Raws li cov kab mob khaub thuas logistics thiab kev txuag zaub mov kev lag luam sai sai, kev xaiv ntawm rwb thaiv tsev sandwich panels rau txias cia yog qhov tseem ceeb. Tam sim no, muaj ob yam tseem ceeb ntawm kev cia txias rwb thaiv tsev sandwich panels ntawm lub khw: Polyurethane sandwich panels, AKA PU lossis puf sandwich panels thiab Expanded Polystyrene (EPS) sandwich panels. Peb yuav sib piv qhov zoo thiab qhov tsis zoo ntawm ob cov ntaub ntawv hauv kev nthuav dav raws li kev lag luam tiam sis xyoo dhau los.
Qhov zoo ntawmpuv panel rau cqubchav
1. Kev ua tau zoo ntawm rwb thaiv tsev: PU txias cia sandwich panels los yog puf vaj huam sib luag rau chav txias yog renowned rau lawv superior rwb thaiv tsev kev ua tau zoo. Lawv cov thermal conductivity yog tsawg, ntawm li {{0}}.024 W/m·K, piv rau EPS panels '0.039 W/m·K. Qhov qis thermal conductivity no txhais tau hais tias kev rwb thaiv tsev zoo dua, pab txo qis kev siv hluav taws xob ntawm kev cia txias thiab txo cov nqi khiav lag luam.
2. Lub zog muaj zog: PU txias cia sandwich panels lossis puf vaj huam sib luag rau chav txias feem ntau muaj qhov ceev ntawm 40-42 kg/m³, ntau dua li EPS panels ' 20-30 kg/m³. Qhov no muab PU txias cia panels siab dua txhua yam muaj zog thiab zoo compressive kev ua tau zoo, ua rau lawv ntau ruaj thiab ntev-ntev nyob rau hauv txias cia tsim.
3. Kev ua tau zoo tua hluav taws: Niaj hnub nimno PU txias cia vaj huam sib luag los yog puf vaj huam sib luag rau chav txias feem ntau siv cov nplaim hluav taws kub nyhiab, ua tiav B1 lossis qib B hauv UL 723 tus qauv (tsis tshua muaj nplaim taws) qhov ntsuas hluav taws kub, qhov txheej txheem EPS panels muaj hluav taws tsis zoo, tsuas yog ncav cuag B3 lossis Ua tsis tiav hauv UL 723 tus qauv (flammable) ntsuas. Qhov ntsuas hluav taws kub siab dua ntawm PU cov chaw cia txias txias muab kev nyab xeeb dua, tshwj xeeb tshaj yog nyob rau hauv qhov chaw txias txias nrog cov kev cai tiv thaiv hluav taws nruj heev.
PU Sandwich vaj huam sib luag EPS
Qhov zoo ntawm EPS Txias Cia Vaj Huam Sib Luag
Tus nqi qis dua: EPS sandwich panels muaj nqi ntau lawm, ua rau lawv cov nqi lag luam kuj pheej yig dua. Qhov no yog ib qho kev txiav txim siab tseem ceeb rau kev tsim kho cov dej txias nrog cov peev nyiaj tsawg.
Kev lag luam Trend Analysis
Nyob rau hauv lub xyoo caum dhau los, nrog rau kev nce hauv kev txuag hluav taws xob, txo qis emissions, thiab kev paub txog ib puag ncig, PU txias cia vaj huam sib luag lossis puf vaj huam sib luag rau chav txias tau maj mam ua lag luam loj dua. Lawv cov rwb thaiv tsev zoo heev thiab kev pab cuam lub neej ntev ua rau PU txias cia sandwich panels zoo heev hauv kev siv hluav taws xob thiab kev tswj tus nqi mus sij hawm ntev. Tsis tas li ntawd, nrog rau kev txhim kho thev naus laus zis, cov txheej txheem tsim khoom ntawm PU txias cia sandwich panels tau raug txhim kho tas li, txo cov nqi tsim khoom thiab ntxiv dag zog rau lawv cov kev sib tw ua lag luam.
Tsis tas li ntawd, cov qauv thiab cov cai tswj kev nyab xeeb rau kev tsim kho qhov txias txias tau dhau los ua nruj dua nyob rau xyoo tas los no, tshwj xeeb tshaj yog hais txog kev nyab xeeb hluav taws. Kev ua tau zoo ntawm cov hluav taws kub zoo ntawm PU txias cia sandwich panels ua rau lawv muaj txiaj ntsig zoo hauv kev ua tau raws li cov qauv tshiab no, uas yog qhov tseem ceeb ua rau lawv txoj kev lag luam loj hlob.
Xaus
Hauv cov ntsiab lus, txawm hais tias EPS txias cia vaj huam sib luag muaj qee qhov zoo ntawm cov nqi thiab kev yooj yim ntawm kev teeb tsa, PU txias cia sandwich panels sawv hauv qhov chaw txias cia nrog lawv cov rwb thaiv tsev zoo dua, kev ua haujlwm siab dua, thiab kev ua haujlwm zoo heev. Xav txog kev lag luam tiam sis, PU txias cia sandwich panels muaj kev lag luam zoo dua yav tom ntej, tshwj xeeb tshaj yog nyob rau hauv kev tsim kho txias txias niaj hnub uas hais txog kev siv hluav taws xob thiab kev nyab xeeb, lawv cov txiaj ntsig yuav ua kom pom tseeb dua.
