He rauemi hanga maha ngā mahi a te papa hanawiti, e toru ngā paparanga: e rua ngā paparanga o waho (ngā whakaotinga rānei) me te paparanga matua i waenganui. Ko tētahi o ngā rauemi paparanga matua tino noa ko te pahuka polyurethane (PU), he pai rawa ngā āhuatanga whakamahana me te tautoko hanganga. Ko te paparanga matua kei waenganui i ngā whakaotinga pakari, he mea hanga ki te konganuku, ki te kirihou, ki ngā rauemi hiato kua whakapakarihia ki te muka rānei, e whakanui ana i te kaha me te roa o te panera. Ko ngā wāhanga matua i roto i te hanga o ngā paparanga matua pahuka polyurethane mahi teitei mō ngā panera hanawiti ko ngā whakakorikori polyurethane, pērā i te MXC-15 me te MXC-37.
He aha te pahuka polyurethane?
E whakamahia whānuitia ana ngā matua pahuka polyurethane i roto i ngā panera hanawiti nā te mea he pai te uara whakamahana (he nui te uara-R), he māmā te āhua, me te tautoko hanganga. E whakamahia whānuitia ana ēnei panera i roto i ngā ahumahi e hiahiatia ana te whakamahana wera me te hanganga pai, pēnei i:
- Hanganga: He tino pai te whakamarumaru o ngā rauemi matua, ā, ka pai ake te penapena pūngao o ngā whare. Hei tauira, i a mātou e mahi ana i tētahi whare rokiroki makariri, i tino whakaitihia ngā utu pūngao e ngā panera hanawiti whakamarumaru mā te pupuri i te pāmahana ōrite.
- Te Pouaka Whakamātao me te Rokiroki MataoI roto i ngā whare rokiroki makariri, he mea nui te whakamahi i ngā uara whakamarumaru teitei hei pupuri i te pāmahana iti.Nā te ātete o te pahuka polyurethane ki te whakawhiti wera, he whānuitanga tēnei mea hei whakamahi mā ngā rūma makariri me ngā waeine whakamatao.
- Te Rererangi me te MoanaI roto i ngā mahi rererangi me te moana, he mea nui te taurite i waenga i te taumaha me te kaha. Ko ngā panera hanawiti me ngā matua pahuka PU e whakarato ana i te tautoko hanganga e hiahiatia ana me te whakaiti i te taumaha.
Te Tūranga oNgā Whakakōkī Polyurethane
He mea nui ngā whakakorikori polyurethane, pērā i te MXC-15 me te MXC-37, i roto i te tauhohenga huka i te wā e hangaia ana ngā matua huka polyurethane. Ka tere ake ngā tauhohenga matū i waenga i te polyol me te isocyanate e ēnei whakakorikori, ka taea ai te hanga i tētahi pahuka pumau me ngā āhuatanga e hiahiatia ana.
MXC-15: He whakakorikori isocyanurate whai hua, he ohanga hoki, he tere tahuritanga teitei. He pai mō te hanganga polyol matotoru teitei, e whakatairanga ana i te tauhohenga isocyanate, he kaha teitei, e whakamahia ana mō te pahuka mārō PU, tae atu ki te pahuka rehu, te pahuka PIR, te pūnaha pahuka PIR.
MXC-37: E mōhiotia ana ko te DMAEE, mā te tāpiri i te DMAEE ki te pūhui ka whakaiti i te haunga amine e kitea ana i roto i ngā pahuka. Ka taea te whakamahi hei whakakorikori matua anake, hei whakakorikori tahi rānei hei whakaiti i te whakamahinga o ngā whakakorikori pahuka BDMAEE. Mō ngā whakaū e hangai ana ki te ester, ka whakamahia te pahuka ngohengohe, te pahuka moroiti, te elastomer, te RIM me te RRIM, me ngā tono takai pahuka pakari.
Ngā Painga o te Pahuka Polyurethane i roto i ngā Paewhiri Hanawiti
- Āraitanga Pai Rawa (Uara-R)Ko te pahuka polyurethane tētahi o ngā uara-R teitei rawa atu mō ia inihi ki te whakaritea ki ētahi atu rauemi whakamahana. Nā tēnei ka tino penapena pūngao ngā panera hanawiti me ngā matua pahuka PU.
- Mama, ā, he pakariKa whakaitihia e ngā matua pahuka PU te taumaha katoa o te papa hanawiti me te kore e whakararu i te kaha, he mea tino pai mō ngā tono e matua ana te whakaiti i te taumaha.
- Ātete ki te makuku me te ahiKa taea te hanga i te pahuka polyurethane me ngā tāpiringa hei whakarei ake i te ātete ahi me te ātete makuku, hei whakapai ake i te haumaru me te roa o te ora o ngā panera hanawiti i roto i ngā taiao rerekē.
- Te Matotoru me te Kaha e Taea te WhakariteMā te whakarerekē i te whakatakotoranga me ngā whakakorikori, ka taea e ngā kaihanga te whakaputa pahuka me ngā momo matotoru me ngā āhuatanga hangarau rerekē, kia taea ai e ngā panera hanawiti te whakatutuki i ngā whakaritenga tono motuhake.
Whakamutunga
He mea nui ngā whakakōkī polyurethane pēnei i te MXC-15 me te MXC-37 mō te hanga i ngā matua pahuka polyurethane mahi-teitei mō ngā panera hanawiti. Mā ēnei whakakōkī ka tutuki te pahuka i ngā whakaritenga e hiahiatia ana, pēnei i te uara whakamarumaru teitei, te kaha hanganga, me te roa. Ko te urutau o te pahuka polyurethane, me te tika o ngā whakakōkī hou, kua whakau i tōna tūranga i roto i ngā ahumahi mai i te hanga ki te pouaka whakamātao, te motuka, me te rererangi. Mā ngā auahatanga i roto i ngā whakatakotoranga whakakōkī, ka taea e ngā kaihanga te whakapai tonu i te mahi me te pumau o ngā panera hanawiti.
