    How to choose the lubricant of bag making machine non-woven bag making machine?
    2019-04-19

    Non-woven bag making machine can not repair the lubricating oil, how to choose the lubricant of the non-woven bag making machine? Lubricants are only required for their internal lubrication, but their choice is very simple, but in most cases it is best to adjust their internal and external lubrication to a certain extent.

    The internal and external lubrication function of a lubricant is determined by its chemical composition, polarity, and solubility in the polymer melt. For example, stearic acid monoglyceride is soluble in the polyvinyl chloride melt and has partial internal lubrication. Its internal lubrication function comes from the action of two polar hydroxyl groups in the molecule; while glyceryl tristearate has only external lubrication function. Because it has no hydroxyl groups in its molecule. Of course, the lubrication function is also affected by impurities and other additives contained in the lubricant.

    Non-woven bag making machine plastic lubricants range from natural materials such as montan wax, paraffin, mineral oil, animal and vegetable oils to various low molecular weight polymers such as low molecular weight fluororesins, silicone oils, low density polyethylene. Etc. More commonly used are some aliphatic compounds such as stearic acid, stearic acid soaps, and acid esters. And amide compounds.

    In the United States in 1981, more than 10,000 tons of lubricants were used in plastic processing. The total amides accounted for 45%, stearic acid and its derivatives accounted for 35%, and wax compounds were again. Some lubricants, such as oleic acid amide, stearic acid amide, and hard metal salts of fatty acids (cadmium citrate) are themselves excellent anti-stickers. Non-woven bag making machine Lubricating oil can be made into a good smoothness by adding 0.5%. Of course, fillers such as silica and clay are also the longest-lasting anti-sticking agents in an amount of 0.1-1.0%, which are often referred to as opening agents.
