Our company is made of high-quality bentonite clay as raw material, after cleaning, activation. Extrusion. Drying. Grinding and a series of process, production of activated white clay.
The white and pink, odorless and tasteless, non-toxic, good activity, strong adsorption, easy to absorb moisture in the air, such as placing too long or moisture will reduce its adsorption function, the use of appropriate heating (80-100 ℃) resurrection, if the above heating to 300 ℃ begins to lose water of crystallization, the structure change, affecting decolorization.
Activated Bleaching Earth is a clay (mainly bentonite) as raw material, the inorganic acid, followed by water rinsing, drying adsorbent made of, look for the milky white powder, odorless, tasteless, non-toxic, strong adsorption, can adsorb colored material, organic matter. Easy to absorb moisture in the air, place too long will reduce the adsorption properties. However, heated to 300 degrees Celsius above began to lose water of crystallization, the structure changes, effects of fading effect. Activated clay is insoluble in water, organic solvents and oils, almost completely soluble in hot caustic soda and hydrochloric acid, the relative density of 2.3 ~ 2.5, in water and oil swelling minima
1, selective adsorption ability, the decolorization rate high, with a low rate of oil, filtration speed, add less;
2, effectively remove grease total phospholipid, soap and trace metal ions, is a natural antioxidant;
3, removal of oil in aflatoxin, pesticide residues and other toxins and odor;
Acid number 4, after bleaching not rise, do not back color, clear and transparent, stable quality, long shelf life.
Refining production 5, especially suitable for mineral oil, vegetable oil, animal oil.
Methods: according to the amount (3% – 7%) of the product into the oil, heat the oil (in the reaction kettle or other container) 100~150 degrees Celsius or greater, evenly stirring for 10~20 minutes, to live fully absorbed and deposited soil. Heat 20~30 minutes, and then through the filter (filter layer filter or filter press).
Activated clay than the large surface area, strong adsorption capacity, high decoloration efficiency; activity was low, do not react with grease and other chemical substances; used for filtering liquid decolorization speed fast, residual liquid rate is low, such as edible oil bleaching, sugar decolorization decolorization; after the liquid is transparent and clear, stable quality, no smell, no to color, not acid; after using the product, after proper treatment can be used for the two time, it will not cause environmental pollution and other products and the advantages of wide application in adsorption, granular clay, carbonless copy paper with chromogenic agent
By 1, edible oil bleaching products are widely applicable to all types of vegetable oil, animal oil and mineral oil, such as soybean oil, rapeseed oil, peanut oil, cottonseed oil, sunflower oil, palm oil, coconut oil, castor oil, tea oil, corn germ oil, refined oil, sesame oil, tung oil, safflower oil etc.. 2, sugar decolorization decolorization products by the rich magnesium aluminum silicate purification refined sugar, its colour and lustre, reducing sugar content, pH, ion content, thionyl chloride ion content, protein content, sugar boiling temperature and calcium and magnesium ions content reached the current standard, save the decolorizing treatment costs about 60%. The filter cake after decolorization of mixed feed, reduce environmental pollution, to achieve comprehensive utilization.
3, environmental odor absorbing agent level product has good adsorption odor, odor can eliminate the refrigerator, pet bedroom, toilet and other places.
