Application of Phosphine Transmitter in Granary
Regarding the use of highly toxic phosphine to eliminate insects in the granary, you must have seen articles like this in a certain C: 'Shock! A public official in the granary blatantly poisoned the grain but no one cares about it. The truth is unexpected. That's it!'. It is estimated that when everyone saw it, they thought it was another marketing essay and didn't care about it. So if the editor tells you: Food fumigation and insecticide have always been an indispensable part of the process of food storage and storage, and the protagonist of fumigation and insecticide is phosphine. How would you feel? Now let’s take a closer look at the real face of phosphine deworming, and by the way, let’s talk about the application of phosphine transmitter in deworming. Phosphine gas insecticide technology, because of its convenient use and high insecticidal efficiency, has been widely used as early as 30 years ago. Phosphine deworming is not simply spraying phosphine gas, but placing aluminum phosphide in a sealed warehouse; aluminum phosphide volatilizes into the air when the temperature is high, and absorbs moisture in the air. , A double hydrolysis reaction occurs to produce aluminum hydroxide Al(OH)3 and phosphine gas PH3 (highly toxic). Phosphine can eliminate all pests in the warehouse indiscriminately in a short period of time. Phosphine is effective for all animals as long as they have respiration, which of course includes insects and humans. The closed environment can ensure the efficacy of the medicine and also protect the personal safety of the farmers. After the deworming work is completed, the phosphine transmitter must be used to monitor the residual phosphine for safety. Laws and regulations on the exposure limit of phosphine my country stipulates that the maximum allowable exposure limit of phosphine in the granary is 0.3 mg/m3, which is 0.22 ppm; the American Conference of Governmental Industrial Hygienists (ACGIH) stipulates The maximum allowable exposure limit for phosphine in a normal 8-hour working day is 0.42 mg/m3. That is 0.31ppm, and the agency also stipulates that when the phosphine content in the warehouse air reaches 1.4mg/m3. The maximum allowable contact time for workers is 10 minutes. According to the above laws and regulations, the phosphine transmitter should monitor the phosphine concentration in the warehouse in real time to make the concentration lower than the 0.22pmm prescribed by our country to ensure the safety of workers. The range of the phosphine transmitter is 0-20ppm, the range is wide, and the measurement accuracy is high. It can reach within ±3% F·S, and the repetition rate can reach within 2%. Effectively ensure the life, health and safety of staff. Phosphine transmitterThe phosphine transmitter adopts the imported first-line brand electrochemical phosphine sensor, which has the characteristics of rapid response, strong anti-interference ability, and has a unique Compensation algorithm, multi-stage standard gas calibration, also has the characteristics of long life, high precision, high repeatability and high stability. In addition to being used for phosphine deworming in granaries, it is also suitable for underground parking lots, garages, workshops, enclosed living places and other occasions where the concentration of phosphine needs to be detected. The phosphine transmitter adopts wide voltage 10-30V DC power supply, 485 signal output, standard Mod bus-RTU communication protocol, Mod Bus address can be set, the baud rate can be changed, and the communication distance is up to 2000 meters. The outer shell is made of king-shaped shell with high anti-skid grade, which can reach IP65, which can adapt to the harsh environment of the site. In addition to monitoring phosphine, the high phosphine transmitter can be equipped with a temperature and humidity sensor to monitor temperature and humidity, or a high-quality OLED display can be selected, and the value can be directly viewed on site, even at night Clearly displayed. Phosphine is widely used in pest control and killing in grain depots. Due to the highly toxic properties of phosphine, natural ventilation or mechanical ventilation should be used to diffuse the air for 3-5 days after the fumigation and anti-virus is completed. However, it is inevitable that there will be blind spots in ventilation, and news of deaths caused by inhalation of phosphine by granary staff have also occurred from time to time. The editor here advises all the staff to do a good job of inspection after killing the insects to prevent other occurrences.
