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 difference between a thermoforming machine and an injection molding machine in a rubber plant?
Hot pressing machine needs a forming template to process it, so there are many processes.If you shoot it, you can finish the product directly
Q:How to maintain and store the rubber material?
Rubber itself is a shelf-life, you can ask the supplier to warranty, above all, as fillers, such as calcium carbonate, carbon black, long time no problem, also have a shelf life of antioxidant promoter, especially individual species. When storing, pay attention to fire prevention, moisture-proof, away from the high temperature, avoid direct sunlight, of course, the general "first in first out" is a must follow the truth.
Q:How should the rubber products be dirty?
First coated with vinegar on the top, after dry, and then wipe paper, so clean
Q:Is there any poison in the processing and testing of rubber products? What about the salary?
With some raw materials are generally low in rubber products, such as sulfur, amine antioxidant, lead salt, nickel salt what.In addition, when processing or testing, if there is temperature, pay attention to good protection.As far as salaries are concerned, generally 2k-3k, of course, there is a difference between local manufacturers.
Q:How can I make rubber products brighter?
Consider cleaning with an alkaline solution. Regular soap is fine.If you did not meet the requirements, can go to the market to buy some special cleaning agent.
Q:What kind of product is suitable for rubber trimmer? Where's the rubber trimmer?
Rubber products, silica gel products, special rubber products only need to have the rubber parts of the dismantling groove, and the diameter of the rubber inside the 100MM can be used as trimming machine.
Q:How can there be a crack in the rubber ring?
Problems in production:1) formulation design, oil or resin less material or caused by excessive or high temperature, poor liquidity and other reasons!2) when manufacturing, the product appears the hole which the exhaust is not good3) the raw material is too thick during production, and cracks are also caused.
Q:Which is better waterproof performance, neoprene or silica gel?
High temperature silicone rubber is mainly used for making all kinds of silicone rubber products, while room temperature silicone rubber is mainly used as adhesives, potting materials or dies. The maximum amount of heat curing type, heat curing type and methyl silicone rubber (MQ), methyl vinyl silicone rubber (VMQ, dosage and product grades at most), methyl vinyl silicone rubber (PVMQ low temperature resistance and radiation resistance), there are other eyes of silicone rubber, fluorine rubber and so on.
Q:Half finished rubber film surface white is going on
Because inside the rubber compounding agent reachsupersaturation, rubber compounding agent near surface precipitates first, then from the inner to the surface migration of precipitation when complexing agent in the rubber to reduce its saturated state, precipitation process ended. Causes the complexing agent to achieve the supersaturation state, causes the rubber spraying frost the main reason to have: the rubber formula design is improper, the craft operation is not proper, the raw material quality fluctuates, the storage condition is poor, the product owes sulfur, the product aging and so on.
