Ntxiv rau:Lub tuam txhab tuaj yeem tshawb fawb thiab tsim cov khoom tshiab raws li kev thov tshwj xeeb ntawm peb cov neeg siv khoomCov.
Nta:RFE Polyisocyanate yog cov kab hla kev zoo rau cov nplaum raws cov roj hmab polyurethane, cov roj hmab siv hluavtaws thiab hluav taws xob. RFE Polyisocyanate tseem muaj txiaj ntsig rau kev txhim kho cov khoom siv roj hmab-based. Nws tuaj yeem raug siv ua tus ntoo khaub lig es tsis txhob siv Bayer's deemodur rfe.
Kev siv: Ob lub nplaum nplaum yuav tsum siv nrog lub sijhawm siv tom qab muab tso rau RFE. Qhov ntev ntawm lub sijhawm muaj feem cuam tshuam tsis yog tsuas yog cuam tshuam nrog cov ntsiab lus polymer ntawm cov nplaum, tab sis kuj tseem muaj feem xyuam, antioxygen, cov tshuaj tua kab yees, thiab lwm yam). Thaum nyob ze rau lub sijhawm siv tau, feem ntau yog ob peb teev lossis ib hnub ua haujlwm, nplaum yuav nyuaj rau
Ua haujlwm, thiab viscosity nce sai sai. Thaum kawg, nws dhau los ua Irreversible Jelly. 100 Cov nplaum zoo, hydroxyl polyurethane (Polyurethane account rau ib ncig 20%), RFE ua 4-7. Chloroprene roj hmab (roj hmab nyiaj rau ib ncig 20%), RFE ua 4-7.
Cia: Thov muab tso rau hauv lub pas dej thawj hauv qab 23℃, cov khoom tuaj yeem khaws cia ruaj ruaj rau rau lub hlis. Tag nrho cov bosslinker series cov khoom siv rhiab heev rau cov dej noo; Nws yuav tsim cov pa roj carbon dioxide thiab insoluble urea hauv cov tshuaj tiv thaiv nrog dej. Yog hais tias raug rau saum huab cua lossis lub teeb, nws yuav ceev cov xim hloov xim ceev, tab sis cov kev ua haujlwm yuav tsis cuam tshuam.
