Alkyl Polyether: Ib qho khoom siv tshuaj lom neeg siv ntau yam rau ntau yam kev siv-1
Cov Ntawv Thov Tseem Ceeb
Hauv kev lag luam tshuaj lom neeg, alkyl polyethers yog siv ua cov khoom siv raw rau polyurethane ua npuas ncauj, cov nplaum, cov sealants, thiab elastomers. Polyurethane ua npuas ncauj yog siv dav hauv rooj tog, txaj pw, lub rooj zaum hauv tsheb, thiab cov ntaub ntawv rwb thaiv tsev. Polyurethane nplaum thiab sealants yog siv rau hauv kev sib dhos ntawm cov tsev, tsheb, thiab cov khoom siv hluav taws xob.
Hauv kev lag luam tshuaj, alkyl polyethers ua haujlwm ua cov khoom siv thiab cov emulsifiers hauv cov tshuaj, ua kom lawv ruaj khov thiab yaj tau zoo. Lawv kuj siv los tsim cov defoamers, surfactants, thiab cov neeg sawv cev ntub dej, siv dav hauv qhov ncauj, tshuaj tsuag qhov ntswg, tshuaj qhov muag, tshuaj pob ntseg, thiab tshuaj zawv plaub hau.
Hauv kev lag luam textile thiab ntawv, alkyl polyethers yog siv los ua cov khoom ua kom mos, cov neeg sawv cev tiv thaiv hluav taws xob, thiab cov neeg sawv cev ntub dej. Lawv txhim kho cov khoom mos thiab tiv thaiv hluav taws xob ntawm cov ntaub thiab txhim kho cov ntawv zoo thiab kev ua haujlwm ntau lawm hauv kev ua ntawv.
Hauv cov khoom siv ntxuav khaub ncaws thiab cov khoom siv tu tus kheej, alkyl polyethers yog siv ua surfactants thiab emulsifiers. Lawv qhia tau tias muaj peev xwm ntxuav tau zoo, ua npuas dej, ua npuas dej ruaj khov, ntub dej, thiab ua kom emulsifying, siv dav hauv cov tshuaj zawv plaub hau, tshuaj ntxuav lub cev, tshuaj ntxuav tes, thiab tshuaj ntxhua khaub ncaws.
Tsis tas li ntawd xwb, alkyl polyethers yog siv los ua cov demulsifiers thiab cov roj nplua nyeem hauv kev lag luam roj av, nrog rau cov dej txias thiab cov roj nplua nyeem hauv kev ua hlau.
Cov txheej txheem tsim cov alkyl polyethers feem ntau suav nrog kev kho ua ntej ntawm cov initiators thiab catalysts, cov tshuaj tiv thaiv polymerization qhib lub nplhaib, thiab cov kauj ruam tom qab ua tiav xws li neutralization, adsorption, dehydration, filtration, thiab distillation.
