Iyini i-Dimethyl thio-toluene Diamine DMTDA?

I-DMTDA iwuhlobo olusha lwe-polyurethane elastomer elaphayo kanye ne-crosslinking agent, lapho kukhona khona ikakhulukazi ama-isomer amabili, okuyingxube ye-2,4 – kanye no-2,6 – dimethylthiotoluene diamine (isilinganiso silinganiselwa ku-77~80/17~20). Uma kuqhathaniswa ne-MOCA evame ukusetshenziswa, i-DMTDA iwuketshezi olune-viscosity ephansi ekushiseni okujwayelekile, engasetshenziselwa umsebenzi wokwakha ekushiseni okuphansi, futhi inokulingana kwamakhemikhali aphansi.

Ukucaciswa

Isicelo

1. Iwuhlobo olusha lwe-ejenti yokwelapha uketshezi ye-polyurethane elastomer. Isetshenziswa kabanzi ekubunjweni kwe-polyurethane, ukunamathela, i-RIM, i-SPUA, isondo le-polyurethane ne-adhesive yokwandiswa kwamaketanga noma ukuxhumanisa, futhi iyi-ejenti yokwelapha ye-epoxy resin.

2. Njenge-hardener, uma yengezwe ku-TDI kanye ne-MTDI ye-polyurethane elastomers enamanzi amabili, kufanele yengezwe ngesilinganiso esingu-10%. Embonini yokwakha kanye neyomphakathi, ivame ukusetshenziswa njengesengezo sokumboza umlilo (ungqimba olungaphezulu nodonga olusemaceleni), ukuvikelwa kokugqwala kwezinto zensimbi (ukugqoka odongeni lwangaphakathi lwepayipi yensimbi), nezinye izici. Umkhiqizo we-polyurethane ongasabelana nezinye izinto ngaphandle kwanoma yikuphi ukwelashwa uphakeme kunomkhiqizo we-MOCA (Mocha) hardener.
3. Isetshenziselwa i-polyurethane yokunyathelisa i-rubber scraper, i-oil pipe yokuhlanza i-scraper, njll, ukuze kuthuthukiswe ukumelana kwamafutha e-polyurethane, futhi izinga lokunwetshwa kwevolumu liphansi.
4. Ngaphezu kwalokho, isetshenziswa kakhulu ezimbonini zendwangu, iphepha kanye nokunyathelisa. Kungashiwo ukuthi inemakethe ebanzi kusukela embonini yezindiza kanye ne-aerospace kuya embonini yomphakathi jikelele.
