I-DiMethylthiotoluenediaMine (DMTDA) cas 106264-79-3
DimethylthioToluene Diamie / DMTDA, inombolo yeCAS. 106264-79-3, lunyango lwe-diamines kuzo zombini iinkqubo ze-TDI kunye ne-MDI. Ukuba lulwelo lwe-viscous kwiqondo lobushushu begumbi kukhokelela kuncedo olubalulekileyo lokusetyenzwa, oko kukuthi, ukudluliselwa ngokulula, ukulungele ukusetyenziswa ngaphandle kokunyibilikisa izinto eziqinileyo njenge-MOCA. I-DMTDA yinto efanelekileyo yokunyanga esetyenziselwa ukwenza i-polyurethane/polyurea elastomers ehlala ixesha elide kwaye eguquguqukayo.
I-DMTDA inokuba zombini i-agent ephilisayo kunye ne-chain extender ye-disocyanate pre-polymers, ngakumbi kwinkqubo ye-polyurea ebonelela ngeempawu ezilungileyo zoomatshini kunye neziguquguqukayo. I-DMTDA yi-arhente yokunyanga yendalo yonke ukuze idityaniswe nezinye iidiamine ezingamanzi, umzekelo i-DETDA, ukuhluka kwamazinga okunyanga kunye neempawu zoomatshini ukuhlangabezana neemfuno ezahlukeneyo. Ngoko ke, kukho ukusetyenziswa okubanzi kwe-DMTDA kumavili e-polyurethane, amavili, i-casters, i-roller, i-elastomeric coatings njalo njalo. Ungafumana iimveliso ezigqityiweyo ze-DMTDA kuyo yonke indawo, kubandakanya ulwakhiwo, imigodi, iimoto, i-electronics, ilaphu kunye neendawo zoshicilelo.
Ngokungafani ne-MOCA, i-4,4'-Methylenebis (2-chloroaniline), i-DMTDA ayikrokrelwa ukuba i-carcinogens. I-eco-friendly, ayinayo ityhefu kwaye ikhuselekile ukuba abasebenzi bajongane nayo ngexesha lokulungiswa. Izibonelelo ngokuba kwimo engamanzi, i-DMTDA ayisayi kubangela naluphi na uthuli oluyityhefu, umsi okanye umphunga ngelixa usebenza. Ngoko ke, abasebenzi abayi kuboniswa ingozi ngelixa besebenza ne-DMTDA. Kumaxesha amandulo, abavelisi be-EU polyurethane basebenzisa i-MOCA njengeyona arhente yokunyanga i-TDI-based polyurethane systems ngenxa yexabiso layo eliphantsi, ukusebenza okugqwesileyo kumandla okuqina, ukuqina, ukomelela kunye nokunganyangeki kwe-abrasion. Ukuze kukhuselwe abasebenzi kunye nokusingqongileyo, amazwe amaninzi ngakumbi nangakumbi akwalela ukusetyenziswa kwe-MOCA, ngoko ke, inyanzelisa abavelisi be-polyurethane ukuba bafumane indawo ye-MOCA, i-DMTDA, ekwabizwa ngokuba yi-MOCA yolwelo. I-DMTDA iphelisa ezininzi iingozi zempilo ezinxulumene nokuphatha i-MOCA kwaye ibonelele ngeempawu ezibalaseleyo zomzimba xa kuthelekiswa ne-MOCA-based polyurethanes/polyureas elastomers.
Kukho enye inzuzo ebalulekileyo ye-DMTDA xa ithelekisa ne-MOCA. Ekubeni i-DMTDA ikwimo yolwelo, ivumela ukusebenza kubushushu obuphantsi kune-MOCA. Ngaphandle kwenkqubo yokunyibilika efunekayo kwi-MOCA, unokonga iindleko ezininzi zamandla ngexesha lokuvelisa. Inokwenzeka yokuqinisa ayenzeki kwizikhongozeli zokuxuba okanye kumatshini wokuxuba. Ukongeza, inokusingathwa kumaqondo obushushu asezantsi kune-MOCA kwimeko yolwelo. Ubunzima obulinganayo be-DMTDA yi-107 xa kuthelekiswa ne-MOCA yi-133.5. Oku kuthetha ukuncipha kwe-20% kubunzima be-prepolymer kwi-stoichiometr efanayo
I-DMTDA isetyenziswa njenge-arhente yokunyanga iPU. Inokucothisa umsebenzi weqela elithi "NH2", ngaloo ndlela, ukwandisa ubomi bembiza ngelixa uphosa.
