Dimethyl Thio -toluene Diamine / DMTDA CAS 106264-79-3

1. Dimethyl thio-toluene diamine feem ntau yog siv los ua qhov qis- toxicity, kua diamine chain extender thiab kho tus neeg sawv cev rau polyurethane elastomers, ua lwm txoj kev nyab xeeb rau MOCA (4,4'-methylene-bis (2-chloroaniline additives) rau chav tsev kom zoo dua.
2. Cov khoom sib xyaw ua haujlwm ua cov tshuaj tua kab mob hauv cov tshuaj tsuag polyurea elastomers (SPUA), cov tshuaj tiv thaiv kev txhaj tshuaj molding (RIM), thiab siab -cov txheej txheem ua tau zoo, qhov twg DMTDA CAS 106264-79-3 imparts zoo heev txhua yam khoom nrog rau tensile zog, abrasion tsis kam, thiab tshuaj tiv thaiv.
3. DMTDA yog ua hauj lwm los ua ib tug curing agent rau epoxy resins thiab nyob rau hauv lub formulation ntawm siab - muaj zog adhesives thiab sealants rau daim ntawv thov nyob rau hauv lub tsheb, aerospace, kev tsim kho, mining, thiab electronics industries.
4. Hauv cov ntawv thov polyurethane, DMTDA tuaj yeem sib xyaw nrog lwm cov kua amines xws li DETDA los kho cov nqi kho thiab lub sijhawm ua haujlwm, muab cov qauv hloov pauv kom ua tiav cov txheej txheem tshwj xeeb thiab cov cuab yeej cuab tam.

1. Dimethyl thio-toluene diamine yuav tsum muab khaws cia rau hauv lub thawv kaw nruj nreem nyob rau hauv qhov chaw txias, qhuav, thiab zoo- qhov cua nyob ib puag ncig, tiv thaiv los ntawm lub teeb thiab cua sov; pom zoo cia qis dua 15℃hauv qhov chaw txias, tsaus, nrog rau lub neej txee ntawm 1 xyoos.
2. DMTDA CAS 106264-79-3 yog cais nrog GHS cov lus hais txog kev phom sij H302 (Kev phom sij yog tias nqos), H317 (Tej zaum yuav ua rau muaj kev tsis haum rau ntawm daim tawv nqaij), thiab H410 (muaj tshuaj lom heev rau cov dej hauv lub neej nrog cov teebmeem ntev), nrog cov teeb liab lo lus "Warning".
3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg- cov hnab looj tes tiv thaiv (nitrile lossis neoprene), tsom iav kev nyab xeeb nrog sab - cov ntaub thaiv npog, thiab cov khaub ncaws tiv thaiv thaum tuav cov khoom no; tsis txhob ua pa tsw phem lossis vapors thiab ua kom muaj cua txaus hauv chaw ua haujlwm.
4. Khaws DMTDA CAS 106264-79-3 kom deb ntawm cov khoom siv tsis sib xws xws li cov tshuaj muaj zog oxidizing, muaj zog acids, thiab cov hauv paus muaj zog los tiv thaiv decomposition. Khaws cia nyias ntawm cov khoom ntim khoom noj thiab tsis txhob tso tawm rau ib puag ncig.

1. Tshem tawm qhov chaw nchuav, ua kom muaj cua txaus, thiab hnav cov khoom tiv thaiv tus kheej tag nrho nrog rau cov tshuaj lom neeg - cov hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab lub tshuab ua pa tsim nyog thaum ntxuav DMTDA .
2. Sau DMTDA CAS 106264-79-3 los ntawm absorbing nrog inert absorbent cov ntaub ntawv xws li xuab zeb, vermiculite, los yog diatomaceous lub ntiaj teb siv cov cuab yeej uas tsis yog-sparking, thiab muab tso rau hauv lub ntim kaw tsim nyog rau pov tseg.
3. Tsis txhob tsim cov txaws lossis pos huab thaum ntxuav kom tsis txhob raug rau ntawm daim tawv nqaij thiab qhov muag; tiv thaiv cov khoom los ntawm kev nkag mus rau hauv cov kav dej, cov kav dej, lossis cov chav dej vim muaj dej toxicity siab.
4. Pov tseg cov ntaub ntawv khaws tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig los ntawm kev tso cai rau kev puas tsuaj los yog tshuaj tua hluav taws. Cov ntim khoom tsis huv yuav tsum tau muab yaug peb zaug thiab muab rau kev rov ua dua lossis pov tseg hauv qhov chaw huv huv.

1. Dimethyl thio-toluene diamine tsis raug cais raws li cov nplaim taws (flash point 163-176 degree) tab sis yuav decompose nyob rau hauv hluav taws kub siab tshaj 225 degree, emitting pa phem xws li carbon monoxide, carbon dioxide, nitrogen oxides, thiab sulfur oxides.
2. Siv cov hmoov qhuav qhuav, carbon dioxide, cawv- ua npuas dej tiv taus, lossis tshuaj tsuag dej los tua hluav taws uas cuam tshuam nrog cov khoom. Tsis txhob siv lub dav hlau dej ncaj qha raws li DMTDA CAS 106264-79-3 tuaj yeem tawg cov khoom tawg.
3. Cov neeg tua hluav taws yuav tsum hnav tus kheej- muaj cov cuab yeej ua pa (SCBA) hauv siab- thov, NIOSH- tau pom zoo, thiab cov iav tiv thaiv tag nrho thaum tuav cov hluav taws kub uas muaj cov khoom sib xyaw no vim muaj cov pa phem uas tsim tawm thaum lub sij hawm thermal decomposition .
4. Thaum lub sij hawm combustion, tej zaum yuav emit irritant thiab toxic fumes; muaj hluav taws kub los tiv thaiv ib puag ncig. Tsis txhob tso cov dej tua pov tseg rau hauv cov dej ntws los yog cov dej hauv cov dej vim muaj dej toxicity.
