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 they 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.

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 method to deal with bubbles in plastic bucket production is to increase injection energy, pressure, speed, time and material amount, and increase back pressure to make the mold full. Increase material temperature and flow smoothly. Reduce the material temperature and shrinkage, and advance the mold temperature properly, especially the part of mold temperature that constitutes the vacuum bubble. The gate is set at the thick part of the workpiece to improve the activity of the nozzle, runner and gate and reduce the consumption of pressing. Improve the mold exhaust condition. The uneven movement of plastic in the mold makes the air trapped in it. When the plastic enters the warm air workshop, the moisture will condense on the cold plastic. The recommended remedy is to dry the plastic. Store the polymer in the workshop for at least six hours before injection molding. The plastic bucket is used to store all kinds of liquids. When we install the liquid and screw the vent cover, we need to lie on the side for one minute first, so that the vent film can be stored vertically after soaking the liquid. The storage temperature of the plastic bucket should also be noted, which is generally about 40~50 ℃. After a certain period of storage, check whether there is expansion. If the bulge is serious, it means that the ventilation cap is not applicable

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.
