Basic knowledge application of talc calcium carbonate

2020-07-10 13:58:11

1. Talc calcium carbonate are used for filling. The main purposes are: 1. Increase dimensional stability (that is, reduce shrinkage), 2. Increase the stiffness of the material, 3. Increase the heat resistance of the material, 4. , Reduce material cost other aspects, but also have its shortcomings: 1. Density increases, 2. Poor use, impact toughness decreases, 3. Material gloss decreases. Talc manufacturer


2. Talcum powder has the same particle size distinction as calcium carbonate, generally 300 mesh, 600 mesh, 800 mesh, 1250 mesh 2500 mesh, of course, there are finer ones, generally used in plastics, 800 mesh 1250 can be selected For these two, this can make the performance/price ratio cost-effective.

The price of talcum powder fluctuates. Generally speaking, it is a big problem to set the price according to the number of meshes. For example, the general price of 800 mesh is between 800 950 yuan, the price of 1250 mesh is between 1000 1280 yuan. between. The price is too high too low is normal.

About the difference between talcum powder calcium carbonate:

1. The shape of talcum powder is flake, so it has higher rigidity, dimensional stability heat-resistant temperature, the reinforcement effect is good.

2. Calcium carbonate is generally granular, so its stiffness other aspects are as good as talc, but its price is lower, its whiteness is high, it has little effect on plastic impact toughness.

3. Calcium carbonate can generally be divided into light calcium carbonate heavy calcium carbonate, but talc powder does have this distinction, talc powder is ground natural minerals.

4. Talc has a nucleation effect on polypropylene, while calcium carbonate has no obvious effect in this respect.
