Polyether polyol(polyether luv luv) yog ib hom roj hluavtaws uas muaj qhov muag loj tshaj plaws tam sim no. Nws yog linear polymer ua los ntawm ethylene oxide, epoxypropane, epoxybutane thiab lwm yam raw khoom los ntawm lub nplhaib-qhib homopolymerization los yog copolymerization nyob rau hauv qhov kev txiav txim ntawm catalyst. Polyether polyol yog cov tsim khoom loj tshaj plaws ntawm polyethers, nrog glycerinum (glycerin) ua tus pib thiab epoxides (feem ntau PO thiab EO yog siv ua ke), txhua yam ntawm polyether polyols yog tsim los ntawm kev hloov txoj kev pub mis (sib xyaw lossis cais ntxiv), ntau npaum li cas piv, kev txiav txim pub mis thiab lwm yam kev mob ntawm PO thiab EO. Cov ntawv thov tseem ceeb yog raws li hauv qab no:
1. Detergent lossis defoaming tus neeg sawv cev
Polyether polyol tuaj yeem siv rau kev npaj cov tshuaj tua hluavtaws uas tsis tshua muaj foaming thiab siab detergency, thiab siv los ua tus neeg saib xyuas defoaming hauv ntawv ua los yog fermentation kev lag luam nrog rau cov defoaming tus neeg saib xyuas kom tsis txhob muaj cua nkag mus rau hauv cov ntshav thaum lub sij hawm cov ntshav ncig ntawm cov khoom siv dag zog. lub plawv-lub ntsws tshuab.
2. Excipient thiab emulgator
Polyether muaj toxicity tsawg thiab feem ntau yog siv los ua tshuaj excipient thiab emulsifier, uas yog feem ntau siv nyob rau hauv lub qhov ncauj thiab qhov ntswg sprays, qhov muag thiab pob ntseg tee thiab tshuaj zawv plaub hau.
3. Tus neeg saib dej ntub dej
Polyether yog tus neeg sawv cev ntub dej zoo thiab tuaj yeem siv rau hauv dyeing ntaub, kev txhim kho duab thiab electroplating acid da dej. F68 yog siv rau hauv cov khoom qab zib kom tau txais cov suab thaj ntau ntxiv vim muaj dej permeability ntxiv.
4. Antistatic tus neeg sawv cev
Polyether yog ib qho muaj txiaj ntsig antistatic tus neeg sawv cev, uas tuaj yeem muab kev tiv thaiv hluav taws xob ruaj khov rau cov hluavtaws fiber ntau.
5. Dispersing tus neeg sawv cev
Polyether yog siv los ua dispersants hauv emulsion txheej. Nws tuaj yeem siv los ua emulsifier hauv polymerization ntawm vinyl acetate emulsion. Tsis tas li ntawd, nws yog ib qho tshuaj tua kab emulsifier hauv kev ua liaj ua teb, lub coolant thiab lubricant hauv hlau txiav thiab sib tsoo thiab lubricant hauv vulcanization.
6. Demulsifier
Polyether tuaj yeem siv los ua demulsifier rau cov roj crude, uas tuaj yeem tiv thaiv kev tsim cov nplais tawv hauv cov kav dej thiab tuaj yeem siv rau kev rov qab los ntawm cov roj thib ob.
7. Papermaking additives
Polyether tuaj yeem siv los ua cov ntaub ntawv ntxiv, uas tuaj yeem txhim kho cov ntawv zoo. Nws kuj tseem siv tau los ua cov tshuaj bleaching.
8. Kev npaj thiab kev thov
Polyether polyol series cov khoom siv feem ntau yog siv rau hauv kev npaj cov yas polyurethane foaming yas, dav siv hauv tub yees, lub freezers, tsheb tub yees, thermal baffles, piping rwb thaiv tsev thiab lwm yam. Cov khoom tsim nrog polyether polyol muaj cov thermal conductivity coefficient thiab ruaj khov, thiab polyether polyol tseem yog ib qho tseem ceeb raw khoom rau kev npaj ntawm premixed polyether polyols.
Kev tsim cov polyether polyol feem ntau yog siv hauv polyurethane foaming plastics hauv kev lag luam polyurethane. Cov hom tseem ceeb muaj xws li polyoxypropylene polyol, polytetrahydrofuran ether polyol.
