Barium sulphate for grinding modifier
1,barium sulphate for grinding modifier technical index:
Appearance:milky white clear liquid;
2,viscosity:12+2 mpa.S(25℃);
PH:8-9;
Weight:1.014+0.02 g/ml;
Solubility:mixed with water in any proportion.
Application range of barium sulphate for grinding modifiers:
This product is suitable for various inorganic powders,such as heavy calcium carbonate,light calcium carbonate,kaolin clay,silica,talcum powder,carbon black,pigment and other surface grinding powder;
The modified powder is especially suitable for the use of plastic,rubber and other oil-friendly industries.
The value of the oil that was modified with this product fell by 15-20%.
3,barium orosulphate modification agent performance characteristics:
It can meet the requirements of low oil absorption in industries such as plastics and rubber.
Plastic can be used to increase plastic volume,reduce the cost of product,and improve the stability,hardness and toughness of plastic.
It can improve the rheology of plastic mother grain and improve its molding.
For the notched impact strength and notch impact strength of the toughening effect is very obvious,also can improve the plastic bending strength and bending modulus of elasticity,thermal deformation temperature and dimensional stability,at the same time also give plastic thermal hysteresis resistance;
Made of polyethylene(PE)/modified calcium carbonate composite nano-sized microporous breathable membrane,has a special breathable waterproof function,can be used for women's sanitary napkin,baby diapers,sanitary cleaning supplies;
The addition of the modified Luxembourg to polyethylene has a great effect on adding plastic toughness.
In rubber industry,reach the reinforcement,filling,toning,improving the processing technology and products performance,to reduce or partly replace silica gel rate etc.The purpose of the expensive white packing;
Modification of barium sulfate filled in rubber products in great quantities,can increase the volume of products,saving costly natural rubber and synthetic rubber,reduce the cost of rubber products;
It can improve its dispersion in rubber,and greatly improve its performance of rubber.
4,barium sulphate for use and dosage:
1,use the same as the general powder modification methods,can also be used with other surfactants and additives,but can't join at the same time,need to add this product first,then add other components.
Based on the customer's different requirements,the quantity of the powder will be calculated with the powder solid content,and the powder body will be 0.1%to 0.25%.
2,the use of metering pump,5-8 times will be diluted good auxiliary measuring spray surface of run of mine ore in secondary crushing ores by spiral feeding or belt conveyor into grinding host,dry grinding process.
Five,the method of storage:under the condition of 10 to 25℃,avoid light,sealed storage can be up to six months.
