Hnyav calcium carbonate yog ib qho ntawm cov khoom siv hlau tsis yog hlau nrog kev tsim khoom siab thiab kev siv nplai hauv ntiaj teb niaj hnub no.Nws yog dav siv hauv plastics, papermaking, roj hmab, coatings, adhesives, inks, tshuaj txhuam hniav, pub, khoom noj khoom haus additives, thiab lwm yam.

Yuav kom paub qhov txawv ntawm lub teeb calcium carbonate, ntuj carbonates xws li calcite, limestone, marble, chalk, thiab plhaub feem ntau yog siv los ua raw cov ntaub ntawv, thiab cov ntxhia hmoov ua los ntawm cov neeg kho tshuab crushing hu ua hnyav calcium carbonate (xa mus rau hnyav calcium. carbonate).Tam sim no, cov khoom siv raw rau cov hmoov calcium hnyav hauv Suav teb yog tag nrho cov tsim los ntawm lub regional metamorphism thiab thermal contact metamorphism ntawm carbonates.

Hnyav calcium yog ib qho ntawm thawj zaug thiab feem ntau siv fillers hauv kev lag luam roj hmab.Nws tuaj yeem tsis tsuas yog nce qhov ntim ntawm cov khoom, tab sis kuj txuag cov roj hmab kim heev lossis cov roj hmab hluavtaws, ua tiav lub hom phiaj ntawm kev txo nqi.

Lub luag haujlwm tseem ceeb ntawm cov calcium hnyav hauv kev lag luam roj hmab yog:

1, Txhim kho kev ua haujlwm.Hauv cov qauv ntawm cov khoom siv roj hmab, feem ntau yuav tsum tau ntxiv ob peb feem ntawm cov calcium hnyav;Nyob rau hauv lub teeb xim fillers, hnyav calcium muaj zoo dispersibility thiab yuav muab tov nrog roj hmab nyob rau hauv ib tug ratio, los yog lwm yam additives yuav muab sib tov ua ke, ua kom nws yooj yim.

2 、 Txhim kho cov khoom ntawm cov roj hmab vulcanized, ua si lub luag haujlwm txhawb nqa thiab semi reinforcing.Ultrafine thiab micro calcium carbonate puv roj hmab tuaj yeem ua tiav lub zog nthuav dav dua, hnav tsis kam, thiab lub zog tsim kua muag dua li cov roj hmab sulfides ntshiab.Qhov zoo dua cov calcium carbonate, qhov tseem ceeb ntawm kev txhim kho cov roj hmab expansion zog, tsim kua muag lub zog, thiab yooj.

3 、 Hauv kev ua cov roj hmab, nws ua lub luag haujlwm tshwj xeeb.Nyob rau hauv cov roj hmab vulcanized, hnyav calcium tuaj yeem kho qhov hardness, thaum nyob rau hauv kev lag luam roj hmab, qhov hardness feem ntau hloov los ntawm kev hloov cov nyiaj calcium carbonate filling.

Guilin Hongcheng muab ntau yam qauv ntawm kev sib tsoo tshuab cov cuab yeej haum rau kev nplua thiab ultrafine hmoov ua nyob rau hauv Tuam Tshoj hnyav calcium hmoov ua.Ob peb series ntawm cov khoom, nrog rauHC series zoo hmoov sib tsoo tshuab, HCH series ultrafine sib tsoo tshuab, thiab HLM series ntsug sib tsoo tshuab, yog dav nyiam los ntawm hnyav calcium hmoov ua lag luam.
