Force Methods of Ceramic Abrasive during Solidification Process

How do ceramic abrasive grain bears forces during solidification?

Ceramic abrasive grain has become a kind of decoration on the road surface. Nowadays, many residential areas will use it for paving, and it has good anti-skid effect.

When paving the abrasive particles, it is known that it takes some time for them to dry. But do you know how the abrasive particles are subjected to force during the solidification process?

• The abrasive particles are not only repelled by the solidification front but also subjected to other impact forces. In this case, the ceramic abrasive grains will undergo displacement.

  
  

• In addition to repulsion, because the droplet density in the atomization zone is very high, droplets may also be impacted by other droplets, which will cause a force that pushes the ceramic abrasive grains into the droplets.

• The solidification front of the droplets continuously approaches the abrasive particles and moves towards them, forming a capillary area near the enhanced abrasive particles.

  
  

  In this area, the road surface is subject to the repulsion force, capillary force, and liquid convective force from the solidification front of the droplets. They all push the ceramic abrasive grains out of the capillary area.

When paving the ceramic abrasive grain, a bonding agent is needed for bonding and solidification for a period of time. Now you have also understood how it is subjected to force after solidification. And before construction, the road surface should be kept clean and tidy so that a smooth road surface can be paved.

Solving the problems of water accumulation and scratches of ceramic abrasive grain

Nowadays, most of the road surfaces are paved with ceramic abrasive grains. Of course, when using them, problems of water accumulation and scratches may inevitably occur. We have good solutions to these problems.

• The material makers know that their requirements for the ground are very high. Traditional cement needs to be acid-washed before paving, and ceramic abrasive grains are also the core of construction.

  
  

• If there is full-range water accumulation, the terrain is relatively low, and appropriate drainage channels can be dug around.

  
  

• If there is partial water accumulation, acrylic materials can be filled in the water accumulation area until they no longer accumulate water. Then, the surface paint can be repainted.

  
  

• The paint should be mixed with a higher proportion of quartz sand and clear water. Especially, the mesh size of quartz sand must be controlled and not too large.

  
  

• If the mesh size of the 70~140 mesh quartz sand is too large and the proportion is too high, it will require more water to achieve good leveling performance.

  
  

  However, if the ceramic abrasive grain is not stirred evenly, scratches and visual color difference will occur. Especially when constructing in high-temperature weather, such problems are more likely to occur.

• Different construction personnel have different habits, construction steps, and speeds. Some construction personnel walk too slowly, causing sand separation on the site. Thus, when scraped, sand is sand and material is material, a scratch line will appear after drying.

The advantage of ceramic abrasive grain is that they do not produce any odor even if the temperature is high. They replace the traditional cement floor. Regular maintenance and maintenance can prevent problems such as water accumulation and scratches and prolong the service life of ceramic abrasive grains.
