Waa maxay Dimethyl thio-toluene Diamine DMTDA?

DMTDA waa nooc cusub oo ah daaweynta elastomer poliurethane iyo wakiilka isdhaafsiga, kaas oo ay ku jiraan inta badan laba isomers, kuwaas oo ah isku dhafka 2,4 - iyo 2,6 - dimethylthiotoluene diamine (saamiga waa qiyaastii 77 ~ 80/17 ~ 20). Marka la barbar dhigo MOCA-ga caadiga ah, DMTDA waa dareere leh viscosity hooseeya heerkulka caadiga ah, kaas oo loo isticmaali karo hawlgalka dhismaha heerkulka hooseeya, oo leh kiimiko hoose oo u dhigma.

Codsiga

1. Waa nooc cusub oo ah wakiilka daawaynta dareeraha ee elastomer polyurethane. Waxaa si weyn loogu isticmaalaa shubista poliurethane, dahaarka, RIM, SPUA, taayirka poliurethane iyo koollada loogu talagalay fidinta silsiladda ama isku-xidhka, iyo sidoo kale wakiilka daweynta ee resin epoxy.

2. Sida adag, marka lagu daro TDI iyo MTDI laba-dareere poliurethane elastomers, waa in lagu daraa heerka 10%. Dhismaha iyo warshadaha madaniga ah, waxaa badanaa loo isticmaalaa sida wax lagu daro oo loogu talagalay dahaarka dabka (lakabka sare iyo darbiga dhinaca), ilaalinta daxalka ee alaabta birta ah (dahaarka gidaarka gudaha ee tuubada birta), iyo dhinacyo kale. Alaabta poliurethane ee ka falcelin karta walxaha kale iyada oo aan wax daaweyn ah la helin ayaa ka sarreeya sheyga MOCA (Mocha).
3. Waxaa loo isticmaalaa qashinka daabacaadda poliurethane, qashinka nadiifinta tuubada saliidda, iwm, si loo hagaajiyo caabbinta saliidda ee poliurethane, iyo heerka fidinta mugga ayaa sidoo kale hooseeya.
4. Intaa waxaa dheer, si weyn loogu isticmaalo warshadaha dunta, waraaqaha iyo daabacaadda. Waxa la odhan karaa waxa ay leedahay suuq balaadhan laga soo bilaabo warshadaha duulista iyo hawada ilaa warshadaha madaniga ah ee guud.
