O-phenylphenol (OPP) ndi mtundu watsopano wofunikira wa mankhwala abwino komanso zinthu zina zachilengedwe. Imagwiritsidwa ntchito kwambiri m'magawo oyeretsera, oletsa dzimbiri, othandizira kusindikiza ndi kupaka utoto, ma surfactants, okhazikika komanso oletsa moto a pulasitiki yatsopano, ma resins ndi zinthu za polima.
O-phenylphenol imagwiritsidwa ntchito kwambiri pokonza utomoni wa o-phenylphenol formaldehyde, komanso pokonza varnish yokhala ndi madzi abwino komanso kukhazikika kwa alkali. Varnish iyi imakhala yolimba kwambiri komanso yolimba, makamaka yoyenera nyengo yamvula ndi yozizira komanso zombo zapamadzi.
Opp ndi mankhwala abwino otetezera, angagwiritsidwe ntchito popewa matenda a mildew a zipatso ndi ndiwo zamasamba, angagwiritsidwenso ntchito pochiza mandimu, chinanazi, vwende, peyala, pichesi, phwetekere, nkhaka, komanso amachepetsa kuwola. United Kingdom, United States ndi Canada amaloledwa kugwiritsa ntchito mitundu yosiyanasiyana ya zipatso, kuphatikizapo maapulo, mapeyala, chinanazi, ndi zina zotero.
Chochokera ku o-phenylphenol, 2-chloro-4-phenylphenol chomwe chili ndi chlorine, chimagwiritsidwa ntchito ngati mankhwala ophera tizilombo komanso opha tizilombo toyambitsa matenda, komanso ngati mankhwala ophera tizilombo toyambitsa matenda polimbana ndi matenda a mitengo ya zipatso. O-phenylphenol inaphatikizidwa ndi sulfonate ndipo inaphatikizidwa ndi formaldehyde kuti ipange dispersant yopangira mankhwala ophera tizilombo.
Kukonzekera kwa 2-chloro-4-phenylphenol kuchokera ku OPP kungagwiritsidwe ntchito ngati mankhwala ophera tizilombo komanso opha tizilombo toyambitsa matenda, OPP ingagwiritsidwe ntchito popanga emulsifier yosakhala ionic ndi utoto wopangidwa, o-phenylphenol ndi mchere wake wa sodium wosungunuka m'madzi zingagwiritsidwenso ntchito ngati chonyamulira utoto wa polyester fiber, triacetic acid fiber, ndi zina zotero,
(1) Kupanga kwa polyester yoletsa moto
Dop0 idagwiritsidwa ntchito ngati zinthu zopangira kuti igwirizane ndi itaconic acid kuti ipange odop-bda yapakatikati, yomwe ingalowe m'malo mwa ethylene glycol kuti ipange phosphorous yatsopano yokhala ndi polyester yoletsa moto.
(2) Kupanga utomoni wa epoxy woletsa moto
Utomoni wa epoxy umagwiritsidwa ntchito kwambiri mu zomatira, zida zamagetsi, ndege, zokutira ndi zipangizo zamakono chifukwa cha kumatira kwake kwabwino komanso mphamvu zake zotetezera magetsi. Mu 2004, kugwiritsidwa ntchito kwa utomoni wa epoxy padziko lonse lapansi kunafika matani opitilira 200000 pachaka.
(3) Kukweza kusungunuka kwa ma polima m'chilengedwe
(4) Monga gawo lapakati pa kapangidwe ka antioxidant
(5) Zokhazikika pa zipangizo zopangidwa ndi polima
(6) Chopanga chowunikira chopangidwa
