Natural rubber I will talk about rubber first, let's talk about how we can change and manipulate its natural state in order to take advantage of natural rubber. (Slide 2) Natural rubber is an excellent engineering material used as the main material of many daily necessities. The most common one is a car tire, which will be explained later. (Slide 3) Natural rubber is obtained from milky white liquid found in many plants, but synthetic rubber is made of unsaturated hydrocarbon (essentially meaning there are carbon atoms in the rubber molecule) .
There are various kinds of rubber such as synthetic rubber, silicone rubber, ethylene-propylene, natural rubber, butyl natural rubber, elastomer, liquid silicone rubber, etc. Industrial rubber materials are mechanical rubber products, elevators and conveyor belts, rubber hoses, vibration damping products, molded rubber products, transmission belts, Weatherstripping products, rubber products, films and films. Mechanical rubber products such as vibration damping devices, wiper blades and body seals are the largest products in the world market. Rubber materials such as hats, containers and seals are commonly used in the pharmaceutical and medical fields to protect products from environmental contaminants or from any contamination. Rubber products with high heat resistance, moisture resistance and ozone gas like condenser packaging have great value in the industry
Natural rubber is a large-scale industrial raw material worldwide, and the dual nature of industrial products and agricultural products is widely used in industrial, agriculture, defense, transportation, medical care and everyday life. Natural rubber, steel, oil, coal are the four major industrial raw materials. However, the production and consumption of rubber promoters is very heterogeneous in geographical distribution and is mainly produced in China. Mixing in blender, rolling mill and rolling mill for rolling operation, rubber has good effect of wrapping roller and rubber promoter, otherwise it is difficult to carry out smoothly.
