Yintoni iDimethyl thio-toluene Diamine DMTDA?

I-Dimethyl thio-toluene diamine (DMTDA), enenombolo ye-CAS engu-106264-79-3, yinxalenye ebalulekileyo ye-organic. Ii-athomu zesalfure kwimolekyuli ye-amine ye-DMTDA zinokuphucula amandla okudibanisa neesinyithi, kwaye kwangaxeshanye zinike imveliso ephilisiweyo ukumelana okuhle kakhulu ne-hydrolysis kunye nokumelana nokugqwala kweekhemikhali.

I-DMTDA luhlobo olutsha lwe-polyurethane elastomer curing and crosslinking agent, apho kukho ii-isomers ezimbini ikakhulu, ezizezi umxube we-2,4 – kunye ne-2,6 – dimethylthiotoluene diamine (umlinganiselo umalunga ne-77 ~ 80/17 ~ 20). Xa kuthelekiswa ne-MOCA esetyenziswa rhoqo, i-DMTDA lulwelo olune-viscosity ephantsi kubushushu obuqhelekileyo, olunokusetyenziselwa umsebenzi wokwakha kubushushu obuphantsi, kwaye lune-chemical equivalent ephantsi.

Isicelo

1. I-Dimethyl thio-toluene diamineluhlobo olutsha lwearhente yokunyanga ulwelo kwi-polyurethane elastomer. I-Dmtda amine isetyenziswa kakhulu kwi-polyurethane casting, coating, RIM, SPUA, polyurethane tire kunye ne-adhesive yokwandisa ityathanga okanye ukudibanisa, kwaye ikwayiarhente yokunyanga i-epoxy resin.

2. I-Dmtda ethacure 300 yiarhente yokunyanga i-epoxy resin kwaye ingasetyenziselwa ukuphucula ukusebenza kwe-epoxy resin.

3. Njenge-hardenener, xa yongezwa kwi-TDI kunye ne-MTDI two-liquid polyurethane elastomers, kufuneka yongezwe ngesantya se-10%. Kwishishini lokwakha kunye nelokwakha, i-dmtda amine idla ngokusetyenziswa njengesongezelelo sokufaka umtshiso (udonga oluphezulu nolusecaleni), ukhuseleko lokugqwala kwezinto zesinyithi (udonga olungaphakathi lombhobho wesinyithi), kunye nezinye izinto. Imveliso ye-polyurethane enokusabela nezinye izinto ngaphandle konyango ingcono kunemveliso ye-MOCA (Mocha) hardener.

4. Isetyenziselwa ukukrazula irabha yokuprinta i-polyurethane, ukukrazula ipayipi yeoyile, njl.njl., ukuphucula ukumelana neoyile ye-polyurethane, kwaye izinga lokwandiswa komthamo nalo liphantsi.

5. Ukongeza, i-dmtda amineIsetyenziswa kakhulu kwimizi-mveliso yelaphu, iphepha kunye nokushicilela. I-Dimethyl thio-toluene diamine ingatsho ukuba inemarike ebanzi ukusuka kwimizi-mveliso yeenqwelo moya kunye neenqwelo moya ukuya kwimizi-mveliso yoluntu ngokubanzi.

Iingenelo zethu

1. Umxholo wethu we-DMTDA udlula kakhulu imigangatho yoshishino, kwaye ibhetshi nganye ifikelela ngaphezulu kwama-96%.

2. Ixabiso le-amine liphezulu kuneemilinganiselo zoshishino, ibhetshi nganye ifikelela kwi-530mgKOH/g ngokuzinzileyo, nto leyo enika ukusebenza okugqwesileyo kokuphilisa.

3. Sinemveliso eyaneleyo kunye nesitokhwe esitsha, siqinisekisa ukuzaliseka kweodolo ngokukhawuleza, kunye nokuhanjiswa okunokwenzeka kwiintsuku ezi-5 zokusebenza.

4.Ngaphandle kokupakisha kwethu okuqhelekileyo kwe-200kg yeedrama, sinikezela ngeendlela zokupakisha ezenziwe ngokwezifiso kunye neenkonzo zokuprinta iilogo ezenzelwe iimfuno zakho ezithile.
