1, color selection
Requires bright colors and no color difference. It is best to choose a transparent color, followed by a single bright color. Do not choose black, because black is easy to add secondary materials, recycled materials, but it is difficult to distinguish.
2, appearance selection
Touch the edges with your hands, there is no significant cloak, chamfering at each corner, not scratching your hands. The rubber surface is free from impurities and black spots. The appearance of the bucket is transparent and smooth, and the finish is good. In order to avoid inspection, many plastic buckets are coated with a thin layer of good material on the surface. The typical gold jade is ruined. It is necessary to pay attention to see if there is any possibility of water leakage.
Feel softIt is suitable for slippery and comfortable, and the sound of the barrel wall is crisp with your fingers. There is no rough feeling on the wall surface, and the rubber surface is flat and there is no shortage of glue.
In general engineering plastics, living plastics have no pungent odor, such as PP, PE, PC, PS, etc. If there is an unpleasant smell in the lid bucket and it is very irritating, then don't buy it. It is most likely made of secondary material and recycled material.
5, institutional performance
The plastic barrel produced by pure raw materials has good toughness and impact resistance, and rebounds quickly after artificial pressure deformation. The weather resistance is generally between -40 ° C and 80 ° C, and the melting point is generally higher than 260 ° C.
