Kev Taw Qhia
Nyob rau hauv xyoo tas los no,cov tshuaj polyurethane catalysts uas tsis muaj ntxhiab tsw qab tau dhau los ua ib qho kev loj hlob hauv kev lag luam polyurethane. Nrog rau cov qauv ib puag ncig thoob ntiaj teb uas nruj zuj zus thiab cov neeg siv khoom xav tau ntau ntxiv rau cov chaw nyob hauv tsev huv dua, qhov kev loj hlob ntawmcov tshuaj polyurethane catalysts uas tsis muaj pa phem, tsis muaj ntxhiab tsw phem tab tom ua kom nrawm dua. Cov chaw tsim khoom ntawm cov ua npuas dej uas yoog tau thiab tawv, cov tshuaj pleev xim, cov nplaum, thiab cov sealants tam sim no tab tom muab qhov tseem ceeb rau cov catalysts uas sib xyaw ua ke kev ua haujlwm siab, VOC qiss, thiabkev phooj ywg ib puag ncig tsis muaj kev cuam tshuam rau reactivity.
Vim Li Cas Cov Tsw Qab Tseem Ceeb Hauv Kev Tsim Khoom Polyurethane
Cov tshuaj amine catalysts ib txwm muaj, thaum ua haujlwm tau zoo heev ntawm kev txhawb nqa cov tshuaj polyurethane ntawm isocyanates thiab polyols, feem ntau tso tawm cov amines volatile thaum lub sijhawm tsim khoom lossis tom qab kho. Cov pa phem no tuaj yeem ua rau:
Smuaj zog amine tsws hauv cov khoom tiav lawm (xws li ua npuas dej thiab cov tshuaj pleev xim)
Sab hauv tsevteeb meem huab cua zoo
Ua Haujlwmr kev raug mob thiab kev ua raws li txoj cai
Yuav kom tau raws li qhov xav tau kev noj qab haus huv thiab ib puag ncig tam sim no, cov lag luam tab tom hloov pauv sai sai mus raucov tshuab catalyst uas tsis muaj ntxhiab tsw, tsis muaj volatilityCov catalysts no txo cov pa phem thaum tswj hwm qhov ua npuas dej thiab kev ua kom zoo tshaj plaws.
Kev Sawv Ntxov ntawm Cov Tshuaj Amine Uas Muaj Tsw Qab Tsawg
Cov tshuaj polyurethane catalysts uas tsis muaj ntxhiab tsw qab yog tsim los rautxo qhov volatility thiab txhim kho kev xaivLos ntawm kev hloov pauv lawv cov qauv molecular lossis qhia cov pab pawg ua haujlwm reactive, cov catalysts no tuaj yeem sib txuas nrog cov polyurethane matrix, yog li tiv thaiv kev ua kom cov tshuaj tsw qab tsis muaj zog.
Cov thev naus laus zis tseem ceeb hauv daim teb no suav nrog:
Cov tshuaj catalysts amine uas muaj zoguas covalently bonds rau hauv lub polymer
Cov tshuaj catalysts amine uas raug thaivnrog kev tswj hwm kev tso tawm thaum lub sijhawm tshuaj tiv thaiv
Cov kab ke tertiary amine uas tsis muaj pa phem tsawgnrog kev ruaj khov hydrolytic zoo dua
Piv txwv li, cov tshuaj catalysts xws li Mingxu New Materials'MXC-R40 thiabMXC-37 yog tsim tshwj xeeb los ua kom pom tseebtsw qab tsawg, ua haujlwm siab, thiab cov khoom ua npuas dej sib npaugLawv siv dav hauvcov tshuaj tsuag khov kho, cov khoom siv rwb thaiv tsev, cov khoom ua npuas ncauj sab hauv tsheb, thiab Cov txheej txheem HFO.
Cov Tsav Tsheb Ib puag ncig thiab Kev Cai Lij Choj
Muaj ntau yam tseem ceeb thoob ntiaj teb uas ua rau kev saws txais yuav sai duacov tshuaj polyurethane catalysts uas tsis muaj ntxhiab tsw qab:
Ntau zuj zusCov cai tswjfwm nruj ntawm VOC (cov organic compound uas tsis muaj zog) thiab kev tso pa tawm hauv Tebchaws Europe, North America, thiab Asia.
Cov ntawv pov thawj kev ruaj khov (LEED, BREEAM, GREENGUARD) tab tom tsav tsheb siv cov khoom siv huv dua.
Kev thov ntawm cov neeg siv khoom rau cov rooj tog uas muaj pa phem tsawg, cov txaj pw, thiab cov khoom siv sab hauv tsheb tab tom loj hlob tuaj.
Kev hloov pauv ntawm kev lag luam mus rau HFO thiab cov tshuab ua npuas dej, uas xav tau cov catalysts xaiv ntau dua.
Cov chaw tsim khoom sivcov thev naus laus zis catalyst qis-emission tsis yog tsuas yog ua tau raws li cov cai tswjfwm xwb tab sis kuj txhim kho tus nqi hom thiab tau txais txiaj ntsig sib tw hauv kev lag luam xa khoom tawm.
Cov txiaj ntsig ntawm kev siv cov tshuaj Polyurethane Catalysts uas tsis muaj ntxhiab tsw qab
Kev sivcov tshuaj catalysts uas tsis muaj ntxhiab tsw qabHauv kev tsim cov polyurethane muaj ntau qhov zoo:
Txo cov ntxhiab tsw hauv cov khoom ua npuas ncauj tiav lawm
Kev nyab xeeb ntawm cov neeg ua haujlwm thiab ib puag ncig ntawm lub Hoobkas zoo dua
Zoo dua huab cua sab hauv tsev rau cov neeg siv kawg
Ua raws li cov qauv kev tso pa tawm VOC
Kev ua haujlwm ruaj khov thiab cov qauv ua npuas ncauj nce siab sib xws
Cov txiaj ntsig no ua raucov tshuaj polyurethane catalysts uas tsis muaj ntxhiab tsw qab kev xaiv dav dav rau cov chaw tsim khoom ua npuas ncauj thoob ntiaj teb.
Cov Ntawv Thov Thoob Plaws Polyurethane Systems
