FAQ
- What about rubber molding, foaming and layering?
- Foaming1 vulcanization is not sufficient, the temperature is too low or time is too short, so that the volatile compounds produced during curing have not been cleaned out;2, under the pressure of vulcanization, the trapped gas and sulfur volatile matter can not be discharged in time3, there is air or moisture in the glue;4, curing temperature is too high, the surface of the gum material premature vulcanization, hindered the glue material in the steam, air free precipitation5 vulcanization speed of material is too fast
- What are the uses of rubber oil?
- The effect of rubber regeneration: thick pine tar smoke containing regeneration agent of other small molecules, which can penetrate into the intermediate node containing uniform molecular sulfur rubber, the swelling, reticular structure relaxation, increased permeability and oxygen distance between molecular chains, also can be used as acceptor free the base, inhibiting gelation effect, also helps to accelerate the diffusion of the activator rubber matrix regeneration process, and can improve the regeneration of plastic viscosity and plasticity, and less pollution, good processing performance.
- What is rubber material?
- The word "rubber" comes from the Indian language "cau-uchu", meaning "weeping tree"". Natural rubber is flowing out from the Hevea latex when tapping after solidification and drying process. In 1770, British chemist J. Priestley discovered that rubber could be used to erase pencil writing. The material used at that time was called rubber, which has been used so far
- What is the definition of mixed rubber?
- Chemical property：Synthetic rubber is composed of different monomers under the action of the initiator, the polymerization of polymers of variety, monomer, styrene, butadiene acrylonitrile, isobutylene, chloroprene etc.. There are four kinds of polymerization process: emulsion polymerization, solution polymerization, suspension polymerization and bulk polymerization.
- 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.
- PVC conveyor belts and rubber belts differ from each other in their respective advantages
- Rubber belts are widely used in conveying equipment, but do you know that proper vulcanization of rubber can maintain high elasticity of rubber and make rubber of a certain strength?. At the same time, in order to increase product hardness, strength, wear resistance and tear resistance, while adding inert filler in the process (such as Zinc Oxide, clay, chalk and barite etc.) and reinforcing filler (such as carbon black), which helps to improve the quality of the conveyor belt.
- How can rubber be made into rubber when it is made?
- Rubber made of rubber products, to be mixed, vulcanized, trimming and many other processes to make rubber products, is a complex processing plant produced.
- Can PVC blend with rubber?
- PVC can be well compatible with NBR and difficult to use with other glue.
