Cov Qauv Kev Loj Hlob ntawm Cov HFOs Uas Zoo Rau Ib Puag Ncig thiab Cov Kev daws teeb meem Catalyst Advanced

Raws li lub hom phiaj ntawm kev hloov pauv huab cua thoob ntiaj teb tau raug ua tiav sai sai, kev lag luam polyurethane tab tom hloov pauv ntau heev. Kev hloov pauv ntawm cov neeg sawv cev tshuab ib txwm mus rau qhov zoo rau ib puag ncig Cov HFOs uas zoo rau ib puag ncig(Hydrofluoroolefins)tau dhau los ua qhov kev txhim kho thev naus laus zis tseem ceeb rau cov ntaub ntawv rwb thaiv tsev, tshuaj tsuag polyurethane ua npuas ncauj (SPF), ua npuas ncauj ruaj khov, rwb thaiv tsev khoom siv hauv tsev, thiab kev siv tsheb. Tib lub sijhawm, kev loj hlob txuas ntxiv ntawm kev thov raucov catalysts HFO ua tau zoo heev tab tom yaum cov chaw tsim khoom kom siv cov tshuaj catalyst uas huv dua, ua haujlwm tau zoo dua, thiab ruaj khov dua.

1. Vim li cas HFOs thiaj li dhau los ua Tus Qauv Thoob Ntiaj Teb

1.1 Los ntawm CFC mus rau HFO: Lub Cim Thib Plaub ntawm Cov Neeg Ua Pa Hluav Taws Xob

Kev hloov pauv ntawm cov neeg sawv cev ua raws li kev cai lij choj thiab kev coj ua ib puag ncig meej:

2. Cov Txiaj Ntsig Tseem Ceeb ntawm HFOs uas Zoo Rau Ib Puag Ncig

✔ GWP qis heev (<1) - txo tau 99.9% piv rau HFCs

Cov HFO xws liHFO-1234yf, HFO-1233zd, thiabHFO-1234zelwj sai sai hauv huab cua nrog lub neej tsuas yoghnub mus rau lub lis piam, txo qis kev cuam tshuam ntawm huab cua.

✔ Xoom ODP - Tsis muaj kev puas tsuaj rau txheej ozone

✔ Kev rwb thaiv tsev zoo thiab siv hluav taws xob tau zoo

HFO ua npuas ncauj ua rau muaj kev ua tau zoo dua thermal conductivity thiab kev ruaj khov dua, ua rau nws zoo tagnrho rau:

• Cov khoom siv tub yees
• Cov vaj huam sib luag rwb thaiv tsev thiab cov vaj huam sib luag sandwich
• Tshuaj tsuag polyurethane ua npuas ncauj (SPF)

✔ Cov kua dej ntau dua & cov qauv cell zoo dua

Cov yam ntxwv ntawm HFO xav taucov catalysts nrog optimized reactivity, tshwj xeeb tshaj yog rau kev sib npaug ntawm kev nce ntawm cov ua npuas dej, kev ntws, thiab kev kho.

3. Yuav Ua Li Cas HFOs Hloov Pauv Kev Lag Luam Polyurethane

3.1 Kev Siv Sai Sai Hauv Cov Chaw Tseem Ceeb

Qhov kev hloov pauv sai no ua rau muaj kev xav tau ceev ceev rauCov tshuaj catalysts polyurethane uas ua kom zoo dua los ntawm HFO.

4. Cov Teeb Meem Catalyst hauv HFO Systems

Qhov kev hloov mus rau HFO blowing agents hloov pauv cov tshuaj dynamics ntawm PU reactions:

Cov qauv HFO feem ntau muaj:

• Qhov pib ua haujlwm qis dua
• Qhov sib txawv ntawm kev yaj ntau dua
• Tus cwj pwm ua npuas ncauj tshiab
• Cov kev cai nruj dua rau kev kho qhov chaw
• Cov viscosity siab dua hauv cov khoom sib xyaw ua ntej

Yog li ntawd, cov neeg ua npuas ncauj yuav tsum siv cov khoom siv ua npuas ncaujcov tshuaj catalysts tshwj xeeb HFOuas muab:

✔ Muaj zog dua rau pem hauv ntej

Txhawm rau them rau qhov txo qis ntawm HFO kev pib ua haujlwm.

✔ Zoo dua qub

Qhov tseem ceeb tshaj plaws rau PIR panels, SPF, thiab cov kab ntau lawm tas mus li.

