Ukuhambelana phakathip-hydroxyacetophenonekwaye iipolyols zibonelela ngeenzuzo ezininzi kwizicelo ezahlukeneyo.Nazi ezinye iingenelo eziphambili:
Ukunyibilika:p-Hydroxyacetophenoneibonisa ukunyibilika okugqwesileyo kwi-polyols, eyenza kube lula ukudibanisa kwimixube.Iyakwazi ukunyibilika ngokulula kuzo zombini iinkqubo ze-polyol ezinamanzi kunye ne-non-aqueous, ezivumela ukuxutywa kwe-homogeneous kunye nokusabalalisa okufanayo kuyo yonke into.
Ukusebenza okusebenzayo: i-p-Hydroxyacetophenone ineqela elisebenzayo elisebenzayo, iqela le-hydroxyl (OH), elinokuthatha inxaxheba kwiindlela ezahlukeneyo zemichiza.Oku kuyenza ihambelane neepolyols, ekwanamaqela e-hydroxyl.Ubume obusebenzayo be-p-hydroxyacetophenone buyenza ukuba ithathe inxaxheba kwiindlela ezihlanganayo, okukhokelela ekwenziweni kothungelwano lwepolymer eneempawu ezongeziweyo.
Iinkqubo ezithathekayo:p-Hydroxyacetophenoneisetyenziswa ngokuqhelekileyo njengefotoinitiator kwiinkqubo ezikwazi ukufotokopa.Xa ibonakaliswe kwi-UV okanye ekukhanyeni okubonakalayo, i-photolysis yenza i-radicals yamahhala, eqalisa i-polymerization okanye i-crosslinking reactions.Ngokudibanisa i-p-hydroxyacetophenone kunye ne-polyols, kunokwenzeka ukuba kuphuhliswe izinto ezikwazi ukufotokopa ezifana neengubo, i-adhesives, kunye ne-composites yamazinyo.Ukuhambelana phakathi kwe-p-hydroxyacetophenone kunye ne-polyols iqinisekisa ukufotowa ngokufanelekileyo kunye nokudibanisa, okukhokelela kwiinkqubo zokunyanga ngokukhawuleza kunye nokulawulwa.
Iimpawu ze-Antioxidant: i-p-Hydroxyacetophenone ibonisa iimpawu ze-antioxidant, ezinokuthi zizuze iinkqubo ezisekelwe kwi-polyol.Iinkqubo ze-oxidation zingabangela ukuthotywa kunye nokulahlekelwa kwezinto eziphathekayo ngokuhamba kwexesha.Ngokudibanisa i-p-hydroxyacetophenone kwi-polyols, umsebenzi we-antioxidant unceda ukuthintela ukuphendula kwe-oxidation, ukugcina ingqibelelo kunye nokusebenza kwezinto eziphathekayo.
I-Versatility: Ukuhambelana phakathi kwe-p-hydroxyacetophenone kunye ne-polyols ivumela ukuguquguquka ekuqulunqweni kweemveliso ezahlukeneyo.Ingasetyenziswa kuluhlu olubanzi lwezicelo, kubandakanywa amagwebu e-polyurethane, ii-resin ze-thermosetting, iingubo, kunye neemveliso zokunyamekela.Ukukwazi ukudibanisa i-p-hydroxyacetophenone kunye ne-polyols ehlukeneyo ibonelela ngokuguquguqukayo ekulungiseni iipropati zezinto zokugqibela ukuhlangabezana neemfuno ezithile.
Ukuzinza: Iipolyols ziyaziwa ngokuzinza kwazo, kwaye ukuhambelana ne-p-hydroxyacetophenone akuchaphazeli kakhulu ukuzinza kwazo.Ukongezwa kwe-p-hydroxyacetophenone kwii-polyols akuphazamisi ubomi babo beshelufu okanye kubangele ukuthotywa kwangaphambi kwexesha, ukuqinisekisa ukuzinza kwexesha elide kwiimveliso ezenziweyo.
Isishwankathelo, ukuhambelana phakathi kwe-p-hydroxyacetophenone kunye ne-polyols kunika izibonelelo ezinjengokunyibilika, ukusebenza okusebenzayo, ukufota, iipropathi ze-antioxidant, ukuguquguquka, kunye nokuzinza.Ezi zibonelelo zenza ukuba ibe yinto exabisekileyo kwizicelo ezahlukeneyo, ukuphucula ukusebenza kunye neempawu zeenkqubo ezisekelwe kwi-polyol.
