Introduction

In-depth interpretation of the standard for determination of total solid content of forestry biomass raw materials

1. Background and significance of standard formulation

GB/T 35905-2018 "Analysis method for forestry biomass raw materials - determination of total solid content" is China's first standard specifically for the determination of total solid content of forestry biomass raw materials. With the increasing global attention to renewable energy and green technology, forestry biomass, as an important sustainable resource, plays a key role in the fields of energy, materials and environment.

The formulation of this standard fills the gap in the field of forestry biomass analysis methods in China, provides unified technical specifications for related industries, and ensures the consistency and reliability of data. At the same time, this standard also lays the foundation for international technical exchanges and cooperation.

2. Core principles of total solid content determination

The total solid content refers to the mass fraction of the absolute dry matter remaining after the sample is heated to constant weight at $105~^{\circ}\mathrm{C}$. Its core principle is based on thermogravimetric analysis, which calculates the solid content by measuring the mass change of the sample at high temperature.

Method A: Traditional drying method, suitable for samples with stable chemical properties.
Method B: Moisture analyzer determination method, suitable for rapid determination.

3. Method comparison and implementation points

Dimensions	Method A	Method B
Scope of application	Samples with stable chemical properties	Samples with stable chemical properties and a volume density of not less than $0.1~\mathrm{g/cm^{3}}$
Instrument requirements	Analytical balance (accuracy 0.0001g), Electric drying oven	Moisture analyzer (infrared heating source), beaker
Operation steps	Bake for at least 3 hours and weigh after cooling	Quick determination, the end point mass change rate is less than 0.05% per minute

4. Practical application case analysis

Case background:A forestry company needs to determine the total solid content of a batch of pine sawdust.

Implementation steps:

Sampling in accordance with GB/T35820—2018 to ensure sample representativeness.
Use analytical balance to weigh the initial mass of the sample $m_{\mathrm{i1}}=2.0~\mathrm{g}$.
Use method A and dry at $105~^{\circ}\mathrm{C}$ until the difference between the two weighings is less than $0.0003~\mathrm{g}$.
Calculate the total solid content: $$\mathcal{w}={\frac{m_{\mathrm{f3}}-m_{\mathrm{t}}}{m_{\mathrm{i1}}-m_{\mathrm{t}}}}\times100\%$$

5. Implementation suggestions

Operation points:

Ensure that the equipment is calibrated, especially the analytical balance and moisture analyzer.
Prepare the sample strictly in accordance with the standard requirements to avoid contamination.
Pay attention to controlling the drying time to prevent over-drying from causing changes in chemical properties.

Equipment maintenance:

Regularly clean the electric drying oven and moisture analyzer.
Check and replace the desiccant in the dryer to ensure its effectiveness.

Sample management:

Do a good job of sample identification to ensure traceability.
For abnormal results, retest in time and record the reasons.

6. Analysis of standard technology evolution

From GB/T 35814-2018 to GB/T 35905-2018, it can be seen that the forestry biomass standard system has been gradually improved. In the future, with the advancement of technology and changes in application requirements, the total solid content determination method will become more intelligent and automated.
