Kuenderana pakatip-hydroxyacetophenoneuye polyols ine mabhenefiti akawanda mukushandiswa kwakasiyana-siyana. Heano mamwe mabhenefiti akakosha:
Kunyunguduka:p-HydroxyacetophenoneInoratidza kunyungudika kwakanaka muma polyols, izvo zvinoita kuti zvive nyore kuisa mumafomura. Inogona kunyungudika nyore nyore muma polyol systems emvura neasiri emvura, zvichibvumira musanganiswa wakafanana uye kupararira kwakafanana mukati mezvinhu zvese.
Mashandiro ekuita reactive: p-Hydroxyacetophenone ine boka rekuita reactive, iro hydroxyl (OH), iro rinogona kutora chikamu mumaitiro akasiyana-siyana emakemikari. Izvi zvinoita kuti ienderane nemapolyol, ayo anewo mapoka ehydroxyl. Hunhu hwekuita reactive hwep-hydroxyacetophenone hunoita kuti ikwanise kutora chikamu mukuita reconnecting, zvichikonzera kuumbwa kwema polymer network ane hunhu hwakawedzerwa.
Masisitimu anorapika:p-HydroxyacetophenoneInowanzoshandiswa semuchina wekugadzira mifananidzo mumasisitimu anorapika. Kana ikasangana neUV kana chiedza chinoonekwa, inorapika kuti igadzire mafree radicals, ayo anotanga polymerization kana crosslinking reactions. Nekubatanidza p-hydroxyacetophenone nepolyols, zvinokwanisika kugadzira zvinhu zvinorapika zvakaita semachira, manamati, uye macomposites emazino. Kuenderana pakati pep-hydroxyacetophenone nepolyols kunoita kuti photoinitiation ishande zvakanaka uye crosslinking, zvichitungamira mukuita kwekukurumidza uye kudzora maitiro ekurapa.
Hunhu hweAntioxidant: p-Hydroxyacetophenone inoratidza hunhu hweAntioxidant, izvo zvinogona kubatsira masisitimu ane polyol. Maitiro eOxidation anogona kukonzera kuora uye kurasikirwa nehunhu hwezvinhu nekufamba kwenguva. Nekuisa p-hydroxyacetophenone mu polyols, basa reAntioxidant rinobatsira kudzivirira maitiro eOxidation, kuchengetedza kusimba uye kushanda kwechinhu chacho.
Kuchinja-chinja: Kuenderana pakati pep-hydroxyacetophenone nepolyols kunobvumira kushandiswa kwakasiyana-siyana mukugadzira zvigadzirwa zvakasiyana. Inogona kushandiswa mumhando dzakasiyana-siyana, kusanganisira polyurethane foams, thermosetting resins, coatings, uye zvigadzirwa zvekuchengetedza munhu. Kukwanisa kusanganisa p-hydroxyacetophenone nepolyols dzakasiyana kunoita kuti pave nekuchinjika mukugadzirisa hunhu hwechinhu chekupedzisira kuti chienderane nezvinodiwa chaizvo.
Kugadzikana: Polyols inozivikanwa nekugadzikana kwayo, uye kushanda kwayo ne p-hydroxyacetophenone hakukanganisi zvakanyanya kugadzikana kwayo. Kuwedzerwa kwe p-hydroxyacetophenone kuma polyols hakukanganisi nguva yayo yekuchengetera kana kukonzera kuora nguva isati yakwana, zvichiita kuti zvigadzirwa zvakagadzirwa zvigare kwenguva refu.
Muchidimbu, kubatana kuripo pakati pe p-hydroxyacetophenone ne polyols kune zvakanakira zvakaita sekunyungudika, kushanda kwe reactive, kugona kupora, hunhu hwe antioxidant, kushanduka-shanduka, uye kugadzikana. Zvakanakira izvi zvinoita kuti ive chinhu chakakosha mumashandisirwo akasiyana-siyana, zvichivandudza mashandiro uye hunhu hwe polyol-based systems.
