Kedu uru dị na ndakọrịta nke p-hydroxyacetophenone na polyols?

Ndakọrịta dị n'etitip-hydroxyacetophenonena polyols na-enye ọtụtụ uru na ngwa dị iche iche. Lee ụfọdụ isi uru:

Mgbaze:p-Hydroxiacetophenonena-egosipụta ezigbo ike ịgbaze na polyols, nke na-eme ka ọ dị mfe itinye ya na nhazi. Ọ nwere ike ịgbaze ngwa ngwa na sistemụ polyol mmiri na nke na-abụghị mmiri, na-enye ohere maka ngwakọta ndị yiri ibe ha na nkesa otu nhata n'ime ihe ahụ dum.

Ọrụ mmeghachi omume: p-Hydroxyacetophenone nwere otu ọrụ mmeghachi omume, otu hydroxyl (OH), nke nwere ike isonye na mmeghachi omume kemịkalụ dị iche iche. Nke a na-eme ka ọ dakọọ na polyols, nke nwekwara otu hydroxyl. Ọdịdị mmeghachi omume nke p-hydroxyacetophenone na-eme ka ọ nwee ike isonye na mmeghachi omume njikọta, na-ebute ịmepụta netwọk polymer nwere njirimara ka mma.

Sistemụ ndị a na-ahụ maka foto:p-HydroxiacetophenoneA na-ejikarị ya eme ihe dị ka ihe na-eme ka foto malite na sistemụ ndị a na-agwọ. Mgbe a na-ekpughe ya na UV ma ọ bụ ìhè a na-ahụ anya, ọ na-eme photolysis iji mepụta radicals efu, nke na-amalite polymerization ma ọ bụ crosslinking reactions. Site na ijikọta p-hydroxyacetophenone na polyols, ọ ga-ekwe omume ịmepụta ihe ndị a na-agwọ photography dị ka mkpuchi, ihe nrapado, na ihe mejupụtara ezé. Ndakọrịta dị n'etiti p-hydroxyacetophenone na polyols na-eme ka foto mmalite na njikọta dị irè, na-eduga na usoro ọgwụgwọ ngwa ngwa na nke a na-achịkwa.

Njirimara antioxidant: p-Hydroxyacetophenone na-egosipụta ihe antioxidant, nke nwere ike ịba uru na sistemụ polyol. Usoro oxidation nwere ike ibute mmebi na mfu nke ihe onwunwe ka oge na-aga. Site na itinye p-hydroxyacetophenone n'ime polyols, ọrụ antioxidant na-enyere aka igbochi mmeghachi omume oxidation, na-echekwa iguzosi ike n'ezi ihe na arụmọrụ nke ihe ahụ.

Ịdị n'otu: Ndakọrịta dị n'etiti p-hydroxyacetophenone na polyols na-enye ohere maka ọtụtụ ihe dị iche iche n'ịmepụta ngwaahịa dị iche iche. Enwere ike iji ya mee ihe n'ọtụtụ ụzọ dị iche iche, gụnyere ụfụfụ polyurethane, resin thermosetting, mkpuchi, na ngwaahịa nlekọta onwe onye. Ike ijikọta p-hydroxyacetophenone na polyol dị iche iche na-enye mgbanwe n'ịhazi ihe onwunwe nke ihe ikpeazụ iji mezuo ihe achọrọ kpọmkwem.

Ịkwụsi Ike: A maara Polyols maka nkwụsi ike ha, ndakọrịta ha na p-hydroxyacetophenone anaghị emetụta nkwụsi ike ha nke ukwuu. Mgbakwunye nke p-hydroxyacetophenone na polyols anaghị emebi ndụ nchekwa ha ma ọ bụ kpatara mmebi tupu oge eruo, na-eme ka ngwaahịa ndị e mepụtara kwụsie ike ogologo oge.

Na nchịkọta, ndakọrịta dị n'etiti p-hydroxyacetophenone na polyols na-enye uru dịka ịgbaze, ọrụ mmeghachi omume, ime ka foto gwọọ, ihe ndị na-egbochi antioxidant, mgbanwe, na nkwụsi ike. Uru ndị a na-eme ka ọ bụrụ ihe bara uru na ngwa dị iche iche, na-eme ka arụmọrụ na njirimara nke sistemụ dabere na polyol dịkwuo mma.
