Anhydride ea phthalicke motsoako oa bohlokoa oa lik'hemik'hale o bapalang karolo e kholo indastering ea tlhahiso. Lintho tsa eona tse feto-fetohang li etsa hore e be motsoako oa bohlokoa tlhahisong ea lihlahisoa tse fapa-fapaneng, ho tloha ho li-plastiki le li-resin ho ea ho lidae le meriana. Ka poso ena ea blog, re tla hlahloba ts'ebeliso le bohlokoa ba phthalic anhydride indastering ea lik'hemik'hale.
E 'ngoe ea litšebeliso tsa mantlha tsa anhydride ea phthalic ke tlhahiso ea li-plasticizers tsa phthalate, tse sebelisetsoang ho etsa PVC (polyvinyl chloride) e tenyetsehang le e tšoarellang. Li-plasticizer tsena li bohlokoa bakeng sa ts'ebeliso e fapaneng, ho kenyelletsa mehala le likhoele, fatše le lisebelisoa tsa bongaka. Ntle le phthalic anhydride, tlhahiso ea lisebelisoa tsena tsa bohlokoa e ka sitisoa haholo.
Phthalic anhydride hape ke motsoako oa bohlokoa tlhahisong ea li-resine tsa polyester tse sa sebetseng, tse sebelisoang haholo ha ho etsoa lipolasetiki tse matlafalitsoeng ka fiberglass. Li-resin tsena li sebelisoa indastering ea likoloi, ea kaho le ea likepe, har'a tse ling, ka lebaka la matla a tsona a matle, ho tšoarella ha tsona, le ho hanyetsa ho bola. Ntle le phthalic anhydride, tlhahiso ea li-resin tsena tsa bohlokoa e ne e ke ke ea khoneha.
Ntle le lipolasetiki le li-resin, phthalic anhydride e boetse e sebelisoa ha ho etsoa dae le li-pigments. E sebetsana le mefuta e fapaneng ea lik'hemik'hale ho etsa metsoako ea mebala e sebelisoang indastering ea masela, pampiri le polasetiki. Lidae tsena le li-pigments li bohlokoa bakeng sa tlhahiso ea mefuta e mengata ea lihlahisoa, ho tloha ho liaparo le liphutheloana ho ea ho thepa e hatisitsoeng le thepa ea bareki.
Ho feta moo, phthalic anhydride ke motsoako oa bohlokoa tlhahisong ea meriana e itseng le lik'hemik'hale tsa temo. E sebelisoa ha ho etsoa litlhare tse fapaneng le chefo e bolaeang likokoanyana, e kenyang letsoho ntlafatsong ea tlhokomelo ea bophelo le temo. Ntle le phthalic anhydride, tlhahiso ea lik'hemik'hale tsena tsa bohlokoa e ka ameha haholo.
Leha e na le ts'ebeliso e fapaneng, ho bohlokoa ho hlokomela hore phthalic anhydride e hlahisitse matšoenyeho mabapi le litlamorao tse ka bang teng tsa bophelo bo botle le tikoloho. Ho bohlokoa hore bahlahisi ba sebetse le ho sebelisa phthalic anhydride ka boikarabelo ho fokotsa likotsi tse ka bang teng. Ho feta moo, bafuputsi le bo-ramahlale ba lula ba hlahloba metsoako e meng le mekhoa ea tlhahiso ho rarolla mathata ana le ho theha tharollo e tšoarellang.
Qetellong, phthalic anhydride ke motsoako oa bohlokoa oa lik'hemik'hale o bohlokoa haholo indastering ea tlhahiso. Tšebeliso ea eona e feto-fetohang ha ho etsoa lipolasetiki, li-resin, dae, meriana le lik'hemik'hale tsa temo li e etsa motsoako oa bohlokoa lihlahisoa tse fapaneng tseo re li sebelisang bophelong ba rona ba letsatsi le letsatsi. Ha indasteri e ntse e tsoela pele ho fetoha, ho bohlokoa ho beha pele ts'ebeliso e nang le boikarabelo le e tsitsitseng ea phthalic anhydride ho fokotsa litlamorao tse ka bang teng bophelong ba batho le tikolohong.
