What is hot melt adhesive for matters?

The hot melt glue used in mattress production is a type of fabric bonding material specifically designed for bonding components such as mattress fabrics, fillers, and springs. Its core feature is that it is applied after being melted by heating, then quickly solidifies and bonds upon cooling. It contains no solvents, offering strong environmental friendliness and ease of operation. It's a hot gule for fabric to fabric.


Where is it used?

The "UNISN" mattress fabric bonding adhesive is mainly used to tightly connect components such as the mattress fabric with the internal spring bags and between spring bags.

Who uses it?

Matters manufacturer.

How to use?

Mattress Assembly

•Mattress Adhesive Coating Machine: This equipment first heats and melts solid hot – melt adhesive into a liquid state, and then uses a pressure device to transport the liquid hot – melt adhesive to the coating head.
•Glue Sprayer: It atomizes the glue using compressed air and evenly sprays it onto the surface of the mattress fabric or spring bags through a spray gun. Then, the materials are quickly bonded by pressing them together.
•Roll Coater: The rotating roller evenly transfers the glue onto the mattress fabric. After that, the fabric coated with glue is pressed against the spring bags for bonding.

•Laminator: Its main function is to accurately bond the mattress fabric coated with glue and the spring bags, and apply a certain pressure to make them tightly combined.

Spring Bags

•Equipment heating: Load the hot melt adhesive sticks into the glue gun or melting tank, heat to the specified temperature, and wait until the adhesive is completely melted into a fluid state.
•Gluing position: Apply adhesive to the contact sides of adjacent pocket springs, with the glue line width approximately 3-5mm.

•Immediately after gluing, fit the glued surfaces of adjacent pocket springs together and apply slight pressure to ensure the adhesive layer fully contacts both pocket surfaces. Wait for a few seconds until the adhesive layer is completely cured to finish the bonding, then proceed to splice the next unit.

Usage and Precautions

•Open Time: 10 - 20 seconds

•Operating Temperature Settings: Glue melting tank: 160 - 190°C; Hose and spray gun: 150 - 180°C. Note: In cold environments, the hot - melt adhesive dissipates heat quickly, and the operating temperature of the hot - melt adhesive needs to be increased by at least 5°C.

In addition, note the following:

1.Pre - heat the glue - melting device for about 2 hours first.

2.Control the amount of glue added according to the production volume to prevent over - heating due to incomplete consumption over a long period, which may cause the glue to age and affect its adhesion. Also, avoid insufficient consumables, which may affect glue spraying.

3.After replenishing consumables, reseal the packaging bag and cover the glue - melting tank to prevent impurities from mixing in and blocking the hose and spray gun.

4.The use place should be well - ventilated and kept away from open flames.

5.Since the glue - melting tank and the glue - spraying system are at high temperatures, safety protective equipment must be worn during operation to prevent burns.

6.Avoid contact between the melted glue and parts such as eyes and skin.

7.If the melted glue comes into contact with the skin, immediately immerse the affected skin in cold water and rinse for at least 10 minutes. Seek medical treatment in a timely manner after cooling.

Why Choose UNISN

•Fast Melting Speed: It can transform from a solid state to a liquid state in a relatively short time, allowing it to be used quickly and improving production efficiency.
•Good Fluidity: It can be quickly and evenly coated on the surface of the adherend and fit well, ensuring the integrity of the bond.
•Fast Curing Speed: It enables the adherends to be fixed quickly, greatly shortening the production cycle.
•High Bonding Strength: It has good bonding performance with a variety of materials, ensuring that the bonded objects will not easily fall off or separate.
•Good Anti - brittleness Property: Under the long - term influence of external forces during the use of the mattress, it can maintain good flexibility and bonding strength, and is not prone to brittle fracture or glue - off.
•Good High - Temperature Resistance: In a certain high - temperature environment, it can still maintain good bonding strength and stability, making it suitable for high - temperature environments.
•Environmentally Friendly and Harmless: It is made from environmentally friendly raw materials, causing no pollution to human health and the environment. It can be widely used in fields with high environmental requirements.

•Low Odor: It can avoid the emission of pungent or unpleasant odors, which is user - friendly for product users.
