Muab qhov nrawm ntawm kev tsim cov tsev tshiab, nrog rau qhov xav tau los tsim cov khoom vaj khoom tsev tshiab, nws yuav tsum tau muab sau tseg tias cov xuab zeb-lime cib feem ntau yog siv los ua cov khoom siv rau phab ntsa. Qhov no yog cov khoom siv tau thiab txhim khu kev qha. Peb yuav xav txog cov yam ntxwv, cov khoom thiab muaj pes tsawg leeg ntawm silicate cib nyob rau hauv peb tsab xov xwm hnub no.

Kev sib xyaw thiab cov yam ntxwv

Lub cib no tau nthuav dav hauv Russia. Txawm hais tias qhov yooj yim ntawm kev ua tiav ntawm cov khoom siv hauv tsev no, nws ib txwm tau nthuav dav seb silicate cib ua los ntawm. Cov muaj pes tsawg leeg ntawm cov khoom no yog raws li nram no:

• Kev sib xyaw tshwj xeeb ua los ntawm slag thiab tshauv.
• Slurry.
• txiv qaub siv hauv kev tsim kho.
• Sand, uas yog siv los tsim cov khoom siv silicate.
• Slag xuab zeb.
• Dej yog suav nrog hauv cov kuab tshuaj silicate.
• Chromium oxide yog siv los ua cov khoom tiv thaiv alkalis.

Ash-slag sib tov yog siv los ua kom cov thermal rwb thaiv tsev ntawm cov khoom tiav. Tsis tas li ntawd, qhov sib tov no txo qhov ntom, tab sis ua kom lub zog ntawm lub cib. Ntxiv mus, qhov sib tov no feem ntau tshem tawm tag nrho cov khoom siv xws li quartz xuab zeb. Lub luag haujlwm tshwj xeeb hauv kev tsim khoom yog ua si los ntawm qhov tseeb tias dej siv me me, uas yog, tsis yog cov dej sib tov tau txais, tab sis cov khoom zoo, tsuas yog me ntsis moistened thiaj li tsim cov khoom tiav. Lub tshuab no tso cai rau:

• Ua kom cov khoom cib pheej yig dua, raws li, tus nqi ntawm cov khoom tiav txo qis, uas ua rau nws pheej yig dua.
• Lub sijhawm tsim khoom rau cov khoom no raug txo los ntawm 15%.

Cov khoom ntawm silicate cib yog thawj zaug tswj hwm los ntawm kev cai lij choj thiab qee cov qauv. Lawv yuav muaj npe hauv qab no.

Silicate cib thiab GOST

Cov muaj pes tsawg leeg thiab cov yam ntxwv ntawm silicate cib yog tswj los ntawm cov ntaub ntawv hauv qab no:

1. SNiP 3.03.01-87 "Cov Kabmob thiab cov txheej txheem enclosing".
2. GOST 379-95 "Cib thiab silicate pob zeb".
3. GOST 23421-79 "Txuas rau kev thauj mus los ntawm cov xuab zeb-txiv qaub cib".

Ntau yam

Txawm hais tias muaj qee yam qauv rau kev tsim cov khoom siv hauv tsev, muaj pes tsawg leeg ntawm silicate cib raws li GOST muab rau ntau yam:

• Ua ntej hauv cov npe los ntawm cov khoom tsim tawmyog lime-ash cib. Nws feem ntau muaj cov tshauv, uas yog 80% ntawm tag nrho cov huab hwm coj thiab txiv qaub, cov ntsiab lus uas yog 20% ntawm pawg.
• Hauv qhov chaw thib ob ntawm kev tsim khoom yog slag-lime cib, los ntawm lub npe uas koj tuaj yeem nkag siab tias qhov tseem ceeb muaj slag, thiab qhov no yog kwv yees li 90%, thiab txiv qaub, uas ua rau 10 seem. %. Nyob rau hauv cov ntaub ntawv no, raws li tau hais ua ntej lawm, muaj pes tsawg leeg ntawm silicate cib tsis suav nrog kev siv quartz xuab zeb ua ib feem, uas muaj feem xyuam rau cov khoom ntawm cov khoom.
• thib peb rau txiv qaub-xuab zeb cib. Tsis zoo li hom yav dhau los, quartz xuab zeb yog siv los ua cov khoom tseem ceeb. Tsuas yog 10% ntawm tag nrho cov muaj pes tsawg leeg yog txiv qaub.

Qhov ntau thiab cov duab

Txhua qhov kev tsim khoom siv zog ua kom tau raws li qhov xav tau ntawm cov neeg siv khoom ntau li ntau tau, yog li ntawd, dhau sijhawm, ntau yam kev hloov kho tau tshwm sim uas tau txais cov cim "U" thiab "O". Nws txhais li cas:

• Kev kos "O" qhia tias qhov no yog tus qauv, ib qho cib, ntsuas 250 × 120 × 65 millimeters. Qhov loj ntawm cov khoom tiav raws li tus qauv yuav tsum tsis pub tshaj 3.8 kilograms.
• Yog tias cov khoom tiav yog cim "Y", qhov no qhia tias hom no yog thickened. Qhov ntev sib txawv tsuas yog nyob rau hauv thickness tsis, xws li 250 × 120 × 88 millimeters, nrog ib tug loj ntawm 4.3 kilograms.

