    Khoom Properties & Features

    Desmodur RE yog tus neeg sawv cev sib txuas ua haujlwm zoo heev, Siv rau hauv cov nplaum ua los ntawm hydroxyl polyurethane, natural los yog hluavtaws roj hmab,

    Nws muaj kev sib raug zoo heev lub zog hauv roj hmab thiab cab yuav siv tau rau hauv resin, antioxidant, plasticizing tus neeg sawv cev, siab-rhiab thiab lwm yam.

    Nws tuaj yeem siv los ua crosslinker hloov BAYER's Desmodur RE

    RE 1

    Kev siv

    Ob daim nplaum nplaum yuav tsum tau siv nyob rau hauv lub sijhawm siv tau tom qab muab tso rau hauv RE.

    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 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%), RE koob 4-7. chloroprene roj hmab (Rubber account rau ib ncig ntawm 20%), RE ua 4-7.

    RE 2

    Cia

    Thov khaws cia rau hauv lub thawv ntim thawj hauv qab 23 ℃, cov khoom tuaj yeem khaws cia ruaj khov rau 12 lub hlis.

    Nws rhiab heev rau feem ntau; nws yuav tsim carbon dioxide thiab insoluble urea nyob rau hauv cov tshuaj tiv thaiv nrog dej.

    Yog tias raug teh huab cua lossis lub teeb, nws yuav ua kom cov xim hloov pauv sai, tab sis qhov kev ua tau zoo yuav tsis cuam tshuam.

    Pob

    750 g / lub raj mis lossis 50 kg / nruas lossis 180 kg / nruas lossis raws li tus neeg yuav tsum tau ua.
