Self-adhesive Metal Film Modified Asphalt Waterproofing Membrane

Description

For non-upper exposed roofing, a layer of metal high tempera­ture resistant aluminum foil is applied on the surface of the coiled material, which improves the heat resistance and service life of the coiled material, in 2015 used in Guangzhou Toyota 200,000 square parts factory roof, so far no penetration, and achieved 15 degrees of cooling, sound insulation and water­proof functions.

SELF-ADHESIVE COIL (DRY LAYING METHOD)

1) Base treatment—-> additional layer construction—-> large surface construction—-> exhaust compaction—-> closed water test
2) When the rolling material is pasted, the self-adhesive bottom surface isolation paper should be torn. Large area should be placed before the additional layer of Yin and Yang Angle and node sealing treatment.
3) When rolling the roll, the waterproof roll should be slightly tightened, not too slack, the air under the roll should be excluded, and the pressing material should be compacted, and the bond should be firm. After plastered 24 less than shall not be water, should do a good job of product protection measures.
4) The site construction temperature must be greater than S’C. In case of low temperature, the coil can be heated by a hot fan and then pasted again.

SELF-ADHESIVE COIL (WET PAVING METHOD)
■ Base treatment: the base should be dry, solid, smooth, clean, no sand, dust and dirt. The rolling material is bonded to the base with cement slurry or cement mortar: when the cement glue is used, the dosage of rubber powder is 3%-5°/o of the weight of the cement; When cement mortar is used, the ratio is cement: medium sand =1:2. The actual water addition needs to be combined with the moisture level of the base site. It is recommended to use ordinary Portland cement with strength grade 42.SR. After mixing the cement slurry and cement mortar evenly, scrape and apply to the base.
■ Large surface construction: lift the coil to the predetermined position to be laid, pre-spread the coil, fully release the stress, set the reference line, lift the isolation film on the bottom surface of the coil, set one end of the coil, and then push the coil while rolling to both sides and the front with the press roll exhaust adhesive maintenance: maintenance for 48 hours after the completion of the coil laying (the specific time depends on the ambient temperature, under normal circumstances, The higher the temperature, the shorter the time.)

Matters needing attention

1) Coil should be stored in a dry and ventilated envi­ronment. Different types and specifications of coil should be stacked separately.
2) The storage temperature is not more than 45° C, the horizontal storage of the coil stacking height is not more than five layers, vertical storage single-layer stacking.
