He otinga whakamarumaru mahi-teitei te whakamarumaru pahuka rehu, e rua ngā rauemi matua: te polyurethane me te isocyanate. Ka rongoa motuhaketia ngā wāhanga e rua, ā, kāore e whakaranua kia tae rā anō ki te wā e whakamahia ai. Kia whakaranua, ka pāngia e te tauhohenga matū ka nui haere te horapa o te ranunga, ka whakakī i ngā āputa me ngā wāhi uaua ki te tae atu. Ehara i te mea ka whakapai ake noa tēnei whakawhānui i te whakamarumaru, engari ka whakarato hoki i te ātete hau, ka pai ake te whai hua o te pūngao.
He pūhui maha ngā mahi a te polyurethane, koinei te pūtake o te pahuka rehu. He tino pai ōna āhuatanga ārai mate, ā, he kaha ki te hanga pahuka pakari, ngāwari hoki. He matū tauhohe te Isocyanate e mahi tahi ana me te polyurethane hei hanga i te hanganga pahuka. Ka tere te horapa o ēnei rauemi e rua ina whakamahia hei hanga i te pahuka matotoru e piri ana ki te mata, ā, he pai te ārai wera, te ātete ki te makuku, me te roa.
Ngā momo whakamarumaru pahuka rehu
E rua ngā momo matua o te whakamahana pahuka rehu e whakamahia ana i roto i te hanganga me te ahumahi:
Pahuka Rehu Pūtau-Tuwhera: He iti ake te mātotoru o tēnei pahuka, ā, he mea rongonui mō ngā mahi o roto. He āhuatanga whakaweto haruru, he tere ake hoki te horapa, ā, he whai hua ki te whakakī i ngā wāhi iti. He iti ake te utu me te ngāwari o te pahuka rehu pūtau-tuwhera i te pahuka rehu pūtau-kati.
Pahuka Rehu Pūtau-Katia: He nui ake te mātotoru o te pahuka rehu pūtau-katia, ā, he kaha ake hoki ōna āhuatanga ārai, ā, he maha ngā wā ka whakamahia ki ngā mahi o waho, ki ngā wāhi rānei e hiahiatia ana he ātete nui ki te makuku. Ka hangaia he ārai ā-wai, ā, he pai mō te whakamahi ki ngā tuanui, ki ngā rūma o raro, me ngā wāhi e pāngia ana e te makuku.
Te Tūranga oNgā Whakakōkī Polyurethane
I roto i te hanga o te whakamahana pahuka rehu, he mea nui te mahi a ngā whakakorikori polyurethane ki te akiaki i te tauhohenga matū i waenga i te polyurethane me te isocyanate. Ka whakahaere ēnei whakakorikori i te tere me te kounga o te tukanga pahuka, kia tika ai te whakawhanui o te pahuka, kia pai ai te whakamaroke, ā, kia tutuki ai ngā āhuatanga e hiahiatia ana, pērā i te pakari, te ātete wera, me te piri.
Tā mātou whakakorikori polyurethaneMXC-5He whakakorikori pahuka e ahu mai ana i te amine tuatoru e whakatairanga ana i te tauhohenga urea (wai-isocyanate) i roto i ngā momo whakamahinga pahuka polyurethane pakari me te ngāwari. Koinei te whakakorikori paerewa ahumahi e whakamahia ana i roto i ngā pūnaha polyurethane maka-ki-te-wāhi e ahu mai ana i te MDI, e āwhina ana ki te whakarite i te mahi pahuka me te ōritetanga tino pai.
Mā te whakamahi i te whakakorikori polyurethane tika, pērā i te MXC-5, ka tutuki te kaha katoa o tō pahuka rehu, me te whakarei ake i te whānui o te pahuka, ngā āhuatanga pakari, me te hanganga pai. Ahakoa kei te hanga koe i te pahuka rehu pūtau-tuwhera, pūtau-kati rānei, he mea nui te whiriwhiri i te whakakorikori tika hei whakatutuki i ngā paerewa mahi me te taiao.
He aha me whiriwhiri ai te kaiwhakaoho tika?
Me whiriwhiri e ngā kaihanga pahuka rehu te whakakorikori tika kia tutuki ai te whakamarumaru pahuka kounga teitei, pumau. Ka taea e te whakakorikori kua hangaia pai te:
- Whakapai ake i te whakawhānui me te wā whakamaroke o te pahuka.
- Whakapai ake i te piri ki ngā momo papa.
- Me whakarite kia iti ngā tukunga, kia tutuki hoki ngā paerewa ture.
- Whakaratohia he ātete makuku me te ātete wera pai ake.
