Kagwiritsidwe Ntchito

Zinc sulfate, yokhala ndi formula ya mankhwala ya ZnSO4, ndi kristalo yopanda mtundu wa rhombic yokhala ndi kachulukidwe koyerekeza ka 3.54. Imawola kukhala zinc oxide ikatenthedwa kufika pa 770℃. Hydrate ndi zinc sulfate monohydrate ZnSO4·H2O, kristalo yoyera ya ufa yokhala ndi kachulukidwe koyerekeza ka 3.31. Ikatenthedwa kufika pa 280℃, imataya madzi ndipo imakhala yopanda madzi. Zinc sulfate hexahydrate ZnSO4·6H2O ndi kristalo yopanda mtundu wa monoclinic kapena tetragonal yokhala ndi kachulukidwe koyerekeza ka 2.07. Ikatenthedwa kufika pa 70℃, imataya mamolekyu 5 a madzi a crystallization kukhala zinc sulfate monohydrate. Zinc sulfate heptahydrate, ZnSO4·7H2O, yomwe imadziwika kuti "alum" kapena "zinc alum", ndiyo mtundu wofala kwambiri. Ndi kristalo yopanda mtundu wa rhombic kapena ufa woyera wa kristalo. Pang'onopang'ono imatuluka mumlengalenga wouma, yokhala ndi kachulukidwe koyerekeza ka 1.96. Pa kutentha kwa 39℃, imataya molekyu imodzi ya madzi a crystalline kuti ikhale zinc sulfate hexahydrate. Zinc sulfate imasungunuka kwambiri m'madzi, ndipo madzi ake amakhala ndi asidi pang'ono. Imatha kusungunuka mu glycerol ndipo imasungunuka pang'ono mu ethanol. Imapanga mchere wawiri wa mtundu wa ZnSO4·K2SO4·6H2O wokhala ndi potassium sulfate. Zinc kapena zinc oxide yachitsulo ikasungunuka mu diluted sulfuric acid ndikuyikira ndi kupangika crystallized pa 30℃, heptahydrate zinc sulfate ingapezeke. Kenako, pokweza kutentha, mitundu ina yosiyanasiyana ya zinc sulfate ingapezeke. Imagwiritsidwa ntchito ngati mordant pakupaka utoto ndi kusindikiza, chosungira matabwa, choyeretsera bleach popanga mapepala, ndipo imagwiritsidwanso ntchito mu mankhwala, ulusi wopangira, electrolysis, electroplating, mankhwala ophera tizilombo komanso kupanga mchere wa zinc, ndi zina zotero.

Zinc sulfate ZnSO4, yomwe imadziwikanso kuti alum kapena zinc alum, ndi kristalo kapena ufa wopanda mtundu kapena woyera wa orthorhombic pa kutentha kwa chipinda. Ili ndi mphamvu zolimbitsa thupi, imasungunuka kwambiri m'madzi, ndipo yankho lake lamadzi ndi acidic. Imasungunuka pang'ono mu ethanol ndi glycerol. Zinc sulfate yoyera siimasintha kukhala yachikasu ikasungidwa mumlengalenga kwa nthawi yayitali. Ikayikidwa mumlengalenga wouma, imataya madzi ndipo imakhala ufa woyera. Pali ma hydrate osiyanasiyana: hydrate yokhazikika yomwe imafanana ndi madzi mkati mwa 0-39℃ ndi zinc sulfate heptahydrate; mkati mwa 39-60℃, ndi zinc sulfate hexahydrate; ndipo mkati mwa 60-100℃, ndi zinc sulfate monohydrate. Ikatenthedwa kufika pa 280℃, ma hydrate onse amataya madzi awo a crystalline kwathunthu. Pa 680℃, amawola kukhala zinc oxysulfate. Pamwamba pa 750℃, amawolanso. Pomaliza, pafupifupi 930℃, amawola kukhala zinc oxide ndi sulfure trioxide. ZnSO4·7H2O ndi MSO4·7H2O (M = Mg, Fe, Mn, Co, Ni) amapanga makhiristo osakanikirana mkati mwa mtundu winawake.

Kulongedza ndi Kutumiza

25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga

Sungani ndi kusunga

Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
