Problems solved by technology

[0005] The emulsified oil currently used in coal mines is a synthetic product with 60% to 70% mineral oil as the base oil. It is called "emulsified oil". Since the raw material of this product is non-renewable petroleum resources, the price is affected by international petroleum products. The impact is great, oil resources are getting less and less, the price can only rise gradually, and there are also problems of polluting the environment
Although the concentrate has solved the base oil without adding mineral oil, it is an oil-in-water product with a high water content, and its anti-rust performance, lubricity and hard water resistance have certain limitations during the proportioning process.
There is also a certain phenomenon of oil and soap separation during use, which causes the filter screen to be blocked, and the filter screen needs to be cleaned frequently, and these precipitated oil soap and coal dust combine to form sticky matter that is difficult to clean, which will affect the use of the work site. Cause many adverse effects, the electro-hydraulic control system will block the filter components and other problems
