The testing of elastomer-modified bitumen waterproof membrane is based on the elastic line. Trial laying: pop up the control line on the base coating according to the actual overlap area, and strictly follow the glue control line for trial laying and the actual glue laying of the coil to ensure that the coil is lapped. The connecting width is 6-7cm (there is a mark on the coil). According to the characteristics of the site, determine the elastic line density to ensure that the coil is pasted smoothly and will not be skewed due to accumulated errors. The coils should be laid in place for a trial first, and the actual gluing can be started only after the correct shape is cut according to the needs. Node processing.
Waterproof membranes have gradually transferred from unenvironmental engineering membranes to environmentally friendly household membrane manufacturers. This new business opportunity will make it lasting for a long time in the future. Polymer environmentally friendly waterproof membranes, with their environmentally friendly, durable, sturdy, easy to use and other characteristics, quickly enter ordinary households, so they have created a huge market for waterproof membranes, and the market prospects are inexhaustible. So, on the whole, whether it is engineering construction or the civilian market with a family as a unit, the prospects for waterproofing membranes are very broad.

Elastomer-modified bitumen waterproofing membrane is tested according to the SBS waterproofing membrane is made of styrene-butadiene-styrene (SBS) thermoplastic elastomer as the modifier asphalt as the impregnating and coating material, and the upper surface is covered with polymer A sheet-shaped waterproofing membrane made of vinyl film, fine sand, mineral sheet (grain) material or aluminum foil, copper foil and other insulating materials that can be curled. Introduction. SBS waterproof membrane combines cleverly mixed SBS (--) rubber-modified asphalt waterproofing with high-quality reinforced carrier through advanced production machinery.
Self-adhesive waterproofing membrane has the characteristics of cold construction, strong aging resistance, better adhesion, and reactivity. The main technical difficulty lies in the preparation of modified asphalt glue. The configuration of reactive modified asphalt glue can react with cement slurry. Bonding to form a skin type. At present, the products are widely used in waterproof engineering of construction, pipeline, subway, railway and other projects. The southern part of my country, especially Guangdong and Hainan, are affected by tropical and subtropical climates. They are in a hot and rainy state throughout the year. In the north, it is freezing, freezing and windy and sandy.
If there is a crack at the root of the deformed joint wall and water is leaking, the coil at the crack should be cut open. After the base layer is expanded, the waterproof sealing paste is inserted. After the coil strip is empty, the original waterproof layer is repaired and the original waterproof layer is strengthened. When the coiled material on the top surface of the deformation joint wall is cracked or damaged, the concrete cover plate should be removed and repaired again. Water falls and leaks. Phenomenon. Water leaks around the water fall, and some water fall surface is higher than the waterproof layer and water accumulates, or because the water fall is small, it is blocked and overflows. Must meet the design requirements. Mainly check the factory certificate, quality inspection report and on-site sampling re-inspection report, and check whether the specifications, model, thickness and other physical properties of polyethylene polypropylene fiber in the quality inspection report meet the design requirements. At the same time, whether the thickness of the polyethylene polypropylene fiber is lower than the design requirements is measured on the spot, and the actual construction often appears to be shoddy. The waterproof material is the basis for ensuring the quality of the bathroom waterproof layer, and the use of unqualified materials is strictly prohibited. Use a scraper to push to compact and remove air bubbles and excess waterproof adhesive slurry under the coil. Polyethylene polypropylene fiber waterproof quality acceptance for bathroom. Material inspection and acceptance: Polyethylene West Energy Coil and its supporting materials.
Laying and bonding of large surface coils. ◆Horizontal flat coiled material covered with heavy objects and the base layer should be empty. For roofing projects where the waterproof layer is exposed, the coiled material and the base layer should be sticky, point sticky, or full. The coil and the coil must be fully sticky. ◆The coil and base layer of the vertical facade and the coil and the coil must be fully glued. ◆The overlap of the lap coil and the coil should generally be the post-laying coil laps on the front-laying coil, and the full width of the lap area should meet the requirements of the relevant specifications.
In addition to wind resistance and waterproof performance, the waterproof membrane has an ideal sound insulation effect, which can well absorb and reduce the impact of rain on the roof and other noises, ensuring a quiet and high-quality living condition. The painting of the waterproof membrane has a lot to do with the condition of the ground base layer. Treat the base layer well before painting. The more uneven the base layer, the more paint will be used. Therefore, before painting the waterproof membrane, it is better to simply treat the base layer and try to make the base layer smooth. Paste the turn-over mesh cloth. Wherever the exposed side of the polystyrene board is pasted, it should be treated with mesh cloth. The 80mm width of the grid cloth not less than 200mm wide is firmly pasted on the base surface with special bonding mortar, and the remaining grid cloth is turned over when the polystyrene board is pasted later. Paste polystyrene board. The standard size of polystyrene board for external thermal insulation is 600mm900mm and 600mm1200mm. Non-standard sizes or local irregularities can be cut on site. The corners of the whole wall can be used for polystyrene board with a size of more than 300mm. Can't stay in the four corners of the door and window.
