Daim ntawv thov ntawm Alkali Resistant iav Fiber Mesh Cloth nyob rau sab nrauv phab ntsa Thermal rwb thaiv tsev System
Raws li cov ntaub ntawv tseem ceeb, thaj tsam ntawm lub tsev tsim nyob rau hauv kuv lub teb chaws txhua xyoo yog siab li 1.6-2 billion square meters, yuav luag ntau tshaj qhov sum ntawm lub xyoo tsim kho cheeb tsam ntawm tag nrho cov tsim lub teb chaws. Ntawm cov tsev tshiab no, tsuas yog 10-15 tuaj yeem ua tau raws li cov qauv kev txuag hluav taws xob hauv teb chaws, thiab ntau dua 80 yog cov tsev siv hluav taws xob siab, thiab kev siv hluav taws xob hauv ib cheeb tsam tsev yog 2-3 npaug ntawm kev tsim lub teb chaws. Yog li ntawd, kuv lub teb chaws txoj kev txuag hluav taws xob yuav tshwm sim. Thaum Lub Xya Hli 1996, "Civil Building Energy Conservation Standard (Heating Residential Buildings)" tau tshaj tawm thiab siv. Qhov "Standard" siv kuv lub teb chaws lub zog siv hluav taws xob hauv xyoo 1980 los ua tus qauv, thiab xav kom cov tsev nyob tshiab kom txuag tau 50 feem pua ntawm cov cua sov siv hluav taws xob, ntawm 30 feem pua yog ua tiav los ntawm kev txhim kho thermal rwb thaiv tsev kev ua tau zoo ntawm lub tsev hnab ntawv. Nyob rau hauv lub tsev lub hnab ntawv, cov phab ntsa suav rau qhov loj tshaj plaws kev faib ua feem ntawm cov cua sov zog noj, accounting txog li 32.1 txog 36.2 ntawm tag nrho cov zog noj. Yog li ntawd, yuav ua li cas los txhim kho cov thermal rwb thaiv tsev ntawm phab ntsa ua qhov tseem ceeb tshaj plaws. Nws yog nyob rau hauv lub hauv paus ntawm qhov kev nkag siab no uas tib neeg paub tias nws yog ib qho tsim nyog yuav tsum tau ua kom tiav thiab txhawb nqa cov txheej txheem tshiab ntawm phab ntsa rwb thaiv tsev thiab cov ntaub ntawv rwb thaiv tsev.
Sab nrauv phab ntsa rwb thaiv tsev tshuab
Tam sim no, sab nrauv phab ntsa rwb thaiv tsev ntawm lub zog txuag lub tsev nyob hauv kuv lub teb chaws tau muab faib ua plaub hom thermal rwb thaiv tsev: sab hauv thermal rwb thaiv tsev, sandwich thermal rwb thaiv tsev, thermal rwb thaiv tsev sab nraud thiab kev thermal rwb thaiv tsev. Sab nrauv thermal rwb thaiv tsev ntawm cov phab ntsa sab nrauv yog lub ntsiab thermal rwb thaiv tsev daim ntawv tawm tswv yim thiab txhawb nqa los ntawm Ministry of Construction. Zoo, nws yog cov cuab yeej siv hluav taws xob ntau tshaj plaws hauv peb lub tebchaws. Lub tsev thermal rwb thaiv tsev tshuab no yog muab cov txheej txheem thermal rwb thaiv tsev rau sab nraud ntawm phab ntsa sab nrauv, kom qhov kub ntawm qhov sib txawv ntawm cov qauv tseem ceeb txo qis, qhov kub deformation txo, cov txheej txheem phab ntsa tiv thaiv thiab txias (kub kub. ) tuaj yeem thaiv tau zoo. ) choj, uas muaj txiaj ntsig zoo rau lub neej ntev ntawm cov qauv. Niaj hnub no, sab nrauv phab ntsa rwb thaiv tsev (eifs los yog etics) tau siv rau kev tsim cov phab ntsa sab nrauv thoob plaws ntiaj teb, uas tsis tsuas yog ua tiav cov txiaj ntsig ntawm kev txuag hluav taws xob txuag 30-70 feem pua ntawm kev siv hluav taws xob cua sov thiab cua txias, tab sis kuj muab ib qho chaw noj qab haus huv thiab xis nyob rau tib neeg. Nyob ib puag ncig. Yog li ntawd, nyob rau hauv txoj kev rwb thaiv tsev phab ntsa, sab nrauv phab ntsa rwb thaiv tsev tshuab tau dav siv.
1. kuv lub teb chaws uas twb muaj lawm sab nrauv phab ntsa rwb thaiv tsev
Lub Tsev Haujlwm Saib Xyuas Kev Tsim Kho "Cov Phab Ntsa Sab Nraud Sab Nraud Sab Nraud Thermal Insulation Engineering Technical Regulations" pom zoo tsib lub thermal rwb thaiv tsev rau sab nrauv phab ntsa: EPS board nyias plaster sab nraud thermal rwb thaiv tsev system; roj hmab hmoov EPS particle thermal rwb thaiv tsev slurry sab nraud thermal rwb thaiv tsev system; EPS board cam khwb cia-nyob rau hauv-qhov chaw ua vaj tse sab nraud thermal rwb thaiv tsev system (xws li net thiab tsis muaj net ob); mechanical anchoring eps steel hlau mesh ncej board sab nraud rwb thaiv tsev system. Lwm cov phab ntsa rwb thaiv tsev nyob rau hauv txoj kev loj hlob xws li xps board sab nrauv rwb thaiv tsev, polyurethane nruj npuas sab nrauv rwb thaiv tsev, rwb thaiv tsev thaiv thiab prefabricated rwb thaiv tsev board sab nrauv rwb thaiv tsev system thiab pob zeb ntaub plaub sab nrauv rwb thaiv tsev, thiab lwm yam.
