Anhydride ea Trimellitic (CAS: 552-30-7) ke motsoako oa lintho tse phelang o nang le foromo ea C9H4O5C9H4O5. Ke kristale e tšoeu e tiileng e tsejoang ka ts'ebetso ea eona e phahameng le ho tenyetseha ha eona, e leng se etsang hore e be karolo ea bohlokoa ea ts'ebetso ea lik'hemik'hale tse fapaneng.
Litšebeliso tsa Bohlokoa tsaTrimellitic Anhydride (TMA)
1. Lisebelisoa tsa polasetiki
TMA ke thepa ea bohlokoa tlhahisong ea li-plasticizer tsa trimellitate, tse kang Trioctyl Trimellitate (TOTM). Li-plasticizer tsena li sebelisoa haholo ho:
Lihlahisoa tsa PVC: Ho ntlafatsa ho tenyetseha, ho tšoarella, le ho hanyetsa mocheso ka har'a likhoele, fatše le likarolo tsa likoloi.
Litšebeliso tsa Mocheso o Phahameng: Ho fana ka ts'ebetso e phahameng libakeng tseo li-plasticizer tsa setso li hlōlehang ho li sebelisa.
2. Liaparo le Li-resin
TMA e sebelisetsoa ho kopanya polyester le li-resin tsa epoxy tse sebetsang hantle, tse bohlokoa bakeng sa:
Liaparo: Li fana ka ho khomarela ho hoholo, ho hanyetsa lik'hemik'hale, le ho tšoarella ha liaparo tsa indasteri le tse sireletsang.
Liaparo tsa Phofo: Li fana ka phallo le qetello e ntle bakeng sa lisebelisoa, thepa ea ka tlung le likarolo tsa likoloi.
3. Likhomaretsi le Litiiso
Li-resin tse thehiloeng ho TMA li sebelisetsoa ho hlahisa likhomaretsi le li-sealant tse matla haholo, tse fanang ka:
Ho Tsitsisa Thempereichara: Ho mamella mocheso o feteletseng ntle le ho lahleheloa ke ts'ebetso.
Ho Hanela Lik'hemik'hale: Ho netefatsa litlamo tse tšoarellang nako e telele libakeng tse thata.
4. Lipolasitiki tsa Boenjiniere
TMA ke karolo ea bohlokoa tlhahisong ea li-resin tsa polyimide, tse sebelisoang ho:
Lisebelisoa tsa elektroniki: E le thepa ea ho thibela mocheso bakeng sa liboto tsa potoloho le lipotoloho tse hatisitsoeng tse tenyetsehang.
Sefofane: Bakeng sa likarolo tse bobebe, tse hanelang mocheso.
Ke Hobane'ng ha U Lokela ho Khetha Trimellitic Anhydride ea Rona (TMA)?
At Unilong, re motlotlo ka ho fana ka Trimellitic Anhydride e hloekileng haholo e fihlelang maemo a holimo a indasteri. Sena ke se re khethollang:
Boleng bo Ikhethang: Lihlahisoa tsa rona li laoloa ka thata ho netefatsa hore li tsitsitse ebile lia tšepahala.
Litharollo tse Ikhethileng: Re fana ka mekhoa e etselitsoeng uena ho fihlela litlhoko tsa hau tse ikhethileng.
Rea Finyella Lefatše: Ka ketane e matla ea phepelo, re fa bareki lefats'eng ka bophara, re netefatsa hore tšebeletso e etsoa ka nako le ka katleho.
Tšehetso ea Botekgeniki: Sehlopha sa rona sa litsebi se lula se loketse ho u thusa ka tataiso ea botekgeniki le tšehetso ea ts'ebeliso.
