1. The positive modification of calcium carbonate
The universal modification effect in the positive modification of calcium carbonate includes
1) to increase the compound compound The rigidity of the material;
2) Improve the size stability of the composite material;
3) Improve the heat resistance of the composite material and improve the tear resistance of the film.
Special modification performance includes
1) The effect of stretching and impact performance, 2) the effect of smoke during combustion, 3) resistance adhesion,
4) Increasing thermal conductivity, 5) increase liquidity, 6) replace part of some white pigments,
7) Increasing breathable performance, 8) Promoting product degradation performance, 9) a nuclear role,
] 10) Reduce the water absorption of PA plastic, 11) Improve the surface performance, 12) Promoting foaming et al.
In addition, calcium carbonate also has environmental protection effects such as oil resources and giving environmental protection performance.
2. Negative modification of calcium carbonate
The negative modification of calcium carbonate includes:
1) increase the density of composite materials, 2) reduce the luster of the composite material, 3) Reduce the transparency of composite materials,
4) Reduce the elongation of the composite material, 5) In most cases, reduce the stretching intensity and impact strength of the composite material,
6) Increasing the phenomenon of stress -whitening, 7) accelerate the aging of products, 8) reduce the connection intensity between materials.
