Cov rwb thaiv tsev puas tuaj yeem kov cov xov hlau hluav taws xob?
Txheem
Feem ntau cov tsev muaj thermal rwb thaiv tsev nyob rau hauv lub qab nthab, lub ru tsev, los yog lub qab nthab thiab qhov no yog ib txoj hauv kev zoo los txo cov cua sov. Kev poob qis dua txhais tau tias cov nqi hluav taws xob qis dua. Tab sis yog tias koj txhawj xeeb txog kev kov cov hluav taws xob thaiv hluav taws xob, koj tsis nyob ib leeg. Thaum kuv pib kuv txoj hauj lwm ua ib tug hluav taws xob, kev nyab xeeb yog ib qho ntawm thawj yam kuv kawm. Cov rwb thaiv tsev puas tuaj yeem kov cov xov hlau hluav taws xob? Nov yog qee qhov kev xav ntawm qhov no los ntawm kuv tus kheej kev paub.
Feem ntau, kov lub thermal rwb thaiv tsev rau cov xov hlau tsis muaj kev phom sij, vim tias cov xov hlau yog hluav taws xob rwb thaiv tsev. Nyob ntawm seb hom rwb thaiv tsev thermal, koj tuaj yeem siv ntau txoj hauv kev ntawm kev tso ib ncig ntawm lub rwb thaiv tsev. Txawm li cas los xij, tsis txhob cia thermal rwb thaiv tsev los rau hauv kev sib cuag nrog uninsulated nyob hlau.
Yuav ua li cas thermal rwb thaiv tsev tiv thaiv hluav taws xob thaiv?
Cov kab hluav taws xob niaj hnub no yog insulated kiag li. Qhov kev sib cais hluav taws xob tiv thaiv tam sim no tsis txhob ncav cuag lwm qhov chaw hauv koj lub tsev. Nyob rau hauv txoj kev no, cov xaim kub tuaj yeem kov cov thermal rwb thaiv tsev.
Yam koj yuav tsum paub txog hluav taws xob rwb thaiv tsev
Cov hluav taws xob rwb thaiv tsev yog ua los ntawm cov khoom siv tsis zoo. Yog li ntawd, cov insulators no tsis dhau hluav taws xob tam sim no. Feem ntau, cov chaw tsim khoom siv ob yam khoom siv rau cov khoom siv hluav taws xob hauv tsev; thermoplastic thiab thermosetting. Nov yog qee cov ntsiab lus hais txog ob yam khoom no.
thermoplastic
Thermoplastic yog cov khoom siv polymer. Raws li qhov kub thiab txias, cov khoom no melts thiab ua haujlwm tau. Nws kuj hardens thaum nws txias. Feem ntau, cov thermoplastic muaj qhov hnyav dua molecular. Koj tuaj yeem yaj thiab kho cov thermoplastic ob peb zaug. Txawm li cas los xij, cov yas tsis plam nws txoj kev ncaj ncees thiab lub zog.
KOJ PUAS POM: Kev ua haujlwm siab thermoplastic pib yaj ntawm 6500 ° F thiab 7250 ° F. Peb tsis siv cov thermoplastics uas ua tau zoo no los tsim cov hluav taws xob thaiv hluav taws xob.
Muaj tsib lub thermoplastics uas yog siv los ua cov khoom siv hluav taws xob insulating. Ntawm no yog tsib lub thermoplastics.
| Thermoplastic hom | Melting kub |
| Polyvinyl chloride | 212 - 500 ° F |
| Polyethylene (PE) | 230 - 266 ° F |
| nylon | 428 ° F yog |
| ECTEF | 464 ° F yog |
| PVDF | 350 ° F yog |
ntsuas kub
Cov yas thermoset yog tsim los ntawm cov kua dej khov thiab cov txheej txheem kho tuaj yeem ua tiav ntau txoj hauv kev. Cov neeg tsim khoom siv cov kua dej catalytic, hluav taws xob ultraviolet, kub kub lossis kub siab rau cov txheej txheem kho.
Nov yog qee yam hom thermoset plastics.
