Ha ho tluoa tabeng ea ho theha lisebelisoa tsa epoxy tse sebetsang hantle, khetho ea moemeli oa phekolo e phetha karolo ea bohlokoa. Har'a mekhoa e sa tšoaneng e fumanehang, DMTDA e hlahile e le moemeli ea ka tšeptjoang le ea sebetsang hantle oa phekolo ea tsebahalang ka ho ntlafatsa ts'ebetso ea kakaretso ea li-epoxy resin. Hore na o etsa litlolo tsa indasteri, likhomaretsi, kapa lisebelisoa tse kopaneng, ho utloisisa melemo eaDMTDAka li-resin tsa epoxy li ka u fa monyetla oa tlholisano.

Ho notlolla ho Fetoha ho Fetisisa le ho Thatafala

E 'ngoe ea liqholotso tsa bohlokoa ho epoxy formulations ke ho leka-lekanya ho tiea le ho tiea. DMTDA (Dimethylthiotoluenediamine) e thusa ho koala lekhalo lena ka ho hlahisa likarolo tse feto-fetohang ho marang-rang a polymer. Ho feto-fetoha ha maemo ho lebisa ntlafatsong ea ho hanyetsa le ho fokotsa brittleness, ho etsa hore e be e loketseng bakeng sa lisebelisoa tse hlokang matla le nako e telele.

Ha e sebelisoa ka nepo, DMTDA ka li-resin tsa epoxy e kenya letsoho ho ntlafatsa thepa ea elongation, ho netefatsa hore sehlahisoa sa ho qetela se ka mamella khatello ea mochine ntle le ho senya kapa ho senya.

Ntlafatso ea ho hanyetsa Thermal le Chemical Resistance

Lisebelisoa tsa sejoale-joale tsa epoxy hangata li kenyelletsa ho pepesehela tikoloho e thata-ebang ke mocheso, mongobo kapa lik'hemik'hale. DMTDA e nkoa e le ea bohlokoa ka lebaka la bokhoni ba eona ba ho ntlafatsa botsitso ba mocheso le khanyetso ea lik'hemik'hale mekhoeng ea epoxy. Sena se bolela hore lisebelisoa tse phekotsoeng ka DMTDA li boloka thepa ea tsona ho feta mefuta e mengata ea mocheso le maemo, ho netefatsa ho tšepahala le maemong a mabifi a indasteri.

Ka ho kenyelletsa DMTDA ho li-epoxy resin, bahlahisi ba ka hlahisa liforomo tse bolokang botšepehi tlas'a libaesekele tse futhumatsang le ho pepesehela lisebelisoa tse senyang, tse etsang hore li tšoanelehe bakeng sa ho sebelisoa sebakeng sa lifofane, lisebelisoa tsa elektroniki le tsa likoloi.

Bophelo bo Bolelele ba Pitsa, Pheko e potlakileng-Motsoako o Hlōlang

Ho feto-fetoha ha maemo ho bohlokoa lits'ebetsong tsa epoxy, 'me sena ke sebaka se seng moo DMTDA e khanyang teng. E fana ka bophelo bo bolelele ba pitsa mocheso oa kamore, e fa basebelisi nako e eketsehileng ea ho kopanya le ho sebelisa sebopeho. Leha ho le joalo, hang ha mocheso o sebelisoa, mokhoa oa ho phekola o potlakisa haholo, o fokotsa nako ea ho theoha le ho eketsa tlhahiso.

Melemo ena e 'meli e etsa hore DMTDA ka li-epoxy resin e khahle haholo tlhahisong e kholo ea indasteri moo ho sebetsang hantle le ts'ebetso e tsitsitseng e leng bohlokoa.

E lumellana le Litsamaiso tse fapaneng tsa Epoxy

Ha se lisebelisoa tsohle tsa ho phekola tse lumellanang hohle, empa DMTDA e tsebahala ka ho lumellana ha eona hantle le mefuta e mengata ea li-epoxy resin, ho kenyelletsa le mefuta ea bisphenol-A le bisphenol-F. Ts'ebetso ena e fapaneng e thusa baetsi ba lihlahisoa ho sebelisa DMTDA lits'ebetsong tse fapaneng ntle le ho lokisa kapa ho lokisa, ho boloka nako le litšenyehelo.

Hore na o ntse o etsa sebopeho se secha kapa o fetola se seng se ntse se le teng, ho kopanya DMTDA ho li-epoxy resin ho ka u thusa ho fihlela liphetho tse tsitsitseng ka liteko tse fokolang le liphoso.

Mokhoa o Sireletsehileng ka ho Fetisisa oa Diamine tse Monko

Li-diamine tsa setso tse nkhang hamonate hangata li tla le mathata a bophelo bo botle le ho sebetsana le mathata. DMTDA e fana ka mokhoa o mong o sireletsehileng, o nang le chefo e tlase le thepa ea ho sebetsana hantle, e leng bohlokoa haholo libakeng tsa mosebetsi tse tsepamisitsoeng holim'a polokeho le ho latela melao.

Ka ho khetha DMTDA ka li-resin tsa epoxy, bahlahisi ha ba ntlafatse ts'ebetso ea sehlahisoa feela empa hape ba kenya letsoho libakeng tse sireletsehileng tsa tlhahiso.

Ha litlhokahalo tsa lisebelisoa tse matla, tse tšoarellang haholoanyane, le tse sebetsang hantle li ntse li eketseha, DMTDA e ipaka e le karolo ea bohlokoahali mekhoeng ea sejoale-joale ea epoxy resin. Ho tloha ho matla a ntlafetseng le ho hanyetsa mocheso ho ea ho ts'ebetso e ntlafetseng le polokeho, melemo ea eona e etsa khetho e bohlale bakeng sa baetsi ba ho nahana pele.

Na u se u itokiselitse ho hlahloba lits'ebetso tse tsoetseng pele tsa epoxy tse lumellanang le litlhoko tsa hau tsa ts'ebetso? Kopana leLehlohonolole ho notlolla bokhoni bo felletseng ba theknoloji ea epoxy e nang le litharollo tsa boleng bo holimo tse etselitsoeng mathata a hosane.
