According to the thermal conductivity coefficient of XPS extruded thermal insulation board is 0.027 and the required temperature of storage is -20℃, the following methods are adopted as quick-freezing storage:

First, the warehouse wall and the roof before doing insulation to do a layer of air insulation. Before the use of plastic sheets in the construction, now most of the normal cold storage using cyanogen coagulation do gas insulation layer;

2. Ground construction method: the ground adopts two layers of 8cm extruded plastic plates to be spread and pasted according to the staggered joints

First make waterproof layer (plastic paper) and then lay XPS extruded insulation board. Leave seam on the side of each board, about 2 marks. Then adopt polyurethane adhesive sealing.

Construction method of wall panel and top panel

Two layers of 8cm extruded sheet were applied according to the staggered joints, and the surface was sprayed with 3 amp polyurethane

First, paste a layer of 8cm extruder plate directly on the wall, and then fix it with 10cm plastic expansion screws. Press 3-4 expansion screws per square, and then glue the side of each extruder plate with polyurethane pouring joints. The second layer 8 cm

The extruded sheet is glued with polyurethane adhesive. The outer surface is sprayed with 3 struts polyurethane as the sealing layer.

According to the thermal conductivity coefficient of XPS extruded thermal insulation board is 0.027 and the required temperature of high temperature storage is 0℃, the following methods are adopted for construction:

First, the warehouse wall and roof before the insulation to make a layer of insulation layer, using cyan condensation as the insulation layer, to prevent the water vapor into, the water vapor into the cold storage directly leads to the insulation effect of the failure;

Two, ground construction method

The ground is covered with two layers of 5cm extruded plastic plates in accordance with the staggered joints

Make waterproof layer (plastic paper) first, lay a layer of plastic cloth, the wall thickness is 0.018, and then lay XPS extruded insulation board, each board left side seam, and then use polyurethane bonding sealing, the requirements of polyurethane adding material should not be higher than the plane of XPS extruded board.

Construction method of wall panel

The wall panel adopts two layers of 5cm extruded panels to be spread and pasted according to the staggered joints

First, paste a layer of 5cm extruded sheet onto the wall directly, and then fix it with 10cm plastic expansion nails. Press 3-4 expansion nails per square, and then glue the side of each extruded sheet with polyurethane pouring joints. The second layer of 5cm extruded sheet is pasted with polyurethane adhesive.

Construction method of top surface

For roofing: a layer of 8 stand extrusion panels is first hoisted onto the working steel beam and then sprayed with 3 stand polyurethane to seal the inside.
