磷酸，是一種常見的無機(jī)酸，化學(xué)式為H3PO4。不易揮發(fā)，不易分解，在空氣中容易潮解。磷酸屬于中強(qiáng)酸，其結(jié)晶點(diǎn)為21℃，當(dāng)?shù)陀诖藴囟葧r(shí)會(huì)析出半水物結(jié)晶。加熱會(huì)失水得到焦磷酸，再進(jìn)一步失水得到偏磷酸。磷酸具有酸的通性，其酸性比鹽酸、硫酸、硝酸弱，但比醋酸、硼酸等強(qiáng)。下面
順酐廠家為您講解下該產(chǎn)品的相關(guān)內(nèi)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
醫(yī)學(xué)：磷酸可用于制取含磷藥物，例如甘油磷酸鈉等。農(nóng)業(yè)：磷酸是重要的磷肥（過磷酸鈣、磷酸二氫鉀等）的原料，也是飼料營(yíng)養(yǎng)劑（磷酸二氫鈣）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：磷酸是食品添加劑之一，在食品中作為酸味劑、酵母營(yíng)養(yǎng)劑，可口可樂中就含有磷酸。磷酸鹽也是重要的食品添加劑，可作為營(yíng)養(yǎng)增強(qiáng)劑；
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;
工業(yè)：磷酸是一種重要的化工原料，主要作用如下；
Industry: Phosphoric acid is an important chemical raw material, with the main functions as follows;
1.處理金屬表面，在金屬表面生成難溶的磷酸鹽薄膜，以保護(hù)金屬免受腐蝕；
1. Treat the metal surface and generate insoluble phosphate films on the metal surface to protect the metal from corrosion;
2.和硝酸混合作為化學(xué)拋光劑，用以提高金屬表面的光潔度；
2. Mix with nitric acid as a chemical polishing agent to improve the smoothness of metal surfaces;
3.洗滌用品、殺蟲劑的原料磷酸酯；
3. Phosphate esters as raw materials for the production of washing products and insecticides;
4.含磷阻燃劑的原料；
4. Raw materials for producing phosphorus containing flame retardants;
與多家國(guó)企企業(yè)建立長(zhǎng)久的合作關(guān)系
Establishing long-term cooperative relationships with multiple state-owned enterprises
使用磷酸時(shí)注意事項(xiàng)
Precautions when using phosphoric acid
為了保護(hù)皮膚免受磷酸影響，我們建議穿著化學(xué)防護(hù)服，例如靴子、防護(hù)服和手套,我們還建議您購(gòu)買天然橡膠、聚氯乙烯、丁腈橡膠、丁基橡膠或氯丁橡膠制成的皮膚防護(hù)裝備。
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.
為了保護(hù)面部或眼睛免受刺激性和腐蝕性物質(zhì)的影響，我們建議使用護(hù)目鏡進(jìn)行化學(xué)防護(hù)。
In order to protect the face or eyes from irritating and Corrosive substance, we recommend using safety goggles for chemical protection.
除了一般的排氣通風(fēng)外，我們還建議使用局部排氣通風(fēng)來防止使用磷酸時(shí)的呼吸風(fēng)險(xiǎn),采取一切必要的環(huán)境預(yù)防措施，并且可能需要直接在室外排放煙霧。更多相關(guān)事項(xiàng)就來我們網(wǎng)站
