When it comes to rock wool boards on the outside, everyone may feel very strange. The outer wall rock wool board is suitable for the petrochemical industry, and is used for heat insulation and insulation of electric power, petroleum, and chemical industry equipment to absorb sound and reduce noise; it can also be used in the construction industry. It can construct partition walls, roofs, curtain walls, and enclosures to insulate heat and absorb sound. noise. Since there are so many applications for outer wall rockwool panels, how many people know about the outer wall rockwool panels? We all know how much the specifications of outer wall rockwool panels are? Here's a brief introduction to the construction process of rockwool panels for external walls. , to tell you what are the specific construction steps.
What is an external rock wool board
The outer wall rock wool board uses basalt as raw material and is melted at a high temperature, and adopts a four-roller centrifugal cotton making process. The basalt wool high-temperature melting body can be thrown into a 4-7 μm non-continuous fiber, and a certain amount of binder is added. , dust oil, curing, cutting and other processes, and then made according to different uses of different density products. Rock wool is suitable for construction, petroleum, metallurgy, national defense and other industries. It is the heat insulation and sound insulation of industrial equipment such as pipeline storage tanks, flue pipes, heat exchangers, vehicles and ships.
Exterior rock wool board features
1. High pressure resistance, tensile strength and durability ensure the stability and reliability of the product.
2, rock wool does not burn, does not release toxic fumes, fire cut off the effective cut off the flame, excellent fire performance.
3, superior insulation, thermal insulation performance, reduce building heating and air conditioning energy consumption, energy conservation and emission reduction.
4, no corrosion of metal materials, various components.
5, high-performance sound absorption and noise reduction, elastic damping physical properties.
6, non-hygroscopic, anti-aging, stable performance.
7, light weight, can be cut to saw, easy to process.
External wall rock wool board system structure:
Mainly by: adhesive layer, insulation layer, surface layer, finish layer and accessories.
The adhesive layer is between the bottom layer and the top layer, and the top and bottom layers are bonded together with a cementitious material. The filler is derived from inorganic substances.
Insulation layer, to avoid the loss of heat to the environment, the appearance of the laying of the insulation material layer, the filler is rock wool, a certain amount of organic matter, moisture, as well as adhesives.
The finish layer uses a lightweight functional coating or a breathable water-based exterior paint, which increases the aesthetics.
Accessories, the use of various types of paint, on the one hand to increase the surface color, to a certain extent, play a role in flame retardant, thermal insulation.
External wall rock wool board construction process
I. Preparation
Before the construction, a series of preparations, such as preparing materials and construction equipment, and checking to ensure that the appearance is intact. Transport it to a suitable location and store it neatly for use in construction.
Second, determine the bomb line, the baseline
The highest point of the line, every three nodes to do the node, so that the wall is vertical, horizontal and vertical lines pop up in the wall, easy to control the flatness of the rock wool board.
Third, adhesive mortar
After the line is stretched, prepare the mortar for reconciliation. Use a mortar mixer and stir for more than 5 minutes. Mix as much as possible to ensure a moderate consistency. During the mixing process, cement, quick-setting agent, filler, and coloring material shall not be mixed.
Fourth, paste operation
The exposed part of the rockwool board is subjected to steel wire mesh tumbling treatment. The adhesive is applied on the surface of the rock wool board. The bonding area is controlled at about 50% to ensure firm bonding. Note that the whole piece of rock wool board should not be used for splicing. .
Fifth, install the anchor
After 24 hours of sticking, install the anchor. In order to achieve a better thermal insulation effect, apply a crack-resistant mortar on the anchor to fully cover the anchor.
Sixth, repair details
After pasting, it should be polished properly. The deviation of the flatness at the seam is 1.5mm, and it is smoothed with sandpaper. After the scaffold was removed, the holes were leveled with cement mortar. The wet brush leveled uneven areas and finished the final finishing job.
Editor's summary: The outer wall rock wool board is made of selected basalt and diabase as the main raw materials, with non-combustible, non-toxic, light weight, low thermal conductivity, good sound absorption performance, good insulation, chemical stability, long service life, etc. Features are recognized as ideal insulation materials at home and abroad. Everyone in the home renovation may wish to consider using an external rock wool board.
