Tam sim no, txoj kev tsim khoom ntawm cov roj carbonate hnyav carbonate feem ntau suav nrog cov qauv qhuav thiab txheej txheem ntub. Cov txheej txheem qhuav feem ntau ua cov calcium hnyav nrog tsawg dua 2500 mesh. Yog tias cov calcium hnyav nrog ntau dua 2500 mesh yog tsim, kev sib tsoo ntub yog siv, thiab sib tsoo ntub yog thawj kauj ruam ntawm ntub kev sib tsoo. Ntub kev sib tsoo cov calcium hnyav muaj cov yam ntxwv ntawm kev ua yeeb yam zoo nkauj, muaj teeb ci zoo nkauj thiab yog siv hauv cov khoom yas; Nrog rau kev nce ntawm kev nce qib, qhov sib piv sib piv, hamabilability thiab whiteness ntawm cov xim yas siv rau sab hauv phab ntsa maj mam nce. Yog li no, ntau thiab ntau dua calcium tuam ntxhab tau pib tsim kev ntau lawm cov khoom ntub dej sib tsoo cov calcium ntub ntawm covCov txheej txheem qhuav hnyav calcium ua ntau lawm kabCov. HCMILLING (GUILIN Hongcheng), raws li cov chaw tsim khoom calcium hnyavsib tsoo zebTshuab, yuav qhia txog kev tsim khoom thiab kev thov uas ntub kev sib tsoo calcium hnyav.

1, zus tau zus tau cov ntub dej sib tsoo cov calbonate hnyav: ua ntej, qhov kev ncua ntawm qhuav sib tsoo calcium hmoov yog muab tso rau hauvcalcium hnyavsib tsoo zebRau kev sib tsoo ntxiv, thiab tom qab ntawd ultra-nplua hluav taws xob calcium carbonate yog npaj tom qab lub cev qhuav thiab qhuav. Cov txheej txheem ntau lawm ntawm ntub kev sib tsoo cov calcium hnyav li hauv qab no:

(1) cov nqaij nyoos → puab tsaig tawg → calcium carbonate raymond zeb → ntub dej sib xyaw zeb los yog sib zog, ntau txoj kev ncig ua si → kev tshuaj ntsuam → kev kuaj kom → kev kawm → Kev ntsuas → kev kawm → kev mus kuaj → kev ntsuas → kev kawm → Kev ntsuas → kev kuaj xyuas → kev kawm tau → Kev ntsuas → kev kawm → kev kawm → kev mus kuaj → kev ntsuas → kev kawm tau → kev kawm → kev kawm tau → Kev ntsuas → kev kawm → Kev ntsuas → kev ntsuas → kev kuaj kom → kev kawm → kev kawm → kev ua haujlwm → ua kom muaj cov roj carbonate hnyav (coated qib calbium carbonate). Ntub dej ultrafine muab ntxiv rau cov txheej txheem ntws, uas tau raws sij hawm cov khoom lag luam thiab txhim kho kev ua tau zoo. Ntub dej ultrafine cov khoom siv eltrrafine tsuas yog suav nrog cov cheeb tsam me me, muab kauv kab rov tav. Lub slurry tom qab kev faib tawm yog qhov nyias nyias, thiab qee zaum ib lub nkoj ua kom tiav. Cov txheej txheem muaj cov ntsuas kev lag luam zoo, tab sis kev faib tawm yog qhov nyuaj ua haujlwm. Tam sim no, tsis muaj lub tshuab hluav taws xob zoo heev eltrafine.

(2) Cov tshuaj nyoos → puab tsaig tawg → calcium carbonate raymond zeb → Rhuav cov zeb → Sumaring → kom qhuav → ua kom → ua kom → bagging (filler qib calcium hnyav).

(3) cov nqaij nyoos ay → puab tsaig tawg →calcium carbonate raymond zeb → Rhuav cov zeb los yog sib zog, sib quas ntus, ntau theem lossis kev ncig) → kev ntsuam xyuas (daim ntawv txheej (ntawv txheej txheem).

