Antioxidant 626 CAS 26741-53-7
ʻO kēia huahana he pauka keʻokeʻo keʻokeʻo me kahi helu heheʻe o 160-175 ° C, kahi kukui uila o 168 ° C, a me kahi wela wela o 421 ° C. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me toluene, methyl chloride, a me chloroform, hiki ke hoʻoheheʻe iki ʻia i ka waiʻona, a hiki ʻole ke hoʻoheheʻe ʻia i ka wai. ʻO ka Antioxidant 626 he keʻokeʻo a keʻokeʻo keʻokeʻo me ka haʻahaʻa haʻahaʻa a ʻoi aku ka maikaʻi. Hoʻohana pinepine ʻia i ka hui pū ʻana me nā antioxidants phenol i kāohi ʻia.

1. Hoʻohana nui ʻia ʻo Antioxidant 626 i ka synthesis a me ka hana ʻana o nā plastics like ʻole e like me polypropylene, polyethylene, ABS, polycarbonate fiber a me polyester resin. ?
2. ʻO ka Antioxidant 626 he antioxidant kōkua phosphite me ka haʻahaʻa haʻahaʻa, hiki ke pale pono i ka discoloration polymer, hoʻemi i ka helu degradation polymer, a hoʻomaikaʻi i ke kū'ē o ka resin i ke kinoea mae. He kūpono loa ia no nā polyolefins a me ka olefin copolymers, polycarbonate, polyamide a me nā mea ʻenehana ʻenehana ʻē aʻe, a me ka pahu, nā uhi a me nā mea hoʻopili. Hiki i ka hoʻohui ʻana o antioxidant 626 ke hoʻomaikaʻi nui i ka paʻa o ka hana ʻana o ka mea, a hoʻohana nui ʻia i ka hana ʻana o ka polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polystyrene, polyvinyl chloride a me nā thermoplastics a me nā elastomers. waena. Eia kekahi, he maikaʻi loa ka antioxidant 626 i ka pale ʻana i ka discoloration ma muli o ka māmā a me ka wela, a me kekahi hopena stabilization māmā, hiki ke hoʻomaikaʻi i ka mālamalama, ke kūpaʻa wela, ka ikaika mechanical a me ke kūpaʻa kala o ka huahana, a laila e hoʻonui ai i ke ola o ka huahana. huahana.
3. Loaʻa i ka Antioxidant 626 nā waiwai kemika paʻa a me ka launa maikaʻi me ka hapa nui o nā polymers. He phosphite auxiliary antioxidant ia. ʻAʻole hiki i kāna hoʻohana ke hoʻomaikaʻi wale i ka paʻa o ka hana ʻana o nā mea, akā hoʻomaikaʻi hoʻi i ka mālamalama, ke kūpaʻa wela, ka ikaika mechanical a me ke kūpaʻa kala o nā huahana. He mea hoʻohui koʻikoʻi i hoʻohana nui ʻia i ka ʻoihana plastics.
25kg / ʻeke a i hoʻonohonoho ʻia e like me nā pono o ka mea kūʻai aku
