Chii chinonzi Dimethyl thio-toluene Diamine DMTDA?

DMTDA rudzi rutsva rwe polyurethane elastomer kurapa uye crosslinking agent, umo mune kunyanya maviri isomers, kureva musanganiswa we 2,4 - uye 2,6 - dimethylthiotoluene diamine (reshiyo inosvika 77~80/17~20). Kana ichienzaniswa neinowanzo shandiswa MOCA, DMTDA imvura ine yakaderera viscosity pane yakajairika tembiricha, inogona kushandiswa pakuvaka basa pakadzika tembiricha, uye ine yakaderera kemikari yakaenzana.

Application

1. Iri rudzi rutsva rwemvura inorapa agent ye polyurethane elastomer. Inoshandiswa zvakanyanya mu polyurethane casting, coating, RIM, SPUA, polyurethane tyre uye adhesive yekuwedzera cheni kana kuyambuka-kubatanidza, uye zvakare inorapa epoxy resin.

2. Sekuoma, kana yakawedzerwa kuTDI neMTDI maviri-liquid polyurethane elastomers, inofanira kuwedzerwa pamwero we10%. Mukugadzira uye indasitiri yehurumende, inowanzoshandiswa sechinhu chinowedzera chekuputira moto (layer pamusoro uye madziro emadziro), kuchengetedzwa kwekuora kwezvinhu zvesimbi (kupfekedza pamadziro emukati wepombi yesimbi), nezvimwe zvinhu. Iyo polyurethane chigadzirwa chinogona kuita nezvimwe zvinhu pasina chero kurapwa chakakwirira kune chigadzirwa cheMOCA (Mocha) hardener.
3. Inoshandiswa ku polyurethane kudhinda rubber scraper, mafuta pombi yekuchenesa scraper, nezvimwewo, kuvandudza kupikisa kwemafuta e polyurethane, uye kuwedzera kwehuwandu hwehuwandu hwakaderera zvakare.
4. Mukuwedzera, inoshandiswa zvakanyanya mumucheka, mapepa uye maindasitiri ekudhinda. Zvinogona kutaurwa kuti ine musika wakafara kubva kune indasitiri yendege uye yezvemuchadenga kuenda kune yakajairika indasitiri indasitiri.
