Sharaxaadda Badeecada

TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, lambarka CAS 91-97-4, waa wax lagu daro guud oo lagu hagaajinayo sifooyinka farsamada iyo kiimikada ee elastomers-ka urethane. Labada giraan ee benzene ee ku jira molecule-ka TODI waxay leeyihiin qaab-dhismeed siman. Sababtoo ah caqabadda steric ee kooxda o-methyl, dhaqdhaqaaqa falgalka ayaa ka hooseeya kan TDI iyo MDI.

Marka la barbardhigo elastomers-ka polyurethane ee ku salaysan NDI, elastomers-ka ku salaysan TODI, oligomer polyols iyo MOCA waxay leeyihiin sifooyin jireed oo isku mid ah, sida iska caabbinta kulaylka oo aad u fiican, iska caabbinta hydrolysis-ka iyo sifooyinka farsamada. Marka la barbardhigo cinjirka, balaastikada iyo biraha, elastomers-ka ku salaysan TODI waxay leeyihiin faa'iidooyin badan, waa kuwo waara, iska caabbinta kulaylka iyo iska caabbinta hydrolysis-ka. Elastomers-ka ku salaysan TODI waxay bixiyaan sifooyin farsamo oo heer sare ah oo lagu dabaqi karo marka la shaqeynayo xaalado adag iyo/ama deegaan. Intaa waxaa dheer, iyadoo ay ugu wacan tahay cimrigeeda dheriga oo dheer, prepolymer-ka ku salaysan TODI way fududahay in la maareeyo marka la barbar dhigo alaabada ku salaysan NDI.

Codsiga

Iyada oo leh sifooyin farsamo iyo kiimiko oo heer sare ah, elastomers-ka ku salaysan TODI si weyn ayaa loogu dabaqaa meelo kala duwan. Marka hore, qaybaha shaabadaynta, sida shaabadaynta saliidda, giraanta piston, shaabadaynta biyaha iyo wixii la mid ah. Kadib, qaybaha baabuurta waa codsi kale oo weyn oo TODI ah, oo ay ku jiraan fidinta bamperka, nuugayaasha shoogga, dubayaasha iyo iwm. Intaa waxaa dheer, isticmaalka warshadaha ee heer sare ah, tusaale ahaan suunka, duubabka, casters-ka. Intaa waxaa dheer, TODI waa wakiil dahaadh muhiim ah oo ku jira goobta korontada iyo sidoo kale xubnaha macmalka ah ee qalabka caafimaadka.

Baakaynta iyo Kaydinta

Baakad: 50kgs/durbaan bir ah.

Kaydinta iyo rarista: TODI waxay u nugul tahay qoyaanka. Biyuhu waxay la falgalaan dhammaan diisocyanates si ay u sameeyaan wax soo saar urea ah oo aan milmi karin. TODI waa in lagu kaydiyaa weelal si adag loo xiray xaalado qabow oo qalalan.

HA ku darin TODI cuntada oo ha ku soo gelin jawi ka sarreeya 30℃. Ka dib marka la isticmaalo, daboolka waa in isla markiiba la xiraa haddii cillad dhacdo. Xaaladaha kaydinta ee ku habboon, TODI waxay shaqaynaysaa ugu yaraan lix bilood laga bilaabo taariikhda la keenay.
