Peb lub RE, tseem hu ua TTI, yog ib qho tshuaj uas muaj 27.5% triphenylmethane-4,4ˊ,4〞-triisocyanate thiab 72.5% ethyl acetate. Nws yog ib qho tshuaj kho/crosslinker rau cov nplaum uas ua los ntawm hydroxyl polyurethane, roj hmab ntuj thiab roj hmab hluavtaws, tshwj xeeb tshaj yog zoo rau kev sib txuas cov khoom siv roj hmab. Nws kuj siv dav rau kev sib txuas cov hlau nrog roj hmab. Ntxiv mus, RE tuaj yeem siv rau cov resin, antioxidant, plasticizer, thiab lwm yam. Hauv kev sib txuas nplaum, RE yog siv ua tus neeg sawv cev sib txuas ntawm cov nplaum neoprene thiab/lossis p hydroxyl polyurethane nplaum hauv thaj chaw khau. Feem ntau, rau kev kho cov nplaum ntawm 100 qhov los ntawm qhov hnyav (pbw) raws li qhov ntau ntawm 4-7 pbw RE pom zoo. Lub sijhawm siv ntawm cov nplaum sib xyaw yog kwv yees li ob peb teev.
Cov nplaum ob yam yuav tsum tau siv rau hauv lub sijhawm siv tau tom qab muab RE tso rau hauv. Lub sijhawm siv tau tsis yog tsuas yog cuam tshuam nrog cov polymer hauv cov nplaum xwb, tab sis kuj tseem muaj lwm yam khoom tseem ceeb (xws li resin, antioxygen, plasticizer, solvent, thiab lwm yam). Thaum ze rau lub sijhawm siv tau, feem ntau yog ob peb teev lossis ib hnub ua haujlwm, cov nplaum yuav nyuaj rau ua haujlwm, thiab viscosity nce sai sai. Thaum kawg, Nws dhau los ua cov kua nplaum uas tsis hloov pauv tau. 100 cov nplaum zoo, Hydroxyl polyurethane (Polyurethane suav txog li 20%), RE koob tshuaj 4-7. Chloroprene roj hmab (Roj hmab suav txog li 20%), Peb RE ua 4-7.

750g/lub raj mis, 20 lub raj mis hauv ib lub thawv, 24 lossis 30 lub thawv hauv ib lub pallet;
20kg/nruas, 18 nruas lossis 27 nruas hauv ib lub pallet;
55kg/nruas, 8 lossis 12 nruas hauv ib lub pallet;
180kg/nruas, 4 nruas hauv ib lub pallet
Kev Khaws Cia:
Thov khaws cia rau hauv lub thawv kaw thawj zaug hauv qab 23 ℃, cov khoom tuaj yeem khaws cia ruaj khov rau 12 lub hlis. Nws rhiab heev rau cov av noo; nws yuav tsim cov pa roj carbon dioxide thiab cov urea uas tsis yaj hauv cov tshuaj tiv thaiv nrog dej. Yog tias raug cua lossis lub teeb, nws yuav ua rau cov xim hloov pauv sai dua, tab sis kev ua haujlwm yuav tsis cuam tshuam.
