Granite is the first choice for laying the ground in some households, and it is inevitable to suffer from pollution. Generally, organic oil pollution, pigment pollution, oil pollution, asphalt, paint, carbonate, silicate and other pollution, how to clean up the common pollution of granite? Let's take a look with FABULOUS editor.
rust spots
The iron element (Fe) attached to the surface of the stone or the environment undergoes oxidation reaction with water (H2O) and oxygen (O2) in the air, resulting in rust spots (Fe2O3) on the surface of the stone. ——So it is more effective to rinse with chemical oxidizer.
cement stains, lime stains
The main ingredient is carbonate and silicate dirt. ——So it is more effective to clean with an environmentally friendly acidic cleaning agent compounded with a variety of corrosion inhibitors, inorganic acids and surfactants. Do not use acid solutions of chemical raw materials (such as oxalic acid, hydrochloric acid, hydrofluoric acid, etc.). Otherwise, it is easy to cause yellowing, blackening, and whitening.
asphalt
is a brown-black organic gelatinous substance, including natural pitch, petroleum pitch, shale pitch and coal tar pitch. The main components are asphaltene and resin, followed by high-boiling mineral oil and a small amount of oxygen, sulfur and chlorine compounds. It is shiny, liquid, semi-solid or solid, and brittle at low temperature. So generally the permeability on the fired plate is not too strong. ——So the physical grinding and crushing method is more effective.
Universal glue
The main components are neoprene, resin, and mixed solvents. Generally, the solid content is relatively high, and it is easy to form a thin (thick) film on the surface of the stone. It is not easy to penetrate, and is generally tightly bonded to the pores of the surface layer of granite. Therefore, the physical grinding and crushing method is more effective.
ink
The main raw materials are carbon smoke, rubber materials, additives and solutions, etc., which are generally processed by machinery. There are many kinds of charcoal smoke, including various mineral, plant and animal materials that are burned or thermally decomposed. In addition to animal glue, most of the glue is vegetable glue (acacia gum) or various synthetic glues such as acrylic glue and polyol resin. Additives include various stabilizers, penetrants, wetting agents, preservatives, fragrances and so on. ——So it is more effective to use chemical oxidizer to rinse.
