Polyether polyolsyog cov khoom siv tseem ceeb hauv kev tsim cov polyurethanes.
Polyether-raws li polyurethanes nthuav tawm txhim kho hydrolytic stability thiab zoo heev tiv taus rau cov acids tsis muaj zog thiab cov hauv paus piv rau polyester-based polyurethanes.
Polyether Polyols yog tsim los ntawm reacting organic oxide thiab glycol.
Lub ntsiab organic oxide siv yog Ethylene Oxide, Propylene Oxide, Butylene Oxide, Epichlorohydrin.
Lub ntsiab glycols siv yog Ethylene Glycol, Propylene Glycol, Dej, Glycerine, Sorbitol, Sucrose, THME.
Polyols muaj cov pab pawg reactive hydroxyl (OH) uas cuam tshuam nrog isocyanate (NCO) pawg ntawm isocyanates los ua polyurethanes.
Muaj ntau ntau hom polyether polyols rau polyurethane. PU cov ntaub ntawv nrog kev ua tau zoo sib txawv tuaj yeem tau txais nrog cov tshuaj tiv thaiv ntawm cov pib sib txawv thiab olefin polymerization.
Los ntawm kev hloov kho PU cov ntaub ntawv raw lossis hloov cov catalyst, polyether kev ua tau zoo tuaj yeem hloov kho. Cov neeg pib no muaj xws li cawv cawv, ternary cawv, tetrahydrofuran, thiab aromatic polyether polyols, thiab lwm yam.

Ntim thiab khaws cia
Polyether polyol txheej, ntim thiab thauj hauv cov nruas hlau, IBC nruas, lossis ISO tso tsheb hlau luam.
Feem ntau, rau Hlau nruas rau packing, nqa hnyav 200kg. Rau tons ntawm ntim ntim, nqa hnyav 1000kg.
Cov cim meej thiab ruaj khov ntawm lub ntim nrog cov khoom npe, qauv, batch NO., NW, hnub tsim khoom, txee lub neej, chaw tsim khoom npe, thiab lwm yam.
Yuav tsum tau muab kaw cia thiab pom zoo kom siv lub thawv nrog nitrogen.
Ua tib zoo saib xyuas kom tsis txhob muaj kev sib tsoo nrog cov khoom ntse thiab xau.
Lub txee lub neej yog 6 lub hlis raws li kev cia khoom
