Kev hloov pauv thev naus laus zis ntawm HFO foaming agent thiab kev tiv thaiv ib puag ncig
Vim muaj kev cai lij choj thoob ntiaj teb uas nruj zuj zus, hydrofluoroolenfins (HFOs), ua tiam neeg thib plaub ntawm cov neeg ua npuas dej, tab tom hloov cov neeg ua npuas dej HCFC thiab HFC ib txwm muaj. Nrog nws qhov muaj peev xwm ua kom sov thoob ntiaj teb tsawg heev (GWP <1) thiab xoom cov yam ntxwv ua rau ozone puas tsuaj (ODP = 0), lub kaw lus ua npuas dej HFO tau dhau los ua txoj hauv kev tseem ceeb rau kev lag luam polyurethane kom ua tiav kev txhim kho ruaj khov. Raws li kev tshawb fawb kev lag luam tshiab, los ntawm xyoo 2026, feem ntawm kev lag luam ntawm HFO hauv cov neeg ua npuas dej polyurethane yuav loj hlob mus txog 58%, nrog rau kev loj hlob txhua xyoo ntawm 12.3%.
Cov txiaj ntsig tseem ceeb ntawm HFO foaming system
1. Kev ua tau zoo tshaj plaws hauv kev ua haujlwm ib puag ncig
- Tus nqi GWP <10: ntau dua 99% qis dua HFC-245fa (GWP = 1030)
- Xoom ODP: tsis ua puas rau txheej ozone thiab ua tau raws li qhov yuav tsum tau ua ntawm Montreal Protocol
- Cov pa phem VOC tsawg: ua tau raws li cov qauv ntawv pov thawj tsev ntsuab xws li LEED thiab BREEAM
2. Kev ua tau zoo heev ntawm kev rwb thaiv tsev
Qhov ua kom sov ntawm cov pa roj ntawm HFO foaming agent (0.013-0.015 W/m·K) zoo dua li cov ntawm cov foaming agent ib txwm muaj, uas tuaj yeem txo qhov ua kom sov tag nrho ntawm polyurethane ua npuas dej los ntawm 15-20%, coj cov txiaj ntsig zoo rau kev txuag hluav taws xob rau cov tub yees, kev rwb thaiv tsev thiab lwm yam teb.
3. Cov teeb meem thiab kev daws teeb meem ntawm kev hloov pauv ntawm cov txheej txheem
Vim nws cov khoom tshwj xeeb ntawm lub cev (xws li lub ntsiab lus kub, cua sov ntawm vaporization, thiab lwm yam), HFO blowing agents tau muab cov kev cai tshiab rau polyurethane formulations thiab cov txheej txheem:
- Yuav tsum tau tswj hwm qhov kev ua haujlwm ntawm cov tshuaj tiv thaiv kom meej dua
- Txhim kho qhov sib npaug ntawm kev ua npuas dej thiab gelling
- Txhim kho qhov sib xws ntawm cov qauv ntawm tes
- Txhim kho kev ua haujlwm ntawm cov substrate bonding
Qhov no yog tus nqi ntawm peb cov catalyst MXC-70 uas tsim tshwj xeeb rau HFO systems.
MXC-70 catalyst: tus khub zoo meej rau HFO system
Cov yam ntxwv tseem ceeb ntawm cov khoom
MXC-70 yog ib qho tshuaj amine uas tsis muaj ntxhiab tsw qab tshwj xeeb uas tsim los daws tau peb qhov teeb meem tseem ceeb ntawm HFO foaming system:
1. Kev tswj cov kab lus teb du
- Tswj qhov sib phim ntawm HFO vaporization thiab polymer curing rate kom raug
- Tsis txhob ua npuas ncauj tawg los yog tawg
- Kev hloov pauv tus qauv ntawm qhov nkhaus nce <5% (ASTM D7487 xeem)
2. Kev ua tau zoo heev ntawm qhov chaw kho
- Txo qhov nplaum ntawm qhov chaw thiab txhim kho qhov tsos ua npuas ncauj
- Ua kom lub sijhawm demoulding luv dua 15-25%
- Haum rau kev txau ntsug thiab saum npoo av
3. Kev nplaum zoo dua ntawm cov khoom siv
- Ua kom muaj zog sib txuas nrog ntau yam khoom siv xws li hlau, yas, ntoo, thiab lwm yam los ntawm 30-50%
- Tshwj xeeb tshaj yog tsim rau cov kab ntau lawm ntawm cov sandwich panels
Cov xwm txheej ntawm daim ntawv thov ib txwm muaj
1. Kev rwb thaiv hluav taws xob
- Txheej rwb thaiv tsev rau lub tub yees/lub tub yees khov
- Kev rwb thaiv tsev dej kub
- Cov khoom siv tub yees lag luam
2. Kev siv hluav taws xob txuag hluav taws xob hauv tsev
- Cov kab ntau lawm ntawm cov hlau sandwich vaj huam sib luag tas mus li
- Kev tsim cov tshuaj tsuag ua npuas ncauj hauv qhov chaw
- Cov ntaub ntawv rwb thaiv tsev yeeb nkab
3. Kev Thauj Mus Los
- Lub cev tsheb thauj khoom txias
- Cov ntaub ntawv rwb thaiv tsev dej hiav txwv
- Cov ntaub ntawv sib xyaw ua ke ntawm kev tsav dav hlau
