你知道户外防腐木为什么会开裂及变形吗?

毕节防腐木厂家

Do you know why antiseptic wood is cracked and deformed?

野外防腐木开裂变形是怎么回事?为什么野外防腐木会开裂变形?

How is the dehiscence and deformation of the field anticorrosion wood? Why does the field anticorrosion wood crack and deform?


毕节防腐木厂家,其主要运用场所为野外,其加工处置的仅有意图是为了增强木材在野外环境中反抗各自然环境以及生物侵袭的才能。但在运用过程中,不免会发作开裂变形等表象。

Bijie anticorrosive wood factory is mainly used in the field, and its purpose is only to enhance wood's ability to resist natural environment and biological invasion in the field. But in the process of application, it is unavoidable to attack the appearance of the dehiscence and deformation.


首要,因为木材的天然特性,不免会引起开裂变形等表象,所以无论木材是不是通过防腐浸渍处置,都会有此状况发作。格外在野外运用的状况下,气候环境改变很大,当木材因为气候改变等要素而发作水份的时分,体积会胀大,而当阳光照耀而发作水分蒸腾时,木材的体积又会减小。所以木材通过这种长时间不断胀大,减小的过程中,无论是不是通过防腐处置,都会因而而形成变形及开裂等表象。

First of all, because of the natural characteristics of wood, it will inevitably cause the appearance of cracking and deformation. Therefore, whether wood is treated by antiseptic and impregnation, this situation will happen. Especially in the field of the field, the climate and environment change greatly. When the volume of water changes due to climate change and other factors, the volume will expand, and when the sun is shining, the volume of the wood will decrease. Therefore, wood will form deformation and craze and other forms, whether through preservation and disposal, during this long time of continuous expansion and decrease.


毕节防腐木的木材在浸渍处置前有必要进行窑干处置,因为木材自身的水分会阻碍木材吸收防腐浸渍剂的浸透,吸收。一般来说,木材浸渍处置前的含水率在16-18%左右。

It is necessary for Bijie antiseptic wood to be treated by dry kiln before impregnation, because the moisture content of wood will prevent wood from absorbing and soaking and absorbing. In general, the moisture content of wood before impregnation is about 16-18%.


因为北欧赤松原料的天然特性,其树心布局严密,难以遭到外界生物的侵入,具有天然防腐性。因为树心有些一样能够和外表有一样的运用年限,因而开裂不影响防腐性能与布局强度!

Because of the natural characteristics of the North European red pine raw material, its tree core layout is tight, it is difficult to be invaded by the outside world, and has natural anticorrosion. Because the heart of the tree can have the same life as the exterior, so the cracking does not affect the anticorrosion performance and the intensity of the layout.


为什么二次窑干也解决不了木材的裂缝?

Why does the two kilns do not solve the cracks in the wood?


木材发作裂缝分为外界水份改变的缘由形成和由木材内应力的缘由形成。

The crack of the wood attack is divided into the origin of the change of the external water and the cause of the internal stress of the wood.


毕节防腐木“开裂”在浸渍材处置前的窑干处置中已得到有用操控,但实际上,任何窑干技术,只能削减开裂但也无法防止劈裂。但因为在野外,则无法防止再次开裂,当浸渍木暴露在阳光,木材外表枯燥速度会更快,因而也就形成开裂和劈裂,其要害缘由在于木材的外表水分蒸腾速度要大大快于其内部。

The cracking of Bijie anticorrosive wood has been effectively manipulated in the kiln dry disposal before the disposal of impregnated materials, but in fact, any kiln drying technology can only reduce cracking but not prevent splitting. But because in the field, it can not prevent cracking again. When the impregnated wood is exposed to sunlight, the drying speed of the wood will be faster, so it will form cracking and splitting. The key reason is that the outward transpiration speed of the wood is much faster than that of its interior.
