    Khoom Properties & Features

    RFE polyisocyanate yog ib qho zoo heev crosslinker rau cov nplaum raws li polyurethane, roj hmab ntuj thiab Synthesis roj hmab. RFE polyisocyanate kuj tseem siv tau los txhim kho cov nplaum ntawm cov khoom siv roj hmab. Nws tuaj yeem siv los ua crosslinker tsis yog Bayer's Desmodur RFE.
    RE 1

    Kev siv

    Ob lub ntsiab lus nplaum yuav tsum tau siv nrog lub sijhawm siv tom qab muab tso rau hauv RFE.
    Lub sijhawm siv sijhawm ntev tsis yog tsuas yog cuam tshuam nrog cov ntsiab lus polymer ntawm cov nplaum, tab sis kuj tseem muaj lwm yam cuam tshuam (xws li resin, Antioxygen, plasticizer, hnyav, thiab lwm yam.
    Thaum nyob ze rau lub sijhawm siv, feem ntau yog ob peb teev lossis ib hnub ua haujlwm, cov nplaum ua haujlwm nyuaj dua, thiab viscosity nce sai sai.
    Thaum kawg, nws dhau los ua jelly irreversible. 100 zoo nplaum, Hydroxyl polyurethane (Polyurethane account rau ib ncig ntawm 20%), RFE ua 4-7. chloroprene roj hmab (Rubber account rau ib ncig ntawm 20%), RFE ua 4-7.

    Ntim

    Pob: 0.75kg / lub raj mis, tag nrho 20 fwj hauv ib lub thawv, 180kg / chim, LOSSIS raws li cov neeg siv khoom thov.

    Cia

    - Khaws rau hauv cov thawv ntim covestro qub.
    - Pom zoo cia kub: 10 - 30 ° C.
    - Tiv thaiv los ntawm ya raws, cua sov thiab khoom txawv teb chaws.
    Cov ntaub ntawv dav dav: Thaum lub sijhawm thauj mus los thiab khaws cia ntawm qhov kub thiab txias,crystalline deposits yuav tsim.
    Cov no redissolve nyob rau hauv chav tsev kub. Covcov khoom yog rhiab heev rau cov dej noo thiab hnov ​​​​mob nrog dej los tsim cov pa roj carbondioxide thiab insoluble ureas.
    Yog li ntawd, cov ntim khoom yuav tsum tau ceev kom nrujkaw. Lub ingress ntawm dej nyob rau hauv txhua daim ntawv (dawb ntim, anhydrouscov kuab tshuaj, huab cua noo) yuav tsum tau tiv thaiv raws li txwv tsis pub tsim cov pa roj carbondioxide tej zaum yuav ua rau muaj kev phom sij nyob rau hauv lub siab nyob rau hauv lub ntim.
    Kev raug rau huab cua thiab / lossis lub teeb ua kom muaj xim tsis zoo tab sis qhov no tsis cuam tshuam raucov khoom ua nyob rau hauv dav dav.
