Ma kēia pepa, loiloi mākou i ʻekolu mau mea hoʻoheheʻe UV. Loaʻa iā lākou nā mea maikaʻi a me nā ʻano pili. ʻO ka mea mua, e hoʻokomo i ka UV absorber:
ʻO Omnistab UV 1577 TF he toluene-free hydroxyphenyltriazine UV absorber. Loaʻa i ka volatility haʻahaʻa a me ka hoʻohālikelike maikaʻi me nā ʻano polymers. Hāʻawi ia i ka polycarbonate a me ka polyester me ke kūpaʻa ʻoi aku ka maikaʻi o ka wā ma mua o ka benzotriazole -puʻu UV maʻamau.
ʻO Omnistab UV 3030 kahi mea hoʻoheheʻe ultraviolet haʻahaʻa haʻahaʻa haʻahaʻa cyanoacrylate (UVA) e hāʻawi ana i ka photostability maikaʻi loa i nā polymers i hana ʻia. Me ke kūpaʻa wela kiʻekiʻe, ʻaʻohe kala ʻokoʻa. Hiki ke hoʻohana ʻia no ka hoʻopaʻa ʻana i nā polymers akaka loa me nā mahana extrusion kiʻekiʻe.
Hāʻawi ʻo Omnistab UV 3638 i ka ikaika a ākea o UV absorption me ka hāʻawi kala ʻole. Hāʻawi haʻahaʻa volatility. Hāʻawi kiʻekiʻe ka pale pale UV.
Omnistab UV 1577TF
ʻO kēia ka hydroxybenzotriazine UV absorber. Eia kekahi, ua ikaika ia ma nā wahi ʻelua o UV-B a me UV-A. Hōʻike ia i nā hopena maikaʻi loa i ka stabilization māmā PET. Manaʻo ʻia ʻo UV 1577 TF no PC akā ʻaʻole i ʻōlelo ʻia e like me ka UV 3030 e like me ka mohala a me ke kūkulu ʻana i kekahi manawa i ka wā o ka hana ʻana i nā pepa ʻike PC. Hiki ke hoʻohana ʻia no ka hoʻopaʻa māmā ʻana i nā plastik ABS a me nā plastics ʻenehana ʻē aʻe. ʻO ka mea nui loa, ʻoi aku ka maikaʻi ma mua o ka hydroxytriazole-e like me ka Omnistab UV 329. Manaʻo ʻia no ka pepa PET kūpaʻa 20 makahiki. ʻAʻole maikaʻi e like me ka Omnistab UV 1600 (ke kūkulu ʻia nei i kēia manawa). No ka laʻana, koi ʻia nā kiʻekiʻe kiʻekiʻe e hoʻokō i ka photostability like.
Omnistab UV 3030
He cyanoacrylate type UV absorber kēia i kūpono loa ma ka māhele UV-B. He kūpono loa no ka hoʻopaʻa ʻana o ka polycarbonate (PC). Paʻa ia ma ka mahana hana o PC (ma kahi o 300C) me ka ʻole o ka mohala a kūkulu ʻia-ma luna o nā mea paahana. Eia kekahi, hiki ke ʻōlelo ʻia no 20 mau makahiki o ka PC ma nā kūlana waho me ka Omnistab UV 1600.
Omnistab UV 3638
ʻO kēia ka ʻano benzoxazine UV absorber me ka ikaika o ka hoʻomoe ʻana i ka UV-A māhele a me ka emi ʻana ma ka UV-B māhele. Pono no ka hoʻopaʻa māmā ʻana o PET. Eia naʻe, ʻoi aku ka haʻahaʻa ma mua o UV 1577. Loaʻa iā ia ke kūpaʻa wela kiʻekiʻe. Loaʻa no nā polymers ʻenehana like ʻole. I ka hopena, no nā huahana liʻiliʻi loa, paipai mākou i ka Omnistab UV 3638. No ka laʻana, no 10 mau makahiki).
