Protective Equipment

  I believe that most people are as used to pushing trolleys when going to the supermarket, just like the editor. Parents with babies prefer to put the baby on the stroller so that they can buy and buy at the supermarket with confidence. But, do you know how many viruses and bacteria the shopping cart carries? If you are not careful, you may get seriously ill! Last year, a real case occurred in Australia! The baby's mother took him to the supermarket to buy things, and then the mother put the baby on the stroller as usual. The mother and daughter had a good meal in the supermarket and went home after the tragedy. This happens about 24 hours after shopping. The baby named Logan started vomiting and diarrhea and had a high fever. Due to severe diarrhea, he was sent to the hospital with blood in his stool. The baby's heartbeat has reached 200-220 beats per minute! The medical staff performed an ultrasound, nasal secretions, and urine tests for him. Finally, the doctor confirmed th...

  Nitrogen is the main component of air. Nitrogen accounts for about 79% of air and oxygen account for 20.9%. Nitrogen is a colorless, odorless, non-toxic, and non-flammable gas at room temperature and atmospheric pressure. It has a boiling point of -195.8°C. It has very stable chemical properties and hardly reacts with other substances. In addition to synthetic ammonia,   nitrogen is usually used as a protective gas in metallurgy, chemical, coal, food, medicine, electronics, magnetic materials, transportation, heat treatment, tires, thermoelectricity, aviation, and other industries. PSA pressure swing adsorption nitrogen generator, using air as raw material, carbon molecular sieve as adsorbent, using pressure swing adsorption principle, using carbon molecular sieve to selectively adsorb oxygen and nitrogen to separate nitrogen and oxygen, commonly known as  PSA nitrogen production . This method is a new nitrogen production technology that developed rapidly in the 1970s. ...

  PSA (pressure swing adsorption) nitrogen generator  operation and matters needing attention: 1. Installation requirements 1.1 A large enough site should be selected according to the actual size of the equipment. It is best to keep the distance from the surrounding environment at least 1 meter to facilitate operation and maintenance. 1.2 The installation site must have good ventilation and little dust. 1.3 It cannot be installed in a corrosive environment. 1.4 The muffler (exhaust gas outlet of the  PSA nitrogen generator ) can be installed indoors or outdoors. When the air compressor and the nitrogen generator are in the same room, the muffler should be installed outdoors to avoid affecting nitrogen production. 1.5 The nitrogen generator should be placed in a poorly ventilated place, and the muffler should be installed outdoors. 1.6 If the muffler is installed outdoors, the muffler installed outdoors should have rain-proof facilities and pay attention to its placement h...
