Cov nyhuv ntawm cov xim hlau pobzeb thermal rwb thaiv tsev xim yog dab tsi? Yuav tsim li cas?

Nyob rau lub caij ntuj sov thaum huab cua sov thiab kub nce, cov xim hlau vuas tuaj yeem yooj yim cua sov mus rau ntau tshaj 60 degrees hauv qab tshav ntuj ncaj qha. Cov kub kub zoo li no yuav ua rau chav tsev nyob rau hauv cov xim steel pobzeb ru tsev kub heev, txawm tias koj nyob lossis ua haujlwm hauv nws. Nws yuav ua rau muaj kev tsis xis nyob. Yog li ntawd, nws yog ib qho tseem ceeb rau insulate cov xim hlau vuas kom txo qhov kub ntawm cov xim hlau pobzeb ru tsev thiab muab ib qho chaw zoo nyob hauv tsev!
Yog li, puas muaj ib txoj hauv kev yooj yim thiab zoo rau insulate xim steel vuas?
Tau kawg muaj, koj tsuas yog yuav tsum tau thov ib txheej xim hlau pobzeb thermal rwb thaiv tsev xim. Tam sim no peb to taub yuav ua li cas xim hlau pobzeb thermal rwb thaiv tsev xim ua tiav cov nyhuv tshav kub?
Nws lub hauv paus ntsiab lus yog txo qhov nqus ntawm lub zog hluav taws xob los ntawm kev xav txog hnub ci. Thermal rwb thaiv tsev xim muaj siab reflectance, ze-infrared reflectance thiab tsawg hemispheric emissivity. Raws li peb cov ntaub ntawv xeem, qhov cuam tshuam ntawm cov xim rwb thaiv tsev tuaj yeem ncav cuag 85%, qhov ze-infrared reflectance yog 87%, thiab hemispheric emissivity yog 89%. Cov lus piav qhia nrov yog tias 85% ntawm lub hnub pom lub teeb pom kev zoo thiab 87% ntawm lub teeb pom kev (ze-infrared teeb) yog reflected. Cov xim pleev xim rau cov cua sov no muaj lub peev xwm tso tawm kom sov thiab tso tawm 89% ntawm lub zog cua sov. Cov ntaub ntawv no txhais tau hais tias qhov kub ntawm cov xim hlau vuas uas tsis muaj cov xim kub-insulating tuaj yeem ncav cuag 60 degrees, thaum qhov kub ntawm cov xim hlau vuas nrog cov xim kub-insulating tuaj yeem ruaj khov nyob ib ncig ntawm 35 degrees. Qhov ntsuas kub no txo ​​qis tsis yog tsuas yog ua rau sab hauv tsev kub hauv qab lub ru tsev zoo nkauj dua, tab sis kuj txo qis kev siv cua txias lossis cua txias, yog li txuag lub zog. Los ntawm cov ntaub ntawv saum toj no, peb tuaj yeem pom qhov tseeb tias cov hluav taws kub rwb thaiv tsev ntawm cov xim hlau pobzeb rwb thaiv tsev xim yog qhov zoo heev.
Yog li, dab tsi yog txoj kev tsim kho ntawm cov xim hlau pobzeb rwb thaiv tsev xim?
Ua ntej ntawm tag nrho cov, xyuas kom meej qhov chaw ntawm cov xim hlau pobzeb yog huv si. Kev ntxuav lub ntsej muag tuaj yeem tshem tawm cov plua plav, roj thiab lwm yam khoom paug thiab muab cov txheej txheem zoo.
Tom ntej no, sib tov cov xim hlau pobzeb kub-insulating xim. Cov xim kub-insulating no yog dej-raws li, tsis muaj ntxhiab, thiab yooj yim rau kev khiav lag luam. Tom qab tau txais cov xim hluav taws kub-insulating, ncaj qha ntxiv 20-30% dej kom dilute nws. Nyob ntawm qhov viscosity ntawm cov xim kub-insulating, dilute nws mus rau lub xeev uas yooj yim rau kev tsim kho, thiab ua tiav tam sim Nws muaj qee yam fluidity thiab tuaj yeem ua tiav cov txheej txheem zoo.
Txoj kev tsim kho tuaj yeem yog txhuam ncaj qha, cov menyuam txheej lossis txau. Xaiv txoj kev tsim nyog rau kev tsim kho raws li qhov xwm txheej tshwj xeeb. Txij li thaum kev tsim kho yog tshwj xeeb yog yooj yim, kuv yuav tsis mus rau hauv cov ntsiab lus ntawm no. Txhua tus uas muaj kev paub txog kev pleev xim tuaj yeem pib ncaj qha. Feem ntau hais lus, lub sijhawm ziab ntawm cov xim kub-insulating yog li 55 feeb. Tom qab tos kom qhuav, koj tuaj yeem hnov ​​​​qhov pom tseeb thaum tshav kub kub-insulating nyhuv.
Ntxiv nrog rau cov nyhuv thermal rwb thaiv tsev, xim hlau pobzeb thermal rwb thaiv tsev xim kuj muaj lwm yam zoo. Ua ntej tshaj plaws, nws muaj cov khoom siv dej tsis zoo thiab hnav-tiv taus, uas tuaj yeem tiv thaiv kom tsis txhob xau thiab kev puas tsuaj ntawm cov xim hlau vuas thiab txuas ntxiv lawv lub neej kev pabcuam. Thib ob, cov xim kub-insulating feem ntau siv cov qauv dej, uas yog ib puag ncig tus phooj ywg, tsis muaj ntxhiab, tsis muaj mob rau tib neeg kev noj qab haus huv, thiab ib puag ncig zoo. Tsis tas li ntawd, cov xim hlau pobzeb thermal rwb thaiv tsev xim muaj cov adhesion zoo thiab tuaj yeem txuas rau ntawm cov xim hlau pobzeb thiab tsis yooj yim rau tev lossis poob, muab kev tiv thaiv ntev.
Yuav kom suav tau, raws li cov khoom siv hluav taws xob zoo, cov xim hlau pobzeb rwb thaiv tsev xim muaj cov thermal rwb thaiv tsev zoo heev. Nws tuaj yeem txo qhov kub ntawm cov xim hlau pobzeb lub ru tsev thiab muab qhov chaw zoo nyob sab hauv tsev. Los ntawm kev xav txog lub hnub ci thiab txo cov cua sov lub zog nqus, thermal rwb thaiv tsev xim tuaj yeem txo qhov kub ntawm cov xim hlau vuas. Thaum lub sij hawm tsim kho, ntxuav cov xim hlau vuas luaj, npaj cov xim pleev xim rau cov cua sov uas tsim nyog, thiab siv nws los ntawm txhuam, cov menyuam txheej los yog tshuaj tsuag. Tom qab ziab, koj tuaj yeem tau txais kev pom tseeb thaum tshav kub kub-insulating teebmeem. Tsis tas li ntawd, thermal rwb thaiv tsev xim kuj muaj qhov zoo ntawm cov dej tsis zoo thiab hnav-tiv taus, ib puag ncig tus phooj ywg, tsis muaj ntxhiab thiab muaj zog adhesion. Yog li ntawd, xim hlau pobzeb rwb thaiv tsev xim yog ib qho kev xaiv tsim nyog xav txog, uas tuaj yeem muab kev tiv thaiv zoo rau cov xim hlau pobzeb ru tsev thiab txhim kho kev nplij siab hauv tsev.
