《GB/T 40630-2021木材刻痕防腐处理技术要求》由TC41（全国木材标准化技术委员会）归口，TC41SC1（全国木材标准化技术委员会基础标准分会）执行，主管部门为国家林业和草原局。
Introduction
Analysis of core technical requirements of the standard
| Technical indicators | C4.1 Environmental requirements | C5 Environmental requirements |
|---|---|---|
| Sapwood penetration rate | ≥90% | ≥95% |
| Heartwood penetration depth | ≥5mm | ≥10mm |
Key parameters of notching process
The standard stipulates that the notch spacing should be controlled within class=instrument>35-55mm along the grain, 16-20mm vertically, depth must be >3mm and not exceed 15% of the thickness. Laser scoring must ensure uniformity of cracks.
Implementation and application suggestions
Maritime terminal case: After mechanical indentation treatment of Massonia pine, the penetration depth of ACQ preservative reached 12mm, meeting the 10-year protection requirements of C5 seawater environment.
Main points of quality inspection
- Material evaluation: According to GB/T4822, second-class product standard
- Scratch detection: Use 1mm steel tape measure to measure the distance
- Preservative retention: Refer to GB/T22102 chromatography analysis method
