Let me share with you the advantages of using plastic buckets! In terms of convenient use of plastic buckets, the first is the plastic buckets with small capacity and light packaging weight. The main body of this kind of plastic bucket packaging is the function scheme of the handle. It is an important part of the demand thinking of the plastic bucket scheme to make the handle more labor-saving and convenient to use. There is a need for more thoughtful ideas about large capacity plastic buckets. For example, some large plastic waste barrels loaded with wheels are very convenient to push, pull and use. The second is the use of plastic buckets. Plastic barrels are usually quoted at a higher price, and also have been used. For example, many migrant workers use paint plastic buckets to hold clothes, rice and pickles. From the perspective of convenient use, we think that it is necessary to think about convenient cleaning and disinfection of plastic buckets. After all, the recycling rate of plastic drums is also a demand driven direction. Nowadays, recycling of plastic drums is very low. The recycling of plastic bottles involves recovery, equipment and other aspects, and the demand is promoted step by step.

Plastic barrels are the most widely used container products nowadays. Generally, plastic barrel manufacturers have a variety of processing methods. Plastic barrels are made of PE, mainly ethylene, and some propylene and hexene are used as copolymers. Then, under the action of catalyst, some polymerization processes are used to produce plastic buckets. The production methods of plastic buckets include extrusion, blow molding, injection molding, rotational molding, etc. Blow molding, extrusion molding and injection molding are commonly used. Now let's get to know. First choice, extrusion mode: extrusion mode is also called extrusion blow molding, which is a plastic molding process. Extrusion is to heat the plastic raw materials to make them appear viscous flow, then pressurize them, and then cool them through the extrusion mold. Extrusion is a method of manufacturing hollow thermoplastic parts, which is generally used for bottles, barrels, cans, boxes and other containers. The common extrusion material is high-density polyethylene. The process of extrusion process is: solid plastic plasticization, molding, and shaping. According to the physical state, the extrusion method can also be divided into dry extrusion and wet extrusion. In addition, the compression method for plastic is also different, including continuous extrusion and gap extrusion. The extrusion mode has the following advantages: continuous, high productivity, low investment, low cost, simple operation, easy process control, and uniform quality.

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.

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.
