HS Code 28365000 Precipitated Calcium Carbonate Powder With
PCC for paper/precipitated calcium carbonate has the same chemical
formula as other types of calcium carbonate, such as limestone,
marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can
arrange themselves in three different ways, to form three different
calcium carbonate minerals. The most common arrangement for both
precipitated and ground calcium carbonates is the hexagonal form
known as calcite. A number of different calcite crystal forms are
possible: scalenohedral, rhombohedral and prismatic. Less common is
aragonite, which has a discrete or clustered needle orthorhombic
crystal structure. Rare and generally unstable is the vaterite
calcium carbonate mineral.
Applications and advantages:
|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|
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
|Plastic||it can increase the volume of plastics, reduce the costs, improve
the size, stability, hardness and tenacity of plastic products.|
|Paperpulp material||it can fully make use of its high whiteness, affinity to water and
shock intensity, low cost widely using .|
|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.|
|Test item(PCC in 1250mesh)||Standards||Result|
|Oil-absorbed value (gDOP/100gCaCO3 )||≤100||85|
|residue on 45μm testing sieve(%)||≤0.4||0.1|
|water absorption value||≤20||18.1|
