Gas silicate blocks, cov yam ntxwv ntawm kev uas yuav nthuav tawm hauv tsab xov xwm, muaj ntau niaj hnub no. Qhov no yog vim qhov tseeb tias lub cellular pob zeb no muaj qhov hnyav thiab zoo heev.
Composition ntawm roj silicate
Hauv kev tsim cov khoom lag luam hais, cov khoom siv zoo Portland cement yog siv, ntawm cov khoom xyaw uas calcium silicate yuav tsum muaj nyob rau hauv ib lub ntim sib npaug li ½ ntawm tag nrho qhov hnyav. Ntawm lwm yam, xuab zeb yog ntxiv rau qhov sib tov, uas muaj quartz (85% lossis ntau dua). Thaum cov av nplaum thiab av nplaum nyob rau hauv cov khoom no yuav tsum tsis txhob ntau tshaj 2%. Boiler txiv qaub kuj ntxiv thaum lub sij hawm tsim cov txheej txheem, quenching ceev uas yog kwv yees li 5-15 feeb, tab sis calcium thiab magnesium oxide nyob rau hauv nws yuav tsum yog kwv yees li 70% los yog ntau tshaj. Cov khoom lag luam kuj suav nrog tus neeg sawv cev tshuab, uas yog ua los ntawm txhuas hmoov. Muaj nyob rau hauv cov blocks thiab kua, nrog rau sulfanol C.
Gas silicate blocks, tus nqi uas yuav nthuav tawm hauv qab no, tuaj yeem ua tau siv lub autoclave lossis tsis muajnws. Thawj txoj kev tsim khoom ua rau nws tuaj yeem tsim cov blocks nrog lub zog ntau dua, lawv cov shrinkage kuj tsis zoo li, uas tau txais txiaj ntsig los ntawm cov neeg siv khoom.
Cov khoom lag luam uas tau tsim los ntawm kev siv lub tshuab autoclave, tab sis tsis dhau mus rau theem ziab, muaj 5 npaug ntau dua qhov shrinkage piv rau cov blocks uas qhuav hauv autoclave, ntxiv rau, lawv tsis muaj lub zog zoo li no, txawm li cas los xij., lawv raug nqi me me.
Cov txheej txheem autoclave ntawm kev tsim khoom yog siv, raws li txoj cai, hauv kev lag luam loj, qhov no yog vim qhov tseeb tias txoj kev no yog kev siv thev naus laus zis thiab suav nrog kev siv nyiaj ntau ntawm lub zog. Blocks nyob rau hauv cov txheej txheem ntau lawm mus txog theem ntawm steaming ntawm 200 0 С, thaum lub siab ncav cuag 1.2 MPa. Cov neeg tsim khoom hloov pauv qhov sib piv ntawm cov khoom sib xyaw ua ke, uas tso cai rau koj hloov cov yam ntxwv ntawm cov khoom. Piv txwv li, nrog kev nce hauv ntim ntawm cov cement, lub zog ntawm qhov thaiv yuav nce ntxiv, tab sis qhov porosity yuav raug txo, uas yuav cuam tshuam rau kev ua haujlwm thermal vim li ntawd, thiab thermal conductivity yuav nce siab heev.
Specifications
Gas silicate blocks, cov yam ntxwv ntawm cov txheej txheem uas zoo dua los xav txog ua ntej kev yuav khoom, muab faib ua hom raws li qhov ceev. Nyob ntawm qhov ntsuas no, cov blocks tuaj yeem ua qauv, cua sov-insulating thiab structural-heat-insulating. Cov khoom tsim qauv yog cov uas muaj qhov ntom ntom qhia los ntawm D700 hom, tab sis tsis tsawg. Cov khoom nosiv nyob rau hauv kev tsim kho ntawm phab ntsa load-bearing nyob rau hauv cov tsev uas nws qhov siab tsis tshaj 3 plag tsev. Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob muaj qhov ntom ntom hauv D500-D700. Cov khoom siv no zoo heev rau kev tsim kho ntawm sab hauv partitions thiab phab ntsa ntawm cov tsev, qhov siab uas tsis pub tshaj 2 plag tsev.
Roj silicate tshav kub-insulating blocks, cov yam ntxwv ntawm cov khoom tseem ceeb uas yuav tsum paub ua ntej siv lawv hauv kev tsim cov phab ntsa, muaj qhov zoo nkauj zoo nkauj, uas qhia tau tias lawv lub zog yog qhov qis tshaj. Lawv qhov ntom ntom yog sib npaug ntawm D400 txwv, lawv siv los ua cov khoom siv uas tuaj yeem txhim kho thermal kev ua tau zoo ntawm cov phab ntsa ua los ntawm cov khoom siv hluav taws xob tsawg dua.
Zoo ntawm thermal conductivity
Raws li cov thermal conductivity, roj silicate muaj cov yam ntxwv zoo heev. Thermal conductivity yog ncaj qha ntsig txog qhov ntom. Yog li, roj hydrate qib D400 lossis qis dua muaj cov thermal conductivity ntawm 0.08-0.10 W / m ° C. Raws li rau cov blocks ntawm D500-D700 hom, qhov taw qhia tau hais los ntawm 0.12 txog 0.18 W / m ° C. Blocks ntawm hom D700 thiab siab dua muaj thermal conductivity nyob rau hauv thaj tsam ntawm 0.18-0.20 W / m ° C.
