Ko te hototahitanga i waenga ip-hydroxyacetophenoneā, he maha ngā painga o ngā polyol i roto i ngā momo whakamahinga. Anei ētahi painga matua:
Te wairewatanga:p-HydroxyacetophenoneHe tino pai te wairewatanga ki roto i ngā polyol, ā, he māmā noa iho te whakauru ki roto i ngā hanganga. Ka taea te wairewa ngāwari ki roto i ngā pūnaha polyol wai me ngā pūnaha polyol kore-wai, e āhei ai te ranunga ōrite me te tohatoha ōrite puta noa i te rauemi.
Mahi tauhohe: Kei te p-Hydroxyacetophenone tētahi rōpū mahi tauhohe, arā, te rōpū hydroxyl (OH), ka taea te whai wāhi ki ngā tauhohenga matū maha. Nā tēnei ka hototahi ki ngā polyol, kei roto hoki ngā rōpū hydroxyl. Nā te āhua tauhohe o te p-hydroxyacetophenone ka taea e ia te whai wāhi ki ngā tauhohenga hononga whakawhiti, ka hua ake te hanganga o ngā whatunga polymer me ngā āhuatanga whakarei ake.
Ngā pūnaha whakaora whakaahua:p-Hydroxyacetophenonee whakamahia whānuitia ana hei kaiwhakaoho whakaahua i roto i ngā pūnaha whakaora whakaahua. Ina pāngia e te mārama UV, e te mārama kitea rānei, ka pāngia e te whakaora whakaahua hei whakaputa i ngā rauropi kore utu, e tīmata ai te whakakotahitanga, te tauhohenga hononga rānei. Mā te whakakotahi i te p-hydroxyacetophenone me ngā polyol, ka taea te whakawhanake i ngā rauemi whakaora whakaahua pēnei i ngā paninga, ngā piripiri, me ngā hiato niho. Ko te hototahi i waenga i te p-hydroxyacetophenone me ngā polyol ka whakarite i te whakaora whakaahua me te hononga whakawhiti whai hua, ka hua ake he tukanga whakaora tere me te whakahaere.
Ngā āhuatanga ārai mate: Kei te whakaatu te p-Hydroxyacetophenone i ngā āhuatanga ārai mate, ka whai hua ki ngā pūnaha polyol. Ka taea e ngā tukanga whakahāngai te whakararu me te ngaronga o ngā āhuatanga o te rauemi i roto i te wā. Mā te whakauru i te p-hydroxyacetophenone ki roto i ngā polyol, ka āwhina te mahi ārai mate ki te aukati i ngā tauhohenga whakahāngai, me te tiaki i te kounga me te mahi o te rauemi.
Ngā Mahi Whānui: Mā te hototahitanga i waenga i te p-hydroxyacetophenone me ngā polyol ka taea te whakamahi whānuitia i roto i te hanga hua rerekē. Ka taea te whakamahi i roto i te whānuitanga o ngā tono, tae atu ki ngā pahuka polyurethane, ngā kapia thermosetting, ngā paninga, me ngā hua tiaki whaiaro. Mā te kaha ki te whakakotahi i te p-hydroxyacetophenone me ngā polyol rerekē ka taea te whakarite i ngā āhuatanga o te rauemi whakamutunga kia tutuki ai ngā whakaritenga motuhake.
Pūmautanga: E mōhiotia ana ngā polyol mō tō rātou pumau, ā, kāore te hototahitanga ki te p-hydroxyacetophenone e tino pā ki tō rātou pumau ā-roto. Kāore te tāpiri o te p-hydroxyacetophenone ki ngā polyol e whakararu i tō rātou roa o te rokiroki, e kore hoki e pirau wawe, e whakarite ana i te pumau mō te wā roa o ngā hua kua hangaia.
Hei whakarāpopototanga, ko te hototahitanga i waenga i te p-hydroxyacetophenone me ngā polyol he painga pēnei i te wairewa, te mahi tauhohe, te kaha ki te whakaora i te whakaahua, ngā āhuatanga antioxidant, te maha o ngā whakamahinga, me te pumau. Nā ēnei painga ka waiho hei wāhanga nui i roto i ngā tono maha, ka whakarei ake i te mahi me ngā āhuatanga o ngā pūnaha e hangai ana ki te polyol.
