plastics additives is solution plastics products production in issues most solution/scheme 之一. plastics additives not only can improve/increase plastics formed product quality, also can manufacturing most large degree reduce production cost, from 而赚取 more more profit. to plastics additives, can overlook CaCO3石灰石 powder. let understanding lower this type of additives.

plastics industrial in additives is what ——石灰石 powder CaCO3?

CaCO3, Scientific Names carbon acid 钙, is 自然界 in non Common combined material. it in many material structure material （海洋生 material housing/shell / hard housing/shell, 如牡蛎, 蜗牛, 珍珠, 蜗牛, housing/shell ）以 and many 质形态 in. CaCO3 most Common and is 人知 源 is 石灰岩矿石, this is types usually in or water 附近形 formed 沉积岩. this is this type of plastics additives main/primary 源. in addition, also can in many other material and in to carbon acid 钙, 例如白垩, large or large 理石.

CaCO3 plastics additives is what?

large more industrial upper use carbon acid 钙, especially is as is plastics industrial additives, main/primary is from 采石场（ large 理石采石场） or 落基山脉（石灰岩山）开采. EuP expert according to assessment Vietnam 石灰石 源 quality selection most 佳 源. from formed is color masterbatch production most raw materials 源. remove 开采天然石灰石资源 outer, also has types carbon acid 钙, it is oxidation carbon, water and 生石灰 (CaO) reaction formed 人工产 material.

CaCO3 一 property 质

未经处理 天然石灰石 powder white white, odor, types type: understanding 石, and 球霰石, its in understanding is most stability more type material. CaCO3 is types alkali property combined material, and acid property solvent liquid strong/high reaction, formed CO2. in high temperature lower, carbon acid separation understanding formed oxidation 钙, 俗称石灰.

CaCO3 how to classification?

经 开采 and 预处理 rear, CaCO3 separation is 2 types type type: fine carbon acid 钙（Ground calcium carbonate - GCC） and carbon acid 钙（precipitated calcium carbonate - PCC）. in market upper, fine carbon acid 钙GCC is most important filler, by widely used in many industry, especially is most important plastics additives combined material. fine CaCO3 is through will 生石灰石破碎 formed powder pellets, rear according to its large small classification production.

meanwhile, PCC沉淀 method CaCO3常 used as strong/high additives, strong/high filler and adjustment impact resistant property. this type of CaCO3 production process ratio fine CaCO3 production complex more, main/primary 包括3 steps: raw materials in high temperature （1000oC） lower 钙化, 生石灰 water combined formed 乳石灰. most rear, 乳石灰 will through CO2 传导 and and drying versus combined by carbon 化, production most product, drying 形式沉淀 CaCO3.

石灰石 powder as is plastics additives has what function?

因 is manufacturing can adjustment manufacturing process control CaCO3 形状 and dimensions, PCC provide series technology 先进 效果, this 效果远远 excellent GCC fine CaCO3 and additives. in chemical upper, PCC and GCC formed 几乎完 full versus 似. PCC pure degree more high, is in manufacturing it process in, oxidation silicon and content by remove. most large difference in high large lower large small and 形状. generally 说, CaCO3 in pellets （ in in ） distribution ratio fine CaCO3 in pellets distribution more narrow, from make its tool has more good property and can force.
总 说, CaCO3石 powder in industrial production in by used as plastics additives has below/following several causes:

- CaCO3 tool has 天然 白 degree, therefore use CaCO3 filler plastics products use 漂白, increase or other color agent can to high degree. this is manufacturing 商节省 a large amount of 资金

- CaCO3 is 自然界储 amount 丰富 矿产资源, easy 于开采 and processing, therefore price non 常便宜. manufacturing can a large amount of use carbon acid 钙而不 use cost

- will 石灰石 powder mixed 入原生 plastics in, 不会改变原生 plastics features, therefore in plastics products production in use it 们代替部 separation 投入材 material, will 帮助厂家节省 a large amount of 开支

- in addition, CaCO3 tool has good heat resistant property, rate and suitable for multiple plastics dimensions

- environmental protection, can anti 止蒸发, reduce production temperature degree

- CaCO3 has increase product surface hardness and gloss degree, manufacturing printing more 美观, more more packaging and design

- can and other plastics additives and color agent 舒适 结 combined use

今天, CaCO3 石灰石 powder not only by type development and used as plastics industrial additives, but also also used for many other industry and production, 例如黑 sheet/plate, production, and construction, 农业, and ring 境部门.