- XLPE (XLPE)
- Chlorinated polyethylene (CPE)
- Ethylene propylene roj hmab (EPR)
Hom thermal rwb thaiv tsev
Muaj plaub hom kev rwb thaiv tsev feem ntau pom hauv Asmeskas. Nyob ntawm cov cua kub ntawm lub tsev thiab hom kev tsim kho, koj tuaj yeem xaiv cov rwb thaiv tsev.
Kev rwb thaiv tsev ntau
Cov rwb thaiv tsev feem ntau muaj cov ntaub ntawv tsis sib xws. Piv txwv li, koj tuaj yeem siv fiberglass, ntxhia wool lossis Icynene. Koj tuaj yeem siv cellulose lossis perlite.
TSWV YIM: Cellulose thiab perlite yog cov khoom siv ntuj.
Ntxiv cov ntaub ntawv rau hauv qab nthab, hauv pem teb, lossis cov phab ntsa uas nyob ib sab los txhim kho cov rwb thaiv tsev ntau. Thaum xaiv cov khoom siv hluavtaws rau cov rwb thaiv tsev ntau, nco ntsoov xyuas tus nqi R.Qhov no yuav txawv nyob ntawm qhov kub ntawm koj cheeb tsam.
Koj puas paub: Tej fiberglass rwb thaiv tsev tuaj yeem ignite ntawm 540 ° F.
Daim pam rwb thaiv tsev
Ib daim pam rwb thaiv tsev yog ib qho zoo heev rau qhov chaw nruab nrab ntawm uprights. Lawv muaj cov ntawv tuab tuab uas tuaj yeem siv los sau qhov chaw ntawm racks lossis lwm qhov chaw zoo sib xws. Feem ntau, cov pam vov no yog 15 txog 23 ntiv tes dav. Thiab muaj lub thickness ntawm 3 mus rau 10 ntiv tes.
Raws li cov rwb thaiv tsev ntau, cov rwb thaiv tsev saum npoo yog tsim los ntawm fiberglass, cellulose, ntxhia wool, thiab lwm yam. Nyob ntawm cov khoom siv rwb thaiv tsev, nws yuav kub hnyiab ntawm 1300 ° F thiab 1800 ° F.
Rigid ua npuas ncauj rwb thaiv tsev
Hom rwb thaiv tsev no yog tshiab rau cov tsev nyob thermal rwb thaiv tsev. Rigid foam rwb thaiv tsev yog thawj zaug siv hauv xyoo 1970s. Nws los nrog polyisocyanurate, polyurethane, ntxhia ntaub plaub thiab fiberglass vaj huam sib luag.
Cov ntaub nplaum nplaum nplaum no yog 0.5 "mus rau 3" tuab. Txawm li cas los xij, yog tias tsim nyog, koj tuaj yeem yuav lub vaj huam sib luag 6-nti. Tus qauv vaj huam sib luag loj yog 4 ko taw los ntawm 8 ko taw. Cov panels no haum rau cov phab ntsa tsis tiav, qab nthab thiab hauv qab daus. Polyurethane panels ignite ntawm qhov kub ntawm 1112 ° F txog 1292 ° F.
Ua npuas ncauj rwb thaiv tsev nyob rau hauv qhov chaw
Foamed-in-qhov chaw rwb thaiv tsev kuj tseem hu ua cov tshuaj tsuag npuas rwb thaiv tsev. Hom rwb thaiv tsev no muaj ob hom tshuaj sib xyaw. Qhov sib tov yuav nce 30-50 zaug piv rau qhov qub ntim ua ntej qhov txheej txheem kho pib.
Foamed-hauv-qhov chaw rwb thaiv tsev feem ntau yog tsim los ntawm cellulose, polyisocyanurate, los yog polyurethane. Koj tuaj yeem nruab cov rwb thaiv tsev no hauv qab nthab, phab ntsa tsis tiav, cov plag tsev thiab ntau lwm qhov nyuaj mus txog qhov chaw. Ntawm 700˚F, ua npuas ncauj rwb thaiv tsev ignites.