Nyob rau hauv xyoo tas los no, ntawm ntau cov txheej txheem ntawm sab nrauv phab ntsa thermal rwb thaiv tsev, EPS board nyias plaster sab nraud thermal rwb thaiv tsev yog qhov nrov tshaj plaws nyob rau hauv kev ua lag luam. Tsis tsuas yog nyob rau hauv Suav teb, tab sis kuj nyob rau hauv lub teb chaws tsim thiab cheeb tsam xws li cov teb chaws Europe thiab lub tebchaws United States, lub EPS board nyias plaster sab nrauv rwb thaiv tsev system kuj yog ib tug nyiam system. Cov qauv yooj yim ntawm nyias plaster sab nrauv thermal rwb thaiv tsev yog luv luv qhia.
2. Kev tsim kho ntawm EPS board nyias plaster sab nrauv rwb thaiv tsev
(1) Basic phab ntsa
Sab nrauv phab ntsa ntawm ib lub tsev uas ua raws li kev thauj khoom lossis kev kaw. Sab nrauv phab ntsa yuav tsum muaj zog thiab qhuav, thiab pwm yuav tsum tau muab tshem tawm ua ntej txhim kho cov rwb thaiv tsev sab nraud.
(2) Adhesive
Ua los ntawm ib qho kev faib ua feem ntawm kev sib koom ua ke mortar thiab polymer, nws yog siv los khi cov khoom siv rwb thaiv tsev rau lub hauv paus phab ntsa. Yog li ntawd, nws yuav tsum muaj cov khoom sib txuas zoo rau ob sab nrauv phab ntsa thiab cov ntaub ntawv rwb thaiv tsev.
(3) Daim ntawv nplaum
Tam sim no, ob hom adhesives, ib hom khoom thiab ob lub ntsiab lus, tau siv dav hauv kev tsim kho: ib qho khoom siv yog cov hmoov qhuav qhuav uas yog sib xyaw ua ntej thaum lub sij hawm tsim khoom, thiab ib feem ntawm cov dej ntxiv. thiab nplawm raws li cov lus qhia ntawm qhov chaw tsim kho. Ntawd yog, nws txoj kev tsim kho thiab kev ua haujlwm tau yooj yim, cov khoom siv tau ruaj khov, thiab nws yog cov khoom siv zoo ib puag ncig; ob hom yog hais txog kev tsim cov kua nplaum (cov khoom a) thiab cov hmoov tshwj xeeb (cement, quartz xuab zeb, additives, tivthaiv b). Qhov chaw tsim kho tuaj yeem muab tso rau hauv kev siv tom qab sib tov sib npaug raws li cov lus qhia rau kev siv. Nws lub zog sib txuas yog siab dua li ntawm ib qho kev tivthaiv, tab sis kev cia khoom, kev thauj mus los thiab kev tsim kho kev lag luam yog ntau cumbersome, thiab tib neeg yuam kev yuav tshwm sim thaum siv, uas tsis yog ib puag ncig tus phooj ywg.
(4) Cov khoom tseem ceeb ntawm cov nplaum - polymer
Tam sim no, cov nplaum polymers siv nyob rau hauv lub rwb thaiv tsev sab nraud ntawm polystyrene rwb thaiv tsev boards nyob rau hauv Tuam Tshoj muaj xws li ntshiab acrylic emulsion, styrene-acrylic emulsion, vinegar-acrylic emulsion thiab vinyl acetate-ethylene copolymer emulsion (vae emulsion, hu ua txawv teb chaws), thiab lwm yam. Txawv teb chaws feem ntau yog acrylic thiab yas acetate copolymer emulsion. Los ntawm cov khoom lag luam emulsion uas nkag mus rau Suav lag luam, muaj cov khoom lag luam los ntawm Tebchaws Meskas, cov khoom lag luam ntawm South Kauslim tuam txhab, thiab lwm yam, tag nrho cov no yog ua los ntawm acrylic; thaum cov khoom siv hmoov qhuav uas nkag mus rau Suav lag luam, txawm tias lawv yog cov khoom lag luam los ntawm Tebchaws Meskas, Lub Tebchaws Yelemees, Fabkis, Nyiv, lossis Kaus Lim Qab Teb Vinyl acetate copolymer emulsion qhuav hmoov feem ntau yog siv. Piv nrog rau cov khoom siv acrylic, vinyl acetate copolymer emulsion qhuav hmoov cov khoom muaj kev ua tau zoo tag nrho, feem ntau hauv:
① Siab pib viscosity. Nws muaj txiaj ntsig zoo rau qhov chaw ntawm lub rooj tsav xwm polystyrene thiab tiv thaiv cov iav fiber ntau los ntawm kev sib tsoo thaum lub sij hawm tsim kho.
② Kev sib txuas ua ke ua haujlwm tau zoo. Nyob rau hauv cov txheej txheem thermal rwb thaiv tsev sab nraud, phab ntsa matrix thiab alkali-resistant mesh yog cov khoom siv polar, thiab polystyrene board yog cov khoom tsis-polar. Acrylic acid polymer yog polar, yog li nws muaj kev sib raug zoo nrog cov phab ntsa substrate thiab alkali-resistant mesh daim ntaub thiab qis kev sib raug zoo nrog polystyrene board; nyob rau hauv vinyl acetate copolymer emulsion, nws cov qauv muaj ob pawg Polar, kuj tseem muaj pawg polar, yog li kom muaj kev sib koom ua ke zoo dua tuaj yeem tau txais.
(5) Eps board
Eps board ua cov khoom siv rwb thaiv tsev.
