How to clean the litchi surface ?
Generally there are machine oil pollution, pigment pollution, fast food oil pollution, universal glue, ink, asphalt, paint, carbonate, silicate and other pollution, etc. are more common. Usually use trapezoid type 30S bush hammer rollers and chemical oxidant and other cleaning.
Stain characteristics analysis and the choice of cleaning methods
Asphalt: is a brown-black organic gel-like material, including natural asphalt, petroleum asphalt, shale asphalt and coal tar asphalt and other four kinds. The main components are asphaltene and resin, followed by high boiling point mineral oil and a small amount of oxygen, sulfur and chlorine compounds. Glossy, liquid, semi-solid or solid state, brittle at low temperatures. So generally the permeability on the fire plate is not too strong. So it is more effective to use 240mm buan hammer for diamatic grinder suppliers.
Universal adhesive: the main components are neoprene, resin, mixed with a variety of solvents. General solid content is high, easy to become thin (thick) film curing on the stone surface. Not easy to penetrate, generally bonded to the surface of the granite capillary pores more tightly. Thus, the use of satellite type bush hammer plate is more effective.
Ink: the main raw materials for the charcoal smoke, glue, additives and solutions, etc., generally through the mechanical processing. There are many kinds of charcoal smoke, including various mineral plants and animal raw materials by burning or thermal decomposition. Gum, in addition to animal gum, mostly plant gum (gum Arabic) or a variety of synthetic gum such as acrylic glue, polyol resin, etc.. Additives are various stabilizers, penetrating agents, wetting agents, preservatives, aromatic agents and so on. Therefore, the use of chemical oxidants to rinse more effective.
