Colloidal antimony pentoxide yog antimony nplaim taws retardant khoom tsim los ntawm industrialized lub teb chaws nyob rau hauv lig 1970s.Piv nrog antimony trioxide nplaim retardant, nws muaj cov yam ntxwv hauv qab no:
1. Lub colloidal antimony pentoxide nplaim retardant muaj cov pa luam yeeb me me.Feem ntau, cov tshuaj tua kab mob LD50 ntawm antimony trioxide rau nas (mob plab) yog 3250 mg / kg, thaum LD50 ntawm antimony pentoxide yog 4000 mg / kg.
2. Colloidal antimony pentoxide muaj kev sib raug zoo nrog ntau cov kuab tshuaj organic xws li dej, methanol, ethylene glycol, acetic acid, dimethylacetamide thiab amine formate.Piv nrog antimony trioxide, nws yooj yim dua los sib xyaw nrog halogen nplaim taws retardants los tsim ntau yam hluav taws xob hluav taws xob zoo sib xws.
3. Qhov loj me me ntawm colloidal antimony pentoxide feem ntau yog tsawg dua 0.1 hli, thaum antimony trioxide nyuaj rau refine rau hauv qhov me me no.Colloidal antimony pentoxide yog qhov tsim nyog rau daim ntawv thov hauv fibers thiab films vim nws qhov me me particle loj.Hauv kev hloov kho cov nplaim hluav taws kub retardant chemical fiber spinning tov, ntxiv gelatinized antimony pentoxide tuaj yeem zam qhov tshwm sim ntawm thaiv lub qhov spinning thiab txo lub zog spinning los ntawm kev ntxiv antimony trioxide.Thaum antimony pentoxide ntxiv rau cov nplaim retardant tiav ntawm cov ntaub, nws cov adhesion ntawm cov ntaub thiab durability ntawm cov nplaim retardant muaj nuj nqi zoo dua li cov antimony trioxide.
4. Thaum cov nplaim retardant zoo ib yam, tus nqi ntawm colloidal antimony pentoxide siv los ua cov nplaim hluav taws xob me me, feem ntau tsuas yog 30% ntawm antimony trioxide.Yog li ntawd, kev siv cov colloidal antimony pentoxide ua cov nplaim hluav taws tuaj yeem txo qhov kev noj cov tshuaj antimony thiab ntxiv dag zog rau ntau yam kev siv lub cev thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob.
5. Antimony trioxide yog siv rau cov nplaim hluav taws-retardant hluavtaws resin substrates, uas yuav lom Pd catalyst thaum lub sij hawm electroplating thiab rhuav tshem lub pas dej ua ke uas tsis muaj plating.Colloidal antimony pentoxide tsis muaj qhov tsis txaus no.
Vim hais tias colloidal antimony pentoxide nplaim retardant muaj cov yam ntxwv saum toj no, nws tau siv dav hauv cov khoom siv hluav taws xob xws li ntaub pua plag, coatings, resins, roj hmab, tshuaj fiber ntau hauv cov teb chaws tsim.Engineers los ntawm Technology R & D Center ntawm UrbanMines Tech.Txwv pom tias muaj ntau txoj kev npaj rau colloidal antimony pentoxide.Tam sim no, hydrogen peroxide feem ntau yog siv rau kev npaj.Kuj tseem muaj ntau hom kev siv hydrogen peroxide.Tam sim no cia peb ua ib qho piv txwv: ntxiv 146 feem ntawm antimony trioxide thiab 194 feem ntawm cov dej rau lub reflux reactor, do ua ib tug uniformly dispersed slurry, thiab maj mam ntxiv 114 feem ntawm 30% hydrogen peroxide tom qab cua sov rau 95 ℃, ua rau nws oxidize thiab reflux rau 45 feeb, thiab tom qab ntawd 35% purity colloidal antimony pentoxide tov tau.Tom qab cov tshuaj colloidal txias me ntsis, lim kom tshem tawm cov teeb meem insoluble, thiab tom qab ntawd qhuav ntawm 90 ℃, cov hmoov dawb hydrated ntawm antimony pentoxide tuaj yeem tau.Ntxiv 37.5 feem ntawm triethanolamine ua tus stabilizer thaum lub sij hawm pulping, npaj colloidal antimony pentoxide tov yog daj thiab khov, thiab tom qab ntawd qhuav kom tau daj antimony pentoxide hmoov.
Siv antimony trioxide ua raw khoom los npaj colloidal antimony pentoxide los ntawm hydrogen peroxide txoj kev, txoj kev yog yooj yim, cov txheej txheem thev naus laus zis yog luv, cov cuab yeej siv peev tsawg, thiab cov khoom siv antimony tau siv tag nrho.Ib tuj ntawm zoo tib yam antimony trioxide tuaj yeem tsim 1.35 tons ntawm colloidal antimony pentoxide qhuav hmoov thiab 3.75 tons ntawm 35% colloidal antimony pentoxide tov, uas tuaj yeem txhawb kev tsim cov khoom siv hluav taws xob thiab nthuav dav daim ntawv thov kev cia siab ntawm cov khoom siv hluav taws xob.
