Thermal insulation rock wool board is widely used in our life and some industries. How to choose this material when purchasing? This is a problem that we need to understand. Only by making good choices can we bring more and better help. Jinan rock wool board manufacturer explains for you.
When selecting rock wool insulation materials, the first thing to choose is the degree of insulation, that is, whether there are many environmental constraints. If there are many constraints, the natural use effect will be affected. What's more, we should pay attention to the sound absorption effect when choosing, not only to achieve heat preservation, but also to achieve the purpose of sound absorption.
When choosing, we should pay attention to the service life. If the service life is too short, it will be replaced naturally after a period of use. It is not only troublesome, but also a big expense in terms of capital consumption. Therefore, we should choose well when choosing.
The facilities and air ducts required for heating shall be free of leakage, dry and free of grease. Under these conditions, they will not rust and take root, which is conducive to corrosion. The coating can be appropriate.
In order to reduce the heat loss of connectors, panels and felt for various purposes, they must be very close to the abutment. When their respective multi layer insulation joints are staggered, they should avoid hot bridges and cold bridges.
Rock wool insulation is applicable to outdoor use or metal or plastic sheaths and other parts prone to mechanical wear. Attention shall be paid to the sealing of joints and seams. If necessary, sealant can be added. The sealing layer of overlapping parts shall not be less than 100mm. The cold vapor barrier must be protected in cold weather. At low temperature, the rock wool board is insulated without resin, and the damp proof layer is fireproof.
For large diameter equipment flat wall or rock wool insulation board products, insulation nails above 200 ℃ shall be added, and the outer sheaths (spacing 400mm) shall be closely aligned. When the insulation object is placed vertically, it has a considerable height. The insulation layer must be equipped with locating pins or bearing rings, with a spacing of no more than 3 meters, to prevent the insulation material from sliding downward when vibrating.
The thermal insulation performance of rock wool thermal insulation material has always been very good, especially the rock wool thermal insulation board, its thermal insulation performance is much better than the additional thermal insulation board at room temperature. In addition, the rock wool insulation effect is quite good, of course, we should pay more attention to the relevant issues, so we can ask him to use more.
