The temperature stability of self-adhesive polymer waterproofing membrane refers to its ability to remain non flowing, non foaming, non sliding, and non brittle at high temperatures, that is, its ability to maintain its original function under certain temperature changes. Common targets such as heat resistance and heat resistance indicate its ability to withstand certain loads, stresses, or deformations without cracking. Common targets such as tensile strength, tensile strength, and cracking elongation indicate its ability to maintain flexibility at low temperatures, which is important for ensuring ease of construction and non brittle cracking. Common targets such as flexibility and low-temperature bending indicate its ability to withstand certain loads, stresses, or deformations without cracking.

Self adhesive polymer waterproofing membrane is suitable for waterproofing and moisture prevention in industrial and civil buildings such as roofs, basements, bathrooms, as well as SBS waterproofing membrane waterproofing in bridges, parking lots, swimming pools, tunnels, reservoirs and other buildings. This product uses flame melting method for convenient construction operation, safety, high construction efficiency, and can be constructed all year round. The aluminum foil surface membrane has reflective cooling effect. The SBS and other modified asphalt used in this product have high elasticity, good low-temperature flexibility, good temperature difference and anti fitting deformation ability. The adhesive fixed membrane waterproofing roof system is divided into light steel roof adhesive fixing system and concrete roof adhesive fixing system. The membrane also includes polymer waterproofing membrane, reactive adhesive polymer waterproofing membrane and roof waterproofing membrane.

The wet laying method self-adhesive waterproofing membrane is widely used in waterproofing construction at present. This self-adhesive waterproofing membrane is a polymer waterproofing membrane widely used in the construction industry. This polymer wet laying method self-adhesive waterproofing membrane has a very good service life in PVC waterproofing membrane during use, and has excellent aging resistance in terms of performance. Tensile strength is also one of the characteristics of this material.

The excellent performance of this wet laying self-adhesive waterproofing membrane during construction is not only due to the advantages of the wet laying self-adhesive waterproofing membrane itself, but also closely related to the maintenance method of this waterproofing material during construction.

So how should the maintenance of wet laid self-adhesive waterproofing membrane be carried out? When laying wet laid self-adhesive waterproofing membrane, full attention should be paid to the surrounding construction environment, especially in terms of temperature. The use temperature should be kept above minus 5 degrees Celsius to better enhance the performance of the waterproofing membrane. TPO waterproofing membrane, especially when using full adhesion method for waterproofing material construction, has different temperature requirements and should be kept above 5 degrees Celsius.

The method and advantages and disadvantages of laying the waterproof layer of the roll material.

1. Full adhesion method, also known as full adhesion method, is a traditional construction method that can be used by hot melt method, cold adhesion method, and self-adhesive method. Its advantages and disadvantages are that when used for three felt four oil asphalt waterproofing membrane, each layer has a certain thickness of mastic full adhesion, which can improve the waterproof performance. However, if the humidity of the leveling layer is high or the surface deformation is large, the waterproof layer is prone to bulging and cracking. Applicable conditions: the roof area is small, the roof structure deformation is small, and the leveling layer is dry.

2. Empty paving method.

The method is to stick the roll material to the base layer only within a certain width around it, and not to stick the rest. When laying, it should be at the eaves, ridges, and corners of the waterproof roll material with polymer self-adhesive film.

At the connection point of the protruding roof, the roll material and leveling layer should be fully bonded, with a bonding width of not less than 80mm. The lap joint between the roll materials should be fully bonded and layered.

When pasting, the rolls should be fully pasted between each other. Its advantages and disadvantages are: it can reduce the impact of base deformation on the waterproof layer, which is conducive to solving the problem of wrinkling and opening of the waterproof layer.

Crack problem, but due to the lack of adhesion between the waterproof layer and the base layer, once there is leakage, water will flow under the waterproof layer and it is difficult to find the leakage point.

3. Stick method.

The method is to use strip bonding between the roll and the base layer, with no less than 2 adhesive surfaces between each roll and the base layer, each with a width of no less than 150mm.

The overlapping of rolls should be fully bonded, and the stacking should also be fully bonded. Its advantages and disadvantages are: due to the liquid roll part of the roll not bonding with the base, it increases the waterproof layer to adapt to the base.

The deformation ability of the layer is beneficial in preventing the roll from bulging and cracking, but its disadvantage is that the operation is relatively complex, and some areas can reduce oil, which affects the waterproof performance.

Can.

4. Point sticking method.

The method is to use point bonding between the roll material and the base layer, requiring at least 5 bonding points per square meter, with each point area not less than 100mm × 100mm. The overlap of the roll material should be fully bonded, and the waterproof layer should also be fully bonded to the base layer within a certain range around it. When a punching machine is used for the first layer, it also belongs to point bonding. Its disadvantage is that it increases the ability of the waterproof layer to adapt to the deformation of the base layer, which is conducive to solving the problem of wrinkling and cracking of the waterproof layer. When a punched roll material is used for the first layer, it can only be used for multi-layer laying construction of the roll material, and the operation is relatively complex.
