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

When wholesaling plastic buckets, you must pay attention to the choice of plastic materials! The wholesale orientation of plastic drums can only be carried out in the viscous flow state. Both chain segment orientation and whole chain orientation are thermodynamic non-equilibrium states. When the external force is released, the chain will be in a random state again due to the thermal movement of molecules, which is called solution retrieval. Only when the chain segment or molecular chain after removal is rapidly cooled to the glass transition temperature can the removal space be retained. This "frozen" orientation is only relatively stable, and it will also be slowly de oriented. As the material temperature increases, the recovery will rapidly advance ˉ The orientation of molecular chains will be produced in the melting process of plastics, such as injection and extrusion. The effect of orientation on the product is the anisotropy of properties. The strength and modulus in the orientation direction increase significantly, and the strength and modulus perpendicular to the orientation direction decrease significantly. This is because the atoms of the molecular chain in the orientation direction are bound by chemical bonds, while the force between the molecular chains perpendicular to the orientation direction is the van der Waals force.

For the newly bought plastic bucket, put two pieces of fresh lemon into the cup, put the quilt in the bucket, and then cover it for a few hours; Wipe the inner wall of the plastic bucket with soaked tea, and wash it with clean water to remove the peculiar smell in the bucket; In addition, use a few milliliters of salt dipped in water to scrub inside the bucket to remove odor. Through the above tips, you can effectively remove the odor of newly bought plastic barrels. As an enterprise specializing in the production of various plastic barrels, we are very cautious in the selection of raw materials, in order to reduce the impact of the odor of plastic barrels on purchasing judgment. If there is anything that consumers do not understand about the removal of odor from plastic barrels, they can contact us, and we are happy to serve you.
