Acid yakashambidzwa jecha requartz

Quartz jecha pickling uye pickling maitiro akatsanangurwa

Pakusarudzwa kwejecha requartz rakacheneswa uye jecha requartz rakacheneswa, zvakaoma kuzadzisa zvinodiwa zveyakajairwa nzira dzekubatsirikana, kunyanya kune iyo iron oxide firimu pamusoro pejecha requartz uye tsvina yesimbi mumitswe.Kuti uvandudze zvirinani kunaka uye goho rekucheneswa kwejecha requartz, rakasanganiswa nehunhu hwejecha requartz risinganyunguriki muasidhi uye rinonyungudika zvishoma muKOH mhinduro, iyo acid leaching nzira yave nzira inodiwa yekurapa jecha requartz.

Quartz jecha pickling kurapwa ndeye kurapa jecha requartz nehydrochloric acid, sulfuric acid, oxalic acid kana hydrofluoric acid yekunyungudutsa iron.

Basic process ye quartz sand pickling

I proportioning acid lotion

Matani ejecha anofanira kugadzirwa ne7-9% oxalic acid, 1-3% hydrofluoric acid uye 90% mvura musanganiswa;Inoda 2-3.5 matani emvura, kana mvura ikashandiswazve, ipapo chete 0.1 matani emvura anodiwa kuchenesa tani yejecha, mukushanda kwejecha rekuchenesa, zvinongozounza yakawanda yejecha kumusoro;Quartz jecha pickling kurapwa ndeye kurapa jecha requartz nehydrochloric acid, sulfuric acid, oxalic acid kana hydrofluoric acid yekunyungudutsa iron.

Ⅱ Musanganiswa wepickling

Mushonga wekunhonga unopinzwa mutangi rekunhonga uye wowedzerwa zvinoenderana nechikamu chehydrochloric acid yemukati senge 5% yehuremu hwejecha kuti ive nechokwadi chekuti jecha requartz rakanyikwa mumushonga wekunhonga uye iyo hydrochloric acid yemukati inenge 5% ye jecha uremu.

Ⅲ Asidhi-yakagezwa quartz jecha
① Iyo nguva yejecha requartz kunyudza mhinduro inowanzoita maawa matatu-5, iyo chaiyo kudiwa kwekuwedzera kana kuderedza nguva yekunyura zvinoenderana neganda reyero rejecha requartz, kana mhinduro yekunhonga nejecha requartz rinogona kumutswa kwenguva yakati. yenguva, inoteverwa nekushandiswa kwemidziyo yekudziya kupisa mhinduro kune imwe tembiricha, inogona kuderedza nguva yekuchera.

② Kushandiswa kweoxalic acid uye green alum seanoderedza agent pickling kurapwa kunogona kuvandudza kunyungudika kwesimbi, zvakare, mvura, oxalic acid, green alum zvinoenderana nechikamu chemhinduro pane imwe tembiricha, jecha requartz uye mhinduro zvinoenderana. neimwe chikamu chekusanganisa, kubvongodza, kurapwa kwemaminetsi mashoma, mhinduro yacho inosefa uye inorapwa mushure mekupora.

③ Hydrofluoric acid kurapwa: Mhedzisiro yacho yakanaka kana hydrofluoric acid kurapwa ikaiswa yega, asi iyo yekumisikidza yakakwira.Kana yakagovaniswa ne sodium dithionite, yakaderera kudzika kwe hydrofluoric acid inogona kushandiswa.

Imwe mutsara we hydrochloric acid uye hydrofluoric acid solution yakasanganiswa mu quartz jecha slurry panguva imwe chete maererano nehuwandu;Inogonawo kurapwa nehydrochloric acid solution kutanga, yakashambidzwa uye yozobatwa ne hydrofluoric acid, inobatwa pakupisa kwemaawa 2-3, uye yozocheneswa nekucheneswa.

Cherechedza:

Kana hydrofluoric acid yakashandiswa kuita acid soak quartz jecha, maitiro acho akanyanya kuoma.Pamusoro pekunyungudika kwesimbi mune acidic midhiya, HF inogona zvakare kuita nequartz pachayo kunyungudutsa SiO2 uye mamwe silicates ehumwe ukobvu pamusoro.

Nekudaro, izvi zvinonyanya kushanda pakuchenesa pamusoro pejecha requartz uye kubvisa iron uye kumwe kusvibiswa kwetsvina, saka hydrofluoric acid yakanaka kune acid leaching yequartz.Nekudaro, HF ine muchetura uye inoparadza zvakanyanya, saka iyo asidhi inobvisa tsvina yemvura inoda kurapwa kwakakosha.

iv Acid kupora uye deacidization

Sukurudza jecha requartz-asidhi yakashambidzwa nemvura ka2-3, wobva wamisa ne 0.05% -0.5% yesodium hydroxide (caustic soda) alkaline solution, uye nguva ye neutralization inenge 30-60 maminetsi, uye ona kuti quartz yose. jecha haripindiri panzvimbo.Kana iyo pH yasvika alkaline, unogona kusunungura lye uye wosuka 1-2 nguva kusvika pH isina kwayakarerekera.

Ⅴ Dry quartz jecha

Ijecha re quartz rinofanira kudonhedzwa nemvura mushure mekubviswa kweasidhi, uye ipapo jecha re quartz rinofanira kuomeswa mumidziyo yekuomesa.

Ⅵ kuongorora, kusarudzwa kwemavara uye kurongedza, nezvimwe.

Izvo zviri pamusoro ndiyo nzira yekutanga yequartz jecha pickling uye leaching yekurapa maitiro, quartz jecha ore ine kupararira kwakapararira munyika yedu, saka kune misiyano muchimiro chejecha requartz, mukucheneswa kwejecha requartz inodawo kune mamwe matambudziko chaiwo. kuongorora, gadzira yakakodzera quartz jecha rekuchenesa maitiro.
