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.

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.

Packing thiab Cia

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

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

Tag nrho cov Crosslinker series cov khoom yog rhiab heev rau cov dej noo; nws yuav tsim carbon dioxide thiab insoluble urea nyob rau hauv cov tshuaj tiv thaiv nrog dej.

Yog tias raug huab cua los yog lub teeb, nws yuav ua kom cov xim hloov ntawm cov khoom, Tab sis cov tswv yim ua haujlwm yuav tsis cuam tshuam.

Cov ntaub ntawv thauj mus los

1. United Nations tus lej: 1173

2. United Nations Thauj lub npeFlammable kua, tsis tau teev tseg (ethyl acetate, chlorobenzene)

3. Kev pheej hmoo ntawm kev thauj mus los: 3

4. Ntim qeb: II

5. Kev puas tsuaj ib puag ncig: tsis muaj
