Abstract
The invention provides a process of preparing paste formed attapulgite clay. The key points of the technical proposal include: the process of preparing paste formed attapulgite clay comprises the steps of pulping, sodium treatment, acidizing treatment, water washing and impurity screening out, and the mud obtained is subjected to precipitation to obtain the paste formed attapulgite clay. The attapulgite ore mud is subjected to the steps of sodium treatment, acidizing treatment, water washing and impurity screening out, and become natural gel with good thixotropy and stickiness, and the pH value is neutral. The attapulgite clay obtained by the preparation process of the invention has viscosity, expansion capacity, colloid value, whiteness degree, specific surface area, adsorbability and dirt removing power greatly improved, and the invention is suitably applied to the production of the paste formed attapulgite clay.
Description
Technical field:
The present invention relates to the production technique of clay, be specifically related to a kind of production technique of paste attapulgite clay.
Background technology:
The Attapulgite raw ore is through after the wet beneficiation, utilize Attapulgite ore pul making production technique, can effectively improve the utilization ratio in Attapulgite ore deposit and the Attapulgite content in ore deposit, can deep processing be expensive goods, handle than also needing further to carry out modification in the high product but will be applied in the specification of quality condition.
The Chinese patent Granted publication number is: CN1224463C, Granted publication day: on October 26th, 2005, name is called " Attapulgite wet beneficiation craft ", the Chinese patent Granted publication number is: CN1248984C, Granted publication day: on April 5th, 2006, name is called " high-purity attapulgite and preparation method thereof ", the Chinese patent Granted publication number is: CN1287965C, Granted publication day: on December 6th, 2006, name is called " Attapulgite ore pul making production technique ", the Chinese patent Granted publication number is: CN100344368C, Granted publication day: on October 24th, 2007, name is called " a kind of method for preparing high-purity attapulgite ", above-mentioned patent has all been set forth the method for purification of attapulgite clay, and in actual industrial production, the solid-liquid separation of Concavo-convex stick after purifying mud remains a difficult problem, and its complex manufacturing and production cost are also than higher.
Summary of the invention:
The objective of the invention is to overcome weak point in the prior art, a kind of production technique of paste attapulgite clay is provided.
The production technique of paste attapulgite clay is: pulping, sodium processing, acidification, washing and sieve decon, the mud of process post precipitation is paste attapulgite clay.
The production technique of paste attapulgite clay is in the new invention of Attapulgite ore pul making production technique basis the next item up.
The inventor is in " the Attapulgite ore pul making production technique " of on January 6th, 2004 application, and the Chinese patent Granted publication number is: CN1287965C, Granted publication day: on December 6th, 2006.
Attapulgite ore pul making production technique is: will stir in the Attapulgite ore deposit input stirrer, after forcing machine is squeezed into sheet, import once more in the stirrer and stir, natural drying after forcing machine is squeezed into sheet, air dried Attapulgite ore deposit is transported in the feed reservoir soaks, dash with air pump and to turn over, post precipitation is emitted immersion water, the sieve decon in the input work in-process pond, is soaked again, dash with air pump and to turn over, post precipitation is emitted immersion water, and the slurry transportation of post precipitation is arrived in the finished product pond, is Attapulgite sludge slurry finished product.
The present invention is achieved by following technical proposals:
The production technique of paste attapulgite clay is: (1) selects for use Attapulgite sludge slurry to be body material, and Attapulgite sludge slurry is made up of following component by weight percentage: attapulgite clay 15～35% and water 65～85%; (2) sodium is handled: Attapulgite sludge slurry is transported in the stirrer, stirs after adding sodium hydroxide, be transported in the sodium pond ageing 1～7 day through the Attapulgite sludge slurry after stirring; The sodium batching is made up of following component by weight percentage: Attapulgite sludge slurry 95～99.5% and sodium hydroxide 0.5～5%; (3) acidification: Attapulgite sludge slurry after the sodium is transported in the stirrer, stirs after adding concentration and be 98% sulfuric acid, be transported in the acidification pool ageing 1～3 day through the Attapulgite sludge slurry after stirring; The acidifying batching is made up of following component by weight percentage: Attapulgite sludge slurry 92～99.5% after the sodium and concentration are 98% sulfuric acid 0.5～8%; (4) washing and sieve decon: the slurry of the Attapulgite sludge after the acidifying is transported in the settling tank, soaks again, dash with air pump and turn over, the sieve decon, post precipitation is emitted immersion water, and the slurry transportation of post precipitation is arrived in the finished product pond, and the mud of post precipitation is paste attapulgite clay; The washing batching is made up of following component by weight percentage: Attapulgite sludge slurry 25～65% and water 35～75% after the acidifying; Paste attapulgite clay is made up of following component by weight percentage: attapulgite clay 5～40% and water 60～95%.
The pH value of the immersion water of emitting is neutral meta-acid, is the subsidiary material that are used to produce other products, does not have environmental pollution.
Behind the processing of Attapulgite sludge slurry process sodium, acidification, washing and the sieve decon, paste attapulgite clay becomes a kind of thixotropy and the special good natural magnesium aluminium silicate gel of gumminess, it is neutral that the pH value is, and the viscosity of attapulgite clay, expansion capacity, colloid index, whiteness, specific surface area, absorption property, suspensibility and soil removability all are greatly improved.
The present invention is applicable to the production paste attapulgite clay.
