Features and Advantages

The products have higher strength and better elasticity. The folded rock wol board with certain compression resistance has greater drawing strength, and it does not tend to peel off and has greatly improved durability.


Elastic mid-strength rock wool board: used for heat preservation, fireproofing and sound absorption for the building wall/roof, such as curtain wall, inner wall partition and elevator hoistway, etc.

High-strength rock wool board: used for various high/low temperature conditions, with good weight-bearing ability and compression-resistance, specially suitable for heat preservation and heat insulation for large ships, tanks, ovens,pipelines and other industrial facilities.

Compression-resistant rock wool board: used for roof heat preservation of airport lounge and large workshop as it could bear huge loads.

1. Introduction

Rock wool board

Rock wool is an artificial inorganic fiber made from melted basalt slag wool at high temperature.

It has the characteristics of light weight, small thermal conductivity, good sound absorption performance, non-combustible and good chemical stability.


2. Advantages

Primary advantages of rock wool panel

1)Fire protection: The panel material is non-combustible materials, which can fully meet the requirements of fire protection regulations. The combustion performance depends on how much of the flammable binder is present. Rockwool itself is an inorganic mineral fiber so that not flammable. The using life of the board can reach more than 35 years.

2)Sound insulation performance: Rockwool products have excellent sound insulation and sound absorption. The sound absorption mechanism is the product’s porous structure. When the sound waves pass, friction is generated due to the flow resistance, so that the sound energy is partially absorbs and impedes the transmission of sound waves.

3)Insulation: Rockwool has low thermal conductivity and good thermal insulation. The good thermal insulation performance is the basic characteristics of rock wool and its products. Under normal temperature conditions (about 250C), the thermal conductivity of rock wool is usually between 0.03 and 0.047W/(m·K).


3.Main functions

What is the purpose of the rock wool board?

Marine rock wool board for thermal insulation and fireproofing of ships.

Waterproof rock wool board for vehicles, mobile equipment, cold storage projects, air conditioning ducts.

The rock wool board for construction has excellent fireproof, thermal insulation and sound absorbing properties.


4. Where can rock wool board be used?

Rockwool composite panels are widely used in the ceilings and partitions of steel structure workshops, roofs of simple movable houses, walls, and air clean rooms.

The rock wool panel is suitable for temperature control process, energy conservation and personal protection of equipment and pipelines such as boilers, steam pipes, heat exchangers, reactors, ovens, furnaces, etc., and has good sound absorption, noise reduction and fire prevention.


5. Applications

In modern society, new material rock wool board have been widely used in construction, metallurgy, chemical, electric power, petroleum, agriculture, machinery, light industry, textile, military, transportation, warehousing and other industries. Various buildings, industrial furnaces, boilers, heat exchangers, distillation towers, storage tanks, cold storage flue, pipes, valves, fans, air conditioners, vehicles and ships, as well as the development of modern defense, aerospace, and atomic energy technologies are all this new type of multi-functional material for thermal insulation, sound absorption and noise reduction.


a)Building energy efficiency

b)Industrial insulation


d)Agricultural application

Cautions for use

1. Waterproofing is very important. Rock wool board can't be constructed in rainy days, and must be careful not to be wet by rain when storing. Otherwise, rock wool board may not achieve the expected effect.

2. If the rock wool board is used for cold preservation, we must add a moisture-proof layer into the rock wool board, but this moisture-proof layer must also be fire-proof. Otherwise, if there is a fire, our efforts will be wasted.

3. Then, the rock wool board cannot be scratched by sharp objects, the rock wool board should be well protected when the joint is made, otherwise it will be damaged. If the temperature exceeds 200 degrees Celsius, you should add the insulation nail. Of course must keep a certain distance and stick the foreigner; otherwise it will achieve half the effects.


8.Manufacturing process

ØThe rock wool fiber is controlled by speed track, and then pressed into rock wool board by the upper and lower crawler press method. The density of the rock wool board depends on the speed track and the drop of the oscillating weight. After shaking the hammer cotton, the rock wool is transported to a high temperature drying furnace by a crawler up and down pressing method, and dried to form rock wool board.

ØThe high-speed cutting saw in the oven longitudinally cut into a wide uniform long board. On this basis, the same length of rock wool board is controlled by a high-speed cutting saw. It is sent to the packaging equipment by conveyor belt. The rock wool veneers are overlapped by the self-extraction method to form fixed packing amount of rock wool board.

ØThen, the rock wool board is sent to the packaging platform through the conveyor belt, automatically transferred to the thermoplastic mold packaging process, the equipment automatically wraps the rock wool board with the special film of heat shrinkable. After this the rock wool board is tightly wrapped, and transport to the rock wool board storage room. On this basis, the whole process of rock wool board production is completed.