Kev hloov kho

Nws tseem tuaj yeem tawg silicate cib rau hauv subspecies, nyob ntawm nws qhov kev hloov kho. Raws li cov kev txwv nopaub qhov txawv ntawm hollow cib thiab khoom. Nws tsis tuaj yeem txiav txim siab tag nrho cov kev hloov pauv tau. Ib qho tseem ceeb yog tias lawv muaj qhov sib txawv thermal conductivity thiab lub zog. Tab sis txawm li cas los xij, cov chaw tsim khoom tuaj yeem ua tiav qhov kev txiav txim ntawm tus neeg yuav khoom, uas yog, qhov feem pua ntawm hollowness sib txawv mus txog 40%, tab sis tib lub sijhawm, cov chaw tsim khoom tsis tuaj yeem lav lub zog, txij li cov kev hloov pauv rau cov tsis tau teev tseg los ntawm GOST tsis yog. raug rau cov ntaub ntawv pov thawj thiab txhua yam ua tiav ntawm kev ntshai thiab kev pheej hmoo ntawm tus neeg siv khoom. Thaum siv cov hollow bricks, thermal conductivity ntawm lub tsev cov ntaub ntawv yog pom tau tias zoo dua. Qhov no nce tus nqi ntawm kev teeb tsa, nrog rau tus nqi ntawm cov khoom sib tov.

Structure of sand-lime brick

Lwm qhov ntsuas yog qhov ntsuas ntawm cov khoom. Cib feem ntau yog cov cib ntxhib, uas yog siv rau hauv lub ntsiab masonry ntawm lub tsev thiab tom qab ntawd yuav muab zais rau hauv cov ntaub ntawv zoo nkauj. Lub luag haujlwm ntawm cov cib no yog tsim kom muaj kev ncaj ncees ntawm cov qauv, muab lub zog tsim nyog, suab rwb thaiv tsev, thiab thermal conductivity ntawm lub tsev. Hom no tso cai rau qee qhov chips thiab kev puas tsuaj me, uas tsis yog qhov tseem ceeb. Facing silicate cib kuj tsim, lub hom phiaj ntawm uas yog muab cov tsos ntawm cov tiav lawm qauv. Outwardly, nws muaj cov qauv nyem, nrog rau cov xim sib txawv, uas hloov ob qho tib si ntawm cov theem tsim khoom (los ntawm kev ntxiv xim) thiab tom qab tsim cov khoom tiav, los ntawm qhov chaw staining.

Qhov txiaj ntsig tseem ceeb

Muab qhov hnyav, qhov ntev, cov duab, kev hloov kho, kev siv, nrog rau kev sib xyaw ntawm cov xuab zeb-txiv qaub cib, muaj ntau yam zoo uas ua rau nws xav tau hauv kev tsim kho lub sijhawm ntev:

• Lub sijhawm dhau mus, silicate cib tau txais kev nruj ntxiv vim qhov sawv, uas tseem cuam tshuam rau nws cov Frost tsis kam.
• Muaj peev xwm xaiv ntau yam ntawm cov khoom tiav. Hollow cib plays lub luag haujlwm tseem ceeb tshwj xeeb. Qhov tseeb yog qhov kev hloov kho no tso cai rau koj siv lub hauv paus tsis tshua muaj zog, thiab thaum tsim chav loj, qhov no tseem ceeb heev.
• Tsis muaj peev xwm rho tawm ntsev. Raws li tau rov pom dua hauv ntau lub tsev, cov pob dawb tsim ntawm qee ntu ntawm phab ntsa. Qhov tshwm sim no yog vim lub sijhawm dhau los, lub cib poob dej, thiab tib lub sijhawm tso cov ntsev, uas feem ntau cuam tshuam rau cov hniav zoo nkauj.
• Versatility of use. Feem ntau, kev tsim cov kev daws teeb meem muaj cov duab tsis zoo thiab cov qauv tsim, uas tsuas yog tsis yooj yim sua kom paub thaum siv cov khoom siv hauv tsev loj. Lub cib muaj qhov me me, ua tsaug uas nws tsim nyog rau kev siv txawm tias cov kev daws teeb meem zoo tshaj plaws.
• 100% kev tsim khoom ruaj khov.
• Lub suab rwb thaiv tsev zoo yog qhov tseem ceeb. Ua raws li tag nrho cov cai thiab cov cai rau kev tsim vaj tsev thiab chaw ua haujlwm, silicate cib tso caiua tiav qib siab tshaj plaws ntawm lub suab rwb thaiv tsev piv rau lwm yam khoom siv hauv tsev. Nws yog qhov yooj yim dua nyob hauv cov tsev zoo li hauv vaj huam sib luag. Nyob rau tib lub sij hawm, cov phab ntsa tsis tas yuav tsum tau ntxiv insulated thiab insulated nyob rau hauv txhua txoj kev.

Cib daim ntaub ntawv

Sand-lime cib yog cov khoom siv nrov heev, cov khoom sib xyaw uas ua tau raws li kev lees paub thiab cov qauv. Nws yog siv nyob rau hauv yuav luag txhua qhov chaw ntawm kev tsim kho. Yog li, koj tuaj yeem pom cov tsev tsev loj thiab cov tsev ntiav uas siv nws. Cov khoom siv kuj tseem siv rau hauv kev tsim kho ntawm cov phab ntsa sab hauv thiab cov partitions, laj kab nyob ze cov tsev nyob rau hauv lub private sector, thiab txawm qhov cua ducts.
