The demand of plastic bucket itself has certain transparency. Secondly, because of the demand of transportation or transfer process, it is required to have certain wear-resistant strength and impact resistance. In addition, in the acid and alkali profession, it is also required to have certain corrosion resistance. So the raw material selection of plastic bucket is very important. Because of the high light transmittance, plastic products must be strict in appearance quality, without any speckles, pores and whitening. Fog halo, black spots, discoloration, poor gloss and other shortcomings, so in the whole injection process on raw materials, equipment. Mold, and even product planning, should pay great attention to and put forward strict and even special requirements.
Plastic bucket has good heat and cold resistance, hardness, tensile strength, electrical insulation function and resistance, and has good chemical stability. It is almost insoluble in any organic solvent at room temperature, resistant to a variety of acid, alkali and salt solutions. It also has excellent resistance to environmental stress cracking and thermal stress cracking. It has high surface hardness and good scale stability.
The plastic bucket stacked on the tray shall be packed and fixed with winding film. During packing, the plastic bucket and plastic bucket shall not be squeezed and deformed mutually, with the deformation amount ≤ 5%; after packing, the number of stacking layers of the tray shall not be more than 2, and the upper base layer shall be aligned when stacking, so that the components of the upper layer are evenly applied to the base layer; the stacking place shall be flat on the ground and in a horizontal direction.
Plastic buckets are mostly used for dangerous goods packaging with good characteristics, which are not fragile, rusty, light, etc., and have excellent oil and corrosion resistance. It is mainly used for the packaging of dangerous goods requiring heat preservation, moisture-proof, pressure resistance and corrosion resistance. The material of plastic bucket is mainly made of polyethylene, polypropylene, polyester and other plastics, such as blow molding, injection molding, blistering and rolling.
