The production process and material selection of laminated sheets are the key to ensuring their environmental friendliness
The production process of laminated board mainly includes the following steps:
Raw material cutting: The raw materials of the building template are obtained by cutting the logs in layers, and the logs are cut and rotary in the horizontal plane according to a certain layer thickness, and then cut into the same proportion of wood layers, and remove the impurities on the surface.
Drying, drying treatment: The wood layer after cutting and rotary cutting contains large moisture, which needs to be dried by a wood dryer, and the dried wood layer needs to be placed naturally for 2-3 days to ensure its toughness.
Gluing and laminating treatment: multi-layer wood planks are bonded together by gluing, and a special glue rolling machine is set up to evenly coat the front and back of the wood plank, and then cover 6-10 layers flatly.
Hot pressing forming: The formwork layer laid by gluing is flattened by hot pressing process, the traditional heating method uses boiler water to conduct heat, and the modern equipment adopts electric heating 1.
Painting, trimming and packaging treatment: The template that has been hot-pressed may have a little dislocation and irregular corners, and it is necessary to trim and spray waterproof paint to ensure its service life and storage time.
Eco-friendliness
The production process of laminated board has the following environmental characteristics:
No solvent and exhaust gas discharge: There is no solvent and exhaust gas discharge in the production process of laminated board, and there is no need for paint drying, which is less polluting to the environment.
Low energy consumption: Since the printing plastic film and lamination can be completed in one go, the production process has low energy consumption, fast speed and less materials.
No harmful substances: The laminated board does not use chemical coatings and inks, but uses plastic film for thermal lamination, which does not contain harmful chemicals to the human body, and solves the problem of environmental hormones and volatile organic compounds.
Resource regeneration: The laminated board does not contain harmful substances such as phthalic acid and phthalates, and can be fully used with renewable resources to reduce the production of carbon dioxide, and no dievil causes are produced when resources are regenerated.
The choice of environmentally friendly materials
To further ensure the environmental friendliness of the laminated board, the following materials can be selected:
Renewable Resources: Laminated panels made from renewable resources can reduce their impact on the environment.
Non-toxic materials: Choose materials that do not contain harmful substances such as phthalic acid and phthalates.
Low-energy materials: Choosing materials with low energy consumption can reduce energy consumption and environmental pollution.
