Te ōwehenga o te polyol me te isocyanate:

He nui te uara hydroxyl o te Polyol, ā, he nui te taumaha ngota, ka whakanui ake i te kiato hononga whakawhiti, ka āwhina hoki ki te whakapai ake i te kiato pahuka. Mā te whakarerekē i te taupū isocyanate, arā, te ōwehenga molar o te isocyanate ki te hauwai hohe i roto i te polyol, ka whakanui ake i te taumata o te hononga whakawhiti, ka whakanui ake hoki i te kiato. I te nuinga o te wā, ko te taupū isocyanate kei waenga i te 1.0-1.2.

 

Te kōwhiringa me te horopeta o te kaihoko pahuka:

Ka pā tika te momo me te horopeta o te kaipupuku ki te tere o te horapa o te hau me te mātotoru o te mirumiru i muri i te pupuhi, ā, ka pā anō hoki ki te matotoru o te kirinuku. Mā te whakaiti i te horopeta o te kaipupuku ā-tinana ka taea te whakaiti i te porosity o te pahuka me te whakanui ake i te mātotoru. Hei tauira, ko te wai, hei kaipupuku matū, ka tauhohe ki te isocyanate hei whakaputa i te hauhā waro. Mā te whakanui ake i te nui o te wai ka whakaiti i te mātotoru o te pahuka, ā, me tino whakahaere te nui o tōna tāpiri.

 

Te nui o te whakakorikori:

Me whakarite e te kaiwhakakōkī kia taurite te tauhohenga huka me te tauhohenga tiēre i roto i te tukanga huka, ki te kore ka hinga, ka mimiti rānei te mirumiru. Mā te whakakotahi i tētahi matū amine tuatoru kaha kawakore he pānga whakakōkī kaha ki te tauhohenga huka me te pānga whakakōkī kaha ki te tauhohenga tiēre, ka taea te whiwhi i tētahi kaiwhakakōkī e tika ana mō te pūnaha kiri-ake.

 

Whakahaere pāmahana:

Te pāmahana pokepokea ai: Ka piki ake te matotoru o te kiri i te hekenga o te pāmahana pokepokea ai. Mā te whakanui ake i te pāmahana pokepokea ai ka tere ake te tere o te tauhohenga, ka pai ake te hanganga kiato, ka piki ake te kiato, engari mā te pāmahana nui rawa ka kore e taea te whakahaere i te tauhohenga. Ko te tikanga, ka whakahaerehia te pāmahana pokepokea ai i te 40-80℃.

 

Te pāmahana pakari:

Mā te whakahaere i te pāmahana koroheketanga ki te 30-60℃ me te wā ki te 30s-7min ka taea te whiwhi i te taurite tino pai i waenga i te kaha tango me te whai huatanga o te whakaputa o te hua.

 

Whakahaere pēhanga:

Mā te whakanui ake i te pēhanga i te wā e whakaputa huka ana ka ārai i te whānui o ngā mirumiru, ka whakawhāiti ake i te hanganga o te pahuka, ka whakanui ake hoki i te mātotoru. Heoi, mā te pēhanga nui rawa ka nui ake ngā whakaritenga mō te pokepokea ai, ka piki ake hoki te utu.

 

Te tere whakaoho:

Mā te whakanui tika i te tere o te whakaoho ka taea te whakaranu i ngā rauemi mata kia ōrite, kia tino tauhohe, ā, ka āwhina i te whakanui ake i te mātotoru. Heoi, ki te tere rawa te whakaoho ka nui rawa te hau ka puta, ka heke te mātotoru, ā, ko te tikanga ka whakahaeretia i te 1000-5000 rpm.

 

Tauwehenga whakakī rawa:

Me nui ake te nui o te werohanga o te ranunga tauhohenga o te hua whakakoi-ake i te nui o te werohanga o te pahuka kore utu. I runga i te hua me te pūnaha rauemi, ko te tauwehenga whakakī nui ko te 50%-100% hei pupuri i te pēhanga pokepokea ai te teitei, he mea e pai ai te wai o te kaihoko pahuka i roto i te paparanga kiri.

 

Te wā whakaōrite i te paparanga kiri:

I muri i te ringihanga o te polyurethane pahuka ki roto i te tauira, ka roa te mata e whakatauritea ana, ka matotoru ake te kiri. Ko te whakahaere tika i te wā whakataurite i muri i te ringihanga tētahi o ngā huarahi hei whakahaere i te matotoru o te kiri.
