Te kirikiri kiripaka kua horoia waikawa

Ko nga mahi toki kirikiri kirikiri me nga mahi toka

I roto i te whiriwhiringa o te kirikiri kirikiri parakore me te kirikiri kirikiri teitei, he uaua ki te whakatutuki i nga whakaritenga o nga tikanga whaihua tikanga, ina koa mo te kiriata waikura rino i runga i te mata o te kirikiri kirikiri me nga poke rino i roto i nga kapiti.Kia pai ake ai te whakapai ake i te kounga me te hua o te purenga kirikiri kirikiri, ka honoa me nga ahuatanga o te kirikiri kirikiri kore e rewa i roto i te waikawa me te paku wairewa i roto i te otinga KOH, kua riro te tikanga rewharewha waikawa hei tikanga mo te rongoa kirikiri kiripaka.

Ko te maimoatanga kirikiri kirikiri ko te rongoa i te kirikiri kiripaka me te waikawa maaota, te waikawa sulfuric, te waikawa oxalic, te waikawa puwhawai ranei hei whakakore i te rino.

Te tukanga taketake o te tiki kirikiri kiripaka

Ka whakataurite ahau i te wai waikawa

Me hanga nga toni onepu ki te 7-9% oxalic acid, 1-3% hydrofluoric acid me te 90% te ranunga wai;Me 2-3.5 tone te wai, mena ka recycled te wai, katahi ka 0.1 tone te wai hei horoi i te tone onepu, i roto i te mahi horoi kirikiri, kare e kore ka piki ake te nuinga o te onepu;Ko te maimoatanga kirikiri kirikiri ko te rongoa i te kirikiri kiripaka me te waikawa maaota, te waikawa sulfuric, te waikawa oxalic, te waikawa puwhawai ranei hei whakakore i te rino.

Ⅱ Whakaranu pikara

Ka werohia te wairewa pikara ki roto i te taika pikapi, ka tapirihia kia rite ki te wahanga o te waikawa waikawa maata mo te 5% o te taumaha o te onepu ki te whakarite kia rukuhia te kirikiri kiripaka ki roto i te wairewa pikara me te ihirangi waikawa maataa ko te 5% o te. taumaha kirikiri.

Ⅲ Te kirikiri kiripaka kua horoia waikawa
① Ko te wa mo te kirikiri kiripaka ki te whakamakuku i te wairewa rakaraka ko te tikanga 3-5 haora, ko te hiahia motuhake ki te whakanui ake, ki te whakaheke ranei i te wa whakamakuku kia rite ki te kiri kowhai o te kirikiri kiripaka, ka taea ranei te whakakorikori i te otinga tiki me te onepu kiripaka mo tetahi wa o te wa, whai muri i te whakamahi i nga taputapu whakamahana ki te whakamahana i te otinga ki tetahi pāmahana, ka taea te whakaiti i te wa pickling.

② Ma te whakamahi i te waikawa oxalic me te alum kaakaariki hei whakaiti i te maimoatanga pickling agent ka taea te whakapai ake i te memehatanga o te rino, i roto i te huri, te wai, te waikawa oxalic, te alum matomato i runga i te waahanga o te otinga i tetahi pāmahana, te kirikiri kirikiri me te otinga i runga ano. me etahi waahanga o te whakaranu, te whakaoho, te maimoatanga mo etahi meneti, ka tohua te otinga me te rongoa i muri i te whakaoranga.

③ Te maimoatanga waikawa Hydrofluoric: He pai te painga ina whakamahia anake te maimoatanga waikawa hydrofluoric, engari he teitei ake te kukū.Ina tohaina ki te konutai dithionite, ka taea te whakamahi i nga kukū iti o te waikawa waiwaro.

Ko tetahi kukū o te waikawa pūhaumāota me te wairewa waikawa pūhauwai i konatunatua ki roto i te slurry kiripaka kiripaka i te wa ano i runga i te rahinga;Ka taea hoki te rongoa ki te wairewa waikawa maaota i te tuatahi, ka horoi katahi ka rongoatia ki te waikawa hydrofluoric, ka pangia ki te wera nui mo te 2-3 haora, katahi ka tātarihia ka horoia.

Tuhipoka:

Mēnā ka whakamahia te waikawa pūhāwai ki te waikawa waiwai te kirikiri kiripaka, he uaua ake te tauhohenga.I tua atu i te whakakorenga o te rino i roto i te pāpāho waikawa, ka taea hoki e te HF te tauhohe me te quartz ano ki te whakakore i te SiO2 me etahi atu silicates o tetahi matotoru i runga i te mata.

Engari, he pai ake tenei mo te horoi i te mata o te kirikiri kiripaka me te whakakore i te rino me etahi atu parahanga poke, na reira he pai te waikawa hydrofluoric mo te riihi waikawa o te kiripaka.Heoi, he paitini te HF me te tino pirau, na reira me whakamaarama motuhake te wai parae ree waikawa.

Iv Te whakaora me te whakakore i te waikawa

Horoihia te kirikiri kiripaka kua horoia waikawa ki te wai 2-3 wa, katahi ka whakakorea ki te 0.05% -0.5% o te konutai waiwa (caustic houra) wairewa kawakore, a ko te wa whakakorenga he 30-60 meneti, me te whakarite ko te kiripaka katoa. kua whakakorehia te onepu ki te waahi.Ka tae te pH ki te kawakore, ka taea e koe te tuku i te rei me te horoi kia 1-2 nga wa kia kore noa te pH.

Ⅴ kiripaka kiripaka maroke

Ko te kirikiri kiripaka me whakaheke i te wai i muri i te tangohanga o te waikawa, katahi ka whakamarokehia te kirikiri kiripaka i roto i nga taputapu whakamaroke.

Ⅵ te tirotiro, te kowhiringa tae me te kapi, aha atu.

Ko te i runga ake ko te tukanga taketake o te kiripaka kirikiri pickling me te riihi tukanga maimoatanga, kiripaka kirikiri ore he tohatoha āhua whānui i roto i to tatou whenua, na reira he rerekētanga i roto i te āhua o te kiripaka kirikiri, i roto i te purenga o te kiripaka kirikiri me hoki ki te raruraru motuhake motuhake. tātaritanga, whakawhanake i te tukanga purenga kiripaka kiripaka.
