O-phenylphenol (OPP) waa nooc cusub oo muhiim ah oo ah badeecooyin kiimiko oo fiican iyo dhexdhexaadiyayaal dabiici ah. Waxaa si weyn loogu isticmaalaa beeraha nadiifinta, ka hortagga daxalka, daabacaadda iyo rinjiyeynta kaaliyaha, surfactants, xasiliyeyaasha iyo kuwa dab-damiya ee balaastikada cusub, resins iyo walxaha polymer-ka.
O-phenylphenol waxaa inta badan loo isticmaalaa diyaarinta resin-ka o-phenylphenol formaldehyde, iyo diyaarinta varnish leh biyo iyo xasillooni alkali oo aad u fiican. Varnish-kani wuxuu leeyahay adkeysi xooggan iyo iska caabin cimilo, gaar ahaan ku habboon cimilada qoyan iyo qabow iyo maraakiibta badda.
Opp waa daawo wanaagsan oo ilaalisa miraha iyo khudaarta, waxaa sidoo kale loo isticmaali karaa in lagu daaweeyo liinta, cananaaska, qaraha, isteroberiga, ferskenka, yaanyada, qajaarka, waxay yareyn kartaa qudhunka ilaa ugu yaraan. Boqortooyada Midowday (UK), Mareykanka iyo Kanada waxaa loo oggol yahay inay isticmaalaan noocyo badan oo miro ah, oo ay ku jiraan tufaax, isteroberi, cananaaska, iwm.
Nooc ka mid ah chlorine-ka oo laga soo saaray o-phenylphenol, 2-chloro-4-phenylphenol, oo loo isticmaalo sidii sunta cayayaanka lagu dilo iyo jeermis dile, iyo sidoo kale sunta cayayaanka lagu dilo si loo xakameeyo cudurrada geedaha midhaha. O-phenylphenol waxaa lagu daray sulfonphenol waxaana lagu daray formaldehyde si loo sameeyo firdhiye sunta cayayaanka dila.
Diyaarinta 2-chloro-4-phenylphenol ee OPP waxaa loo isticmaali karaa sidii sunta cayayaanka iyo jeermiska disha, OPP waxaa loo isticmaali karaa in lagu soo saaro emulsifier aan ionic ahayn iyo midabyo macmal ah, o-phenylphenol iyo milixda sodium-ka ee biyaha ku milma ayaa sidoo kale loo isticmaali karaa sidii side rinji ah oo loogu talagalay faybarka polyester-ka, faybarka triacetic acid, iwm.
(1) Samaynta polyester-ka dab-celiya
Dop0 waxaa loo isticmaalay sidii walxo cayriin ah si loogu falceliyo aashitada itaconic si loo sameeyo mid dhexdhexaad ah, odop-bda, kaas oo qayb ahaan beddeli kara ethylene glycol si loo helo fosfooraska cusub ee ka kooban polyester-ka dab-damiya.
(2) Isku-darka resin epoxy resin ololka celiya
Resin-ka Epoxy waxaa si weyn loogu isticmaalaa dhejisyada, qalabka elektaroonigga ah, hawada sare, dahaarka iyo agabka isku-dhafka ah ee horumarsan sababtoo ah isku-dhejinta iyo sifooyinka dahaarka korontada ee aadka u fiican. Sannadkii 2004, isticmaalka resin-ka epoxy ee adduunka wuxuu gaaray in ka badan 200000 tan / sannadkii.
(3) Hagaajinta milmida dabiiciga ah ee polymers-ka
(4) Sida dhexdhexaad ah oo ku jira isku-darka antioxidant-ka
(5) Xasiliyayaal loogu talagalay walxaha polymer-ka ee macmal ah
(6) Waalidka iftiinka sameeya
