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
With the development of technology and society. Polyurethane spraying machines are also constantly developing and producing higher quality products. From manual foaming to low-pressure spraying machines to the current high-pressure spraying machines, they are also constantly updated and upgraded, co
Polyurea spray equipment is usually used in construction, mainly because polyurea has a strong anti-corrosion effect. Has a certain adhesion and strength. In order to improve the adhesion of the coating, it is necessary to strictly control the substrate used and improve it if necessary, so the polyu
The cold fog machine was once called the normal temperature fog machine, which is relatively speaking with the hot fog machine. It uses high-pressure air generated by an air compressor to form a high-speed rotating airflow through a pneumatic atomizing nozzle. The liquid medicine is formed into tiny
Polyurethane is a heat-insulating and waterproof coating. In buildings, its heat insulation and waterproof functions are widely used. Polyurethane spraying machine is a high-pressure polyurethane spraying equipment, because the material of the high-pressure spraying equipment collides and rotates vi
he polyurea spraying machine includes the main engine, spray gun, feed pump, feed pipe, A component, R component, heating hose and many other parts, which must be connected reasonably to ensure the smooth completion of the spraying operation.The two lifting pumps are respectively inserted into the i
Cold storage insulation we usually use polyurethane sandwich double-sided color steel cold storage insulation board or directly spray polyurethane facade on the wall for insulation. In the southeast of my country, polyurethane sandwich double-sided color steel cold storage insulation boards are most
(1) It does not contain a catalyst, and the curing speed is very fast. It can be sprayed on any kind of curved, inclined and vertical outermost layer without sagging, and it solidifies within 5 seconds. The glue can reach walking strength within 1 minute; (2) It is not very sensitive to humidity a
In recent years, polyurethane resins have made their composites stand out due to their good toughness, fast curing speed, and no styrene smoke. With people's mastery of polyurethane molding technology and progress in controlling its reactivity to extend its service life, polyurethane has long entere
1. What is polyurethane spraying?Polyurethane spraying technology is based on isocyanate and polyether as the main raw materials. Under the action of various additives such as blowing agent, catalyst, flame retardant, etc., through the use of special network equipment and mixing, the high-pressure s
The electric super-capacity sprayer is popular with more and more vegetable farmers because of its convenient use and high work efficiency. It has become the main tool for pest control in the greenhouse. However, electric sprayers are relatively "precious". Once they are improperly operated and main
