Phosphoric acid is an important raw material for agriculture, industry, and feed nutrients. It has applications in food and medicine. It can be said that it can be seen everywhere in life. Phosphoric acid is a common inorganic acid and a medium-strong acid. Its acidity is weaker than strong acids such as sulfuric acid, hydrochloric acid, and nitric acid, but weak acids such as acetic acid, boric acid, and carbonic acid are stronger. Phosphoric acid is a corrosive substance and has a strong corrosive effect on the skin. It can cause skin inflammatory diseases and cause systemic poisoning. Phosphoric acid vapor can directly cause the nasal mucosa to shrink. The maximum allowable concentration in the air is 1mg/1m³. Production personnel should wear appropriate protective equipment such as work clothes, rubber gloves, rubber or plastic aprons, and long rubber shoes in strict accordance with the requirements. Respiratory organs, eyes, wear masks, and other protective items as required and prevent phosphoric acid from splashing on the skin. A small amount of it can be rinsed with water and related ointments. In severe cases or large-scale splashes of the whole body, they should be sent to the hospital for treatment immediately.
The corrosiveness of 85% phosphoric acid can increase with the increase in temperature. Generally, the temperature is below 80°C. In this case, 321 stainless steel can be used as a storage tank at room temperature, and 316L stainless steel is used for the production process. , Phosphoric acid filling equipment used at room temperature is made of 316L stainless steel, which has good corrosion resistance and can meet the requirements in terms of cost and performance.
The use of semi-automatic filling machines and fully automatic filling machines in phosphoric acid processing plants can improve filling efficiency and avoid direct contact with the human body as much as possible to reduce personal injury to operators. Large-scale processing plants have high output and use automatic filling machines; small-scale processing plants have low output and can choose single-head semi-automatic filling machines or double-head semi-automatic filling machines according to specific needs.
Automatic gun weighing filling, accurate and stable filling, simple operation, full Chinese operation interface, free adjustment of filling specifications, whether it is 5.525kg, 10kg, 20.456kg, and the graduation value is only 1g, which improves the filling speed At the same time, it also standardizes filling specifications and is easy to operate by personnel. It is the first-choice filling equipment for many small and medium-sized enterprises and even large-scale production enterprises.
If single-head filling cannot meet the demand for filling volume, double-head filling machines or even multi-head filling and automatic filling equipment can be used. With the current rising personnel costs and various production costs that cannot be bear, it should be from the aspect of automation equipment. Start with, really achieve small investment and big return. Due to the strict selection of raw materials and production materials, the equipment has a low failure rate and is durable. A single investment can be used for three years or even five years or more.
