Decompression preservation is the preservation of fresh fruits, vegetables, flowers, meat, aquatic products and all perishable products by means of reducing atmospheric pressure. It is another new development of storage and preservation technology. Decompression and preservation storage is to put the articles in a closed and cooled container and pump them with a vacuum pump to make them have lower absolute pressure. The pressure should be determined according to the characteristics of the articles and the storage temperature. When the required low pressure is reached, fresh air is continuously passed through a pressure regulator, a humidifier and enters the storage room with an approximately saturated temperature. The vacuum pump is constantly working, and the items are constantly getting fresh, moist, low pressure, low oxygen air. Generally ventilated four times per hour, will be able to remove the field of heat, respiratory heat and metabolism of ethylene, carbon dioxide, acetaldehyde, ethanol and other unfavorable factors, so that the goods in the best long-term dormancy. This method solves the problems of weightlessness and wilting of stored goods, and not only preserves the moisture of the articles, but also reduces the consumption of nutrients such as vitamins, organic acids, and chlorophyll. Not only does the storage period extend three times longer than the average cold storage, the product preservation index is greatly improved, and the shelf life after delivery is also significantly increased. The characteristics of decompression and preservation technology mainly include: Rapid cooling of common constant temperature database and CA atmosphere control library have no rapid cooling function, need to be equipped with pre-cooling facilities, otherwise the vegetables and “hot fruit†in the storage will take dozens of hours or even days In order to achieve the appropriate low temperature. Because the decompression storage can create a low pressure environment and reduce the conditions for water vaporization, the entire warehouse can be cooled to a predetermined temperature in 20 minutes, which has laid a good foundation for preservation since the beginning. Rapid oxygen reduction, purification of general industrial decompression library at any time can reduce oxygen to 21% in 10 minutes, the accuracy of hypoxic control is 0.05%, as long as the pressure is constant, the concentration of low oxygen can be stable, which is ordinary Storage methods cannot be achieved. Since decompression and preservation can remove harmful gases at any time and maximize the physical health of the items, the stored foods are not aging, yellow, weightless, and not deteriorating, and the product rate is as high as 98%. Low energy consumption, multi-functional vacuum cooling, rapid cooling, good cooling effect, dual refrigeration and freezing dual functions. Efficient sterilization, elimination of residual industrial vacuum storage, the use of ozone for atmospheric and decompression sterilization, elimination of pollution residues, is considered to be the ideal measure today. Ozone is a broad-spectrum, high-efficiency bactericide. It is harmless to food and does not cause residual pollution. Using ozone under decompression can act on microorganisms that have submerged into the cortex and residual pesticides to achieve thorough disinfection. Simple, low cost, good results. The use of decompression and preservation technology can reduce food weight loss, rot, and aging to a minimum.
Disposable Gloves
Classification by use
Acid and alkali resistant gloves, electrical insulating gloves, radiation protection gloves, medical gloves and other rubber gloves.
According to the rubber raw material or manufacturing process, it is divided into Latex Gloves and molded gloves.
Acid and alkali resistant gloves should be able to be used in sulfuric acid (density 1.32) or caustic soda solution (density 1.19) at 45°C. Electrical insulating gloves are divided into two types: high voltage and low voltage. High voltage can be used below 6000 volts (test voltage is 12000 volts). Low voltage can be used below 1000 volts. Medical gloves are divided into two types: light surface and wool surface (hair surface gloves or wrinkled gloves).
Sort by material
According to the material, it is generally divided into plastic disposable gloves, latex disposable gloves, and nitrile disposable gloves;
Among them, plastic film gloves are generally used in non-professional occasions. The advantage is that they are cheap, but because plastic disposable gloves are not elastic, their durability and suitability are relatively poor;
Latex gloves are usually used in professional occasions, such as operating rooms, laboratories and other places that require high sanitary conditions. The advantage is that they have a certain degree of elasticity and are more durable, but they are not resistant to animal oil corrosion, and are easily corroded by contact with animal oil. More importantly, according to statistics, 2%-17% of people will have varying degrees of allergy to latex.
Nitrile Gloves, in addition to having the characteristics of latex gloves and improving the shortcomings of latex gloves, can first withstand the corrosion of animal oils and fats, and will not cause allergies.
