Isanti ye-quartz ehlanjwe nge-asidi
Inkqubo yokukha isanti yeQuartz kunye nokukha ichazwe ngokweenkcukacha
Ekukhetheni isanti ye-quartz ecocekileyo kunye nesanti ye-quartz ecocekileyo kakhulu, kunzima ukuhlangabezana neemfuno zeendlela eziqhelekileyo zokuphucula, ngakumbi kwifilimu ye-iron oxide kumphezulu wesanti ye-quartz kunye nokungcola kwesinyithi kwimifantu. Ukuze kuphuculwe ngcono umgangatho kunye nemveliso yokucocwa kwesanti ye-quartz, kunye neempawu zesanti ye-quartz enganyibilikiyo kwi-asidi kwaye inyibilikayo kancinci kwisisombululo se-KOH, indlela yokukhuhla i-asidi ibe yindlela efunekayo yokunyanga isanti ye-quartz.
Unyango lokucola isanti yeQuartz lukunyanga isanti yeQuartz nge-hydrochloric acid, i-sulfuric acid, i-oxalic acid okanye i-hydrofluoric acid ukuze kunyibilikiswe isinyithi.
Inkqubo esisiseko yokukha isanti ye-quartz
I-lotion ye-asidi elinganiselayo
Iitoni zesanti kufuneka zenziwe nge-7-9% ye-oxalic acid, i-1-3% ye-hydrofluoric acid kunye nomxube wamanzi we-90%; Ifuna iitoni ezi-2-3.5 zamanzi, ukuba amanzi aphinda asetyenziswe, kufuneka iitoni ezi-0.1 zamanzi kuphela ukucoca itoni yesanti, kumsebenzi wokucoca isanti, ngokuqinisekileyo kuya kunyusa uninzi lwesanti; Unyango lokucoca isanti yeQuartz kukunyanga isanti yeQuartz nge-hydrochloric acid, i-sulfuric acid, i-oxalic acid okanye i-hydrofluoric acid ukuze kunyibilike isinyithi.
Ⅱ Umxube wokukha
Isisombululo se-pickling sifakwa kwi-pickling tank kwaye songezwa ngokwemilinganiselo yomxholo we-hydrochloric acid malunga ne-5% yobunzima besanti ukuqinisekisa ukuba isanti ye-quartz imanziswe kwisisombululo se-pickling kwaye umxholo we-hydrochloric acid umalunga ne-5% yobunzima besanti.
Isanti ye-quartz ehlanjwe nge-asidi
① Ixesha lokuba isanti ye-quartz imanzise isisombululo se-pickling ngokuqhelekileyo ziiyure ezi-3-5, imfuneko ethile yokwandisa okanye ukunciphisa ixesha lokumanzisa ngokwesikhumba esityheli sesanti ye-quartz, okanye isisombululo se-pickling kunye nesanti ye-quartz zinokuxutywa ixesha elithile, kulandele ukusetyenziswa kwezixhobo zokufudumeza ukufudumeza isisombululo kubushushu obuthile, kunokunciphisa ixesha le-pickling.
② Ukusetyenziswa kwe-oxalic acid kunye ne-green alum njengonyango lokunciphisa i-pickling agent kunokuphucula ukunyibilika kwesinyithi, ngokuhambelana namanzi, i-oxalic acid, i-green alum ngokuhambelana nomlinganiselo wesisombululo kubushushu obuthile, isanti ye-quartz kunye nesisombululo ngokuhambelana nomlinganiselo othile wokuxuba, ukuxuba, unyango imizuzu embalwa, isisombululo siyahluzwa kwaye siphathwe emva kokubuyiselwa.
③ Unyango lwe-hydrofluoric acid: Isiphumo siba sihle xa unyango lwe-hydrofluoric acid lusetyenziswa lodwa, kodwa uxinzelelo luphezulu. Xa kusetyenziswa i-sodium dithionite, uxinano oluphantsi lwe-hydrofluoric acid lungasetyenziswa.
Ingqokelela ethile ye-hydrochloric acid kunye nesisombululo se-hydrofluoric acid zixutywe kwi-quartz sand slurry ngaxeshanye ngokwemilinganiselo; Inganyangwa ngesisombululo se-hydrochloric acid kuqala, ihlanjwe ize iphathwe nge-hydrofluoric acid, iphathwe kubushushu obuphezulu iiyure ezi-2-3, ize emva koko ihluzwe kwaye icocwe.
Phawula:
Ukuba i-hydrofluoric acid isetyenziselwa ukufunxa isanti ye-quartz nge-asidi, impendulo iyinkimbinkimbi ngakumbi. Ukongeza ekunyibilikeni kwesinyithi kwi-acid media, i-HF ingenza ne-quartz ngokwayo ukuze inyibilikise i-SiO2 kunye nezinye ii-silicates zobukhulu obuthile kumphezulu.
Nangona kunjalo, oku kusebenza ngakumbi ekucoceni umphezulu wesanti ye-quartz kunye nokususa isinyithi kunye nolunye ungcoliseko lokungcola, ngoko ke i-hydrofluoric acid ilungile ekukhupheni i-asidi ye-quartz. Nangona kunjalo, i-HF iyingozi kwaye idla ngokugqwala kakhulu, ngoko ke amanzi amdaka akhupha i-asidi afuna unyango olukhethekileyo.
Ukubuyiselwa kwe-asidi ye-Iv kunye nokunciphisa i-asidi
Hlamba isanti ye-quartz ehlanjwe nge-asidi ngamanzi izihlandlo ezi-2-3, uze uyinyibilikise ngesisombululo se-alkaline se-0.05%-0.5% ye-sodium hydroxide (caustic soda), kwaye ixesha lokuyinyibilikisa limalunga nemizuzu engama-30-60, kwaye uqinisekise ukuba yonke isanti ye-quartz ayisuswanga endaweni yayo. Xa i-pH ifikelela kwi-alkaline, ungayikhulula i-lye kwaye uyihlambe izihlandlo ezi-1-2 de i-pH ingabi mdaka.
Ⅴ Isanti ye-quartz eyomileyo
Isanti ye-quartz kufuneka ikhutshwe amanzi emva kokukhupha i-asidi, emva koko isanti ye-quartz mayimiswe kwizixhobo zokomisa.
Ⅵ ukucoca, ukukhetha imibala kunye nokupakishwa, njl.
Oku kungentla yinkqubo esisiseko yokucola isanti ye-quartz kunye nenkqubo yonyango lwe-leaching, i-ore yesanti ye-quartz inokusasazwa ngokubanzi kwilizwe lethu, ngoko ke kukho umahluko kuhlobo lwesanti ye-quartz, ekuhlanjululweni kwesanti ye-quartz kufuneka kuhlalutywe iingxaki ezithile, kuphuhliswe inkqubo efanelekileyo yokucocwa kwesanti ye-quartz.
