Q:How much is the recipe for Buddha's rubber?
The structure of natural rubber is a polymer of isoprene, and later appeared in many new varieties of synthetic rubber, mainly such as polybutadiene rubber, chloroprene rubber, styrene butadiene rubber and so on. The yield of synthetic rubber has greatly exceeded that of natural rubber, of which the largest yield is styrene butadiene rubber.
Q:What are the disadvantages of a rubber roof?
Housing rubber roof area must be greater than the housing area, mainly for water and rubber, heat up, cold weather.
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
Q:Why do rubber products Blister?
A lot of reasons, but the main factors are: 1) there are 2 water) mixed rubber Mooney viscosity high fluidity of the compound 3) poor curing pressure lowFrom what you say without adding mold agent foaming phenomenon is more obvious in terms of liquidity, the reason may not glue a problem.
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: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 do rubber undergo vulcanization?
Rubber vulcanization is a chemical reaction process, before vulcanization rubber is present in a linear molecular form, is the linear sulfide molecules through some other substances (such as sulfur and peroxide) connected together to form a three-dimensional network structure. Sulfur must not be used with sulfur material, as long as the rubber linear molecules can be linked together to form a body shape on the lineEach rubber formulation has an optimum curing temperature, which increases the speed of vulcanization within a certain range, but the performance of the product decreases
Q:What is the definition of mixed rubber?
AdvantageThe main purpose of the industrial synthesis of rubber material is cost saving, improving the properties of rubber products, because the natural rubber products price is more expensive, in order to reduce the cost of enterprises have invested a lot of synthetic rubber materials with low cost.Synthetic rubber material also has excellent heat resistance, cold resistance, corrosion resistance, and little affected by environmental factors, synthetic rubber materials and suitable for 60 to 250 degrees below zero normal use.
Q:How can rubber products be softened?
Rubber softener for fluid or semi fluid, dangerous goods, should be stored in the rain (the most important) ventilation dry place shading.A package (drums, plastic barrels, plastic bags), according to the needs of the customer.
Q:Can rubber products be injection molded and plastic injection functions?
Injection molding is a method of producing shapes in industrial products. Products are typically molded by rubber injection and plastic injection. Injection molding can also be divided into injection molding. Die casting method. Injection molding machine (referred to as the injection molding machine or injection molding machine) is plastics molding equipment of thermoplastic or thermosetting material using plastic mold made of various shapes, injection molding by injection molding machine and mold.
