Abstract
The invention relates to a production method of geotechnical cloth superfine heavy calcium carbonate. The production method comprises the following steps: crushing stones; smashing; grinding; activating; drying; grading; and collecting and packaging the product. The production method is characterized by comprising the following steps: feeding a calcium carbonate coarse material with the diameter of being less then 1cm; respectively adding 1-3% of sodium carbonate and 1-3% of dodecyl dimethyl benzyl ammonium chloride based on the weight percentage of ground calcium carbonate coarse powder; grinding to 5-10 microns at 85-95 DEG C; adding water to prepare slurry with the solid content of 70-80%; adding 1-5% of a modified based on the weight percentage of ground calcium carbonate coarse powder; pumping the slurry into a wet stirring and grinding machine by virtue of a pump valve; and grinding in a grinding medium to obtain modified calcium carbonate superfine powder with the grain size of 0.1-1 micron. The production method provided by the invention has the advantages of being scientific and reasonable in design, simple in process, safe and reliable, easy to control, convenient to operate, suitable for scaled production, low in production cost and the like.
Description
Technical field
The invention belongs to a kind of production method of calcium carbonate powder.
Background technology
At present, calcium carbonate is widely used in papermaking, plastics, plastics film, chemical fibre, rubber, tackiness agent, sealing agent, daily-use chemical industry, makeup, building materials, coating, paint, ink, putty, sealing wax, putty, carpet veneer is packed, medicine, food is (as chewing gum, chocolate), in feed, its effect has: increase small product size, reduce costs, improve processing characteristics (as adjusting viscosity, rheological property, curability), improve dimensional stability, reinforcement or half reinforcement, improve printing performance, improve physicals (as thermotolerance, extinction, wear resistance, flame retardant resistance, whiteness, glossiness) etc.The technological process of production of water-ground limestone has two kinds.Dry technology for production flow process: the first calcite, Wingdale, chalk, shell etc. that ship from stone quarry of picking, to remove gangue; Then with crusher, coarse breaking is carried out to Wingdale, cover that (pendulum-type) abrasive dust is broken obtains microlith limestone flour again with thunder, finally carry out classification with grading machine to abrasive dust, the powder meeting granularity requirements is put in storage as the packing of product, otherwise returns pulverizing mill abrasive dust again.Wet process technique flow process: first dry method fine powder is made suspension and be placed in grinding machine and pulverize further, just obtained superfine heavy calcium carbonate after dehydration, drying.
Retrieve through Chinese publication, find calcium carbonate application for a patent for invention 53; Do not find the scheme identical with present patent application.
Summary of the invention
The object of the invention is to; A kind of production method of geotextile superfine heavy calcium carbonate is proposed.
The production method of geotextile superfine heavy calcium carbonate of the present invention, comprises stone fragmentation, pulverizing, grinding, screening, activation, drying, classification, and product-collecting is packed, it is characterized in that: calcium carbonate coarse fodder diameter being less than 1 centimetre, send in pulverizing mill, with the weight percent meter of coarse heavy calcium carbonate powder, add 1-3% sodium carbonate respectively, 1-3% dodecyl benzyl dimethyl ammonium chloride, after at 85 ~ 95 DEG C, grinding causes 5-10 micron, add water and be made into the slurry that solid content is 70% ~ 80%, with the weight percent meter of heavy calcium carbonate, add 1-5% and add properties-correcting agent, by pump valve, slurry is squeezed into wet method and stir disintegrating machine, grind in grinding medium, obtain the modified superfine Paris white that obtained particle diameter is 0.1 ~ 1 micron, described auxiliary agent, by weight, by 4--γ-(methacryloxypropyl) propyl trimethoxy silicane 1-3 part, ethylene glycol 3-4 part, Sodium hexametaphosphate 99 3-4 part, vinylformic acid-cationic acrylate multipolymer 3-5 part composition.
