Yuav ua li cas yog cov kev ceev ntawm bricks?

Cib - nws yog ib lub npe nrov tshaj lub tsev ntaub ntawv. Nws muaj ib tug xov tooj ntawm ib qho tseem ceeb thaj chaw uas ua rau nws irreplaceable. Cib resistant rau nag, yog tau withstand ntau mus ntawm khov, etc. Ib yam ntawm cov loj cov yam ntxwv ntawm lub tsev cov ntaub ntawv uas - .. Ceev. Nws txhais nws zoo xws li thermal conductivity, qhov hnyav thiab lub dag lub zog.

tej hub cib

Paub rau tag nrho cov khoom nyob rau hauv liab, txawm hais tias niaj hnub siv tshuab tau tso cai los nthuav rau tus xov tooj ntawm ntxoov. Ceev tej hub cib muaj ib tug dav variation, piv txwv li. K. Nws ua rau txawv hom phiaj. Ua ib tug cib ntawm av nplaum, uas yog ci nyob rau hauv tshwj xeeb ncu. Faib nws rau khoom thiab hollow. Nyob rau hauv thawj cov ntaub ntawv, cov kev ceev tej hub cib yog 2000 kg / m ^3. Nws ua tim khawv rau nws uas tsis muaj porosity thiab siab zog. Yog li ntawd cib siv rau qhov kev siv ntawm load-tau cov kabmob phab ntsa thiab lug, txhua thiab thiaj li nyob. D.

Hollow cib yog tsis yog li ntawd tuab. Qhov no xam nws yog hom twg 1100-1400 kg / m ^3. Nws yog undesirable los siv rau kev tsim kho ntawm load-tau cov kabmob lug. Hollow cib siv rau qhov kev siv ntawm khaub-ncaws nyias phab ntsa thiab sau tus ncej. Vim nws emptiness, nws muaj zoo heev thermal thiab suab rwb thaiv tsev zoo.

silicate cib

Ua los ntawm ib tug sib tov ntawm txiv qaub thiab xuab zeb. Qhov no cov ntaub ntawv uas yog pheej yig, yuav pleev xim rau nyob rau hauv lub feem ntau sib txawv xim, tab sis nws puv tsis ruaj tsis khov (raws li muab piv nrog tej hub), qhov hnyav thiab lub teeb kis tau tus mob khaub thuas thiab kub. Vim hais tias ntawm cov qualities no tsuas siv rau cov kev siv cov cib kev siv ntawm sab hauv partitions. Daim ntawv thov ntawm no cov ntaub ntawv uas los ua ib tug load-tau cov kabmob phab ntsa yog tsis tsim nyog. Tsis tas li ntawd, tsis txhob siv nws rau qhov kev siv ntawm furnaces, t. Yuav kom. By cua sov nws deforms.

Cov kev ceev ntawm silica cib corpulent yog 1800-1950 kg / m ³ thiab nrog voids - 1100-1600 kg / m ^3.

clinker cib

Tsim los ntawm cov qhuav av nplaum uas yog calcined ntawm txhawb kub. Raws li ib tug tshwm sim, cov khoom tau yog heev muaj zog thiab check. Qhov no cov ntaub ntawv uas yog tsis ntshai ntawm ntxooj thiab yooj yim khiav hauj lwm tej yam kev mob. Yog li ntawd, nws yog siv nyob rau hauv qhov chaw uas muaj load: lub paving ntawm txoj kev, cov kev siv cov av pem teb. Zoo nws manifests nws tus kheej thiab nyob txojkev tsev.

Corpulent clinker bricks ceev nce mus txog 1900-2100 kg / m ^3, lub dag lub zog - M1000. Lub porosity ntawm tsawg tshaj li 5%, yog li ntawd me ntsis cov ntaub ntawv uas yog raug rau dej. Cov khoom siv yog tsim rau 100 freeze-thaw mus. Txawm li cas los, zus tau tej cov xws li ib tug cib ntau npaum li cas kim tshaj tej hub. Vim hais tias ntawm cov kev kub ceev cov ntaub ntawv uas yog tau hnyav thiab muaj ib tug high theem ntawm thermal conductivity.

aluminous cib

Qhov no tsev cov ntaub ntawv uas yog npaj rau cov kub kub, nws muaj peev xwm mas tshav kub mus rau 1600 degrees. Yog li ntawd, fireclay bricks yuav hu ua tsis tau tsuas yog fireproof thiab hluav taws-resistant. Nws yog qhov tseem ceeb thaum pw rauv taws nte, fireplaces thiab lwm yam uas yuav tsum tau raug mus sov siab. Txij li thaum cov khoom no feem ntau yog siv rau dai kom zoo ntawm sab hauv decorating khoom, nws ua tsis tau tsuas yog txheej txheem lub zoo lawm, tab sis kuj arched, Trapezoid thiab cov sphenoid. Cib ceev yog hom twg los ntawm 1700 mus 1900 kg / cm ^3.

Txawm li cas los, peb pom tias cov khoom yog txwv kom muab zais tsis tau tsuas yog nyob rau hauv lub chaw ua khoom ntawm cov khoom, tab sis kuj rau lwm cov laj thawj. Yog li ntawd, muaj ntau yam ntawm cov yam ntxwv yuav tsum ua precisely hauv daim ntawv thov cheeb tsam. Nrog cov kev xaiv ntawm cov ntaub ntawv yuav nyob ntawm seb qhov no.

txojkev cib

Siv rau masonry los ntawm sab nraum ntawm vaj tse. High xav tau yog muab tso rau hauv nws cov tsos. Cib yuav tsum tiaj tus, du thiab glossy. nws yog hollow, li no ua tau zoo ob zog. Cov txheej txheej ntawm bricks ntawm ib lub sij hawm yog dai kom zoo nkauj thiab insulated. Rau lwm masonry khoom siv nyob rau hauv cov xim txawv. ntau yam ntawm cov xim yog tiav los ntawm kev siv ntau yam firing technology, kub regimes thiab nyob tus yeees ntawm cov av nplaum loj.

Cov kev ceev ntawm lub cib hauv ob sab phlu yog nyob rau hauv ntau ntawm 1300 mus 1450 kg / cm ³ thiab porosity yuav ncav cuag 14%. Qhov no yog txaus los xyuas kom meej ib theem siab ntawm lub zog, tab sis tsis txhob hnov qab txog lub tshav kub-insulating zog. Heev uas yuav tsum tau te khoom t. K. Nws tiv tauj nrog cov sab nraud ib puag ncig.

Private cib

Siv rau hauv tej hauj lwm, erection ntawm phab ntsa thiab hais txog. D. Muaj cais high-zog cib, uas yog siv rau kev tsim kho ntawm load-tau cov kabmob lug. Nyob rau hauv thawj cov ntaub ntawv, ib tug qhia xws li thwv cib ceev yog hom twg los ntawm 1100 mus rau 2000 kg / cm ^3, nyob ntawm seb daim ntawv thov. Yog li, sau tus ncej thiab / los nrog bulkheads ntaus ntawv yog siv hollow cib, t. K. Nws yuav tsis thauj cov foundation. Rau sab nraud los yog load-tau cov kabmob phab ntsa yog zoo tshaj plaws nqa mus siv rau cov high-zog cov ntaub ntawv uas. Cib ceev nyob rau hauv cov ntaub ntawv no tshaj 2000 kg / cm ^3.
