ʻO Colloidal antimony pentoxide kahi huahana antimony flame retardant i hoʻomohala ʻia e nā ʻāina ʻenehana i ka hopena o 1970s. Hoʻohālikelike ʻia me ka antimony trioxide flame retardant, loaʻa iā ia nā hiʻohiʻona noi aʻe:
1. ʻO ka colloidal antimony pentoxide flame retardant he wahi uwahi. ʻO ka maʻamau, ʻo ka LD50 make o ka antimony trioxide i nā ʻiole (ka ʻōpū o ka ʻōpū) he 3250 mg/kg, aʻo ka LD50 o ka antimony pentoxide he 4000 mg/kg.
2. He kūpono maikaʻi ko Colloidal antimony pentoxide me nā mea hoʻoheheʻe he nui e like me ka wai, methanol, ethylene glycol, acetic acid, dimethylacetamide a me amine formate. Ke hoʻohālikelike ʻia me antimony trioxide, ʻoi aku ka maʻalahi o ka hui ʻana me nā mea hoʻopaʻa ahi halogen e hana i nā ʻano mea hoʻopaʻa ahi composite kiʻekiʻe.
3. ʻO ka nui o ka nui o ka colloidal antimony pentoxide ma lalo o 0.1mm, aʻo ka antimony trioxide he paʻakikī ke hoʻomaʻemaʻe i kēia nui. ʻOi aku ka maikaʻi o ka Colloidal antimony pentoxide no ka noi ʻana i nā fibers a me nā kiʻiʻoniʻoni ma muli o kona liʻiliʻi liʻiliʻi. I ka hoʻololi ʻana o ka flame retardant chemical fiber spinning solution, hoʻohui i ka gelatinized antimony pentoxide hiki ke pale i ke ʻano o ka pale ʻana i ka lua wili a hōʻemi i ka ikaika wili ma muli o ka hoʻohui ʻana i ka antimony trioxide. Ke hoʻohui ʻia ka antimony pentoxide i ka hoʻopau ʻana i ka lapalapa ahi o ka lole, ʻoi aku ka maikaʻi o kona pili ʻana ma ka ʻili o ka lole a me ka lōʻihi o ka hana pale ahi ma mua o ka antimony trioxide.
4. Ke like ka hopena o ka lapalapa ahi, liʻiliʻi ka nui o ka antimony pentoxide colloidal i hoʻohana ʻia ma ke ʻano he lapalapa ahi, ma ke ʻano he 30% wale nō o ka antimony trioxide. No laila, ʻo ka hoʻohana ʻana i ka colloidal antimony pentoxide ma ke ʻano he lapalapa ahi hiki ke hōʻemi i ka hoʻohana ʻana i ka antimony a hoʻomaikaʻi hou aku i nā ʻano kino like ʻole a me ka mīkini o nā huahana pale ahi.
5. Hoʻohana ʻia ka antimony trioxide no nā substrates resin synthetic flame retardant, kahi e ʻona ai i ka catalyst Pd i ka wā electroplating a hoʻopau i ka pūnāwai plating unplated. ʻAʻole loaʻa kēia hemahema Colloidal antimony pentoxide.
No ka mea he koloidal antimony pentoxide flame retardant ma luna o nā hiʻohiʻona, ua hoʻohana nui ʻia ia i nā huahana pale ahi e like me nā kāpeti, nā uhi, resins, rubber, nā lole fiber chemical i nā ʻāina hoʻomohala. ʻEnekinia mai ka Technology R&D Center o UrbanMines Tech. Ua ʻike ʻia ʻo Limited he nui nā ʻano hoʻomākaukau no ka colloidal antimony pentoxide. I kēia manawa, hoʻohana nui ʻia ka hydrogen peroxide no ka hoʻomākaukau ʻana. Nui nā ʻano hana hydrogen peroxide. E lawe kākou i kekahi laʻana: e hoʻohui i 146 mau ʻāpana o ka antimony trioxide a me 194 mau ʻāpana wai i ka reflux reactor, e hoʻoulu e hana i kahi slurry i hoʻopuehu like ʻia, a hoʻohui mālie i nā ʻāpana 114 o 30% hydrogen peroxide ma hope o ka hoʻomehana ʻana i 95 ℃, e hoʻoheheʻe ʻia a reflux no 45 mau minuke, a laila hiki ke loaʻa iā 35% pure colloidal antimony pentoxide solution. Ma hope o ka hoʻoluʻu iki ʻana o ka colloidal solution, kānana e wehe i ka mea hiki ʻole ke hoʻoheheʻe ʻia, a laila maloʻo ma 90 ℃, hiki ke loaʻa ka pauka hydrated keʻokeʻo o ka antimony pentoxide. melemele a viscous, a laila maloʻo no ka loaʻa ʻana o ka pauka antimony pentoxide melemele.
Ke hoʻohana nei i ka antimony trioxide ma ke ʻano he mea maka no ka hoʻomākaukau ʻana i ka colloidal antimony pentoxide ma ke ʻano hydrogen peroxide, maʻalahi ke ʻano, pōkole ke kaʻina hana ʻenehana, haʻahaʻa ka waiwai o nā lako, a hoʻohana piha ʻia nā kumuwaiwai antimony. Hiki i hoʻokahi tona o ka antimony trioxide maʻamau ke hana i 1.35 tons o ka colloidal antimony pentoxide maloʻo pauka a me 3.75 tons o 35% colloidal antimony pentoxide solution, hiki ke hoʻoikaika i ka hana ʻana o nā huahana pale ahi a hoʻonui i nā noi ākea o nā huahana pale ahi.
