食品級硫酸銅工廠直售 質(zhì)量上等

硫酸銅 COPPER SULFATE 一、化學(xué)名：硫酸銅 二、分子式：CuSO4·5H2O 三、分子量：249.7 四、：7758-99-8 五、性狀：深藍(lán)色三斜晶體或藍(lán)色結(jié)晶性顆粒或粉末。具有令人厭惡的金屬味。干燥空氣中緩慢風(fēng)化。相對密度2.284。高于150℃形成白色易吸水的無水硫酸銅。于650℃分解成氧化銅。易溶于水（26.3g/100g，20℃），呈酸性，0.1mol/L水溶液的pH值為4.17（15℃）。易溶于甘油，溶于稀，不溶于無水。 六、用途：營養(yǎng)增補(bǔ)劑、抗微生物劑、固化劑、加工助劑。 七、包裝：內(nèi)襯聚乙烯塑料袋，外套復(fù)合塑料編織袋包裝，每袋凈重25kg。。 八、貯存與運(yùn)輸：本品應(yīng)貯存在干燥通風(fēng)清潔的庫房中，裝載運(yùn)輸時要輕裝輕放，防止包裝破損，防止受潮、受熱，運(yùn)輸過程中防止雨淋受潮，應(yīng)與有毒物品隔離。 質(zhì)量指標(biāo) Specification GB29210-2012 FCC VII 含量（CuSO4·5H2O），w/% Content (CuSO4·5H2O), w/% 98.0-102.0 98.0-102.0 不沉淀物, w/% ≤ Substances Not Precipitated by Hydrogen Sulfide,w/% ≤ 0.3 0.3 鐵（Fe），w/% ≤ Iron (Fe), w/% ≤ 0.01 0.01 鉛（Pb），mg/kg ≤ Lead (Pb),mg/kg ≤ 4 4 （As），mg/kg ≤ Arsenic (As),mg/kg ≤ 3 ———— 1、Chemical Name: Copper Sulfate 2、Molecular Formula: CuSO4·5H2O 3、Molecular Weight: 249.7 4、: 7758-98-7 5、Character: It’s dark blue triclinic crystal or blue crystalline powder or granule. It smells like nasty metal. It effloresces slowly in dry air. Relative density is 2.284. When above 150℃, it loses water and form Anhydrous Copper Sulfate which absorbs water easily. It’s soluble in water freely and aqueous solution is acidic. pH value of 0.1mol/L aqueous solution is 4.17（15℃）. It’s soluble in glycerol freely and dilute ethanol but insoluble in pure ethanol. 6、Usage: It is used as nutritional supplement, antimicrobial agent, firming agent and processing aid. 7、Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg. 8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to oid damage. Furthermore, it must be stored separately from poisonous substances.
