Description
Technical field
The invention belongs to a kind of production method of calcium carbonate powder.
Background technology
At present, calcium carbonate has been widely used in papermaking, plastics, plastic sheeting, chemical fibre, rubber, adhesive, sealant, daily-use chemical industry, cosmetics, building materials, coating, paint, ink, putty, sealing wax, putty, carpet veneer packaging, 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 physical property (as heat resistance, extinction, wearability, anti-flammability, whiteness, glossiness) etc. precipitated calcium carbonate, claim again winnofil, be called for short fine particle calcium carbonate, that the raw material calcinings such as lime stone are generated to lime (main component is calcium oxide) and carbon dioxide, the digestion lime that adds water again generates milk of lime (main component is calcium hydroxide), and then pass into carbon dioxide carbonization milk of lime generation precipitation of calcium carbonate, make finally by dewatering, be dried and pulverizing. or first carry out metathesis reaction with sodium carbonate and calcium chloride and generate precipitation of calcium carbonate, then make through dewatering, be dried and pulverizing. because the settling volume (2.4-2.8mL/g) of precipitated calcium carbonate is larger than the settling volume of powdered whiting (1.1-1.9mL/g), so be referred to as precipitated calcium carbonate. the technological process of production of powdered whiting has two kinds. dry technology for production flow process: calcite that first picking is shipped from stone pit, lime stone, chalk, shell etc., to remove gangue, then with disintegrating machine, lime stone is carried out to coarse crushing, cover the broken microlith limestone flour that obtains of (pendulum-type) abrasive dust with thunder again, finally with grader, abrasive dust is carried out to classification, the powder that meets granularity requirements is put in storage as the packing of product, otherwise returns to flour mill abrasive dust again. wet process technique flow process: first dry method fine powder is made to suspension and be placed in further pulverizing in grinding machine, just make superfine heavy calcium carbonate after dewatering, being dried. the industrial production process of modified active calcium carbonate, by the calcium carbonate powder particle of Monodispersed, carry out the coated processing in liquid phase surface, the nm-class active calcium carbonate particle obtaining is between 25～100nm, specific surface is greater than 25m2/g, particle diameter distribution GSD is 1.57, and oil factor is less than 28g/100gCaCO3, and without agglomeration. the excellent product performance obtaining, can be used as the functional stuffing in high-grade rubber, plastics and vehicle paint base.
Through Chinese publication retrieval, find 53 of calcium carbonate applications for a patent for invention; Do not find the scheme identical with present patent application.
