Paraffin Wax for Lubricated Paper
The first major type of crude oil, Paraffin wax, which is used in Lubricated Paper, industries and hygienic aims, widely.Paraffin wax has some shapes, such as Paraffin wax in solid shape and liquid paraffin.Paraffin wax suitable as corrosion protection coatings for industrial barrels and tanks. In addition, use in electrical insulation, textile, making Candles, Production of waterproof fabric and paper industries, Industrial Wax, Solid ink copy paper, Based lubrication products and Vaseline.
Paraffin wax has two major grades, they are light Paraffin wax and heavy Paraffin wax. These grades are divided to Fully refined paraffin wax and semi refined paraffin wax, also.
Fully refined paraffin wax, has oil content less than or up to 0.5%. It is white, transparent, tough and commonly use for candle making. Candles which are made by Fully refined paraffin wax, are snow white and have long lasting burning time.
Semi refined paraffin wax, not only use for making candle, but also apply for some other aims, such as surface waxing, polishing and lubrication. Semi refined paraffin wax has oil content up to 7%.
Description of Lubricated Paper
The lubrication mechanism in PVC was studied using calcium stearate and paraffin wax lubricants. Based on the results of the differential thermal analyses, percent haze, microscopy, metal release, Brabender fusion, and extrusion studies we have developed a new theory of PVC lubrication based on molecular structure. Lubricants containing polar groups, which preferentially wet the metal surface in the presence of PVC, such as calcium stearate, are excellent metal lubricants. Non‐polar lubricants which do not wet the metal surface, such as paraffin wax, allow PVC to stick to the metal surface. However, these lubricants work in combination with the metal wetting lubricants to make the lubricant layer more fluid, providing a better lubricating system than either lubricant alone. Lubrication between PVC primary particle flow units is similar to that at the metal surface with the polar PVC surface acting in a similar manner as the metal surface. We find the common classification of lubricants as internal or external to be deficient in explaining performance.
