You can rest assured to buy Double-sided Spray Luggage Glue from our factory.
Double-sided spray luggage glue is a common bonding technology used in the luggage manufacturing process. It involves using a glue sprayer to evenly spray glue on both sides of the luggage material to achieve a firm bond of the material. The following is a detailed analysis of double-sided spray luggage glue:
Spray glue type and characteristics
Spray glue type:
There are many types of spray glue on the market that are suitable for luggage manufacturing, including water-based spray glue, hot melt glue, etc. Among them, water-based spray glue is popular because of its non-toxic and environmentally friendly, low odor, good initial adhesion, and high bonding strength.
Features:
Strong initial adhesion: The spray glue can quickly form initial adhesion after spraying, ensuring that the materials can be tightly bonded at the initial contact.
Fast speed: The glue sprayer can quickly and evenly spray glue on the surface of the material to improve production efficiency.
Drop-resistant and durable: The cured spray glue has good drop resistance and durability, which can ensure that the luggage is not easy to open or damage during use.
Double-sided spraying steps
Preparation stage:
Remove the accumulated water from the air compressor and ensure that the air pressure is within the appropriate range (such as 6-8kg).
Check whether the performance of the spray gun is intact and ensure smooth spraying.
Prepare the luggage materials to be bonded and ensure that their surfaces are clean and free of oil stains, water stains, stains and dust.
Spraying operation:
Use a glue sprayer to spray the glue evenly on both sides of the luggage materials.
The spray gun and the adherend should maintain an appropriate angle (such as 45° or vertical) and a distance of about 50 cm to ensure that the glue can be evenly distributed on the surface of the material and the thickness is consistent.
Be careful to avoid the phenomenon of no glue or glue accumulation to avoid affecting the bonding effect.
Airing and bonding:
The sprayed material needs to be aired for a period of time (such as 2-15 minutes). The specific airing time depends on the type of glue spray and the characteristics of the material. During the airing process, the glue will gradually reach a state of 70% to 80% dry. At this time, the glue layer will be sticky but not sticky when touched by hand.
During the airing process, for the bonding surfaces with curved parts, large bearing surfaces or heavy stress points, ensure that both sides are sprayed and dried to 70% or 80% before bonding.
Apply appropriate contact pressure during bonding to ensure the bonding effect.
Precautions
During the use of spray glue, attention should be paid to ventilation to avoid long-term inhalation of glue odor.
Spray glue cans should be placed out of reach of children to prevent accidents.
Before discarding the spray glue can, the contents should be completely sprayed in an unmanned place and the empty can should be handled in an appropriate manner.
