TDI -80/20 (toluene diisocyanate) yog ib qho uas nquag siv polyisocyanate, feem ntau yog siv rau hauv kev npaj cov ntaub ntawv polyurethane (PU). TDI-80/20 yog sib xyaw ntawm 2,4-toluene diisocyanate thiab 2,6-toluene diisocyanate, ntawm 2,4-TDI suav rau 80% thiab 2,{ {12}}TDI suav rau 20%.
Kev siv tseem ceeb ntawm toluene diisocyanate yog:
1. Kev npaj ntawm cov ntaub ntawv polyurethane: TDI -80/20 yog ib qho ntawm cov khoom siv raw khoom siv hauv kev lag luam polyurethane, feem ntau yog siv los tsim cov polyurethane ua npuas ncauj, polyurethane elastomer, coatings, adhesives, thiab lwm yam.
2. Protein cross-linking: Raws li covalent cross-linking tus neeg saib xyuas rau cov protein, nws yog siv hauv kev tshawb fawb biochemical.
3. Antibody fixation: Kho cov tshuaj tiv thaiv kab mob ntawm cov yas yas rau radioimmunoassay.
TDI -80/20 yog cov kua tsis muaj xim nrog cov ntxhiab tsw ntxhiab thiab hloov xim nyob rau hauv tshav ntuj. Nws tuaj yeem cuam tshuam nrog dej los tsim cov pa roj carbon dioxide thiab soluble hauv cov kuab tshuaj organic xws li ethanol thiab acetone. Thaum khaws cia, nws yuav tsum tau ntim nrog argon lossis nitrogen thiab khaws cia kom deb ntawm lub teeb.
TDI-80/20 yog tshuaj lom neeg thiab tej zaum yuav muaj kev cuam tshuam rau tib neeg kev noj qab haus huv. Thov ua tib zoo saib xyuas kev tiv thaiv thaum siv nws. Cov neeg muas zaub uas xav yuav TDI-80/20, thov hu rau peb lub tuam txhab, peb yuav muab cov khoom zoo thiab cov kev pab cuam rau koj.
