Increasing the thickness of the epoxy floor paint film, if the epoxy floor paint film is thick, there will be no obvious shrinkage hole formation. If the floor paint film is thin, it will be easy to form shrinkage hole problem. All walks of life have increasingly high requirements for cleanliness. One of the most important reasons is the shrinkage of the floor caused by the early epoxy floor paint painting construction. At this time, people may ask, how is the shrinkage of the floor formed? Next, let's analyze and analyze the causes of this problem during construction. Nowadays, in this society, no matter what you eat out, what you care about is a clean and unclean thing that you will never touch. For example, today's factory workshops: factory workshops are divided into cleanliness levels according to certain areas, and most of the requirements are dust-free workshops. However, in some workshops, no matter how clean up there are always some debris particles, which is why?
Article 1: First of all, we should consider the construction environment at that time. If there are dust, building slag, paint mist and other substances in the construction environment, it is unavoidable that there will be floor quality problems.
Article 2: Spraying tools and equipment are not clean, and foreign bodies are mixed into the paint. Spraying is contaminated by paint mist of different coatings, oil contamination in compressed air and dry polishing residue.
Article 3: The use of poor quality coatings results in high surface tension, poor leveling and release of air bubbles, which greatly reduces the shrinkage resistance of the coatings themselves.
In view of the above phenomena, how can we effectively avoid such problems in construction?
Before construction, the floor surface should be thoroughly cleaned. To ensure a good painting environment, there should be no dust, oil mist and paint mist in the air.
The equipment, tools, hoses and other articles used during the painting construction must be cleaned up. The auxiliary materials must not contain harmful substances, especially organosilicon compounds, which lead to shrinkage of coatings. (Tip: No bare hands, dirty gloves and dirty cloth are allowed to touch the surface.)
Choose coatings with good quality and low sensitivity to shrinkage. Before spraying, the ground should be thoroughly polished and cleaned up.
