Under the condition of high temperature and humidity in summer, farmers who store phosphated insecticide grains should use it safely: grain storage containers should be sealed to prevent gas pollution and injury. It is forbidden to store phosphorus and aluminum indoors, and the fumigated grain storage room is connected to the living room. Pay attention to the ventilation of the room to avoid being inhaled by the human body; If symptoms such as dizziness, pain, chest tightness, nausea, etc. occur, they should be sent to the hospital in time.
Precautions for safe food storage
As farmers stored more wheat this year, the public used aluminum fumigation and fumigation. The high temperature and high humidity weather in summer is conducive to aluminum absorbing phosphorus gas released by water. Once used improperly, it is easy to cause severe harm to human body and even endanger life safety. Safety precautions for food storage are now proposed:
1. When fumigating and storing grain, close fumigation must be carried out strictly according to the instructions.
2. It is strictly prohibited to store phosphorus and aluminum indoors. Fumigation and storage in the living room are strictly prohibited. The room where fumigating grain is connected to the living room should pay attention to the ventilation of the room to prevent toxic gases from penetrating into the wall and being inhaled by the human body.
3. Phosphorus and aluminum should be kept away from children and should not be stored with food, drinks, feed and other items.
Fourth, in case of dizziness, pain, chest tightness, nausea, weakness, muscle tremors, dyspnea and other symptoms, they should be sent to the hospital in time.
Does the current gas concentration in the warehouse meet the entry conditions? When do you enter the warehouse now? Faced with these technical difficulties, Jun technology today wants to share with you the granary harmful gas detection system developed by Henan University of Technology. The detection system combines ZigBee wireless network technology, CAN field bus technology and modern sensing technology. The real experimental results show that the detection system runs stably, has strong anti-interference ability and reliable communication data, which is very suitable for the production and application of silos in our country. Working principle the granary is equipped with a data acquisition node with a gas sensor for collecting gas concentration data. Gas concentration data is transmitted through ZigBee wireless network and CAN bus network. After receiving the data, the data receiving node of the control terminal processes and analyzes the data, and sends the results to the upper computer for reference.
I. Functions of doors and windows
Doors and windows are the opening part of the building's external protective structure. They are extremely important functional components to resist wind and dust and realize the heat, sound and light environment of buildings, and have double decorative effects of building facade and indoor environment. It is directly related to the safe use, comfort and energy saving of buildings and the improvement of people's living standards.
Door leaf material and description
Thermal insulation material: polyurethane. Use high pressure injector to pour into the door blank in the mold cavity.
Panel material: stainless steel plate, plastic coated steel plate, rust-proof embossed aluminum plate, and aging-resistant FRP gel coat plate are adopted. The panel material designer can explain in the design description or directly to the manufacturer when ordering by the builder.
Door frame: the glass fiber reinforced plastic composite material is used to make a fully enclosed frame.
Sealing Strip: EPDM rubber products is adopted.
The unloading lock secape system in the freezer door, the stop or self-withdrawal device when the electric sliding freezer door is blocked, the opening and closing device at any position, the manual device when the electric freezer door is powered off, the electric heating device and various hardware accessories of the door can be equipped or selected.
Refrigerator door can be applied to assembly or cold storage, civil cold storage, constant temperature storage and constant temperature workshop with temperature not lower than-40℃. It can be divided into three types: electric refrigerator door, manual refrigerator door, and manual translation refrigerator door.
Main performance:
Refrigerator door the door leaf uses foam board or polyurethane as insulation layer, the panel material is color steel plate or stainless steel, and its heat transfer coefficient is 0.22W/m2? K (door thickness 150mm) makes the door have good heat insulation and sealing performance. The combination of door leaf, floor and door frame is customized in special form and sealed with special rubber strip. In order to prevent the combination of door leaf and door frame or floor from freezing, a low voltage and high efficiency electric heating device is added around the door.
The door is equipped with safety switch. If someone or a vehicle passes through the middle of the door when closing the door, the door may be opened by itself to avoid accidents.
When purchasing, in addition to the reputation of the manufacturer, attention should also be paid to the thermal insulation of the equipment and subsequent after-sales service.
Thermal insulation door just plays a role of heat preservation and sealing. We know that the pressure of grain is very high, and the food blocking board or food blocking door should be used in the door to block the grain and prevent the explosion of the warehouse. The production of grain blocking board is external galvanized board, filled with square tube skeleton and insulation board. Its choice must be thicker and stronger so as to block the pressure of grain. We bought Hengtai storage equipment with guaranteed quality.
