Nyob rau hauv lub ntiaj teb ntawm hloov pauv polyurethane (PU) Ua Npuas Ncauj Ntau Lawm, Kev Ntsuas Cov Qauv Tseem Ceeb, kev muag khoom, thiab tag nrho cov kev ua tau zoo. Rau cov tuam tsev ntawm cov rooj tog zaum, kab txaj, tsheb tuam tsev, thiab ntim khoom ntim, xaiv txoj cai polyol yog qhov tseem ceeb rau kev ua npuas dej zoo thiab tus nqi.
Dab tsi yog polyether polyols?
Polyether Polyols yog rov ua kua cov kua polymers tsim los ntawm cov tshuaj pleev roj polymerization ntawm propylene oxide (po) lossis ethylene oxide (EO) nrog tus pib. Thaum ua ke nrog Isocyanates zoo li TDI 80/20, lawv tsim cov polyurethane latrix. Cov molecular hnyav, kev ua haujlwm, thiab hydroxyl tus nqi ntawm cov polyol muaj txiaj ntsig ntawm cov npuas dej kom yooj yim, ceev, thiab kav ntev.
Cov qib tseem ceeb rau FLEAMSIBLE FOAM: PPG3000 thiab PPG3500
Ntawm beiqiao cov khoom siv tshiab, peb muab ob ntawm cov nrov tshaj polyetic polyol cov qib rau kev tsim khoom siv ua npuas ntau:
PPG3000:
Ib tug General - lub hom phiaj polyether polyether polyol nrog lub zog hydroxyl nrog cov qauv kev tsim khoom, siv ntau yam hauv kev ua npuas ncauj. Nws muaj zoo flowerability thiab reactivity, ua rau nws zoo tagnrho rau kev thaiv ua npuas ncauj, rooj tog zaum rooj tog, thiab dav} lub hom phiaj sponges.
PPG3500:
Qhov no siab dua molecular hnyav polyol muab kev ua kom zoo nkauj thiab hloov tau. Nws yog tsim tshwj xeeb rau cov mos mos {{1} kov cov rooj tog ua npuas dej ua npuas dej, thiab khoom kim heev uas yuav tsum muaj kev nplij siab zoo dua.
Cov polyols kom ua npuas zoo, cov qauv xov tooj ntawm tes, thiab cov ntxhiab tsw qab, ua kom muaj kev xav tau nce ntiaj teb.
Vim li cas polyether polyols teeb meem
Kev xaiv ntawm polyether polyols cuam tshuam rau ob peb qhov tseem ceeb foam cov khoom lag luam:
Ntsej zog & Hardness: Polyols tswj cov npaus kev ruaj khov. Siab dua molecular hnyav polyols zoo li PPG3500 cov txiaj ntsig softer ua npuas.
RESILIAS & COLYOLS COLLE HEEV LI CAS UA npuas ncauj tom qab compression - tus yuam sij rau txumpajes thiab cushions.
Ua npuas ncauj: Flowability thiab reactivity ntawm polyol txiav txim siab cov smoothness ntawm kev tsim khoom thiab pwm {0} sau tus cwj pwm.
Kev Xav Ua Lag Luam thiab Kev Lag Luam Kev Lag Luam
Lub ntiaj teb xav tau rau kev ua kom yoog raws li polyurethane ua npuas ncauj ntxiv kom sawv, tshwj xeeb yog nyob rau hauv Asia- pacific thiab Middle East. Polyether Polyols yog nyob ntawm qhov chaw ntawm txoj kev loj hlob no, tsav los ntawm:
Nce cov neeg siv khoom nyiam rau cov rooj tog zaum xis, ruaj ruaj
Kev loj hlob sai ntawm cov tsev nyob thiab tsev so kev lag luam
Kev siv tshuab nce thiab cov nplai hauv cov kab ua npuas ncauj ntau lawm
Hauv thaj chaw xws li tim lyiv teb chaws thiab cov rooj tog zaum yog nthuav dav sai, kev ntseeg tau ntawm polyols zoo li PPG3000 thiab ua kom muaj zog ruaj khov thiab cov neeg siv khoom muaj kev txaus siab.
Peb txoj kev cog lus rau kev ua tau zoo
Ntawm beiqiao cov khoom siv tshiab, peb ua kom ntseeg tau tias peb polyether polyols yog tsim nyob rau hauv nruj zoo tswj hwm kev tswj hwm, thiab huv zoo nkauj heev, thiab ruaj khov viscosity. Peb txhawb peb cov neeg tau taw qhia cov kev taw qhia txuj ci, tsim qauv kev ua kom zoo dua qub, thiab kev xa khoom sai rau cov lag luam thoob ntiaj teb.
Txawm hais tias koj tsim rooj so, lossis daim duab txaj, lossis cov khoom sib tw, peb cov khoom PPG xa cov khoom, xwm yeem, thiab tus nqi.
