What is the reason for the peeling of the paint on the floor surface?
2. The second reason for the paint peeling is that some paints have poor adhesion and cause paint peeling. There are two reasons for poor adhesion:
(1) Some species of wood contain extractive components, such as phenolic compounds, which have a polymerization inhibitory effect on the polymerization reaction of free radical-initiated UV coatings, resulting in poor adhesion of the paint film and delamination of the paint film. Severe peeling occurs.
(2) Before the paint on the wooden floor, the moisture content of the floor is too high (moisture content is more than 12%). Because the moisture content is too high, although the surface is coated with paint, when the external environment changes, the water inside the wood will evaporate outwards. Internal stress changes, resulting in uneven force, resulting in cracking, peeling and other serious quality accidents.
Although you mentioned the phenomenon of paint peeling in the letter, because I did not go to the scene to observe, it is difficult to determine which of the reasons is caused. I cannot assert here, please forgive me.

All aluminum alloy material has strong plasticity and never rusts. Fluorocarbon baking powder is delicate, smooth, and long-lasting without fading. The product is intelligently matched with various smart devices, making it a minimalist, luxurious, and youthful fashion design style.
Advantages of aluminum doors:
Strong and durable: Aluminum alloy has high strength and hardness, can withstand the collision and wear in daily use, and has a long service life.
Corrosion resistance: Aluminum will naturally form an oxide film in the air. This oxide film can effectively prevent aluminum from further oxidation and corrosion, making it stable and not easily damaged in environments such as moisture, acid and alkali.
Good fire resistance: Aluminum alloy has good high temperature resistance, which can play a role in fire prevention to a certain extent and increase the safety of living.
Good sealing: Aluminum doors can be equipped with high-quality sealing strips to effectively improve the sealing performance of the door, and have significant sound insulation, heat insulation, and dustproof effects.
Various styles: Through different surface treatment processes and designs, a variety of colors and styles can be achieved to meet different decoration styles and personal preferences.
Environmental protection: Aluminum is a recyclable material and conforms to the concept of environmental protection.
