For customers, the quality of the trash can is what they are most concerned about. When we choose the trash can, how should we pay attention to the quality of the trash can? The editor believes that the material of the trash can is the key factor affecting the quality of the trash can. The editor will share with you the relevant knowledge of trash can manufacturing materials, hoping to help you buy trash cans.

1. 201 stainless steel

Due to the tough texture of steel, wear resistance and compression, steel-wood trash cans, stainless steel trash cans, and fiberglass trash cans with steel as the main material are often the best choices for outdoor trash cans.

201 stainless steel belongs to the 200 stainless steel series. The 200 stainless steel series was first developed in the United States as a substitute for the 300 series stainless steel during World War II. China's 200 series stainless steel mainly includes J1, J3, J4, 201, and 202. Later, steel grades such as 200 with lower nickel content control appeared. Among them, 201c stainless steel is the extended steel grade of 201 developed by individual steel mills in China. It is to continue to reduce the content of nickel and increase the content of manganese on the basis of 201. The national standard grade of 201 is: 1Cr17Mn6Ni5N

201 stainless steel has the characteristics of acid resistance, alkali resistance, high density, no bubbles and no pinholes in polishing.

2. Galvanized sheet

Galvanized sheet is also one of the important materials for garbage bins and fruit shell bins

Galvanized sheet refers to a steel sheet coated with a layer of metallic zinc to prevent the surface from being corroded. Galvanizing is an economical and effective anti-corrosion method, and this process is used for about half of the world's zinc production. In the United States, the first continuous hot-dip galvanized strip production line was built in 1937, and the first continuous electro-galvanized strip production line was built in 1942. It has been more than 60 years since it entered industrial production. The main types of galvanized sheets are hot-dip galvanized steel sheets, alloyed galvanized steel sheets, electro-galvanized steel sheets, single-sided and double-sided differential galvanized steel sheets, and alloy composite galvanized steel sheets. The main domestic production plants are Alltong, Wuhan Iron and Steel, Anshan Iron and Steel, Baosteel Group, China Metallurgical Hengtong, Shougang, Panzhihua Iron and Steel, Handan Iron and Steel, Maanshan Iron and Steel, etc.; the main foreign producers are Japan, Germany, Russia, France, South Korea and so on.

The biggest advantage of coated steel sheet is its excellent corrosion resistance, paintability, decoration and formability. Countries around the world are studying how to improve the coating process and then improve the quality of the coating, that is, corrosion resistance, anti-powder spalling, coating and weldability. The inner liner of the garbage bin and the fruit shell box is mostly made of galvanized sheet, which has good corrosion resistance and corrosion resistance. There are also galvanized sheet garbage bins made of galvanized sheet for the outer shell.

3. FRP

1. Glass fiber reinforced plastics (GRP or FRP-glass fiber reinforced plastics) are commonly known as glass fiber reinforced plastics in my country. They are the most used composite materials today, accounting for more than 90% of the composite material output in the modern sense.

2. FRP, because of its high strength, light weight, corrosion resistance, heat preservation, sound insulation, long life and other advantages, is widely used in aerospace, wind power generation, yacht fishing boats, auto parts and other fields.

3. Product Chinese name: FRP waste bin Product English name: FRP waste bin

Product introduction: It has the characteristics of corrosion resistance, high strength, easy cleaning, good sealing, beautiful appearance, aging resistance, and no fading. It is an ideal appliance for urban sanitation.
