磷酸，是一种常见的无机酸，化学式为H3PO4。不易挥发，不易分解，在空气中容易潮解。磷酸属于中强酸，其结晶点为21℃，当低于此温度时会析出半水物结晶。加热会失水得到焦磷酸，再进一步失水得到偏磷酸。磷酸具有酸的通性，其酸性比盐酸、硫酸、硝酸弱，但比醋酸、硼酸等强。下面
顺酐厂家为您讲解下该产品的相关内容：
Phosphoric acid is a common Mineral acid with the chemical formula H3PO4. Not easily volatile, not easily decomposed, and easily deliquescent in the air. Phosphoric acid belongs to the category of moderately strong acids, with a crystallization point of 21 ℃. When it falls below this temperature, semi aqueous crystals will precipitate. Heating will lose water to get Pyrophosphoric acid, and then further lose water to get metaphosphoric acid. Phosphoric acid has acidic properties, with weaker acidity than hydrochloric acid, sulfuric acid, nitric acid, but stronger than acetic acid, boric acid, etc. Below, the maleic anhydride manufacturer will explain the relevant content of this product to you:
磷酸—用途
Phosphoric acid - usage
医学：磷酸可用于制取含磷药物，例如甘油磷酸钠等。农业：磷酸是重要的磷肥（过磷酸钙、磷酸二氢钾等）的原料，也是饲料营养剂（磷酸二氢钙）的原料；
Medicine: phosphoric acid can be used to produce phosphorus containing drugs, such as sodium Glycerol 3-phosphate. Agriculture: phosphoric acid is an important raw material for the production of phosphate fertilizer (Superphosphate, Monopotassium phosphate, etc.), as well as for the production of feed nutrient (Monocalcium phosphate);
食品：磷酸是食品添加剂之一，在食品中作为酸味剂、酵母营养剂，可口可乐中就含有磷酸。磷酸盐也是重要的食品添加剂，可作为营养增强剂；
Food: Phosphoric acid is one of the food additives, used as a souring agent and yeast nutrient in food. Coca Cola contains phosphoric acid. Phosphates are also important food additives and can be used as nutritional enhancers;
工业：磷酸是一种重要的化工原料，主要作用如下；
Industry: Phosphoric acid is an important chemical raw material, with the main functions as follows;
1.处理金属表面，在金属表面生成难溶的磷酸盐薄膜，以保护金属免受腐蚀；
1. Treat the metal surface and generate insoluble phosphate films on the metal surface to protect the metal from corrosion;
2.和硝酸混合作为化学抛光剂，用以提高金属表面的光洁度；
2. Mix with nitric acid as a chemical polishing agent to improve the smoothness of metal surfaces;
3.洗涤用品、杀虫剂的原料磷酸酯；
3. Phosphate esters as raw materials for the production of washing products and insecticides;
4.含磷阻燃剂的原料；
4. Raw materials for producing phosphorus containing flame retardants;

使用磷酸时注意事项
Precautions when using phosphoric acid
为了保护皮肤免受磷酸影响，我们建议穿着化学防护服，例如靴子、防护服和手套,我们还建议您购买天然橡胶、聚氯乙烯、丁腈橡胶、丁基橡胶或氯丁橡胶制成的皮肤防护装备。
To protect your skin from phosphoric acid, we recommend wearing chemical protective clothing, such as boots, protective clothing and gloves. We also recommend that you buy skin protective equipment made of natural rubber, PVC, Nitrile rubber, Butyl rubber or Neoprene.
为了保护面部或眼睛免受刺激性和腐蚀性物质的影响，我们建议使用护目镜进行化学防护。
In order to protect the face or eyes from irritating and Corrosive substance, we recommend using safety goggles for chemical protection.
除了一般的排气通风外，我们还建议使用局部排气通风来防止使用磷酸时的呼吸风险,采取一切必要的环境预防措施，并且可能需要直接在室外排放烟雾。更多相关事项就来我们网站
