From logs to finished boards: analysis of the entire production process of FOSB for Hubei Huasheng fragrant cedar
Product Introduction
Hubei Huasheng New Fragrant Cedar FOSB Using cedar wood as raw material
After long wood planing, drying, and screening
Mixing glue, multi-layer directional paving, preloading
Directional structural plates formed by continuous flat pressing
Strictly follow the latest standards in China
Production according to GB/T 41715-2022
01 Pre selection of materials
We strictly screen high-quality cedar trees from sustainably managed forest farms as raw materials
Chinese fir is known for its unique aroma, excellent physical properties, and stable chemical properties
Becoming an ideal choice for manufacturing high-quality oriented strand board
According to industry standards and the company's internal quality control system
We have established strict material selection standards
And tested through professional equipment
Ensure the accuracy and reliability of material selection
02 Particle production section
Adopting advanced Canadian long material planer
Cut the cedar wood to a length of 100-120mm
Planes with a width of 20-50mm and a thickness of approximately 0.6mm
And fine cedar material with a particle size of about 1.2mm
This precisely controlled particle size
Provided strong guarantee for the efficient progress of subsequent processes and the excellent performance of products
03 Drying section
We use the GTS thermal power plant and Diefenbach drying production line from the United States
Quickly and uniformly dry wet shavings
By precisely controlling the drying temperature and time
Ensure that the moisture content of the shavings remains stable at around 2%
This moisture content standard
It is the best value obtained based on years of production experience and scientific research
Can effectively improve the durability and stability of the board
04 Screening section
Utilizing advanced Par particle grading and screening equipment
Fine sieving of dried shavings
By setting precise sieve aperture and vibration frequency
Ensure that every planed flower meets production standards
During the screening process, unqualified shavings will be automatically removed
So as to ensure the overall quality of the product
05 Glue application section
In the glue application section, we use Diefenbach's glue mixing system
Spray MDI glue, paraffin lotion, curing agent and other additives evenly on the shavings
Design of guide strips and atomizing heads embedded on the inner wall of the glue mixing machine
Ensure thorough mixing and uniform application of wood shavings and adhesive solution
This step not only improves the strength and stability of the board
It also extends the service life of the product
06 Paving section
In the paving section, we adopt mechanical directional paving technology
Accurately lay the glued shavings in a certain direction to form a five layer structural slab embryo
The paving equipment uses the principle of airflow to pave the upper and lower surfaces into a fine surface structure
The middle two layers of shavings are arranged horizontally
The core layer shavings are arranged longitudinally
This criss crossing pattern of shavings makes Hubei Huasheng New Fragrant Cedar FOSB
Has ultra-high dimensional stability and static bending strength
Both the board surface and the board edge have strong nail holding force
07 Hot pressing section
Hot pressing is one of the key processes in the production of oriented strand board
We use Diefenbach's continuous flat pressing and hot pressing equipment
Compact the paved slab to the predetermined density under high temperature and high pressure
The board after hot pressing treatment
Not only does it have excellent physical properties and stable structural strength
It also has good deformation resistance and durability
08 Post processing section
In the post-processing section, we process the hot pressed sheet metal
Perform fine processing such as edge alignment, cross cutting, flip cooling, and specification cutting
Through strict inspection and grading system
Ensure that every board meets quality standards
Finally, we send the finished boards to the warehouse for storage and shipment
After a series of complex processes and strict quality control measures
We ultimately created high-quality and stable performance cedar FOSB products
