Cov khoom siv hauv tsev tau pom niaj hnub no muaj ntau yam sib txawv, thiab qee zaum nws nyuaj rau cov tsis yog kws tshaj lij kom nkag siab lawv cov yam ntxwv. Ib qho piv txwv zoo yog qhov tsis meej pem ntawm cov roj silicate thiab cov qhob aerated, uas muaj cov yam ntxwv zoo sib xws. Tab sis qhov zoo sib xws no tsis muaj txoj hauv kev txhais tau tias yog tus kheej.

Lub ntsiab lus ntawm qhov teeb meem yog dab tsi?

Cov peev txheej siv hluav taws xob thiab cov cua sov muab los ntawm cov kav dej cua sov tseem ceeb tau nce ntau dua los ntawm ib xyoos dhau ib xyoos. Yog li ntawd, qhov kev thov rau cov ntaub ntawv tsim kho tau nce ntxiv, uas ua tib zoo txwv kom sov. Cov txiaj ntsig zoo tshaj plaws tau ua tiav thaum siv cov cua sov-insulating hom qhob. Kev nkag siab yuam kev tshwm sim vim tsis zoo ib yam thiab thaj chaw zoo ib yam ntawm kev siv. Qee zaum txawm tias cov kws tsim kev paub tsis tuaj yeem txiav txim siab qhov sib txawv ntawm cov roj silicate thiab cov qhob aerated. Cov tuam txhab tsim khoom ib leeg tau ntxiv rau qhov kev kub ntxhov los ntawm kev sau npe lawv cov khoom.

Txoj kev npaj

Txhawm rau nkag siab txog cov yam ntxwv tshwj xeeb ntawm cov ntaub ntawv, koj yuav tsum nrhiav paub ua ntej tias lawv tsim los li cas. Aerated qhob yog ua los ntawm Portland cement lossis lwm cov cement, uas ntxiv cov xuab zeb thiab txiv qaub. Tab sis cov roj silicate koom nrog pab pawg ntawm cov xov tooj ntawm tes ntawm silicate xwm. Nws yog tsim los ntawm kev sib xyaw ua ke ntawm cov xuab zeb nrog txiv qaub (64 thiab 24%, feem). Tag nrho cov seem yog los ntawm cov tshuaj ntxiv thiab dej.

Cov yam ntxwv cua sov ntawm cov aerated qhob thaiv yog tsim los vim cov qauv ntxeem tau . Nws muaj peev xwm tsim nws hauv kev tsim khoom siv qhov o ntawm cov sib xyaw yooj yim vim yog kev qhia txog cov tshuaj uas tsim cov pores. Cov kab noj hniav ntawm cov khoom tiav yog npuas nrog ntu sab nrauv ntawm 0, 1–0, 3 cm. Cov kab noj hniav no suav txog 70 txog 90% ntawm tag nrho cov ntim ntawm cov khoom. Yog tias kev tsim qauv tau ua tiav raws li txhua txoj cai, cov cell uas muaj cov cua tau tawg ua ib yam.

Ib qho pob zeb yuav tsum ua kom tawv. Kev kho cua sov nrog cov pa pab kom ntxiv dag zog rau cov pa roj silicate. Txhawm rau ua qhov no, cov khoom ua haujlwm tau muab tso rau hauv lub qhov cub, qhov uas nws raug rau qhov kub ntawm +180 txog +200 degrees. Nyob rau tib lub sijhawm, lub siab nce mus txog 8-14 atmospheres. Nrog aerated qhob, qhov xwm txheej sib txawv, nws tuaj yeem tawv ob qho tib si hauv lub tshuab nqus dej thiab hauv qhov cua qhib, nyob ntawm qhov sib txawv ntawm cov thev naus laus zis.

Kev kho siab yog suav tias yog qhov zoo dua vim nws muaj cov yam ntxwv hauv qab no:

• nce tus nqi ntawm kev teeb tsa;
• ua rau cov khoom muaj zog;
• guarantees geometry ruaj khov;
• hnyav heev txo qis kev siv.

