Brown red, brick red, grey black etc.；Have wax-like, earthy or greasy luster；For bentonite some loosely such as soil, the densification also having is hard.It is main
It is silica, alundum (Al2O3) and water to want chemical composition, also contains the elements such as iron, magnesium, calcium, sodium, potassium, Na2O and CaO content
Bentonitic physicochemical properties and process technology performance are influenced quite big.Montmorillonite mineral category monoclinic system is usually in earthy
Block, white, sometimes with the colors such as pale red, light green, yellowish.Dull.Hardness 1~2,2~3g/cm of density3.It can by montmorillonite
Type, content and the layer charge size of exchange cation, bentonite can be divided into sodium bentonite (alkaline soil)), calcium-base bentonite
(alkaline earth soil), natural bleaching are native (acid soil or Emathlite), and wherein calcium-base bentonite includes calcium sodium base and calcium and magnesium base etc. again.
Bentonite have strong hygroscopicity and dilatancy, the water of adsorbable 8~15 times of own vols, volume expansion up to several times extremely
30 times；As a form of gel and suspension can be dispersed into aqueous medium, this medium solution has certain viscosity, variability and profit
Slip；There is stronger cation exchange capacity (CEC)；There are certain adsorption capacity, maximum adsorption to various gases, liquid, organic substance
Amount is up to 5 times of weight of itself；The admixture of it and water, mud or fine sand has plasticity and cohesiveness；With surface-active
Acid bleaching soil can adsorb coloured ion.
Invention content
Goal of the invention：The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of dry effect
Fruit is good, can regenerate the bentonite deodorizing desiccant reused.
In order to solve the above-mentioned technical problem, the invention discloses a kind of bentonite deodorizing desiccants, including following parts by weight
Component：
Wherein, the method for modifying of the modified alta-mud is：By the honed 300 mesh sieve of bentonite origin miberal powder, 100 DEG C or less dry
Dry 2~3h is then added to 3~4h of processing in acid solution, reprocesses 1~2h with sodium salt solution after filtering, be finally filtered, washed
After being 6~7,150~200 degrees Celsius of 2~3h of processing to pH both.
Preferably, smectite content is not less than 60% in the bentonite raw ore.
The acid solution is sulfuric acid solution, and pH is 2~3.
The sodium salt solution is sodium chloride or metabisulfite solution, a concentration of 20~40wt%.
The sodium chloride is fused calcium chloride.
The present invention also provides the preparation methods of above-mentioned bentonite drier, by the modified alta-mud, sodium chloride, sulfuric acid
Calcium, activated carbon powder and nanometer titanium dioxide titanium valve be added in acid solution be uniformly mixed, be filtered, washed to neutrality, after drying with
Bamboo fibre is uniformly mixed, and is fitted into nonwoven fabrics package bag.
The pH value of the acid solution is 2~4, acid solution and modified alta-mud, sodium chloride, calcium sulfate, activated carbon powder
Mixing quality ratio with the solid powder of nanometer titanium dioxide titanium valve composition is 1~2:1.
