Kalipuna sulufahate. hōʻikeʻano

Ma Hoikehonua,'okanikaʻole kemika nui paʻakai Mea Maluna a me ka waiwai o ka AaOIeIOUIeXAOAaIN oihana mua a me kā lākou mea a pau e hiki i huiʻia. Aia mau waiwai i, i waena o 'ē aʻe kūlana' he kupaianaha wahi. Oia i huiʻia i loko o pau e e haawiia kalipuna sulufahate. Haʻilula waiwai CaSO4.

KŘpa a nui hoʻokomo kālā o kēia hui i loko o ka pńpa ae kona hoʻohana like me ka maka mea i loko o ka makaukau o kekahi mau mea. Ke kūpono i nā hiki ke ana hoʻohana i kūkuluʻia, lapaʻau, a me ka like.

loaʻa mea pōhaku hoʻokomo kālā me he haku mele 'ana o CaSO4 2 H2O Ma maoli ana. Kalipuna sulufahate ua i loaʻa i loko o ke kai (ma kahi o 1800 000 nā kana no cubic mika) a me ka wai.

CaSO4 anhydride mea he keʻokeʻo ka pauka nuʻa o 2.90-2.99 nā huna no cubic kenimika. Hui 'Imi absorbs ona mau mai o ka lewa. No ka mea, o keia waiwai, a me ka kalipuna sulufahate hoʻohana like me ka ka maloʻoʻana hope.

Ma mahana tausani,ʻehā haneri a me kanalima nā degere he waiwai ka heheʻe, a decomposes. Ke solubility o ka waiwai ua hoʻokāʻoi 'ia ma ke alo o HCl, HNO3, NaCl, MgCl2. Kalipuna sulufahate reacts me ka sulfuricʻakika ua hoemi sintering me ka kalapona ka wā.

I loko o ka wai pu me MgSO4 a me MgCl2, CaSO4 rigidity haawi ia i ka ikaika. Nine i hoopalupaluia, loli mea hiki i na reagents. Ka ho'ēmiʻana o ka paʻakikī o ka wai ma muli o ka hoʻokomo 'ia' o ka 'ona ka waiwai o kona anions.

lawe e hoopalupalu ana o ka wai, ua hoi mai ma ion mail. Kēia papa hana ua ma muli o ka hiki ana o kekahi kemikala, a ma kona ano maoli ion poe kuai moni - kiʻekiʻe-hakakino i huiʻia - āina radicals komo i loko o ko lākou haku mele 'ana, ma ka Ion makana ma ka pāʻoihana. Like ion poe kuai moni pinepine hana aluminosilicates (Na2 [Al2Si2O8] ∙ nH2O, no ka laʻana).

Hydrate me ka haku mele 2CaSO4 H2O - ipu (puhi gypsum) - hoʻohana 'ia i loko o ka hana o cementitious mea. Kēia mau waiwai ho i ka pulverulent hui, a i ka wā paʻipaʻiʻia me ka wai ano ea mua, a me ka a laila solidifying i loko o ka paa kino kaumaha. E hoomakaukau ai kaʻina ua lawe mai i ipu gypsum calcination ma lalo o ka aoao o ka mahana, mai hoʻokahi haneri a me kanalima i hoʻokahi haneri a me kanahiku degere. Keia waiwai ua hoʻohana 'ia i loko o ka hana o ka paku Panel a me ka papa, ka hopena he' ikamu, e like me ia ma ka manaʻo o ka puna.

Calcination ma lalo o ka aoao o ka mahana,ʻelua haneri a oi ma mua o nā degere he hiki aku ai i ke kahua o ka wailana ano o ke kalipuna sulufahate anhydrous, ma ke ana wela i oi aku mamua o elima haneri degere - insoluble palapala. I ka la mahope haalele i kona hiki e paʻa i ka wai no ia mea, hiki ole ke ia me ka mea hoʻopaʻa.

Natural gypsum hiki ke hoʻohana i kekahi wahi ho mea i loko o ka makaukau o ka lepo pipili, a sulfuricʻakika ma ka hui hana.

Natural kalipuna sulphate hiki ke hoʻohana pū me ka desiccant i loko o ka Ikepili o ke aloha i huiʻia. Ke anhydrous i huiia mea hiki ke ka hoʻokemu ona mau 6,6% o ka nui o ke kaumaha. Kalipuna sulufahate i hoʻohana ua i loko o ka hana o ka hō'īpale mea.
