木制包装箱的开裂怎么处理?

来源:http://www.gtmfpack.com 发布时间:2020-06-29

1、干裂
1. Dry crack
原木端面上从髓心开裂向外进展而不到材边缘,其内部沿木射线发生裂纹,称蜂窝裂;裂纹分布在材外表上的,称外表裂纹。干燥翘棱均而引动的裂纹俗称木质包装箱干裂现象。
On the end face of the log, the crack develops from the pith center to the outside but not to the edge of the log, and the crack occurs along the wood ray inside, which is called honeycomb crack; the crack distributed on the surface of the log, which is called exterior crack. Drying warping edge is uniform and induced cracks, commonly known as wood packaging box cracking phenomenon.
2.径裂
2. Radial fracture
木质包装箱的根部经常会出现径向裂纹,并从根部向上开裂,有些包装箱还会开裂到部分活树枝。
The root of wooden packing box often appears radial crack, and cracks upward from the root, and some packing boxes will crack to some live branches.
沿着径向,它穿过髓,但不开裂到当地的树皮。
Along the radial direction, it passes through the pith, but does not crack into the local bark.
3、冻裂
3. Frost crack
木质包装箱的检验方法因裂纹而异。检验尺的长度与长度之比在指定的宽度范围内测量,并以百分比表示。
The inspection methods of wooden packing cases vary with cracks. The length to length ratio of the inspection ruler is measured within the specified width range and expressed as a percentage.

4.轮裂
4. Wheel crack
木制包装箱轮裂在成材断面呈月芽形。材料表面形成纵向凹槽,轮裂成整圈。
The wooden packing box is in the shape of crescent on the section of finished wood. A longitudinal groove is formed on the surface of the material, and the wheel cracks into a whole circle.

而面对干裂我们有以下应对方法:
In the face of dry crack, we have the following countermeasures:
方法就是进行定型烘干处置,以解除木包装内部应力,使防腐木包装的内部含水率≤13%。蒸汽窑烘干或真空窑烘干是比拟幻想的处置方法,其根本道理是在规范窑里给木包装加以必然的湿度(软化木包装外表),分时分段用恰当的高温把木包装芯部的水分逼出来。防腐处置前的基材进行烘干,既能确保防腐剂有用成分的接收,又能使用木包装内部的应力,改善木包装的变形与开裂景象;防腐处置后的木包装因为防腐液经加压进入木包装内部(全湿透),需进行二次烘干(但要经阴干后,以使防腐剂有用成分固着在木包装内部)至含水率≤13%,以再次使用防腐木包装剩余的内部应力、不变尺寸、大水平地改善防腐木包装的开裂现象。
The method is to dry the wood package to relieve the internal stress and make the internal moisture content of the anti-corrosion wood package ≤ 13%. Steam kiln drying or vacuum kiln drying is a fantasy disposal method. Its basic principle is to give wood packaging necessary humidity (soften the appearance of wood packaging) in the standard kiln, and use appropriate high temperature to force out the moisture in the core of wood packaging in time and section. The drying of the base material before the antiseptic treatment can not only ensure the reception of the useful components of the antiseptic, but also use the internal stress of the wood package to improve the deformation and cracking of the wood package; Because the preservative solution enters into the interior of the wood package after antiseptic treatment (completely wet), it needs to be dried again (but after being dried in the shade, so that the useful components of the preservative can be fixed in the wood package) until the moisture content is less than or equal to 13%, so as to use the remaining internal stress of the antiseptic wood package again, keep the size unchanged, and improve the cracking phenomenon of the wood package.
