How to clean the ETFE membrane fabric covered buildings if it is dirty? Although the ETFE membrane structure itself has a good cleaning function, it will eventually cause dirt accumulation due to the influence of external factors. For most membrane materials, cleaning can not extend the working life, if cleaning is not appropriate, it will also shorten its life. However, from the aspect of aesthetics, regular cleaning of the membrane structure can maintain the aesthetics of the membrane structure. At the same time, special cleaning agents should be used when cleaning.
First, let's take a look at the reasons for the accumulation of dirt in the ETFE membrane tensile roof , as follows:1. Air pollution.
2. The distance between deciduous trees and sticky pollen trees.
3. Local precipitation and frequency.
4. Feces of birds such as pigeons and seagulls.
5. The coating is inert without dust.
6. The degree of chemical contamination of the membrane fiber before weaving and coating.
The above points are the reasons for the accumulation of dirt in the tensile shade structures, and we try to avoid the formation as much as possible. If dirt really accumulates, we need to clean the tensile construction, but we must pay attention to some things when cleaning to avoid damage to the membrane structure. Specific notes are as follows:
1. Use the cleaning agent specified by the manufacturer and use the corresponding soft brush, sponge and cleaning equipment to clean the membrane surface, and use water to wash away the dust and cleaning agent on the membrane surface.
2. Membrane surface should not be stacked with foreign objects such as iron parts, chemicals or other colored materials for a long time.3. Let the cleaning agent act for a few minutes, but avoid drying the cleaning area.
4. Large particles of dust should be washed with water.
5. When cleaning the membrane surface, it is not suitable to use acidic or alkaline materials such as gasoline, alcohol, chlorine water and other materials to clean.
6. Stubborn stains may require high-concentration cleaning agent to scrub, but to avoid scraping off the surface layer of the membrane.
Why build a car parking shade canopies tensile structure? Here is the answer from BDiR: the reason for the construction of the car parking cover sun shade net sail and the production process.
Do you know that if the car is blowing in the sun and rain, will it be more than twice the original use period? It is like a car you originally used. It can be used for 10 years. There may be less than 3 years of use in the wind, the sun and the rain. Don't forget that the structure of the car is steel, and oxidative rust is inevitable, even if the advanced car is just the same. You can't see the naked eye inside, don't forget that the rain is acidic, it will speed up the erosion, the sun is also very scary, it will age, the wind is also the wind, it will erode, and the fabric membrane car parking sun shade can not only Wind and rain, you can also block high-altitude parabolic!
Sharm el-Sheikh is a desert city located at the southern end of the Sinai peninsula (Sinai), bordering the Gulf of Aqaba in the Red Sea, a small bay at the southeast end of the Sinai peninsula in Egypt. There are many small islands and reefs in the nearby sea, and the narrowest part of the deep water channel is only 300 meters, which is a holy place to visit. With bright sun and clear water, Sharm el-Sheikh attracts a large number of European and Israeli tourists every year.
Membrane shade structure is the most representative and promising architectural form in the 21st century. It breaks the pattern of pure linear architectural style, with its unique beautiful curved shape, the perfect combination of conciseness, crispness, rigidity and softness, strength and beauty, presents a refreshing feeling, and at the same time provides greater architectural designers Imagine and create space.
1. Excellent thermal insulation effect
It has good environmental protection, light transmission, and self-cleaning. The surface of the membrane is coated with PVDF (polyvinylidene fluoride) or titanium dioxide, which has good thermal insulation effect and can reflect 70% of the solar thermal energy. The fabric itself absorbs 17%, heat transfer 13%, and the light transmittance is more than 20%. After 10 years of direct sunlight, its brightness can still retain 70%.
2. Unique shape
Secondly, the translucency of the membrane ensures proper natural diffused light to illuminate the room. Larger span building space, due to its light weight, polyester structure membrane building can cover the space without a large span of internal support surface, which allows people to design and use building space flexibly and creatively. The membrane structure has an artistic shape that traditional roofs do not have.
3. Cover large span spaces
The architectural structures material used in the membrane structure is about one kilogram per square. Due to its light weight and the use of high-strength materials such as steel cables and steel structures, the force system is simple and reasonable-most of the force is transmitted by axial force, so the membrane The structure is suitable for spanning large spaces to form an open column-free large-span structural system.
4. Fire resistance and shock resistanceThe lightweight structure material used in the membrane structure building has excellent flame retardancy and high temperature resistance, so it can well meet the fire protection requirements. Due to its light weight, flexible structure and large deformation capacity, it has good seismic performance.
What material is the ETFE membrane structure air pillow made of? From the name point of view, it can be seen that the membrane structure air pillow is composed of ETFE material.
The ETFE is ethylene-tetrafluoroethylene copolymer. The thickness of ETFE membrane is usually less than 0.20mm, which is a kind of transparent membrane. This membrane material will be used in the Water Cube venue, with a unique and beautiful appearance.
ETFE membranes have a service life of at least 25-35 years and are ideal materials for permanent multi-layer movable roof structures. The membrane material is mostly used for two-layer or three-layer inflatable support structures with a span of 4 meters. It can also increase the membrane span according to the geometry and climatic conditions of special projects. The length of the membrane is easy to install as the standard, generally 15-30 meters. Small-span single-layer structures are also available in smaller sizes.
Therefore, ETFE membrane is a very popular in the tensile structure, but the technical difficulty is relatively high. At present, ETFE membrane structure air pillow materials mainly rely on imports, so the price is generally much more expensive than other membrane materials.

