With the rapid development of our national economy and continuous improvement of people's living standards, as well as the improvement of the architectural design concept of "humanity to architecture", the buildings are more and more developed in the direction of high, high, and multifunctional. Therefore, building curtain wall products are bound to develop towards the direction of high technology and multi-function, to adapt to people's increasing awareness of environmental protection and energy saving, and meet the market demand for weather smart building wrap and building curtain wall function.
Various measures taken to prevent or reduce the corrosion of metal and prolong its service life are called protective methods. The use of insulation (the term "insulation" is provided by the industry encyclopedia) protective layer to isolate the metal from the corrosive medium, and eliminate the corrosion galvanic cell conditions, that is, the use of a protective layer to prevent metal corrosion is the most widely used method at present. The common protective layer has a metal protective layer, a chemical protective layer, and a non-metallic protective layer three.
The house wrap on metal building is a metal or alloy with cathode or anode protection, through electroplating, spraying, electroless plating, hot plating, and osmotic plating, forming a metal protective layer (film) on the surface of the metal that needs protection to isolate the contact between the metal and the medium, or the use of electrochemical protection to protect the metal, thereby preventing corrosion. However, relatively speaking, the metal protective layer is heavy and has poor air permeability.
The chemical protective layer is a chemical or electrochemical method to generate a compound film with corrosion resistance on the surface of the metal, to isolate the corrosive medium and metal contact to prevent the corrosion of the metal. Examples include the oxidation of steel (Phelan) and the electrochemical oxidation of aluminum (entry "aluminum" provided by industry encyclopedia).
The non-metallic protective layer is the use of paint, plastic, and vapour barrier material, by brushing and spraying (entry "spraying" provided by the industry encyclopedia) and other methods, the formation of a protective film on the surface of the metal, so that the metal and the corrosive medium isolation, to prevent the corrosion of the metal.
Hypak Flashspun is not only 100% recyclable, but its waterproof and breathable performance can also resist rain erosion externally and prevent moisture accumulation internally. By covering the envelope, Hypak Flashspun waterproof building wrap enhances the air tightness and water tightness of the building, while making the moisture vapor within the envelope be expelled, effectively avoiding the damage of mold and condensation. Effective protection of buildings. Both inside and outside, so that the building can be fully protected.
Although Hypak Flashspun is thin and soft, flashspun fabric has very high strength, can block the invasion of wind and rain on the building, reduce air convection, effectively reduce heat loss, and protect the installed thermal insulation materials and building structure. In the application of easy construction, not easy to damage, aging, but also efficient wind resistance, to maintain a longer role (can be the same as the life of the building body).
