Kev siv calcium carbonate hauv cov xim yog dab tsi?

Calcium carbonate yog cov hmoov tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis ua rau khaus dawb thiab yog ib qho ntawm ntau yam inorganic fillers. Calcium carbonate yog nruab nrabral, ntau insoluble hauv dej thiab soluble hauv acid. Raws li cov txheej txheem ntau lawm calcium carbonate, calcium carbonate tuaj yeem muab faib ua cov calcium carbonate hnyav thiab cov pa roj carbon monoxide.

Calcium acid, colloidal calcium carbonate thiab crystalline calcium carbonate. Calcium carbonate yog ib yam khoom siv hauv ntiaj teb. Nws muaj nyob rau hauv cov pob zeb xws li vermiculite, calcite, chalk, limestone, marble, travertine, thiab lwm yam. Nws kuj yog cov khoom tseem ceeb ntawm cov pob txha tsiaj lossis cov plhaub. Calcium carbonate yog cov khoom siv hauv tsev tseem ceeb thiab siv dav hauv kev lag luam.

Kev siv calcium carbonate hauv cov xim latex

1. Lub luag haujlwm ntawm hnyav calcium

• Raws li lub cev pigment, nws muaj cov nyhuv ua kom zoo, sib xws, thiab dawb.
• Nws muaj ib tug tej yam qhuav nkaum hwj chim, thiab noobrally siv cov khoom zoo heev. Thaum qhov loj me me nyob ze rau qhov loj me ntawm titanium dioxide, cov nyhuv npog ntawm titanium dioxide tuaj yeem txhim kho.
• Nws tuaj yeem txhim kho lub zog, dej tsis kam, dryness thiab txhuam tsis kam ntawm cov duab thaij duab.
• Txhim kho xim tuav tseg.
• Txo tus nqi, kev siv yog 10% ~ 50%. Disadvantages: siab ceev, yooj yim rau precipitate, tus nqi ntawm kev siv yuav tsum tsis txhob loj heev.

 2. Lub luag haujlwm ntawm lub teeb calcium

• Raws li lub cev pigment, nws muaj cov nyhuv puv, zoo, thiab ua kom cov xim dawb.
• Nws muaj lub zog zais cia qhuav.
• Qhov ntom yog me me, qhov tshwj xeeb ntawm qhov chaw yog qhov loj, thiab nws muaj qee yam khoom raug tshem tawm, thiab ua lub luag haujlwm ntawm kev tiv thaiv kev daws teeb meem.
• Txo cov nqi.
• Ua kom muaj kev xav. Disadvantages: yooj yim rau blaze, tsam plab, thickening, tus nqi ntawm kev siv yuav tsum tsis txhob loj heev, tsis tuaj yeem siv rau sab nrauv phab ntsa painting.

Kev siv calcium carbonate hauv hmoov txheej

• (1) Nws tuaj yeem siv los ua cov khoom ntim rau cov khoom siv gloss siab.
• (2) Semi-gloss txheej cov khoom tuaj yeem generally yuav ncaj qha ntxiv nrog calcium carbonate yam tsis muaj qhov sib ntxiv ntawm matting tus neeg saib xyuas, txuag nqi.
• (3) Nws yog xim dawb inorganic uas tuaj yeem siv ua ke nrog titanium dioxide los txo cov nqi.
• (4) Piv nrog rau lwm cov fillers, calcium carbonate yog qhov zoo tshaj plaws rau cov khoom siv hauv ib puag ncig uas xav tau cov hlau hnyav tsawg, xws li cov menyuam yaus cov khoom ua si thiab cov menyuam yaus.
• (5) Nws tuaj yeem txhim kho cov hmoov nplej thiab tshuaj tsuag thaj tsam ntawm cov xim, tshwj xeeb tshaj yog nyob rau hauv cov hmoov sib xyaw.
•  (6) Yog tias yuav tsum muaj huab cua tiv thaiv sab nraum zoov, nws tsis tuaj yeem siv los ua cov khoom ntim.
•  (7) Vim nws cov roj nqus dej siab, nws yooj yim ua rau cov txiv kab ntxwv tev ntawm cov xim pleev xim rau saum npoo. Lub sijhawm no, me ntsis hydrogenated castor roj tuaj yeem ntxiv rau cov khoom siv hauv paus.
•  (8) Nws ua raws li lub cev pob txha los ua kom cov tuab ntawm cov xim pleev xim thiab txhim kho cov hnav tsis kam thiab ua haujlwm ntev ntawm cov txheej.

Kev siv cov calcium carbonate hauv cov ntoo

• (1) Cov khoom ntim rau xim primer kom txo nqi.
• (2) Ua kom cov yeeb yaj kiab muaj zog thiab hnav tsis kam.
• (3) Lub teeb calcium muaj cov nyhuv thickening me ntsis, hloov tau yooj yim, thiab zoo tiv thaiv sedimentation.
• (4) Cov calcium hnyav txo cov xuab zeb hauv cov yeeb yaj kiab xim, thiab nws yooj yim los nag hauv lub tank, yog li nws yuav tsum tau ua tib zoo saib xyuas kom ntxiv dag zog rau cov cuab yeej los tiv thaiv kev poob.
• (5) Txhim kho gloss, dryness thiab whitening ntawm cov xim zaj duab xis.
• (6) Nws yuav tsum tsis txhob siv ua ke nrog alkali-resistant pigments thiab fillers.

Kev siv cov calcium carbonate hauv tsheb xim

 Ultra-fine calcium carbonate nrog particle loj tsawg dua 80nm yog siv los tiv thaiv pob zeb txheej thiab topcoat ntawm lub tsheb chassis vim nws zoo thixotropy. Kev ua lag luam muaj peev xwm yog 7000 ~ 8000t / a, thiab tus nqi hauv kev lag luam thoob ntiaj teb yog siab li 1100 ~ 1200 USD / t. .

Kev siv calcium carbonate hauv tus cwj mem

Ultrafine calcium carbonate yog siv nyob rau hauv inks, exhibits zoo heev dispersibility, pob tshab, zoo heev gloss thiab nkaum lub hwj chim, thiab zoo heev ink adsorption thiab ziab cov khoom, uas yuav tsum tau activated los ua spherical los yog cuboid muaju.
