Abstract
A process for preparing granular bentone includes choosing white bentone, baking or drying in sun, adding sodium carbonate, pulverizing by 100-200 meshes, adding solution of sodium silicate and water, stirring, squeezing, baking and screening. The resultant bentone particles (0.8-4 mm) features high hydroscipicity, strength and caking performance, and high purity.
Description
Technical field
The present invention relates to a kind of process for preparing granular pentonite.
Background technology
Because the wilkinite water-absorbent is better relatively, thus be widely used in the construction work, but these bentonitic color and lusters are relatively poor, and impurity is more.
Summary of the invention
The object of the present invention is to provide a kind of technology simple, the process for preparing granular pentonite that cost is relatively low, the particle wilkinite water-absorbent of producing with this method is strong, and color and luster is pure white, and intensity is good, and impurity is few.
The objective of the invention is to be achieved through the following technical solutions:
A kind of process for preparing granular pentonite, its production stage is: select the oven dry of white wilkinite or dry, by weight the yellow soda ash that adds 0.02-0.05 part in every part of white wilkinite, putting into Raymond machine pulverizes, be ground into 100-200 order soil powder, the sodium silicate liquid that adds 0.03-0.06 part again adds 0.3-0.6 part water, stir, be pressed into cake with the extruding twin rollers, enter the drying machine oven dry, make moisture content≤10%, sieve then, the granule packaging of 0.8mm-4mm is got final product.
Physicals of the present invention is as follows: water-intake rate 〉=500%, expand 〉=15, pH value 〉=7, particle diameter 0.5-1.5mm, green compression strength＞130, moisture content≤10%, high proportion 0.6-0.82, ash≤190.
Advantage of the present invention is: the present invention is a kind of new production method, and adopts new prescription, and with the particle wilkinite good water absorption that the present invention produces, color and luster is pure white, intensity is hard, and the caking performance is good, and impurity is few, ash is low, can be used as cat litter and use, and also can be used as waterproof, impervious material.
Embodiment
Below in conjunction with concrete embodiment, the present invention is described in further detail.
A kind of process for preparing granular pentonite, its production stage is: select the oven dry of white wilkinite or dry, add 0.03 part yellow soda ash by weight in every part of white wilkinite, putting into Raymond machine pulverizes, be ground into 150 orders soil powder, add 0.04 part sodium silicate liquid again, add 0.4 part of water, stir, be pressed into cake with the extruding twin rollers, enter the drying machine oven dry, make moisture content≤10%, sieve then, the granule packaging of 0.8mm-4mm is got final product.
Claims (2)
1, a kind of process for preparing granular pentonite is characterized in that: the bentonitic production stage of particle is:
Select white wilkinite to dry or dry, add the yellow soda ash of 0.02-0.05 part by weight in every part of white wilkinite, put into Raymond machine and pulverize, be ground into 100-200 order soil powder, the sodium silicate liquid that adds 0.03-0.06 part again, add 0.3-0.6 part water, stir, be pressed into cake with the extruding twin rollers, enter the drying machine oven dry, make moisture content≤10%, sieve then, the granule packaging of 0.8mm-4mm is got final product.
2, process for preparing granular pentonite according to claim 1 is characterized in that: production stage is:
Select white wilkinite to dry or dry, the yellow soda ash that adds 0.03 part by weight in every part of white wilkinite is put into Raymond machine and is pulverized, and is ground into 150 orders soil powder, the sodium silicate liquid that adds 0.04 part again, add 0.4 part of water, stir, be pressed into cake with the extruding twin rollers, enter the drying machine oven dry, make moisture content≤10%, sieve then, the granule packaging of 0.8mm-4mm is got final product.
