Ukuhambisana phakathii-p-hydroxyacetophenonekanye ne-polyols inikeza izinzuzo eziningana ezinhlelweni ezahlukene. Nazi ezinye izinzuzo ezibalulekile:
Ukuncibilika:i-p-Hydroxyacetophenoneikhombisa ukuncibilika okuhle kakhulu kuma-polyol, okwenza kube lula ukuyifaka ekwakhiweni. Ingancibilika kalula kokubili ezinhlelweni ze-polyol zamanzi nezingezona ezamanzi, okuvumela ukuhlanganiswa okufanayo kanye nokusatshalaliswa okufanayo kuyo yonke into.
Ukusebenza okusabelayo: i-p-Hydroxyacetophenone ineqembu elisebenzayo elisabelayo, iqembu le-hydroxyl (OH), elingabamba iqhaza ekusabeleni okuhlukahlukene kwamakhemikhali. Lokhu kuyenza ihambisane nama-polyol, aqukethe namaqembu e-hydroxyl. Uhlobo lokusabela lwe-p-hydroxyacetophenone luyenza ikwazi ukuhlanganyela ekusabeleni okuxhumanisayo, okuholela ekwakhekeni kwamanethiwekhi e-polymer anezakhiwo ezithuthukisiwe.
Izinhlelo ezithwetshulwa ngezithombe:i-p-Hydroxyacetophenoneivame ukusetshenziswa njenge-photoinitiator ezinhlelweni ezithwetshulwa yilanga noma ukukhanya okubonakalayo. Uma ivezwa ku-UV noma ekukhanyeni okubonakalayo, idlula ku-photolysis ukuze ikhiqize ama-free radicals, aqala ukwenziwa kwe-polymerization noma ukusabela kokuxhumanisa. Ngokuhlanganisa i-p-hydroxyacetophenone nama-polyol, kungenzeka ukuthuthukisa izinto ezithwetshulwa yilanga ezifana nokumbozwa, izinamathiseli, kanye nezinhlanganisela zamazinyo. Ukuhambisana phakathi kwe-p-hydroxyacetophenone nama-polyol kuqinisekisa ukwenziwa kwe-photoinitiation okuphumelelayo kanye nokuxhumanisa, okuholela ezinqubweni zokuphulukisa ezisheshayo nezilawulwayo.
Izakhiwo ze-Antioxidant: i-p-Hydroxyacetophenone ibonisa izakhiwo ze-antioxidant, ezingazuzisa izinhlelo ezisekelwe ku-polyol. Izinqubo ze-oxidation zingabangela ukuwohloka nokulahlekelwa yizakhiwo zezinto ngokuhamba kwesikhathi. Ngokufaka i-p-hydroxyacetophenone kuma-polyol, umsebenzi we-antioxidant usiza ukuvimbela ukusabela kwe-oxidation, ukulondoloza ubuqotho nokusebenza kwezinto.
Ukuguquguquka: Ukuhambisana phakathi kwe-p-hydroxyacetophenone nama-polyol kuvumela ukuguquguquka ekwakhiweni kwemikhiqizo ehlukene. Ingasetshenziswa ezinhlobonhlobo zezicelo, kufaka phakathi ama-polyurethane foam, ama-thermosetting resins, izembozo, kanye nemikhiqizo yokunakekela umuntu siqu. Amandla okuhlanganisa i-p-hydroxyacetophenone nama-polyol ahlukahlukene anikeza ukuguquguquka ekuhleleni izakhiwo zezinto zokugcina ukuze kuhlangatshezwane nezidingo ezithile.
Ukuzinza: Ama-Polyol ayaziwa ngokuzinza kwawo, futhi ukuhambisana ne-p-hydroxyacetophenone akukuthinti kakhulu ukuzinza kwawo okungokwemvelo. Ukwengezwa kwe-p-hydroxyacetophenone kuma-polyol akubeki engcupheni impilo yawo eshalofini noma kubangele ukuwohloka kwangaphambi kwesikhathi, okuqinisekisa ukuzinza kwesikhathi eside kwemikhiqizo eklanyiwe.
Ngamafuphi, ukuhambisana phakathi kwe-p-hydroxyacetophenone kanye ne-polyols kunikeza izinzuzo ezifana nokuncibilika, ukusebenza okusabelayo, ukuphiliswa kwe-photo, izakhiwo ze-antioxidant, ukuguquguquka, kanye nokuqina. Lezi zinzuzo zenza kube yingxenye ebalulekile ezinhlelweni ezahlukahlukene, okuthuthukisa ukusebenza kanye nezakhiwo zezinhlelo ezisekelwe ku-polyol.
