Stainless steel material surface has dust, easy to remove dirt, can use soap, weak scouring or warm water scouring. The stainless steel surface is pasted with label and film, washed with warm water, weak detergent, adhesive composition, and scrubbed with alcohol or organic solvent (ether, benzene). The grease, oil and lubricant on the surface of stainless steel shall be cleaned with soft cloth, and then cleaned with neutral scouring or ammonia solution or special scouring.
The main materials of expanded metal facade are 304304L, 316L, etc. It is mainly used for screening and filtration in acid-base environment, as sludge screen in petroleum industry, as screen in chemical and chemical fiber industry, as acid cleaning in electroplating industry.
The surface of expanded metal facade is adhered with bleach and various acids. Immediately wash it with water, then soak it with ammonia solution or neutral soda water solution, and wash it with neutral or warm water.
There are rainbow lines on the surface of expanded metal facade, which are caused by scouring or excessive oil. After cleaning with warm water, neutral washing can be used. Rust caused by dirt on stainless steel surface can be cleaned with 10% nitric acid or abrasive, or with special cleaner.
Expanded metal facade is widely used in environmental filtration because of its heat resistance, acid resistance, alkali resistance, wear resistance, durability, corrosion resistance and long service life. For example, stainless steel sieves used in sewage treatment plants can filter out stones, sediments, grass, life dregs and impurities in water. Expanded metal facade is easy to clean and can be used after cleaning with water. Therefore, it is an ideal environmental filter material.
