Q:What is the lowest cost material for the synthesis of rubber?
There are many kinds of synthetic rubber. Many kinds of materials are used in synthesis, which material is lower or can not be measured
Q:Are natural latex rubber products?
Non rubber components contain proteins, lipids, sugars, and inorganic compounds, some of which are compounded with rubber particles, partially dissolved in whey or form non rubber particles. Natural rubber is a kind of polyisoprene as the main component of natural polymer, the molecular formula is (C5H8) n, 91%~94% in its composition is rubber hydrocarbon (polyisoprene), the protein, fatty acid, carbohydrate, ash and other non rubber substances. Natural rubber is the most widely used universal rubber.
Q:How to improve the aging resistance of rubber?
Whether it is rubber, rubber or rubber particles have a certain life, want to extend the service life of rubber and related products, we must first understand what factors affect the aging speed of rubber products, the four main factors affecting the aging of rubber particles for oxygen, ozone, heat and light.Oxygen oxidation by the rubber molecules of free radical chain reaction, molecular chain fracture or excessive crosslinking, cause the rubber properties changes.
Q:Is it necessary to use rubber products for steel structure buildings?
There must be a rubber cushion for the gear of the crane beam, and there is also a rubber cushion between the crane track and the crane beam. Of course, not all deformation joints are rubber, depending on how to choose the design node.
Q:What are the hazards of waste rubber and how can they be used for regeneration?
In addition to piling up waste rubber products as fuel burning, scientists have been studying more effective waste rubber regeneration technology since 1910. Reclaimed rubber refers to the physical and chemical processes such as comminution, heating and mechanical treatment of waste vulcanized rubber, which can change from elastic state to vulcanized rubber with plasticity and viscosity. The essence of the regeneration process is the comprehensive effect in heat, oxygen, mechanical function and recycling agent of chemical and physical functions, make the network vulcanizate degradation, the fracture position of both crosslinks, also have large molecular cross-linking bond between. Rubber regeneration methods can be broadly divided into two categories: physical regeneration and chemical regeneration.
Q:How to remove the peculiar smell of rubber products?
The general method is to add some flavor spices used to degrade or reduce all kinds of rubber produced in the processing or use process in acids, alkoxy compound such as smell, method is effective, but not fundamentally solve the problem.
Q:Silicone is silicone rubber? Extracted from there?
Generally speaking, silica gel can be divided into two categories: organic silica gel and inorganic silica gel according to their properties and components. According to its composition, it is divided into extruded silica gel and molded silica gel.
Q:Advantages and disadvantages of rubber products
Styrene butadiene rubber SBR(Styrene Butadiene Copolymer) and butadiene styrene copolymers, compared with natural rubber of uniform quality, less foreign body, has better wear resistance and aging resistance, but the mechanical strength is weak, can be combined with natural rubber mixing. Non - oily material advantages: low cost, good water resistance, hardness below 70 with good elasticity, high hardness with poor shortcomings: compression, does not recommend the use of ozone, acid, oil, oil and fat ester and most hydrocarbons. Widely used in tire industry, shoes, cloth and conveyor belt industry etc..
Q:What plastic rubber will not be subjected to oil (such as transformer oil) by quality (e.g., aging, dissolution)?
The most essential difference between plastics and rubber is plastic deformation when plastic deformation occurs, while rubber is an elastic deformation. In other words, it's not easy to restore the original state after plastic deformation, and rubber is relatively easy. Plastic elasticity is very small, usually less than 100, while rubber can reach 1000 or more. Most of the molding process of plastics is finished
Q:What is food grade natural rubber?
Standard rubber, natural rubber latex concentrate only and solid and liquid substances is concentrated latex by high-speed centrifuge after processing, required special barrel plus fresh, dry rubber content is 60%; the standard is a standard solid rubber rubber good solidification, machining, drying, packaging, which according to the impurity content to several levels and it has international standards, countries also have the corresponding standard.
