Kalipuna hydroxide: ka waiwai a me ka noi

Ca (OH) 2 - ka kalipuna hydroxide (mai Roma pōhaku hydroxide), ia mea he like Nine Inch. Ia mea ma kona loa ke ano maoli ua noʻonoʻo i ka ikaika kumu. Ua ho melkokrupinchaty yellowish ka pauka a me colorless nā pōaka. Hiki i ka decompose ka wā pii kai iki ana, ka mea, ua hookuu ia me ka hopena o ke kalipuna'okesaside. He poorly wailana i loko o ka wai. An koʻana koko pāʻoihana o ke kalipuna hydroxide ma luna o lākou Nine Inch waiwai o ka awelika manawa. Ma ke alo o ke hooheheeia ke hookuu aku hydrogen, a ua ike ma ka pahū kinoea.

Kalipuna hydroxide ka wā i ke kino ma ka 'ai, inu a ma inhalation o ka aerosol hiki e paka i loko o'aʻaʻa, a, e loaa i loko o ia mau mea. At maʻamau mehana ea 20-22 degere substance ua 'ano ole evaporate, akā, konaʻehu (particles) e e weliweli i ka ola. Noho ma luna o kaʻili, i ka ÷ naehana hanu'āpana mucous membranes a me na maka, o ka kalipuna hydroxide mea o keʻano ukiuki, i corrosive. Hooloihi ae i hui 'ana me ka ili hiki i dermatitis. Ua e loli hiki no hoi akemāmā'aʻaʻa ma kōnea i ka kalipuna hydroxide (particles).

Kēia Nine Inch i huiia i na mea he nui AICIeOEOI inoa, e like me slaked Lime (ka mea, ua hoomakaukauia ia e slaking kalipuna'okesaside me ka akaka ka wai) Lime wai (mea he maopopo koʻana koko pāʻoihana). Other inoa: pushonka (kalipuna hydroxide i loko o ka palapala o ka lepo maloʻo), a me ka waiu o ka Lime (paʻa kūhohonu loa koʻana koko slurry). Pinepine, i ka quicklime a Lime ua i haawi ia ia e like me kalipuna'okesaside.

Kalipuna hydroxide, Nine Inch waiwai a i manaoiaʻano pākīkē me ka mahalo i nā waiwai, i hoomakaukauia ma ka slaking ka Lime, a laila, ma ka AaOIeIOUIeXAOAaIN (Nine Inch naoh) o ke kalipuna'okesaside a me ka wai. Schematically, ka naoh Ua like penei:

CaO + H2O = Ca (OH) 2

I ka loaa koʻana koko kona'ākilikai naoh meakino ano. Like a pau typical hydroxide, kalipuna hydroxide reacts me:

1.'okanikaʻole nāʻakika e lilo kalipuna paʻakai o typical

H2SO4 + Ca (OH) 2 = CaSO4 + 2H2O

2. Ke i carbon dioxide i ua mea hoʻoheheʻe i loko o ka wai, no laila, i ke koʻana koko pāʻoihana i ao loa koke ma ka lewa, ho okumu i ke keʻokeʻo insoluble precipitate - paʻapuna

CO2 + Ca (OH) 2 = CaCO3 + H2O

3. Ka kalapona monoxide ma ka hoʻoulu i ka mahana i 400 kekelē Kelekia ma

CO (, t °) + Ca (OH) 2 = CaCO3 + h2

4. paʻakai, i kūpono ai keʻokeʻo precipitate - kalipuna sulufahate

Na2SO3 + Ca (OH) 2 = CaSO3 + 2NaOH

E ho ohana i ke kalipuna hydroxide ka loa mahalo. He oiaio, kela mea keia mea ua ike no ia i ka Lime lapaau ana pā pālahalaha, laau nui ilpko o, e like me kona hoʻohana like me ka ke keʻena o ka hale wili. Ka hoʻohana o ke kalipuna hydroxide i loko o ka hana, ua hoikeia mai ka wa kahiko. I kona manawa haku mele 'ana nā stucco mea waiwai Lime pōhaku lepo a me ka pōhaku puna, na mele o i mea kokoke'ālike me ka puna. Ka papa likeʻole o loko o ke ano o ko lakou hoomakaukau ana o kēia mau ia pāʻoihana.

Kalipuna hydroxide ua hoʻohana 'ia e hoopalupalu mai i ka hana i ka wai, no ka hana o ka Hekikai, Lime'okanikaʻole fertilizers causticization o ka paʻakai kalepona, a me ka potasiuma. Nō hoʻi, i kēia waiwai mea paʻa mau no ka tanning i loko o ka lole hana, i loko o ka makaukau o kekahi mau hui o ka kalipuna like hoʻi me ka neutralization oʻakika pāʻoihana a me ka neoneo wai me. Ma kona kumu o ka loaa ana ke alohaʻakika.

Kalipuna hydroxide Ua loaʻa kona palapala noi i loko o ka meaʻai hana, kahi e ua maikaʻi ike me he ai mea hoʻonui E526, ua hoʻohana 'ia e like me kaʻakika mea hoʻokonukonu, thickener a me ka hardener. Ma ke kō hana, ka mea, ua hoʻohana 'ia no ka leaching o ka molasses.

I keʻena hoʻokolohua ho okolohua a me ka h ÷ ike Lime wai Ua paʻa mau anakahi ka loaʻaʻana o ke kalapona'okikene lua i loko o Nine Inch reactions. Ka waiū o ka Lime lapaau ana mea kanu, e kaua mai, a me pests.
