High Quality Coal Mine Conveyor Belt - Oil Resistant Conveyor Belt – Zhengtan Metallurgy
High Quality Coal Mine Conveyor Belt - Oil Resistant Conveyor Belt – Zhengtan Metallurgy Detail:
Oil can have a very detrimental effect on the performance and life expectancy of a conveyor belt because it penetrates into the rubber causing it to swell and distort, often resulting in serious operational problems. Oil esistance can be divided into two sources–mineral oils and vegetable & animal oils and fats. Mineral oils are the most aggressive and demand a particularly high level of protection.
