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 taraihia te otinga ka 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 maataa i te tuatahi, ka horoi katahi ka rongoa ki te waikawa hydrofluoric, ka rongoa 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 Whakaora me te whakakore waikawa

Horoihia te kirikiri kiripaka kua horoia waikawa ki te wai 2-3 wa, katahi ka whakakorehia 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 tetahi tukanga purenga kiripaka pai.
