The inner layer of the tape is sticky.

According to the different rubber materials, self-adhesive tapes can be divided into ethylene propylene rubber self-adhesive tapes, ethylene propylene rubber posture wide and butyl rubber waterproof belts, silicone rubber belts, etc. 2.It can also be divided into high-pressure rubber self-adhesive tape, low-pressure rubber self-adhesive tape, waterproof tape, semi-conductive tape, trace pure electric stress control tape, anti-arc silicone rubber tape, etc.

Summary. Generally speaking, self-adhesive with the overlying surface material (polymer), such as HDPE film, polymer polypropylene, EVA, etc., can enhance the waterproof strength of the self-adhesive membrane, and the tear resistance is collectively referred to as polymer self-adhesive waterproof membrane. ——

Generally speaking, the surface material (polymer) of the self-adhesive silver coating, such as HDPE film, polymer polypropylene, EVA, etc., which can enhance the waterproof strength and tear resistance of the self-adhesive membrane, is called the polymer self-adhesive leakage waterproof membrane. ——

It is the difference between the reaction bonding polymer waterproofing membrane and the SAM921 high-strength self-adhesive asphalt waterproofing membrane.

Hello, the biggest difference between reactive adhesive bush bonding materials and self-adhesive materials is that one uses a medium and the other does not. To put it simply, the reaction bonding waterproof material is to add some cement to mix water when bonding, and there is a kind of cement called silicate that will form a chemical reaction with the waterproof material, and then bond together. The self-adhesive one is relatively simple, tear off the separator film, and cover it with the waterproof place

Polymer self-adhesive membrane waterproofing membrane is a kind of special high-density Xinhuachun thermoplastic polyethylene membrane as the waterproof substrate, which reacts and consolidates with liquid concrete slurry, and is composed of a polymer self-adhesive film covering the bucket surface, a protective layer and an isolation layer that resists environmental changes.

The polymer self-adhesive film pre-paved waterproofing membrane has simple requirements for the base layer, only requires a minimum of surface treatment, does not need primer oil or hot gas to dry the wet base layer, and has no volatile properties. When the concrete base reaches the strength that can be used by people, it can be constructed. The polymer self-adhesive film pre-paved waterproofing membrane has a wide range of construction temperatures, and can be constructed in many seasons throughout the year. Slip resistant.

When renovating a house, various types of waterproofing materials are used. What is the polymer self-adhesive film waterproofing membrane? This site will take you to find out.

The polymer self-adhesive film anti-line base water membrane is a special polymer self-adhesive film reaction bonding between the slurry and the membrane adhesive layer when pouring concrete, so that the membrane and the concrete structure layer are permanently bonded with a source of long-term bonding, and there is no hidden danger of water channeling in the middle. Even if the attack membrane is partially damaged, the water outlet point will be limited to a small range, which improves the maintenance reliability of the waterproof layer.

Polymer self-adhesive membrane waterproofing membrane is a waterproof membrane composed of polymer sheet, self-adhesive rubber asphalt rubber, separator film (or pressure-sensitive polymer adhesive layer and unique formula of particle layer), the membrane combines the advantages of polymer waterproofing membrane and self-adhesive waterproofing membrane, not only has high puncture resistance, weather resistance, high and low temperature resistance, self-healing and other properties, but also adopts the pre-paved anti-adhesive construction method, which can be reacted and combined with concrete slurry to form a gapless combination of waterproof layer and concrete structure, and eliminate interlayer water channeling. Effectively improve the reliability of the waterproof system.

Now when building a house, you need to do the corresponding waterproofing project on the roof or balcony, the roof and balcony are exposed to the outside all the year round, and the perennial sun and rain will inevitably crack the wall to cause water seepage. So what are the construction methods of polymer composite self-adhesive waterproofing membrane? Let's take a look.

Compared with other waterproof materials, the material properties of the polymer composite self-adhesive waterproofing membrane are more excellent, and the super elastic tensile resistance makes the membrane ensure that the service life is longer under normal maintenance, so that the owner can reduce the cost of maintenance and renovation.

cold bonding; This construction process is a construction method in which the coil is pasted to the base layer by cold work using a special supporting adhesive for the coil, which is called the cold adhesive method. It is necessary to first apply special glue to the base and the surface of the coil, wait for the glue to dry to the point that it is not sticky, close and paste the coil and compact it with a pressure roller, and then fold the other part that is not folded, and so on, paste it firmly and compact, and finally weld the seam.

hot air welding; This kind of construction trace leather art is a construction method that uses hot air to heat the adhesive surface of the thermoplastic coil to bond the seam of the coil and the coil. Lay the coil at the position to be paved, adjust the alignment according to the position of the elastic line, and evenly apply the adhesive on the roof base and the bottom surface of the coil with the roller brush, and do not apply glue to the lap seam welding part. When the adhesive solvent volatilizes and does not stick to the touch, the coil can be laid on the roof base layer and compacted with pressure rollers to exhaust the air at the bottom of the coil.

The construction method is roughly the above two, in addition, it is recommended that you choose a professional construction team when choosing a construction team, only professional construction can play the maximum effect of waterproof materials, so that the owner does not have any worries when living in the house in the future.
