What are the specific requirements for the storage environment of plastic pails of different materials
1. Polyethylene (PE) plastic pail
Temperature requirements
Suitable for storage at room temperature, the generally tolerable temperature range is - 40℃ to 60℃. Avoid long-term exposure to high temperature, especially over 60℃, otherwise the plastic bucket may deform.
For example, in hot summer weather, do not place PE plastic barrels in direct sunlight or near heat sources such as heaters and stoves.
Light requirements
Avoid long-term exposure to sunlight, because ultraviolet rays will age the polyethylene material and reduce the strength and service life of the barrel.
PE plastic barrels can be stored in a cool place or covered with sunshade cloth.
Chemical requirements
It has good tolerance to most chemicals such as acids, alkalis, and salts, but may react or swell with strong oxidizing substances and certain organic solvents such as concentrated sulfuric acid, concentrated nitric acid, benzene, etc.
When storing, avoid contact with these chemicals. If such substances must be stored, special corrosion-resistant plastic barrels should be selected.
2. Polypropylene (PP) plastic pails
Temperature requirements
It has good high temperature resistance and can be used for a short period of time at a temperature of about 100°C. The long-term use temperature should generally not exceed 80°C. At the same time, it also has a certain low temperature resistance and is not easy to become brittle at low temperatures.
For example, in some occasions where high temperature disinfection is required, PP plastic barrels may be more suitable than PE plastic barrels, but care should also be taken to control the temperature not to be too high.
Light requirements
Similar to PE plastic bucket, long-term exposure to sunlight should be avoided to prevent aging.
It can be stored indoors or in a sheltered place.
Chemical requirements
It has good tolerance to acids and alkalis, but swelling may occur for some organic solvents such as toluene and xylene.
When storing, care should be taken to avoid contact with these organic solvents.
3. Polycarbonate (PC) plastic barrels
Temperature requirements
High temperature resistance is good, and it can be used for a short period of time at a temperature of 120℃ to 130℃, but the long-term use temperature should not exceed 100℃. At the same time, the low temperature resistance is also good, and it can still maintain good toughness at low temperatures.
For example, in some occasions where it needs to be used in a high temperature environment, such as hot water storage, PC plastic barrels may be a better choice.
Light requirements
It is more sensitive to ultraviolet rays. Long-term exposure to sunlight will cause the barrel body to turn yellow, reducing transparency and strength.
It should be stored in a dark place or shielded with shading materials.
Chemical requirements
It has good tolerance to general acids, alkalis, salts and other chemicals, but for some organic solvents, such as ketones and esters, dissolution or stress cracking may occur.
When storing, avoid contact with these organic solvents.
Plastic pails f different materials have their own requirements for the storage environment. When using, you should choose a suitable storage environment according to the material characteristics of the plastic barrel to ensure the performance and service life of the plastic barrel, while also ensuring the safety of the stored substances.
