Although plastic buckets can be seen everywhere, do you know how they are packaged? What technology is there for packaging? 1. Plastic packaging barrel packaging: Fieldbus technology. The use of fieldbus technology has mainly "liberated" most of the hardware, simplifying the cumbersome device links; In the practical process of production and use, convenience and flexibility become more and more obvious; It can integrate fieldbus skills with the ERP system, so that the management can easily access and analyze operating data through the ERP system, understand the production practice and immediate situation, and monitor the operation of the workshop. Fieldbus technology is widely used in large food processing enterprises in China, which facilitates the unmanned operation of the entire production line and the seamless connection of transmission, detection and other processes. 2. Sensor plastic packaging barrel packaging technology. In the food processing and packaging machinery profession, the use of sensors is complex, and sensors are used in the monitoring of food and beverage storage tanks, filling and packaging, mixing and processing, cooling and heating, cleaning, packaging and other processes. The gap in the market for the use of this skill has become a must for many automation manufacturers. 3. Drive operated packaging barrel packaging technology. The use of transmission products in packaging machinery is mainly to adjust the main process speed and control the periodic change of motor speed in the production process. But for most packaging machinery, frequency converter is not a necessary electrical product. The application rate of frequency converter in this profession is low, and there is a large space for development in large standard machines and packaging production lines.

Main properties and characteristics of plastic barrels ① A few plastic packaging barrels have poor high temperature resistance and become brittle under high temperature; ② Good resistance to attack and attack, will not produce serious repercussions; ③ It has good general formability and colourability, and low processing cost; ④ Good insulation and low thermal conductivity; ⑤ Good transparency and wear resistance; ⑥ Most plastic packaging barrels have poor heat resistance, high shrinkage rate and are easy to extinguish; ⑦ Poor dimensional invariance and easy deformation; ⑧ Most of the plastic packaging barrels are light in weight, chemical properties remain unchanged, and will not breed serious reverberation and rust during operation; ⑨ Plastic packaging barrels are prone to aging, which will affect the operation efficiency and price in the long run; ⑩ Some plastic packaging barrels are easily soluble in solvents, and will melt when touching certain solvents.

In addition, when the plastic bucket is exposed to light, there will be temperature changes, which can be regarded as heating. The increase of temperature will accelerate the dispersion of oxygen, and then increase its oxidation rate, which will lead to thermal bonding and cracking. In addition, touching the oxygen in the air and even ozone, over fire bonding or molecular chain cracking can accelerate aging, and there are other elements such as water, high-energy radiation The media, etc. Therefore, try not to expose to the sun when using plastic buckets daily. These are the reasons why plastic drums are easy to age summarized by the manufacturer of plastic drums. Plastic buckets can be seen almost everywhere in life. Although their price is not expensive, people should also pay attention when using them. Plastic is a kind of aging material, especially under ultraviolet radiation, its aging speed will be greatly accelerated. Therefore, plastic buckets need to be carefully stored to avoid long-term storage under high temperature, direct sunlight and other environments.

The plastic bucket for holding water is made of PE raw material, and its composition is attributed to linear low-density polyethylene particles. The plastic bucket made of this raw material is very healthy and environmentally friendly, and meets the national food safety standards. It not only has rigidity and resistance, but also has advantages such as high temperature and cold resistance. Generally speaking, plastic buckets have two purposes, one is to hold water, the other is to hold some corrosive liquids, so their choice of raw materials is different. Plastic buckets used to hold water should be environmentally friendly, green and healthy; The drums for storing corrosive liquids are required to be resistant to acid and alkali and corrosion. Plastic bucket is widely used in civil, agriculture and industry, and its scale of use can be classified as follows: 1. Civil: it is used to store and supplement at night (urban water consumption is low) because of drinking water supply problems, and it is used to make up for the overall water supply system when water consumption is serious; 2. Agriculture: when the rain is scarce, it is used to make up for the water content of farmland crops and drinking water for farm animals; 3. Industry: It is used to store industrial raw materials, and has ambitions for various acidic and alkaline industrial raw materials. Plastic buckets are ubiquitous in our lives. Because of their strong adaptability to the environment and high tear resistance, plastic buckets are loved by modern people, widely used in some factories, enterprises and individual families, and have been recognized and praised all the time.

Why is the chemical barrel deformed? 1. In actual use, the chemical barrel will be deformed due to the great difference in the thickness of the barrel wall. However, the machines used to make chemical barrels in China are relatively backward, and there are fewer control points for wall thickness, which results in the asymmetry of the barrel body. Therefore, when formulating the standards for chemical barrels, they are also relatively loose. In some cases, the two relatively symmetrical wall thicknesses are about 2:1. The chemical barrel with uneven wall thickness is often judged as qualified when dissecting. 2. According to relevant people, the ambient temperature is the main factor causing the deformation of plastic chemical barrel. We should control the ambient temperature of plastic chemical barrel to prevent it from deformation. The plastic chemical barrel can carry a high heat of 108 degrees, and a low heat of 70 degrees below zero. Therefore, in general, the temperature of the liquid carried by the plastic chemical barrel should be 40 degrees below zero to 60 degrees below zero. If this value range is exceeded, when the chemical plastic bucket device weighs more or the temperature is higher, protective measures should be taken for the plastic chemical bucket to avoid deformation of the plastic chemical bucket. 3. After the chemical drum is filled with liquid goods, after the lid is tightly rotated, because it is airtight, when the liquid inside is cooled, the pressure inside the drum becomes smaller, while the external pressure is larger, forming the pressure difference between the surface and the inside of the drum, causing the deformation of the chemical drum. The inspection procedure for chemical drums clearly stipulates that they should be sealed and airtight. If the liquid inside is dangerous goods, the chemical drums for Class I dangerous goods should be able to accept a pressure of 30Kpa/cm2, and the plastic drums for Class II and III dangerous goods should also be able to accept a pressure of 20Kpa/cm2.
