Explanation of the entire process operation method for insulation construction of color steel tank body

The process flow and characteristics of tank pipeline insulation engineering: 1. The thickness layer of the tank insulation engineering layer uses 50-150mm large swing hammer process insulation materials such as rock wool, glass wool, aluminum silicate, composite silicate, etc., with special requirements for staggered fixing in two layers. The outer protective layer is made of galvanized iron sheet, aluminum sheet, and color steel plate with a thickness of 0.3-0.6mm. It is formed by insulation concave convex groove edge pressing machine and rolled into a cylinder by anti slip rolling machine for overlapping in the direction of water flow, with appropriate width, smooth interface, and uniform wrapping.

Construction plan: 1) When reserving a 300mm fireproof isolation zone, a 50mm wide and 300mm high treasure phenolic insulation board can be fully coated with bonding mortar and pasted at the fireproof isolation zone to support the upper part of the phenolic insulation board. 2) The construction of the insulation layer with thermal insulation mortar should be carried out at least 2-3 times, with each time using 10-20mm of thermal insulation slurry. The construction thickness should be controlled at around 10mm, and attention should be paid to compaction. The thickness of the next construction should be controlled at around 10mm, and the interval between each two construction should be at least 24 hours. When the construction temperature is low, the interval time can be extended. 3) The construction of insulation mortar should be carried out from top to bottom. 4) During the construction of the insulation layer of the machine's thermal insulation mortar, the thickness of the ash cake reinforcement should be reached, and a large bar should be used to smooth it out, so that the flatness of the wall and door and window openings meets the requirements. Attention should be paid to compacting the insulation slurry when applying it. 5) The prepared insulation slurry should be used up within 4 hours. The insulation slurry scraped off by the large bar must be mixed and reused within 4 hours. It is strictly prohibited to use outdated insulation slurry. 6) After the insulation layer is cured and dried (the surface cannot be touched by hand, about 2-3 days), the next construction process can be carried out. If the ambient temperature is low, the curing time should be extended.

Explanation of the entire process operation method for insulation construction of color steel tank body

The purpose of tank insulation is generally to protect the tank equipment from the influence of external high or low temperature environments, and to prevent the high temperature of the equipment from dissipating and affecting other equipment. Therefore, tank insulation is divided into two categories based on these purposes:
1. High temperature insulation: This type of insulation project generally uses fiber insulation materials such as rock wool, glass wool, composite silicate, etc. Considering the high temperature environment, the insulation material should have high temperature resistance characteristics.
2. Low temperature insulation: This type of insulation project uses closed cell insulation materials such as polyurethane, which not only have good insulation effects, but also absorb water.
The inner layer is made of different materials, and the outer layer material should play a protective role, such as iron sheet, aluminum sheet, fiberglass, etc.
Construction method for tank insulation: The thickness layer of the tank insulation engineering layer uses 50-150mm large swing hammer process insulation materials such as rock wool, glass wool, aluminum silicate, composite silicate, etc. Special requirements include fixing them in two layers with staggered joints. The outer protective layer is made of galvanized iron sheet, aluminum sheet, and color steel plate with a thickness of 0.3-0.6mm. It is formed by insulation concave convex groove edge pressing machine and rolled into a cylinder by anti slip rolling machine for overlapping in the direction of water flow, with appropriate width, smooth interface, and uniform wrapping.
Characteristics of tank insulation construction: It has the advantages of good insulation effect, low engineering cost, short construction period, beautiful appearance, waterproof, fireproof, anti-corrosion, and a service life of up to 30-50 years.
