2, PE class heat resistance is low, only applicable to the general and mid-range of the construction of the underground works and with a rigid waterproof layer of roofing waterproof layer, the roof should be used immediately as a protective layer.

3, when used alone, the thickness should not be less than 2mm, two or more of the fortification, the thickness of each layer should not be less than 1.5mm. Thickness 1.2mm and non film (N type) membrane used only as auxiliary waterproof.

Seven, construction technology

- process:

Primary treatment, coating substrate treatment agent, Western additional layer, large self adhered membrane paving, exhaust compaction (steel roller rolling) - lap construction to protect the isolation layer construction

- Basic cleaning:

The basic level should be conducive to the laying of the coil and paste, compaction and smooth, smooth surface, clean and dry, no dust oil, water content is not more than 9%.

Brushing or spraying the basic treatment agent: such as the basic level clean without dirt, can not use the basic treatment agent. Wooden iron can not base treatment level.

Detail node additional waterproof layer construction: the basic treatment agent after drying in a timely manner according to the relevant specifications or design requirements to do additional waterproof layer of the parts to be treated. To use the auxiliary burner of the coil is not easy to paste the details. General parts of the additional layer of the membrane should be glued to the basic level, the stress concentration parts supply in accordance with the norms of space shop.

Large self adhered membrane paving:

1. First coil alignment spread out in front of the base line, from one end of the coil (together with the isolation paper) uncovered, along the roll width midline fold, paper cutting knife will roll back the isolation paper gently gash, carefully torn a about

500mm, this paper will tear roll isolation alignment datum line paving location. Then uncover the half width coil re spread in place,; pull peeled off the release paper and forced right pull, slowly the half range membrane isolation paper all out, will be sticky membrane paving compaction. In accordance with the above method, the other half of a piece of adhesive sheet, pull the isolation paper at any time to pay attention to the integrity of the isolation paper, found tearing, breaking, should immediately stop pulling the shop, will tear off the remnants of the separation of the separation of the paper clean up, and then continue to work.

2 after the coil is pasted, press roller to roll from the middle part of the coiled material to both sides, and the air is discharged, so that the coil is firmly stuck on the base layer. Construction personnel should avoid contamination of the surface of the rolled sheet, so as not to affect the lap.

3 the width of the lap joint is not less than 100mm. Coil lap parts with a small hand press roll from the inside out of the rolling, discharge air, after the use of special sealing material sealing, sealing width of not less than 10mm.

4 coiled material should be coiled end cut together, into the reserved grooves, with special sealing material filling seal. Immediately the construction of steel nails with a nail seal, sealed with a special seal.

Construction of protective layer: waterproof layer construction is completed, the acceptance of qualified, with cement mortar or fine stone concrete as a protective layer.

Wet self-adhesive membrane construction technology

(applicable to the basement of the board, the side wall, the level of water content of more than 9% of the concrete base)

Process: clean the grass, humid, positioning, line - wipe cement sand slurry, nodes additional enhancement layer - the greater the noodle shop stick self-adhesive membrane - provided pulp, exhaust, overlapping edges paste - protection layer construction

1. Basic clean, moist: clean the dust and sundries on the surface of the base, the dry base surface should be pre sprinkler wetting, but can't have residual water.

2. Wipe cement slurry (sand), according to the Bureau has smooth conditions determine the thickness, attention should be paid to the compaction, smooth, in the shade horn place should be wiped into 50 mm above the arc shape. In the whole process of Pu wipe pay attention to ensure the smoothness.

3 node additional layer enhancement: in the node parts (such as the Yin and yang angle, corner, construction joints, after the cast strip, deformation joints, wall tube, etc.) should be done with an additional layer.

4. The large surface self adhered membrane Putie: to expose self adhered membrane under the surface of the insulating film, the coil tiles in plastering cement mortar base, the first piece of coiled material shop posted after re apply cement mortar, paving the second coil, and so on.

. provided plasma exhaust: beating the membrane surface with wood trowel or rubber plate, slurry and self adhered membrane surface accumulation of air will be discharged, tightly jointed together the sheet with cement mortar.

. overlapping edges paste: according to the actual situation at the scene, can choose paving material of overlapping edges paste or mortar passionate enough strength to overlapping edges paste; overlapping edges paste, the two pieces of sheet isolation film overlapping part to expose, upper coil flat posted on the lower layer coil, sheet lap width not less than 100mm.

7 protection layer construction: waterproof layer construction is completed, the acceptance of qualified, with cement mortar or fine stone concrete as a protective layer.
