carbonate calcium powder
1.Characteristic
1).Identical grain size ,low oil absorption value.
2).To reduce the cost of products ; to make products have good foamed effect.
3).To enhance hardness,rigidity,size stability ,fire-retardantness,glossiness of products.
4).In rigid PVC products, it can accelerate gelation, enhance cold impact strength, eliminate plate out, and improve surface gloss.
2.manufacture process: burn the limstone or calcite so create the calcium oxide then mix the
water,create the Calcium hydroxide,then through carbonize,dehydrate,dry and smash.
