Can be used as flame retardant sound-absorbing paper (board) fillers. Diatomaceous earth has a good flame-retardant sound-absorbing properties, and can be mixed with pulp to manufacture high-grade decorative paper and cardboard for interior decoration. The filling rate can be as high as 60% or more. Such as an imported cardboard ceiling for indoor ceiling decoration, diatomite content as high as 77%; for the mute room of advanced wallpaper, diatomaceous earth content of 65%.
Can be used as oil seal paper (board) filler. Oil seal paper pad is a new sealing material for mechanical transmission. The use of diatomite has the advantages of wear resistance and oil absorption swelling. It has been successfully used in oil seal paper fillers in recent years. After diatomite saturated adsorption of grease, it has a certain degree of swelling to prevent mechanical oil spillage and improve the sealing effect.
The characteristic application is cigarette paper filler. Diatomaceous earth plus filling cigarette paper can adjust the burning rate, increase the air permeability of the paper, and significantly reduce the content of tar and other harmful substances in the cigarette.
The application features are the fruit growing paper and the seedling filling container filling agent. An enterprise in China uses low-quality diatomite raw materials and special pretreatments to produce fruit-making papers. It is said to have good heat preservation and moisturizing effects and promote fruit growth. The modified diatomaceous earth is filled with seedling paper die casting containers for agricultural seedlings, which are said to have the effects of sterilization, slow application, heat preservation, moisturizing and promotion of plant growth.
It can be applied to filter paper (board) fillers. Diatomaceous earth has been widely used as a filler for filter paper or paperboard for liquors, beverages, foods, medicines, oral liquids, purified water, industrial oil filter elements and fine chemicals. Filling diatomaceous earth with filter paper can effectively improve the clarity and filtration efficiency of the filtered liquid. Diatomaceous earth fillers modified with silver or other compounds with fungicidal functions can produce filter papers and paperboards with fungicidal functions. It can also be used as a battery separator filler. Diatomaceous earth is added to the mixed pulp for manufacturing a battery separator, and the porosity of the diatomaceous earth is utilized to increase the porosity of the battery separator to reduce the resistance of the battery separator. However, excessive addition of diatomaceous earth will reduce the mechanical strength and service life of the battery separator.
Can be used as deodorant paper filler. At present, deodorant papers on the market are mainly activated carbon paper, zeolite paper, ortho-aluminophosphate paper, and diatomaceous earth is used for deodorizing paper to remove the odor generated in daily life or industry, mainly because of its porosity and high porosity. , physical surface area, strong adsorption characteristics of physical deodorant. Deodorized paper can be used to deodorise the refrigerator, deodorizing the home, car deodorant and so on.
It can be used as absorbent for water-absorbing packaging paper. The purified diatomite is a kind of natural mineral that does not harm the human body. The absorbent fresh paper and paperboard manufactured by using its porous and highly absorbent properties are mainly used for the storage and packaging of food, and can also be used for the packaging of medicine and daily necessities. material. Absorbent cling paper is used for the packaging of aquatic products or meat products. It can maintain the moisture and freshness of aquatic products or meat, prevent external pollution, and absorb aquatic products or meat may leak during transportation and storage. Liquid. It is used for the packaging and storage of fruits, vegetables, cakes and other foods, can maintain the moisture of foods, block the penetration of external odors and other pollutants, and prevent the invasion of flies, bacteria and other organisms.
Can be used as a filler for decorative paper. Decorative paper is a decorative material that is used to cover the surface of a wood product to provide better surface smoothness and beauty. Diatomite can replace some of the expensive pigments in decorative paper to increase the paper's bulk, opacity, adhesion, abrasion resistance, and drying properties, maintaining dimensional stability and wet deformation.
