Analysis of Engine Selection for Underground Internal Combustion Scrapers

With the development of automobile industry, the production of tire mold increased year by year in our country.The surface integrity of tire mold, end molded equipment in tire production line, being determines tire's exterior and quality.The Teflon coating is often used for protect the surface integrity on the market today.This article introduces advantages and disadvantages of Teflon, extremely low hardness and shorter service-life and there is potential menace to the environment and body healthy.The DLC coating has exceptional hardness and environmentally friendly.But its internal stresses have very big internal stresses and poorer hydrophobicity the Teflon.Based on the analyses for property of fluorinated diamond-like(F-DLC), fluorine is helpful reduce internal stresses and improve hydrophobicity.The article produces a formulation with F-DLC used in tire mold.
