Mātauranga Ahumahi: Ngā Whakamahinga Whakakōkī Polyurethane

He mahi nui tā te umanga whakakōkī polyurethane i roto i te hanga pahuka polyurethane, e āhei ai ngā kaihanga ki te whakatikatika i ngā tere tauhohenga, te pumau o te pahuka, me ngā āhuatanga o te hua whakamutunga. He mea nui ngā whakakōkī polyurethane ki te akiaki i ngā tauhohenga matū i waenga i ngā polyol me ngā isocyanate, kia mōhio ai ka hangaia ngā rauemi polyurethane, pērā i ngā pahuka ngāwari, ngā pahuka pakari, me ngā pahuka rehu, me ngā āhuatanga miihini me te wera e hiahiatia ana. Ko te kōwhiringa o ngā whakakōkī he pānga nui ki te whai huatanga, te kounga, me te āhua taiao o ngā pūnaha pahuka ka puta.

Ngā Momo Whakakōkī Polyurethane

Ka taea te wehewehe i ngā whakakorikori polyurethane ki ngā momo e rua:

1. Ngā Whakakōkī Amine
   E whakamahia whānuitia ana ngā whakakorikori amine i roto i te umanga pahuka polyurethane, inā koa i roto i ngā pahuka ngāwari, ngā hanganga moroiti, me ngā tono elastomer. Ka āwhina rātou ki te whakahaere i te taurite i waenga i ngā tauhohenga pupuhi me te whakakorikori. He tino pai ēnei whakakorikori mō ngā tono e hiahia ana kia tika te hanganga o ngā pore me te pakari ā-pūkaha.

   Tauira: MXC-RE13
   He whakakorikori i ahu mai i te amine te MXC-RE13, he maha ngā whakamahinga. E whakamahia ana i roto ipahuka ngāwari kua whakapūmauhia e te ester, he mea nui mō ngā tono e hiahia ana kia roa te mau me te whakamarie, pērā i ngā tāonga me ngā moenga. Ka whakamahia hoki te MXC-RE13 i roto ipahuka moroiti, he mama, he pakari hoki, e tika ana mō ngā mahi pēnei i ngā nohoanga motuka. Hei tāpiri, e whakamahia ana i roto ingā elastomer, e whakarato ana i te tino ngāwari me te pakari.

2. Ngā Whakakōkī Konganuku
   Engari, ka whakatairangahia e ngā whakakorikori whakarewa te whakapūhui (te whakapūhui) me te honohono (te whakamaroke) i roto i ngā pūnaha polyurethane. He maha ngā wā ka whakakapia e ēnei whakakorikori ngā pūnaha tine tuku iho, inā koa i ngā wā e hiahiatia ana e ngā ture taiao te whakaiti i ngā konganuku taumaha, pērā i te mercury, te mata, te dibutyltin rānei.

   Tauira: MXC-B20
   He whakakorikori whakarewa te MXC-B20, he huarahi pumau hei whakakapi i ngā whakakorikori tine tuku iho.kāore he mercury, he mata, he dibutyltin rānei i roto, e piki haere ana te hiranga i roto i te horopaki o ngā paerewa taiao pakari. Ngā whakaaturanga a MXC-B20iti te piki me te hekemeiti rawa te kakara, e whakarite ana i te haumaru o ngā kaimahi me te mahi a te hua. He whakakorikori tika mōngā pepa ngāwari, pahuka ngāwari matotoru, pahuka rehu, mepahuka pakariNā tōna hototahitanga ki te whānuitanga o ngā whakatakotoranga, he mea pai tēnei hei whiringa mō ngā tono e hiahia ana ki ngā āhuatanga mahi teitei me te hoa-taiao.

Ngā Āpure Whakamahinga o ngā Whakakōkī Polyurethane

He mea nui ngā whakakorikori polyurethane mō te hanga i ngā momo pahuka rerekē, he rerekē ngā whakamahinga o ia momo i roto i ngā ahumahi mai i te motuka ki te hanga:

1. Pahuka Ngāwari
   He rauemi ngohengohe, pakari hoki ngā pahuka polyurethane ngāwari, e whakamahia whānuitia ana mō ngā mahi whakaruruhau pērā i ngā tāonga whare, ngā moenga, me ngā nohoanga motuka. Ka whakamahia ngā whakakorikori amine pērā i te MXC-RE13 hei whakatikatika i te hanganga pūtau o te pahuka, hei whakarato i te whakamarie me te pakari pai rawa atu. Mā te noho mai o ngā mea whakaū e ahu mai ana i te ester ka roa te mahi, ahakoa i raro i te ahotea miihini.
2. Pahuka Mārō
   Ko ngā pahuka polyurethane pakari e tohuhia ana e ō rātou āhuatanga ārai wera me te pakari hanganga. He mea whakamahi noa i roto ihanganga(ngā panera whakamahana, ngā papa tuanui) mengā taputapu(ngā pouaka whakamātao, ngā pouaka tio). Ka whakarei ake ngā whakakorikori pēnei i te MXC-B20 i te tukanga whakamaroke o te pahuka, ka whakapai akeārai werame te pumau o te hanganga me te whakaiti i ngā tukunga e pā ana ki ngā whakakorikori whakarewa tuku iho.
3. Pahuka Rehu
   E whakamahia whānuitia ana ngā pahuka polyurethane rehu (SPF) i roto i ngā mahi hanga whare mō ngā mahi whakamahana me ngā mahi tuanui, e whakarato ana i te pai o te pūngao me te hiri hau. E whakamahia ana ngā whakakorikori amine me ngā whakakorikori konganuku hei whakahaere i te pikinga o te pahuka, te piri ki ngā papa, me te wā whakamaroke. Hei tauira, ka whakarei ake a MXC-B20 i ngā pūnaha SPF mā te whakatairanga i te whakamaroke tere me te kore e pā kino ki te taiao o ngā whakakorikori kei roto he konganuku taumaha.

Whakamutunga

He mea nui te umanga whakakorikori polyurethane ki te hanga i te mahi a ngā pūnaha pahuka polyurethane, ahakoa he pahuka ngāwari, he pahuka pakari, he pahuka rehu rānei. I te ahu whakamua o te umanga ki te oranga tonutanga, ko te whanaketanga oiti te tukunga, haunga iti, mekāore he konganuku taumahaKei te piki haere te hiranga o ngā whakakorikori pēnei i te MXC-B20. Mā ēnei auahatanga ka tutuki ngā whakaritenga ture i ngā hua polyurethane, me te tuku anō hoki i ngā āhuatanga mahi-teitei e tika ana mō ngā tono hou.
