Iyini i-Dimethyl thio-toluene Diamine DMTDA?

I-Dimethyl thio-toluene diamine (DMTDA), enenombolo ye-CAS engu-106264-79-3, iyinhlanganisela ebalulekile yezinto eziphilayo. Ama-athomu esibabule ku-molecule ye-amine ye-DMTDA angathuthukisa ikhono lokuxhumana nezinsimbi, futhi ngesikhathi esifanayo anikeze umkhiqizo osuqediwe ukumelana okuhle kakhulu kwe-hydrolysis kanye nokumelana nokugqwala kwamakhemikhali.

I-DMTDA uhlobo olusha lwe-polyurethane elastomer curing and crosslinking agent, lapho kukhona khona ama-isomer amabili ikakhulukazi, okuyingxube ye-2,4 - kanye ne-2,6 - dimethylthiotoluene diamine (isilinganiso singama-77 ~ 80/17 ~ 20). Uma kuqhathaniswa ne-MOCA evame ukusetshenziswa, i-DMTDA iwuketshezi olune-viscosity ephansi ekushiseni okujwayelekile, olungasetshenziswa ekusebenzeni kokwakha ekushiseni okuphansi, futhi lunokulingana kwamakhemikhali okuphansi.

Imininingwane

Ukuhlolwa kwe-Diamine (GC)	≥95%
Inani Lombala (Umlimi Wengadi)	≤8
Ukuhlolwa kwe-TDA	≤0.1%
Inani le-Amine	525-535
Okuqukethwe kwamanzi	≤0.1%

Isicelo

1. I-Dimethyl thio-toluene diamineuhlobo olusha lwe-ejenti yokwelapha uketshezi ye-polyurethane elastomer. I-Dmtda amine isetshenziswa kabanzi ekubunjweni kwe-polyurethane, ekumbozeni, e-RIM, e-SPUA, ethayini le-polyurethane kanye ne-adhesive yokwelulwa kweketanga noma ukuxhumanisa, futhi futhi iyi-ejenti yokwelapha ye-epoxy resin.

2. I-Dmtda ethacure 300 iyi-ejenti yokwelapha i-epoxy resin futhi ingasetshenziswa ukuthuthukisa ukusebenza kwe-epoxy resin.

3. Njenge-hardener, uma ingezwa kuma-TDI kanye nama-MTDI two-liquid polyurethane elastomers, kumele ifakwe ngesilinganiso esingu-10%. Embonini yokwakha kanye neyomphakathi, i-dmtda amine ivame ukusetshenziswa njengesithasiselo sokugqoka okungashi (ungqimba oluphezulu nodonga oluseceleni), ukuvikelwa kokugqwala kwezinto zensimbi (ukugqoka odongeni lwangaphakathi lwepayipi lensimbi), kanye nezinye izici. Umkhiqizo we-polyurethane ongasabela nezinye izinto ngaphandle kokwelashwa ungcono kunomkhiqizo we-hardener ye-MOCA (Mocha).

4. Isetshenziselwa ukuskena irabha yokunyathelisa i-polyurethane, ukuskena ipayipi likawoyela, njll., ukuthuthukisa ukumelana kukawoyela kwe-polyurethane, futhi izinga lokunwetshwa kwevolumu nalo liphansi.

5. Ngaphezu kwalokho, i-dmtda amineisetshenziswa kabanzi embonini yezindwangu, iphepha kanye nokunyathelisa. I-Dimethyl thio-toluene diamine ingashiwo ukuthi inemakethe ebanzi kusukela embonini yezindiza kanye nezindiza kuya embonini yomphakathi jikelele.

Izinzuzo zethu

1. Okuqukethwe kwethu kwe-DMTDA kudlula kakhulu amazinga embonini, kanti ibhetshi ngayinye ifinyelela ngaphezu kwama-96%.

2. Njengoba inenani le-amine eliphakeme kunezilinganiso zomkhakha, ibhetshi ngalinye lifinyelela kahle ku-530mgKOH/g, okuletha ukusebenza okuhle kakhulu kokuphilisa.

3. Njengoba sinamandla okukhiqiza anele kanye nesitoko esisha, siqinisekisa ukugcwaliswa kwe-oda okusheshayo, ngokulethwa okufinyelelekayo zingakapheli izinsuku ezi-5 zokusebenza.

4.Ngaphandle kokupakisha kwethu okujwayelekile kwe-drum okungu-200kg, sinikeza izinketho zokupakisha ezenziwe ngokwezifiso kanye nezinsizakalo zokuphrinta amalogo ezenzelwe izidingo zakho ezithile.
