1. Nano calcium carbonate features
1. Good liquidity ,easy to stirring when PVC plastify and improving processability, such as contractibility rate, surface flatness and anti-yellowing.
2.Improving surface lustrousness: good mixture with PVC and nice lustrousness. low density and good tear resistance in PVC film.
3.Excellent nano features: surface activity help resolve negatively charged electrons and Positively charged hole in ultraviolet light, excellent activity make easy chemical reaction with oxygen and organism , improving ageing resistance.
4. Mature application: big quantity fillers in PVC soft products .
2.Application
1)Rubber: it can reduce the amount of expensive natural rubber,increase its volume ,reduce costs, After adding calcium carbonate then can be obtain higher strength tensile ,tear strength and abrasion resistance than the pure Rubber vulcanizate
2)Chemical manufacturing materials: it is heat-proof, chemical corrosion-proof,cold-proof, anti-noise, shockproof and easy to process. Therefore it can be used to make doors, dry motar ,ceilings, wallboard,waterpipe,handrail of stairs,floor board and electric wire,etc.
3)Painting& coating: it is as the filling and as the framework, Latex paint more than 30% amount are used in thick paint ,26%-60% amount are used in water-based pain
4)Plastic, it can increase the volume of plastics, reduce the costs, improve the size, stability, hardness and tenacity of plastic products.
5)Paperpulp material: it can fully make use of its high whiteness, affinity to water and shock intensity, low cost widely using .
