Ziziphi iingenelo zokuhambelana kwe-p-hydroxyacetophenone kunye ne-polyols?

Ukuhambelana phakathii-p-hydroxyacetophenonekwaye i-polyols inika iingenelo ezininzi kwizicelo ezahlukeneyo. Nazi ezinye zeengenelo eziphambili:

Ukunyibilika:i-p-HydroxyacetophenoneIbonakalisa ukunyibilika okugqwesileyo kwiipolyols, nto leyo eyenza kube lula ukuyifaka kwiifomyula. Inokunyibilika ngokulula kwiinkqubo zepolyol zamanzi nezingezizo zamanzi, ivumela umxube ofanayo kunye nokusasazwa okufanayo kuyo yonke into.

Ukusebenza kwe-Reactive: i-p-Hydroxyacetophenone ineqela elisebenzayo le-reactive, iqela le-hydroxyl (OH), elinokuthatha inxaxheba kwiimpendulo ezahlukeneyo zeekhemikhali. Oku kuyenza ihambelane nee-polyols, ezikwaqulathe amaqela e-hydroxyl. Indlela esabela ngayo i-p-hydroxyacetophenone iyenza ikwazi ukuthatha inxaxheba kwiimpendulo ezidibanisayo, nto leyo ekhokelela ekwakhiweni kweenethiwekhi ze-polymer ezineempawu eziphuculweyo.

Iinkqubo ezinokunyangwa:i-p-HydroxyacetophenoneIsetyenziswa kakhulu njenge-photoinitiator kwiinkqubo ezinokunyangwa. Xa ivezwa kwi-UV okanye ekukhanyeni okubonakalayo, idlula kwi-photolysis ukuze ivelise ii-free radicals, eziqala i-polymerization okanye ii-crosslinking reactions. Ngokudibanisa i-p-hydroxyacetophenone kunye ne-polyols, kunokwenzeka ukuphuhlisa izinto ezinokunyangwa ezifana neengubo, izincamathelisi, kunye nee-composites zamazinyo. Ukuhambelana phakathi kwe-p-hydroxyacetophenone kunye ne-polyols kuqinisekisa i-photoinitiation esebenzayo kunye ne-crosslinking, ekhokelela kwiinkqubo zokunyanga ezikhawulezayo nezilawulwayo.

Iipropati ze-Antioxidant: i-p-Hydroxyacetophenone ibonisa iipropati ze-antioxidant, ezinokunceda iinkqubo ezisekwe kwi-polyol. Iinkqubo ze-oxidation zinokubangela ukuwohloka kunye nokulahleka kweempawu zezinto ngokuhamba kwexesha. Ngokufaka i-p-hydroxyacetophenone kwi-polyols, umsebenzi we-antioxidant unceda ukuthintela iimpendulo ze-oxidation, ukugcina ukuthembeka kunye nokusebenza kwezinto.

Ukuguquguquka: Ukuhambelana phakathi kwe-p-hydroxyacetophenone kunye ne-polyols kuvumela ukuguquguquka ekwenzeni iimveliso ezahlukeneyo. Ingasetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanya i-polyurethane foams, i-thermosetting resins, i-coatings, kunye neemveliso zokhathalelo lomntu. Ukukwazi ukudibanisa i-p-hydroxyacetophenone kunye ne-polyols ezahlukeneyo kunika ukuguquguquka ekulungiseleleni iimpawu zezinto zokugqibela ukuze zihlangabezane neemfuno ezithile.

Uzinzo: IiPolyols zaziwa ngokuzinza kwazo, kwaye ukuhambelana kwazo ne-p-hydroxyacetophenone akuchaphazeli kakhulu ukuzinza kwazo. Ukongezwa kwe-p-hydroxyacetophenone kwiipolyols akubeki emngciphekweni ubomi bazo beshelufu okanye kubangele ukubola kwangaphambi kwexesha, okuqinisekisa uzinzo lwexesha elide lweemveliso ezenziweyo.

Ngamafutshane, ukuhambelana phakathi kwe-p-hydroxyacetophenone kunye ne-polyols kunika iingenelo ezinje ngokunyibilika, ukusebenza okusebenzayo, ukuphiliswa kwe-photo, iipropati ze-antioxidant, ukuguquguquka, kunye nozinzo. Ezi nzuzo zenza ukuba ibe yinxalenye ebalulekileyo kwizicelo ezahlukeneyo, iphucula ukusebenza kunye neepropati zeenkqubo ezisekwe kwi-polyol.
