What kind of weather makes bamboo chairs fall apart?

Bamboo is abundant in the south of our country. Almost all daily necessities made of wood in the north can be replaced by bamboo in the south. Bamboo tables? Bamboo chairs? Bamboo stools? Bamboo tea tables? Bamboo. Recliners, etc.?

Are these daily necessities made of bamboo strong, beautiful, practical, and cheap? Take bamboo chairs as an example, they are both strong and smooth, and you feel cool and comfortable when sitting on them in the summer. ?Northerners who travel to the south or visit relatives sometimes bring back a few pieces of bamboo products?

But soon after returning to the north, especially in spring, these bamboo products change: there are holes in the bamboo pieces. If there is a big gap, the bamboo needle will fall out, and the bamboo chair will shake when you sit on it, making a "creep" sound. Over time, the bamboo product will fall apart and become unusable? This is not only true for bamboo products, but also for some wooden furniture shipped from the south to the north. , will also crack and deform?

It turns out that this is caused by different humidity? Not only the temperature and rainfall are different in different parts of our country, but the humidity of the air is also very different? There are many rainy days and heavy rainfall in the south of our country. There are dense lakes and ponds, crisscrossing rivers, mostly rice fields, and the temperature is relatively high, so the water vapor content in the air is high, and the humidity is high. The water content in bamboo and wood materials will be correspondingly high. Under natural conditions Furniture made under high temperatures also contains more moisture? There is less rainfall in the north, less water in the fields, and the air humidity is already low? In spring, the red sun shines brightly, the temperature rises sharply, and the evaporation is very large, but again There is drought and little rain, so the air is very dry? Due to the loss of moisture contained in the bamboo furniture shipped from the south, it will shrink, deform, crack, or fall apart and become unusable?