Ob lub pa roj silicate thiab cov tshuab ua kom av autoclaved yuav luag dawb huv hauv cov xim. Tab sis cov xim grey tsis meej qhia tias cov qhob aerated yog nyob rau hauv pem hauv ntej ntawm cov neeg siv khoom, ua tiav yam tsis tau thov siab.

Kev tshuaj xyuas ntawm ib qho ntawm cov ntaub ntawv teev npe tau ua los ntawm kev suav nrog cov tsis xws li:

• ntom (tshwj xeeb lub ntiajteb txawj nqus);
• dej nqus;
• tshav kub kis;
• compression tsis kam - qhia lub zog ntawm cov neeg kho tshuab;
• Frost tsis kam - ntsuas nyob rau hauv tus naj npawb ntawm cov khov khov thiab thaw;
• dej vapor permeability;
• tag nrho cov tuab ntawm cov masonry.

Kev paub nrog cov yam ntxwv thev naus laus zis tseem ceeb qhia tau tias cov qhob aerated thiab cov roj silicate tsis zoo dua rau tus phooj ywg hauv cov hauv qab no:

• ncab hla cov tuab ntawm cov khoom;
• tiv thaiv hluav taws;
• kev tsim nyog rau kev txiav nrog tes saws;
• thaj chaw ecological;
• kev tiv thaiv kab mob khaub thuas;
• nqe;
• haum rau kev ua tiav nrog ntau yam ntawm cov hniav plaster.

Yuav xaiv thiab thov li cas?

Txhua yam no tsis tau txhais hais tias, txawm li cas los xij, qhov aerated concrete thiab gas silicate yeej sib koom ua ke txhua qhov. Hauv qhov no, qhov sib txawv twb tau tshwm sim hauv qhov muaj pes tsawg leeg ntawm cov kua nplaum muab los ntawm cov tuam txhab tsim khoom tshwj xeeb. Cov nplaum yog kev sib xyaw ua ke ntawm cov xuab zeb thiab cov cement, cov khoom tshwj xeeb uas tau txiav txim siab los ntawm cov tshuaj ntxiv. Nws tsuas yog ua tsaug rau cov khoom ntxiv uas nws muaj peev xwm them nyiaj rau qhov nrawm nrawm. Cov tshuaj astringent classic, txawm tias zoo heev, yuav tsis pab hauv qhov no.

Thaum sib piv cov ntaub ntawv sib txawv thiab sim ntsuas qhov twg yog qhov zoo dua, nws yog ib qho tseem ceeb kom nkag siab tias txhua qhov kev txiav txim no yog txheeb ze . Cov pa roj carbon silicate txhim kho los ntawm kev siab yuav tsum yog qhov ua tau zoo, tab sis ntau cov nyiaj ntxiv yuav tsum tau them rau lawv cov txiaj ntsig. Cov khoom siv roj tsawg ua rau tawg, tab sis qhov no yog "ncaj ncees" los ntawm kev tiv thaiv kev tiv thaiv kom tsis txhob tshav kub. Aerated qhob, tau txais yam tsis muaj autoclave, yog qhov tsis yooj yim, tab sis nws tuaj yeem tau txais ntawm nws tus kheej. Cov thaiv no yooj yim ua rau ntawm qhov chaw, txuag nyiaj. Cov pa roj silicate thaiv nyob rau hauv kev ua haujlwm zoo ib yam sib txawv los ntawm cov pob zeb ua kom zoo dua hauv yuav luag txhua lub zog, tshwj tsis yog rau kev nqus dej, yog li ntawd, cov roj silicate tsuas yog siv qhov uas cov av noo tsis tshaj 60%. Hauv cov xwm txheej hnyav dua, cov khoom degrades sai heev.

Tseem ceeb: yog tias dej nkag mus rau hauv qhov hws ntawm ob qho tib si thiab lwm yam khoom, qhov ntsuas cua sov tau txo qis.

Qhov no txhais tau tias lub ntsej muag yuav tsum tau tiv thaiv los ntawm huab cua noo.

