Ukuthengisa Okuqondile Kwemboni Okuthengiswa Kakhulu I-Dimethyl Thio Diamine (DMTDA) CAS 106264-79-3
Sigcizelela inqubekela phambili futhi sethula izixazululo ezintsha emakethe minyaka yonke ye-Best-Selling Factory Direct Sales Dimethyl Thio Diamine (DMTDA) CAS 106264-79-3, Inzuzo nenjabulo yamakhasimende kuhlale kuyinjongo yethu enkulu. Kufanele usithinte. Sinike amathuba, sikunikeze isimanga.
Sigcizelela intuthuko futhi sethula izixazululo ezintsha emakethe minyaka yonke, kufanele uzizwe ukhululekile ukusithumelela izidingo zakho futhi sizokuphendula ngokushesha. Sineqembu lochwepheshe bobunjiniyela elizokusebenzela cishe zonke izidingo zakho ezinemininingwane. Amasampula amahhala angathunyelwa wena mathupha ukuze uqonde ulwazi oluthe xaxa. Ukuze uhlangabezane nezidingo zakho, kufanele uzizwe ukhululekile ukuxhumana nathi. Ungasithumelela ama-imeyili futhi usithinte ngqo. Ngaphezu kwalokho, siyakwamukela ukuvakashelwa efektri yethu evela emhlabeni wonke ukuze siqaphele kangcono inhlangano yethu. Ebhizinisini lethu nabathengisi bamazwe amaningi, sivame ukunamathela esimisweni sokulingana kanye nezinzuzo zombili. Sithemba ngempela ukumaketha, ngemizamo ehlangene, ukuhweba ngakunye kanye nobungane ukuze sizuze sonke. Silangazelela ukuthola imibuzo yakho.
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.
| Ukubukeka | Uketshezi olukhanyayo oluphuzi olubonakalayo |
| Ukuhlolwa kwe-Diamine (GC) | ≥95% |
| Inani Lombala (Umlimi Wengadi) | ≤8 |
| Ukuhlolwa kwe-TDA | ≤0.1% |
| Inani le-Amine | 525-535 |
| Okuqukethwe kwamanzi | ≤0.1% |
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 amine isetshenziswa kabanzi embonini yezindwangu, iphepha kanye nokunyathelisa. I-Dimethyl thio-toluene diamine ingashiwo ukuthi inemakethe ebanzi kusukela embonini yezindiza kanye nezindiza kuya embonini yomphakathi jikelele.
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.
