Ingcaciso yeMveliso

I-DimethylthioToluene Diamie / DMTDA, inombolo ye-CAS. 106264-79-3, yindlela yokwelapha i-diamines kwiinkqubo ze-TDI kunye ne-MDI. Ukuba lulwelo oluqinileyo kubushushu begumbi kubangela iingenelo ezibalulekileyo zokucubungula, oko kukuthi, kulula ukudlulisa, ukulungele ukusetyenziswa ngaphandle kokunyibilikisa izinto eziqinileyo njengoko i-MOCA isenza. I-DMTDA yiarhente efanelekileyo yokunyanga esetyenziselwa ukwenza i-polyurethane/polyurea elastomers eqinileyo neguquguqukayo.

I-DMTDA inokuba yiarhente yokuphilisa kunye nesandisi setyathanga kwi-diisocyanate pre-polymers, ingakumbi kwinkqubo ye-polyurea enika iipropati ezilungileyo zoomatshini kunye ne-dynamic. I-DMTDA yiarhente yokuphilisa edibeneyo nezinye ii-diamines zolwelo, umzekelo i-DETDA, ukutshintsha amazinga okuphilisa kunye neepropati zoomatshini ukuhlangabezana neemfuno ezahlukeneyo. Ke ngoko, kukho ukusetyenziswa okubanzi kwe-DMTDA kumavili e-polyurethane, amatayara, ii-casters, ii-rollers, ii-elastomeric coatings njalo njalo. Ungafumana iimveliso ezigqityiweyo ze-DMTDA kuyo yonke indawo, kubandakanya ulwakhiwo, ukumbiwa kwemigodi, iimoto, ii-elektroniki, amalaphu kunye neendawo zokuprinta.

Ngokungafaniyo ne-MOCA, i-4,4'-Methylenebis (2-chloroaniline), i-DMTDA ayikrokrelwanga ukuba yi-carcinogens. Inobuhlobo nokusingqongileyo, ayinabungozi kwaye ikhuselekile kubasebenzi ukuba bayiphathe ngexesha lokucubungula. Iingenelo zokuba kwimo yolwelo, i-DMTDA ayizukubangela naluphi na uthuli olunobuthi, umsi okanye umphunga ngelixa isebenza. Ke ngoko, abasebenzi abayi kuvezwa kwingozi ngelixa besebenzisa i-DMTDA. Kumaxesha angaphambili, abavelisi be-polyurethane be-EU basebenzisa i-MOCA njengesixhobo esiphambili sokulungisa iinkqubo ze-polyurethane ezisekwe kwi-TDI ngenxa yexabiso layo eliphantsi, ukusebenza kakuhle kumandla okuxinana, ukuqina, ukuqina kunye nokumelana nokukrala. Ukuze kukhuselwe abasebenzi kunye nokusingqongileyo, amazwe amaninzi ayekwalela ukusetyenziswa kwe-MOCA, ngoko ke, inyanzela abavelisi be-polyurethane ukuba bafumane indawo ye-MOCA, i-DMTDA, ekwabizwa ngokuba yi-MOCA engamanzi. I-DMTDA isusa uninzi lweengozi zempilo ezinxulumene nokuphatha i-MOCA kwaye ibonelela ngeempawu zomzimba ezintle xa kuthelekiswa ne-polyurethanes/polyureas elastomers ezisekwe kwi-MOCA.

Kukho enye inzuzo ebalulekileyo ye-DMTDA xa ithelekiswa ne-MOCA. Ekubeni i-DMTDA ikwimo yolwelo, ivumela ukusebenza kubushushu obuphantsi kune-MOCA. Ngaphandle kwenkqubo yokunyibilikisa into efunekayo kwi-MOCA, unokonga iindleko ezininzi zamandla ngexesha lokwenziwa. Amathuba okuqina awenzeki kwizikhongozeli zokuxuba okanye kwiimatshini zokuxuba. Ukongeza, inokuphathwa kubushushu obuphantsi kune-MOCA ngenxa yemeko yayo yolwelo. Ubunzima obulinganayo be-DMTDA yi-107 xa kuthelekiswa ne-MOCA yi-133.5. Oku kuthetha ukwehla kwe-20% kubunzima be-prepolymer kwi-stoichiometr efanayo.

Ukusebenza kunye neempawu

I-DMTDA isetyenziswa njenge-PU ephilisayo. Ingacothisa umsebenzi weqela le-"NH2", ngaloo ndlela, yandisa ubomi bembiza ngexesha lokuphosa.

I-DMTDA, ekubeni ilulwelo kubushushu begumbi, ibangela inzuzo enkulu yokucubungula xa kuthelekiswa ne-MOCA, ukunyibilika kwezinto eziqinileyo akufuneki. Kwakhona, imo yayo yolwelo ivumela ukucutshungulwa kwe-prepolymer kubushushu obuphantsi kune-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 ngobunzima kuyafuneka kwi-prepolymer ethile kwi-stoichiometry efanayo.

Ukuthelekiswa kweempawu ezibonakalayo zePrepolymer ePhiliswe ngeDMTDA kunye neMOCA

Iipropati zomzimba ze-prepolymer, zombini iintlobo ze-ether kunye ne-ester, xa zinyangwa nge-DMTDA curing agent, ziyafana nezo zisekelwe kwi-MOCA. Njengakwinkqubo yokwelapha ye-MOCA, iipropati zomzimba zinovelwano kwi-ration (stoichiometry) yonyango kwi-prepolymer. Ukunyamezelana kokubonakaliswa konyango lwe-DMTDA kwiinguqu ze-stoichiomety kufana nokwe-MOCA. I-stoichiomety ephantsi (80~90%) idla ngokwandisa ukumelana kweseti yoxinzelelo, ngelixa i-stoichiomety ephezulu (100-105%) ithambekele ekunyuseni amandla okukrazula kunye nobomi bokuguquguquka. Iziphumo ezilungileyo zokusetyenziswa uninzi zifumaneka kwi-stoichiometry emalunga ne-95%. Ngelixa iimeko zonyango (ubushushu kunye namaxesha) zifana nezo zisetyenziswa kwi-MOCA, i-DMTDA curing ifuna ingqalelo esondeleyo kwiimeko zonyango emva konyango ukuze ifumane iipropati eziphezulu zomzimba, ngakumbi kwiseti yoxinzelelo kunye neepropati eziguqukayo.

Isicelo

I-DMTDA isetyenziswa kakhulu kwiinkqubo zokugquma kwiindawo zokulungisa izakhiwo, iimoto, ezolwandle kunye nezoshishino. I-DMTDA-based polyurethanes coating isebenza kakuhle, njengokuqina nokuthamba, amandla aphezulu, ukungangeni manzi, ukumelana nemozulu, ukumelana nokukrweleka, ukukrweleka kunye nokumelana nokugqwala. I-DMTDA-based polyurethanes ingasetyenziswa ngeendlela ezahlukeneyo zokugquma kwi-substrates, oko kukuthi, iintsimbi, iinkuni, ikhonkrithi, izakhiwo zamatye kunye neplastiki.

I-DMTDA ingasetyenziswa njenge-epoxy resin curing agent/insulation material kunye ne-PU elastomers, ezifana ne-polyurethane kunye ne-polyurea ezisetyenziselwa yonke into ukusuka kwiingubo ezihlala ixesha elide ukuya kwii-flexible foam seals, amavili kunye namatayara. Ukongeza, i-DMTDA ingafakwa kwiimoto, izakhiwo, imigodi, amalaphu, ii-printing rollers, amavili etroli, izincamathelisi kunye namashishini e-elektroniki.
