The advantages and disadvtages of rock wool insulation board 2024-07-22 11:47:46 internet

The rock wool thermal insulation board is based on Xuanwu Rock and other natural ore as the main raw materials. After melting, the international advanced four -roller centrifugal cotton processes are used to pull the high -temperature solution of the basalt of the basalt into non -continuous fibers of 4-7 μm. ThenAdd a certain amount of adhesive, dust oil, and water hate in rock wool fibers. After settlement, curing, cutting and other processes, different density products are made according to different uses.Rock wool insulation board products are suitable for industrial equipment, buildings, ships, and sound insulation.
The advantages and disadvantages of rock wool insulation board
On the whole, the rock wool thermal insulation board has light quality, the coefficient of heat conduction is very small, good elastic, not easy to burn, not easy to rot, chemical stability is strong, and it also has the best sound insulation performance.The rock wool board cannot replace the slope, and you need to do it yourself.Therefore, it will be very troublesome and delay the construction time.The water absorption of the rock wool insulation plate is very good, so excess water will easily accumulate in the inside of the rock wool plate. After a long period of accumulation, it will increase the weight of the insulation layer, which will cause the insulation layer to fall off.It is known that its repairs are also very high.
Rock wool insulation board is heavy
In theory, the country currently has standardized guiding documents, and the items 65 are clearly indicated that the rock wool boards on the outer wall generally need to be above 150kg, the thickness is above 40mm+, and the nominal weight is 140-200kg/m3.about.However, the specific standards can be reasonably adjusted according to different regions and different temperature differences.For example, the specifications of the south are about 120-160kg and 30-60mm thick, but in the north, due to the temperature difference between the day and night, the rock wool thermal insulation board will increase thickening, about 130-180kg, 50-80mm.
Rock wool insulation board specification
There are many types of rock wool composite boards., Steel mesh rock wool board, cement composite rock wool board, different types of rock wool composite plate specifications also have a large difference.The specifications of rock wool composite boards are mainly stipulated in the aspects of thickness and length and width.60*30cm, etc.
Rock wool insulation board construction process
The grass-roots walls should comply with the requirements of the "Code for the Construction Quality Acceptance of the Concrete Structure Engineering Project" (GB50204--002) "Specification for the Construction Quality Acceptance of Masonry Engineering" (GB50203-2002) and the corresponding grass-roots wall quality acceptance specifications.Relevant departments do a good job of confirmation of structural acceptance.If the deviation of the grass -roots wall is too large, the mortar should be placed flat.
Rock wool insulation board price
The general exterior wall thermal insulation in the Beijing -Tianjin area requires Rongzhong Rock Board for 140kg, and rock wool is more than 100kg, with a thickness of 70mm.According to this standard, the rock wool board should be 60 to 65 yuan/square meter, and the rock wool is 47 to 50 yuan.This price is the highest level of products in China.
