Tikanga Whakapūngao Chromium I roto i ngā tukanga whakarite maha, ko te hanga o te hydroxypropyl acrylate hpa mā te whakamahi i ngā whakapūngao chromium he huarahi tukanga tuku iho. Ko ngā whakapūngao chromium kei roto ko te chromium trichloride, te chromium trioxide, me te chromium acetate. He nui te kaha whakapūngao engari he uaua ki te whakarite, ā, he morearea te tukanga. He maha ngā wā ka whakamahia ngā whakapūngao chromium me ngā tāpiringa whakapūngao me ngā aukati polymerization i te wā e whakamahia ana. Ina koa, he kaha te chromium trioxide ki te waikura me ngā āhuatanga whakapūngao tino kaha me te waikura, ka tino morearea te rokiroki me te kawe. Nā te mea he konganuku taumaha te chromium, he pānga teratogenic me te carcinogenic. Heoi anō, i muri i te purenga hua, ka noho te nuinga ki roto i te wai toenga, he matotoru teitei, ā, ka uaua te whakaora me te maimoatanga o te chromium acetate. Ko te whakawhanaketanga o ngā whakapūngao me ngā tukanga matomato, haumaru, me te taiao-hoahoa kua noho hei wāhi rangahau i roto i te ao mātauranga.

Wetekina te auahatanga me te Hydroxypropyl Acrylate HPA: He piri pai rawa atu, he kaha honohono, me te hototahi hei kawe i ō hua ki te taumata e whai ake nei!
