FAQ
Q: Dab tsi yog qhov zoo ntawm polyester polyols piv rau lwm hom polyols (xws li polyether polyols) hauv CASE daim ntawv thov?
A: Polyester polyols feem ntau muab cov hardness zoo dua, tshuaj tiv thaiv, thiab hydrolysis tsis kam, ua rau cov khoom kawg ua tau zoo dua hauv kev siv sab nraum zoov lossis ib puag ncig uas nws raug dej. Lawv kuj zoo li muab cov khoom lag luam zoo dua cov xim ruaj khov thiab ua rau yellowing, tshwj xeeb tshaj yog rau cov ntawv thov uas yuav tsum muaj xim ruaj khov.
Q: Puas yog CASE cov khoom tsim nrog polyester polyols ib puag ncig tus phooj ywg?
A: Polyester polyols tuaj yeem tsim los ntawm cov khoom siv txuas ntxiv dua tshiab xws li cov roj zaub, thiab cov khoom siv bio-based polyester polyols tsis tsuas yog txo qhov kev cia siab ntawm fossil fuels, tab sis kuj txo cov pa roj carbon hneev taw ntawm cov khoom, nyob rau hauv txoj kab nrog kev lag luam tam sim no kom muaj kev ruaj ntseg. cov ntaub ntawv. Txawm li cas los xij, tsis yog txhua tus polyester polyols yog bio-based, nyob ntawm cov khoom piav qhia.
Q: Yuav ua li cas xaiv cov polyester polyol kom tau raws li cov kev xav tau ntawm daim ntawv thov tshwj xeeb CASE?
A: Xaiv txoj cai polyester polyol yuav siv sij hawm rau hauv tus account ntau yam, nrog rau cov khoom kawg ntawm cov khoom uas xav tau (xws li hardness, yooj, tshuaj tsis haum), daim ntawv thov ib puag ncig (xws li kub ntau, av noo), cov nqi siv nyiaj , thiab seb puas yuav tsum tau ntawv pov thawj tshwj xeeb (xws li qib kev nyab xeeb zaub mov, VOC qis). Feem ntau, cov neeg muag khoom muab cov ntaub ntawv qhia txog kev siv tshuab thiab cov txheej txheem kev thov, thiab pom zoo ua haujlwm ze nrog pab pawg neeg muab kev pabcuam los ua qhov kev ntsuam xyuas me me kom pom qhov zoo tshaj plaws.
