PU thiab PIR polyurethanecia khoom txiasCov vaj huam sib luag tau lees paub dav dav tias yog cov khoom siv rwb thaiv tsev zoo tshaj plaws rau kev tsim kho chaw cia khoom txias niaj hnub no. Lawv cov thermal conductivity qis heev thiab kev ruaj khov zoo heev ua rau lawv yog qhov kev daws teeb meem zoo tshaj plaws rau cov chaw cia khoom txias nruab nrab thiab loj.
Nrog kev siv cov polyurethane panels loj heev, cov txheej txheem logistics txias niaj hnub tau txhim kho qhov zoo ntawm kev khaws cia thaum txo cov nqi khiav lag luam tag nrho. Cov panels no tam sim no ua lub luag haujlwm tseem ceeb hauv kev siv hluav taws xob tsawg hauv cov khoom noj, tshuaj, thiab kev lag luam.
Kev Ua Tau Zoo Tshaj Plaws ntawm Polyurethane Cold Storage Panels
Qhov zoo tshaj plaws ntawm kev sib tw ntawm cov vaj huam sib luag polyurethane txias cia yog nyob rau hauv lawv cov qauv kaw-cell microstructure sab hauv. Cov qauv kev lag luam xav tau cov vaj huam sib luag polyurethane zoo kom ua tiav qhov nqi kaw-cell ntawm ntau dua 95 feem pua. Tus neeg sawv cev ua npuas ncauj tsim cov qhov me me kaw hauv cov khoom siv tseem ceeb, thiab cov qhov no zoo thaiv cov kev hloov pauv cua sov. Yog li ntawd, kev sib pauv thermal ntawm sab hauv thiab sab nraud ntawm qhov chaw cia khoom txias tseem qis heev.
Ua tsaug rau qhov sib piv ntawm lub cell kaw no, cov vaj huam sib luag polyurethane feem ntau ncav cuag qib thermal conductivity ntawm 0.018 thiab 0.024 W / m · K. Cov ntaub ntawv rwb thaiv tsev ib txwm muaj xws li cov laug cam pob zeb lossis cov vaj huam sib luag EPS polystyrene feem ntau qhia cov nqi thermal conductivity ntawm 0.035 thiab 0.045 W / m · K. Raws li cov kev cai rwb thaiv tsev tib yam, cov vaj huam sib luag polyurethane tuaj yeem ua tiav qhov kev ua tau zoo nrog yuav luag ib nrab ntawm cov tuab ntawm cov ntaub ntawv ib txwm muaj. Qhov zoo no ncaj qha txo qhov chaw siv hauv tsev thiab txhim kho qhov ntim cia khoom siv tau.
Cov vaj huam sib luag polyurethane txias cia kuj sib npaug kev ua tau zoo ntawm kev rwb thaiv tsev nrog lub zog kho tshuab los ntawm kev tswj cov khoom siv ceev. Cov vaj huam sib luag zoo tshaj plaws feem ntau tswj tau qhov ceev ntawm kev ua npuas dej ntawm 38 thiab 40 kg / m³. Qhov ntau no sawv cev rau qhov sib npaug zoo tshaj plaws ntawm kev ruaj khov ntawm cov qauv thiab kev ua haujlwm thermal. Qhov ceev qis dua ua rau lub zog compressive tsis muaj zog thiab ua rau muaj kev pheej hmoo deformation. Qhov ceev siab dua ua rau muaj kev coj ua thermal thiab tus nqi khoom siv yam tsis muab cov txiaj ntsig sib piv.
Cov Lus Qhia Txog Kev Siv Tshuab thiab Cov Xwm Txheej Siv
Feem ntau cov chaw tsim khoom tsim cov vaj huam sib luag polyurethane txias cia los ntawm kev sib txuas cov ua npuas ncauj polyurethane tawv ntawm ob txheej ntawm cov hlau uas tau pleev xim ua ntej. Cov qauv sib xyaw no muab ob qho tib si rwb thaiv tsev thiab qhov ruaj khov ntawm qhov chaw. Kev xaiv tuab ntawm vaj huam sib luag ua raws li cov lus qhia nruj raws li qhov kub thiab txias.
