Kupu Whakataki
I ngā tau tata nei,ngā whakakorikori polyurethane kakara iti kua noho hei ia whanaketanga i roto i te umanga polyurethane. I te mea kei te piki haere te kaha o ngā paerewa taiao o te ao, me te piki haere o te hiahia o ngā kiritaki mō ngā taiao o roto ma, ko te ia whanaketanga ongā whakakorikori polyurethane iti-tukunga, iti-kakara kei te tere haere. Ko ngā kaihanga o ngā pahuka ngāwari me ngā pahuka pakari, ngā paninga, ngā piripiri, me ngā hiri kei te whakatairanga i ngā whakakorikori e whakakotahi ana mahi teitei, VOC itis, mete atawhai i te taiao me te kore e whakararu i te tauhohenga.
He aha te Hiranga o te Kakara i roto i te Hanga Polyurethane
Ahakoa he tino whai hua ngā whakakorikori amine tuku iho ki te whakatairanga i te tauhohenga polyurethane i waenga i ngā isocyanates me ngā polyols, he maha ngā wā ka tukuna ngā amine pūngoi i te wā e hangaia ana, e whakamarokehia ana rānei. Ka taea e ēnei tukunga te arahi ki:
Skakara amine kahas i roto i ngā hua kua oti (pērā i ngā pahuka me ngā paninga)
rotongā raruraru kounga hau
Mahingā take mō te pānga o te r me te tutuki i ngā ture
Hei whakatutuki i ngā hiahia hauora me te taiao o nāianei, kei te tere haere ngā ahumahi ki tengā pūnaha whakakorikori iti-kakara, iti-te-whakakorikoriKa whakaitihia e ēnei whakakorikori ngā tukunga me te pupuri tonu i te mahi pahuka me te whakamaroke tino pai.
Te Putanga Ake o ngā Whakakōkī Amine Kakara Iti
Kua hangaia ngā whakakorikori polyurethane kakara iti heiwhakaitihia te pōturitanga me te whakapai ake i te whiriwhiringaMā te whakarerekē i tō rātou hanganga ngota, mā te whakauru rānei i ngā rōpū mahi tauhohe, ka taea e ēnei whakakorikori te hono matū ki te anga polyurethane, ā, mā reira ka ārai i te mimiti haere o ngā matū e whakaputa ana i te kakara.
Ko ngā hangarau matua i tēnei mara ko:
Ngā whakakorikori amine tauhohee hono tahi ana ki te pūmua
Ngā whakakōkī amine kua āraiame te tukunga whakahaere i te wā o te tauhohenga
Ngā pūnaha amine tuatoru iti-tukungame te pumau hydrolytic kua whakarei ake
Hei tauira, ko ngā whakakorikori pēnei i a Mingxu New Materials'MXC-R40 meMXC-37 he mea hanga motuhake hei whakaatuiti te kakara, teitei te tauhohenga, me ngā āhuatanga huka-kiri taurite. He whānuitia te whakamahinga i roto ipahuka rehu pakari, ngā rauemi whakamahana taputapu, pahuka o roto o te motuka, me Ngā pūnaha HFO.
Ngā Ārahi Taiao me ngā Ture
He maha ngā āhuatanga o te ao e tere ake ana te whakauru ingā whakakorikori polyurethane kakara iti:
Kei te piki haerengā ture pakari mō te VOC (pūhui waro mimiti) me ngā tukunga i Ūropi, Amerika Te Raki, me Āhia.
Ngā tiwhikete oranga tonutanga (LEED, BREEAM, GREENGUARD) kei te akiaki i te whakamahinga o ngā rauemi ma.
Te hiahia o te kaihoko Kei te piki haere te utu mō ngā tāonga whare, ngā moenga, me ngā roto o ngā motuka he iti te tukunga.
Te nekehanga ahumahi ki te HFO me ngā pūnaha pahuka wai, e hiahia ana ki ngā whakakorikori whiriwhiri ake.
Ngā kaihanga e whakamahi anangā hangarau whakakorikori iti-tukunga ehara i te mea e tutuki ana i ngā whakaritenga ture anake engari e whakarei ake ana hoki i te uara waitohu me te whiwhi painga whakataetae i ngā mākete kaweake.
Ngā Painga o te Whakamahi i ngā Whakakōkī Polyurethane Kakara Iti
Te whakatinanatangangā whakakorikori kakara itiHe maha ngā painga o te hanga polyurethane:
Te whakaiti i te kakara i roto i ngā hua pahuka kua oti
Te whakapai ake i te haumaru o ngā kaimahi me te taiao o te tipu
He pai ake te kounga o te hau o roto mō ngā kaiwhakamahi mutunga
Te tutuki i ngā paerewa tukunga VOC
Te tauhohenga pumau me ngā kōtaha pikinga pahuka ōrite
Mā ēnei painga kangā whakakorikori polyurethane kakara iti he whiringa whānuitia mō ngā kaihanga pahuka puta noa i te ao.
Ngā Taupānga puta noa i ngā Pūnaha Polyurethane
Kei te whakamahia ngā whakakorikori haunga iti i roto i te nuinga o ngā pūnaha polyurethane:
Ngā pahuka ngāwari: nohoanga motuka, urunga tāonga, moenga
Ngā pahuka pakari: ngā panera whakamahana, ngā pahuka rehu, ngā pahuka pouaka whakamātao
Ngā paninga, ngā piripiri, ngā hiri, me ngā elastomers (CASE): e hiahia ana kia kore e kōwhai, kia iti te tukunga
Ina koa,Te whakamahana pahuka rehu HFOKa whai hua ngā pūnaha i ngā whakakorikori iti-kakara e pupuri ana i te kaha teitei me te ārai i ngā haunga amine kāore e hiahiatia i roto i ngā taiao hangahanga kuiti.
Whakamutunga
Te ia kingā whakakorikori polyurethane kakara iti ehara i te mea ko te urupare ki ngā ture anake engari ko te whanaketanga o te umanga ki te pumau, te haumaru, me te whakapai ake i te kounga. Mā te tango i ngā mea matatau ngā hangarau whakakorikori iti-tukunga, ka taea e ngā kaihanga polyurethane te whakatutuki i te hanga ma, ngā rauemi pahuka mahi teitei ake, me te whakanui ake i te makona o ngā kaiwhakamahi mutunga.
Hei tētahi o ngā kaiwhakarato matua o Haina mō ngā whakakorikori polyurethane,Ngā Rauemi Hou a Mingxu whakawhanake tonu i ngā mahi auahangā whakakorikori iti-kakara, mahi teitei hei whakatutuki i ngā hiahia o ngā pūnaha pahuka hou. Kei roto i tā mātou kohinga huaMXC-R40, MXC-37, me MXC-DPA, e whakarato ana i ngā otinga tino pai mō ngā kiritaki e rapu ana i te taurite i waenga i te tauhohenga, te pumau, me te kawenga mō te taiao.
