Calcium silicate yog cov khoom nrov uas xav tau hauv ntau yam haujlwm. Txawm hais tias nyob rau hauv nws daim ntawv dawb huv nws yog cov hmoov, txhua yam khoom lag luam tuaj yeem tsim los ntawm nws, piv txwv li, cov laug cam tsis kam, uas tau siv rau ntsib lub qhov cub thiab qhov cub. Thiab tseem yog cov khoom siv hauv kev tsim khoom noj thiab kev lag luam kws tshuaj.

Khoom

Calcium silicate belongs rau pab pawg ntawm cov tshuaj inorganic. Sab nrauv, nws zoo li hmoov dawb lossis tsis muaj xim. Nws tsis muaj saj thiab tsis hnov tsw, thiab cov khoom tsis yaj hauv dej, thiab yog cov adsorbent zoo - nws tuaj yeem nqus tau cov kua. Nyob rau tib lub sijhawm, nws ntshai qhov cuam tshuam ntawm cov kua qaub muaj zog.

Muaj ntau yam kev hloov pauv ntawm calcium silicate:

• orthosilicates;
• hydrosilicates;
• pyrosilicates;
• cov metasilicates.

Lawv muaj qee qhov sib txawv hauv cov tshuaj lom neeg, txawm hais tias peb lub ntsiab tseem ceeb tsis tu ncua ntawm cov khoom tseem ceeb ntawm cov sib xyaw: Ca, Si, O.

Qee qhov yam ntxwv tseem ceeb ntawm cov khoom siv yog lub peev xwm ua kom sov, tsis muaj kev tiv thaiv thiab muaj peev xwm tiv taus kev cuam tshuam ncaj qha rau nplaim taws. Refractory rwb thaiv tsev board ua los ntawm calcium silicate muaj cov khoom hauv qab no:

• tuaj yeem tiv taus qhov kub txog 1100 degrees, lub sijhawm nyob ntawm qhov tuab ntawm phaj, qhov nruab nrab, cov khoom zoo li no tuaj yeem tuav cov nplaim taws rov qab los ntawm 30 feeb mus rau 2 teev;
• tsis tso cov pa luam yeeb, ua rau nws muaj peev xwm khiav tawm thaum muaj hluav taws;
• cov khoom tiv taus hluav taws yog lub teeb heev, uas yooj yim rau kev teeb tsa thiab ua haujlwm nrog lawv, thiab qhov hnyav qis tsis ua rau cov phab ntsa hnyav dua thiab tshem tawm qhov xav tau los teeb tsa lathing ntxiv;
• pwm thiab lwm hom kab mob tsis tsim rau ntawm nplooj ntawv, nas, kab thiab lwm yam kab tsuag yuav tsis txaus siab rau lawv.

Cov rwb thaiv tsev tiv thaiv cua sov tau siv rau qhov ua kom tiav qhov cub thiab qhov chaw hauv qhov chaw uas muaj qhov phom sij txaus ntshai uas cuam tshuam nrog hluav taws. Cov khoom siv zam kev kis hluav taws. Cov khoom muaj nyob hauv ntau qhov sib txawv thiab tuab, yog li koj tuaj yeem xaiv qhov kev xaiv zoo tshaj plaws. Cov tsis nyiam tshaj plaws: 1080x950x30 mm, 1500x1250x60 mm, 1000x625x40 mm.

Qhov ntev yuav txawv, nws txhua yam nyob ntawm cov nroj tsuag uas tsim cov ntawv.

Nws tsim tawm li cas?

Cov khoom tau txais los ntawm kev sib xyaw hauv chav kuaj, thiab tseem tau txais ib txwm muaj. Muaj cov pob zeb hauv av wollastonite, uas yuav luag dawb huv calcium silicate, tshwj tsis yog qee qhov me me ntawm titanium oxide, manganese thiab hlau oxide. Hauv kev tsim khoom, cov khoom siv tau tsim los ntawm lwm cov khoom ntuj: feldspar, mica, av nplaum.

