1, rust spots
The key to preventing rust spots is to perform effective surface treatment after stone processing to prevent the iron-bearing minerals from oozing out of the surface after oxidation. Generally, oil-based protective agents are used.
The rust stain is mainly used as a rust remover. However, since the rust remover is mostly acidic, it is necessary to test the acid-resistant stone such as marble and dolomite before use, and if necessary, add water to dilute.
2, water spots, wet marks
The prevention of water spots is mainly to inject resin to make the stone waterproof, to prevent the moisture in the air from coming into contact with the internal materials of the stone or cement, and to reduce the chemical reaction conditions.
The treatment of water spots mainly uses the infiltration dye to change the color of the original stone. The "wet marks are not dry" can be regarded as a major problem in the international stone conservation.
3, Baihua phenomenon, commonly known as tears
The prevention of Baihua phenomenon is mainly to treat the stone with six sides after the stone processing with osmotic protective agent.
The main problem of dealing with Baihua is to rinse the surface of the cleaned stone with water to make it neutral. After drying, the surface and joints of the stone are cured.
Rust remover and detergent should use high oxygen, mild formula, remove rust stains, tea stains, straw stains, yellow spot stains and metal oxides on the stone, and must not hurt the stone.
Milling Type Aluminium Handles
A good milling type Aluminium Handle has fine workmanship, no defects and good texture. Feel very comfortable, the owner can choose the handle through electroplating or electrostatic painting. China Milling Type Aluminium Handles have better wear and corrosion resistance. In addition, it also depends on the tension of the milling handle. Generally, the door handle shall be able to accept a tensile force of more than 6kg. In addition, the surface of the milling handle is painted, which has beautiful luster and is not easy to fade and rust.
