Hoʻohana
He mea hoʻopaʻa māmā kēia huahana me ka hana maikaʻi, hiki ke omo i ka kukuna UV o ka nalu 240-340 nm me nā ʻano o ke kala māmā, ʻaʻohe ʻawahia, kūpono maikaʻi, neʻe liʻiliʻi, maʻalahi ka hana ʻana a pēlā aku. Hiki iā ia ke pale i ka polymer i kona nui loa, kōkua i ka hōʻemi ʻana i ke kala. Hiki iā ia ke hoʻopaneʻe i ka melemele a keakea i ka nalowale o kāna hana kino. Hoʻohana nui ʻia ia i ka PE, PVC, PP, PS, PC organic glass, polypropylene fiber, ethylene-vinyl acetate etc. Eia kekahi, he hopena maikaʻi loa kona kūpaʻa māmā i ka hoʻomaloʻo ʻana i ka phenol aldehyde, varnish o ka waiʻona a me ka acname, polyurethane, acrylate, expoxnamee etc.