Nov yog yuav ua li cas thiaj ua tau cov ntawv txheeb

• Silica thiab txiv qaub tau siv ua cov khoom xyaw kom tau txais cov khoom. Cov tshuaj tiv thaiv kab mob tshwm sim nruab nrab ntawm lawv, ua rau tsim cov calcium silicate.
• Lub hauv paus rau pawg thawj coj yog cov khoom siv fiber ntau nrog lub zog siab. Qhov no yog kev txhawb ntxiv.
• Calcium silicate tau siv rau hauv txheej txheej thiab sab laug rau qee lub sijhawm kom crystallize. Hauv chav kawm ntawm cov txheej txheem no, tau ua tiav lub rooj tsav xwm zoo uas tsis muaj qhov hluav taws kub siab.

Cov ntawv ua los ntawm cov khoom siv no muaj cov nplaim du, uas ua rau lawv haum rau txhua yam haujlwm zoo nkauj . Koj tuaj yeem nrawm cov khoom ua ke nrog tus kheej tapping screws, thiab cov pob qij txha tau yooj yim npog nrog mastic. Cov phaj tuaj yeem txiav yam tsis muaj kev siv zog yog tias tsim nyog rau kev teeb tsa.

Cov tshuaj nquag tshaj plaws tau tsim hauv Denmark thiab Lub Tebchaws Yelemees, cov thawj coj yog Skamol thiab Calsitherm . Hauv tebchaws Russia thiab lwm lub tebchaws tseem muaj cov nroj tsuag tsim cov calcium silicate.

Cov khoom lag luam hauv Suav tsis nrov dua vim lawv tus nqi pheej yig, tab sis qhov no muaj kev pheej hmoo ntawm kev ntog ntawm cov khoom tsis zoo.

Cov ntawv thov

Nyob ntawm qhov zoo ntawm cov khoom, muaj ntau txoj hauv kev los siv nws

• Cov laug cam uas siv tau rau lub ntsej muag lub qhov cub thiab lub qhov cub, rau kev kho chav chav rhaub dej kub, ua lub rhaub dej kub ntxiv rau cov cua sov zoo dua qub. Lawv tsim nyog rau cov tsev nyob thiab pej xeem nrog rau cov cuab yeej siv.

• Cov hmoov ntawm silicate yog xav tau hauv kev lag luam khoom noj. Cov tshuaj ntxiv no tau sau lo lus E552. Nws yog siv los tiv thaiv lo thiab clumping ntawm ntau yam khoom lag luam.
• Crystals tuaj yeem yog ib feem ntawm cov tshuaj thiab cov khoom noj ntxiv, nrog rau tshuaj pleev thiab tshuaj pleev ib ce.
• Cov khoom tau txais cov khoom sib ntxiv tau ntxiv rau cov cement, cov xim thiab cov kua roj vanish, primer thiab plaster.
• Silicate kuj yog ib qho ntawm cov khoom siv hauv kev tsim cov plooj (porcelain).
• Hauv kev ua liaj ua teb, cov khoom siv yog siv ua chiv, ua cov khoom siv silicon, uas tsim nyog rau qee cov nroj tsuag.

Ib txwm muaj calcium silicate tau siv nyob qhov twg nws yuav cuam tshuam nrog zaub mov, tshuaj pleev ib ce lossis tshuaj.

Cov tshuaj sib txuas nrog cov tshuaj ntxiv uas txhim kho cov yam ntxwv ua haujlwm tau siv hauv lwm qhov chaw.

Txwv tsis pub siv

Hauv ntau lub tebchaws, calcium silicate tau lees paub tias muaj xwm txheej nyab xeeb. Nws siv nyob rau hauv kev lag luam khoom noj khoom haus raug tso cai, tab sis nyob hauv qhov tsawg thiab ua raws li cov qauv huv thiab kev kis kab mob. Hauv tebchaws Russia, cov khoom no tsis tuaj yeem siv rau kev tsim khoom noj . Qhov no yog vim qhov kev tshawb fawb tsis txaus xav tau los sau cov ntaub ntawv pov thawj thiab txiav txim siab muaj txiaj ntsig zoo txhua hnub. Raws li kev siv calcium silicate rau kev tsim cov khoom siv hauv tsev thiab lwm yam khoom lag luam uas tsis cuam tshuam nrog zaub mov lossis chaw kho mob, tsis muaj kev txwv.