Cov vaj huam sib luag uas muaj tuab li ntawm 50 txog 100 hli haum rau cov chaw khaws khoom tshiab saum 0°C. Cov chav cia khoom txias uas ua haujlwm ib puag ncig -18°C feem ntau xav tau cov vaj huam sib luag uas tuab li ntawm 100 txog 150 hli. Rau cov chaw khaws khoom khov sai lossis cov chaw kub qis heev hauv qab -25°C, cov kws ua vaj huam sib luag feem ntau teev cov vaj huam sib luag tuab li ntawm 150 txog 200 hli. Cov kev teeb tsa no ua kom muaj qhov kub thiab txias sab hauv ruaj khov thiab tiv thaiv kev poob zog ntau dhau.
Lub zog compressive tseem yog lwm qhov tseem ceeb hauv kev tsim cov khoom siv cia khoom txias. Cov vaj huam sib luag yuav tsum txhawb nqa cov khoom thauj los ntawm cov txee, cov evaporators, thiab lwm yam khoom siv uas tau teeb tsa. Cov vaj huam sib luag cia khoom txias polyurethane zoo feem ntau ua tiav cov nqi zog compressive siab dua 150 kPa. Qib no ua kom ntseeg tau tias cov qauv tsim tau ntev thaum lub sijhawm ua haujlwm tas mus li.
Kev nyab xeeb hluav taws kuj cuam tshuam rau kev xaiv cov khoom siv. Feem ntau cov vaj huam sib luag polyurethane txias cia khoom siv ua tau raws li cov qauv tiv thaiv hluav taws B1 lossis B2. Cov ntaub ntawv qib B1 tua nws tus kheej hauv peb vib nas this tom qab tshem tawm hluav taws. Cov ntaub ntawv qib B2 tua nws tus kheej hauv peb txog rau vib nas this. Cov yam ntxwv no txo cov kev pheej hmoo ntawm kev kis hluav taws thiab txhim kho kev nyab xeeb ntawm qhov chaw.
Kev ruaj khov ntawm cov khoom siv ntxiv ua rau cov vaj huam sib luag zoo sib txawv. Cov vaj huam sib luag polyurethane txias feem ntau tswj cov dej nqus hauv qab 1 feem pua. Lawv kuj ua haujlwm tau zoo thoob plaws ntau qhov kub ntawm -60 ° C txog + 120 ° C. Qhov kev ruaj khov no ua kom muaj kev ua haujlwm rwb thaiv tsev zoo ib yam hauv qab kev ua haujlwm hnyav thiab kev hloov pauv kub ntau zaus.
Cov Kev Zoo ntawm Cov Qauv: Kev Siv Tshuab Txuas Lus Uas Tau Pom Zoo
Cov choj txias yog ib qho ntawm cov kev hem thawj loj tshaj plaws rau kev ua haujlwm ntawm kev khaws cia txias. Cov vaj huam sib luag polyurethane khaws cia txias daws qhov teeb meem no los ntawm kev sib txuas lus ntawm tus nplaig thiab qhov zawj ua ke nrog cov txheej txheem xauv eccentric uas ua rau hauv. Cov kab ke no tso cai rau cov vaj huam sib luag kom haum ua ke thiab tsim ib txheej rwb thaiv tsev tas mus li.
Qhov kev tsim qauv no ua kom muaj kev ua haujlwm zoo heev ntawm kev sib khi. Thaum cov neeg teeb tsa ntxiv cov ntawv nplaum thiab cov khoom ua npuas dej, qhov xau cua thiab kev poob txias ntawm cov pob qij txha poob qis mus rau qib tsawg kawg nkaus. Rau qhov chaw cia khoom txias uas npog kwv yees li 1,000 square meters, cov vaj huam sib luag polyurethane zoo tuaj yeem txo qhov kev siv hluav taws xob txhua xyoo los ntawm kwv yees li 20 txog 30 feem pua piv rau cov ntaub ntawv rwb thaiv tsev ib txwm muaj. Qhov kev txo qis no txhais tau tias muaj txiaj ntsig zoo rau kev lag luam mus sij hawm ntev thiab rov qab los ntawm kev nqis peev sai dua.
