[Cov Khoom Siv Tshuaj]

Toluene diisocyanate muaj ob hom isomeric (2,4-toluene diisocyanate thiab 2,6-toluene diisocyanate), uas muaj cov khoom zoo sib xws thiab cov teebmeem. Toluene diisocyanate yog tsim tawm hauv kev lag luam ua 80:20 (2,4-toluene diisocyanate:2,6-toluene diisocyanate) sib tov ntawm ob lub isomers. Thaum sov chav tsev, qhov sib tov yog cov kua daj ntshiab, daj ntseg nrog lub ntxhiab tsw ntse. Nws yuav tsum khaws cia rau hauv lub tub yees, deb ntawm lub teeb thiab noo noo hauv lub thawv kaw nruj nreem hauv huab cua inert. Toluene diisocyanate tsis yaj hauv dej thiab sib xyaw nrog feem ntau cov kuab tshuaj organic. Toluene diisocyanate yog tsim los ntawm kev cuam tshuam toluene diamine nrog carbonyl chloride (phosgene). Toluene diisocyanate feem ntau yog siv ua cov tshuaj nruab nrab hauv kev tsim cov polyurethane ua npuas ncauj, elastomers, thiab cov txheej txheej, xim, varnishes, hlau enamels, sealants, adhesives, thiab binders. Nws kuj tseem siv ua tus neeg sawv cev sib txuas hauv kev tsim cov nylon polymers. 2,4-Toluene diisocyanate yog siv ua cov tshuaj nruab nrab hauv kev tsim cov khoom polyurethane, xws li ua npuas ncauj, txheej txheej, thiab elastomers.

[Siv]

Hauv kev tsim cov polyurethane ua npuas ncauj thiab lwm yam elastomers.

Mob hawb pob los ntawm kev ua haujlwm yog qhov ua rau muaj kab mob ua pa hauv ntiaj teb kev lag luam. Toluene-2,4-diisocyanate (TDI) yog ib qho ntawm cov tshuaj ua rau ua pa tsis taus uas ua rau mob hawb pob los ntawm kev ua haujlwm.

TDI (toluene diisocyanate) yog cov khoom siv tseem ceeb ntawm polyurethane. TDI yog kev sib xyaw ntawm 2,4-TDI thiab 2,6-TDI ob hom isomers, suav nrog 3 hom qib siv feem ntau: TDI-80/20, TDI-100 thiab TDI-65/35. Feem ntau siv rau hauv kev tsim cov polyurethane ua npuas ncauj thiab polyurethane elastomer coatings, adhesives, thiab lwm yam.

Toluene-2,4-diisocyanate yog ib qho ntawm cov isocyanates siv dav tshaj plaws. Nws yog siv rau hauv kev tsim cov urethane ua npuas ncauj thiab cov khoom siv tau yooj yim, elastomers, thiab coatings. Ntxiv rau nws siv ua cov tshuaj ntshiab, nws muaj nyob rau hauv kev lag luam ua cov khoom sib xyaw ntawm 2,4- thiab 2,6-isomers (80: 20% thiab 65: 35% piv, feem).
