Hnub no, nthuav dav perlite tau siv ntau hauv kev lag luam, suav nrog kev tsim kho. Ua cov khoom friable, nws yog ib qho tseem ceeb raws li ib tug muab tub lim thiab ci hmoov. Txawm tias muaj tseeb hais tias cov ntaub ntawv tau paub nyob rau hauv peb lub teb chaws rau ib ntev lub sij hawm, perlite tau dav siv tsis ntev los no xwb. Dab tsi yog nthuav perlite? Yam ntawm daim ntawv thov thiab ntau lawm nta.
Definition
Perlite yog lub pob zeb tsis pom kev uas yog cov khoom lag luam los ntawm cov hluav taws kub tawg. Cov khoom siv yog iav volcanic los ntawm cov dej hauv av nkag mus, yog li tsim cov qauv tshwj xeeb. Perlite yog tus cwj pwm los ntawm cov qauv uas nws tawg mus rau hauv me me nuclei. Nws tshuav nws lub npe rau qhov no.
Production
Expanded perlite yog tau los ntawm kev sib tsoo thiab kho cua sov obsidian volcanic iav. Lub o yog nqa tawm los ntawm txoj kev ntawm thermal shock nyob rau hauv900-1000 degrees. Thaum rhuab sai, cov pa roj tso tawm hauv cov khoom, uas tawg thiab muab cov khoom ua kom muaj kev sib haum xeeb.
Ntse
Nyob rau hauv tsos, nthuav perlite zoo li cov xuab zeb lossis pob zeb crushed ntawm ib feem zoo, nyob ntawm seb qhov kev sib tsoo. Nws muaj xim los ntawm daus-dawb mus rau dawb nrog greyish tint. Kev tsim cov perlite suav nrog nws qhov sib cais rau hauv ntau qhov feem - los ntawm cov hmoov perlite tsawg dua 0.14 hli loj rau perlite crushed pob zeb - 10-20 mm.
Ntxiv rau, cov khoom tau muab faib ua cov qib uas sib haum rau qhov ntom ntom ntawm nthuav dav perlite:
- M75 - mus txog 75 kg/m3.
- M100 - txog 100 kg/m 3.
- M150 - los ntawm 100 txog 150 kg / m 3.
- M200 - los ntawm 150 txog 200 kg / m 3.
- M250 - los ntawm 200 txog 250 kg / m 3.
- M300 - los ntawm 250 txog 300 kg / m 3.
- M350 - los ntawm 300 txog 350 kg / m 3.
- M400 - los ntawm 350 txog 400 kg / m 3.
- M500 - los ntawm 400 txog 500 kg / m 3.
Cov khoom siv sib txawv yog siv rau kev xav tau sib txawv. Lub thermal conductivity ntawm nthuav perlite kuj nyob ntawm qhov hnyav volumetric. Nws tuaj yeem sib txawv ntawm 0.034 W / Mk. Cov qib feem ntau siv yog nthuav dav perlite M 75.
Khoom zoo
Perlite feem ntau siv los ua cua sov, qhov no yog vim qhov tseeb tias nws muaj cov yam ntxwv zoo li no:
- Natural origin. Vim li no, cov khoom siv yogenvironmentally friendly thiab tsis muaj tshuaj impurities.
- Txoj kev loj hlob ntawm ntau yam kab mob yog tsis yooj yim sua nyob rau hauv perlite, thiab nas tsis pib nyob rau hauv nws.
- Perlite tsis muaj cov ntawv khi. Qhov no txhais tau hais tias thaum lub sijhawm ua haujlwm thiab khaws cia, nws tsis hloov nws lub cev thiab tsis ntsws.
- Cov khoom yog xoob thiab yog li vapor permeable. Qhov no ua rau nws muaj peev xwm evaporate cov dej noo ntau hauv chav.
- Perlite tsis yog cov khoom siv hluav taws xob, uas ua rau muaj kev nyab xeeb ntawm cov qauv uas nws siv los ua lub rhaub.
Ua tsaug rau cov khoom zoo no, nthuav dav perlite yog nrov hauv kev tsim kho.
YPlaster
Qhov ntom ntawm nthuav dav perlite ua rau nws siv tau cov khoom siv rau kev npaj cov tshuaj plaster. Lawv zoo haum rau thermal rwb thaiv tsev ntawm lub tsev, txij li ib txheej ntawm xws li plaster nrog ib tug tuab ntawm tsuas yog 3 cm hloov brickwork nyob rau hauv 1 cib.
Qhov zoo ntawm qhov sib tov yog tias nws tuaj yeem siv rau txhua qhov chaw - los ntawm ntoo mus rau slag pob zeb. Nyob rau tib lub sijhawm, xws li plaster tsis poob nws cov khoom. Rau nws cov kev npaj, perlite hmoov ntawm nplua feem yog siv. Tom qab ua tiav kom qhuav, xws li plaster tuaj yeem raug ua tiav - nws yog qhov sib npaug zoo rau kev pleev xim tom ntej thiab wallpapering.
