He maha ngā whakamahinga o ngā pahuka polyurethane, ā, kua noho hei rauemi nui mō ngā ahumahi maha. Ko ngā momo pahuka polyurethane e tino kitea ana ko ngā pahuka pūtau-katia me ngā pahuka pūtau-tuwhera, ā, he āhuatanga ahurei ō rāua e rua e tika ana mō ngā whakamahinga rerekē. Ko te hanga o ēnei pahuka e whakawhirinaki nui ana ki ngā whakakorikori polyurethane, e whai wāhi nui ana ki te whakahaere i ngā tauhohenga matū e hoatu ana ki ēnei pahuka ō rāua āhuatanga ahurei.
I roto i tēnei tuhinga, ka tūhuratia e mātou ngā rerekētanga i waenga i ngā pahuka pūtau-katia me ngā pahuka pūtau-tuwhera, ō rātou whakamahinga, me pēhea te āwhina a ngā whakakorikori polyurethane i tō rātou whakaputanga.
Pahuka Pūtau-Katia me te Pahuka Pūtau-Tuwhera: He Whakataurite Taipitopito
Huka Pūtau-Katia
Pahuka pūtau-kati He pahuka mārō, matotoru hoki e tuku ana i ngā uara whakamarumaru teitei ake, me te hanganga pakari ake i te pahuka pūtau-tuwhera. Katia ōna pūwero, ka ārai i te hau, i te makuku rānei kia puta, ka hua ake he ātete wai teitei ake, he mea tino pai mō ngā tono e hiahia ana kia tiakina te makuku.
Kiato: Ko te awhe mātotoru o te pahuka pūtau-katia he 2 ki te 3 pauna ia putu kūpiko, e hua ai he pakari me te kaha hanganga.
Ārai Wera: Nā te hanganga pūmau o te pūtau, he tino pai ōna āhuatanga whakamarumaru wera, ko te uara-R (ātete wera) he 6 ki te 7 ia inihi te tikanga. Nā tēnei he mea tino pai mō te whakamarumaru i ngā pakitara, i ngā tuanui, me ngā mahi rokiroki makariri.
Ātete ki te makuku: Kāore te pahuka pūtau-katia e uru ki te wai, he mea tino pai mō te noho ki te makuku, pērā i ngā mahi moana, i ngā rūma raro whenua rānei.
Ngā Whakamahinga: E whakamahia whānuitia ana i roto i te whakamahana pahuka rehu, i ngā panera pouaka whakamātao, i te whakamahana paipa, me ngā pūnaha tuanui.
Huka Pūtau-Tuwhera
Pahuka pūtau-tuwhera, i tētahi atu ringa, he ngāwari ake, he māmā ake te hanganga, kei reira ngā pūtau e tuwhera ana, e āhei ai te hau ki te whakakī i ngā āputa i waenganui i ngā pūtau. He ngohengohe ake tēnei pahuka, ā, he iti ake te matotoru i te pahuka pūtau-kati.
Kiato: Ko te mātotoru o te pahuka pūtau-tuwhera he 0.5 lbs/ft3, kia māmā ake ai, kia ngāwari ake ai hoki.
Ārai Wera: He iti ake te uara-R, tata ki te 3.5 ki te 4 ia inihi, engari he pai tonu te ārai wera. He maha ake te whakamahinga i roto i ngā tono o roto kāore he take nui o te ātete ki te makuku.
Ārai oro: Nā tōna hanganga tuwhera, he tino pai ngā āhuatanga mimiti oro o te pahuka pūtau-tuwhera, ā, he pai mō te ārai i te oro o ngā pakitara me ngā tuanui o roto.
Te mimiti makuku: He rerekē te pahuka pūtau-katia, ka taea e te pahuka pūtau-tuwhera te mimiti i te makuku, ā, kāore i te pai mō ngā wāhi he nui te haumākū.
Ngā Whakamahinga:He mea whakamahi noa mō ngā mahi ārai haruru, te whakamahana whare, me ngā urunga whakapaipai o roto.
Te Tūranga oNgā Whakakōkī Polyurethanei roto i te Hanga Pahuka
He wāhanga matua ngā whakakorikori polyurethane mō te hanga pahuka pūtau-katia me ngā pahuka pūtau-tuwhera. Ko ēnei whakakorikori te kawenga mō te whakahaere i ngā tauhohenga matū i waenga i ngā polyol me ngā isocyanate i te wā o te tukanga hanga pahuka. Ki te kore he whakakorikori, ka puhoi, ka kore hoki e whai hua ēnei tauhohenga, ka hua ake he pahuka kounga-kore. Ko te whiriwhiri i te whakakorikori ka pā tika ki ngā āhuatanga o te pahuka pēnei i te mātotoru, te hanganga pūtau, te wā piki, me te tere o te whakaora.
