Polyaluminium Chloride, tseem hu ua PAC, yog qhov ua tau zoo heevIndustrial Dej Kho Tshuaj. Raws li ib qho tseem ceeb inorganic polymer flocculant, PAC muaj kev ua tau zoo heev hauv kev tshem tawm cov teeb meem tshem tawm, colloid, organic teeb meem thiab hnyav hlau ions hauv dej vim nws qhov hnyav molecular, siab ceev ceev thiab ceev hydrolysis tus nqi. Hauv tsab xov xwm kawg, peb tau tham txog qhov tseem ceeb ntawm PAC raw khoom. Ces nws ua li cas? Hauv tsab xov xwm no peb yuav tshawb txog qhov teeb meem no hauv qhov tob.
Cov txheej txheem tseem ceeb ntawm PAC
Muaj ntau ntau yam txheej txheem ntawm PAC, xws li neutralization ntawm PAC, nag lossis daus ntawm PAC, thermal decomposition ntau lawm ntawm PAC, thiab lwm yam. Tab sis cov txheej txheem tseem ceeb yog acid-leaching technology thiab sol-gel txoj kev. Tam sim no cia peb tham txog ob txoj haujlwm tseem ceeb no.
* Acid-Leaching Technology
Acid-leaching thev naus laus zis yog cov txheej txheem tseem ceeb rau kev tsim cov qib PAC, uas xav tau cov khoom siv raw xws li bauxite, calcium aluminate, qib hydrochloric acid lossis cov kua qaub pov tseg.
Yog xav paub ntxiv, thov mus saib:Qhov Tseem Ceeb ntawm PAC Flocculant yog dab tsi?
Lub hauv paus ntsiab lus ntawm acid dissolution txoj kev yog zom cov ore nplua, thiab ces ntxiv kua qaub rau yaj. Dissolution feem ntau yog nqa tawm ntawm lub siab thiab kub, tib lub sij hawm ntawm kev sib cais, PAC yog generated. Tom qab ntawd, cov alkalinity yog hloov mus rau ntau tshaj 80% nrog calcium aluminate hmoov.
Al2O3 + 3HCl=Al2(OH)3Cl3
Al2(OH)3Cl3 + CaO·Al2O3 → Al2(OH)nCl6-n + CaCl2
Nws yuav tsum tau muab sau tseg tias cov kua qaub-leaching tshuab yog yooj yim thiab muaj ntau yam raw khoom, tab sis ib tug loj npaum li cas ntawm cov kua qaub yog siv nyob rau hauv cov txheej txheem ntau lawm, thiab kev kho kom zoo ntawm cov kua qaub pov tseg yog heev tsim nyog.
* Txoj kev Sol-Gel
Txoj kev sol-gel yog cov txheej txheem tseem ceeb rau kev tsim cov dej haus qib thiab siab purity PAC, thiab nws cov ntaub ntawv raw yog aluminium hydroxide, calcium aluminate los yog sodium aluminate thiab zaub mov qib hydrochloric acid.
2Al(OH)3 + 3HCl=Al2(OH)3Cl3 + 3H2O
Al2(OH)3Cl3 + CaO·Al2O3 → Al2(OH)nCl6-n + CaCl2
Txoj kev tsim khoom tuaj yeem ua tiav kev sib xyaw ntawm cov khoom siv raw ntawm cov qib molecular, uas yog qhov tsim nyog rau kev npaj PAC nrog kev ua haujlwm siab thiab kev ua haujlwm siab.
Tsis tas li ntawd, PAC kuj tuaj yeem tsim los ntawm* direct dissolution txoj kev, thiab nws cov ntaub ntawv raw yog aluminium scraps, txhuas tshauv thiab txhuas slag los ntawm txhuas ua, thiab hydrochloric acid.
Vim tias kev nqis peev tsawg thiab cov khoom siv, cov txheej txheem yooj yim thiab kev ua haujlwm yooj yim, txoj kev sib cais ncaj qha tau nrov hauv Suav teb xyoo 1970s. Thiab tseem muaj ntau lub tuam txhab me me uas siv txoj kev no. Txawm li cas los xij, cov khoom tsim los ntawm txoj kev no muaj ntau impurities, tshwj xeeb tshaj yog, cov ntsiab lus ntawm cov hlau hnyav yog yooj yim tshaj li tus qauv, thiab cov khoom zoo tsis ruaj khov.
Tus nqi ntawm PAC Flocculant
Raws li ib qho zoo heev polymer flocculant, PAC plays lub luag haujlwm tseem ceeb hauv kev kho dej. Nws tuaj yeem tsis tsuas yog txo cov turbidity thiab chroma hauv dej, tshem tawm cov teeb meem tshem tawm, colloids thiab qee cov organic teeb meem, tab sis kuj tshem tawm qee qhov hnyav hlau ions los ntawm adsorption, nag lossis daus thiab lwm yam txheej txheem. Tsis tas li ntawd, PAC flocculant kuj muaj peev xwm decolorization thiab deodorization, uas yog qhov tseem ceeb rau kev txhim kho cov dej zoo thiab tiv thaiv ib puag ncig ecological.
Hauv luv luv, polyaluminium chloride yog cov tshuaj kho dej txaus. Yog tias koj txaus siab rau nws, txais tos hu rau peb.Aquaenjoytau cog lus los muab cov khoom lag luam zoo thiab tus nqi tsim nyog!
