He momo matū hou nui te O-phenylphenol (OPP) o ngā hua matū pai me ngā takawaenga waro. He whānuitia te whakamahinga i roto i ngā mara o te whakahoromata, te ārai-waikura, ngā āwhina tā me te tae, ngā matū horoi, ngā mea whakaū me ngā mea ārai mura o ngā kirihou hou, ngā kapia me ngā rauemi polymer.
Ko te nuinga o te wā ka whakamahia te O-phenylphenol hei hanga i te kapia o-phenylphenol formaldehyde, hei hanga hoki i te wanihi me te pumau pai ki te wai me te kawakore. He pakari te roa o tēnei wanihi, ā, he ātete ki te huarere, he tino pai mō te rangi mākū me te makariri me ngā kaipuke moana.
He pai te Opp hei tiaki i ngā hua rākau, ka taea te whakamahi hei ārai i te harore huarākau me te huawhenua, ka taea hoki te whakamahi hei rongoā mō te rēmana, te paināporo, te merengi, te pea, te pītiti, te tōmato, te kūkamo, ā, ka taea te whakaiti i te pirau ki te iti rawa. E whakaaetia ana te United Kingdom, te United States me Canada ki te whakamahi i te whānuitanga o ngā hua rākau, tae atu ki te aporo, te pea, te paināporo, me ētahi atu.
He matū kua whakapūkaratia ki te chlorine o te o-phenylphenol, 2-chloro-4-phenylphenol, e whakamahia ana hei patu taru me te patu huakita, hei patu harore hoki mō te whakahaere i ngā mate rākau hua. I whakapūkaratia te O-phenylphenol, ā, i whakakōpiritia ki te formaldehyde hei hanga i te waiwhakamarara mō ngā patu taru.
Ka taea te whakamahi i te 2-chloro-4-phenylphenol mai i te OPP hei patu taru me te patu huakita, ka taea te whakamahi i te OPP hei whakaputa i te emulsifier kore-ionic me ngā tae hangai, ka taea hoki te whakamahi i te o-phenylphenol me tōna tote konutai wairewa-wai hei kawe tae mō te muka polyester, te muka waikawa triacetic, me ētahi atu.
(1) Te hanga i te polyester ārai mura
I whakamahia te Dop0 hei rauemi mata hei tauhohe ki te waikawa itaconic hei hanga i tētahi takawaenga, ko te odop-bda, ka taea te whakakapi i tētahi wāhanga o te ethylene glycol hei whiwhi i tētahi polyester ārai mura hou kei roto ko te phosphorus.
(2) Te hanga i te kapia epoxy ārai mura
He whānuitia te whakamahinga o te kapia epoxy i roto i ngā piripiri, ngā taputapu hiko, ngā mahi rererangi, ngā paninga me ngā rauemi hiato matatau nā te mea he pai rawa atu ōna āhuatanga piri me te ārai hiko. I te tau 2004, neke atu i te 200,000 tana ia tau te whakamahinga o te kapia epoxy i te ao.
(3) Te whakapai ake i te wairewatanga waro o ngā pūmua
(4) Hei takawaenga i roto i te hanganga o te antioxidant
(5) Ngā mea whakau mō ngā rauemi pūmua hangai
(6) Matua kanapa hangai
