MOKA,e mōhiotia ana ko te 4,4′-Methylenebis(2-chloroaniline), he tioata ngira ma ki te kōwhai mārama ka huri hei mangu ina werahia. He paku hygroscopic tēnei matū maha-whakamahinga, ā, ka wairewa i roto i ngā ketone me ngā hauwaiwaro kakara. Engari ko te mea e wehewehe ana i te MOCA ko tōna whānuitanga o ngā tono me ngā āhuatanga hua.
Ngā āhuatanga matū:He karaihe ngira wetekina, he mā ki te kōwhai mārama, he mea whakamahana kia pango. He paku waikura. Ka wairewa i roto i ngā ketone me ngā hauwaiwaro kakara.
Ko te MOCA te mea e whakamahia nuitia ana hei whakapūkara mō te rapa polyurethane whakarewa. Nā ōna āhuatanga honohono, he mea pai rawa atu tēnei hei whakarei ake i te kaha me te roa o ngā rauemi rapa. Hei tāpiri, he mea honohono te MOCA mō ngā paninga polyurethane me ngā piripiri, e pai ake ai te piri me te mahi. Hei tāpiri, ka taea te whakamahi i tēnei matū hei whakaora i ngā kapia epoxy, ā, he mea nui tēnei i roto i ngā momo ahumahi.
Heoi anō, ka taea te whakamahi i te MOCA ki ōna āhua rerekē. Ka taea te whakamahi i te MOCA wai hei rongoā polyurethane i te pāmahana rūma, he mea ngāwari, he mea ngāwari hoki te whakamahi. Ka taea hoki te whakamahi hei rongoā polyurethane mō te rehu, hei whakawhānui ake i tōna whānuitanga o te whakamahinga.
Ngā Painga me ngā Tono：
Ina tae ki te ao o te rapa polyurethane me ngā paninga, he mea tino nui te kimi i te kaihopu whakamomona me te kaihopu whakawhiti tika. Koinei te wāhi e noho matua ai te MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)). Nā ōna āhuatanga tino pai me te whānuitanga o ngā tono, kua noho te MOCA hei mea nui i roto i ngā momo ahumahi.
E mōhiotia ana te MOCA mō tōna āhua he karaihe ngira ma ki te kōwhai mārama, ka huri hei mangu ina pāngia e te wera. Hei tāpiri, he āhua waikura iti tōna, ā, ka wairewa ki ngā ketone me ngā hauwaiwaro kakara. Nā ēnei āhuatanga he mea pai mō te whakamahi i roto i ngā tukanga hanga rerekē.
Ko tētahi o ngā painga matua o te MOCA ko tōna tūranga hei kaiwhakapūkara mō te rapa polyurethane whakarewa. Mā te hono i ngā mekameka polymer, ka whakarei ake te MOCA i te kaha me te pakari o te rapa. Mā tēnei ka taea e te hua whakamutunga te tu atu ki ngā āhuatanga uaua me te pupuri i tōna āhua pai mō te wā roa.
Hei tāpiritanga, he pai rawa atu te MOCA hei hononga whakawhiti mō ngā paninga polyurethane me ngā piripiri. Ka whakatairanga i te hononga matū i waenga i ngā ngota polymer, ka hua ake he paninga me ngā piripiri e whakaatu ana i te mahi tino pai. Ahakoa mō ngā paninga tiaki, mō ngā piripiri hanganga rānei, ka whakaratohia e te MOCA te kaha me te pumau e tika ana.
Haunga ōna whakamahinga i roto i te rapa me ngā paninga, ka taea hoki te whakamahi i te MOCA hei whakaora i ngā kapia epoxy. Mā te tāpiri i ētahi iti o te MOCA, ka taea e te kapia epoxy te pā ki tētahi tauhohenga hononga whakawhiti, ka pai ake ai ngā āhuatanga miihini me te wera. Nā tēnei ka waiho te MOCA hei taputapu whai hua mō ngā ahumahi e whakawhirinaki ana ki ngā kapia epoxy mō ā rātou hua me ā rātou whakamahinga.
Hei tāpiritanga, kei reira tētahi momo wai o te MOCA e mōhiotia ana ko Moka. Ka taea te whakamahi i tēnei momo hei rongoā polyurethane i te pāmahana rūma, ā, he tino watea mō ngā tukanga whakaputa. Hei tāpiritanga, ka taea e Moka te mahi hei rongoā polyurethane mō ngā tono rehu. Nā tōna maha o ngā whakamahinga me te ngāwari o te whakamahi, he mea rongonui i waenga i ngā kaihanga.
Te tākai me te rokiroki：
Tākai:50kg/PAHU
Rokiroki：me waiho ki te wāhi matao, maroke, me te hauhautanga.
Te pumau:Ka wera, ka mangu, ka paku makuku. Kāore he whakamātautau mate taipitopito i Haina, ā, kāore i te tino mōhiotia he paitini, he kino rānei tēnei hua. Me whakapakari te taputapu kia iti ake te pa ki te kiri me te manawa mai i te ara manawa, kia iti ake ai te kino ki te tinana tangata.
Whakarāpopototanga：
Hei whakarāpopototanga, he tino whai hua te MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) mō te whakapūkara me te hono whakawhiti. Nā te whānuitanga o ngā whakamahinga i roto i te umanga rapa polyurethane, paninga, me te whakapiripiri, he mea whiriwhiri tēnei mā ngā kaihanga. Nā tōna kaha ki te whakarei ake i te kaha, te roa, me te here matū, he tino mahi nui tā te MOCA ki te whakarite i te kounga me te mahi o ngā momo hua.