Frost resistance
Roj silicate blocks, cov yam ntxwv ntawm cov khoom uas koj yuav tsum paub tseeb tias ua ntej kev yuav khoom, kuj muaj qee yam zoo ntawm kev tiv thaiv te, uas nyob ntawm seb muaj pes tsawg tus pores. Yog li, sib txawv blocks ntawmRaws li cov roj silicate muaj peev xwm tiv taus kwv yees li 15-35 cycles ntawm khov thiab thawing. Txawm li cas los xij, kev txhim kho kev lag luam tsis nyob twj ywm, thiab qee lub tuam txhab tau kawm los tsim cov blocks uas muaj peev xwm dhau mus txog li 50, 75 thiab txawm tias 100 zaug, uas yog qhov txaus nyiam heev, zoo li qhov hnyav ntawm cov roj silicate block. Tab sis yog tias koj yuav cov khoom uas tau tsim nyob rau hauv raws li GOST 25485-89, ces thaum tsim ib lub tsev, koj yuav tsum tau tsom mus rau lub Frost tsis kam Performance index D500 hom, sib npaug rau 35 cycles.
Dimensions thiab loj ntawm blocks
Ua ntej koj pib tsim cov phab ntsa los ntawm cov roj silicate blocks, koj yuav tsum paub seb qhov loj npaum li cas cov khoom tuaj yeem muaj. Raws li txoj cai, cov blocks tau nthuav tawm rau kev muag khoom, qhov ntev ntawm qhov sib npaug: 600x200x300, 600x100x300, 500x200x300, 250x400x600, thiab kuj 250x250x600 mm, tab sis qhov no tsis yog ib daim ntawv teev tag nrho.
Qhov loj ntawm qhov thaiv nyob ntawm qhov ceev. Yog li, yog tias lub block muaj hom D700, thiab nws qhov ntev yog nyob rau hauv 600x200x300 mm, ces qhov hnyav ntawm lub block yuav txawv ntawm 20 mus rau 40 kg. Tab sis lub hom ntawm D700 thaiv nrog qhov ntev ntawm 600x100x300 mm muaj qhov hnyav sib npaug li 10-16 kg. Blocks nrog qhov ntom ntawm D500 txog D600 thiab qhov ntev ntawm 600x200x300 mm muaj qhov hnyav ntawm 17 txog 30 kg. Rau qhov ntom ntawm cov pa roj silicate D500-D600 thiab nws qhov loj hauv ib lub thaiv ntawm 600x100x300 mm, qhov hnyav yuav yog 9-13 kg. Nrog rau qhov ceev hauv D400 thiab qhov ntev sib npaug li 600x200x300 mm, qhov hnyav yuav yog 14-21 kg. Gas silicate qib D400 nyob rau hauv qhov ntev ntawm 600x100x300 mm yuav hnyav kwv yees li 5-10 kg.
cov ntsiab lus zooGas silicate thaiv
Thaum koj paub qhov tuab ntawm cov roj silicate thaiv, koj tuaj yeem kawm txog nws lwm yam ntxwv, suav nrog sab zoo thiab tsis zoo. Ntawm qhov zoo, ib qho tuaj yeem tawm qhov hnyav tsis tseem ceeb, nrog rau lub zog, uas yog txaus rau kev tsim kho qis. Tsis tas li ntawd, cov khoom no muaj cov txiaj ntsig zoo ntawm kev txuag hluav taws xob. Lub suab nrov tsis dhau los ntawm cov phab ntsa zoo li no, thiab cov nqi ntawm cov khoom tseem pheej yig. Blocks tsis hlawv. Nws muaj peev xwm ua tiav kev tsim kho siv cov roj silicate blocks raws li cov nplaum tshwj xeeb, uas tso cai rau kom tau txais cov seam ntawm qhov tsawg kawg nkaus thickness.
Neegative qualities
Xav txog qhov tsis zoo ntawm cov roj silicate blocks, peb tuaj yeem hais txog qhov xav tau rau kev kho kom zoo nkauj sab nrauv, uas ua rau kom muaj kev zoo nkauj ntawm phab ntsa. Blocks tsis txaus nyiam thaum cov neeg siv khoom paub txog lawv cov hygroscopic zoo. Thiab ua ntej pib tsim kho, nws yuav tsum tsim kom muaj lub hauv paus ruaj khov.
Price of blocks
Gas silicate blocks, tus nqi uas yuav txawv nyob ntawm qhov loj, tuaj yeem tso nws tus kheej. Lawv qhov hnyav tsis tas yuav siv cov cuab yeej tshwj xeeb. Yog li, yog tias ib lub thaiv muaj qhov loj me hauv 600x100x300 mm, ces nws tus nqi ib chav yuav yog $1.8-1.9.
