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 nō hoʻi 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 maloʻo iki ʻana o ka colloidal solution, kānana e wehe i ka mea hiki ʻole ke hoʻoheheʻe ʻia, a laila maloʻo i ka 90 ℃, hiki ke loaʻa ka pauka hydrated keʻokeʻo o ka antimony pentoxide. melemele a viscous, a laila maloʻo e loaʻa ai 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.
