Non-woven bag-making machine in the maintenance of lubricating oil, non-woven bag-making machine lubricants how to choose? Lubricants require only internal lubrication
Then their choice is very simple, but most of the time it is necessary to adjust their internal and external lubrication to a certain extent as the best.
The internal and external lubrication function of a lubricant is determined by its chemical composition, polarity, and solubility in a polymer melt. For example, hard
Lipid monoglycerides can be dissolved in polyvinyl chloride melt and have a part of internal lubrication function. Its internal lubrication function comes from the two polar hydroxyl groups in the molecule
Use; Tristearate, on the other hand, has only external lubrication because it has no hydroxyl groups in its molecules. Of course, the lubrication function is also affected by the impurities contained in the lubricant
And other additives.
There are many kinds of lubricants used in non-woven bag making machine, such as lignite wax, paraffin wax, mineral oil, animal and vegetable oil and other natural substances
A variety of low molecular weight polymers such as low molecular fluorine resin, silicone oil, low density polyethylene, etc., are commonly used in aliphatic combination
Products, such as stearic acid, stearic acid soap, acid ester. And amides.
In 1981, more than 10,000 tons of lubricants were used in the processing of plastics in the United States, with 45% of total amides and 35% of stearic acids and their derivatives
The second is wax compounds and so on. Some lubricants, such as oleic acid amide, stearic acid amide, fatty acid metal salt hard (fatty acid cadmium) and so on are also good in themselves
It's an anti-sticking agent. Non-woven bag-making machine lubricating oil as long as 0.5% can make the film has a good smooth. Of course silicon dioxide, clay this
Class a fillers are also the longest used anti-paste agents, with the dosage of 0.1-1.0%. They are often referred to as opening agents.
