After being treated by Raymond mill, diatomite is mainly used as filler in papermaking process, which can not only reduce raw materials, but also increase the new functions and characteristics of paper. Therefore, diatomite has been widely used. Here are some main latest applications.
It can be used as filler for flame retardant sound-absorbing paper (board). Diatomite has good flame retardant and sound absorption characteristics, and can be mixed with pulp to manufacture high-grade decorative paper and paperboard for indoor decoration. The filling proportion can be up to more than 60%. For example, an imported decorative paperboard for indoor ceiling, the content of diatomite is as high as 77%; Advanced wallpaper for quiet room, with Diatomite Content of 65%.
It can be used as oil seal paper (board) packing. Oil seal paper pad paperboard is a new sealing material used in mechanical transmission part. Using the wear resistance and oil absorption expansibility of diatomite, it has been successfully used as oil seal paper filler in recent years. Diatomite has certain expansibility after saturated adsorption of grease, so as to prevent the overflow of mechanical oil and improve the sealing effect.
It can be applied to cigarette paper filler. Diatomite filled cigarette paper can adjust the combustion speed, improve the air permeability of the paper, and significantly reduce the content of tar and other harmful substances in the cigarette.
It can be used as filling agent for fruit growing paper and seedling mold casting container. A domestic enterprise uses low-quality diatomite raw materials and is used to manufacture fruit growing paper after special pretreatment. It is said to have a good effect of heat preservation and moisture retention and promoting fruit growth. The modified diatomite filled seedling raising paper mold casting container is used for agricultural seedling raising. It is said to have the effects of sterilization, slow application, heat preservation, moisturizing and promoting plant growth. It can be applied to filter paper (board) filler.
Diatomite has been widely used as a filler for alcohol, beverage, food, medicine, oral liquid, purified water, industrial oil filter element and fine chemical filter paper or paperboard with special purification requirements. Filling diatomite in filter paper can effectively improve the clarity and filtration efficiency of filtered liquid. Diatomite filler modified with silver or other compounds with bactericidal (inhibitory) function can produce filter paper and paperboard with bactericidal (inhibitory) function.
