Insulation materials in Guangxi Dragon insulation material PU rigid polyurethane foam construction methods 
 A construction site environment requirements: 
 ① base surface should be smooth, dry (moisture content <8%), no dust, no oil; 
 ② Temperature should not be less than 5 C; relative humidity should be less than 80%; wind should be less than 3. 
 2, in proportion to the provided A mixture of 8 material, mixing should be uniform, the thermal reaction should be fully and check the transmission pipeline leaks; 
 3, with a special spray equipment, spraying carried out by specialized operators: 
 ① The spray should be continuous, evenly spray, spray the biggest ripple is not greater than 5 mm; 
 The ② spray gun with the base surface, a distance of 400-800mm, the pressure of 8.0-10. OMPa spray time control in flat 3-5S, facade 1-3S; 
 ③ According to the thickness of a work surface can be divided into several times spraying completed, the date of the date of construction surfaces must be spraying Bi shaped parts directly spray; 
 Within 20 minutes after the ④ spraying is complete, is strictly prohibited Exalted walk or perform other operations; 
 The ⑤ thickness and surface quality inspection and approval, you can spray anti-UV coating protective layer or paint decorative layer.
