Hoʻohana
ʻO ka zinc sulfate, me ke ʻano kemika ZnSO4, he kristal rhombic kala ʻole me ka nui o 3.54. Hoʻoheheʻe ia i loko o ka zinc oxide ke hoʻomehana ʻia i 770 ℃. ʻO ka hydrate he zinc sulfate monohydrate ZnSO4·H2O, he kristal pauka keʻokeʻo me ka nui o 3.31. Ke hoʻomehana ʻia i 280 ℃, nalowale ka wai a lilo i anhydrous. ʻO ka zinc sulfate hexahydrate ZnSO4·6H2O he kristal monoclinic a tetragonal kala ʻole me ka nui o 2.07. Ke hoʻomehana ʻia i 70 ℃, nalowale ia i 5 mau molekala wai o ka crystallization e lilo i zinc sulfate monohydrate. ʻO ka zinc sulfate heptahydrate, ZnSO4·7H2O, i ʻike nui ʻia ʻo "alum" a i ʻole "zinc alum", ʻo ia ke ʻano maʻamau. He kristal rhombic kala ʻole a i ʻole ka pauka kristal keʻokeʻo. Hoʻopuka mālie ia i ka ea maloʻo, me ka nui o 1.96. Ma 39 ℃, nalowale hoʻokahi mole o ka wai crystalline e lilo i zinc sulfate hexahydrate. He mea hoʻoheheʻe loa ka zinc sulfate i ka wai, a he waikawa nāwaliwali kona hopena wai. Hiki iā ia ke hoʻoheheʻe i loko o ka glycerol a he mea hoʻoheheʻe iki i loko o ka ethanol. Hoʻokumu ia i kahi paʻakai pālua o ke ʻano ZnSO4·K2SO4·6H2O me ka potassium sulfate. Ke hoʻoheheʻe ʻia ka zinc metala a i ʻole ka zinc oxide i loko o ka waikawa sulfuric dilute a hoʻopaʻa ʻia a hoʻopaʻa ʻia ma 30 ℃, hiki ke loaʻa ka heptahydrate zinc sulfate. A laila, ma ka hoʻokiʻekiʻe ʻana i ka mahana, hiki ke loaʻa nā ʻano zinc sulfate like ʻole. Hoʻohana ʻia ia ma ke ʻano he mordant i ka hoʻoluʻu ʻana a me ka paʻi ʻana, kahi mea mālama lāʻau, kahi mea hoʻokeʻokeʻo i ka hana pepa, a hoʻohana ʻia hoʻi i ka lāʻau lapaʻau, nā olonā artificial, electrolysis, electroplating, pesticides a me ka hana ʻana o nā paʻakai zinc, a pēlā aku.
ʻO ka zinc sulfate ZnSO4, i ʻike ʻia hoʻi he alum a i ʻole zinc alum, he kristal orthorhombic kala ʻole a keʻokeʻo paha i ka mahana o ka lumi. Loaʻa iā ia nā waiwai astringent, hoʻoheheʻe nui ʻia i ka wai, a ʻo kona hopena wai he waikawa. Hoʻoheheʻe iki ʻia i loko o ka ethanol a me ka glycerol. ʻAʻole e melemele ka zinc sulfate maʻemaʻe ke mālama ʻia i ka lewa no ka manawa lōʻihi. Ke waiho ʻia i ka ea maloʻo, nalowale ka wai a lilo i pauka keʻokeʻo. Aia nā hydrates like ʻole: ʻo ka hydrate paʻa i ke kaulike me ka wai i loko o ka pae o 0-39 ℃ ʻo ia ka zinc sulfate heptahydrate; i loko o 39-60 ℃, he zinc sulfate hexahydrate; a i loko o 60-100 ℃, he zinc sulfate monohydrate. Ke hoʻomehana ʻia i 280 ℃, nalowale loa nā hydrates āpau i ko lākou wai crystalline. Ma 680 ℃, hoʻoheheʻe lākou i loko o ka zinc oxysulfate. Ma luna o 750 ℃, hoʻoheheʻe hou lākou. ʻO ka hope, ma kahi o 930 ℃, hoʻoheheʻe lākou i loko o ka zinc oxide a me ka sulfur trioxide. Hoʻokumu ʻo ZnSO4·7H2O a me MSO4·7H2O (M = Mg, Fe, Mn, Co, Ni) i nā kristal i hui pū ʻia i loko o kahi pae i koho ʻia.
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
