Mchenga wa quartz wotsukidwa ndi asidi

Tsatanetsatane wa njira yopezera mchenga wa Quartz ndi kusonkhanitsa

Posankha mchenga wa quartz woyeretsedwa ndi mchenga wa quartz woyeretsedwa kwambiri, zimakhala zovuta kukwaniritsa zofunikira za njira zodziwika bwino zopangira zinthu, makamaka pa filimu ya iron oxide pamwamba pa mchenga wa quartz ndi zinyalala zachitsulo zomwe zili m'ming'alu. Pofuna kukonza bwino ubwino ndi zokolola za kuyeretsa mchenga wa quartz, kuphatikiza ndi makhalidwe a mchenga wa quartz wosasungunuka mu asidi komanso wosungunuka pang'ono mu yankho la KOH, njira yochotsera asidi yakhala njira yofunika kwambiri yochizira mchenga wa quartz.

Chithandizo cha kusonkhanitsa mchenga wa quartz ndi kuchiza mchenga wa quartz ndi hydrochloric acid, sulfuric acid, oxalic acid kapena hydrofluoric acid kuti isungunuke chitsulo.

Njira yoyambira yopangira mchenga wa quartz

Lotion yoyezera asidi

Matani a mchenga amafunika kupangidwa ndi 7-9% oxalic acid, 1-3% hydrofluoric acid ndi 90% madzi osakaniza; Pamafunika matani 2-3.5 a madzi, ngati madziwo abwezeretsedwanso, ndiye kuti matani 0.1 okha a madzi amafunika kuyeretsa tani imodzi ya mchenga, poyeretsa mchenga, mosakayikira adzakweza mchenga wambiri; Chithandizo cha pickling cha mchenga wa quartz ndi kuchiza mchenga wa quartz ndi hydrochloric acid, sulfuric acid, oxalic acid kapena hydrofluoric acid kuti asungunuke chitsulo.

Ⅱ Kusakaniza kokoma

Njira yothetsera vutoli imalowetsedwa mu thanki yothira mchere ndipo imawonjezedwa molingana ndi kuchuluka kwa asidi wa hydrochloric monga pafupifupi 5% ya kulemera kwa mchenga kuti zitsimikizire kuti mchenga wa quartz wanyowa mu njira yothetsera vutoli ndipo asidi wa hydrochloric acid ndi pafupifupi 5% ya kulemera kwa mchenga.

Ⅲ Mchenga wa quartz wotsukidwa ndi asidi
① Nthawi yomwe mchenga wa quartz umanyowetsa madzi a pickling nthawi zambiri imakhala maola 3-5, chifukwa chake kufunikira kowonjezera kapena kuchepetsa nthawi yonyowetsa madzi malinga ndi khungu lachikasu la mchenga wa quartz, kapena njira yonyowetsa madzi ndi mchenga wa quartz zimatha kusunthidwa kwa nthawi, kutsatiridwa ndi kugwiritsa ntchito zida zotenthetsera kutentha kwa madziwo, kungachepetse nthawi yonyowetsa madziwo.

② Kugwiritsa ntchito oxalic acid ndi green alum ngati mankhwala ochepetsera kungathandize kusungunula chitsulo, motero, madzi, oxalic acid, green alum mogwirizana ndi kuchuluka kwa yankho pa kutentha kwina, mchenga wa quartz ndi yankho mogwirizana ndi kuchuluka kwa kusakaniza, kusakaniza, chithandizo kwa mphindi zochepa, yankholo limasefedwa ndikuchiritsidwa pambuyo pochira.

③ Chithandizo cha hydrofluoric acid: Zotsatira zake zimakhala zabwino ngati chithandizo cha hydrofluoric acid chikugwiritsidwa ntchito chokha, koma kuchuluka kwake kumakhala kwakukulu. Mukagawana ndi sodium dithionite, kuchuluka kochepa kwa hydrofluoric acid kungagwiritsidwe ntchito.

Kuchuluka kwa hydrochloric acid ndi hydrofluoric acid solution zinasakanizidwa mu slurry ya mchenga wa quartz nthawi yomweyo malinga ndi kuchuluka kwake; Ikhozanso kuchiritsidwa ndi hydrochloric acid solution poyamba, kutsukidwa kenako kuchiritsidwa ndi hydrofluoric acid, kuchiritsidwa kutentha kwambiri kwa maola 2-3, kenako kusefedwa ndikutsukidwa.

Zindikirani:

Ngati hydrofluoric acid imagwiritsidwa ntchito kunyowetsa mchenga wa quartz ndi asidi, izi zimakhala zovuta kwambiri. Kuwonjezera pa kusungunuka kwa chitsulo mu acidic media, HF imathanso kuchitapo kanthu ndi quartz yokha kuti isungunuke SiO2 ndi ma silicates ena a makulidwe ena pamwamba.

Komabe, izi ndizothandiza kwambiri poyeretsa pamwamba pa mchenga wa quartz ndikuchotsa chitsulo ndi zinthu zina zodetsa, kotero hydrofluoric acid ndi yabwino pochotsa asidi wa quartz. Komabe, HF ndi poizoni komanso imawononga kwambiri, kotero madzi otayira omwe amachotsa asidi amafunika chithandizo chapadera.

Kubwezeretsa asidi mu Iv ndi kuchepetsa asidi

Tsukani mchenga wa quartz wotsukidwa ndi asidi ndi madzi kawiri kapena katatu, kenako chepetsani ndi 0.05%-0.5% ya sodium hydroxide (caustic soda) alkaline solution, ndipo nthawi yochepetsera ndi pafupifupi mphindi 30-60, ndipo onetsetsani kuti mchenga wonse wa quartz wachotsedwa pamalo pake. pH ikafika pa alkaline, mutha kumasula lye ndikutsuka nthawi 1-2 mpaka pH isakhale yofanana.

Ⅴ Mchenga wouma wa quartz

Mchenga wa quartz uyenera kuchotsedwa madzi pambuyo poti asidi wachotsedwa, kenako mchenga wa quartz uyenera kuumitsidwa mu zipangizo zoumitsira.

Ⅵ kuphimba, kusankha mitundu ndi kulongedza, ndi zina zotero.

Zomwe zili pamwambapa ndi njira yoyambira yopangira mchenga wa quartz ndi njira yochizira, mchenga wa quartz uli ndi kufalikira kwakukulu m'dziko lathu, kotero pali kusiyana pakati pa mtundu wa mchenga wa quartz, poyeretsa mchenga wa quartz, ndikofunikiranso kusanthula mavuto enaake, kupanga njira yoyenera yoyeretsera mchenga wa quartz.
