分析影响木箱包装箱质量的主要因素是什么?

What are the main factors that affect the quality of wooden cases?

1、引起湿涂层白化

1. Cause whitening of wet coating

当木材单调不良,木材中的水分会跟着稀料蒸腾的作用而进入涂层,出现白化现象。水分不能释出还会因雾状影响油漆透明度。

When the wood is monotonous and poor, the moisture in the wood will enter the coating with the effect of thinner transpiration, resulting in whitening phenomenon. Water can not be released, but also because of fog affect the transparency of the paint.

2、产生针孔、气泡

2. Pinholes and bubbles are produced

由于PU漆易与水分产生反应产生气体,气体逸出时会构成气泡,气泡割裂即产生针孔,构成涂膜缺陷。

Because PU paint is easy to react with water to produce gas, when the gas escapes, it will form bubbles, which will split and produce pinholes, forming film defects.

3、影响涂层单调与固化

3. Influence on coating monotony and curing

由于卡板木材含水率高,使涂层与木材的接触面处于湿度情况,影响稀料的蒸腾和树脂与固化剂的交联反应,因此也影响了涂层的单调速度和顺利固化,构成不干或单调不完全。

Due to the high moisture content of the wood, the contact surface between the coating and the wood is in the humidity condition, which affects the transpiration of the thinner and the cross-linking reaction between the resin and the curing agent. Therefore, it also affects the monotonic speed and smooth curing of the coating, and the composition is not dry or monotonic incomplete.

4、影响色泽的明显

4. Obvious factors affecting color

含水率高会影响木材的上色性,当木材含水率产生变化时,涂层会跟着木材的缩短变色而致使颜色不明显。

High moisture content will affect the color of wood, when the moisture content of wood changes, the coating will change color with the shortening of wood, resulting in the color is not obvious.

5、影响油漆的附着力

5. Affect the adhesion of paint

含水率高的木材,跟着水分的解吸,涂层会龟裂、拱起、剥离,构成附着不良。

High moisture content of wood, with the desorption of moisture, coating will crack, arch, peel, constitute poor adhesion.

分防震包装办法。关于整体性好的产品和有内装容器的产品,仅在产品或内包装的旮旯或部分当地运用防震资料进行衬垫即可。所用包装资料主要有泡沫塑料防震垫、充气型塑料薄膜防震垫和橡胶弹簧等。

Methods of shockproof packaging. As for the products with good integrity and inner container, only use the shockproof materials in the corner or part of the product or inner package. The packaging materials include foam plastic shockproof pad, inflatable plastic film shockproof pad and rubber spring.
