Waa maxay Dimethyl thio-toluene Diamine DMTDA?

Dimethyl thio-toluene diamine (DMTDA), oo leh lambarka CAS 106264-79-3, waa isku-dhis muhiim ah oo dabiici ah. Atomyada sulfur-ka ee ku jira molecule-ka amine-ka DMTDA waxay kor u qaadi karaan awoodda isku-dubaridka biraha, isla markaana waxay siiyaan badeecada la daaweeyay iska caabin hydrolysis oo heer sare ah iyo iska caabinta daxalka kiimikada.

DMTDA waa nooc cusub oo ah polyurethane elastomer curing and crosslinker agent, kaas oo ay ku jiraan inta badan laba isomers, kuwaas oo ah isku darka 2,4 – iyo 2,6 – dimethylthiotoluene diamine (saamiga waa qiyaastii 77~80/17~20). Marka la barbardhigo MOCA-da caadiga ah ee la isticmaalo, DMTDA waa dareere leh viscosity hooseeya heerkulka caadiga ah, kaas oo loo isticmaali karo hawlgalka dhismaha heerkulka hooseeya, wuxuuna leeyahay kiimiko hoose oo u dhiganta.

Codsiga

1. Dimethyl thio-toluene diaminewaa nooc cusub oo ah wakiilka daaweynta dareeraha ah ee polyurethane elastomer. Dmtda amine waxaa si weyn loogu isticmaalaa shubka polyurethane, dahaarka, RIM, SPUA, taayirka polyurethane iyo dhejiska loogu talagalay fidinta silsiladda ama isku xidhka, waana sidoo kale wakiilka daaweynta ee epoxy resin.

2. Dmtda ethacure 300 waa walax daaweyn u ah resin epoxy waxaana loo isticmaali karaa in lagu hagaajiyo waxqabadka resin epoxy.

3. Adkayn ahaan, marka lagu daro TDI iyo MTDI laba-dareere polyurethane ah, waa in lagu daraa heerka 10%. Warshadaha dhismaha iyo kuwa madaniga ah, dmtda amine waxaa badanaa loo isticmaalaa sidii lagu daro dahaarka dabka ka hortaga (lakabka sare iyo derbiga dhinaca), ilaalinta daxalka ee agabka birta (dahaarka derbiga gudaha ee tuubada birta), iyo dhinacyo kale. Badeecada polyurethane ee la falgeli karta walxaha kale iyada oo aan wax daaweyn ah la helin ayaa ka sarreysa badeecadaha adag ee MOCA (Mocha).

4. Waxaa loo isticmaalaa xoqidda caagga ah ee daabacaadda polyurethane, xoqidda nadiifinta tuubooyinka saliidda, iwm., si loo hagaajiyo iska caabbinta saliidda ee polyurethane, heerka ballaarinta muggana sidoo kale waa hooseeyaa.

5. Intaa waxaa dheer, dmtda aminewaxaa si weyn looga isticmaalaa warshadaha dharka, warqadda iyo daabacaadda. Dimethyl thio-toluene diamine waxaa la dhihi karaa wuxuu leeyahay suuq ballaaran laga bilaabo warshadaha duulista iyo hawada ilaa warshadaha madaniga ah ee guud.

Faa'iidooyinka aan leenahay

1. Mawduucayaga DMTDA aad ayuu uga sarreeyaa heerarka warshadaha, iyadoo dufcad kasta ay si joogto ah u gaarto in ka badan 96%.

2. Iyada oo ku faanaysa qiimaha amiin-ka oo ka sarreeya heerarka warshadaha, dufcad kasta waxay si joogto ah u gaartaa 530mgKOH/g, taasoo bixinaysa waxqabad daaweyn oo heer sare ah.

3. Iyada oo leh awood wax soo saar oo ku filan iyo kayd cusub, waxaan dammaanad qaadaynaa fulinta dalabka oo degdeg ah, iyadoo keenistu la gaari karo 5 maalmood gudahood.

4. Marka laga reebo baakadaha durbaanka ee 200kg ee caadiga ah, waxaan bixinaa ikhtiyaarrada baakadaha gaarka ah iyo adeegyada daabacaadda astaanta ee loogu talagalay baahiyahaaga gaarka ah.
