I believe everyone is already familiar with diatomite; previous articles have also provided detailed information on it. So, what are the applications of diatomite as a functional filler? Linjiang Xinghui Diatomite Filtration Aid Company will give you a detailed explanation below. (1) Special diatomite functional filler for centrifugal casting (tube) coatings: Centrifugal casting (tube) coatings prepared from diatomite that has been treated using appropriate processes, along with binders, suspending agents, and additives, can adjust the thermal resistance of the casting system and control the cooling rate of the castings (tubes). This helps to extend the lifespan of the molds used in hot-mold centrifugal casting, while ensuring that the microstructural properties and mechanical characteristics of the castings meet the required standards. (2) Diatomaceous earth functional filler for exterior (interior) wall coatings: In coatings, the unique porous particle structure of diatomaceous earth can make a smooth coating appear slightly rough, creating a matte effect. Moreover, diatomaceous earth helps to regulate the adhesion between the coating and the substrate, preventing cracking in the coating. Additionally, due to its porosity, diatomaceous earth enables viscous paints to dry quickly. (3) Functional fillers of diatomite for the rubber industry: The unique particle structure of diatomite enables it to serve as a reinforcing material in products such as polysilicon rubber and mechanical rubber, thereby enhancing or improving the heat resistance, wear resistance, sealing properties, and leak prevention capabilities of rubber products. (4) Paper industry: cigarette paper, filter paper and various packaging papers, printing paper, household paper, office paper, and other types of paper-making fillers. Advantages of using diatomite: It is lightweight and soft, with a fineness ranging from 120 to 1200 mesh. The addition of diatomite makes paper smoother, lighter in weight, and stronger; it also reduces expansion due to changes in humidity. In cigarette paper, it can help regulate the burning rate. It has no toxic side effects, and in filter paper, it can improve the filtering speed and clarity. (5) Feed industry: pigs, chickens, ducks, geese, pigeons, various fish, birds, and fillers for various feeds. Advantages of using diatomite: It has a neutral pH and is non-toxic. Diatomite powder features a unique pore structure; it is light in weight and soft in texture, with high porosity and strong adsorption capacity. It results in a light and gentle color. When mixed into feed, it disperses evenly and binds with the feed particles, making it difficult for it to separate out. After being consumed by livestock and poultry, it aids digestion and helps to absorb bacteria from their digestive tracts, thereby enhancing their health and strengthening their bones. When used in fish ponds, it improves water quality by making it clearer and more breathable, thus increasing the survival rate of aquatic organisms. (6) Friction material industry: Used as a filler in vehicle brake pads to improve wear and heat resistance. (7) Polishing materials industry: Used as a filler in polishing paste products for automobiles, furniture, as well as silver, copper, and stainless steel utensils. Advantages of using diatomite: it has a soft texture, strong lubricating properties, and a fineness ranging from 120 to 1200 mesh. (8) Cosmetics industry: Can be used as a filler in toothpaste and cosmetics. (9) Daily-use ceramics industry: It can be used as a raw material for microporous filtering ceramics. (10) Mosquito coil industry: Diatomaceous earth is used as a filler in mosquito coils to regulate the burning rate and reduce smoke. (11) Latex industry: Diatomaceous earth is used as an insulator inside balloons to facilitate demolding. (12) Others: Diatomite can be used as a modifier filler for asphalt pavements, an additive in drilling cement, and a cement admixture, among other applications. The above is an introduction to the application areas of diatomite as a functional filler. I hope it will be helpful to everyone.
