Kupu Whakataki
I roto i te umanga motuka o ēnei rā,polyurethane (PU) He mea nui te mahi a ngā rauemi ki te whakatutuki i te hoahoa māmā, te whakarei ake i te whakamarie, me te whakapai ake i te pakari. Mai i ngā nohoanga motuka me ngā papaaho ki ngā pane me ngā pūnaha whakamarumaru oro, kei roto i ngā kokonga katoa o te waka ngā wāhanga polyurethane. Kei muri i te mahi pai o ēnei rauemi he matū matua e akiaki ana.—tewhakakorikori polyurethaneKa whakahaerehia e te whakakorikori polyurethane te tere tauhohenga i waenga i ngā isocyanates me ngā polyols, kia tutuki ai i ia tono motuka ngā āhuatanga ā-pūkaha me ngā āhuatanga ā-tinana e hiahiatia ana.
He aha ngāNgā Whakakōkī Polyurethane?
Ngā whakakorikori polyurethane he matū e whakateretere ana i te tauhohenga i waenga i ngā polyol me ngā isocyanate i te wā e hangaia ana te pahuka. Ki te kore he whakakorikori, ka puhoi rawa te tere tauhohenga polyurethane, ka kore rānei e taea te whakahaere mō te hanga ahumahi. Mā te whakarerekē i te momo me te nui o te whakakorikori, ka taea e ngā kaihanga te whakahaere tika i tete whakapūkara, te pahuka, me whakaora ngā tukanga hei whiwhi pahuka he pakeke, he ngāwari, he pumau hoki.
E rua ngā momo matua o ngā whakakōkī polyurethane e whakamahia ana i roto i te umanga motuka:
Ngā whakakorikori amine—e whakamahia ana hei whakatairanga i te tauhohenga huka (tauhohenga wai-isocyanate) me te whakataurite i te pihi piki o te pahuka me te hanganga pūtau. Hei tauira, ko ngā whakakorikori amine tuatoru pērā i te MXC-A1 (BDMAEE) me te MXC-37 ka hua ake he pikinga pahuka maeneene me te tohatoha pūtau ōrite.
Ngā whakakorikori whakarewa—ngā whakakorikori kei roto i te tine, pērā ite dibutyltin dilaurate (MXC-T12) meoctoate stannous, whakateretere i tetauhohenga whakapūkara (te tauhohenga polyol-isocyanate), nā reira ka tere ake te whakamaroke me te whakapai ake i te kaha miihini. I roto i ngā pūnaha taiao, he mea houngā whakakorikori konganuku kore-tine kei te piki haere te whakamahinga hei whakaiti i ngā tukunga me ngā paitini.
Ngā Whakamahinga Matua o ngā Whakakōkī Polyurethane i roto i te Motuka
1. Ngā Nohoanga me ngā Pane o te Waka
Ko te pahuka polyurethane ngāwari te rauemi whakaruruhau e whakamahia whānuitia ana i roto i ngā nohoanga motuka me ngā okiokinga pane. Ko ngā mea whakakorikori pēnei i teMXC-A33or MXC-BDMA āwhina ki te whakahaere i te mātotoru me te pakari o te pahuka, kia mau tonu ai te whakamarie me te pakari. He pai rawa atu te pūnaha whakakorikori tauritete rere wawe, te hanganga pūtau ōrite,me te whakaora pai o te pēhanga ngā āhuatanga, e whakamahia ana hei hanga nohoanga motuka ergonomic.
2. Ngā Papaaho me ngā Wira Urunga
Ko ngā pahuka polyurethane āhua-pakari me te moroiti e whakamahia whānuitia ana i roto i ngā papaaho me ngā wira urungi. Me whakakotahi ēnei rauemi i te ngāwari me te pumau o ngā āhuatanga. Ko ngā matū whakakorikori pēnei i teMXC-R70 meMXC-B20 e whakamahia ana hei whakahaere i te whakaroa o te matotoru o te pito o mua, me te whakarite hoki i te pakari o te pito o muri. Ko te hua o tēnei hemata pahuka maeneeneme piri pai rawa atu ki te papa, e whakarei ake ana i te āhua ataahua me te pa atu.
