Enye into ebalulekileyo enjalo yiDimethyl Thio Toluene Diamine (DMTDA). Ukuba ujonge ukwenza nzulu ulwazi lwakho malunga neepropathi zeDimethyl thio toluene diamine, esi sikhokelo siyakuhamba ngeempawu eziphambili ezenza le khompawundi ixabiseke kakhulu kumashishini amaninzi.

Yintoni iDimethyl Thio Toluene Diamine?

Phambi kokuntywila kwiipropathi zayo, kubalulekile ukuba uqale uqonde ukuba yintoni kanye kanye iDimethyl Thio Toluene Diamine. Ngokuqhelekileyo ishunqulelwe njenge-DMTDA, le khompawundi yemichiza isetyenziswa ngokubanzi njenge-arhente yokunyanga ii-elastomers ze-polyurethane kunye neengubo. Enkosi kubume bayo obukhethekileyo bemolekyuli, i-DMTDA ibonelela ngokudityaniswa kokusebenza kwakhona, ukuguquguquka, kunye nokumelana nokuba zimbalwa ezinye izinto ezinokuhambelana.

Ukuphonononga iipropathi zeDimethyl thio toluene diamine akuncedi kuphela ekukhetheni izinto ezifanelekileyo kwiiprojekthi ezithile kodwa nokuphucula ukusebenza kwemveliso ngokubanzi kunye nokuqina.

IiPropati zoBume be-DMTDA: Yintoni ekufuneka uyazi

Enye yeempawu ezibalaseleyo ze-DMTDA lulungelelwano olugqwesileyo phakathi kwe-viscosity kunye nokusebenza kwakhona. Ibonakala njengolwelo olucacileyo, olutyheli kancinci kwiqondo lobushushu begumbi, iyenza kube lula ukuyiphatha kunye nokudityaniswa kwimixube.

Ukongeza, i-DMTDA ibonelela ngendawo yokukhenkceza ephantsi kunye nokusebenza okuzinzileyo kuluhlu olubanzi lwamaqondo obushushu. Ezi zakhiwo zeDimethyl thio toluene diamine zenza ukuba zilungele iindawo apho ukusebenza okuhambelanayo phantsi kweemeko ezahlukeneyo kubalulekile.

Ngaphezu koko, uxinzelelo lwalo lomphunga olusezantsi lunegalelo ekuphatheni okukhuselekileyo kunye nokuncipha kokuguquguquka xa kuthelekiswa nezinye iiarhente zokunyanga ezisekwe kwi-amine.

Iipropati zeMichiza: Kutheni i-DMTDA iGqwesa

Ukusuka kwimbono yeekhemikhali, i-DMTDA ixabiswa ngenxa yeereyithi zayo zokusabela ezilawulwayo. Ngokungafaniyo nee-amines ezinobundlongondlongo, i-DMTDA ivumela ixesha elide lokusebenza ngaphandle kokuncama amandla okugqibela. Oku kunika abavelisi ukuguquguquka okukhulu ngexesha lokucubungula kunye nokudibanisa.

Enye ipropati ephawulekayo yeekhemikhali kukuchasana kwayo okuphezulu kwi-hydrolysis kunye ne-oxidation. Ezi zakhiwo ze-Dimethyl thio toluene diamine ziqinisekisa ukuba izinto ezinyangwa nge-DMTDA zigcina ingqibelelo yazo yesakhiwo nakwiindawo ezinomngeni ezifana nokufuma okuphezulu, ukuvezwa kwamanzi, okanye i-atmospheres yekhemikhali.

Izinto eziluncedo ezingundoqo ezifumaneka kwiiPropati zayo

Ukuqonda iipropathi zeDimethyl thio toluene diamine zibonisa iingenelo ezininzi ezisebenzayo:

Ubomi bembiza obandisiweyo ngexesha lokucubungula ngaphandle kokubeka esichengeni ukusebenza konyango.

Ukuphuculwa kokuqina kunye nokuguquguquka kwiimveliso zokugqibela.

Ukumelana okugqwesileyo kokuthotywa kokusingqongileyo, kubandakanya ukufuma kunye nokuvezwa kweekhemikhali.

Ukomelezwa kokwenziwa koomatshini ukwenzela ukuthembeka kwexesha elide.

Ezi zibonelelo zichaza ukuba kutheni i-DMTDA isetyenziswa kakhulu kumashishini afana neemoto, ulwakhiwo, i-aerospace, kunye nokuveliswa koomatshini abakhulu.

Izicelo Ezisebenzisa IiPropati eziZodwa zeDMTDA

Ngenxa yeempawu zayo ezinamandla, i-DMTDA ifumana indlela yayo kwizicelo ezininzi apho ukusebenza phantsi koxinzelelo kubalulekile. Idla ngokusetyenziswa ekuvelisweni kwee-elastomers ezikwaziyo ukumelana nokuqina okuphezulu, ii-coatings ezifuna ukuxhathisa uhlaselo lwekhemikhali, kunye nezinto ezincamathelayo ekufuneka zimelane nemithwalo eguqukayo ixesha elide.

Xa ujonga ngokusondeleyo kwiipropathi ze-Dimethyl thio toluene diamine, kuyacaca ukuba le nto idlala indima ebalulekileyo ekunikezeni iimveliso ezinamandla, ezihlala ziqinile, kwaye zithembeke ngakumbi.

Ukuqukumbela

Kumashishini akhuphisanayo namhlanje, ukukhetha iikhompawundi zeekhemikhali ezifanelekileyo kunokuchaphazela kakhulu ukusebenza kwemveliso kunye nokuphila ixesha elide. Ngeseti yayo ekhethekileyo yeenzuzo zomzimba kunye neekhemikhali, ukuqonda iipropathi zeDimethyl thio toluene diamine zibalulekile kuye nabani na ojonge ukuphucula izixhobo kunye neenkqubo zabo.
