碳酸鈣(gai)廠家(jia)小編帶您一起了解重質碳酸鈣是什么。重(zhong)質碳酸鈣是以方解石、白堊、大(da)理石等礦石為原料，經(jing)機械破(po)碎而成的碳酸鈣粉(fen)體材料。它具有原料來源廣(guang)泛(fan)、白度高、吸油(you)值低、適用性好、價(jia)格(ge)低廉的特點。是目前應用比較廣(guang)泛(fan)的無機非金屬(shu)礦物粉(fen)體。

1.重質碳酸(suan)鈣性能(neng)特點:

雖然(ran)重質(zhi)(zhi)(zhi)碳(tan)(tan)酸(suan)(suan)(suan)鈣主要化學成(cheng)分與輕質(zhi)(zhi)(zhi)碳(tan)(tan)酸(suan)(suan)(suan)鈣相同(tong),但(dan)是,與輕質(zhi)(zhi)(zhi)碳(tan)(tan)酸(suan)(suan)(suan)鈣相比,重質(zhi)(zhi)(zhi)碳(tan)(tan)酸(suan)(suan)(suan)鈣具有堆積(ji)(ji)密度(g/cm3)大、沉(chen)降體積(ji)(ji)(mL/g)小、比表面積(ji)(ji)(m2/g)小、吸(xi)油值(mL/g)小等(deng)特點。此外(wai)，重質(zhi)(zhi)(zhi)碳(tan)(tan)酸(suan)(suan)(suan)鈣的聚集程(cheng)(cheng)度小于輕質(zhi)(zhi)(zhi)碳(tan)(tan)酸(suan)(suan)(suan)鈣(輕質(zhi)(zhi)(zhi)碳(tan)(tan)酸(suan)(suan)(suan)鈣的一(yi)次(ci)粒(li)(li)徑較小，聚集程(cheng)(cheng)度較大)。水(shui)溶液的酸(suan)(suan)(suan)堿度：輕質(zhi)(zhi)(zhi)碳(tan)(tan)酸(suan)(suan)(suan)鈣為(wei)9-10；重鈣(GCC)為(wei)8~9。在(zai)(zai)研磨碳(tan)(tan)酸(suan)(suan)(suan)鈣的粉碎過(guo)程(cheng)(cheng)中，雖然(ran)能在(zai)(zai)一(yi)定程(cheng)(cheng)度上影(ying)響顆(ke)粒(li)(li)形(xing)狀，但(dan)不能像輕質(zhi)(zhi)(zhi)碳(tan)(tan)酸(suan)(suan)(suan)鈣那樣通(tong)過(guo)碳(tan)(tan)化過(guo)程(cheng)(cheng)控制顆(ke)粒(li)(li)晶型，生產(chan)(chan)出不同(tong)晶型的產(chan)(chan)品。