Anei te mahi a ngā whakakorikori polyurethane me tōna pānga ki te hanga pahuka:
1. Te Whakataurite i te Tauhohenga i waenganui i ngā Polyol me ngā Isocyanates
I roto i te hanga pahuka polyurethane, ka āwhina ngā whakakorikori ki te whakahaere i ngā tauhohenga matua e rua: tetauhohenga whakapūkarame tetauhohenga pupuhiKo te tauhohenga whakapūpū e pā ana ki te hanganga o te hanganga pūmua, ko te tauhohenga pupuhi ia e whakaputa ana i te hau e whakawhanui ana i te pahuka.
Ka taea te whakarōpū i ngā whakakōkī polyurethane kingā whakakorikori aminemengā whakakorikori whakarewa, e rua ngā mahi e whai wāhi ana:
Ngā Whakakōkī AmineKo ēnei whakakorikori, pērā iMXC-37 (DMAEE)meMXC-A1 (BDMAEE), whakatairanga i tetauhohenga pupuhi, e āwhina ana ki te whakahaere i te hanganga pūtau o te pahuka. He mea tino nui tēnei i roto i te hanga pahuka pūtau-tuwhera, me hanga e te whakakorikori he hanganga hauhautanga, ngāwari hoki.
Ngā Whakakōkī Konganuku: Dibutyltin dilaurate (MXC-T12)hei tauira, e whakatairanga ana i tetauhohenga whakapūkara, e ārahi ana ki te hanganga o tētahi hanganga pakari, mārō. I roto i te hanga pahuka pūtau-katia, he mea nui ēnei whakakorikori hei whakatutuki i te hanganga pumau o te pahuka.
2. Te Whakapai Ake i te Kiato me te Kaha o te Pahuka
He mahi nui tā te pūnaha whakakorikori i roto i te tautuhi i tematotorumekahao te pahuka. Mō te pahuka pūtau-kati, mā te whakakorikori tika ka mau te pahuka i te kaha me te pakari e tika ana hei tu atu i te ahotea miihini, engari mō te pahuka pūtau-tuwhera, ka āwhina te whakakorikori ki te pupuri i te hanganga ngawari ake, ngāwari ake. Ko ngā whakakorikori pēnei iMXC-15 (pāhare pākawa oktanoate)he tino whai hua ki te arotau i te kiato o te pahuka me te whakarite kia ōrite te tohatoha o ngā pūtau, he mea nui tēnei mō ngā rauemi whakamarumaru mahi teitei.
3. Te Whakahaere i te Wā Whakaara me te Tere Whakamaroke
I roto i ngā whakamahinga pahuka polyurethane rehu (SPF), he mea nui te whakahaere i te wā piki me te tere whakamaroke kia pai ai te whakamahinga me te hua whakamutunga pumau. Ko ngā matū whakakorikori pēnei i teMXC-T(he whakakorikori tine rite ki te T) rāneiMXC-R70(2-(2-dimethylaminoethoxy)ethanol)kua hangaia hei whakarato i ngā wā whakamaroke tere me ngā tauhohenga taurite, kia taea ai te tono pahuka i te wāhi. Ko te tikanga o te whakamaroke tere he poto ake ngā wā kore-piri me te kaha ki te tono tere i ngā paparanga maha, he mea nui tēnei i roto i ngā tono SPF nui.
4. Te Whakaiti i ngā Tukunga me te Kakara
I roto i te hanga pahuka o ēnei rā, he mea nui ngā whakaaro mō te taiao, ā, kua noho ko te whakaiti i ngā tukunga me ngā kakara mai i ngā whakakorikori hei kaupapa matua. Ko ngā whakakorikori kakara iti, iti te tukunga pērā iMXC-R40meMXC-TMAkua hangaia kia tutuki ai ngā ture taiao pakari, me te pupuri tonu i te whai huatanga whakaterenga teitei. He mea nui ēnei whakaterenga i roto i ngā tono whakamahana o roto, ina raru pea te noho mai o ngā kakara kaha, ngā tukunga rānei.
Te Kōwhiri i te Whakakōkī Polyurethane Tika mō āu Whakamahinga Pahuka
He mea nui te whiriwhiri i te whakakorikori polyurethane tika hei whakatutuki i ngā āhuatanga e hiahiatia ana o te pahuka. Ko ngā mea hei whakaaroaro ko:
Momo pahukaPahuka pūtau-katia, hukaka pūtau-tuwhera rānei.
TonoTe ārai i te hau, te ārai haruru, te tuanui, te urunga rānei.
Ngā whakaaro mō te taiaoHe iti ngā tukunga VOC, he iti te haunga, ā, he tutuki i ngā ture taiao.
Ngā whakaritenga whakaoraNgā wā whakamaroke tere, puhoi rānei i runga i te tukanga whakaputa.