Txhawm rau daws qhov teeb meem zoo sib xws, siv cov cuab yeej xws li:

• xim facade;
• plaster;
• sab;
• plaster nyob rau hauv daim ntawv ntawm ib tug nyias txheej.

Lub ntsej muag cib nrog qhov sib txawv rau cua tshuab (qhov sib txawv yog 300-400 mm) kuj tuaj yeem siv tau. Nws raug nquahu kom npog phab ntsa sab nrauv nrog lub ru tsev txuas ntxiv. Qhov loj dua nws, qhov tsis txaus ntshai nag lossis daus yog. Txhua cov ntaub ntawv ua tiav uas tau thov dua aerated qhob thiab roj silicate yuav tsum muaj qib zoo ntawm cov pa permeability. Yog tias qhov xwm txheej no tsis tau ntsib, yuav tsum muaj qhov cua nkag tau zoo.

Kev nkag mus ntawm cov pa los ntawm rwb thaiv tsev, pleev xim lossis plaster yuav tsum hnyav dua li los ntawm cov khoom siv. Pom zoo ntxiv rwb thaiv tsev siv cov ntaub plaub ntxhia. Thaum ua tiav lossis tiv thaiv tshav kub tau ua hauv ob peb txheej, kev nkag mus ntawm cov pa mus rau txhua txheej tom ntej yuav tsum muaj zog dua li mus rau txheej yav dhau los. Kev ua tsis tau raws li qhov yuav tsum tau ua no yuav ua rau muaj hws. Lub hnab ntim pwm yuav tshwm sai sai no.

Yog tias koj yuav tsum kho cov rooj tog raug tshem tawm ua los ntawm cov roj silicate lossis cov qhob aerated, cov dowels tau siv. Aerated qhob blocks yog ntxiv rau fastened siv thauj tog rau nkoj bolts. Rau ob hom kev teeb tsa, lub hauv paus nrog kev suav kom meej tsis thiab qhov ntev yuav tsum tsim. Nws kuj tseem pom zoo kom npaj cov dej tsis sib haum. Kev ntxiv dag zog yog ua tiav ntawm thawj thiab txhua kab thib plaub. Nws kuj tseem pom zoo kom txhawb lub qhov rooj thiab qhib qhov rai.

Cov Lus Qhia Ntxiv

Kev tsim tus kheej ntawm cov qhob aerated feem ntau ua tiav hauv cov ntawv, muab faib ua cov qauv loj. Kev yuav khoom ntawm cov khoom siv nyuaj thiab kim tsis txiav txim siab nws tus kheej. Nws yog ib qho tseem ceeb kom nco ntsoov tias nrog qhov nruab nrab qhov sib npaug zoo ib yam ntawm cov khoom, roj silicate khaws cov cua sov kom zoo dua. Yog li, nws raug nquahu kom siv nws hauv qhov chaw txias tshaj. Kev xaiv cov qhob aerated lossis cov roj silicate tsis cuam tshuam rau kev tsim kho nrawm.

Roj silicate kuj tseem zoo dua qhov uas xav tau kev txhim kho suab rwb thaiv tsev . Tab sis nws qhov kev tiv thaiv hluav taws yog qee yam tsis muaj zog, ib yam li nws lub neej ua haujlwm. Cov yam ntxwv zoo nkauj ntawm cov roj silicate siab dua li ntawm cov qhob aerated, tab sis nws tsim nyog nco ntsoov tias txhua yam yog qhov tsis yooj yim tsuas yog thaum piv cov ntaub ntawv yam tsis muaj sab nrauv. Yog li, qhov xwm txheej no tseem ceeb heev nrog kev txuag nyiaj ntau tshaj. Cov lus piav qhia qhov uas tau hais, peb tuaj yeem xaus: qhov kev xaiv zaum kawg tsuas yog nyob ntawm tus kheej qhov muaj feem thib tshwj xeeb, tshwj tsis yog qee tus neeg thaum qhov xwm txheej tso cai rau kev txiav txim siab tsis meej.
