《GB/T 33039-2016人造板生产用回收木材质量要求》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
1. Background and significance of standard formulation
With the increasing shortage of wood resources and the enhancement of environmental protection awareness in my country, the application of recycled wood in the production of wood-based panels has gradually received attention. The introduction of GB/T33039-2016 standard aims to standardize the quality requirements of recycled wood, promote its recycling and reduce excessive dependence on forest resources.
2. Comparison of standard frameworks
| Standard dimensions | GB/T33039-2016 | LK/RT58-2020 | Comparative analysis |
|---|---|---|---|
| Definition of terms | Clear definitions of recycled wood, mixed materials, etc. | Added new classification standards for hazardous substances | Complementary relationship, LK standard supplements the definition of hazardous substances |
| Classification method | Divided into logging residues, production and processing residues and post-consumer recycled wood according to source | Added classification by purpose | LK standard pays more attention to actual application scenarios |
3. Analysis of technology evolution
Moisture content control:GB/T33039-2016 stipulates that the absolute moisture content shall not exceed 50%, but does not specify the detection method. Subsequent standards (such as LK/RT58-2020) supplemented the dynamic moisture content monitoring technology and improved the quality control level.
4. Implementation suggestions
Case analysis: Application of recycled wood in a certain man-made board enterprise
Enterprise background:A medium-sized man-made board production enterprise with an annual production capacity of 50,000 cubic meters.
Implementation steps:
- Establish a quality inspection system for recycled wood
- Purchase recycled wood that meets the standards
- Optimize processing technology to adapt to the characteristics of recycled wood
- Regularly monitor product quality and improve
Implementation effect:By applying the GB/T33039-2016 standard, the company reduced the cost of raw materials by about 15% and reduced its dependence on virgin wood.
