六偏磷酸鈉 SODIUM HEXAMETAPHOSPHATE
一、化學(xué)名：六偏磷酸鈉
二、分子式：(NaPO3) 6
三、分子量：611.77
四、CAS：10124-56-8
五、性狀：無色透明玻璃片狀或流沙狀結(jié)晶粉末。易溶于水，不溶于乙醇及乙醚等有機(jī)溶劑。吸濕性很強(qiáng)，露置于空氣中能逐漸吸收水分而呈粘膠狀物。水溶液可與鈣、鎂等金屬離子生成可溶性絡(luò)合物。熔點(diǎn)616℃（分解），相對密度2.484g/cm3（20℃）。
六、用途：用作品質(zhì)改良劑、pH調(diào)解劑、金屬離子螯合劑、粘結(jié)劑和膨脹劑。在豆類、果蔬罐頭、豆沙餡料中能穩(wěn)定天然色素，保護(hù)食品色澤；在肉類罐頭中可使脂肪乳化，保持質(zhì)地均勻；用于肉類罐頭和肉制品可提高持水性，能防止脂肪變質(zhì)。加入啤酒中，能澄清酒液，防止混濁。是優(yōu)良的水質(zhì)無沉淀的軟水劑。
七、包裝：內(nèi)襯聚乙烯塑料袋，外套塑料編織袋，每袋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。

1、Chemical Name: SODIUM HEXAMETAPHOSPHATE
2、Molecular Formula : (NaPO3) 6
3、Molecular Weight: 611.77
4、CAS: 10124-56-8
5、Character: It is colorless transparent flake like foliated glass or float sand crystalline powder. It’s easily soluble in water, insoluble in organic solvent such as ethanol and ether. It absorbs moisture easily. When put in air, it could slowly absorb moisture and turn into viscose-like substance. Aqueous solution could react with metal ions such as Calcium, Magnesium, to form complex compound. Melting point is 616℃ (decompose). Relative density is 2.484g/cm3（20℃）.
6、Usage: It is used as quality improver, pH regulator, chelating agent, binder and swelling agent. It’s also used to stabilize natural pigment in beans, fruit vegetable cans and bean stuffing; to emulsify fat in canned meat. For canned food and meat product, it could improve their water holding capacity and prevent fat from corrosion. It may clarify beer to avoid turbidity. It’s an excellent water softener without precipitation.
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 avoid damage. Furthermore, it must be stored separately from poisonous substances.
