ʻO ka photostabilizer UV770 he haʻahaʻa molecular haʻahaʻa haʻahaʻa i ka amine photostabilizer, nona nā hiʻohiʻona o ka hoʻohālikelike maikaʻi, haʻahaʻa haʻahaʻa, hoʻopuehu maikaʻi, haʻahaʻa haʻahaʻa, maikaʻi thermal stability a kiʻekiʻe optical stability, a ʻaʻole e komo i ka mālamalama ʻike a ʻaʻole pili i ke kala. No ka ʻili kiʻekiʻe a me ka ʻāpana mānoanoa o ka ʻāpana haiki, hoʻoheheʻe ʻia, aia ka photostability maikaʻi loa. Me ka molecular weight stabilizer a me ka ultraviolet absorber, he mea nui ka hopena synergistic.
Hoʻohana nui i: polyethylene, polypropylene, polystyrene, olefin copolymer, polyester, polyvinyl chloride palupalu, polyurethane, polyformaldehyde a me nā polyamides, nā mea hoʻopili a me nā sila a pēlā aku.
Manaʻo ʻia ka huina hoʻohui: maʻamau 0.05-0.60%. E hoʻohana ʻia nā hoʻokolohua kūpono e hoʻoholo ai i ka nui kūpono i hoʻohui ʻia i ka hoʻohana pono ʻana.
Hoʻopili ʻia i 25 Kg / pahu pahu. A i ʻole i hoʻopaʻa ʻia e like me nā koi o nā mea kūʻai aku.
E mālama i kahi maloʻo, maloʻo a me ka makani; pale pololei i ka lā.
E ʻoluʻolu e kelepona mai iā mākou no nā palapala pili.
Hoʻolaʻa ʻia ʻo New Venture Enterprise i ka hāʻawi ʻana i ka HALS kiʻekiʻe e hoʻokō i nā pono like ʻole o kēia mau ʻoihana, e hoʻokau i ka hana hou a me ka hoʻomau i ka hoʻomohala ʻana i ka huahana, e ʻoluʻolu e kelepona iā mākou:
