Tam sim no, cov txheej txheem ntau lawm ntawm hnyav calcium carbonate feem ntau suav nrog txoj kev qhuav thiab txoj kev ntub dej.Txoj kev qhuav feem ntau tsim cov calcium hnyav nrog tsawg dua 2500 mesh.Yog tias cov calcium hnyav uas muaj ntau tshaj 2500 mesh yog tsim, kev sib tsoo ntub dej feem ntau yog siv, thiab kev sib tsoo qhuav yog thawj kauj ruam ntawm kev sib tsoo ntub dej.Kev sib tsoo ntub dej hnyav calcium muaj cov yam ntxwv ntawm kev ua haujlwm zoo fluidity, siab ci ntsa iab thiab cov khoom siv zoo heev, thiab feem ntau yog siv hauv cov khoom yas;Nrog rau qhov nce ntawm fineness, qhov sib piv piv, washability thiab whiteness ntawm latex xim siv rau sab hauv phab ntsa maj mam nce.Yog li ntawd, ntau thiab ntau hnyav calcium manufacturers tau pib tsim cov khoom ntub sib tsoo hnyav calcium los ntawm covqhuav txheej txheem hnyav calcium ua ntau lawm kab.HCMilling (Guilin Hongcheng), ua cov chaw tsim khoom ntawm hnyav calciumsib tsoo zebtshuab, yuav qhia txog kev tsim khoom thiab daim ntawv thov kev sib tsoo hnyav calcium.

1, Kev tsim cov ntub dej sib tsoo hnyav calcium carbonate: ua ntej, kev ncua ntawm kev sib tsoo hnyav calcium hmoov yog muab tso rau hauvhnyav calciumsib tsoo zebrau ntxiv crushing, thiab tom qab ntawd ultra-nplua hnyav calcium carbonate yog npaj tom qab lub cev qhuav dej thiab ziab.Kev tsim cov txheej txheem ntub dej sib tsoo hnyav calcium yog raws li hauv qab no:

(1) Raw ore → puab tsaig tawg → Calcium carbonate Raymond zeb → ntub sib xyaw zeb lossis tshuab stripping (nruab nrab, ntau theem lossis ncig) → ntub dej cais → tshuaj ntsuam → ziab → ua kom → ntim (coated qib hnyav calcium carbonate).Kev faib tawm ntub dej ultrafine ntxiv rau cov txheej txheem ntws, uas tuaj yeem cais cov khoom tsim nyog raws sijhawm thiab txhim kho kev ua haujlwm.Wet ultrafine classification khoom feem ntau suav nrog me me txoj kab uas hla cyclone, kab rov tav kauv classifier thiab disc classifier.Lub slurry tom qab kev faib tawm yog qhov nyias nyias, thiab qee zaum yuav tsum muaj lub tank sedimentation.Cov txheej txheem muaj cov ntsuas kev lag luam zoo, tab sis kev faib tawm yog qhov nyuaj rau kev khiav lag luam.Tam sim no, tsis muaj cov khoom siv ntub dej ultrafine zoo heev.

(2) Raw ore → puab tsaig tawg → Calcium carbonate Raymond zeb → ntub dej nplawm zeb → tshuaj ntsuam → ziab → ua kom → ntim khoom (qib qib hnyav calcium).

(3) Raw ore → puab tsaig tawg →Calcium carbonate Raymond zeb → ntub stirring zeb los yog stripping tshuab (nruab nrab, ntau theem lossis ncig) → kev tshuaj ntsuam (cov ntawv txheej qib hnyav calcium slurry).

2, Qhov zoo ntawm kev sib tsoo hnyav calcium: piv nrog qhuav sib tsoo hnyav calcium, ntub sib tsoo hnyav calcium muaj qee qhov zoo.Feem ntau yog reflected nyob rau hauv cov nram qab no yam:

(1) Particle loj: superfine hnyav calcium uas tsim los ntawm kev sib tsoo ntub dej muaj qhov loj me me, feem ntau ua cov khoom lag luam nrog ntau tshaj 3000 meshes, <2 μ Cov ntsiab lus ntawm m feem ntau tuaj yeem ncav cuag 90%, thaum cov nplej loj ntawm cov khoom qhuav kuj tseem ntxhib, feem ntau ua cov khoom hauv qab 2500 mesh.

