Cov txiaj ntsig tseem ceeb ntawm cov polyurethane hauv qab
Cov khau polyurethane (PU) tau dhau los ua thawj qhov kev xaiv ntawm kev lag luam khau niaj hnub no vim lawv cov khoom siv tshwj xeeb. Cov khoom siv ua tau zoo no yog ua los ntawm kev tshuaj lom neeg meej ntawm isocyanate prepolymers (xws li diphenylmethane diisocyanate) thiab polyols nyob rau hauv qhov kev ua ntawm cua sov thiab catalysts. Nws cov txiaj ntsig tseem ceeb suav nrog:
- Kev ywj pheej zoo heev: piv rau qhov yooj ywm thiab kev rov qab ua tau zoo ntawm cov tawv nqaij ntuj, muab qhov kev xav zoo thiab xis nyob rau tus neeg hnav
- Kev ua haujlwm zoo heev rau kev nqus dej: tshwj xeeb tshaj yog rau cov khau kev nyab xeeb, khau kis las thiab lwm yam kev siv uas xav tau kev tiv thaiv ntxiv
- Lub neej ntev: cov qauv nto du thiab ntom tiv taus kev hnav thiab tsim kua muag txhua hnub, ua kom lub neej ua haujlwm ntev
- Cov yam ntxwv sib dua: sib dua 20-30% dua li cov roj hmab ib txwm muaj, ua rau kev hnav xis dua
MXS-6 catalystTug: Ib qho khoom siv tseem ceeb hauv kev tsim cov khau PU
Ua ib qho tshuaj silicone surfactant uas siv tau rau kev lag luam, MXS-6 (CAS NO. 83016-70-0, sib npaug rau DC193) ua lub luag haujlwm tseem ceeb hauv kev tsim cov khau PU:
1. Cov yam ntxwv ntawm cov khoom
- Optimized rau cov ntawv thov polyurethane ua npuas ncauj
- Cov khoom siv zoo heev ntawm qhov chaw
- Haum rau txhua hom khau thiab tag nrho cov tawv nqaij daim ntawv thov
- Kev lag luam-paub zoo ruaj khov zoo
2. Cov Haujlwm Tseem Ceeb
- Txhim kho cov qauv ntawm tes: xyuas kom meej tias cov khoom siv sib xws thiab txhim kho cov khoom siv kho tshuab
- Txhim kho cov yam ntxwv ntawm kev ntws: ua kom cov khoom siv raw khoom zoo meej rau kev sau cov pwm uas muaj cov kab sib txawv
- Tswj cov txheej txheem tshuaj tiv thaiv: txhim kho kev ua haujlwm zoo thiab kev sib xws ntawm cov khoom
- Tswj kom tsis muaj ntxhiab tsw phem: ua tau raws li cov kev cai tiv thaiv ib puag ncig uas nruj dua
Cov cheeb tsam thov thiab cov kev daws teeb meem
Peb muab cov kev daws teeb meem polyurethane catalyst rau ntau lub tuam txhab tsim khau:
1. Khau yooj yim: sib npaug qhov xis nyob thiab ruaj khov
2. Khau kev nyab xeeb: txhim kho kev tiv thaiv thiab kev cuam tshuam
3. Khau kis las: ua kom lub zog tawm tswv yim zoo dua thiab nqus tau qhov poob siab
4. Khau looj ua haujlwm: txhim kho kev tiv thaiv kev hnav thiab kev nplij siab rau txhua lub caij nyoog
Vim li cas ho xaiv pebMXS-6 catalyst?
- Kev txheeb xyuas kev lag luam: sib npaug rau DC193, zoo lav
- Kev txhawb nqa kev tshaj lij: muab cov kev pabcuam kev txawj ntse thiab kev taw qhia daim ntawv thov tiav
- Cov kev daws teeb meem tshwj xeeb: ua kom zoo dua cov qauv raws li cov neeg siv khoom xav tau tshwj xeeb
- Kev muab khoom ruaj khov: xyuas kom meej tias muaj kev txuas ntxiv mus ntxiv
Hauv kev ua lag luam khau uas muaj kev sib tw ntau zuj zus, cov tshuaj polyurethane zoo yog qhov tseem ceeb rau kev tsim cov hauv qab PU ua haujlwm tau zoo. MXS-6 pab cov chaw tsim khoom kom zoo dua cov nqi tsim khoom thiab txhim kho kev sib tw ua lag luam thaum ua kom cov khoom zoo.
Peb ua tsaug caw cov tuam txhab tsim khau thoob ntiaj teb los tham txog kev koom tes thiab ua ke tsim cov kev daws teeb meem polyurethane tshiab. Yog xav paub ntxiv txog cov khoom lossis xav tau cov qauv, thov hu rau peb pab neeg tshaj lij.
