Sepiolite Clay Powder Uses

Sepiolite powder has a wide range of uses in industrial and agricultural production: as an excellent raw material for preparing mud in geothermal drilling and deep-sea oil drilling; in the oil and oil industry as an oil adsorbent, decolorizing agent and purifying agent; in the pharmaceutical industry It is used as ion exchanger, purifying agent and husk agent in China, as a leavening agent in the glucose industry, as a clarifying agent in the brewing industry; in the ceramic industry, it can be used as a raw material for glass enamel and a binder for ceramic mud, etc.;
Its specific main uses are:
Deodorant for environmental protection sepiolite powder has strong adsorption capacity to the foul odor molecules produced by industrial leaves, such as putrescine, cadaverine, phenylpyrrole and butanol, etc. The most effective.
As a catalyst carrier: it is used in industry to separate metal compounds and asphalt, and in the process of removing hydrogen sulfide or fractionating oxygen.
Used in polybasic resin: sepiolite powder is used as thickener and thixotropic agent in polybasic resin liquid, which can prevent pigment precipitation and sinking of polybasic resin after use.
Used in asphalt cladding: The most suitable asphalt cladding for roofs and ship bottoms is sepiolite powder, which is harmless to the human body, but has overturning and thixotropy properties, improving the performance of the final product.
Used in coatings: It can also act as a suspending agent to prevent pigments from precipitating during storage. Sepiolite powder as a thickener also provides suitable viscosity. As a thixotrope, no precipitation occurs when the paint is applied with a brush, roller or spray.
Pharmaceutical use: Sepiolite powder has a huge active surface area, which can retain the active product, so it can be used as a pharmaceutical excipient. Sepiolite powder can form a gel property, it can be used to protect the semipermeable membrane of intestinal fluid, covering the intestinal wall and stomach wall. In addition, it has the function of controlling the pH value, so it can be used as an antacid substance in the treatment of hyperacidity.
As a decolorizing agent: use sepiolite powder to decolorize paraffin, petroleum and vegetable oil.
As a filter aid: Sepiolite powder in needle shape is a very useful filter aid. The filter aid ability of sepiolite powder is combined with its adsorption, which can be used in the process of decolorizing oil and producing glucose. as a clarifying agent.
As an anti-caking agent: because sepiolite powder has a huge surface area, adsorption and semi-adsorption can occur on it, so that it can maintain a variety of liquids in a high proportion, and control the humidity of the mixture for anti-caking. Pharmacy.
As a carrier of pesticides: Most pesticides are highly effective pesticides, which are preferentially adsorbed by Piolite. The less toxic ingredients such as aromatic substances have a lower degree of adsorption, the latter such as methyl furan, ethane furan or lemon oil, etc., they greatly enhance the aroma of tobacco, can improve product quality, reduce toxicity, and improve economic benefits. 
For plastisol: plastisol is a fine PVc (polyvinyl chloride) with particles dispersed in one or more plasticizers. In order to obtain a stable and uniform colloid with alteration and suitable for spraying, sepiolite powder treated with surfactant can be used.
Used in rubber industry: as an inorganic filler, sepiolite powder can play the role of semi-reinforced filler, which can increase the modulus, tensile strength, hardness and tear resistance of rubber, and obtain better aging characteristics.
For animal nutrition: Because sepiolite powder has special adsorption, free watering, anti-caking, chemical inertness and non-toxicity, there are many kinds of animal-shaped sepiolite powder that can be used as animal nutrition.
Production accelerator: the use of sepiolite powder as feed binder can improve the efficiency of feed better than other binders.
As an additive carrier: adding vitamins, minerals, antibiotics, etc. to the feed is a widely used feeding technology. Sepiolite powder particles of 60-120 mesh size are used as a carrier to uniformly mix trace additives.
As feed binder: Sepiolite powder as binder is better than other products.
As a purifying agent: Clay with high exchange capacity can be used as a softener for hard water, exchanging calcium and magnesium ions in water with cations of clay. Replacing 30% of the fatty acids with sepiolite powder improved the performance of the soap.
Used in cosmetics: Sepiolite powder can be used as thickener and thixotropic agent in cosmetics to provide suitable viscosity to ointment and grease. It can also be used as a pigment suspending agent.
Used in agriculture: Using the adsorption properties of sepiolite powder and the property of forming a stable suspension, it can be used in agriculture, mainly in the following two aspects:
(1) As a soil aggregate structure promoter.
(2) As a fluid carrier for seeds after germination.
For seed coating: Grind the sepiolite into fine particles with a size of 5u. After mixing the pesticides and fertilizers, add the seeds and mix them well as a seed coating to improve the germination rate and increase agricultural production.
As a fertilizer suspension: Suspended fertilizers are preferable to fertilizer solutions because the amount of nitrogen, phosphorus or potassium compounds in fertilizers is not limited by their solubility.
As lubricating oil thickener: sepiolite powder treated with hydrocarbyl xylene amine chloride, 15% can be dispersed in diisooctyl, silicone 500 and mineral oil containing 50% polybutene, producing High degree of grease.
For carbonless copy paper: This paper produces fast and good print quality without high pressure.
Oil drilling mud: During the drilling process, in order to remove the cuttings in the drilling process, it is necessary to continuously circulate the mud. The mud is returned from the well to the ground mud pool to deposit the cuttings and removed, so as to keep the hole clean and ensure the hole is clean. Safe and normal drilling inside.
