National standard construction of iron sheet thermal insulation in boiler room

Boiler room iron sheet insulation national standard construction

Construction method of rubber and plastic insulation board:

1. Shake the container before use to make the glue even. For the actual installation, use a small can of glue to prevent it from evaporating too quickly. If necessary, pour the larger jar into the smaller jar and use without prior sealing.

2. Using a short and stiff brush, apply a thin and even layer of glue to both ends of the material surface.

3. The natural drying time of special glue is 3-10 minutes, andthe duration depends on the adhesive quality, the weather temperature and humidity should generally follow: the higher the ambient temperature, the higher the relative humidity and the lower the medium temperature; the larger the diameter, the longer the material is exposed.

4. Wait for the glue to dry naturally during use. The correct way to measure the dryness is to touch the glue with your fingers. If the surface of the material does not stick to the fingers and the surface of the material is not sticky, it can be bonded. Just align the two surfaces of the adhesive interface and hold it firmly for a while.

5. Usually every kilogram of special adhesive for rubber and plastic can be used on two squaresante meter adhesive surface.

6. When connecting two materials under pressure, there is no need to wait for the glue to dry, use the wet bonding method, first place the material at the installation position, apply glue to the interface of the material, then adjust the position of the two materials and soon it will be firmly glued together according to the position of your design.

Boiler room iron sheet insulationThe working method of the whole process of tank insulation construction

The technical process and characteristics of the tank body pipe insulation project: 1. The thickness layer of the tank body insulation project uses a large pendulum with a thickness ofn 50-150mm. Hammer craft rock wool, glass wool, aluminum silicate, composite silicate and other thermal insulation materials should be specially fixed in two layers with staggered joints. The outer shell is made of galvanized iron sheet, aluminum sheet and colored steel sheet with a thickness of 0.3-0.6mm by insulation. a tube for overlap along the direction of the water flow, with suitable width, flat interface and even wrapping.

Building plan:

1) When booking 300 mm fire resistance, a width of 50 mm can be used. The 300mm high phenolic insulation board is covered with adhesive mortar and pasted on the fire insulation belt to support the upper part of the phenolic insulation board

2) The construction of the insulation mortar insulation layer is divided at least 2-3 times, and the insulation slurry applied each time is 10- 20mm,the construction thickness should be checked at about 10mm, pay attention to compaction, the thickness of the last construction should be checked at about 10mm, and the interval between each two constructions should be more than 24 hours. When the construction temperature is low, the interval can 3) Insulation The mortar construction should be from top to bottom

4) The thickness of the ash cake punching ribs should be achieved during the construction of the thermal insulation layer of the last machine insulation mortar, and it should be rubbed flat with a large bar to ensure the flatness of make the wall, door and window meet the requirements. Take care when applying the thermal insulation slurry. It needs to be compacted and compacted.

5) The prepared thermal insulation slurry should be used up within 4 hours, and the heat insulation slurry scraped off by the large rod should be used again within 4 hours after stirring. It is strictly prohibited outdated heat isoto use lattice slurry.

6) After the insulation layer is cured and dried (the surface cannot be pressed by hand, about 2-3 days), the following process can be carried out. If the ambient temperature is low, the curing time may need to be extended.

Whole process method of tank insulation construction

Fire room iron sheet insulation The purpose of tank insulation is generally to protect the tank equipment from the influence of external environment with high or low temperature, and the high temperature of the equipment does not affect other equipment, so according to these purposes, the tank insulation is divided into two categories: 1. High temperature insulation: This insulation project generally uses rock wool, glass wool, composite silicate, etc. Fibrous thermal insulation materials, rebearing in mind the high temperature environment, so the thermal insulation materials must be able to withstand high temperature.
2. Low Temperature Insulation: This type of insulation project uses closed cell insulation materials such as polyurethane, which not only has good insulation effect, but also absorbs water.
The inner layer is made of different materials, and the material of the outer layer should play a protective role, such as iron plate, aluminum plate, glass fiber reinforced plastic, etc.
Tank body insulation construction method: the tank body insulation layer thickness layer uses 50-150mm large-scale pendulum technology, rock wool, glass wool, aluminum silicate, composite silicate and other insulation materials, and special requirements are divided into two layers Seam fixed. The outer shell is made of galvanized iron sheet, aluminum sheet and colored steel sheet with a thickness of 0.3-0.6mm.It is wrapped by concave-convex groove type edge press machine for heat preservation, and rolled into a tube by non-slip rounding machine.It is suitable for water flow direction.Wrap flat and evenly.
Construction features of the tank thermal insulation: it has the advantages of good thermal insulation effect, low technical cost, short construction period, beautiful appearance, waterproof, fireproof, anti-corrosion, etc., and the service life is so long as 30-50 years old.
