The wholesale of plastic drums with polar groups will make the materials hygroscopic. If stabilizers, plasticizers, fillers and other additives in plastics contain hydrophilic groups, polar groups, etc., they will also increase the rate of moisture absorption of materials. The rate of moisture absorption of plastics from the air is also related to the specific surface of materials. The feeding state of plastic materials is mostly granular (thermoplastic) (thermosetting plastic molding powder, some thermoplastic resin powder), with large specific surface area and fast moisture absorption rate from the air. Long term stored plastic is easy to achieve moisture absorption balance and contains more water. Before molding, it must be fully dried, otherwise there will be surface silver filaments, internal bubbles and other defects during the molding of products, and some plastics will be hydrolyzed and degraded, which will cause the hygroscopicity of plastic products under mechanical properties to affect the performance of products, Inhalation of moisture inside the products often acts as a plasticizer, which significantly reduces the wholesale of plastic barrels, changes the mechanical properties, and the plastic with obvious moisture absorption also has an impact on the size of plastic parts.

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.

First, the outer cover needs to be tightened when installing (usually with the help of external force such as wrench). After the installation of the seal ring, it should be close to the contact plane of the barrel mouth to prevent the seal ring from distorting the installation. If the temperature of the filled product is higher than 40 ℃, the cap shall be screwed and stacked after the product is cooled. When stacking, pay attention to ensure the flatness. The upper base layer with large contact area shall be aligned, and the stacking shall not be staggered to avoid deformation of the plastic bucket. The weight or specific gravity of the dangerous goods contained in the chemical barrel shall not exceed the larger weight or specific gravity of the contents that can be carried. It is not allowed to use plastic drums with low hazard class to pack dangerous goods in places where high hazard class packaging is required. If the plastic drum without vent hole is used for shipment, it will release gas during storage and transportation. The single weight or volume of dangerous goods contained in the barrel shall not exceed the high limit of the world rules for dangerous goods transportation. During loading, unloading and transportation, it is necessary to avoid falling and collision with hard and sharp objects. When loading dangerous goods, do not corrode or damage the appearance of the plastic barrel.

The orientation will also cause the difference of shrinkage and refractive index between the two directions of the product. In the production process of injection products, orientation is often used to improve the mechanical properties of the product in a certain direction. The orientation will also have an adverse effect on the product, making the product change its size, produce deformation or even crack in the direction perpendicular to the orientation due to the process of de orientation in the working process). In view of this situation, necessary treatment such as heat treatment should be carried out in advance after the molding of the work in progress, to create the necessary conditions for the reorientation of the oriented molecules, and to avoid the "freezing" of the molecular chain orientation in the work in progress, which brings about the above drawbacks during the injection, extrusion and other molding processes, the material molecular chain only produces uniaxial orientation. Uniaxial orientation has been fully applied in the production of plastic single fiber and film, which is used to improve the strength of single dimensional length direction and the strength of film in a certain direction. Biaxial orientation can improve the strength in all directions of the film plane, and also can improve the strength of the plexiglass plate. 5) Hygroscopicity Hygroscopicity refers to the tendency of plastic materials to absorb water from the air. Some plastics, such as polyamide and phenolic plastics, have an obvious moisture absorption tendency due to the hydrophilic group of resin molecular chain 1.

Briefly describe the characteristics of the packaging barrel: 1. When moving, you can also choose the method of horizontal rolling and lateral rotation. 2. It has good anti-corrosion function and is suitable for packaging of various chemical risk products. 3. The residue after dumping is small and simple to clean, which is suitable for repeated use of screens. 4. It has a long service life and can be used for more than 20 times under the normal side of flooding, transportation and loading and unloading. 5. The size meets the requirements of world container transportation, and the 20 foot container can load 80. 6. It can be used for hot filling. One Wengding Warehouse should not catch up with OAC. After hot filling, the lid and stacking shall not be closed until the contents have cooled sufficiently and dropped to room temperature. 7. If it is used to contain easily differentiated chemicals, Danduo should be equipped with Yizi with qi expelling function to prevent the risk of overpressure in Tannuo coating, and the red fork can keep the sealing function of Hanshi night body in mind.
