Tip: ↑↑ Click on "Stone Research Association" to pay attention.

With the continuous improvement of people's health awareness, toilets in public places such as shopping malls, hospitals, schools and office buildings are equipped with hand sinks. It can be said that the washbasin has become an area that people will contact after entering public places, so it is very important for cleaning and property friends to keep the washbasin clean and beautiful. Generally speaking, these sinks are made of natural stone or artificial stone. I often get calls from cleaning and property friends, many of which are about white spots or white spots on the countertop of the bathroom sink. There is no luster after a period of use, and so on. Today, I will discuss with you the problem of "whitening the countertop of sink". Why does the stone on the sink table turn white? What are the main pollutions?

The reason why the sink is white:

1, alkaline or acidic cleaning agent pollution. Such as hand sanitizer, soap, toilet cleaner and other cleaning products, dripping on the stone table will slowly corrode the stone surface, and the stone surface will turn white or even lose its luster.

2. Water and water-based pollutants. Because the surface of stone was corroded by alkaline cleaning agent, the protective layer of stone was destroyed, and water and water-based pollutants penetrated into the stone, resulting in rust yellow and black on the board.

Today, I will share a general solution for whitening sink countertops for your reference.

Solution:

1, the corrosion situation is serious, with white spots or obvious white spots, which need to be renovated and recrystallized and hardened. The specific steps are as follows:

(1) Use dry grinding plate and portable polishing machine to grind step by step. By grinding, the surface layer corroded by alkaline substances can be cut off, thus forming a new flat working surface on the sink.

(2) Brush with osmotic protective agent. Brushing protection can effectively prevent water and water-based pollutants from infiltrating into table stone.

The interior of the material makes it sick; Secondly, coating protective agent can greatly improve the effect of recrystallization hardening treatment on stone surface.

③ crystallization and polishing. Polishing with white scouring pad and JT-3 10 Ghana rice flour (1: 1) twice can improve the anti-pollution protection effect of the countertop surface, and can also reduce the whitening phenomenon caused by non-neutral detergent pollution.

4 touch up. After crystallization polishing, polishing with polishing care agent A can effectively improve the problem of dry stone surface caused by polishing and improve the color saturation of stone.

2. The corrosion is light and the color difference is not obvious, so it can be directly polished.

If the tabletop is smooth, you can directly touch up the paint with polishing care agent A, and the natural stone tabletop with rough surface can also touch up the paint with stone coloring care agent. If you brush it directly, you can touch up the paint and return to color, which can play a protective role.
