防腐木是用壓板壓制而成的人造板。如果防腐木材的含水率控制不好，往往會出現一些不良情況，危害我們的應用。具體危害是什么？下面
山東防腐木生產廠家將為您介紹。
Antiseptic wood is a kind of wood-based panel made by pressing with pressing plate. If we don't control the moisture content of wood, we often have some bad effects. What are the specific hazards? Next, Shandong anti-corrosion wood manufacturers will introduce to you.
1、危險涂料的干燥和固化
1. Drying and curing of hazardous coatings
由于防腐木材含水率高，涂料與防腐木材的接觸區域處于潮濕狀態，危及稀釋劑的蒸發和樹脂與固化劑之間的化學交聯反應。因此，它也會危及涂層的干燥速度和完全固化，導致不干燥或不完全干燥。
Due to the high moisture content of the wood, the contact area between the coating and the wood is wet, which endangers the evaporation of diluent and the chemical cross-linking reaction between resin and curing agent. Therefore, it can also endanger the drying rate and complete curing of the coating, resulting in non drying or incomplete drying.
2、油漆附著力受損
2. Paint adhesion damage
隨著水分的解吸，涂層會開裂、膨脹和分離，導致附著力差。
With the desorption of water, the coating will crack, expand and separate, resulting in poor adhesion.
3、它會導致真菌的生長
3. It causes fungi to grow
因為水分含量高會導致腐朽真菌、霉菌和變色細菌的生長，從而導致防腐木材的腐爛和損壞。
Because high moisture content will lead to the growth of decaying fungi, molds and chromotropic bacteria, which will lead to the decay and damage of preservative wood.
4、使濕涂層變白
4. Whiten wet coating
防腐木材干燥不好時，木材中的水分會在稀釋劑蒸發的作用下進入涂料，這往往會導致木材變白。如果濕氣不能釋放，油漆的透明度會因霧而受損。
When preservative wood is not dried well, the water in the wood will enter into the coating under the evaporation of diluent, which often leads to the whiteness of wood. If the moisture cannot be released, the transparency of the paint will be damaged by fog.
5、導致針孔和氣泡
5. Causes pinholes and bubbles
因為聚氨酯涂料容易與水發生反應，產生氣體。當氣體逸出時，會產生氣泡，導致針孔和薄膜缺陷。
Because polyurethane coating is easy to react with water and produce gas. When the gas escapes, bubbles will be produced, leading to pinholes and film defects.
6、傷害獨特的顏色
6. Unique colors
含水率高會損害防腐木材的著色性。當防腐木含水率變化較大時，涂料會隨著防腐木的坍塌而變色，造成色澤不均勻。
High moisture content will damage the colorability of preservative wood. When the moisture content of the wood changes greatly, the paint will change color with the collapse of the wood, resulting in uneven color.
