How to Choose Diamond Grinding Pads for Floor Treatment？
Especially, building materials
The diamond grinding pad
used for floor treatment should be selected according to the use experience, construction process and construction method.
According to the construction process selection: the floor treatment construction process is generally divided into leveling, coarse grinding, fine grinding, fine grinding and polishing, the use of diamond grinding pad and thick grinding pad is conducive to the ground leveling treatment, coarse grinding and fine grinding when the choice of thick grinding pad can improve the construction efficiency, fine grinding and polishing when the choice of thin grinding pad will have a better effect.
Resin polishing pads
According to the choice of construction methods: the construction methods of floor treatment are generally divided into dry mill treatment and water mill treatment.Concrete dry grinding pad should be selected for dry grinding treatment, while water grinding pad should be selected for water grinding treatment. The service life of concrete dry grinding pad for water grinding treatment will be slightly shorter, and the high speed dry throwing effect of thin grinding pad is better when the floor is polished.
After spraying or brushing the cement sealing agent, the next step is to grind and polish the floor.Since it involves the grinding of the concrete floor, it is inseparable from the discussion of dry grinding and wet grinding.So when the stone is solidified, when the dry grinding and when the water grinding?First of all, we must know what is a dry mill. "Dry mill is incomprehensible in grinding is not adding water", what is called water mill "water mill is also like the surface meaning, is to add a certain amount of water in the grinding stone grinding is called water mill."
The benefits of wet grinding concrete floor:
1. Wet grinding helps protect the environment
Wet grinding is an ancient method with a long history.Wet grinding of natural stone has been used for hundreds of years.In the early days of the polished concrete industry, the ground was wet ground.Dry milling has been a popular method of grinding in the U.S. industry for more than a decade, but with increasing environmental awareness and "green" construction requirements, wet milling is catching up again and becoming an important consideration in the bidding process.
2. Wet grinding helps to reduce pneumoconiosis
Wet grinding can effectively avoid Silicosis (also known as Silicosis, which is caused by long-term excessive inhalation of rock dust containing crystalline free silica) and reduce dust pollution caused by dry grinding.
3. Wet grinding helps to prolong the service life of the grinding disc
When grinding medium to high hardness surfaces, wet grinding and wet casting greatly extend the service life of the blade and help to achieve grinding results, cutting deeper, exposing aggregate, and cutting faster.
4. Wet grinding helps to create a matte finish
Using the wet grinding method can use a higher mesh grinding disc, a relatively matte effect, but also to facilitate the daily maintenance of the ground.The first two or three polishing processes, if water mill, can help to remove scratches left on the ground by the metal grinders.
matte
The advantages of concrete ground dry grinding:
1. Dry grinding helps to create highlights
Compared to wet grinding, dry grinding is more helpful to achieve the effect of highlighting the ground, to achieve a higher reflective rate of the ground.
The light is
2. Helps deal with soft concrete floor
The soft concrete ground consumes the hard tire pad very much, which leads to the increase of cost and the decrease of profit. If the ground is wet ground, the grinding pad will be too sharp and leave abrasion marks on the ground. The dry grinding rule is more suitable for the soft concrete ground.
So, concrete solidified floor in the end is dry ground or wet ground good?In many cases, the ideal grinding method of cement solidified floor is often the combination of dry and wet.Usually wet polishing is done after wet grinding and dry polishing is used to improve the gloss of the ground. This can both control the cost and reduce the amount of dust produced in the final stage of the high mesh polishing process is actually very small.
