Resin ea China (e hlalosoang ka ho pharaletseng, motsoako ofe kapa ofe oa polymer o ka sebelisoang e le lisebelisoa tse tala bakeng sa lihlahisoa tsa polasetiki o bitsoa resin) indasteri e ntse e tsoela pele ka potlako.Sehlahisoa se tsoela pele ho hola, 'me leano la naha la indasteri le khothaletsa indasteri ea resin ho nts'etsapele ka lehlakoreng la lihlahisoa tsa theknoloji e phahameng.Mefuta e fapaneng ea resin ea Chaena e batla e phethahetse, empa ha e bapisoa le balekane ba tsoetseng pele ba tsoang linaheng tse ling, ho ntse ho e-na le lekhalo le itseng tekanyong ea tlhahiso, taolo ea ts'ebetso le lihlahisoa tse ling tse nang le litlhoko tse khethehileng tsa ts'ebetso.Ka hona, lilemong tse 'maloa tse latelang, ke feela lipatlisiso le nts'etsopele ea lihlahisoa tse phahameng tsa ts'ebetso, ho ntlafatsa botsitso ba boleng ba sehlahisoa, ke taba e potlakileng ea ntlafatso ea resin, hape ke ea bohlokoa.

Light stabilizer ke mofuta oa sesebelisoa se thusang se ka thibelang kapa sa lieha ho senyeha ha resin.Ho pholletsa le boemo ba nts'etsopele le lipatlisiso lapeng le kantle ho naha, nts'etsopele le lipatlisiso tsa li-stabilizers tsa leseli li bonts'a mekhoa le litšoaneleho tse ncha, ho batla ts'ireletso e sebetsang, ts'ireletso ea tikoloho, moruo le ho kopana le maemo a thata a ts'ebetso le ts'ebeliso ea mefuta e mecha ea li-stabilizers tse ncha, sebopeho se secha. esale e le sepheo sa nts'etsopele ea indasteri le lipatlisiso.Haholo-holo, ke tataiso ea bohlokoa ea nts'etsopele ea li-stabilizers tsa leseli ho kopanya lihlopha tse fapaneng tse sebetsang ka molek'hule e le 'ngoe ho etsa hore molek'hule e be le reactivity e mengata le ho ntlafatsa katleho ea eona.Ka ho hlahisa bond ea lik'hemik'hale tsa "reactive monomer" ka ketane ea lekala ea resin kapa ketane e kholo, "reactive light stabilizer" e ka bapala litšobotsi tsa matla a phahameng le ho hanyetsa solvent le ho hanyetsa khanya ea resin, e nang le tebello e matla ea kopo.Keketso ea "reactive light stabilizer" ho resin e ke ke ea ama sebopeho sa limolek'hule tsa resin ka ho teba, empa e ka ntlafatsa likarolo tse ling tsa bofokoli, ebe e ntlafatsa ts'ebetso ea ts'ebetso le ts'ebetso ea ts'ebeliso ea resin, e ntlafatsa boleng ba ts'ebeliso le ts'ebeletso. bophelo ba resin.

Reactive light stabilizer e bolela ho kenyelletsoa ha lihlopha tse sebetsang ka har'a sebopeho sa limolek'hule tsa amine e koetsoeng, e le hore e tlameletsoe kapa e kenngoe mokokotlong oa polymer nakong ea ts'ebetso ea lihlahisoa tsa polymer ho etsa polymer e sa feleng e nang le lihlopha tse sebetsang tsa amine tse koetsoeng.Leseli lena la stabilizer le ka qoba ho falla kapa ho fetoha ha 'mele ho bakoang ke tahlehelo ea khanya ea leseli, ho ntlafatsa le ho ntlafatsa ho hasana ha li-amine light stabilizer tse koetsoeng ka har'a polymer le phello ea ho tsitsisa ha leseli, haholo-holo ka mor'a hore lihlahisoa tsa lihlahisoa tsa polymer li tsosolosoe hape li hlahisoe bocha. , sehlopha sa ho tsitsisa leseli se ntse se ka bapala phello e ntle ea ho tsitsisa leseli.Ho tlamahanngoa ka ho sa feleng ha molek'hule ea amine e koetsoeng mokokotlong oa polymer ke lihlopha tse sebetsang hantle ke mokhoa o sebetsang oa ho rarolla bothata ba ho etsa lifoto tse sa feleng tsa lihlahisoa tsa polasetiki.Lik'hamphani tse tsoang linaheng tse ling tse kenyeletsang Japane Showa Denko, Adico, joalo-joalo, li hlahisitse methacrylate e le sehlopha se sebetsang sa sesebelisoa sa ho tsitsisa leseli, se nang le phello e ntle ea ho tsitsisa leseli.Empa sehlopha sa methacrylate ha se tsitsitse, ha ho kenyelletsoa tlhokahalo ea ho eketsa inhibitor ea polymerization ho qoba ketsahalo ea ho iketsetsa polymerization, kahoo ho ke ke ha qojoa ho eketsa bothata ba ho phekola ka mor'a phekolo.Ho feta moo, methacrylate ke ntho e sa tsitsang e nang le chefo e itekanetseng, e kotsi ho basebetsi.

The reaction light stabilizer e na le melemo e ka tlase:
