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 pāngia e te 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.