Txiv neej
Nthuav perlite feem ntau yog siv los ua mortars uas yog siv los tso cib lossis lwm yamcov ntaub ntawv. Cov kev daws teeb meem zoo li no yog lub teeb, tib lub sijhawm ruaj khov thiab sov. Qhuav, nws hloov tawm masonry ntawm cib, cinder thaiv los yog ua npuas ncauj pob zeb, uas tsis muaj txias txuas hniav. Mortars kuj tseem siv los kaw ntau qhov khoob, pob qij txha thiab lwm yam tsis sib xws.
Txhawm rau npaj cov sib tov qhuav, perlite xuab zeb yog tov nrog gypsum lossis cement. Nws yog ib qho tsim nyog yuav tau dilute nrog dej tam sim ntawd ua ntej pib ua hauj lwm, vim hais tias xws li ib lub tsev sib tov yuav harden sai.
phab ntsa rwb thaiv tsev
Rau phab ntsa rwb thaiv tsev, perlite xuab zeb nrog ib feem ntawm 6 hli, yav tas los dedusted, yog siv. Nws yuav tsum tau muab tso rau ntawm brickwork. Cov txheej txheem tuaj yeem nqa tawm ob qho tib si manually thiab siv lub tshuab sandblasting. Thaum tso, nws yog ib qho tsim nyog yuav tsum coj mus rhaub cov phab ntsa kom lub sijhawm nthuav dav perlite. Lub thickness ntawm insulating ncoo feem ntau yog hais txog 5-10 cm.
ru tsev rwb thaiv tsev
Kev siv cov perlite nthuav dav tsis txwv rau phab ntsa rwb thaiv tsev, vim lub ru tsev kuj xav tau cov rwb thaiv tsev thermal ntxiv. Rau cov laj thawj no, ib feem ntawm cov khoom siv yog siv, zoo ib yam li qhov yuav tsum tau ua rau phab ntsa rwb thaiv tsev. Rau kev siv ntawm thermal rwb thaiv tsev, perlite yuav tsum tau nchuav ntawm lub sheathing thiab lub ru tsev lathing, ib ntus tapping kom zoo dua compaction ntawm cov khoom.
Nyobbituminized perlite yog siv, uas yog, tov nrog bitumen. Nws muaj cov qauv nplaum thiab ruaj khov. Qhov zoo dua yog qhov tseeb tias kev teeb tsa ntawm bituminized perlite tsis xav tau kev kho cua sov thiab kho nws tus kheej. Txawm li cas los xij, rau cov pib tshiab, nws yooj yim dua los siv cov khoom lag luam zoo tib yam, vim nws yooj yim dua los faib nws yam tsis muaj kev txawj ntse.
Pem teb rwb thaiv tsev
Kev rwb thaiv tsev ntxiv yuav xav tau tsis yog tsev ntiav xwb, tab sis kuj yog cov tsev nyob hauv ntau chav tsev. Txhawm rau ua qhov no, nws yog ib qho tseem ceeb kom tshem tawm qhov chaw los ntawm cov txheej txheem dhau los. Tsis tas li ntawd, qee qhov kev sib txuas lus lossis cov txheej txheem sov hauv pem teb feem ntau muab tso rau hauv qab lub screed.
Yuav kom insulate hauv pem teb nrog nthuav perlite, ua raws li hauv qab no:
- Tshem tawm cov txheej txheej qub kom tiav thiab, yog tias tsim nyog, txheej pob zeb.
- Fine perlite yog siv rau rwb thaiv tsev - txog li 6 hli.
- Nws yuav tsum tau nchuav rau hauv ib txheej. Feem ntau, nws yog li 3-5 cm, qhov no yog txaus los nkaum qhov tsis sib xws ntawm hauv pem teb thiab ua thermal rwb thaiv tsev.
Tom qab cov perlite tau nchuav tawm, nws yuav tsum tau maj mam tamped thiaj li ua kom nws sib haum. Tom qab ntawd, hauv pem teb yog npaj rau pouring qhob screed.
YPerlite khoom
Hnub no, ntau cov khoom tsim tawm, txhua tus muaj nws tus yam ntxwv:
- Silicate perlite yog cov khoom siv uas tseem muaj cov txiv qaub, xuab zeb, tshauv lossis slag. Nyob rau tib lub sijhawm, cov khoom xyaw yog sib xyaw thiab ci hauv pwm hauv autoclave.
- Bitumen perlite yog kev sib xyaw ua ke ntawm kev nthuav dav perlite nrog kua bitumen. Feem ntau siv rau hydro thiab thermal rwb thaiv tsev ntawm ru tsev.
- Carboperlite yog qhov loj ntawm qhov nthuav dav perlite xuab zeb thiab txiv qaub, ua raws li kev kho roj. Qhov tshwm sim yog cov khoom rau rwb thaiv tsev ntawm cov kav dej.
- Gypsum perlite - kev sib txuas ntawm nthuav dav perlite nrog gypsum los ntawm casting lossis semi-qhuav nias.
- Ceramoperlite yog kev sib xyaw ntawm perlite thiab av nplaum ua raws li kev kho cua sov.
Dhau li ntawm qhov no, hauv kev tsim kho kuj tseem siv rau cov khoom lag luam xws li iav-perlite, bas alt-perlite fibrous khoom, plastperlite, perlite-muaj cib, asbestos-perlite cement, perlite-cement non-combustible boards.
