Q:How do rubber undergo vulcanization?
Heat vulcanization can be divided into three methods: direct vulcanization, indirect vulcanization and mixed gas vulcanization. Direct vulcanization; vulcanizing in hot water or steam medium. Indirect vulcanization, vulcanization in hot air. Third, gas vulcanization, first vulcanization with air, and then direct steam vulcanization.
Q:How are rubber wires processed?
In the production of rubber products, vulcanization is the last process.Vulcanization is a crosslinking process in which rubber molecules change from linear structure to network structure under certain conditions. Curing methods are cold vulcanization, room temperature vulcanization and heat vulcanizing three kinds. Most rubber products are vulcanized by heat. Hot vulcanizing equipment, vulcanizing pot, flat vulcanizing machine, etc.. Rubber wires and cables are vulcanized by continuous hot air.
Q:How long does the rubber last?
In addition, aging has ozone aging, weather aging, heat aging and so on. Ding Qing rubber is not resistant to ozone, the time is not long, it will appear aging.
Q:How can I make rubber products brighter?
The release agent shall have greater tensile strength so that it is not easy to be polished when it is in contact with the molding resin. This is especially true when there are frosted mineral fillers or glass fiber reinforcements in the resins. The release agent shall be chemically resistant so as not to be dissolved in contact with the chemical constituents of different resins (especially styrene and amines). Release agent should also have heat and stress properties, not easy to decompose or wear; release agent should be bonded to the mold, and not transferred to the processed parts, so as not to interfere with painting or other two processing operations.
Q:Why do rubber products become so long that they seem to melt and become sticky on the surface?
The main reason for the melting of rubber products is the long usage time or the long time of placing rubber;"Sticky" is because the rubber in the presence of oxygen oxidation reaction, the result is hydroxyl, carboxyl and other polar groups increased. These polar groups are the cause of the sticking of things. In layman's terms, it's equivalent to becoming a self-adhesive.
Q:What is the harm of rubber to the human body?
In use, some contact with the human body rubber requirements are very high, from the choice of gum species (usually silicone rubber and PU), to the use of mixing agents, have strict requirements.
Q:What are the forming methods of rubber products?
In rubber products, the main molding technologies are molding, forming, transfer, forming, wrapping, molding and injection molding.
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:What gum does rubber and metal stick together?
JL-480 black rubber instant glue: medium viscosity, high strength, etc. used for inert surface, bonding, porous, acid, vibration and heat resistance, rubber, metal, plastic bonding. The utility model can be used for large gaps and more dispensing. High viscosity, impact resistance. The curing is slow, the curing has toughness, and the adhesive force is strong. After bonding, the adhesive surface can reach two and the adhesive surface dissolves as a whole. It is a shock resistant instant adhesive, which has better seismic and stripping strength than other series. Widely used, bonding rubber, plastic, and metal as adhesive for impact resistance. It is more flexible than conventional adhesive.
Q:What is the difference between rubber expansion joint and rubber joint?
The expansion joint is also called expansion device, expansion joint and compensator. It is divided into several types, such as ripple compensator, sleeve compensator, rotary compensator and square natural compensator, and also has intubation type expansion joint. Among them, the corrugated compensator is more commonly used, mainly to ensure the safe operation of the pipeline, and has the following functions: 1.. Compensating the axial, transverse and angular thermal deformation of the absorption pipeline. 2. vibration absorption equipment to reduce the impact of equipment vibration on the pipeline. The deformation of the pipeline 3., absorption of seismic subsidence.
