20L plastic bucket has the characteristics of light texture, good toughness, good sealing and no rust, so we can use it for the packaging, storage and transportation of liquid, especially for the packaging of special dangerous goods. The sealed characteristics of 20L plastic bucket are fully developed. The 20 liter plastic bucket has the characteristics of corrosion resistance and good compression resistance. We can use it in the packaging of dangerous goods requiring heat preservation, moisture-proof, pressure resistance and corrosion resistance.
The 20 liter plastic bucket can be divided into two types: thermosetting and thermoplasticity. The former can not be described and used from scratch, and the latter can be repeatedly produced. There are basically two types of structure of plastic polymer: one is linear structure, and the polymer compound with this structure is called linear polymer compound; the other is body structure, and the polymer combination with this structure is called body polymer compound.
The material of the 20 liter plastic bucket is mostly made of polyethylene, polyester and other plastics by blow molding. It is mainly used to hold glacial acetic acid, tert butyl peroxide, dangerous petroleum goods, and acid-base corrosive drugs. It has excellent properties, it is not fragile, rust, light and other characteristics, and oil resistance, corrosion resistance is good. Use anti-corrosion test: when testing the anti-corrosion of 20 litre plastic bucket, put the barrel in corrosive chemicals, and then keep the temperature of corrosive chemicals at 75 ℃ and immerse for 48 hours, the barrel body shall not have any cracking, blistering or deformation.
Remove the dirt on the damaged surface of the 20 liter plastic bucket: usually wipe the dirt with a rag first, and then scrape out the new slag with a knife. If there is any oil stain, remove the oil with hot alkali water first, then wash the alkali solution with clean water, and then scrape off the surface with a knife. When mending the cracks, cut a piece of the same kind of plastic that is slightly longer, wider and not aged than the cracks. Do you want to clean the surface, stick it all out in order, and then press it again with a wet cloth to make the bonding closer.
