Chemical iron drums have good heat resistance and cold resistance, hardness, tensile strength, electrical insulation properties and toughness, and have good chemical stability, hardly dissolve in any organic solvents at room temperature, and are resistant to many Corrosion from acid, alkali and salt solutions, it also has excellent resistance to environmental stress cracking and thermal stress cracking, high surface hardness, and good dimensional stability. Chemical iron drums are easy to use, economical and durable. With the development of internationalization, plastic drums have gradually become the mainstream product for liquid packaging. It can contain Class II and Class III dangerous goods. The density of liquid containing Class II dangerous goods is 1.5g/cm3, and the density of liquid containing Class III dangerous goods is 1.8g/cm3. The product structure is reasonable, firm and strong, can be directly loaded and unloaded with a forklift, and can be stacked and stored.
The plastic container is light and not fragile. Most of the chemical plastic buckets, plastic pots and bottles used for daily food storage are made of polyethylene or polypropylene, of which polyethylene is more common. Polyvinyl chloride can also be made into barrels, basins and other containers, but like film, it cannot hold food, especially oil and wine. There are also pulse-formaldehyde plastic commonly known as "electric jade" and melamine-formaldehyde plastic commonly known as "melamine", both of which contain formaldehyde. In the production process, if the polymerization is not good, free formaldehyde may appear in the tableware. Formaldehyde is a very toxic substance. If mixed into food, it will seriously harm human health. Therefore, it is necessary to use good-quality "electric jade" and "melamine" tableware and containers. For inferior products, the relevant departments should strictly control them to prevent them from being released. Although the polyethylene container can be used to hold food, it must be used to hold oil. Since polyethylene is soluble in oil, if stored for a long time, the color and taste of cooking oil will change, and it may even be inedible, which is harmful to health.
