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

1, Kev tsim cov hmoov calcium carbonate uas ntub dej sib tsoo: ua ntej, kev ncua ntawm cov hmoov calcium uas sib tsoo qhuav raug muab tso rau hauvcov calcium hnyavlub tshuab sib tsoorau kev sib tsoo ntxiv, thiab tom qab ntawd cov calcium carbonate hnyav heev yog npaj tom qab dehydration thiab ziab. Cov txheej txheem ntau lawm ntawm kev sib tsoo ntub calcium hnyav yog raws li nram no:

(1) Cov hlau tsis huv → tawg lub puab tsaig → Raymond zeb calcium carbonate → Lub tshuab sib tov ntub lossis lub tshuab stripping (tsis tu ncua, ntau theem lossis ncig) → Lub tshuab cais ntub → kev tshuaj ntsuam → kev ziab → kev ua kom qhuav → kev ntim khoom (qib calcium carbonate hnyav). Kev faib tawm ntub ultrafine ntxiv rau hauv cov txheej txheem, uas tuaj yeem cais cov khoom tsim nyog raws sijhawm thiab txhim kho kev ua haujlwm. Cov khoom siv faib tawm ntub ultrafine feem ntau suav nrog lub voj voog me me, lub tshuab faib tawm kab rov tav thiab lub tshuab faib tawm disc. Cov slurry tom qab kev faib tawm yog nyias nyias, thiab qee zaum xav tau lub tank sedimentation. Cov txheej txheem muaj cov cim qhia kev lag luam zoo, tab sis kev faib tawm nyuaj rau kev ua haujlwm. Tam sim no, tsis muaj cov khoom siv faib tawm ntub ultrafine zoo heev.

(2) Cov hlau tsis huv → tawg lub puab tsaig → Raymond zeb calcium carbonate → lub tshuab sib tov ntub → kev tshuaj ntsuam → kev ziab → kev ua kom muaj zog → kev ntim hnab (cov calcium hnyav qib sau).

(3) Cov hlau tsis huv → tawg lub puab tsaig →Raymond zeb calcium carbonate → lub tshuab sib tov ntub lossis lub tshuab stripping (sib xyaw, ntau theem lossis kev ncig) → kev tshuaj ntsuam (cov calcium slurry hnyav uas siv daim ntawv txheej).

2. Cov txiaj ntsig ntawm kev sib tsoo ntub calcium hnyav: piv rau kev sib tsoo qhuav calcium hnyav, kev sib tsoo ntub calcium hnyav muaj qee qhov zoo. Feem ntau pom tseeb hauv cov hauv qab no:

(1) Qhov loj me ntawm cov khoom me me: cov calcium hnyav superfine uas tsim los ntawm kev sib tsoo ntub muaj qhov loj me ntawm cov khoom me me, feem ntau yog tsim cov khoom nrog ntau dua 3000 meshes, <2 μ Cov ntsiab lus ntawm m feem ntau tuaj yeem ncav cuag 90%, thaum cov noob loj ntawm cov khoom qhuav yog qhov ntxhib, feem ntau yog tsim cov khoom hauv qab 2500 mesh.

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

(3) Granular: Vim yog qhov sib txawv ntawm qhov chaw sib tsoo thiab hom kev ntxhov siab ntawm cov khoom me me thaum lub sijhawm sib tsoo, cov khoom me me ntawm cov khoom siv calcium hnyav sib tsoo ntub feem ntau yog spherical lossis quasi-spherical, thaum cov khoom qhuav feem ntau yog amorphous nrog cov npoo thiab ces kaum pom tseeb.

(4) Dej noo: Cov calcium uas ntub dej superfine hnyav tau dhau los ntawm cov txheej txheem ziab hauv cov txheej txheem ntau lawm, 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 kev tawg thiab kev ntws ntawm cov calcium hnyav superfine ntub dej thaum lub sijhawm hloov kho yog qhov zoo dua li cov uas tsim los ntawm txoj kev qhuav.

3,Siv covcov calcium hnyavlub tshuab sib tsoo rau kev sib tsoo ntub ntawm cov calcium hnyav:

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

(2) Daim nyias nyias uas nkag tau: Qhov kev sib kis thiab qhov loj ntawm cov khoom me me (qhov loj thiab kev faib tawm) ntawm cov hmoov calcium carbonate txiav txim siab qhov fluidity ntawm cov hmoov nws tus kheej, thiab kuj cuam tshuam ncaj qha rau qhov ceev ntawm kev tsim khoom thiab kev ruaj khov ntawm daim nyias nyias uas nkag tau, uas muaj lub luag haujlwm txiav txim siab hauv qhov porosity tensile, pore qauv, permeability thiab cov khoom siv kho tshuab ntawm daim nyias nyias uas nkag tau. Kev siv cov calcium hnyav uas tsim los ntawm kev sib tsoo ntub dej ua "porogen" muaj qhov nqus roj tsawg dua, kev sib kis zoo dua thiab kev ntws zoo dua, thiab tseem tuaj yeem txo qhov ntau ntawm cov khoom siv thauj khoom, cov khoom siv yas, cov roj nplua nyeem thiab lwm yam khoom ntxiv.

(3) Xim Masterbatch: Xim Masterbatch xim yog txoj kev siv ntau tshaj plaws hauv kev pleev xim yas tam sim no, uas feem ntau yog ua los ntawm cov khoom siv thauj khoom, cov xim thiab cov khoom ntxiv. Muaj ntau txoj kev tshawb fawb tau qhia tias kev siv calcium carbonate, wollastonite lossis barium sulfate los hloov qee cov xim los npaj xim masterbatch tuaj yeem txhim kho kev sib kis ntawm cov xim thiab txo cov nqi tsim khoom yam tsis txo qhov kev ua tau zoo ntawm cov xim masterbatch. Qee txoj kev tshawb fawb tau qhia tias cov xim masterbatch npaj los ntawm kev sib tsoo ntub calcium bicarbonate hloov titanium dioxide, thaum tus nqi hloov pauv yog 20%, qhov kev ua tau zoo ntawm cov xim tseem tsis hloov pauv, thiab qhov kev ua tau zoo zoo ib yam li cov xim ntshiab, nrog qhov sib txawv me me ntawm xim.

Raws li tus neeg tsim khoom ntawm cov calcium hnyavlub tshuab sib tsootshuab, lubHCQ, HC series loj hnyav calcium Raymond zeb, HLM hnyav calcium coarse hmoov ntsugkev sib tsoolub zebthiab lwm yam cov calcium hnyavlub tshuab sib tsooCov khoom siv uas tsim los ntawm HCMilling (Guilin Hongcheng) tau siv dav thiab tau txais lub koob npe zoo hauv kev tsim cov calcium hnyav sib tsoo ntub. Yog tias koj muaj kev xav tau ntau lawm rau kev sib tsoo ntub ntawm calcium hnyav thiab xav tau cov khoom siv sib tsoo qhuav, thov hu rau HCM kom paub meej ntxiv txog cov khoom siv.
