Introduction to the general cleaning methods and classification of stone
The general cleaning of stone is divided into construction cleaning and daily cleaning according to the purpose of operation, and physical cleaning and chemical cleaning according to cleaning method.
Construction cleaning
Construction cleaning is based on the stone decoration at the end of the complete performance of stone decoration effect to carry out, to ensure the quality of construction and reflect the decorative effect has an important significance. It is usually done during stone installation or after the completion of the overall project. But most builders do simple construction waste removal and stripping of stone surface dust and attached crops when they are finished. For some of the glue, paint, oil, cement residues and other difficult to remove the pollution formed during construction, or do not remove, or use some strong acid and alkali cleaning, the final results are difficult to remedy.
Construction cleaning should be a combination of physical and chemical methods. Of course, if you can use physical cleaning methods to remove dirt, try not to use chemical methods. If the construction surface is divided into walls and floors, the cleaning operation should start with the wall. First use tools such as blades and rags to remove the obvious cement slurry, paint, glue, paint and ash on the wall and other dirt, and then use a variety of corresponding cleaning agents to clean the remaining residual pollution, such as the use of rust remover to remove rust spots on the stone, the use of degreaser to remove paint and pigment pollution on the stone. Finally wipe the entire stone wall once or twice with a rag using clean water or adding some conservation agents to the water.
The construction cleaning of the ground and the construction cleaning of the wall are basically the same, the same thickness and then fine. Finally, in order to improve work efficiency and cleaning effect can use scrub machinery to carry out the overall cleaning of the ground, cleaning process should be timely use of water absorbers to absorb the sewage left on the ground.
Daily cleaning of stone
The application environment of stone is also our living environment, so it will inevitably be polluted by our daily work and life. For example, fruit juice, cola, color stains, oil stains, hand stains, dust, etc. If these common pollution can not be removed in time, over time will leave more difficult to remove stains on the stone, some will also destroy the luster of the stone surface. Therefore, people always regularly clean or clean these stone applications, and even some special occasions every day to set up a person frequently to clean or clean the stone. The daily cleaning and care of stone should follow the following principles and methods:
If the ground or wall is found to have undifferentiated liquid dirt to be timely with better water absorption paper and cotton cloth suction. If it is water-like dirt, to wipe it again with cotton cloth, if it is oily dirt, as soon as possible with absorbent paper and cotton wipe clean. If these dirtes are still permeable after wiping, then they should be cleaned with the appropriate cleaning agent depending on the nature or composition of the dirt.
The daily cleaning of stone, especially the daily cleaning of stone floor, there is no need to scrub every day, unless there are some special circumstances and occasions. For footprints and floating ash left by pedestrians on the ground, use dust push and rub.
About the equipment and materials used in the daily cleaning of stone floors. The handle-type ground-sweeping machine and the absorber are necessary, the use of the earth-sweeping machine can greatly improve the efficiency and cleaning effect, the water-absorbing machine can clean the sewage washed through the ground in a timely manner. Of course, water is still the main cleaning material. If necessary, add some cleaning agent to the water to improve the cleaning quality. Now the market often see some people are still using some strong acids or alkalis after water release as cleaning liquid, which is also the main cause of premature loss of luster and lesions of some stone, but also to produce greater pollution to the environment.
Dust pushes, mops and towels are essential tools and materials for daily cleaning or cleaning of stone floors. However, use these tools and materials as far as possible without water and with high humidity. Because on the one hand, stone contact with too much water is prone to some lesions; on the other hand, just wiped with water on the ground is more slippery, pedestrians are easy to leave footprints after; Therefore, the stone floor of the daily cleaning, to push rub combined. Push, to dry push, or make the cotton yarn push head a little moisture, or spray a little vacuum on the cotton yarn, so that the ground dust and sand particles can be cleaned up in a timely manner. Wipe, is the use of a mopping cloth or towel in a timely manner to wipe the ground on the water and liquid dirt.
Physical cleaning
Physical cleaning refers to the use of physical methods to remove contamination, dirt, and other attached crops from stone surfaces, usually with the help of specialized equipment and tools. For example, use a blade to strip dirt such as cement, glue, and paint from the stone surface;
Chemical cleaning
Chemical cleaning refers to the use of chemical agents or chemically synthesized cleaning materials, through chemical reaction processes or with the help of some special functions of these materials to remove some contamination and stains on the surface of the stone. For example, use acidic cleaning agents to remove rust from granite, use some oxidants to remove mold from stone, use some materials containing ion surfactants to remove some common contamination on stone, and so on.
