How silicone elbow works in a car
Produce a car without a variety of components is known to all. The auto silicone hose is one of them. The car now already become an indispensable means of transportation. The car can be seen everywhere, and parts need more strictly on select material, determine which kind of material is more suitable for pipe the role of the top priority in the car. So, how to distinguish the material in automobile?
The role of auto hose is mainly for transmitting gas, liquid, paddle body or particles, such as adaptability and different material and different environments have different choice of material nature. But as automotive rubber hose, PVC and silicone properties and get to know each other, so the function and direction are basic to know each other, so in the car they exactly how to distinguish?
PVC pipe is made of polyvinyl chloride resin and stabilizer, lubricant, etc. with hot pressure injection molding machine extrusion molding, the main performance, electrical insulation; Good chemical stability; Self-extinguishing; Low water absorption; Easy to bond, can withstand high temperature about 40°. The main equipment industrial gas, liquid transportation, household sewer pipe, water pipe and so on. But it has environmental problems such as plasticizer added, anti-aging agent and other major accessories are toxic, plasticizer in daily use of PVC plastic, mainly use dibutyl terephthalate, dioctyl phthalate and so on, these chemicals are toxic.
Silicone rubber belongs to high polymer material, it has to do with the material of PVC is different in the ontology on strengthening basic performance to ascension, resistance to high temperature (250-300) and low temperature (- 40-60) function has some physical stability, but also suffered repeated harsh and sterilization condition, excellent for deformation capacity and a small (20048 hours not greater than 50%), breakdown voltage (20 to 25 kv/mm), ozone resistance, uv resistance. Characteristics such as radiation resistance, special silicone rubber with oil resistance function. Silicone hose is widely used, the automobile silicone hose will be the direction of the development of the silicone tube.