2, Qhov zoo ntawm ntub kev sib tsoo cov calcium hnyav: muab piv nrog cov kab sib tsoo hnyav, ntub sib tsoo cov calcium hnyav muaj qee qhov zoo. Mas cuam tshuam hauv cov hauv qab no:

(1) Qhov loj me me: Cov khoom siv hnyav hnyav ua los ntawm cov khoom sib tsoo ntub dej tau muaj ntau dua 3000 lub ntsiab lus ntawm cov khoom lag luam 90%, thaum lub noob nplej loj ntawm cov khoom qhuav yog ntxhib, feem ntau yog tsim cov khoom lag luam hauv qab 2500 mesh.

(2) Particle loj faib: Qhov loj me faib cov calcium tsim los ntawm cov txheej txheem ntub dej los ntawm cov txheej txheem ntub dej yog nqaim, nrog rau ib leeg lossis faib tawm ib leeg; Txawm li cas los xij, qhov me me faib ntawm cov calcium hnyav uas tsim los ntawm cov qauv qhuav yog qhov dav dav, thiab nws yog nyob rau hauv daim ntawv ntawm ob lossis ntau lub ncov.

(3) Granular: Vim cov kev sib tsoo ib puag ncig thiab kev ntxhov siab ntawm cov khoom sib tsoo yog feem ntau cov khoom ntub dej yog feem ntau amorphous nrog cov npoo thiab cov ces kaum.

(4) noo noo: Cov nplaim ntub dej hnyav tau dhau los ntawm cov txheej txheem kom qhuav hauv qab no 0.3%, tab sis noo noo ntawm cov txheej txheem qhuav tsis tuaj yeem tswj tau, feem ntau ntau dua 1%. Yog li ntawd, qhov dispersion thiab fluidity ntawm cov calfine ntub hnyav calcium thaum lub sijhawm hloov kho tau zoo dua li cov tsim los ntawm cov txheej txheem qhuav.

3,Siv tuscalcium hnyavsib tsoo zeb Txhawm rau ntub kev sib tsoo ntawm cov calcium hnyav:

(1) Emulsion Plain: Thaum cov calcium carbonate yog siv los ua cov pleev xim yas, nws tsis yog txo cov xim looj xwb, tab sis kuj ua raws li lub cev pob txha, thiab kuj ua rau cov Zaj duab xis thickness, hardness, dej tsis kam thiab txhuam tsis kam. Yog li, daim ntawv thov ntawm calcium hnyav hauv lub tsev txheej kev lag luam yog ntau thiab ntau dua.

(2) Permeable membrane: Qhov kev tsis sib haum xeeb thiab kev faib tawm cov hmoov ntau ntxiv, thiab ua kom pom kev ruaj khov ntawm lub cev muaj zog, uas muaj lub luag haujlwm txiav txim siab hauv lub Tensile porosity, pore cov qauv, permeability thiab cov kws kho hluav taws xob ntawm lub ntsej muag permbrane. Kev siv cov roj av hnyav tsim los ntawm kev sib tsoo ntub los ntawm cov nqi sib tsoo "

(3) Xim Masterbatch: xim masterbatch xim yog qhov feem ntau siv cov qauv hauv cov khoom siv yas, uas feem ntau yog tsim cov khoom lag luam yas, xim ntxiv thiab ntxiv. Coob tus ntawm cov kev tshawb fawb tau qhia tias siv calcium carbonate, wollastonate lossis barium fashments tuaj yeem txhim kho cov nqi ntau lawm thiab los hloov cov xim masterbatch. Qee qhov kev tshawb fawb tau pom tias cov xim masterbatch npaj los ntawm ntub kev sib tsoo calcium li 20%, kev ua tau zoo heev li ntawm cov xim ntshiab, nrog cov xim ntshiab.

Raws li cov chaw tsim khoom calcium hnyavsib tsoo zebtshuab, tusHCQ, HC Series loj calcium reaymond zeb, Hlm hnyav calcium coarse hmoov ntsugkev sib tsootuav txhuvthiab lwm yam calcium hnyavsib tsoo zebCov cuab yeej tsim los ntawm HCMILLING (Guilin Hongcheng) tau siv dav dav thiab yeej lub koob npe nrov tau yooj yim qhuav ntawm cov nplaim ntub dej sib tsoo cov calcium ntau. Yog tias koj muaj cov khoom lag luam ntau lawm kom ntub dej sib tsoo ntawm cov calcium hnyav thiab cov ntej kawg sib tsoo cov khoom siv zeb zeb zeb zeb qhuav, thov hu rau HCM kom paub cov ntsiab lus ntawm cov khoom siv.
