Yintoni iDimethyl thio-toluene Diamine DMTDA?

I-DMTDA luhlobo olutsha lwe-polyurethane elastomer yokunyanga kunye ne-agent edibanisayo, apho kukho ubukhulu becala isomers ezimbini, ezizezi umxube we-2,4 - kunye ne-2,6 - i-dimethylthiotoluene diamine (umlinganiselo umalunga ne-77 ~ 80 / 17 ~ 20).Xa kuthelekiswa ne-MOCA esetyenziswa ngokuqhelekileyo, i-DMTDA iyilwelo kunye ne-viscosity ephantsi kwiqondo lokushisa eliqhelekileyo, elingasetyenziselwa umsebenzi wokwakha kwiqondo lokushisa eliphantsi, kwaye linomlinganiselo ophantsi weekhemikhali.

Isicelo

1. Luhlobo olutsha lwe-arhente yokunyanga ulwelo lwe-polyurethane elastomer.Isetyenziswa ngokubanzi kwi-polyurethane casting, i-coating, i-RIM, i-SPUA, ivili le-polyurethane kunye ne-adhesive kwi-chain extension okanye i-cross-linking, kwaye ikwayi-arhente yokunyanga i-epoxy resin.

2. Njenge-hardener, xa idityaniswe kwi-TDI kunye ne-MTDI i-polyurethane elastomers ebili-liquid, mayifakwe kwireyithi ye-10%.Kwishishini lokwakha kunye neloluntu, lihlala lisetyenziswa njengesongezo sokugquma umlilo (umphezulu kunye nodonga olusecaleni), ukukhuselwa kwe-corrosion yezixhobo zetsimbi (ukugquma eludongeni lwangaphakathi lombhobho wentsimbi), kunye neminye imiba.Imveliso ye-polyurethane enokuthi isebenze kunye nezinye izinto ngaphandle konyango iphezulu kwimveliso ye-MOCA (Mocha) i-hardener.
3. Isetyenziselwa i-polyurethane yokushicilela i-rubber scraper, i-oil pipe yokucoca i-scraper, njl., Ukuphucula ukuxhathisa kweoli ye-polyurethane, kwaye izinga lokwandiswa kwevolumu liphantsi.
4. Ukongeza, isetyenziswa kakhulu kumashishini e-textile, amaphepha kunye nokushicilela.Kunokuthiwa inemakethi ebanzi ukusuka kwishishini lenqwelomoya kunye ne-aerospace ukuya kwishishini loluntu ngokubanzi.
