Bubbles sometimes appear in the production of plastic barrels. What will the production personnel do? Let the plastic bucket wholesale to answer for you. After the plastic bucket is filled with liquid, screw the vent cap, lie on the side for 1 minute, make the permeable film soak the liquid, and then store the plastic bucket vertically for 3-7 days or longer. The specific test time needs to be determined by oneself, and the temperature should follow the temperature under the practical application state (the bucket is placed in the oven after the liquid is filled). The storage temperature of the plastic bucket is generally 40-50 ℃. When the expected time is up, check whether the bucket expands. If there is slight swelling, the demander will decide whether to use it; If there is serious bulge, it is determined that this ventilation cover is not applicable.

Blow molding is also one of the processing methods for making plastic barrels. More than 1/3 of HDPE in the United States is used for blow molding. The characteristics of blow molding grades, such as melt strength, ES-CR and toughness, are similar to those used for sheet and thermoforming applications, so similar grades are acceptable. Most thermoplastics can be blow molded, and high-density polyethylene is a blow molding material that is widely used. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. Now there are also multi-layer blow molding and stretch blow molding. It is very reliable and convenient to use the above methods to process plastic barrels, and the manufacturer is constantly developing new processing methods. I believe that in the future, the processing of plastic barrels will be more and more perfect, and the quality of plastic barrels will be more reliable.

The volume of the plastic bucket oil tank is too small, the heat dissipation area is not enough, and the cooling device has too small capacity. The high temperature of climate and operating environment causes the oil temperature to rise. The viscosity of the selected oil is not appropriate, the viscosity is large, the viscosity resistance is large, and the leakage will increase if the viscosity is too small, both of which can cause heating temperature rise. The pipeline of the plastic bucket system is too thin and too long, too much bending, and large local pressure loss and pressure loss along the way. The precision of components is not enough and the assembly quality is poor, and the mechanical friction loss between relative motions is large. The fit clearance of the mating parts is too small, or the clearance is too large after use, resulting in large internal and external leakage, resulting in large volume loss. For example, the volume efficiency of the pump is reduced, and the temperature rises quickly. The constant displacement pump oil supply system of the plastic bucket with the oil pump capacity selected according to the fast forward speed will have most of the excess flow overflowing from the overflow valve under high pressure and generate heat during operation. The unloading circuit in the system fails or the oil pump cannot unload when it stops working because no unloading circuit is set. All flow of the pump overflows under high pressure, causing overflow loss and heating, resulting in temperature rise.

With the use rate of 200L large plastic barrels getting higher and higher, more and more old plastic barrels begin to appear gradually, including some plastic barrels that are broken during transportation, so we specially talk about how to repair the cracks on the plastic barrels. Now 200L plastic drums basically contract the transportation of chemical products, and the cost of plastic ton drums is also very high. If the old and damaged ton drums are replaced with new ones, the cost is too high. So let's talk about the repair of plastic buckets. Plastic buckets are indeed carriers for transporting chemical products, even dangerous plastic buckets, but they are not irreparable. The glue specially used to repair the plastic bucket is AB glue, which is composed of two kinds of glue liquids, one is hardener and the other is the glue. The combination of two liquids can achieve good bonding effect of zui, and the temperature must be appropriate. Although the use conditions are harsh, the bonding effect of the plastic bucket is extremely good. The 200L plastic bucket we usually use is always transported on the truck, and damage is inevitable during long-distance transportation. So many enterprises using plastic ton buckets will prepare sufficient AB glue.

For chemical drums, it is very important to master the temperature. Because temperature has a significant impact on the function of plastic extrusion and parison, improving the extruder temperature can reduce the viscosity of the melt, improve the fluidity of the melt, and improve the screw speed without affecting the mixing and plasticization of plastic. To achieve this goal, we can use electronic temperature controller to make the process temperature stable and save energy significantly. It must be well understood that humidity will affect the drying rate of chemical drums. When the relative humidity in the bucket is low, the pressure difference between the surface and the water vapor in the dryer is large, and the drying speed is fast. The isolation function of chemical drums from oxygen, carbon dioxide, nitrogen and organic solvents can vary by tens or even hundreds of times, and the basic characteristics of plastic containers should be grasped. Therefore, when selecting plastic containers, it is necessary to fully understand that plastic related functional chemical barrels are generally made by molding. Different molding methods often have a great impact on the function and cost of products.
