Raws li cov lag luam siv zog rau kev coj ua kom ruaj khov thiab zoo rau ib puag ncig, kev hloov pauv ntawm cov neeg sawv cev tshuab ib txwm mus rauCov Hydrofluoroolefins (HFOs)tau dhau los ua neeg nyiam zuj zus. Qhov kev hloov pauv no pom tseeb tshwj xeeb hauv kev tsim cov polyurethane ua npuas ncauj, qhov twgCov txheej txheem HFOtau tshwm sim los ua ib qho kev daws teeb meem txhim khu kev qha rau kev ua kom muaj zog ua npuas dej thaum txo cov kev cuam tshuam rau ib puag ncig.
Hauv tsab xov xwm no, peb yuav tshawb nrhiav qhov zoo ntawm HFO systems, lub luag haujlwm ntawmcov neeg sawv cev rau cua tshuabzoo li HFO hauv kev lag luam polyurethane, thiab yuav ua li casMXC-70, ib qho tshuaj catalyst amine uas muaj ntxhiab tsw qab zoo heev, ua rau kev ua haujlwm ntawm polyurethane foams tsim los ntawm HFO technology zoo dua.
Lub HFO Foaming System yog dab tsi?
Cov Hydrofluoroolefins (HFOs)yog ib chav kawm ntawm cov neeg sawv cev siv los tsim cov polyurethane ua npuas ncauj, paub txog lawv qhov qis dua qhov ua rau lub ntiaj teb sov (GWP) piv rau cov hydrofluorocarbons ib txwm muaj (HFCs). HFOs pab txhawb rau kev tsim cov polyurethane ua npuas ncauj zoo thaum daws qhov kev thov loj hlob rau kev coj ua tsim khoom uas muaj lub luag haujlwm rau ib puag ncig. Qhov no ua rau HFO systems tsim nyog heev rau cov lag luam uas tsom mus rau kev txo lawv cov teeb meem ib puag ncig, xws li kev tsim kho, tub yees, thiab kev rwb thaiv tsev ua npuas ncauj.
LubHFO foaming systemsiv cov tshuaj ua npuas dej uas ua los ntawm HFO los tsim cov ua npuas dej uas muaj cov yam ntxwv zoo heev rau kev rwb thaiv tsev kub, kev siv hluav taws xob zoo, thiab kev ruaj khov mus sij hawm ntev. Cov txheej txheem no zoo tagnrho rau kev tsim cov ua npuas dej polyurethane uas siv rau hauv kev rwb thaiv tsev rau cov khoom siv hluav taws xob, cov vaj huam sib luag tsim kho, kev rwb thaiv tsev ua npuas dej, thiab ntau ntxiv.
Qhov Tseem Ceeb ntawm Cov Neeg Sawv Cev Tshuab Hauv Kev Tsim Khoom Polyurethane Ua Npuas Ncauj
Cov tshuaj ua kom cua tshuab ua lub luag haujlwm tseem ceeb hauv kev tsim cov polyurethane ua npuas ncauj. Lawv yog lub luag haujlwm rau kev nthuav dav cov ua npuas ncauj thiab tsim cov cell network, uas muab cov qauv ua npuas ncauj thiab cov khoom rwb thaiv tsev. Cov tshuaj ua kom cua tshuab ib txwm muaj xws li hydrofluorocarbons tau siv dav, tab sis lawv cov GWP siab tau ua rau muaj kev tsim cov lwm txoj hauv kev xws li hydrofluoroolenfins.
Cov neeg sawv cev ua los ntawm HFOmuab ntau yam txiaj ntsig:
GWP qis dua: HFOs muaj qhov cuam tshuam tsawg dua rau kev kub ntawm lub ntiaj teb piv rau HFCs, ua rau lawv zoo rau ib puag ncig dua.
Kev rwb thaiv cua sov zoo dua: HFOs pab txhawb rau kev tsim cov ua npuas dej uas muaj cov khoom rwb thaiv tsev zoo heev, uas yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev lag luam xws li kev tsim kho thiab kev tub yees.
Kev sib raug zoo nrog cov khoom siv uas twb muaj lawm: Cov kab ke HFO feem ntau tuaj yeem koom ua ke rau hauv cov kab ntau lawm uas twb muaj lawm nrog kev hloov kho me me xwb, ua rau kev hloov pauv yooj yim dua rau cov chaw tsim khoom.
