Why do thermal insulation rock wool boards need to be sprayed with hot melt adhesive?

Suzhou Oushida has done a lot in recent years on thermal insulation materials - thermal insulation rock wool boards. Today, let's take a brief look at the spraying of thermal insulation rock wool boards and their advantages:

What is thermal insulation rock wool board?

Simply put, the high-temperature melt of basalt wool rock is pulled into fibers, and then cured and cut into products of different densities after adding adhesives. It is often used for insulation and sound insulation of industrial equipment, buildings, and ships.

Why is it necessary to spray glue?

Not all rock wool boards need to be sprayed with glue. Some thermal insulation rock wool boards/rock wool felts need to be covered with a layer of aluminum foil on the rock wool, and then hot melt glue needs to be sprayed.

Why cover with a layer of aluminum foil?

There are many functions:

1. Enhance thermal insulation effect

2. Moisture-proof and moisture-proof

3. Improve durability

4. Beautiful decoration.

The most important thing is better thermal insulation.

Where is it used?

It can be used for thermal insulation of heating and cooling equipment pipes, sound insulation of buildings, protective wrapping of petrochemical pipes, water vapor barrier of pipes, anti-light radiation, etc. Fireproof aluminum foil can also be used for various curtain walls and floor slabs, pipes, and smoke fire separation.

The application of hot melt adhesive in thermal insulation rock wool board is mainly due to its unique advantages, including flame retardancy, safety, fast curing, water and moisture resistance, and cost-effectiveness.

Flame retardancy and safety: Hot melt adhesive has the characteristics of flame retardancy and explosion-proof, and is harmless to the human body, which makes it an ideal choice for bonding thermal insulation materials because it not only ensures construction safety but also protects the health of users.

Fast curing: Hot melt adhesive can cure quickly after spraying, without waiting for a long time to dry, which greatly improves construction efficiency and also ensures the adhesion and flexibility of the product.

Water and moisture resistance: Hot melt adhesive has a long-lasting effect and can adapt to various environments, especially water and moisture resistance, which is particularly important for insulation materials because it ensures that the material still maintains excellent insulation performance in a humid environment.

Cost-effectiveness: The price of hot melt adhesive is relatively low, and its effect is long-lasting and can adapt to various environments, which makes it cost-effective while providing excellent insulation effect. In summary, hot melt adhesive is widely used in the bonding of insulation materials due to its unique physical and chemical properties, as well as its advantages in construction and use, to ensure the safety, efficiency and durability of insulation materials.
