Thermosetting composite polystyrene board Polystyrene insulation board is used as the insulation layer, the full name is polyethylene insulation foam board, alias insulation foam board or EPS board. It is made of expandable polyethylene beads with volatile liquid styrofoam, which is pre-heated and formed into a milky white solid with a fine omental sac structure after being pre-heated.

Wuzhou recommends how to construct the polystyrene insulation board wall insulation system software:

1. Rural grassroots removal.

Remove the residual ash layer on the concrete wall, the oil stain of the release agent and the hollow position of the putty wall, etc., and carry out the restoration. The sealing density of various holes in the wall. It is stipulated that the flatness error of the surface of the polystyrene insulation board should not exceed 4mm. When the error is exceeded, the highlighted wall will be polished and the concave position will be flattened.

2. Accurate measurement, setting-out and hanging of the wall. According to the facade design plan and building thermal insulation technical standards, the level of windows and doors, vertical control lines and retractable lines, decorative design stitching lines, etc. are ejected from the walls. Place vertical reference points on the large corners of the building's outer wall and where it must be, and hang straight lines on appropriate parts of each building to control the flatness and flatness of the polystyrene insulation board.

3. Paste the flip-pack alkali-resistant grid cloth. Wherever the exposed side of the polystyrene insulation board is pasted, it should be turned over with alkali-resistant mesh cloth. The 80mm width of the alkali-resistant grid cloth that is not less than 200mm wide is firmly adhered to the reference surface with a special type of plastering mortar. When the polystyrene insulation board is pasted in the middle and late stages, the remaining alkali-resistant grid cloth is turned over.

4. Paste polystyrene insulation board. The standard size of polystyrene insulation board for external wall insulation is 600Mm×900Mm and 600Mm×1200Mm. Non-standard sizes or some irregularities can be cut on the spot on the edge of a whole wall and use polystyrene insulation boards with a minimum specification exceeding 300mm. The joints of the polystyrene insulation board cannot be left at the four corners of the door dialog box.

Because the flatness of the surface of the rural grassroots wall is not good enough, it is advisable to use the point-and-frame bonding method. When the veneer is an architectural coating method, the total bonding area should not be less than 40%. Do not wipe the surface mortar on the side of the board. When arranging the boards, arrange them in the horizontal order, and paste them through the left and right seams, and make mistakes in the corners to solve the problem. To

Even when the board is glued, the surface mortar overflowing from the edge of the board is clear, so that there is no "head ash" between the board and the board. The splicing should be tight, and when the seam width exceeds 3mm, a relatively thin polystyrene sheet should be used to block it. The slope of the joint should not exceed 1.5 mm.

5. The rock wool board on the outer wall is fixed. When using mechanical equipment to fix the polystyrene insulation board on the outer wall of the rock wool board, the installation of the outer wall rock wool board should be carried out at least 24 hours after the plastering mortar is applied. Use an electric impact drill to make a hole in the surface of the polystyrene insulation board. The diameter depends on the diameter. The outer wall rock wool slab depends on the diameter, and the depth of the wall entry shall not be lower than the design plan. Screw in or knock out the anchor nails, the nail head and disc shall not exceed the surface.

6. Wipe the bottom layer of high-strength grout. After the polystyrene insulation board sticking and the outer wall rock wool board construction is completed and the work experience is accepted, the epoxy mortar batch putty will be carried out, and the bottom layer of high-strength grouting material will be applied on the polystyrene insulation board surface, and the alkali-resistant mesh cloth will be turned over Press into the cement mortar. The four corners of the door dialog box and the position of the outer corner line are commonly used to improve the alkali resistance grid cloth and then pressed into the cement mortar.

7. Pave the alkali-resistant grid cloth. Tighten the alkali-resistant grid cloth and stick it on the bottom layer of high-strength grouting material. Use a scraper to press the alkali-resistant grid cloth into the surface of the cement mortar from the center to the surrounding area. It must be leveled and compacted. Alkali-resistant grid cloth is prohibited. Folds. Alkali-resistant mesh cloth cannot be pressed too deep. In the case of lapped steel bars, be sure to consider the length of lapped steel bars of 100mm horizontally and 80mm vertically.

Before the bottom layer of cement mortar is solidified, apply a high-strength grouting elastic paint to cover only the alkali-resistant grid cloth and slightly see the alkali-resistant grid cloth contours. Do not continue to knead the cement mortar of the overall surface layer to prevent wall hollowing.
