【氯化钙简介】

      氯化钙（calcium chloride）是一种由氯元素和钙元素构成的盐，化学式为CaCl2。它是典型的离子型卤化物，室温下为白色固体。它常见应用制冷设备所用的盐水、道路融冰剂和干燥剂。因为它在空气中易吸收水分发生潮解，所以无水氯化钙必须在容器中密封储藏。氯化钙及其水合物和溶液在食品制造、建筑材料、医学和生物学等多个方面均有重要的应用价值。工业级一级、二级主要用于工业生产、净水剂、上浆剂、脱水剂、干燥剂、除尘剂、土质改良剂、防冻剂、冷冻剂等。

      液体氯化钙的含量：30%-36%等。氯化钙溶液是致冷工业中重要的冷冻剂。在使用过程中，会因吸收空气中的水分而使其浓度降低。尤其是在开式系统中。为了防止氯化钙的浓度降低，引起凝固点温度升高，故必须定期用比重计测定氯化钙的比重。若浓度降低时，应补充，以保持在适当的浓度。氯化钙的凝固温度随浓度而变，当溶液浓度为29.9%时，氯化钙盐水的凝固温度为-55℃；氯化钙水溶液对设备有腐蚀性，使用时应该注意。其溶液在基因工程中可用来制作感受态细胞。

Calcium chloride, calcium chloride) is a kind of composed of chlorine and calcium salt, chemical formula for CaCl2. It is a typical ionic halide, white solid at room temperature. It commonly used refrigeration equipment used in the salt water, roads, melting agent and desiccant. Because it is liable to absorb moisture in the air deliquescence, so anhydrous calcium chloride must be sealed storage in the container. Calcium chloride and hydrate and solution in the food manufacturing, building materials, medicine and biology, and other aspects have important application value. Industrial-grade first class and second class is mainly used in industrial production, water purifier, sizing agent, dehydrating agent, desiccant, dust removal agent, soil conditioner, antifreeze, coolant, etc.

Liquid calcium chloride content: 30% - 36%, etc. Calcium chloride solution is an important of refrigerant in refrigeration industry. In use process, will absorb the moisture in the air and reduce its concentration. Especially in the open system. In order to prevent the concentration of calcium chloride to reduce, cause the freezing point temperature, it should be the proportion of calcium chloride was determined by hydrometer on a regular basis. 

【氯化钙分类】

      氯化钙是一种无机盐，按形态可分为固体和液体两种。液体氯化钙是一种无色透明的水溶液。固体氯化钙是一种白色结晶体，按形状的不同又可分为片状、粒状、球粒状及粉状，同时由于固体氯化钙所含结晶水的不同，通常情况下又将固体氯化钙分为二水氯化钙（74%-80%）和无水氯化钙（94%-98%）。

Calcium chloride is an inorganic salt, according to the form can be divided into two kinds of solid and liquid. Liquid calcium chloride is a colorless transparent solution. Solid calcium chloride is a white crystal, according to the different shape and can be divided into flake, granular, granular and powdered, at the same time, due to the different solid calcium chloride crystallization water contained normally and solid calcium chloride can be divided into two water calcium chloride (74% 80%) and anhydrous calcium chloride (94% 98%).

【氯化钙用途】

      无机工业用作制造金属钙、氯化钡、各种钙盐（如磷酸钙等）的原料。建筑工业用作防冻剂，以加速混凝土硬化和增加建筑砂浆的耐寒能力。微生物工业用作单倍体育种的培养基。分析化学中用于测定钢铁含碳量、全血葡萄溶、血清无机磷和血清碱性磷酸酶的活力等。用作铝镁冶金的保护剂、精炼剂。此外，还用作织物的防火剂、海港的消雾剂、路面的集尘剂和食品的防腐剂等；是生产色淀颜料的沉淀剂，用于废纸加工脱墨等方面。

      液体氯化钙用途广泛，可用于污水处理，管道制冷剂（本产品呈弱碱性，可有效降低管道的腐蚀）。分子筛原料建筑凝结剂。实用简便、省工，可以降低工厂使用成本操作简单、方便，使用可靠，同时液体氯化钙市制冷工业中重要的冷冻机；也可用作海藻酸钢行业豆制品行业的絮凝剂等，是广大客户理想的化工产品。

Inorganic industrial used for manufacturing metal calcium, barium chloride, calcium salt (such as calcium phosphate) of raw materials. Construction industry is used as antifreeze, to speed up the concrete hardening and increase of building mortar. Microbial industry as culture medium for haploid breeding. Analysis is used for the determination of carbon steel in the learning, whole blood glucose solution, serum phosphorus and serum alkaline phosphatase activity, etc. Used for aluminum magnesium metallurgy protectant, refining agent. In addition, also used as fabric fire retardant, harbor of antifogging agent, road dust and food preservatives, etc. Is the production of lake pigment precipitation agent. Used in waste paper deinking processing.

Liquid calcium chloride are very versatile and can be used for sewage treatment, pipe refrigerant (this product is weak alkaline, can effectively reduce the corrosion of pipelines). Molecular sieve materials building condensation agent. Practical simple, save work, can reduce the cost for factory use the operation is simple, convenient, reliable operation. At the same time important refrigerator in the liquid calcium chloride in the refrigeration industry. Also used for steel industry alginate soy products, such as flocculant is the general customers the ideal chemical products.
