Kev Txhaj Tshuaj Polyurethane Ntawm Cov Thawv Uas Tau Thermally Insulated?

Hom tsev ntim khoom feem ntau yog muab vaj tse rau cov neeg ua haujlwm ntawm qhov chaw tsim kho.Lawv puas tuaj yeem nyob hauv lub caij ntuj sov lossis lub caij ntuj no txias?Nws yuav tsis txias los yog kub?Qhov tseeb, txawm tias nws yog lub caij ntuj sov lossis lub caij ntuj no, cov thawv tuaj yeem raug insulated.Yog tias koj tsis ntseeg kuv, nyeem ntxiv!

Lub thawv nws tus kheej tsis muaj kev ua haujlwm ntawm thermal rwb thaiv tsev.Nws yog txias nyob rau hauv lub caij ntuj no thiab kub nyob rau hauv lub caij ntuj sov.Nyob rau lub caij ntuj sov, qhov kub ntawm sab nraum zoov yog 38 °, thiab qhov kub hauv lub thawv feem ntau siab li 42 °.Yog li ntawd, thermal rwb thaiv tsev txheej yog qhov tseem ceeb heev.Tom qab lub tsev ntim khoom ruaj khov, nws yog ib qho tsim nyog yuav tsum tau ntxiv cov txheej txheem thermal rwb thaiv tsev thiab txhim kho cov cua txias.

Lub thermal rwb thaiv tsev txheej ntawm no yog txau nrog polyurethane nyuaj ua npuas ncauj.Tau kawg, muaj lwm yam thermal rwb thaiv tsev ntsuas, xws li thermal rwb thaiv tsev ntaub plaub, pob zeb wool board, silicate board, thiab lwm yam. Qhov kev xaiv tsuas yog nyob ntawm koj qhov kev siv tiag tiag.

Yog li dab tsi yog polyurethane txau?

Polyurethane txauyog hais txog kev siv lub tshuab tshwj xeeb polyurethane txau cov ntaub ntawv raw polyurethane nyob rau hauv qhov kev txiav txim ntawm ntau yam additives xws li foaming agents, catalysts, thiab nplaim retardants, los ntawm high-ceev cuam tshuam thiab tsausmuag kev sib hloov nyob rau hauv ib tug sib tov chamber nrog ib tug me me qhov chaw, thiab ces dhau. los ntawm lub nozzle ntawm rab phom.Lub siab molecular polymer uas tsim cov pos nphuab zoo thiab txau sib npaug ntawm qhov khoom.

Dab tsi yog qhov zoo ntawm kev txau polyurethane ntawm cov thawv ntim khoom?

1. Cov rwb thaiv tsev thermal, kev ua haujlwm siab thiab txuag hluav taws xob.

Lub thermal conductivity ntawm polyurethane thermal rwb thaiv tsev cov ntaub ntawv yog tsawg, thiab lub tshav kub preservation thiab thermal rwb thaiv tsev los yog zoo, uas yog unmatched los ntawm lwm yam thermal rwb thaiv tsev ntaub ntawv.Nyob rau hauv cov vaj tse nyob, polyurethane rigid ua npuas ncauj yog siv los ua waterproof thiab cua sov-insulating ru tsev, nws thickness tsuas yog ib feem peb ntawm cov khoom siv tsoos, thiab nws cov thermal kuj yog ze li ntawm peb npaug ntawm lawv.Vim tias cov thermal conductivity ntawm polyurethane tsuas yog 0.022 ~ 0.033W / (m * K), uas yog sib npaug rau ib nrab ntawm cov extruded board, thiab nws yog qhov qis tshaj thermal rwb thaiv tsev coefficient ntawm tag nrho cov thermal rwb thaiv tsev cov ntaub ntawv tam sim no.

2. Lub ru tsev load yog lub teeb.

Lub polyurethane rwb thaiv tsev cov khoom muaj tsawg ntom ntom thiab lub teeb hnyav, yog li thauj ntawm lub ru tsev thiab phab ntsa yog lub teeb.Lub ru tsev ntawm txau polyurethane thermal rwb thaiv tsev cov ntaub ntawv yog ib feem peb ntawm cov tsoos vov tsev txoj kev, uas yog ib qho tseem ceeb heev los txhim kho lub zuag qhia tag nrho cov qauv ntawm lub tsev thiab txo tus nqi ntawm kev tsim kho, yog li nws yog tsim nyog rau loj-span thiab nyias-plhaub ru tsev vaj tse. .

3. Kev tsim kho tau yooj yim thiab kev ua tiav sai.

Cov thev naus laus zis ntawm no yog polyurethane txau thiab ua npuas dej ntawm qhov chaw, uas tuaj yeem ua haujlwm ntawm kev tsim kho lub ru tsev, uas yog kaum npaug ntau dua li cov khoom siv ib txwm siv.Nws kuj tseem txo qis kev siv zog ua haujlwm, txhim kho qhov chaw ua haujlwm, thiab txo cov pa phem ib puag ncig.

Nyob rau ntawm qhov chaw foaming expansion ntim ntawm polyurethane rwb thaiv tsev cov ntaub ntawv yog 15-18 lub sij hawm, yog li cov tsheb thauj mus los ntawm raw cov ntaub ntawv yog me me.Raws li kev txheeb cais, nws tuaj yeem txo tus nqi tsheb thauj mus los los ntawm ntau dua 80% piv nrog kev siv cov khoom siv ib txwm muaj, thiab nws kuj tseem txo qis kev ua haujlwm ntawm kev thauj mus los ntsug ntawm qhov chaw tsim kho.

4. Zoo engineering zoo, lub neej ua haujlwm ntev thiab tus nqi qis

Polyurethane rwb thaiv tsev cov ntaub ntawv yog ib tug ntom microporous ua npuas ncauj nrog ib tug kaw ntawm tes tus nqi ntawm ntau tshaj 92%.Nws muaj ib tug du self-skinning thiab yog ib tug zoo heev impermeable khoom.Lub tshuab txhaj tshuaj molding ncaj qha yog siv rau hauv kev tsim kho kom tag nrho cov tsim tsis muaj seams Lub impermeability ua tiav hauv paus tshem tawm qhov ua tau ntawm lub ru tsev dej nkag los ntawm seams.

Cov khoom siv polyurethane thermal rwb thaiv tsev tuaj yeem ruaj khov rau hauv lub hauv paus txheej, thiab nws lub zog sib txuas tuaj yeem tshaj qhov tsim kua muag lub zog ntawm cov npuas nws tus kheej, yog li cov khoom siv hluav taws xob polyurethane thermal rwb thaiv tsev thiab txheej txheej yog sib xyaw ua ke, thiab delamination tsis yooj yim tshwm sim, thiab dej nkag mus raws li interlayer yog zam.Cov khoom siv thermal rwb thaiv tsev yog ib qho yooj yim nqus dej thiab noo noo, thiab kev pab cuam lub neej ntawm cov pa dej tsis zoo yog luv luv, thiab lawv yuav tsum tau kho thiab hloov tsis tu ncua;Thaum lub neej kev pab cuam ntawm polyurethane thermal rwb thaiv tsev cov ntaub ntawv tuaj yeem ncav cuag ntau tshaj 10 xyoo, thiab cov nqi kho mob tau txais kev cawmdim nyob rau lub sijhawm no yog qhov tseem ceeb heev.
