  • What are the distinction that the French chalk that says normally and light calcic pink weigh calcic pink and application each

    French chalk and calcium carbonate are to use those who do stuff, its purpose basically has: 1, increase dimension stability (contract namely reduce) , 2, increase the stiffness of material, 3, increase the heat-resisting performance of material, 4, reduce a few respects such as cost of material, but also have its drawback: 1, density increases, 2, use bad, concussion tenacity drops, 3, material burnish drops somewhat.

    What there is size like French chalk and calcium carbonate is divisional, it is 300 eye commonly, 600 eye, 800 eye, 1250 eye and 2500 eye, of course, still have finer, and use in commonly plastic inside can choose 800 eye and 1250 eye these two, can make so function / price comparing is highest.

    Use about the distinction of French chalk and calcium carbonate:

    1, french chalk appearance is a shape, have taller stiffness so, dimension stability and heat-resisting temperature, it is good to enhance the result.

    2, calcium carbonate is graininess commonly, so each respects such as its stiffness are inferior to French chalk, but its price is lower, and whiteness is tall, to plastic concussion at the same time tenacity is affected small.

    3, french chalk has nucleate effect to polypropylene, and calcium carbonate is in this side effect is not apparent.

    4, calcium carbonate can be divided commonly weigh qualitative calcium carbonate to pledge calcium carbonate is mixed gently, and French chalk is divisional without this, french chalk comes out from the crocus in crude mineral products.
