Tolidine diisocyanate TODI / 3,3′-Dimethyl-4,4′-biphenylene diisocyanate CAS OYA. 91-97-4
TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, CAS nimero 91-97-4, ni inyongeramusaruro rusange yo kunoza imiterere ya mashini na chimique kuri elastomers ya urethane. Impeta ebyiri za benzene muri molekile ya TODI zifite imiterere ihuriweho. Bitewe nimbogamizi zidasanzwe zitsinda o-methyl, ibikorwa byitwara biri munsi yibya TDI na MDI.
Ugereranije na NDI ishingiye kuri polyurethane elastomers, elastomers ishingiye kuri TODI, oligomer polyols na MOCA bifite imiterere isa nkumubiri, nko kurwanya ubushyuhe bwiza, kurwanya hydrolysis hamwe nubukanishi. Ugereranije na reberi, plastike nicyuma, elastomers ishingiye kuri TODI ifite ibyiza byinshi, biraramba, birwanya ubushyuhe hamwe na hydrolysis irwanya. TODI ishingiye kuri elastomers itanga imashini isumba iyindi ikoreshwa mugukora mubihe bibi kandi / cyangwa ibidukikije. Byongeye kandi, bivuye mubuzima burebure bwinkono, TODI ishingiye kuri prepolymer iroroshye kubyitwaramo ugereranije nibicuruzwa bishingiye kuri NDI.
Hamwe nimikorere yihariye ya mashini na chimique, TODI ishingiye kuri elastomers ikoreshwa cyane mubice bitandukanye. Mbere ya byose, gufunga ibice, nko gufunga amavuta, impeta ya piston, kashe y'amazi nibindi. Noneho, ibice byimodoka nubundi buryo bukoreshwa bwa TODI, harimo kwagura bumper, imashini itwara imashini, grilles nibindi. Byongeye kandi, TODI nigikoresho cyingenzi cyo gutwika mumashanyarazi kandi nkibice byubukorikori mubikoresho byubuvuzi.
Gupakira: 50kgs / ingoma y'icyuma.
Kubika no gutwara: TODI yunvikana nubushuhe. Amazi akora hamwe na diisocyanate yose kugirango akore ibiva muri urea. TODI igomba kubikwa mubintu bifunze neza mubihe bikonje kandi byumye.
Ntugashyire TODI hamwe nibiryo kandi wirinde kwerekana ahantu hejuru ya 30 ℃. Nyuma yo gukoresha, umupfundikizo ugomba guhita ufungwa mugihe habaye imikorere mibi. Mugihe gikwiye cyo kubika, TODI ifite agaciro mumezi atandatu byibuze ikurikizwa guhera umunsi yatangiwe.
