I roto i te umanga polyurethane o te ao,He mahi nui tā ngā whakakorikorii roto i te whakateretere i ngā tauhohenga, te arotau i ngā āhuatanga pahuka, me te whakarei ake i te pai o te whakaputa. I te mea kei te horapa tonu te polyurethane puta noa i ngā ahumahi pēnei i te whakamahana, te motuka, te tāonga whare, te hu, me te hanga, ko te hiahia mō te mahi teiteingā whakakorikori polyurethanekua tino piki ake. Te mārama ki tengā au whanaketanga me te ahunga whakamua hangarauhe mea nui tēnei mahi mō ngā kaihanga e hiahia ana kia noho whakamua i roto i te mākete whakataetae.
1. Ngā Whakakōkī Polyurethane:He Kōhatu Matua mō te Hanga Pahuka
Ka hangaia te polyurethane mā te tauhohenga o ngā polyol me ngā isocyanates, he tukanga e tino whakawhirinaki ana ki ngā whakakorikori. Ko ēnei whakakorikori—ko te nuinga he amine-based me te konganuku-based—ka whakahaere i tengā tauhohenga pupuhi (huka) me te whakamaroke (whakapūmau), kia rite ai te kounga o te hua, te kaha ā-ringa, me te hanganga pahuka e hiahiatia ana.
He maha ngā momo whakakorikori e whakamahia ana i roto i ngā pūnaha polyurethane:
- Ngā amine tuatoru:Whakatairangahia te tauhohenga pupuhi me/te tauhohenga whakapiripiri rānei.
- Ngā whakakorikori whakarewa(pērā i ngā matū tine, pāhare pākawa, bismuth rānei): Whakateretere ake i te tukanga whakamaroke me te whakapai ake i ngā āhuatanga whakamutunga.
- Ngā whakakorikori iti-tukunga me te tauhohengaI whakawhanakehia hei whakautu i ngā ture taiao.
2. Ngā Auahatanga Whakawhanake Ahumahi
a. Ngā Whakaritenga Taiao me ngā Whakatakotoranga Tukunga Iti
Mā te whakakaha ake i ngā ture taiao pēnei i teREACH i Ūropi, TSCA i te US, me ngā kaupapa whakaiti VOC o te ao, kei te neke haere ngā kaihanga whakakorikori polyurethane kihe iti te tukunga, kāore e paitini, ā, he tauhohe hoki ngā whakatakotoranga whakakōkī.Kei te piki haere te whakakapinga o ngā whakakōkī amine tuku iho he tine, he kakara nui rānei, e:
- Ngā whakakorikori amine tauhoheka herea matū ki roto i te anga polyurethane.
- Ngā kōwhiringa iti-VOCe whakaiti ana i ngā tukunga i te wā e whakaputa ana me te whakamahi i ngā hua.
- Ngā whakakorikori konganuku kore-taumaha(hei tauira, te bismuth, te konutea rānei) hei whakakapi i te dibutyltin dilaurate (DBTDL).
Ka aro atu tā mātou kohinga hua ki tēnei ia au me ngā otinga pēnei iMXC-B20,MXC-R40,meMXC-T12,e whakarato ana i te tauhohenga tino pai me te tutuki i ngā paerewa taiao me te haumaru o te ao.
b. Hototahi ki te Ākena Pupuhi HFO
I te whakakorenga o ngā kai pupuhi GWP-tiketike, pērā i te HFC-245fa, kua whānuitia te whakamahi a te umangaNgā pūnaha e hangai ana ki te HFO(hei tauira, HFO-1233zd). Me whakamahi ēnei pūnaha i ngā whakakorikori kua whakatikatikaina kia mau tonu te taurite i waenga i te tere o te tauhohenga me te mahi pahuka. Ko ā mātou whakakorikori hototahi ki te HFO, pērā iMXC-MB20meMXC-70, he mea hanga motuhake hei whakarato i ngā kōtaha piki maeneene me te whakamaroke mata pai rawa atu i roto i ngā pūnaha HFO, e whakamahia whānuitia ana i roto ipahuka rehu, papa rakau mārō,mewhakamahana taputapu.
c. Ngā Taupānga Mahi-Tiketike
Ko ngā tono polyurethane hou e hiahia ana kia nui atu i te mahi pahuka taketake. Ko ngā nohoanga motuka, ngā kapu hu, ngā pahuka kiri whakauru, me te whakamarumaru whare e penapena ana i te pūngao e hiahia ana ki ngā whakakorikori e tuku ana i:
- Te whakaroa i te tauhohenga mō te whakakī pai ake i te pokepokea ai
- Ngā kōtaha whakaora kua whakapaitia
- Ngā āhuatanga hangarau whakarei ake
- Hototahi ki ngā pūnaha matotoru-teitei
Ngā hua pēnei iMXC-37meMXC-54hei tautoko i ēnei mākete mā te whakarite kia tino pai te rere o te kirīmi, kia roa ake te wā e whakamarokehia ai, kia whai hua ai hoki te whakamaroke i te pito o muri.
3. Ngā Whakatairanga Hangarau i roto i te Hanganga Whakakōkī
Ko ngā putanga hou o te hangarau whakakorikori ko:
- Ngā whakakorikori maha-mahi:Whakakotahitia te pahuka, te whakamaroke, me te whakatairanga i te piri o te mata ki roto i te ngota kotahi.
- Ngā pūnaha whakakorikori tahi:He ranunga o ngā whakakōkī amine me ngā whakakōkī konganuku hei whakahaere tika i ngā kōtaha tauhohenga.
- Ngā whakatakotoranga pumau:Kei te rangahauhia ngā whakakorikori e ahu mai ana i te koiora, i ngā pūtake hou rānei, mō ngā pūnaha PU matomato ake.
Hei kaihanga whakakorikori polyurethane, ka haumi mātou kiR\&D hei whakawhanake i ngā otinga ritengae tutuki ana i ngā hiahia e whanake haere ana mō te mahi, te taiao, me ngā ture. Ā mātouMXC-TMA,hei tauira, ka taea te whakahaere i te trimerization i roto i ngā pūnaha pahuka polyisocyanurate (PIR) e whakamahia ana i roto i ngā panera hanawiti me te whakamarumaru pāmahana-tiketike.
4. Tirohanga ki te Mākete o te Ao
E matapaetia ana ka tipu te mākete whakakorikori polyurethane o te ao i teCAGR neke atu i te 5% tae noa ki te tau 2030, e arahina ana e:
