Heavy calcium carbonate imwe yeasiri-metallic mineral materials ane yakakwira kugadzirwa uye chiyero chekushandisa munyika nhasi.Inoshandiswa zvakanyanya mumapurasitiki, kugadzira mapepa, rabha, machira, zvinonamira, ingi, mushonga wemazino, chikafu, chekuwedzera chikafu, nezvimwe.

Kuti isiyanise kubva kuchiedza che calcium carbonate, ma natural carbonates akadai se calcite, limestone, marble, choko, uye mateko anowanzo shandiswa sezvinhu zvakabikwa, uye mineral powder inogadzirwa ne mechanical crushing inonzi heavy calcium carbonate (inonzi heavy calcium). carbonate).Parizvino, zvigadzirwa zveheavy calcium poda muChina zvese zvinoumbwa nedunhu metamorphism uye thermal contact metamorphism yecarbonates.

Heavy calcium ndeimwe yekutanga uye inonyanya kushandiswa mafirita muindasitiri yerabha.Iyo haigone chete kuwedzera huwandu hwezvigadzirwa, asi zvakare kuchengetedza inodhura yakasikwa rabha kana synthetic rubber, kuzadzisa chinangwa chekudzikisa mutengo.

Iwo makuru mabasa eheavy calcium muindasitiri yerabha ndeaya:

1. Kuvandudza mashandiro ekugadzirisa.Muhuwandu hwezvigadzirwa zverabha, zvinowanzodiwa kuwedzera zvikamu zvakati wandei zve calcium inorema;Mune akareruka mavara mafirita, inorema calcium ine yakanaka dispersibility uye inogona kusanganiswa nerabha mune chero chiyero, kana zvimwe zvinowedzera zvinogona kusanganiswa pamwechete, zvichiita kuti kusanganisa kuve nyore.

2, Kuvandudza zvimiro zverabha yakasvibiswa, kutamba inosimbisa uye hafu yekusimbisa basa.Ultrafine uye micro calcium carbonate yakazadzwa rabha inogona kuwana yakakwirira yekuwedzera simba, kusakara, uye kubvarura simba kupfuura pure rabha sulfides.Iyo yakanyanya kunaka iyo calcium carbonate particles, inonyanya kukosha kuvandudzwa kwesimba rekuwedzera rabha, simba rekubvarura, uye kushanduka.

3, Mukugadzirisa rabha, inoita basa rakakosha.Mune vulcanized rubber, heavy calcium inogona kugadzirisa kuoma, nepo muindasitiri yerabha, kuoma kunowanzogadziriswa nekushandura huwandu hwe calcium carbonate kuzadza.

Guilin Hongcheng inopa mhando dzakasiyana dzemuchina wekukuya wakakodzera kune yakanaka uye yekupedzisira poda kugadzirisa muChina inorema calcium poda kugadzirisa.Zvinoverengeka zvakatevedzana zvezvigadzirwa, kusanganisiraHC yakatevedzana yakatsetseka poda yekukuya michina, HCH akatevedzana ultrafine kugaya michina,uye HLM yakatevedzana yakatwasuka yekukuya michina, vanofarirwa zvakanyanya neanorema calcium poda kugadzirisa mabhizinesi.
