Txawm hais tias qhov zoo ntawm cov tshuab cua txias ua tau raws li tus qauv tsim nyog, qhov tseem ceeb nyob ntawm seb qhov zoo ntawm cov rwb thaiv tsev puas tau raws li tus qauv tsim nyog (zoo heev). Qhov zoo ntawm rwb thaiv tsev tsis tsuas yog nyob ntawm theem ntawm kev tsim cov rwb thaiv tsev, tab sis kuj nyob ntawm kev xaiv cov khoom siv cua txias rwb thaiv tsev yeeb nkab. Nyob rau hauv xyoo tas los no, ntau yam ntawm cov cua txias rwb thaiv tsev yeeb nkab cov ntaub ntawv yog nce, thiab ntau yam kev xaiv kuj nce. Kev sib txawv ntawm cov khoom siv ntau yam ua rau muaj kev sib txawv ntawm cov ntsuas kev ua tau zoo. Hnub no tsab xov xwm tsom mus rau nam ntawm foamed yas khoom.
Foamed yas khoom
Foamed yas khoom (xws li polyethylene, polyurethane, polystyrene) muaj lub teeb yuag thiab tsawg ntom; Lub thermal conductivity yog me me, nyob ntawm qhov kub thiab txias. Qhov siab tshaj plaws siv kub ntawm cov khoom yog qis dua 100 ° C, feem ntau tsis ntau tshaj 70 ° C; Kev nqus dej tsawg, nrog cov dej tsis muaj zog. Cov khoom siv feem ntau yog siv nyob rau hauv sub-zero low temperature cool preservation projects xws li oxygen ntau lawm, rwb thaiv tsev tub yees thiab lwm yam. Txhawm rau ua kom tau raws li cov cai ntawm kev tiv thaiv hluav taws hauv tsev, cov tuam txhab tsim tshwj xeeb tsim tus kheej-flameproof B1 qib ua npuas ncauj yas xws li polyethylene rau lub tsev cua txias system rwb thaiv tsev engineering. Polyethylene rwb thaiv tsev cov ntaub ntawv muaj ib tug zoo ywj siab npuas qauv, elastic, yooj yim ua, yuav arbitrarily txiav, yooj yim rau haum thiab tsis tshua muaj dej nqus. Yog li nws yog tsim nyog rau cua txias chilled dej yeeb nkab system rwb thaiv tsev. Nyob rau hauv lub tshuab cua txias, polyethylene kuj tseem siv tau los ua cov khoom siv rwb thaiv tsev, tshwj xeeb tshaj yog cov cua txias uas yuav tsum tau ua kom huv si, thiab cov khoom siv rwb thaiv tsev ntawm cov yeeb nkab tsis pub siv cov ntaub ntawv xws li iav ntaub plaub uas yooj yim los tsim fiber ntau. chips, yog li tus nqi nruab nrab ntawm polyethylene yog ib qho kev hloov zoo.
Nyob rau hauv cov nqe lus ntawm kev ua lag luam mov, ntau manufacturers tau muab tso rau hauv ntau lawm, thiab kev ua lag luam kev sib tw yog nruj heev. Qee lub npe nrov nrog cov thev naus laus zis siab thiab cov khoom siv zoo, tsim cov rwb thaiv tsev zoo thiab cov khoom siv ruaj khov, tuav lub lag luam loj dua. Txawm li cas los xij, qee cov tuam txhab me me txhawm rau txo cov nqi, kev siv cov khoom siv tsis zoo, cov khoom lag luam tsis sib xws.
Nrog rau kev loj hlob zuj zus ntawm Tuam Tshoj txoj kev lag luam, tam sim no, tib neeg muaj kev xav tau ntau dua thiab siab dua rau kev nplij siab ntawm kev ua haujlwm thiab kev nyob ib puag ncig, qhov kev thov rau cov cua txias hauv nruab nrab tau loj hlob, thiab ntau dua kev saib xyuas yog them rau cov cua txias zog txuag, kev nplij siab thiab kev noj qab haus huv. Lub tshuab cua txias tau dhau los ua ib lub cim tseem ceeb ntawm cov cuab yeej siv niaj hnub no, thiab nws tseem yog ib qho tseem ceeb hauv kev tsim kho vaj tse niaj hnub los tsim kom muaj kev ua haujlwm zoo thiab ua haujlwm zoo thiab nyob ib puag ncig. Nyob rau hauv kev sib piv ntawm lub tsev txuag hluav taws xob thiab lub tsev ntsuab, kev lag luam cua txias hauv tsev tau ntsib txoj hauv kev zoo thiab cov teeb meem. Cov tsev loj loj, cov chaw lag luam CBD, cov khw muag khoom, cov khw muag khoom loj, cov vaj tsev pej xeem thiab lwm lub tsev muaj kev txuag hluav taws xob ntau ntxiv rau cov tshuab cua txias.
Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho ntawm kev tiv thaiv ib puag ncig thiab kev ua tiav ntawm kev siv thev naus laus zis, cov cua txias rwb thaiv tsev yeeb nkab kev lag luam yuav txhim kho nyob rau hauv kev coj ua kom muaj txiaj ntsig zoo, kev tiv thaiv ib puag ncig thiab txuag hluav taws xob. Cov tuam txhab lag luam yuav tsum tau hloov kho tshiab thiab txhim kho cov khoom zoo thiab kev ua tau zoo kom hloov mus rau kev hloov pauv hauv kev lag luam thiab kev xav tau.
Kev lag luam kev cia siab ntawm cov cua txias rwb thaiv tsev yeeb nkab yog dav, tab sis kuj muaj tag nrho cov kev cov nyom, tsuas yog los ntawm kev hloov mus tas li rau kev hloov pauv hauv kev lag luam, txhawm rau kom sawv tawm hauv kev sib tw hnyav.