3. Mana Whakahaere NVH (Haruru, Wiri, me te Kaha)
He rauemi tino whai hua te pahuka polyurethane hei mimiti haruru me te whakaiti wiri, e whakamahia whānuitia ana i roto i ngā panera tatau, ngā panera tuanui, me te whakamahana papa. Ko ngā mea whakakorikori pēnei i teMXC-41me MXC-TMA kia tika te hanga pahuka me te hanganga pūtau ōrite, kia pai ake ai te mahi ārai haruru me te wera.
4. Ngā Paninga me ngā Piripiri Motuka
I roto i te mara o ngā paninga me ngā piripiri motuka, ko ngā whakakorikori polyurethane pēnei i teMXC-T9me MXC-T12 ka whakateretere i te hononga whakawhiti me te whakamaroke, ā, ka whakapai ake i te piri, te kanapa, me te ātete matū. Mā ngā hanganga whakakorikori tika ka tere ake te maroke o ngā paninga me te kaha pai o te piri o ngā piripiri puta noa i ngā āhuatanga pāmahana.
Ngā Mātāpono Mahi o ngā Whakakōkī Polyurethane i roto i te Hanganga Waka
E rua ngā tauhohenga matū matua o te hanganga polyurethane:
Tauhohenga Whakapūpū:I waenganui i te isocyanate me te polyol, e hanga ana i ngā hononga urethane me te whakarato i te kaha.
Tauhohenga Pupuhi:I waenganui i te isocyanate me te wai, ka puta te hauhā waro hei hanga pahuka.
A pūnaha whakaterenga tauriteMā te whakakotahitanga tika ka puta ēnei tauhohenga e rua i ngā tere whakahaere. Ka whakatairangahia e ngā whakakorikori amine te tauhohenga pupuhi, ko ngā whakakorikori whakarewa ia ka tere ake te whakakorikori. Mā te huinga tika ka taea e te pahuka te whakawhanui maeneene me te kore e hinga, me te whakamaroke hoki kia eke ki te mahi miihini teitei.
I roto i te hanga waka, ko ngā tawhā tukanga pēnei i tete pāmahana, te haumākū, me te ōwehenga whakaranuka aro turukihia kia pai ake ai te whai huatanga o te whakakorikori. Ko te whāinga kia tutuki ngā āhuatanga pahuka ōrite, kia iti ake ngā tukunga, kia pumau ai te mahi mō te wā roa.
Ngā Painga o te Whakamahi i ngā Whakakōkī Polyurethane Mahi-Tiketike
Mana Whakahaere Tika:Whakatikatikahia te wā pahuka me te wā whakamaroke mō ngā wāhanga rerekē o te motuka.
He iti te kakara me te tukunga:Ngā whakakorikori hou pērā iMXC-R40meMXC-70He iti te mahi VOC e tika ana mō ngā roto waka e pai ana ki te taiao.
Hototahi:E pā ana ki ngā mea e ruaHFCmeNgā pūnaha pupuhi HFO, e tautoko ana i ngā au whakangao tauwhiro.
Te Pumautanga Whakapai Ake:Whakarei ake i te ātete o te pahuka, te piri, me te ātete wera kia roa ake ai te ora o te wāhanga.
Whakamutunga
Ko ngā whakakorikori polyurethane ngā toa rongonui o muri i te whakamarie, te haumaru, me te pakari o ngā motuka hou. Mā te whakahaere i ngā tere tauhohenga me te hanganga pahuka, ka whakarite kia tutuki i ia nohoanga, i ia panera, me te paparanga whakamarumaru ngā paerewa motuka pakari. I te nekehanga o te umanga kihoahoa māmāme te hanga matomato, ka whai wāhi tonu ngā whakakorikori polyurethane mahi-teitei, iti-tukunga ki te whakatairanga i te auahatanga.
