Fireproof rock wool board is a kind of material commonly used for building external walls. The rock wool board is mainly made of water-repellent rock wool board produced by the pendulum method and is made of thermal insulation material. The rock wool composite board is made of natural rock such as basalt and hui. Changyan, dolomite, iron ore, aluminum vanadium and other major raw materials, it is a thermal insulation material. This kind of material is mainly suitable for thermal insulation of electric power and chemical industry equipment, insulation insulation and noise reduction of building external walls. Then let's take a look at how the fireproof rock wool board construction process is done.
Fireproof rock wool board
The rock wool board is mainly made of water-repellent type rock wool board produced by the pendulum method, and the rock wool compound board is made of natural rock such as basalt, gabbro, dolomite, iron ore, aluminum vanadium, etc. As the main raw material, an inorganic fiber made by adding an appropriate amount of binder and hydrophobic agent through high temperature melting and fibration is implemented in GB/T25975-2010 "rock wool product for external thermal insulation of building exterior wall"; slag Rock wool cotton is made of industrial slag such as blast furnace slag, phosphate slag, fly ash as the main raw material, after remelting fiber made of inorganic fiber. The introduction of the main Class A fireproof exterior wall insulation system on the market (the following text is selected from the Chinese Building Standard Design and Research Institute, "External Exterior Insulation Building Construction" standard number 10J121) and its implementation standard is GB/T11835-2007 "heat insulation with rock wool Slag wool and its products."
Rock wool composite panels and slag rock wool panels are collectively referred to as mineral wool. The slag wool was widely used in metallurgy, machinery, building materials, petroleum, and chemical industries in the 1970s. Rock wool was used for external wall insulation in developed countries such as the European Union. It has a history of nearly 30 years. In China, because of its high production cost and cost, the economic cost is greater than that of organic insulation materials, making it not applicable to a large extent.
National standard
Due to the low combustion performance of organic insulation materials, fires frequently occur, resulting in heavy casualties and economic losses. The National Fire Protection Bureau and the Ministry of Construction of the Ministry of Public Security attach great importance to it and require external insulation of the building to use combustion performance of class A or A1. Insulation materials, basalt rock wool composite panels that are one of the Class A non-combustible materials, have been widely promoted in China with their superior technical performance, and the performance of slag rock wool panels cannot meet the requirements of exterior wall insulation materials and are prohibited from use. Wall insulation.

Fireproof rock wool board construction process
Fireproof rock wool board construction process: the following points in the process
1. The main key of the outer wall insulation of the fireproof rock wool board is that the composition of the outer wall insulation of the rock wool board is mainly composed of three layers: a wall structure layer, an insulation layer, and a decorative layer. The insulation layer and the structural layer are the connection methods used. After the construction of the keel is completed, the fireproof rock insulation layer is applied in the keel sandwich.
2. The connection mode between the insulation layer and the structural layer is fixed by the expansion bolt scheme. Six expansion bolts are used for each rock wool plate. The thickness of the rock wool plate is generally about 50-100, and the plaster layer is about 15 When constructing, in order to ensure that the expansion bolts are more than 25 when they are anchored into the structural layer, we generally mark the drill bit. To ensure that the rock wool board thickness does not appear negative.
3, rock wool board installation
(1) Typesetting requirements for fireproof rock wool board. In strict accordance with the standards, the entire sheet is to be laid horizontally in a horizontal direction from the bottom to the top in the direction of a half length of the board, starting from the corners of the wall and vertically staggered to secure the sheet. Make sure the corners are straight and vertical. In the Yin and Yang angles, rock wool boards are interlocked. Note that in the four corners of the door and window openings, it is not possible to splice the rock wool board. The whole block of rock wool board must be cut and formed. The incision should be perpendicular to the layout. In the corners of the wall, use the same insulation board to stick and fix it.
(2) Fireproof rock wool boards must be laid out before use. To calculate the size of the material to be cut, the diameter error of the trimmed edge should be controlled within 5mm, and the error of the stitched seam should be controlled within 2mm.
(3) The laying of rock wool boards should be connected from top to bottom. The rock wool boards should be laid in order. When encountering the door and window openings, it is necessary to meet the requirements of changing the atlas.
The above points are the summary of this site for everyone to sum up the fire rock wool board construction process related information, I believe we will have a certain understanding after reading, so that everyone will know a lot, if we still have those who want You can check it out on our website.
