Kua noho ngā paninga polyurethane hei tētahi o ngā pūnaha paninga tiaki me te whakapaipai e whakamahia whānuitia ana puta noa i ngā ahumahi, mai i ngā motuka me te hanga ki ngā taonga whare, ngā papa, me ngā hikohiko. Ko tō rātou rongonuitanga e akiakihia ana e te roa o te mau, te ātete matū, te piri, me te ātete ki te huarere. Ko tētahi mea nui kei muri i ēnei painga mahi ko te whakamahinga ongā whakakorikori polyurethane, e whakahaere ana, e whakateretere ana hoki i ngā tauhohenga matū i te wā e hangaia ana me te whakamaroke ana te paninga.
I roto i tēnei tuhinga, ka tūhuratia e mātou ngāNgā mātāpono tono o ngā whakakorikori polyurethane i roto i te umanga paninga, e whakaatu ana i ā rātou mahi, ngā paearu kōwhiringa, me te pānga ki te mahi.
1. Te Tūranga oNgā Whakakōkī Polyurethanei roto i ngā paninga
Ka hangaia ngā paninga polyurethane mā te tauhohenga i waenga i ngā polyol me ngā isocyanate, i te nuinga o te wā i te aroaro o ngā tāpiringa pēnei i ngā whakarewa, ngā whakakī, ngā tae, me ngā kaihoko whakamaroke. Ki te kore he whakakorikori, ka puhoi te haere o tēnei tauhohenga, ka mutu ka kore e oti te whakamaroke, ka ngoikore te hanganga kiriata, ā, ka ngoikore hoki ngā āhuatanga miihini.
Ngā whakakorikori polyurethanehe tūranga matua tēnei e whai wāhi ana ki:
- Te whakahaere i ngā tere tauhohengaTe whakarite i te taurite i waenga i te roa o te wā mahi (te roa o te kohua) me te tere o te whakamaroke.
- Te whakatairanga i te ōritetanga o te kiriataHei āwhina i te whakatutuki i ngā whakaotinga mata maeneene me te mārō pumau.
- Te whakapakari i te piriTe whakapai ake i te hononga i waenga i te paninga me te papa.
- Te whakapai ake i ngā āhuatanga āteteTe whakanui ake i te ātete ki ngā matū, te pakū, me te huarere.
I te poto, ka whakarite te whakakorikori kia tutuki i ngā paninga polyurethane tā rātou mahi kua hoahoatia, me te pupuri tonu i te whai huatanga i roto i te whakaputanga ahumahi.
2. Ngā momo Whakakōkī Polyurethane mō ngā Paninga
E rua ngā momo matua o ngā whakakorikori e whakamahia ana e te umanga paninga:
- Ngā Whakakōkī Amine
- Whakatereterehia ngā tauhohenga urethane (polyol–isocyanate) me te urea (isocyanate–wai).
- Whakaratohia te ngāwari ki te whakahaere i te tere whakamaroke me te hanganga kiriata.
- Ko ētahi tauira ko ngā amine tuatoru pērā i te BDMA, te DMEA, me te BDMAEE.
- Ngā Whakakōkī Konganuku
- Ko ngā matū organotin te tikanga pērā ite dibutyltin dilaurate (DBTDL).
- Ka whakarato i te mahi whakapūkara kaha, kia mārō ai, kia kaha ai hoki te mahi ā-ringa.
- E whakamahia ana i roto i ngā paninga polyurethane mahi-teitei e hiahia ana kia tere te wā e kore e piri.
He maha ngā wā,he huinga o ngā whakakorikori amine me ngā whakakorikori konganukuhei whakataurite i te whakaroa o te pito o mua me te whakamaroke o te pito o muri, kia pai ai te mahi me te mahinga whakamutunga o ngā paninga.
3. Ngā Mātāpono Whakamahinga i roto i te Ahumahi Paninga
I te whakamahi i ngā whakakorikori polyurethane ki ngā paninga, me whai whakaaro ngā kaihanga ki ngā mātāpono e whai ake nei:
- Taurite i waenga i te roa o te kohua me te tere o te whakamaroke:
Me roa te whakamahinga o te paninga hei paninga, engari me tere te whakamaroke i muri i te paninga. Ko te whiriwhiri i te momo whakakōkī tika me te horopeta te mea nui hei whakatutuki i tēnei taurite. - Te whakahaere i te pakeke me te ngāwari o te kiriata:
Ko ngā whakakōkī whakarewa te tikanga ka whakanui ake i te pakeke me te ātete ki te pakū, ko ngā whakakōkī amine ia ka whakarato i te ngāwari. Ko te ōwehenga o ēnei whakakōkī te mea e whakatau ana i ngā āhuatanga o te kiriata whakamutunga. - Te tutuki i ngā whakaritenga taiao me ngā ture:
I te mea kua piki haere ngā here ki ngā VOC me ngā konganuku taumaha, kei te piki haere te rongonui o ngā whakakorikori amine iti-kakara me ngā whakakapinga kore-tine i roto i ngā whakatakotoranga paninga. - Hototahi ki ngā pūnaha whakatakotoranga:
Me hototahi ngā whakarewa ki ngā whakarewa, ngā tae, me ētahi atu tāpiringa hei karo i ngā raruraru pēnei i te kohu, te whakapūpū, te tae kē rānei. - Te arotautanga o te mahi mō te whakamahinga mutunga:
Mō ngā paninga ahumahi (hei tauira, ngā motuka, ngā papa), he mea nui te tere o te whakamaroke me te ātete ki ngā matū. Mō ngā paninga rakau, ngā peita whakapaipai rānei, ko te hanganga kiriata maeneene me te ngāwari pea te mea nui.
4. Ngā Painga o te Whakamahi i ngā Whakakōkī Polyurethane i roto i ngā Paninga
Mā te whakamahi i te pūnaha whakakorikori tika, ka taea e ngā kaihanga paninga te whakatutuki i:
- Ka tere ake te maroke, ka nui ake te hua.
- Kua pai ake te piri ki ngā mea whakarewa, kirihou, me te rakau.
- Te kaha ā-mīhini me te ātete ki te huarere kua whakanuia.
- He nui ake te ngāwari o te hoahoa i te hanga paninga mō ngā momo ahumahi rerekē.
E whakamārama ana ēnei painga he ahangā whakakorikori polyurethane i roto i ngā paningahe mea nui kia tutuki ai te kounga pumau me te whakatutuki i ngā hiahia o ngā kiritaki i roto i ngā tono kanorau.
