Description
Technical field
The utility model relates to a kind of calcium carbonate granule surface modification device.
Background technology
According to the difference of production method, can be powdered whiting, precipitated calcium carbonate, colloid calcium carbonate and crystal calcium carbonate with divided calcium carbonate.Colloid calcium carbonate claims again modified calcium carbonate, surface treatment calcium carbonate, calcene or calcene, is called for short the calcium of living.Calcium carbonate is precipitated calcium carbonate or coarse whiting calcium carbonate are carried out surface modification and to make with surface modifier.Because the calcium carbonate after the surface modifier modification generally all has strengthening action, i.e. so-called " activity " is so all call activated Calcium carbonate to modified calcium carbonate traditionally.
The activation modification treatment method of calcium carbonate can be divided into dry activation modification and wet-process activation modification.Generally the dry activation modification can be adopted to the calcium carbonate of common fillers level, wet-treating need to be adopted to ultra-fine, nanoscale and tailored version calcium carbonate.The dry activation modification is that the calcium carbonate finished product is put into the high-speed kneading machine, drops into surface conditioning agent after the rotation again and carries out the surface active modification.The dry activation modification is simple, is applicable to various organic surface modifying agent, particularly non-water-soluble various surface modifier.
Publication number is that the utility model of CN202219165U discloses a kind of nano calcium carbonate activation modification reactor, comprises stirring motor, reaction kettle body, agitating device; Stirring motor drives agitating device Stirring in reaction kettle body; Described reaction kettle body top is provided with charging aperture, and the reaction kettle body bottom is provided with discharge gate, and described reaction kettle body sidewall is the double-decker of a hollow, and the reaction kettle body inside sidewalls is provided with more than one baffle plate, and described baffle plate is evenly arranged around reaction kettle body; Also be provided with automatic exhaust steam valve on the reaction kettle body; Described agitating device comprises shaft, the above paddle of one deck; The upper end of shaft is connected with the power transmission shaft of stirring motor, and paddle is socketed on the shaft, and order is vertical with shaft.Only have an agitating device to stir in reactor, react insufficient, modified effect is poor.
