Reasons and maintenance methods for the cracking of local material enclosures

Many customers and friends have reported that the fences they bought in other places will crack, but there is no such situation in the fences we bought. In fact, in many cases, it is not because of the poor quality of the fences. , but it is caused by multiple reasons, and the cracking of the general enclosure rarely occurs. If some of the enclosures are cracked, of course there are many reasons. The editor below will analyze with you the reasons that may cause the enclosures to crack and the maintenance methods of the enclosures. 1. The swelling rate of the enclosure material is high, and the board is easy to absorb moisture and expand after being damp, which will cause the wall to crack. 2. The enclosure material has high hardness and poor impact strength, and the wall is prone to cracking when damaged. 3. The water absorption rate of the enclosure material is high, which can easily lead to cracking of the seams and peeling off of the surface decoration. 4. The material is brittle and has low compressive and flexural strength, which leads to cracking of the enclosure. So how should we maintain the enclosure? First of all, pay attention to enclosure and dust removal. The dust in the enclosure of the construction site is flying and accumulated, and a layer of floating dust is easy to fall on the enclosure equipment. It will affect the color of the construction site, resulting in some damage to the iron protective film. Therefore, the equipment of the wild cast iron enclosure should be scrubbed regularly, and it is better to wipe it with a soft cotton cloth. Second, pay attention to moisture-proof. If it is normal outdoor air humidity, you can rest assured to beautify the rust resistance of the fence. If it is in foggy weather, use a dry cotton cloth to wipe the water droplets on the fence; if it is rainy, wipe the water droplets in time after the rain stops. Because acid rain has been raging in most parts of our country in recent years, the rainwater on the remaining fence should be wiped off immediately after the rain. Finally, it should be cleaned frequently. Always keep the enclosure surface clean. When scrubbing, choose soft gauze or cotton cloth to avoid scratching the beautiful appearance of the enclosure. In addition, no matter how serious the pollutants are cleaned, no cleaning agent should be added to the cleaning solution, because the cleaning agent will reduce the friction of the cleaning brush and the cleaning surface, which will affect the cleaning effect.
