Ha ho tluoa tabeng ea lisebelisoa tse sebetsang hantle liindastering le lik'hemik'hale, ho bohlokoa ho utloisisa litšobotsi tsa mantlha tsa metsoako ea hau. Ntho e 'ngoe ea bohlokoa joalo ke Dimethyl Thio Toluene Diamine (DMTDA). Haeba u batla ho tebisa tsebo ea hau mabapi le thepa ea Dimethyl thio toluene diamine, tataiso ena e tla u tsamaisa ka lintlha tsa bohlokoa tse etsang hore komporo ena e be ea bohlokoa haholo liindastering tse ngata.

Ke engDimethyl Thio Toluene Diamine?

Pele u kenella ka har'a thepa ea eona, ho bohlokoa ho qala ho utloisisa hore na Dimethyl Thio Toluene Diamine ke eng. Ka tloaelo e khutsufatsoa e le DMTDA, motsoako ona oa lik'hemik'hale o sebelisoa haholo e le pheko ea li-elastomer tsa polyurethane le liphahlo. Ka lebaka la sebopeho sa eona se ikhethang sa limolek'hule, DMTDA e fana ka motsoako oa ts'ebetso, ho tenyetseha le ho hanyetsa hoo lisebelisoa tse ling tse seng kae li ka bapisang.

Ho hlahloba thepa ea Dimethyl thio toluene diamine ha e thuse feela ho khetha thepa e nepahetseng bakeng sa merero e itseng empa hape e ntlafatsa tshebetso ea sehlahisoa ka kakaretso le ho tšoarella.

Thepa ea 'Mele ea DMTDA: Seo U Lokelang ho se Tseba

E 'ngoe ea likarolo tse hlahelletseng tsa DMTDA ke ho leka-lekana ha eona lipakeng tsa viscosity le reactivity. E bonahala e le mokelikeli o hlakileng, o mosehla hanyenyane mochesong oa kamore, ho etsa hore ho be bonolo ho sebetsana le ho kopana le metsoako.

Ho phaella moo, DMTDA e fana ka sebaka se tlaase sa leqhoa le ts'ebetso e tsitsitseng ho pholletsa le mefuta e mengata ea mocheso. Lintho tsena tsa Dimethyl thio toluene diamine li etsa hore e be sebaka se loketseng bakeng sa tikoloho moo ts'ebetso e tsitsitseng tlas'a maemo a sa tšoaneng e leng bohlokoa.

Ho feta moo, khatello ea eona e batlang e le tlase ea mouoane e kenya letsoho ho ts'oaroe ho bolokehileng le ho fokotsa ho fetoha ha maemo ha ho bapisoa le lisebelisoa tse ling tsa amine.

Lintho tsa Lik'hemik'hale: Hobaneng ha DMTDA e sebetsa hantle

Ho ea ka pono ea lik'hemik'hale, DMTDA e nkoa e le ea bohlokoa ka lebaka la litekanyetso tsa eona tse laoloang. Ho fapana le li-amine tse mabifi, DMTDA e lumella nako e telele ea ho sebetsa ntle le ho tela matla a ho qetela. Sena se fa bahlahisi ho fetoha ha maemo ho feta nakong ea ts'ebetso le kopano.

Ntho e 'ngoe e tsotehang ea lik'hemik'hale ke ho hanyetsa ha eona ho hydrolysis le oxidation. Lintho tsena tsa Dimethyl thio toluene diamine li netefatsa hore lisebelisoa tse phekoloang ka DMTDA li boloka botšepehi ba tsona ba sebopeho esita le libakeng tse thata tse kang mongobo o phahameng, ho pepesehela metsi, kapa boemo ba leholimo ba lik'hemik'hale.

Melemo ea Bohlokoa e Nkiloeng ho Thepa ea Tsona

Ho utloisisa thepa ea Dimethyl thio toluene diamine ho senola melemo e mengata e sebetsang:

Bophelo bo atolositsoeng ba pitsa nakong ea ts'ebetso ntle le ho senya ts'ebetso ea pheko.

Matla a ntlafetseng le ho fetoha ha maemo ho lihlahisoa tsa ho qetela.

Ho hanyetsa ka mokhoa o babatsehang ho senyeha ha tikoloho, ho kenyelletsa le mongobo le ho pepeseha ha lik'hemik'hale.

Melemo ena e hlalosa hore na ke hobane'ng ha DMTDA e sebelisoa haholo liindastering tse kang tsa likoloi, tsa kaho, tsa lifofane le tsa mechine e boima.

Lisebelisoa tse Ikemetseng Lintho tse Ikhethang tsa DMTDA

Ka lebaka la litšobotsi tsa eona tse matla, DMTDA e fumana mokhoa oa ho kena lits'ebetsong tse ngata moo ho sebetsang tlas'a khatello ea kelello ho hlokahalang. Hangata e sebelisoa ha ho etsoa li-elastomers tse matla haholo, tse hlokang ho hanela litlhaselo tsa lik'hemik'hale, le likhomaretsi tse tlamehang ho mamella meroalo e matla ka nako e telele.
