我查了一下Tanalith E (Arch Chemiclas) 和Celcure AC-500 (Protim Osmose)是我们这边用的较多的两种环保型防腐剂,这两种都明确说明了是需要真空/压力下使用的,感兴趣的话你可以去找官方资料

* M( D+ S' c' WIf TANALITH E pressure treated timber is to be painted, stained or varnished, the timber should be dried throughout the cross section. Always follow the coating manufacturer’s instructions, taking note of the recommended maximum moisture content prior to application.
