Cyclopentane tuaj yeem siv tau zoo hauv kev tsim cov polyurethane ua npuas ncauj.
Kev mus kom ze: Ib qho - cov txheej txheem tshuaj tiv thaiv yog ua haujlwm, hloov cyclopentane rau cov tshuaj chlorofluorocarbon (CFC) tshuab tshuab.
Formulation tsis: Qhov loj piv ntawm cyclopentane rau hloov polyether polyol yog teem ntawm 32:100.
Kev ntsuas kev nyab xeeb: txhawm rau hais txog qhov flammability thiab tawg ntawm cyclopentane, nitrogen purging yog siv thaum tsim khoom kom muaj kev nyab xeeb.
Cov khoom kawg: Cov khoom ua npuas ncauj yooj yim tsim los ntawm cov cuab yeej siv no ua tau raws li "thawj-qib" cov qauv zoo thiab tau ua tiav hauv thaj chaw xws li cov ntaub ntawv cushioning.
Txawm li cas los xij, cyclopentane tsis tau dhau los ua qhov kev xaiv tseem ceeb rau kev tsim khoom ntawm polyurethane hloov tau yooj yim, feem ntau yog vim li cas hauv qab no:
Qhov sib txawv ntawm cov yam ntxwv ntawm tus txheej txheem: Kev tsim ua npuas ncauj yooj yim ua ntej "qhib- cell" qauv thiab ua pa. Hauv qhov sib piv, cov tshuab cyclopentane- feem ntau cuam tshuam nrog "kaw- cell" cov qauv ntawm cov foams nruj tsim los rau cov thermal conductivity tsawg- ua haujlwm los ntawm cov txheej txheem foaming uas txawv ntawm cov tshuab feem ntau siv rau cov foams hloov tau (xws li dej-isocyanate cov tshuaj tiv thaiv foaming).
Kev paub ntau yam thiab tus nqi: Cov txheej txheem yuav tsum muaj cov khoom siv tshwj xeeb (xws li kev hloov kho polyethers thiab ua npuas ncauj stabilizers), txwv nws txoj kev siv dav.
Cim npe nrov: cyclopentane yog siv nyob rau hauv saj zawg zog polyurethane ua npuas ncauj, Tuam Tshoj cyclopentane yog siv nyob rau hauv saj zawg zog polyurethane ua npuas ncauj manufacturers, lwm tus neeg, Hoobkas
