This requires that the cleaning company's construction personnel have a very rich experience in high-level cleaning operations, and have a good management team and excellent self-safety protection measures. If you have any need in this area, you may wish to follow me to learn about the cleaning expertise of the external walls of the building .
Building exterior wall cleaning what conditions
1. Climatic conditions: The cleanliness of the external walls must be conducted in good weather conditions, and the wind power should be less than 5 levels. Above level 5 stop working. In addition, it is not suitable for exterior wall cleaning under conditions of rain, snowfall, poor visibility of fog, high temperatures (above 38 degrees), and low temperatures (below 0 degrees Celsius).

3, equipment conditions: the external wall cleaning equipment must be in good condition, such as the hanging board hairiness, some silk strands gradually cracked phenomenon should be updated immediately.
First, special tools
Work rope, safety rope, hanging board (seat board), safety belt, self-locking device, U-shaped card, work bucket, high-pressure water pipe, glass set tool, board brush, rubber gloves, medicine sprayer, etc.
1, the work rope: material is nylon, specifications: diameter of 20 mm, role: mainly used for hanging plate-type seat plate hanging, climbing operations. The work rope forms a high-altitude hanging board series by connecting the hanging board through a movable joint in the slide fastener. The self-locking hook on the lifeline and the upper body's safety belt is connected to form a safety system for the ascending person.
2, safety rope: material for high-strength wire, specifications: diameter: 18mm-20mm, role: mainly used with the work rope use. The high-altitude personnel hangs on the work rope through the seat plate, and the self-locking buckle of the seat belt is connected to the safety rope by the self-locking device, which can ensure the increase of the safety factor.
3, Hanging plate: also known as the seat plate, made of a combination of shrinking wood, sling made of fiber woven, all have a certain tensile strength. Role: When the crane is under high altitude, the high-altitude personnel will fall and slide on the hanging board. The non-slip plate break load is greater than 4400 newtons.
4, seat belt: made of fiber woven material. The safety belt is composed of two shoulders and a waist belt. It is connected with the work rope through a self-locking hook.
5, self-locking device: Made of stainless steel. Function: When connecting the safety belt and the safety rope, when the high-level construction personnel falls due to the breakage of the working rope, the self-locking device of the self-locking hook will be locked by the weight of the human body, so that the falling person will be stopped by the life rope.
6, U-type card: U-shaped buckle made of 16mm high-strength steel, and a bolted pin connection.
7, glass suits tools: Including: waterer, glass scraper, marble blade, extension rod, absorbent sponge, plastic strips. Role: For a variety of mirror surface.
8, high pressure water pipe: transparent plastic hose, high pressure hose.
Second, special agents
There are many brands of cleaning agents on the market: US Johnson, Chaobao, and Collier.

4. Special cleaning fluid characteristics for curtain wall: This product contains no solvent, no skin damage, no environmental pollution. After using this product, easy to dry, leaving no water marks, and a layer of bright protective film on the glass surface, the glass surface has a dust barrier effect and increase the gloss. Uses: glass curtain wall, coated glass, radiation protection glass, mirror metal surface of various buildings. Usage: According to the degree of dirt on the surface of the coated glass or aluminum alloy, dilute it after use. When cleaning, use a professional wiper to apply the cleaner to the glass, then use professional glass to dry it. Exterior wall decoration materials include granite, glass, aluminum alloy, stainless steel, glazed tiles, and paint. Granite: It has the features of compact structure, uniform texture, hard texture, abrasion resistance, acid resistance, and appearance. Note: According to the characteristics of granite, cleaning agents should be used when cleaning, and alkaline chemicals should not be used. Architectural glass: Silica glass with silica as its main component. The raw materials for producing glass include quartz sand, sodium carbonate, and calcium carbonate. Note: Since the main component of architectural glass is silicate, neutral agents should be used. Aluminum alloy: It has the advantages of water impermeability, durability and good machinability. Stainless steel: A type of alloy steel that is produced by adding alloying elements to carbon steel. Has excellent corrosion resistance. Note: Some agents will damage the surface of stainless steel, so special agents should be used.
Third, the workflow
1. Transport aerial work tools to the top of the building;
2. Select a fixed point to secure the work rope and safety rope, put the rope down the building, and use a carpet pad to place the rope and the floor joint to be well-matched (to prevent the building from wearing out the rope);
3. The high-altitude personnel backs up the safety belt, passes the seat plate to the work rope through the U-shaped card, puts the tool into the working barrel, and then pushes the working barrel onto the seat board and fixes it firmly;
4. Attach one end of the self-locking device to the safety rope and the other end to the safety belt;
5. After being thoroughly inspected and passed by the security officer, the operator shall be on the seat plate;
6. High-altitude personnel adjust the work ropes themselves to tighten them and confirm that they are seated and begin cleaning work. Matters needing attention: should pay attention to the rope to avoid edges and corners, or sharp, to prevent damage to the rope, where high-voltage lines can not be dropped. Weather conditions: In the wind is greater than 5 above, thunderstorm weather can not be dropped.
