile rubber, chloroprene rubber, chloroprene rubber, fluorine rubber, epichlorohydrin rubber, silicone rubber, polyurethane rubber, polysulfide rubber, acrylic rubber

Q: How to solve the spray of rubber products?: Rubber spray, including rubber surface spray and surface spray. Spray cream is a liquid or solid compounding agent made from rubberThe phenomenon of internal migration to the rubber surface is the precipitation of the rubber compounding agent.
