Sanding disc specific classification and characteristics

Sandpaper paper in papermaking process, because each manufacturer 's equipment and technology is not the same , resulting in paper properties are quite different , and if we do not understand the paper 's performance during use , there may be some issues not properly controlled , thus affecting the quality of sandpaper , so the correct approach is necessary to  PINEZONE Mounted flap wheel master the use of paper .
    First, the paper has a positive and negative difference , to the proper use of planting sand surface . A grade paper , latex paper, heavy paper and paper is generally only one belt planting sand surface , some of which are planted sand surface web , there are the web is planted outside sand surface , requiring paper manufacturers indicated at the factory . B grade paper , C grade paper according to the different requirements of coarse -grained and smoothness select different planting sand surface , medium grained on both  PINEZONE cut off wheel sides can be used .
    Second, the weather unstable performance of the base paper . Everyone knows can be very absorbent paper , paper is no exception , with special attention in the storage and transportation process to strengthen waterproof, moisture protection, it should be moisture-proof paper packaging at the factory and do the proof packaging that is out of the box , especially in the South and more rainy weather , more should pay attention to moisture and humid climate .
    Third, the treated paper is preferably used in order to enhance water resistance and anti- glue paper penetration , do waterproof sandpaper , generally, the paper post-treatment should be used. Which is impregnated with the back-side or both sides of paper impregnated with processing , so can " plugging holes " , you can avoid a lot of glue glue into the paper , resulting in sticky sand is not strong , the impact grinding performance , but also some manufacturers of paper in the paper has been water treatment , do not reprocessed this is because the use of the paper coating or dipping method , and the resin molecules into the paper fiber , the fiber and surrounding , after the resin has cured to form a stable water- resistant , oil-resistant, preventing penetration of the solvent body structure , but the amount can not be dipping too large, otherwise it will increase the brittleness of sandpaper .
    Fourth, the paper can not be processed immediately put into production because of paper when processing through high temperature baking, resulting in fiber contraction , its moisture content is also greatly reduced , prone to brittle paper , glue sand-planting immediately if carried out , will result in breaks frequently affect production, the rate of decline in genuine , serious not normal continuous production . would be better  PINEZONE abrasive flap disc to store the paper treated three to five days after production ( summer hot weather should be a little longer ) , or using a humidifier process when dealing with paper, so can reduce the brittleness of the treated paper .
    Five paper factory should not be used just because paper in the papermaking process, the use of a certain amount of chemical additives, these additives have a reactive curing process , commonly referred to as the paper " aging process ", generally two paper should offline after fourteen hours before use , heavy abrasive paper, latex paper , A-level paper should be kept a week after use .