I-DMTDA , ukuba lulwelo kwiqondo lobushushu begumbi kubangela inzuzo ebalulekileyo yokucubungula xa kuthelekiswa ne-MOCA, ukunyibilika kwezinto eziqinileyo akuyomfuneko. Kwakhona, ifom yayo yolwelo ivumela ukucubungula i-prepolymer kwiqondo lokushisa eliphantsi kunelo le-MOCA kwaye ngaphandle kokuqina ngexesha lokuxuba. I-DMTDA inobunzima obulinganayo be-107 xa kuthelekiswa ne-133.5 ye-MOCA. Oku kuthetha ukuba malunga ne-20% ngaphantsi kobunzima obufunekayo kwi-prepolymer enikiweyo kwi-stoichiometry efanayo.
Ukuthelekisa iiPropati zoMzimba we-Prepolymer Unyangelwe nge-DMTDA & MOCA
Iimpawu ezibonakalayo ze-prepolymer, zombini iintlobo ze-ether kunye ne-ester, xa zinyangwa nge-arhente yokunyanga ye-DMTDA, zifaniswa nezo zisekelwe kwi-MOCA. Njengakwinkqubo yokunyanga ye-MOCA, iipropati zomzimba zinovakalelo kwi-ration (stoichiometry) yonyango kwi-prepolymer. I-DMTDA yonyamezelo lomboniso wonyango kwiiyantlukwano ze-stoichiomety ezifanayo nezo ze-MOCA. I-Low stoichiomety (80 ~ 90%) ngokubanzi ithande ukwandisa ukunyanzeliswa kwesethi yoxinzelelo, ngelixa i-stoichiomety ephezulu (100-105%) ithande ukwandisa amandla okukrazula kunye nobomi obuguquguqukayo. Iziphumo ezilungileyo kakhulu kwizicelo ezininzi zifumaneka malunga ne-95% ye-stoichiometry. Ngelixa iimeko zonyango (ubushushu kunye namaxesha) ziyafana nezo zisetyenziswa nge-MOCA, unyango lwe-DMTDA lufuna ingqwalasela ethe kratya kwiimeko zokunyanga ukuze kufumaneke iipropati zomzimba eziphezulu, ngakumbi kwisethi yoxinzelelo kunye neempawu eziguqukayo.
I-DMTDA isetyenziswa ngokubanzi kwiinkqubo zokugquma kwiinkalo zoyilo, iimoto, zaselwandle kunye nezoshishino. I-DMTDA-based polyurethanes coating inokusebenza okuphezulu, njengokuqina kunye nokuqina, amandla aphezulu, ukungangeni kwamanzi, ukumelana nemozulu, ukuxhathisa kwe-abrasion, ukukrazula kunye nokumelana nomhlwa. I-polyurethanes esekwe kwi-DMTDA ingasetyenziswa ngeendlela ezahlukeneyo zokugquma kwi-substrates, oko kukuthi, isinyithi, iplanga, ikhonkrithi, i-masonry kunye nemigangatho yeplastiki.
I-DMTDA inokusetyenziswa njenge-epoxy resin ephilisa i-agent/insulation material kunye ne-PU elastomers, ezifana ne-polyurethane kunye ne-polyurea esetyenziselwa yonke into ukusuka kwi-coatings ephezulu ehlala ixesha elide ukuya kwi-flexible foam seals, kunye namavili kunye namatayara. Ukongeza, i-DMTDA inokufaka isicelo kwiimoto, isakhiwo, imigodi, i-textile, i-roller yokushicilela, amavili etroli, izinto zokuncamathelisa kunye namashishini ombane.