The archipelago extends from northwest to southeast and is 1,220 kilometers long and 96 kilometers wide. It consists of more than 700 islands and more than 2,000 coral reefs, with a total area of 13,878 square kilometers, of which more than 20 islands are inhabited.
What membrane materials are generally used for membrane structure car parking shade? Membrane structure is a new type of building structure developed in the middle of the 20th century. Membrane structure is made of a variety of high-strength thin-film materials and reinforcing members (steel frame, steel column or steel cable) through a certain way to produce a certain pre-tension stress inside In order to form a certain space shape, as a covering structure, and can bear a certain external load effect of a spatial structure form. There are many uses around us, such as carports, stands, landscapes, etc.
The membrane materials of tension fabric structure are mainly PVDF, PTFE and ETFE. Among them, PVDF and PTFE are the most used. As our common membrane structure carport is the most commonly used membrane structure building, most membrane structure carports are constructed with PVDF membrane materials.
PVDF membrane material: Poly (vinylidene fluoride), the English abbreviation PVDF, mainly refers to vinylidene fluoride homopolymer or copolymer of vinylidene fluoride and other small amount of fluorine-containing vinyl monomer, which has the characteristics of fluorine resin and general resin In addition to good chemical resistance, high temperature resistance, oxidation resistance, weather resistance, and radiation resistance, it also has special properties such as piezoelectricity, dielectricity, and thermoelectricity.
How can fabric tension structure buildings be shockproof? The construction of membrane structures often needs to consider the influence of natural factors. Earthquakes are one of the factors influencing natural disasters. Therefore, when constructing membrane buildings, earthquake prevention is one of the primary considerations of membrane structure engineering. We often see reports of earthquake disasters. Many buildings collapsed to the ground in an instant, and many people were sentimental for this. In recent years, the membrane structure has been welcomed by the construction industry because of its shockproof function. The membrane structure has brought the gospel to the construction industry.
The presentation of the lightweight structures is actually high-tech products. These high-tech products can bring us a better quality of life and guarantee. As the saying goes, natural disasters and man-made disasters cannot be avoided, but we can use modern high-tech compensation to minimize disasters and losses, which is what we want to see. Membrane structure is a product with the best fire resistance and shock resistance. This high-tech construction product uses the best flame retardant ingredients and high temperature resistant ingredients in the membrane materials, which is also the best place for its shock resistance. In addition, its overall structure is very light, and even in the event of an earthquake, it will not cause much damage, which is also one of the reasons for the good earthquake resistance.
The shock resistance of the tensile roof structure is well known, and the membrane structure has fast installation, beautiful modeling, short construction period, and variability in the curved surface. Its deformation ability and expandability lead to the earthquake resistance of 10,000 times stronger than that of the traditional carport. Its structural composition is inseparable. In fact, the membrane structure is completed by four major processes such as body shape planning, initial balance planning, load analysis, and cutting analysis. As for any membrane structure, there is no stress-free condition at any time, so its rigidity and stability are very strong. Therefore, its cutting should be completed under the condition of accurate structural deformation and stress, which also creates a place with extremely strong earthquake resistance.
Nowadays, as long as you think of the place where the sunshade and the rain are sheltered, you can choose the membrane structure awning. Tensile roof engineering is a new form of building structure that has been applied to various building structures, such as cultural and entertainment facilities, park greening, transportation, schools Wait, play this indispensable role in life.
The awning of the canopy structures is novel and beautiful, and the shape is free. It is a beautiful landscape in itself, and it can protect the sun from the rain.
Let's take a look at how the playground canopy used in the school is built.
A new type of construction project "membrane structure" awning because of its good light transmission performance (light transmittance 20%). Exposure to sunlight will not cause discoloration, fogging, or poor light transmission. Its light weight guarantees the safety of people and things under the shed, and has a good shading effect. After market research, the sports stand with lightweight structures was finally considered to be the best choice.
The material of the playground shade structures is a new type of high-strength composite material, which is durable, waterproof, anti-corrosion, anti-ultraviolet, thermal insulation, etc. After preparing the steel structure, membrane material and other materials, after the on-site proportion comparison, the materials are welded and bolted Connect so that the installation can be completed.

The United Arab Emirates is located in the east of the Arabian Peninsula, bordering the Persian Gulf in the north, Qatar in the northwest, bordering Saudi Arabia in the west and south, and the coastline adjacent to Oman in the east and northeast is 734 kilometers long, with a total area of 83600 square kilometers. What about the pvc shade structure form in it ?
1. Suspension cable
Suspension cable is the most simple way of tensioning. There is only cable between the corner of the membrane and the support. However, due to the performance of the membrane material, it is impossible to achieve a large span for pure anchor-tensioned curved surfaces. In harsh areas, it is not advisable to exceed the construction span of a single modeling unit.
This type of support is suitable for small-scale membrane construction.
2. Cable Truss
On the basis of suspension cable tension, the use of structural cable truss structure fulcrum effectively reduces the unit span, the combination of multiple membrane units can form a large-area model. The cable truss is a large-span structural form with light visual effects, and it is also an excellent choice to cooperate with the tensile roofing structures.
3. Cable Dome
The cable dome and the membrane are a seamless and unparalleled combination, which best embodies the idea of "use less and use more". However, the high technical requirements of the cable dome, the difficulty of construction and the large cost are the difficulties in the domestic application.
