1. Site selection skills
The location of the thermal insulation house of the breeding farm should be a place with a leeward wind and sunny, high terrain and dry soil.
2. Alternative insulation materials for the insulation room of the farm
Extruded polystyrene foam (extruded board), molded polystyrene foam (ordinary foam board), sprayed rigid foam polyurethane, rigid foam polyurethane insulation board (products), foam glass, foam concrete (foam mortar) ), chemically foamed cement board, lightweight aggregate insulation concrete (ceramsite concrete, etc.), inorganic insulation mortar (vitrified microbead insulation mortar), polystyrene particle insulation mortar, mineral wool (rock wool), phenolic resin board, expansion Perlite insulation mortar, inorganic active wall insulation materials, etc.
Three, mature insulation materials
Insulation materials for farms are of course foam, glass wool, and insulation ash. These materials have better performance in the insulation series. They must be sealed. The better the seal, the more stable the temperature control. These materials have been used maturely, and the effect is Not bad.
Using rock wool board, rock wool board has good thermal insulation effect and long service life, mainly because it is more economical.
Polyurethane construction case of thermal insulation room of breeding farm
Fourth, the characteristics of polyurethane insulation materials
After the civil construction of the farm is completed, spray polyurethane insulation material.
Polyurethane is foamed on-site and sprayed by a polyurethane high-pressure sprayer. It is easy to operate and can be used in any complex roof construction. Usually the construction is operated by 3-4 people. The spray can be more than 20 cubic meters per day. Calculated by millimeters, it can spray more than 700 square meters per day.
Polyurethane rigid foam is a dense microcellular foam with a closed cell ratio of more than 92%. It has a smooth self-skinning and is an excellent impermeable material. The
