Use powdered calcium chloride _ _ Hang a Chemical Technology

At the time of purchase of calcium chloride, calcium chloride, manufacturers are marked purity is how much, but true whether labeled purity calcium chloride purity like it, let's tell you about the eligibility of a method to detect calcium chloride: Because sodium chloride, calcium sulfate, potassium chloride, although these impurities are soluble in water, but due to common ion effect of calcium chloride, leaving a high concentration of these salts in the solubility of the calcium chloride solution is very small, when the concentration of calcium chloride These salts are very hardly soluble, so dubbed 1: 1 salt water to dissolve the white precipitate was observed to the number. The more white insolubles lower purity, high purity calcium chloride is not white insolubles. Simultaneous detection of the supernatant at halide, halogen and high water sophomore who powdered calcium chloride, and vice versa. Calcium chloride dihydrate now varying quality on the market use powdered calcium chloride, calcium chloride, different quality prices vary greatly, what we need is not the product of calcium chloride impurities because the average calcium chloride sodium chloride, calcium sulfate, potassium chloride does not occur with calcium oxide is reacted. That impurities mixed salts of these products for you to play the harmful effects, mainly due to the role of these impurities leaving your product a "brine back" phenomenon. To tell you about the three requirements for calcium chloride standard equipment: 1. logo: have a clear sign of powdered calcium chloride dihydrate role of calcium chloride bags, and the flag content should contain the name of the manufacturer, the product name, registered trademark, grade, weight and safety notices and so on. Within 2 bags: use of calcium chloride in the bag should be polyethylene plastic film bag, seal the bag inside the way the choice of adhesive, Pooh Long rope, artificial Zhakou several ways. 3. packaging bags: plastic bags packaging bags should be, and the net weight of each bag is 50kg. When the sealed outer bag to more than 3cm in distance at the side pocket hem, at a distance of more than 1.5cm at the edge of the bag with rope Vinalon line equivalent quality seam, stitch seam should ensure proper uniform, neat stitches, no slatted other phenomena.
