XPS Key points of extrusion board construction
one Snap the control line according to the building facade design and external wall thermal insulation technical requirements doors and windows Horizontal and vertical control lines, expansion line joints, decorative line joints, etc.
two , hang the datum line at the big corner (external corner, internal corner) and other The vertical datum steel line shall be hung where necessary, and the horizontal line shall be hung at the appropriate position of each floor to control the perpendicularity and flatness of the extruded plate.
three , configuring mortar Press the height building adhesive and water 4:1 Proportional preparation: Evenly mix with electric mixer, and the dosage of one preparation should be used up within one hour. The prepared materials shall be protected from sun and wind. Do not add water again after the operation time.
four , paste the flipped bag / Extruded board (peeling) polymerization benzene The standard size of plate is generally 1200*600mm The operator shall use a carpenter's knife saw or electric wire cutter to cut when changing the size. First roughen the extrusion plate, and then evenly coat the interface agent on both sides of the extrusion plate; Six scrapers in the middle with a diameter of about 100mm The bonding point shall be evenly distributed step by step, and the bonding area shall not be less than 40% 。 The plates shall be arranged in horizontal order, and pasted with staggered joints up and down. The internal and external corners shall be treated with staggered joints.
five The adhesive plate shall be used gently with special tools, and the extruded plate shall be extruded evenly at any time 2m Check the flatness and perpendicularity with the guiding rule and the towing plate. When sticking the board, pay attention to removing the adhesive overflowing from the board edge, so that there is no "bump ash" between the boards. The height difference of butt joint is not greater than 1.5mm Otherwise, sand paper or special grinding machine shall be used to polish the surface.
six , apply anti crack mortar on the bottom layer of extruded board, thickness 2-3mm At the same time, press the overturned mesh cloth into the mortar.
seven Paste the grid cloth tightly and thickly on the anti crack mortar of the bottom layer, press the grid cloth into the surface of the mortar from the middle to the periphery with a trowel, and keep it flat and compacted. No wrinkles are allowed on the grid cloth. The mesh cloth shall not be pressed too deep, and the surface must be exposed outside the base mortar.
eight The anti crack mortar of the plastering layer shall be plastered with a layer of anti crack mortar overlay before the anti crack mortar of the bottom layer is set 1-2mm It is better to cover the grid cloth and slightly see the grid cloth outline. The surface mortar shall not be continuously rubbed to avoid hollowing.
nine The coating construction can be carried out when the plastering base meets the coating construction requirements. The construction method is the same as that of ordinary wall coating.
ten , facing brick method When the design requires that the partial external facing is facing brick, select 30-35kg/m ³ Polystyrene board, bonding area not less than 50% 。
XPS The honeycomb closed cell structure of extruded board enables the board to have high thermal insulation, waterproof and moisture-proof, sound insulation and sound absorption effects. It is used for building external wall insulation, roof insulation, foundation waterproof and moisture-proof, cold storage construction, floor mats and other aspects.
XPS Extruded boards have different specifications, which are divided into XPS Plastic extruded board B1 Level and B2 Grade A and ordinary non flame retardant extruded board; According to the thickness of extruded plate two Cm to ten Every centimeter, 7cm ； According to the weight of the extruded plate twenty-six Kg to thirty-five kg .
Then the extruded plate B1 Grade xps extruded board and B2 What is the difference of level? Refer to GB8624-2012 Combustion Performance Analysis of Building Material Grade Products and GB/T30595-2014 Extruded polystyrene board（ XPS ）Thin plastered exterior wall insulation system materials Provisions of 。
GB8624-2012 The relevant provisions in the Analysis of Combustion Performance of Building Material Grade Products are as follows:
Combustion performance grade of building materials and products
Combustion performance grade | name |
A | Non combustible materials (products) |
B1 | Refractory materials (products) |
B2 | Combustible materials (products) |
B3 | Flammable materials (products) |
The combustion performance grades and grading criteria of flat building materials and products are shown in the table below, which meet A1 、 A2 Level is A Level, satisfied B Level C Level is B1 Level, satisfied D Level E Level is B2 Level. The wall insulation foam plastic shall meet the following requirements in addition to the provisions in the following table: B1 Grade oxygen index value OI ≥ 30% ； B2 Grade oxygen index value OI ≥ 26% 。
