4. Packing and storage                                                                                       

Packing: Calcium Hypochlorite is packed in 10kgs, 25kgs, 40kgs, 45kgs, 50kgs plastic drums or 50kgs iron drums with PVC plastic bag.

Storage: Dry, ventilated, moisture proof. Calcium Hypochlorite is a strong oxidant. Should be stored in dry, cool and ventilated place; avoid insulation, fire and heat; do keep it from mixing with organic substances, acids, oil or reducing agents. when the package is broken and scatters, fast collecting and airproofing the product in time, if the skin be touched with it , fast washing with diluted ammonia solution.

Fire-extinguishing:

Put out a fire with yellow sand, carbon dioxide and foam, don’t use ordinary vitriol fire extinguisher.


碳酸钙

轻质碳酸钙又称沉淀碳酸钙,简称轻钙,分子式CaCO ,分子量100.09。轻钙是将石灰石等原料煅烧生成石灰(主要成分为氧化钙)和二氧化碳,再加水消化石灰生成石灰乳(主要成分为氢氧化钙),然后再通入二氧化碳碳化石灰乳生成碳酸钙沉淀,最后经脱水、干燥和粉碎而制得。或者先用碳酸钠和氯化钙进行复分解反应生成碳酸钙沉淀,然后经脱水、干燥和粉碎而制得。由于轻质碳酸钙的沉降体积(2.4-2.8mL/g)比重质碳酸钙的沉降体积(1.1-1.4mL/g)大,所以称之为轻质碳酸钙。

轻钙性质:白色粉末,无味,无臭,比重约2.71。在825~896.6℃分解,熔点1339℃。有无定形和结晶形两种形态,结晶形中又可分为斜方晶系和六方晶系,呈柱状或菱形。难溶于水和醇。溶于酸,同时放出二氧化碳,呈放热反应;也溶于氯化铵溶液中;在空气中稳定,有轻微的吸潮能力。

轻钙用途:

可用作橡胶、塑料、造纸、涂料和油墨等行业的填料。广泛用于有机合成、冶金、玻璃和石棉等生产中。还可用作工业废水的中和剂、胃与十二指肠溃疡病的制酸剂、酸中毒的解毒剂、含SO废气中的SO消除剂、乳牛饲料添加剂和油毛毡的防粘剂。也可用作牙粉、牙膏及其它化妆品的原料。

相对分子量 100.09重质碳酸钙性质 白色粉末,无色、无味。在空气中稳定。几乎不溶于水,不溶于醇。遇稀醋酸、稀盐酸、稀硝酸发生泡沸,并溶解。加热到898℃开始分解为氧化钙和二氧化碳。 重质碳酸钙,简称重钙,是由天然碳酸盐矿物如方解石、大理石、石灰石磨碎而成。是常用的粉状无机填料,具有化学纯度高、惰性大、不易化学反应、热稳定性好、在400℃以下不会分解、白度高、吸油率低、折光率低、质软、干燥、不含结晶水、硬度低磨耗值小、无毒、无味、无臭、分散性好等优点。

英文名:calcium carbonate

分子式 CaCO3

可根据需要提供不同粒度要求的普通重钙粉、超细重质碳酸钙、湿法研磨超细碳酸钙、超细表面改性重质碳酸钙。

重质碳酸钙的应用:

"重钙"就是方解石粉,是"重质碳酸钙"的简称,主要成分是重质碳酸钙,重质碳酸钙也简称为"重钙",通常用作填料,广泛用于人造地砖、橡胶、塑料、造纸、涂料、油漆、油墨、电缆、建筑用品、食品、医药、纺织、饲料、牙膏等日用化工行业,作填充剂起到增加产品的体积,降低生产成本。
