There are several ways to remove the residue on the plastic packaging bucket: because the plastic packaging bucket is made of PE, after using the plastic bucket, there will be a lot of oil stains on the inner wall of the bucket, and it is also very difficult and troublesome to clean. Now, Shandong Zhongcheng Packaging Co., Ltd. will introduce the method to remove the residue of plastic chemical barrels. When we remove the residue on the chemical barrel, whether using polishing water or vinegar, we should ensure that it is soaked for a long time, so as to ensure that the residue in the barrel can be removed. Find a piece of dry cloth dipped with vinegar to cover it on the chemical plastic bucket with residue. After the impurities on the bucket are soaked, use a hard small slice to easily remove the residue of trade.

Chemical plastic bucket has good heat resistance and cold resistance, good hardness, tensile strength, electrical insulation performance and toughness, and good chemical stability. It is almost insoluble in any organic solvent at room temperature, resistant to corrosion of various acid, alkali and salt solutions, and has excellent resistance to environmental stress cracking and thermal stress cracking. Its surface hardness is high, Good dimensional stability. Chemical plastic bucket is easy to use, economical and durable. With the development of internationalization, plastic bucket has gradually become the mainstream product of liquid packaging. It can contain Class II and III dangerous goods. The liquid density for Class II dangerous goods is 1.5g/cm3, and the liquid density for Class III dangerous goods is 1.8g/cm3. The product structure is reasonable, firm and solid, which can be directly loaded and unloaded by forklift, and can be stacked and stored. The plastic container is light and not fragile. Chemical plastic buckets, plastic pots and bottles for daily food storage are mostly made of polyethylene or polypropylene, of which polyethylene is more common. PVC can also be made into containers such as barrels and basins, but like film, it cannot hold food, especially oil and wine. There are also pulse formaldehyde plastics commonly known as "Dianyu" and melamine formaldehyde plastics commonly known as "melamine". The raw materials contain formaldehyde. In the production process, if the polymerization is not good, free formaldehyde may appear in tableware. Formaldehyde is a highly toxic substance. If it is mixed with food, it will seriously damage human health. Therefore, good quality "electric jade" and "melamine" tableware and containers must be used. For inferior products, the relevant departments should strictly check to prevent them from coming out of the cage. Although polyethylene container can be used to hold food, it should also be noted when it is used to hold oil. Because polyethylene is soluble in oil, if it is stored for a long time, the color and taste of edible oil will also change, and even cannot be eaten, which is harmful to health.

Compared with previous years, this year is a miracle year, because there is no time comparable to this year. Just this year, our plastic buckets have made a new breakthrough, and we have made changes in quality! It has achieved what has been desired in recent years. At present, the plastic barrels of our factory have a long service life. Under the conditions of normal filling, transportation, loading and unloading, the warranty period is 18 months. The technical parameters of the plastic bucket are strictly in accordance with the specifications, and the appearance design and product dimensions of the plastic bucket can also be customized according to the needs. Plastic barrels can be used for hot filling, and the general temperature should not exceed 60 ℃. After hot filling, the lid and stacking shall not be closed until the contents have cooled sufficiently and dropped to room temperature.

The orientation will also cause the difference of shrinkage and refractive index between the two directions of the product. In the production process of injection products, orientation is often used to improve the mechanical properties of the product in a certain direction. The orientation will also have an adverse effect on the product, making the product change its size, produce deformation or even crack in the direction perpendicular to the orientation due to the process of de orientation in the working process). In view of this situation, necessary treatment such as heat treatment should be carried out in advance after the molding of the work in progress, to create the necessary conditions for the reorientation of the oriented molecules, and to avoid the "freezing" of the molecular chain orientation in the work in progress, which brings about the above drawbacks during the injection, extrusion and other molding processes, the material molecular chain only produces uniaxial orientation. Uniaxial orientation has been fully applied in the production of plastic single fiber and film, which is used to improve the strength of single dimensional length direction and the strength of film in a certain direction. Biaxial orientation can improve the strength in all directions of the film plane, and also can improve the strength of the plexiglass plate. 5) Hygroscopicity Hygroscopicity refers to the tendency of plastic materials to absorb water from the air. Some plastics, such as polyamide and phenolic plastics, have an obvious moisture absorption tendency due to the hydrophilic group of resin molecular chain 1.
