Q:Are natural latex rubber products?
In the fresh latex without any substance, the rubber hydrocarbon accounts for only 20%-40% of the total amount, and the remainder is a small amount of non rubber components and water.
Q:What is the cause of the bursting of rubber products and how should they be improved?
Improvement measures: 1.. Adjust the molding sulfuration temperature, adjust the temperature of the upper and lower plate. 2. adjust the exhaust distance and exhaust time. 3. in strict accordance with the mixing process standards or adjust the formula and mixing process, avoid the use of time is too long to place material (fast cooked). 4., in the explosive edge position plus running trough. 5. control the weight of a single adhesive.
Q:What is the difference between vulcanized rubber and butyl rubber?
Nitrile butadiene rubber is prepared by polymerization of butadiene and acrylonitrile by emulsion polymerization. Nitrile rubber is mainly produced by low temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and strong adhesive force. Its disadvantage is poor resistance to low temperature, poor ozone resistance
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:How can rubber products prevent fading?
That is to add UV absorbers, white, then add more titanium dioxide, there is no good way, as well as your choice of pigment, as far as possible difficult to fade, such as inorganic pigments.
Q:What are the ingredients in the tires?
Tires include rubber, polymers, sulfur, carbon black, and other chemicals. Each tire contains more than 150 components, so in the tire production process, from raw material processing to the tire baking to the end, the process is complicated and long.
Q:Natural rubber, general rubber, synthetic rubber. Are these all rubber products?
Not rubber products, rubber classification, rubber is divided into natural and synthetic rubber, synthetic rubber and general rubber and special rubber! The so-called rubber products refers to the use of rubber as raw materials to produce products, such as tires, belts, conveyor belts and so on.
Q:How can rubber and mould not be bonded when producing rubber products?
When rubber products are made, rubber and mould can not be bonded:1, abrasives to be polished, coating treatment, to achieve the most smooth surface and high temperature corrosion resistance requirements!2, formula design, less use of sticky, easy to corrosive materials;3, curing process should meet the requirements of formula design!
Q:What are the causes of fracture in rubber products?
If it is because of aging and fracture, this is a normal phenomenon, is not a problem in the safe use period, there is to pay attention to the storage environment, avoid direct sunlight, the best placed in the shade, not stored in a humid environment.
Q:Rubber products are not allowed to touch oil products, but why can rubber gloves be contacted daily? What's the point?
Most rubber materials are not resistant to oil, some rubber materials are resistant to oil, such as nitrile rubber, etc., the family commonly used detergent on rubber gloves did not affect.