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

(3) Granular: Vim qhov sib txawv ntawm ib puag ncig thiab kev ntxhov siab ntawm cov khoom sib tsoo thaum sib tsoo, cov khoom ntub dej sib tsoo hnyav cov khoom siv calcium feem ntau yog kheej kheej lossis quasi-spherical, thaum cov khoom siv qhuav feem ntau yog amorphous nrog cov npoo thiab cov fab.

(4) Moisture: Cov ntub dej superfine hnyav calcium tau dhau los ntawm cov txheej txheem ziab hauv cov txheej txheem tsim khoom, thiab cov dej noo feem ntau tswj tau qis dua 0.3%, tab sis cov dej noo ntawm cov calcium hnyav uas tsim los ntawm txoj kev qhuav tsis tuaj yeem tswj tau, feem ntau ntau dua. 1%.Yog li ntawd, qhov dispersion thiab fluidity ntawm cov ntub dej superfine hnyav calcium thaum lub sij hawm hloov kho cov txheej txheem yog pom tseeb zoo dua cov uas ua los ntawm txoj kev qhuav.

3,Thov lubhnyav calciumsib tsoo zeb rau ntub sib tsoo ntawm hnyav calcium:

(1) Cov xim emulsion: Thaum calcium carbonate yog siv los ua cov khoom siv hauv cov xim latex, nws ua lub luag haujlwm puv thiab muaj qee qhov kev ua haujlwm qhuav, uas tsis yog tsuas yog txo cov nqi ntawm cov xim latex, tab sis kuj ua raws li lub cev pob txha, thiab txhim kho cov txheej txheem. zaj duab xis thickness, hardness, dej tsis kam thiab txhuam tsis kam.Yog li ntawd, kev siv cov calcium hnyav nyob rau hauv lub tsev txheej kev lag luam yog ntau thiab ntau dua.

(2) Permeable membrane: Qhov dispersity thiab particle loj (loj thiab tis) ntawm calcium carbonate hmoov txiav txim siab fluidity ntawm cov hmoov nws tus kheej, thiab tseem cuam tshuam ncaj qha rau kev ceev ceev thiab txheej txheem stability ntawm cov permeable membrane, uas muaj lub luag hauj lwm txiav txim siab nyob rau hauv lub tensile porosity, pore qauv, permeability thiab mechanical zog ntawm permeable membrane.Kev siv cov calcium hnyav uas tsim los ntawm kev sib tsoo ntub dej li "porogen" muaj qis dua cov nqi nqus roj, zoo dua dispersion thiab fluidity, thiab tseem tuaj yeem txo qis cov cab cab, plasticizer, lubricant thiab lwm yam khoom ntxiv.

(3) Xim masterbatch: Xim masterbatch xim yog feem ntau siv txoj hauv kev xim yas tam sim no, uas feem ntau yog tsim los ntawm cov cab kuj, xim thiab cov khoom ntxiv.Ntau cov kev tshawb fawb tau pom tias siv calcium carbonate, wollastonite lossis barium sulfate los hloov qee cov pigments los npaj cov xim masterbatch tuaj yeem txhim kho cov dispersion ntawm pigments thiab txo cov nqi tsim khoom yam tsis muaj kev txo cov xim ntawm cov xim masterbatch.Qee cov kev tshawb fawb tau pom tias cov xim masterbatch tau npaj los ntawm ntub dej sib tsoo calcium bicarbonate es tsis txhob ntawm titanium dioxide, thaum qhov hloov pauv yog 20%, qhov kev ua tau zoo ntawm cov xim tsis hloov, thiab kev ua tau zoo zoo ib yam li cov xim ntshiab, nrog cov xim me me.

Raws li cov neeg tsim khoom ntawm hnyav calciumsib tsoo zebmachine, uaHCQ, HC series loj hnyav calcium Raymond zeb, HLM hnyav calcium coarse hmoov ntsugsib tsoozebthiab lwm yam hnyav calciumsib tsoo zebCov cuab yeej tsim los ntawm HCMilling (Guilin Hongcheng) tau siv dav thiab yeej lub koob npe nrov hauv pem hauv ntej-kawg qhuav qhuav ntawm ntub sib tsoo hnyav calcium.Yog tias koj muaj kev thov rau kev sib tsoo ntub dej ntawm cov calcium hnyav thiab xav tau cov khoom siv hauv pem hauv ntej-kawg qhuav sib tsoo zeb, thov hu rau HCM kom paub meej cov khoom siv.
