Yuav ua li cas yogpolyurethane rigid ua npuas ncaujsiv rauCov khoom siv hauv tsev?
Kev tsim vaj tsev yog ib qho tseem ceeb tshaj plaws ntawm daim ntawv thov ntawm PU rigid foam.
PU rigid ua npuas ncauj rau kev tsim kho hauv cov teb chaws xws li Tebchaws Meskas suav txog ib nrab ntawm tag nrho cov khoom siv ua npuas ncauj, uas yog ntau tshaj li ob npaug ntawm kev noj cov npuas dej khov xws li cov tub yees thiab lub tub yees. Ntau lub teb chaws hauv ntiaj teb muaj cov kev cai meej ntawm kev siv hluav taws xob hauv kev tsim vaj tsev, uas txhawb nqa kev siv cov npuas tawv tawv hauv kev tsim vaj tsev.
Kev siv txhua xyoo ntawm polyurethane ua npuas ncauj rau kev tsim kho hauv Tebchaws Meskas yog kwv yees li 300, 000 tons, suav txog 65% ntawm kev tsim ua npuas ua lag luam (qhov seem yog polystyrene thiab phenolic ua npuas ncauj), thiab suav txog li 50% ntawm tag nrho PU tawv ua npuas ncauj.
Nyob rau hauv kuv lub teb chaws, rigid ua npuas ncauj tau lug siv nyob rau hauv thermal rwb thaiv tsev thiab waterproofing ntawm lub ru tsev ntawm cov tsev nyob thiab chaw ua hauj lwm, thermal rwb thaiv tsev ntawm phab ntsa, thiab thermal rwb thaiv tsev cov ntaub ntawv nyob rau hauv txias cia, grain depots, thiab lwm yam. ru tsev, ntxiv rau cov txheej txheem tiv thaiv, uas muaj ob qho kev cuam tshuam ntawm thermal rwb thaiv tsev thiab waterproofing.
Cov hlau-ntsej muag nruj polyurethane sandwich vaj huam sib luag yog ua los ntawm cov nplaim hluav taws kub nyhiab polyurethane ua npuas ncauj (muab faib ua ob hom qauv sib txawv, PU thiab PIR) ua cov khoom tseem ceeb, nrog cov xim-coated steel daim hlau raws li cov khoom siv saum npoo av, thiab txuas ntxiv tsim los ntawm PU. los yog PIR foaming Thiab, tseem hu ua composite panels. Nws ua ke lub teeb yuag, siab zog, rwb thaiv tsev kub, waterproofing thiab kho kom zoo nkauj. Nws yog cov khoom siv ntau lub tsev tshiab uas yooj yim tsim, tsim thiab nruab.
Tam sim no, domestic hlau-ntsej muag nruj polyurethane sandwich panels yog dav siv nyob rau hauv industrial cov nroj tsuag, warehouses, sports venues, tsev nyob, villas, prefabricated tsev, modular txias cia thiab lwm lub tsev, thiab yog siv raws li ru tsev panels thiab phab ntsa panels. Vim nws lub teeb yuag, thermal rwb thaiv tsev, tsis muaj dej, kho kom zoo nkauj thiab lwm yam ntxwv, kev thauj mus los yooj yim (kev teeb tsa) thiab kev tsim kho sai, nws yog qhov nrov heev ntawm cov neeg tsim qauv, kev tsim kho thiab cov tsim tawm.
Polyurethane txhav ua npuas ncauj yog ntim rau hauv hollow cib, uas tuaj yeem ua rau hauv cov npuas dej uas muaj cov hollow cib uas muaj cov thermal rwb thaiv tsev zoo. Nws tseem tuaj yeem ua rau hauv polyurethane txhav ua npuas ncauj. Qhov ntom ntawm cov pob zeb no yog kwv yees li 200kg / m3, lub zog compressive yog 0.59 ~ 0.78MPa, thiab thermal conductivity yog li 64mW / (m·K). Nws tuaj yeem ua rau lub tsev loj loj.
Polyurethane rigid foam boards tuaj yeem ua rau ntau lub tsev txawb txawb, uas tuaj yeem siv ua tsev nyob ib ntus hauv cov tsiaj qus. Piv txwv li, yog tias qhov saum npoo ntawm 10 hli tuab polyurethane txhav ua npuas ncauj npog nrog polyethylene, nws tuaj yeem ua rau hauv lub tsev folding, los yog cov tshuaj tsuag-coated polyurethane rigid ua npuas ncauj yuav siv tau los ua ib lub polyurethane rigid foam spherical ib ntus.
Cov chaw txuag dej xws li cov pob zeb ua vaj tse yuav tsum tau ntsuas kev tiv thaiv thaum lub caij ntuj no txias. polyurethane txhav ua npuas ncauj tuaj yeem txau rau saum npoo ntawm cov pob zeb tshiab ua ib txheej rwb thaiv tsev. Nyob rau hauv qhov chaw txias heev, polyurethane rwb thaiv tsev boards tuaj yeem siv los ua cov khoom tiv thaiv khov rau cov kab hauv ob sab phlu kom txo tau qhov kev puas tsuaj los ntawm te heave rau cov ntaub ntawv hauv ob sab phlu thiab xyuas kom ruaj ntseg ntawm cov hauv ob sab phlu thiab siv cov kev nyab xeeb.
