O-phenylphenol (OPP) ke mofuta o mocha oa bohlokoa oa lihlahisoa tse ntle tsa lik'hemik'hale le lintho tse kenellang tsa tlhaho. E sebelisoa haholo masimong a ho bolaea likokoana-hloko, ho thibela ho bola, ho hatisa le ho daea, li-surfactant, li-stabilizer le li-retant tsa malakabe tsa polasetiki e ncha, li-resin le thepa ea polymer.
O-phenylphenol e sebediswa haholoholo ho lokisa resin ya o-phenylphenol formaldehyde, le ho lokisa varnish ka botsitso bo botle ba metsi le alkali. Varnish ena e na le botsitso bo matla le ho hanela maemo a lehodimo, haholoholo e loketse maemo a lehodimo a metsi le a batang le dikepe tsa lewatle.
Opp ke sesebelisoa se setle sa ho boloka limela, se ka sebelisoa bakeng sa thibelo ea hlobo ea litholoana le meroho, se ka boela sa sebelisoa ho phekola lemon, phaenapole, mahapu, pere, perekisi, tamati, likomkomere, se ka fokotsa ho bola ho isa bonyenyaneng. United Kingdom, United States le Canada li lumelloa ho sebelisa mefuta e mengata ea litholoana, ho kenyeletsoa liapole, lipere, liphaenapole, jj.
Sehlahisoa se nang le chlorine sa o-phenylphenol, 2-chloro-4-phenylphenol, se sebediswang e le sebolaya-dikokwana-hloko le sebolaya-dikokwana-hloko, le e le sebolaya-dikokwana-hloko bakeng sa taolo ya mafu a difate tsa ditholwana. O-phenylphenol e ile ya kopanngwa le formaldehyde ho etsa sebolaya-dikokwana-hloko.
Ho lokisoa ha 2-chloro-4-phenylphenol ho tsoa ho OPP ho ka sebelisoa e le sebolaya-dikokwana-hloko le sebolaya-dikokwana-hloko, OPP e ka sebelisoa ho hlahisa emulsifier e seng ea ionic le lidae tsa maiketsetso, o-phenylphenol le letsoai la eona la sodium le qhibilihang metsing le tsona li ka sebelisoa e le sejari sa dae bakeng sa faeba ea polyester, faeba ea asiti ea triacetic, jj.
(1) Ho kopanngoa ha polyester e thibelang malakabe
Dop0 e sebelisitsoe e le thepa e tala ho arabela le itaconic acid ho theha karolo e bohareng, odop-bda, e ka nkang sebaka sa ethylene glycol ho fumana phosphorus e ncha e nang le polyester e thibelang malakabe.
(2) Ho kopanngoa ha resin ea epoxy e thibelang malakabe
Resin ea epoxy e sebelisoa haholo ho likhomaretsi, lisebelisoa tsa elektroniki, lifofane, liphahlo le lisebelisoa tse tsoetseng pele tse kopaneng ka lebaka la ho khomarela ha eona hantle le thepa ea ho thibela motlakase. Ka 2004, tšebeliso ea resin ea epoxy lefatšeng e fihlile ho lithane tse fetang 200000 / selemo.
(3) Ho ntlafatsa ho qhibiliha ha li-polymer ka tlhaho
(4) Jwalo ka karolo e bohareng ya ho kopanngwa ha antioxidant
(5) Li-stabilizer bakeng sa thepa ea polymer ea maiketsetso
(6) Motsoali oa khanya ea maiketsetso
