ʻO ke one quartz i holoi ʻia e ka waikawa

Hoʻopili kikoʻī ʻia ke kaʻina hana ʻohi ʻana i ke one quartz

I ke koho ʻana i ke one quartz i hoʻomaʻemaʻe ʻia a me ke one quartz maʻemaʻe kiʻekiʻe, paʻakikī ke hoʻokō i nā koi o nā ʻano hana hoʻomaikaʻi maʻamau, ʻoi aku hoʻi no ke kiʻi ʻoniʻoni hao ma ka ʻili o ke one quartz a me nā haumia hao i loko o nā māwae.I mea e hoʻomaikaʻi maikaʻi ai i ka maikaʻi a me ka hua o ka hoʻomaʻemaʻe ʻana i ke one quartz, i hui pū ʻia me nā ʻano o ke one quartz insoluble i ka waikawa a hiki ke hoʻoheheʻe iki ʻia i ka hopena KOH, ua lilo ke ʻano leaching acid i mea pono e mālama ai i ke one quartz.

ʻO ka mālama ʻana i ke one quartz pickling ka mālama ʻana i ke one quartz me ka waika hydrochloric, sulfuric acid, oxalic acid a i ʻole hydrofluoric acid e hoʻoheheʻe i ka hao.

ʻO ke kaʻina hana maʻamau o ka pickling one quartz

Hoʻohālikelike au i ka wai waika

Pono e hana ʻia ke one me 7-9% oxalic acid, 1-3% hydrofluoric acid a me 90% wai hui;Pono 2-3.5 tons o ka wai, ina e hana hou ia ka wai, a laila, pono 0.1 tons o ka wai e hoʻomaʻemaʻe i hoʻokahi tona o ke one, i loko o ka hana hoʻomaʻemaʻe one, e inevitably lawe mai i ka hapa nui o ke one;ʻO ka mālama ʻana i ke one quartz pickling ka mālama ʻana i ke one quartz me ka waika hydrochloric, sulfuric acid, oxalic acid a i ʻole hydrofluoric acid e hoʻoheheʻe i ka hao.

Ⅱ ʻO ka hui ʻana o ka pickling

Hoʻokomo ʻia ka solution pickling i loko o ka pahu pickling a hoʻohui ʻia e like me ka nui o ka waika hydrochloric ma kahi o 5% o ke kaumaha o ke one e hōʻoia i ka pulu ʻana o ke one quartz i loko o ka hopena pickling a ʻo ka waika hydrochloric ma kahi o 5% o ka. kaumaha one.

Ⅲ Ke one quartz holoi ʻakika
① ʻO ka manawa no ke one quartz e hoʻonā i ka hopena pickling ma ke ʻano he 3-5 mau hola, ʻo ka pono kikoʻī e hoʻonui a hoʻemi paha i ka manawa hoʻoluʻu e like me ka ʻili melemele o ke one quartz, a i ʻole ka hopena pickling a me ke one quartz hiki ke hoʻoulu ʻia no kekahi manawa. ʻO ka manawa, a ma hope o ka hoʻohana ʻana i nā mea hoʻomehana e wela ai ka hopena i kahi mahana, hiki ke hōʻemi i ka manawa pickling.

② ʻO ka hoʻohana ʻana i ka waika oxalic a me ka alum ʻōmaʻomaʻo e like me ka hoʻohaʻahaʻa ʻana i ka lāʻau pickling agent hiki ke hoʻomaikaʻi i ka solubility o ka hao, ma ka huli ʻana, ka wai, ka waikawa oxalic, ka alum ʻōmaʻomaʻo e like me ka māhele o ka hopena i kekahi mahana, ke one quartz a me ka hopena e like me. me kahi hapa o ka hui ʻana, ka hoʻoulu ʻana, ka mālama ʻana no kekahi mau minuke, kānana ʻia ka hopena a mālama ʻia ma hope o ka hoʻihoʻi ʻana.

③ ʻO ka mālama ʻana i ka waika hydrofluoric: Maikaʻi ka hopena inā hoʻohana wale ʻia ka lāʻau hydrofluoric acid, akā ʻoi aku ka kiʻekiʻe.Ke kaʻana like me ka sodium dithionite, hiki ke hoʻohana ʻia nā haʻahaʻa haʻahaʻa o ka waika hydrofluoric.

Hoʻohui ʻia kekahi ʻano o ka waika hydrochloric a me ka waika hydrofluoric i loko o ka slurry one quartz i ka manawa like e like me ka nui;Hiki ke mālama ʻia me ka waika hydrochloric solution ma mua, holoi ʻia a laila mālama ʻia me ka waika hydrofluoric, mālama ʻia i ka mahana wela no 2-3 mau hola, a laila kānana a hoʻomaʻemaʻe ʻia.

Nānā:

Inā hoʻohana ʻia ka waika hydrofluoric e hoʻokahe i ke one quartz, ʻoi aku ka paʻakikī o ka hopena.Ma waho aʻe o ka hoʻoheheʻe ʻana o ka hao i loko o ka media acidic, hiki i ka HF ke hana pū me ka quartz ponoʻī e hoʻoheheʻe iā SiO2 a me nā silicates ʻē aʻe o kahi mānoanoa ma ka ʻili.

Eia naʻe, ʻoi aku ka maikaʻi o kēia no ka hoʻomaʻemaʻe ʻana i ka ʻili o ke one quartz a me ka hoʻopau ʻana i ka hao a me nā mea haumia ʻē aʻe, no laila maikaʻi ka waika hydrofluoric no ka leaching acid o ka quartz.Eia nō naʻe, he mea ʻawaʻawa a ʻino loa ka HF, no laila, pono i ka wai hoʻoheheʻe wai waika i ka mālama kūikawā.

ʻO ka hoʻihoʻi ʻana a me ka deacidification o ka waika

Holoi i ke one quartz acid i holoi ʻia me ka wai 2-3 mau manawa, a laila neutralize me 0.05% -0.5% o ka sodium hydroxide (caustic soda) alkaline solution, a ʻo ka manawa neutralization ma kahi o 30-60 mau minuke, a e hōʻoia i ka quartz āpau. hoʻokaʻawale ʻia ke one ma kahi.I ka hiki ʻana o ka pH i ka alkaline, hiki iā ʻoe ke hoʻokuʻu i ka lye a holoi i nā manawa 1-2 a hiki i ka pH kū ʻole.

Ⅴ Ke one quartz maloʻo

Pono e hoʻokahe ʻia ke one quartz i ka wai ma hope o ka hemo ʻana o ka waikawa, a laila e hoʻomaloʻo ʻia ke one quartz i loko o nā mea hoʻomaloʻo.

Ⅵ ka nānā ʻana, ke koho kala a me ka hoʻopili ʻana, etc.

ʻO ka mea ma luna nei ke kaʻina hana o ka quartz sand pickling a me ka leaching treatment process, quartz sand ore kahi ākea ākea i ko mākou ʻāina, no laila aia nā ʻokoʻa i ke ʻano o ke one quartz, i ka hoʻomaʻemaʻe ʻana i ke one quartz pono pū kekahi pilikia kikoʻī. ka nānā ʻana, hoʻomohala i kahi kaʻina hoʻomaʻemaʻe one quartz kūpono.
