        The Important Usages of Diatomite

        copyfrom: Date:2016-11-14 viewed:439

             One of the important uses of diatomite is used to make filter aids. Through using powdered products of diatomite, rigid granules, suspended materials, colloidal particle and bacteria in liquid can be filtered out, which contributes to the filtration and purification of liquid.
        The main applications of diatomite filter-aid are listed as followed:
        (1) Seasonings: MSG, sauce and vinegar;
        (2) Beverages: beer, white oil, rice wine, fruit wines and grape wine and other kinds of drinks;
        (3) Medicines: antibiotics, artificial blood plasma, vitamins, liquids of boiled medicinal herbs and various kinds of liquid medicines;
        (4) Water processing: tap water, industrial water, industrial waste water disposal, swimming-pool water and the water in bath;
        (5) Chemical products: inorganic acid, organic acid, alkyd resin and titanium sulfate solution;
        (6) Industrial oils: lubricating oil, cooling oil in mechanical rolling , electric insulating oil, all kinds of engine oil, diesel oil, gasoline, kerosene and petrochemical industry;
        (7) Edible oil: rape oil, soybean oil, peanut oil, tea seed oil, sesame oil, palm oil, rice bran oil and lard;
        (8) Sugar industry: fructose syrup, high fructose syrup, cane sugar, glucose syrup, beta vulgaris sugar stevia sugar and honey.
        (9) others: enzyme preparation, vegetable oil, seaweed gel, electrolyte, dairy, citric acid, gelatin and bone glue etc.

        The second most important use of diatomite is to be used as functional fillings. It is mainly used in the aspects of coatings, plastics, rubber, medicine, toothpaste, abrasive materials and chemical reagents. For example, structural fillings can adjust the gloss and brightness of the coating. Besides, diatomite can be used as abrasive materials in silver polishing powder to polish the surface of metals. It can also be used as an adsorbent, for it can absorb 2.5 times as much water as its own mass. The specially processed diatomite powder seems still to be "dry", even after an addition of 50% of its mass.
            The main uses of diatomite are mainly concerned with the following several aspects
        Diatomite due to the features of thermal insulation, sound insulation, can be used as lightweight admixture to make cement, to make lightweight construction brick, fireproof construction materials and lightweight aggregate. The decorative boards made from diatomite has a good function of moderate regulating. Thereby, the amount of beneficial bacteria on the wall increases, which will benefit to resolve the pollution materials and keep the indoor air fresh.
            Diatomite due to its micro pore and its absorbing performance, is used as liquid filtration agent and bleaching materials in sugar, wine and other food industry and petroleum industry.
            Diatomite, in the industry of coating, paper-making, plastics, rubber, pesticides, fertilizers and others, is used as adsorbent, fortifiers and filling agent.
            Diatomite is used as filter materials of antibiotics, vitamins and herbal extracts in medical and pharmaceutical industry.
            Modified fine soil of diatomite, in environmental protection, is used as sewage purifying material.
            Diatomite, due to its high melting point, high thermal stability and acid resistance, is used as materials to produce the heat insulation bricks and refractory lime which can be widely used for various ceramic industry.
            Diatomite is also used as admixtures and catalyst carrier in petroleum industry.
            Diatomite is used as a soil conditioner to enhance soil’s capacities of water holding and fertility holding and air permeability.
            Diatomite, used as an additive in feed can promote the growth of livestock and improve the quality of the meat.
            Diatomite, mixed with carbon containing materials, salt water and something else, can be made into portable solid fuels.
            The diatomite can also be used as an anti-caking agent, the tip of a matchstick, an electric welding rod, the materials of sodium silicate and an explosive-material stabilizer.
        Diatomite can also be used as raw materials of ceramics, such as the manufacture of ceramic glaze tile and chemical porous ceramics; diatomite can also be used to manufacture molds for the production of optical glass (porcelain box).
            Diatomite is also used as a flexible abrasive materials(polishing agent).
            Diatomite is also used to produce vanadium catalyst carrier.
            Diatomite with poor quality can be used to make pottery particles as asphalt road fillings and cement blending materials.

        常见问题Common problem

        What’s diatomaceous earth stuffing?
        For applied structures of diatomite, fillings act as the second largest use of diatomite inferior to filter-aid It is of light-weight, soft-quality, multi-hole, sound insulation, heat-resistant, acid-resistant, large specific surface area as well as stable chemical property and other series of good characters, so diatomite is a kind of functional fillings wildly used in many industrial fields
        How about quality stability of products of your company?
        Raw materials of our company for producing diatomite filter-aid are completely from self-owned mine and high quality ores with SiO2 more than 85% are used for production Our company persists in inspecting all raw materials, intermediate products and additives and strictly implements ISO9001: 2000 quality management system standards and ISO14001: 2004 environmental management system standards during actual production Tracking for finished products is
        Functional Mechanism of Diatomite(diatomaceous earth) Filter-aid
        Circulate pre-coating liquid of diatomite again and again to make the first layer of diatomite deposited on the filter medium, and this process is called as pre-coating Then make a spot of diatomite added into original liquid timely, which is called as addition Along with process of filtration, the diatomite added mixes with impurities in the original liquid, depositing on the pre-coating layer, thus new pre-coating layers are formed constantly;
        Selection of Model of Diatomite (diatomaceous earth) Filter-aid
        Choosing right filter-aid model is crucial to success of use Since it’s different of filter machine, operating environment and technical requirement for each factory, different models of filter-aid in our company could be chosen randomly on the basis of ensuring clear filter liquid and getting most filtration quantities So generally on the premise of satisfying technical requirement, it is a must to search for maximal filtration speed, according
        How about chemical stability of Diatomite (diatomaceous earth) filter-aid?
        “Tosens” brand diatomite filter-aid has chemical stability and doesn’t’ produce chemical change with the suspension except for the hydrofluoric acid and also is not soluble in fluid phase; moreover, it has low heavy metal content and doesn’t contain poor impurities, dyeing, sand grains and unpleasant odor High-purity raw material, advanced production equipment and high-standard quality management system can fundamentally relieve the client
