Polyether polyols rau nplaumlub npe hu ua polyurethane adhesives, polyurethane kua nplaum, yog dav siv nyob rau hauv cov nplaum teb vim lawv cov nplaum zoo heev thiab lwm yam zoo.
Polyether polyols tuaj yeem siv los ua ib feem ntawm cov nplaum, uas tuaj yeem khi cov khoom sib txawv, xws li hlau, yas, thiab ntoo. polyurethane nplaum tuaj yeem muab cov nplaum nplaum zoo.
Tsis tas li ntawd cov polyester polyol rau cov nplaum muaj qhov ua tau zoo, uas tuaj yeem tuav lub zog nplaum thiab ruaj khov, thiab txuas ntxiv lawv lub neej kev pab cuam.
Polyether polyols kuj muaj cov tshuaj tiv thaiv zoo, uas tuaj yeem tiv thaiv corrosion ntawm acids, alkalis, thiab cov kuab tshuaj, thiab tswj kev ruaj ntseg ntawm cov nplaum.
Cov ntsiab lus thiab qhov sib piv ntawm polyether polyols hauv cov nplaum tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm cov khoom sib txawv thiab kev siv

Cia
Cov polyether polyols rau cov nplaum yog ntim thiab thauj hauv cov nruas hlau, IBC nruas, lossis tso tsheb hlau luam.
Muaj cov ntawv qhia meej thiab ruaj ntseg ntawm lub ntim, suav nrog cov khoom npe, qauv, batch tooj, net hnyav, hnub tsim khoom, txee lub neej, chaw tsim khoom lub npe thiab lwm yam.
Cov nplaum polyurethane yuav tsum tau muab ntim rau hauv qhov chaw cia, thiab nws raug nquahu kom sau cov ntim nrog cov roj nitrogen.
Thaum khaws cia thiab kev thauj mus los, nws yuav tsum tau khaws cia kom deb ntawm qhov chaw noo noo, tshav ntuj raug, qhov kub thiab txias, nplaim taws, sparks, thiab lwm qhov chaw ntawm combustion.
Ua tib zoo saib xyuas kom tsis txhob muaj kev sib tsoo nrog cov khoom ntse.
Lub txee lub neej ntawm cov khoom, nyob rau hauv cov ntaub ntawv khaws cia, yog 6 lub hlis txij li hnub tsim khoom.
Cov nplaum polyester polyol yog tsim los siv ntau hom glycol thiab diacid, xws li cov saw ntev aliphatic diacid, ua cov kua qaub.
Lawv ua ke zoo nrog polyisocyanate kom muaj zog adhesion thiab ua haujlwm kub zoo heev.
Lawv muaj kev ua tau zoo rau PET.
Rau daim ntawv thov, BEIQIAO muaj polyester polyol nyob rau hauv ntau yam ntawm molecular luj.
