Autoclaved aerated qhob: zus, lub Scope ntawm daim ntawv thov, tshwj xeeb tshaj yog cov ntaub ntawv uas

Qhov no hom ntawm ntxeem tau qhob rau ib ntev lub sij hawm yog nyob rau hauv daim ntawv teev cov thawj lub tsev ntaub ntawv. Yog li ntawd, nws yog koom nyob rau hauv raug ntawm ntau factories thiab tuam txhab uas muag. Nrog rau txoj kev loj hlob ntawm technology yuav pom autoclaved aerated qhob nyob rau hauv ntau daim, ntau thiab tsawg thiab xim.

Autoclaved aerated qhob muaj peb lub ntsiab Cheebtsam:

• MAAs;
• quartz xuab zeb;
• blowing agents.

qauv

Nws vaj tse ib pore loj mus txog peb millimeters. Nws yog suav tias yog ib daim ntawv ntawm cellular qhob. Tag nrho cov nyob rau hauv lub pob zeb mix - knitting hauv paus, muab tub lim thiab dej. Aerated qhob yuav txwv kom muab zais los ntawm hom ntawm phau ntawv nyob rau hauv rau lub hauv paus, nws yuav ua tau:

• MAAs;
• txiv qaub;
• slag;
• gazogips.

High heev twb autoclaved aerated qhob raws li MAAs nrog txiv qaub.

Nyob rau hauv thiaj li yuav ua tau lub ntxeem tau qauv ntawm qhob tsim tshuaj cov tshuaj tiv thaiv, nyob rau hauv uas cov roj tso. Yuav kom tsim xws li ib tug txheej txheem siv ib tug txhuas hmoov los yog muab tshuaj txhuam. Yog hais tias koj xav muab ib tug tshwj xeeb cov khoom siv zog, ntxiv tshuaj nkag tau rau hauv nws cov muaj pes tsawg leeg.

raug dab

Tau autoclaved aerated qhob yuav ua tau nyob rau hauv no txoj kev: es nyias qhob sib tov yog poured mus rau hauv tshwj xeeb pwm mus rau ib nrab volume. Txawm li cas los, cov kev sib tsoo load ua rau nws. Yog li muaj ib tug xaiv ntawm tshav kub los ntawm lub slaking. Qhov kub ntawm lub autoclave yog nce mus rau 80 degrees.

Tom qab ntawd cov tshuaj tiv thaiv ntawm txiv qaub nrog txhuas, nyob rau hauv uas cov pa yog hloov zuj zuj. Vim li no cov pob zeb loj ntawm lub nce mus rau lub ntug ntawm daim ntawv no. Siab li cov kub nce. Nyob rau hauv tus ntawm cov tsiaj ntawv MAAs hardens, lub pores li nyob twj ywm, thiab muaj hauv lawv cua es tsis txhob ntawm hydrogen. Yog li yog tsim thiab pob zeb ua qauv, nyob rau lub pores nyob mus txog 80 feem pua volume. Puas Pab cov feem pua porosity los hloov tus nqi ntawm txhuas hmoov.

Ob teev tom qab solidified loj muab tshem tawm los ntawm lub autoclave thiab tsim txiav feem rau cov kev kawm loj. Ces tiav lawm blocks raug xa rov qab mus rau lub autoclave, qhov twg yuav muaj tag nrho hardening tsuas yog tom qab 12 teev. Thaum zoo li no kub mob yuav tsum tsis qis tshaj li 190 degrees ntawm ib tug siab ntawm 1.2 MPa.

Feem ntau, tus nqi ntawm cov xis mas ua vaj tse yog tsis ntau tshaj li 20%, thiab feem ntau siv Portland MAAs. Qhov loj ntim autoclave aerated qhob muaj quartz xuab zeb (kwv yees li 60%). Txiv qaub raws li zoo raws li MAAs, tsis ntau tshaj 20%. Lub txhuas ntsiab lus tej zaum yuav tsawg tshaj li ib feem pua.

Manufacturers ntawm AAC nyob rau hauv lawv cov qhauj cuag siab thiab kub ntawm cov tivthaiv yog tsim los ntawm ib tug tshwj xeeb mineral - tobermorite. Nws yog vim rau qhov cov tsim cov ntaub ntawv uas muaj siab zog thiab yog tsis raug mus rau shrinkage. Ib qho tseem ceeb nam ntawm dag tej yam kev mob yog hais tias cov ntau lawm lub sij hawm yog txo, uas tso cai rau ua loj cooling.

ntau lawm voj voog

Raug nyob rau hauv cov qauv ntawm cov ntau lawm txheej txheem nyob rau hom ntawm cellular qhob no yog ua los. Common dab yog:

• kev npaj ntawm qhov yuav tsum tau tus xov tooj ntawm Cheebtsam;
