Abstract
The invention relates to an albite powder whitening method. The process of the method comprises: using albite powder with a particle size of no less than 200 mesh as a raw material; adding a small amount of chloride powder into the albite powder; mixing the powder and subjecting the mixed powder to ball-milling for 2 to 10 hours; and calcining the ball-milled powder at 800 to 900 DEG C for 0.5 to 2 hours. The weight ratio of the albite powder to the added chloride powder is 10-50:1; the chloride may be sodium chloride, aluminum chloride or potassium chloride; and the whiteness of the processed albite powder is over 85 percent and can meet the requirements of actual use.
Description
Technical field:
The present invention relates to the method that a kind of albite in powder brightens, what be specifically related to is to add a certain amount of muriate high-temperature calcination in albite in powder, to the method for whitening of albite.This albite in powder that brightens is applied to fields such as pottery, glass, chemical industry.
Background technology:
Albite is a kind of common feldspar mineral, is the aluminosilicate (NaAlSi of sodium
3O
8).Albite is widely used in many industries such as ceramic industry, paper industry, rubber plastic industry, building materials industry, chemical industry, paint industry.But often some melanocratic minerals of association and albite particle surface adsorb some pigment ions in the albite mineral, influence the whiteness of raw ore and product, reduce the quality of product, limited the range of application of product, become the major obstacle that the albite processing industry is adjusted the product mix, opened up a market.The major cause that causes albite to cause look is to cause the colored foreign ion owing to wherein contain iron, titanium etc.Therefore the research of removing and cause the look ion, improve its whiteness is significant.
The method of whitening that the purpose of this invention is to provide a kind of albite in powder.
Bright content:
For achieving the above object, the technical solution used in the present invention is: the method that a kind of albite in powder brightens, and its content is: be raw material with the albite in powder, according to the following steps albite in powder brightened:
(1) albite in powder is 10-50 by weight with muriate: 1 mixes, ball milling 2-10 hour.
(2) powder behind the ball milling was calcined 0.5-2 hour in 800-900 ℃, naturally cooling obtains product.
The related content of such scheme is explained as follows:
1, the granularity of albite is greater than 200 orders, and the muriate of adding can be sodium-chlor or Repone K or aluminum chloride.Fully ball milling makes powder to mix.
2, the powder behind the ball milling is calcined in 800-900 ℃, makes iron in muriate and the albite in powder, titanium etc. cause the look ion and forms volatile iron(ic) chloride or titanium tetrachloride, thereby the whiteness of albite is improved.
Method of the present invention is by the processing to albite in powder, obtain whiteness greater than 80% powder, its whitening process adopts and adds sodium-chlor or Repone K or aluminum chloride, after fully ball milling mixes, calcining in 800-900 ℃, make iron in muriate and the albite, titanium etc. cause the look ion and form volatile iron(ic) chloride or titanium tetrachloride, thereby the whiteness that makes albite reaches the degree of production application greater than 80%.
Specific embodiments
Example 1:
1, raw material: Zaozhuang, Shandong albite breeze, granularity are 200 orders, and whiteness is 57.9%.
2, be to mix ball milling 10 hour at 25: 1 by weight with albite in powder and sodium-chlor.
3, the powder behind the ball milling was calcined 2 hours in 800 ℃, naturally cooling obtains product.Whiteness is 86.2%.
Example 2:
1, raw material: Zaozhuang, Shandong albite breeze, granularity are 500 orders, and whiteness is 62.6%.
2, be to mix ball milling 6 hour at 15: 1 by weight with albite in powder and Repone K.
3, the powder behind the ball milling was calcined 1.5 hours in 820 ℃, naturally cooling obtains product.Whiteness is 88.5%.
Example 3:
1, raw material: Zaozhuang, Shandong albite breeze, granularity are 400 orders, and whiteness is 62.6%.
2, be to mix ball milling 6 hour at 40: 1 by weight with albite in powder and aluminum chloride.
3, the powder behind the ball milling was calcined 1 hour in 880 ℃, naturally cooling obtains product.Whiteness is 87.4%.
Claims (2)
1. method that albite in powder brightens is characterized in that: add a certain amount of muriate in albite in powder, calcine in certain temperature, according to the following steps albite in powder is brightened:
(1) albite in powder is 10-50 by weight with muriate: 1 mixes, and ball milling 2-10 hour.
(2) mixture behind the ball milling was calcined 0.5-2 hour in 800-900 ℃, naturally cooling obtains product.
2. method according to claim 1 is characterized in that: in the step 1, muriate is a sodium-chlor, or aluminum chloride, or Repone K.
