Hei kaiwhakarato matua mō ngā whakakorikori polyurethane, e harikoa ana mātou ki te whakapuaki i te tūranga nui o ēnei whakakorikori i roto i te hanga pahuka polyurethane, he rauemi maha-whakamahinga e whakamahia ana i roto i ngā momo ahumahi. Ko ā mātou hua, tae atu ki te MXC-A33, MXC-T me te maha atu o ngā whakakorikori motuhake, he wāhanga nui o te tukanga hanga pahuka polyurethane, e whakarite ana i ngā tauhohenga whai hua me ngā hua mahi teitei.
Te Hanganga o te Pahuka Polyurethane
Ka puta te pahuka polyurethane mā te tauhohenga matū i waenga i ngā diisocyanates me ngā polyols, e rua i ahu mai i te hinu mata, ahakoa ka taea hoki te hanga polyols mai i ngā hinu taiao hou. Ka hua ake i tēnei tauhohenga he mekameka polymer e hanga ana i te hanganga matua o te pahuka. E ono ngā wāhanga matua o te hanga pahuka polyurethane:
- Ngā PolyolKo te poraka hanga matua o te pahuka, e tauhohe ana ki ngā diisocyanates.
- Ngā DiisocyanateNgā matū matua e hono ana ki ngā polyol hei hanga i te pahuka.
- Ngā kaihoko pahukaKa āwhina ēnei ki te hanga i te hanganga pūtau o te pahuka.
- Ngā matū horoiWhakapūmautia te pahuka i te wā e whakawhanui ana.
- Ngā WhakakōkīWhakateretere ake i te tauhohenga i waenga i ngā polyol me ngā diisocyanates, kia pai ai te hanganga o te pahuka.
- Ngā WhakamārōE whakamahia ana ngā hononga whakawhiti me ngā mekameka whakaroa hei whakarei ake i te pakari me te mahi a te pahuka.
Ina whakakotahihia ēnei kai, ka tauhohe matū, ka puta he wera, he hau, me te hanganga āhua o te pahuka. Mā ngā matū whakakorikori pēnei i a mātou MXC-A33 me MXC-T ka āwhina i tēnei tauhohenga, ka whakarite kia whakahaeretia, kia whai hua hoki te tukanga.
Ngā Whakamahinga Whakakōkī i roto i te Pahuka Polyurethane
E rua ngā momo matua o te pahuka polyurethane: he pakari, he ngāwari hoki. Kei roto i ngā whakamahinga ko te whakamahana i roto i te hanganga (huka pakari) ki te whakamarumaru i roto i ngā tāonga me ngā roto o te motuka (huka ngāwari). Kua whakaritea ā mātou whakakorikori kia rite ki ngā hiahia maha:
-MXC-A33:He whakakorikori i hangaia mai i te 33%TEDA (triphenylenediamine) me te 67%DPG (monoconjugated dipropylene glycol), i hangaia mō ngā pahuka polyurethane me ngā elastomers polyurethane. He whānuitia te whakamahinga i roto i te pahuka polyurethane ngohengohe, āhua-pakari, pakari, paninga, elastomer.
-MXC-T:He matū whakakorikori amine whai hua, kāore he tukunga, e whakarato ana i te pihi tauhohenga maeneene, ā, ka taea te whakamahi hei whakaputa i ngā momo pahuka polyurethane. Ko tana mahi whakakorikori ka whakatairanga i te tauhohenga o te urea (wai-isocyanate), e ngāwari ana ki te tauhohe ki te hanganga polymer nā tōna rōpū hydroxyl hohe. Mō tēnei take, ka whakamahia te TMAEA hei rehu i te whakamahana pahuka, ngā papaaho motuka, me ētahi atu wāhi e hiahia ana kia iti te kakara toenga..
Mā ngā whakakorikori polyurethane ka tika te tere o te tauhohenga, ka whakatikatika i ngā āhuatanga pahuka pērā i te mātotoru, te pakeke, me te hanganga. Mā tēnei tino tika ka taea e te pahuka polyurethane te whakatutuki i ngā tono uaua o ngā ahumahi hou, tae atu ki te hanga, te motuka, te tāonga whare, me te takai.
Mō Mātou
He kaiwhakarato matua mātou mō ngā whakakorikori polyurethane mahi-teitei, e whakapau kaha ana ki te whakarato i ngā otinga auaha mō ngā tono ahumahi kanorau. Mā tā mātou raina hua whānui ka āwhina i ngā kaihanga ki te arotau i ngā tukanga whakaputa pahuka me te whakatutuki i ngā paerewa taiao me ngā paerewa ture.
