Abstract
The invention discloses a kind of powdered whiting dry method modification processing technology, comprise the following steps：1) powdered whiting is chosen, being put into drying chamber carries out drying 4-5 hours；2) powdered whiting after drying is put into agitator, the temperature in agitator is increased to 70-90 DEG C；3) agitator is started, is stirred 10-20 minutes, stir speed (S.S.) is 400-500 revs/min, and to addition stearic acid or aluminate coupling agent in agitator；4) powdered whiting cooling, screening are obtained into finished product.Processing technology of the present invention, dry method modification treatment is carried out using stearic acid or aluminate coupling agent to powdered whiting, the characteristics of overcome calcium carbonate itself, becomes a kind of reinforcement and filler material modified；The process is simple, low production cost, easy to operate, suitable large-scale production.
Description
Technical field
The present invention relates to the modified processing technique field of powdered whiting, more particularly to a kind of heavy carbon
Sour calcium dry method modification processing technology.
Background technology
Calcium carbonate raw material is wide, cheap, non-toxic, easy to use, be domestic and international yield and
One of maximum inorganic filler agent of consumption, mainly as plastics, rubber, coating, paint and
The inserts of the industries such as papermaking.But there is hydrophilic oleophobic using the calcium carbonate that common process is manufactured
Surface characteristic, can only play a part of increment and filling.
The content of the invention
The present invention is for above-mentioned calcium carbonate defect problem of the prior art, there is provided a kind of heavy
Calcium carbonate dry method modification processing technology, the processing technology is carried out at dry method modification to powdered whiting
Reason, the characteristics of overcome calcium carbonate itself, becomes a kind of reinforcement and filler material modified；The work
Skill is simple, low production cost, it is easy to operate, be adapted to large-scale production.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of powdered whiting dry method modification processing technology, comprises the following steps：
1) powdered whiting is chosen, being put into drying chamber carries out drying 4-5 hours；
2) powdered whiting after drying is put into agitator, the temperature in agitator is raised
To 70-90 DEG C；
3) agitator is started, is stirred 10-20 minutes, stir speed (S.S.) is 400-500 revs/min,
And to addition stearic acid or aluminate coupling agent in agitator；
4) powdered whiting cooling, screening are obtained into finished product.
Further, the stearic consumption is the 0.8-1.2% of powdered whiting quality.
Further, the stearic consumption is the 1% of powdered whiting quality.
Further, the consumption of the aluminate coupling agent is powdered whiting quality
1.2-1.8%.
Further, the consumption of the aluminate coupling agent is the 1.5% of powdered whiting quality.
Beneficial effects of the present invention：A kind of powdered whiting dry method modification processing technology, the processing
Technique carries out dry method modification treatment using stearic acid or aluminate coupling agent to powdered whiting, gram
The characteristics of taking calcium carbonate itself, becomes a kind of reinforcement and filler material modified；The process is simple,
Low production cost, easy to operate, suitable large-scale production.
