Activated clay development prospects
Updated 2016-09-22 By:Leping Jiejing Bleaching Clay Co., Ltd  Visits:622

Activated clay is clay (mainly) of bentonite as raw material, the inorganic acidification treatment, then through water rinse, dry sorbent, appearance is milk white powder, odourless, tasteless, non-toxic, strong adsorption, can adsorption non-ferrous material, organic material。 Easy absorption of moisture in the air, placed too long will reduce the adsorption performance。 However, heated to 300 degrees Celsius above start losing water of crystallization, is a structural change, affect the fade effect。 Activated clay does not dissolve in water, organic solvents, and various kinds of oils, almost completely dissolved in hot caustic soda and hydrochloric acid, relative density 2。3 ~ 2。5, minimal swelling in water and oil。 Widely used in mineral oil, animal and plant oil, wax and organic liquid petroleum refining。 Also can be used as A desiccant moisture, alkaline antidote for medicine, vitamin A, B adsorbent, overlap contact agent of lubricating oil, fuel gas phase extract preparation, etc。, also can be used as A medium temperature polymerization catalysts, high temperature polymerization agent and manufacturing particles of clay materials。

In the past, people only know using bentonite as raw material of activated clay, actually otherwise, with characteristics of clay mineral can be used as a raw material of activated clay soil, such as montmorillonite clay, montmorillonite clay, sepiolite clay, attapulgite clay, etc.

众意彩票注册Kaolinite clay or kaolin clay (kaolin), is a family of kaolinite mineral as the main composition, texture, pure fine clay, appearance is white, such as shallow ash is lubricious, containing impurities was yellow, grey, black, etc. Dense clumps or loose earthy, soapy, hardness is less than the nails. The proportion of 2.4 to 2.6, dry after water imbibition. Refractoriness of up to 1770-1790 ℃. Low plasticity, small caking property, good insulation and chemical stability.

Pure kaolinite calcined after color white, the white degree can reach 80% 90%。 Montmorillonite clay, also known as bentonite, bentonite rock, spot, is a kind of montmorillonite as the main mineral composition of fine clay。 Look white, pink, shallow gray, light yellow, when impurity contamination can be a sage green, purple, brown and other dark color。 Loose earthy tarnish, dense block is waxy luster。 Hardness is 1 to 2, soft。 Block or earthy, slippery feeling。 The proportion of 2-3。 After absorbing water volume expansion, water quantity for the size of 8-15 times。 With high plasticity and good cohesiveness, suspension and gelation shaped in aqueous solution, but also has the characteristics of cation exchange。 Sepiolite clay is a kind of sepiolite as the main component of clay。 Appearance of brown spots, dark gray, gray color, the soil block, soft and light, hardness is 1 to 2, the proportion of 2。4 to 2。65, with viscosity and plasticity, hand touch of the slippery feeling。 After adding water can tune into a paste, dry of hammer can be used after leaving the hammer。 Attapulgite clay is a kind of attapulgite as the main component of clay, appearance and - like clay, especially with montmorillonite clay is very similar, and both often symbiosis。 Its field identification mark is appearance is earthy, show its, duck egg blue, grey, soil is exquisite, have slippery feeling, viscosity and plasticity when wet, dry after qualitative light, narrow。 And put it into the water, simmering and collapse are scattered into pieces, but not inflation。 And performance of attapulgite clay, sepiolite clay has a thermal stability, salt resistance and high adsorption and decolorization ability。 Hunan sea bubble stone become activated clay, zhejiang found b axis disordered kaolinite can also be activated clay, the successful development in shandong with water purifier residue as the raw material of activated clay。 Such activated clay materials is more widely。 But we say normally activated clay refers to using bentonite as raw material of activated clay?

Sea bubble stone activated clay, go through selection, such as acid activation process can be made into activated clay。 Water is selected, liquid-solid ratio is 5 ~ 10。 Water concentration after the suspension of 0。5% plus 0。5% of sulfuric acid or hydrochloric acid, boiling for 30 min, then filtering, washing, drying, grinding for products, namely decoloring rate reached to 93%, more than the requirement of national standard decoloring rate 90%。 Concave-convex rod clay has a reputation for "ten thousand USES of the thousand soil," yarrow, concave-convex rod activated clay (no acid activated clay) has the high decolorization rate, excluding the residual acid, etc。
