Comparison of thermal insulation structure of grain depot

Hits：1498 Time：2017-3-29
　　In view of the special requirements of heat preservation and sealing of grain depot, several types of steel structure are compared in the following aspects:
鋼結(jié)構(gòu)
There are three types of steel roof in the form of: first, the double plate sandwiched insulation cotton insulation, and the second, the double plate folder foam form insulation, three, arch roof indoor spray polyurethane insulation. The following state steel structure for each one of the analysis:
A, double plate clamp insulation form: steel, steel purlin and other primary and secondary structure of the form of every three years to do a preservative treatment, to ensure the service life; cotton insulation damp shrinkage and thermal insulation effect; integral sealing performance; thermal insulation service life of 10 years.
Two, double plate clamp foam form: steel, steel purlin and other primary and secondary structure of the form of every three years to do a preservative treatment, to ensure the service life; polyethylene foam insulation performance stability, thermal insulation effect is better than cotton insulation, but the foam density is not dense, is not ideal.
Because of the overlap between the foam boards, the overall sealing performance is general. Insulation life of 30 years.
Three, the arch roof indoor spraying polyurethane insulation: choose the structure form of the material is made of high strength galvanized steel plates produced by Baosteel Shanghai color, color plate itself has good anticorrosion performance; the roof panel is connected between the mechanical lock, with good waterproof and sealing performance; indoor spraying
Coated with polyurethane insulation, polyurethane is a waterproof, thermal insulation in one of the new materials, a construction, good integrity, good sealing, high efficiency spraying after construction work surface to form a layer of seamless continuous shell, which is currently the best insulation form overall service;
Life for 30 years.