✔ Kho qhov chaw sai sai

Txhawm rau tiv thaiv kev ntsws thiab cell tawg.

✔ Tsis muaj ntxhiab tsw phem thiab tsis muaj pa phem

Ua raws li cov cai ib puag ncig thoob ntiaj teb.

5. Cov Kev daws teeb meem Catalyst siab heev rau HFO Systems

Ua ib lub chaw tsim khoom siv polyurethane catalyst, peb muab cov khoom tiav tiav uas tsim tshwj xeeb rauCov HFOs uas zoo rau ib puag ncig.

Cov Catalysts Uas Zoo Rau HFO Uas Pom Zoo

• MXC-B20： Kev ncua sijhawm pem hauv ntej zoo heev, kev kho mob tom qab zoo, zoo tagnrho rau HFO SPF
• MXC-R40: Txhim kho qhov kho ntawm qhov chaw, zoo tagnrho rau cov tshuab sib xyaw ua ke nrog dej/HFO

Cov catalysts no daws cov teeb meem kev tsim cov HFO, xws li:

• Kev pib qeeb qeeb
• Qhov profile tsis sib npaug
• Kev tsis ruaj khov ntawm tes
• Kev tawg ntawm cov khoom tom qab kho

6. Kev Pom Kev Lag Luam: HFO + Catalyst Kev Sib Koom Tes Yuav Tswj Hwm Xyoo Caum Tom Ntej

6.1 Kev thov HFO thoob ntiaj teb tab tom loj hlob ntawm >10% txhua xyoo

Tsav los ntawm kev tsim kho kom txuag hluav taws xob, kev siv hluav taws xob hauv tsheb, thiab kev nthuav dav ntawm cov saw hlau txias.

6.2 Cov txheej txheem Catalyst yuav tsum hloov zuj zus tib lub sijhawm

HFOs tsis tuaj yeem ua tiav qhov kev ua tau zoo tshaj plaws yam tsis muaj cov catalysts tsim tshwj xeeb rau lawv cov tshuaj lom neeg.

6.3 Cov tshuaj catalysts uas tsis muaj ntxhiab tsw thiab VOC tsawg yuav yog cov khoom siv tseem ceeb

Cov cai ib puag ncig (EPA, EU F-Gas, Tuam Tshoj lub hom phiaj dual-carbon) tab tom ua kom qhov sib txawv no nrawm dua.

6.4 Cov vaj huam sib luag rwb thaiv tsev PIR raws li HFO yuav nthuav dav sai sai

Tshwj xeeb tshaj yog nyob rau hauv:

• Cov tsev ua ntej
• Kev cia khoom txias
• Kev tsim kho modular
• Kev lag luam ru tsev

7. Xaus Lus: HFO thiab Catalyst Innovation Yuav Txhais Yav Tom Ntej ntawm Polyurethane

Kev hloov pauv thoob ntiaj teb mus rau qhov tshiabCov HFOs uas zoo rau ib puag ncigsawv cev rau lub cib fim keeb kwm rau kev lag luam polyurethane. Raws li HFCs raug tshem tawm thiab cov cai tswjfwm nruj dua, cov chaw tsim khoom yuav tsum tau txais kev ua haujlwm siabCov tshuaj catalysts HFOkom ua tiav qhov kev sib npaug ntawm cov tshuaj tiv thaiv, kev ua haujlwm zoo, thiab kev ruaj khov.

Peb cov kev daws teeb meem catalyst—xws liMXC-B20,MXC-TMA, MXC-10, thiab lwm tus—tau tsim los pab cov chaw tsim khoom polyurethane hloov pauv mus rau lub sijhawm HFO tau yooj yim, xa cov hauv qab no:

• Kev ua haujlwm rwb thaiv tsev zoo dua
• Kev tsim khoom huv dua thiab ntsuab dua
• Kev ua haujlwm ruaj khov hauv ob qho tib si ua npuas ncauj thiab tshuaj tsuag
• Ua raws li cov qauv ib puag ncig thoob ntiaj teb

Los ntawm kev sib txuas ua keCov neeg sawv cev HFOnrog kev ua kom zoo duacov tshuaj polyurethane catalysts, kev lag luam yuav ua tiav ob qho tib si kev ua tau zoo tshaj plaws thiab kev txo cov pa roj carbon uas muaj txiaj ntsig - txhawb nqa lub neej yav tom ntej uas ruaj khov dua thiab siv hluav taws xob tau zoo dua.
