The coating process of PVC skirting board refers to the process of evenly covering the decorative material (such as PVC film or wood grain film) on the surface of PVC skirting board through gluing, laminating, compacting, and other steps to improve its aesthetics and durability. This process includes cleaning the surface of the skirting board, gluing (cold glue or hot glue), quickly laminating the coating material, compacting, curing, or cooling to ensure that the coating material is closely combined with the skirting board to form a beautiful and durable product.
Cold glue coating is a method of bonding decorative materials (such as veneer, PVC film, etc.) to the surface of the substrate with cold glue (such as solvent-based glue or white latex) at room temperature.
Glue Type
Cold glue coating uses glue with high viscosity at room temperature, generally solvent-based glue or white latex. These glues can quickly form viscosity at room temperature, thereby bonding the wrapping material to the skirting.
Cold glue coating process
Prepare materials
Clean the surface of the skirting board to ensure it is free of dust and oil.
Glue application
Apply cold glue evenly on the back of the skirting board or covering material.
Covering
Apply the covering material (such as PVC film, veneer, etc.) to the skirting board, ensuring there are no bubbles.
Compacting
Compact the covering material using a roller or other tool to ensure a strong bond.
Curing
Allow the glue to cure at room temperature. This process may take from a few hours to a day, depending on the type of glue and the ambient temperature.
Advantages of cold glue coating
The equipment and process are relatively simple
No complex heating equipment is required, and the investment cost is low.
Wide application range
The temperature requirement is not high, and it can be operated in various environments.
High flexibility
Suitable for small and medium-sized enterprises or workshops, easy to operate.
Disadvantages of cold glue coating
Slow curing speed
It takes a certain amount of time for the glue to cure, which affects production efficiency.
Low bonding strength
Compared with hot glue coating, the bonding strength of cold glue coating may be slightly inferior.
Hot glue coating is a method of bonding decorative materials (such as wood grain film, PVC film, etc.) to the surface of the substrate by heating the hot melt adhesive to make it melt and sticky.
Glue Type
Hot glue coating uses hot melt adhesive. Hot melt adhesive melts when heated to a certain temperature and has strong viscosity. After cooling, it will solidify quickly and form a strong bond.
Hot glue coating process
Prepare materials
Clean the surface of the skirting to ensure that it is free of dust and oil.
Heating equipment
Heat the hot melt adhesive to a specified temperature to melt it.
Gluing
Use a glue sprayer or glue applicator to evenly apply the hot melt adhesive to the back of the skirting or covering material.
Covering
Apply the covering material to the skirting quickly to ensure that there are no bubbles.
Compacting
Use a roller or other tool to compact the covering material to ensure a strong bond.
Cooling and curing
Let the hot melt adhesive cool and cure, which is usually a very quick process that can be completed in a few minutes.
Advantages of hot glue coating
Fast curing speed
After cooling, hot melt adhesive cures quickly and has high production efficiency.
High bonding strength
Hot melt adhesive has high bonding strength and is suitable for high-intensity use environments.
Automated production
Suitable for large-scale production and easy-to-realize automated operation.
Disadvantages of hot glue coating
Large equipment investment
Requires heating equipment and glue coating equipment, and the initial investment cost is high.
High energy consumption
The heating process consumes a lot of energy and has high operating costs.
High process requirements
The temperature and operation time must be strictly controlled to prevent overheating or underheating from affecting the bonding effect.
Cold glue coating is easy to operate and has a low investment cost. It is suitable for small batch production, especially for small and medium-sized enterprises or workshops; it is suitable for occasions where the bonding strength requirements are not high, such as ordinary household cabinets and office furniture; and for occasions where the ambient temperature is low or unstable, heating equipment is not required, and the environmental requirements are not high.
Hot glue coating has high production efficiency and is easy to automate, making it suitable for large-scale factory production. It is also suitable for situations that require high bonding strength, such as industrial cabinets, public furniture, and other high-intensity usage environments. In high-temperature production environments, hot glue coating can better guarantee the bonding effect.
With a deep understanding of cold glue coating and hot glue coating, you can choose the most suitable coating process according to your own production needs, budget, and quality requirements to improve production efficiency and product quality.
