All polyol classes used in polyurethanes have a set of unique attributes that make them useful as the soft-segment in specific polyurethane elastomer applications. Xaiv cov polyol zoo tshaj plaws rau cov mis tshwj xeeb tuaj yeem yog qhov sib txawv ntawm kev ua lub siab- Cov khoom lag luam zoo lossis muaj tsawg} ua yeeb yam. Tus yuam sij rau kev xaiv kom tsim nyog yog qhov kev nkag siab zoo ntawm cov yam ntxwv hauv nruab rau txhua tus kab ke Polyol Chemistry.
Dab tsi yog polyester - polyol cov kev xaiv uas tawm hauv kev xaiv cov ntawv thov polyurethane zoo tshaj?
Cov ntaub ntawv (cov tshuaj pleev xim, cov nplaum, cov duab ntxas, thiab ua npuas ncauj thiab cov ntaub ntawv sib txawv ntawm cov tsev neeg ntawm polyester polyols uas suav nrog:
Aliphatic raws Polyester Polyols
Polyester Polyols
Policaprolactone Polyols
Polycarbonate Polyols
Cov qauv kev xaiv muaj cov kev cai lij choj thiab kev ua tau zoo rau cov cwj pwm uas yuav tsum muaj nyob hauv Polyurethane Elastomer. Polyester raws qhov chaw etethane, piv txwv li, yog siv rau lawv lub zog thiab kev ua tau zoo, kev ua haujlwm ntawm cov khoom siv tsis zoo thiab kev sib raug zoo ib puag ncig.
Dab tsi yog cov tseem ceeb ntawm cov polyurethanes raws li polyester polyols?
Piv rau polyether polyols hauv polyurethane elastomers, polyesters muaj cov khoom siv lub cev ntau dua, txiav thiab looj kev puas tsuaj zoo dua qub thiab zom ua cov qaug zog zoo dua. Lawv yog cov tawv thiab ruaj.
Polyester Polyols hauv polyterethane kuj pom zoo tsis kam rau cov roj, roj, roj thiab tsis yog cov tshuaj lom.
Polyester nraub qaum cov thermo -}} ecidative stability uas ua rau lawv zoo dua rau siab thov.
Polyester raws Urethae elastomers qhia zoo adhesion zoo ib txwm siv substrates.
Dampening Dampening thiab poob siab kev nqus cov khoom
Qhov chaw nyob hauv qhov chaw hauv polyester polyols ua rau lawv xav tau zoo rau kev lag luam hauv qab no thiab kev thov rau Polyurethane Elastomers:
Roj pob thiab cov ntawv thov tsuas: cov ntxaij vab tshaus, conveyor siv scraper tuaj
Cov log, muaj thiab luam ntawv yob
Pipeline npua
Ntawv nplaum
Nkawm khau thiab khau soles
Muaj cov ntawv thov xav tau zoo thermal stability.
Cov Khoom Noj Hu Rau (FDA Ua Raws)
TPUs rau Automotive thiab Cable Tsho
Rigid thiab tshuaj tsuag ua npuas rau cov neeg muaj ntxhiab polyester polyols.
