Melemo ea ho lumellana ha p-hydroxyacetophenone le polyols ke efe?

Ho tsamaellana pakeng tsap-hydroxyacetophenonele polyols li fana ka melemo e 'maloa lits'ebetsong tse fapaneng. Mona ke melemo e meng ea bohlokoa:

Ho qhibiliha ha metsi:p-HydroxyacetophenoneE na le ho qhibiliha ho babatsehang ho polyols, e leng se etsang hore ho be bonolo ho e kenyelletsa mefuteng. E ka qhibiliha habonolo lits'ebetsong tsa polyol tse metsi le tse seng metsi, e leng se lumellang metsoako e ts'oanang le kabo e ts'oanang ho pholletsa le thepa.

Tshebetso e sebetsang: p-Hydroxyacetophenone e na le sehlopha se sebetsang se sebetsang, sehlopha sa hydroxyl (OH), se ka nkang karolo liketsong tse fapaneng tsa lik'hemik'hale. Sena se etsa hore e lumellane le li-polyol, tse nang le lihlopha tsa hydroxyl. Tlhaho ea ho arabela ea p-hydroxyacetophenone e e nolofalletsa ho nka karolo liketsong tse kopanyang, e leng se fellang ka ho thehoa ha marang-rang a polymer a nang le thepa e ntlafalitsoeng.

Mekhoa e ka folisoang:p-Hydroxyacetophenonee atisa ho sebelisoa e le sesebelisoa sa ho qala ho foka ha lisele lits'ebetsong tse ka fokang. Ha e pepesetsoa UV kapa khanya e bonahalang, e etsoa photolysis ho hlahisa li-free radicals, tse qalang polymerization kapa li-crosslinking reactions. Ka ho kopanya p-hydroxyacetophenone le polyols, hoa khoneha ho hlahisa thepa e ka fokang ha lisele tse kang lipente, likhomaretsi le metsoako ea meno. Ho lumellana pakeng tsa p-hydroxyacetophenone le polyols ho netefatsa ho qala ho foka ha lisele le ho kopanya lisele ka katleho, e leng se lebisang lits'ebetsong tsa ho fola tse potlakileng le tse laoloang.

Litšobotsi tsa Antioxidant: p-Hydroxyacetophenone e bonts'a litšobotsi tsa antioxidant, tse ka thusang litsamaiso tse thehiloeng ho polyol. Mekhoa ea ho ntša oksijene e ka baka ho senyeha le ho lahleheloa ke litšobotsi tsa thepa ha nako e ntse e ea. Ka ho kenyelletsa p-hydroxyacetophenone ho polyols, ts'ebetso ea antioxidant e thusa ho thibela liketso tsa oxidation, ho boloka botšepehi le ts'ebetso ea thepa.

Ho feto-fetoha ha lintho: Ho lumellana ha p-hydroxyacetophenone le polyols ho lumella ho feto-fetoha ha lintho ho theheng lihlahisoa tse fapaneng. E ka sebelisoa lits'ebetsong tse fapaneng, ho kenyeletsoa le foam ea polyurethane, li-resin tsa thermosetting, liphahlo le lihlahisoa tsa tlhokomelo ea botho. Bokhoni ba ho kopanya p-hydroxyacetophenone le polyols tse fapaneng bo fana ka ho feto-fetoha ha thepa ea ho qetela ho fihlela litlhoko tse itseng.

Botsitso: Li-polyol li tsebahala ka botsitso ba tsona, 'me ho lumellana ha tsona le p-hydroxyacetophenone ha ho ame botsitso ba tsona ba tlhaho haholo. Ho eketsoa ha p-hydroxyacetophenone ho li-polyol ha ho behe bophelo ba tsona ba polokelo kotsing kapa ho baka ho senyeha pele ho nako, ho netefatsa botsitso ba nako e telele ba lihlahisoa tse entsoeng.

Ka bokhutšoanyane, ho lumellana pakeng tsa p-hydroxyacetophenone le polyols ho fana ka melemo e kang ho qhibiliha, ts'ebetso e arabelang, ho fola habonolo, thepa ea antioxidant, ho tenyetseha le botsitso. Melemo ena e etsa hore e be karolo ea bohlokoa lits'ebetsong tse fapaneng, e ntlafatsa ts'ebetso le thepa ea litsamaiso tse thehiloeng ho polyol.
