Q:How can rubber be made into rubber when it is made?
Just cut off the rubber is not available, belongs to the first rubber, according to the products and the use of working conditions to set the formula, made of mixed rubber, vulcanized on the vulcanization machine with mold has been good, curing after trimming, testing, packaging. The required rubber products will be ready.The process flow of the production process is:Raw material preparation, plasticization, blending, molding, vulcanizing, cleaning and testing
Q:How to distinguish between silicone hose and rubber tube by appearance?
Smell, silicone no flavor, rubber flavor, silicone general flexibility better, rubber mechanical better
Q:Why is natural rubber a strategic material?
Rubber is an important strategic material, in the national defence application is very extensive, for example, a tank with more than 800 kg of general rubber; thirty thousand ton warship with sixty-eight tons of rubber, military equipment, air force facilities, almost all defense engineering rubber footprint. The use of rubber made ship, tent, warehouse and protective equipment, clothing etc. there are many varieties of bath water. As for the anti - tip technology needs high temperature, low temperature, oil resistance, high vacuum resistance and other special properties of the rubber, the constitution of 0 products is indispensable. With the development of national defense modernization, rubber, which is capable of resisting the temperature range of minus 100-400 DEG C and capable of resisting various acids, bases and oxidants with special properties, is being developed and manufactured.
Q:Is sandal rubber bottom good or polyurethane good?
Rubber material itself poor ventilation, long wearing easily lead to beriberi. And summer rains, if the rain does not drain, will add story.
Q:What is rubber leather?
Special rubber refers to rubber with some special properties. The main contents are as follows: chloroprene rubber. CR, prepared by polymerization of chloroprene. With good overall performance, oil resistance, combustion resistance, oxidation resistance and ozone resistance. But its density is larger, it is easy to crystallize at room temperature, hard to store, cold resistance is poor. Nitrile rubber. Referred to as NBR, made by copolymerization of butadiene and acrylonitrile. Good oil resistance and aging resistance. It can be used in the air of 120 degrees Celsius or in the oil at 150 degrees centigrade for a long time. In addition, it also has water resistance, air tightness and excellent adhesive properties. Silicone rubber. The backbone consists of alternating atoms of silicon and oxygen, with organic groups on silicon atoms. High and low temperature, ozone resistance, good electrical insulation. Fluorine rubber. A synthetic rubber containing fluorine atoms in the molecular structure. Usually, the number of fluorine atoms in the fluorine containing unit in the copolymer is expressed as fluorine rubber 23, and the copolymer is two vinylidene fluoride and three fluorine vinyl chloride. Fluorine rubber, high temperature, oil resistance, chemical resistance. Polysulfide rubber. Condensation of two halides with sulfides of alkali or alkaline earth metals. Has excellent oil resistance and solvent resistance, but the strength is not high, aging resistance, poor processability, odor, and more with nbr. In addition, there are polyurethane rubber, epichlorohydrin rubber, acrylic rubber and so on.
Q:How can rubber be preserved without decay?
To preserve the rubber, do the following.1, to avoid long-term direct sunlight, the sun is too strong on the aging of rubber is killed, rubber is usually black, absorbing ability, so will cause the temperature rise, and then the physical properties change, the direct result is soft.2, avoid high temperature environment, said in front of direct sunlight will cause high temperature deformation. Another disadvantage of high temperatures is that it can cause rubber to melt.
Q:How to maintain and store the rubber material?
When storing, matters needing attention are:(1) should be stored in a ventilated, dry environment, the relative humidity of the air is 50% ~ 80%.(2) should be stored in non corrosive media, and away from the heat source, the temperature is about 5 degrees Celsius conditions(3) packing should be kept as far as possible without box stacking
Q:Will rubber products fade?
It looks like, especially if it's outdoors for a long time
Q:Rubber products labeled Huai gum can improve wear?
In accordance with the requirements of the inquiry, the tire carbon black is a special production, usually oil to produce, mainly in the heavy oil products, coal, coal tar and other raw materials as a result of incomplete combustion
Q:What does rubber mean?
Rubber is widely used in industry and life, and rubber products are also diversified and widely used.
