Which is better polyethylene low foaming interval double sided tape for curtain wall?

The advertising brand has Jingke Industrial.

Cross-linked bridging polyethylene low foaming material (also known as chemical cross-linked polyethylene foaming material) is referred to as XPE, the product is based on low-density polyethylene (LDPE) and ethylene-vinyl acetate copolymer (EVA) as the main raw materials, adding foaming agent AC and other chemical raw materials, through mixing, processing, forming, and then through foaming, shaping, post-treatment and other series of processing technology to produce a relatively fine, independent closed-cell foam material, its relatively flat appearance, excellent resilience, high chemical strength, Excellent thermal insulation, water resistance, aging resistance, high temperature resistance, chemical resistance and excellent weather resistance. It can also carry out a variety of simple and complex secondary processing, or laminate with other materials for further processing. Changing the formulation appropriately can also give it other properties such as flame retardancy.

It has the advantages of high foaming rate, low density, thin thickness, smooth surface, non-toxic, odorless, high elasticity, and easy secondary processing. At present, it is widely used in transportation (automotive interior) industry, sports (leisure) industry, tourism goods industry, construction industry, decoration industry, refrigeration industry, health care industry and other industries.

It is recommended to use EVA double-sided foam tape, which will have a higher hardness and belong to the low-foaming category of double-sided tape.

This dosage is very large, at least hundreds of thousands of square meters per year, and the products commonly used on the market are mainly 3M.

Shanghai Yuguang:

Low foaming indicates that its density is small, the intermolecular interval is large, and it naturally has a certain degree of air permeability.

The commonly used specifications of double-sided adhesive strips for curtain walls are 6mm thick and 8mm thick.

Curtain wall double-sided tape is mainly used for curtain wall double-sided fixing, door and window sealing waterproof, insulating glass, furniture, etc. It can also be used for glass positioning and gap padding.

The double-sided adhesive material used for the curtain wall is polyurethane live polyethylene low-foam or god-cavity blind material coated with glue on both sides.

In recent years, developers have paid more and more attention to the quality of real estate, and many new exterior wall materials have emerged, and the exterior wall materials on the market mainly include: coatings, face bricks, stones, aluminum plates, glass curtain walls, etc., and the more common ones in residential buildings are face bricks and coatings.

1. Exterior wall coatings.

The advantages of exterior wall coating are that it is more economical, the overall sense is strong, the decoration is good, the construction is simple, the construction period is short, the work efficiency is high, the maintenance is convenient, the first investment cost is low, even if the peeling and falling off there is no danger of hurting people, and it is easy to renew, enrich the different requirements of buildings in different periods, and can enhance the image of the building after maintenance and updating. At the same time, adding waterproofing agent to the paint can solve the waterproofing problem in one application. Its disadvantage is that it has a poor texture and is prone to contamination, discoloration, peeling, and cracking.

At the same time, the life is short, even if the paint claimed to have a life of 10 years, it may need to be cleaned and repainted in less than 5 years, and this cost still needs to be "paid by the owner", which is generally taken out of the house maintenance funds paid by the owner. In addition, the exterior wall with paint shrinks after the cement solidifies, which will produce some cracks on the façade, although the new elastic coating can solve this problem, but the first elastic coating is also more expensive.

Second, the exterior wall bricks.

Exterior wall tiles are generally ceramic, and there are glazed and unglazed. In appearance, the surface is glossy or matte, or the surface is light and flat and the surface is rough, that is, it has a different texture. Its advantages are sturdy and durable, with good durability and texture, bright colors and rich decorative effects, and has the characteristics of easy cleaning, fire resistance, water resistance, wear resistance, corrosion resistance and low maintenance costs.

Durability includes dirt resistance, old resistance, scrub resistance, and long life, especially in areas with large environmental pollution and air dust, which undoubtedly has great advantages. Its disadvantages are that the first input cost is higher, the pasting requirements are higher, the construction is difficult, and the construction technology is not too hard, which is easy to cause falling off and hurting people. At the same time, waterproofing materials must be used additionally to solve the waterproofing problem.

From an environmental point of view, the use of acid in the cleaning process can cause air pollution. Special attention should be paid to the fact that once the water seepage problem occurs on the exterior wall of the surface brick, it is difficult to find the location of the water seepage, which will bring a lot of trouble to future maintenance.

3. Stone. Stone generally refers to natural facing stone (marble, granite) and artificial stone (cultural stone). Natural facing stone has a good decorative effect and is durable, but the cost is high. Artificial stone has the advantages of light weight, high strength, corrosion resistance, low quality and convenient construction.

Marble has the advantages of smooth surface, strong corrosion resistance, wind resistance, rain resistance, etc., which can play a good role in the cleanliness and solidity of the façade. Granite has the characteristics of compact structure, uniform structure, hard texture, wear-resistant, acid-resistant, and generous appearance. Because of its scrubbing resistance, stone is generally used in the dirty environment of the first and second floors of the building, and the radiation it produces will have a bad impact on the human body, and its own weight is relatively large, so it is usually not used in the whole high-rise building.
