Waterproofing membrane, building waterproofing? 200

First, asphalt-based waterproofing membrane.

Such materials are made of asphalt, because it is an organic compound that has been characterized as having low volatility and environmental impact.

Therefore, it is used more in ordinary residential and construction projects. However, asphalt-based waterproofing materials are made because of the use of benzene or nails.

Aldehydes are very polluting to the environment.

Second, polymer type waterproof sheet.

Such materials are mainly made of synthetic resin and rubber, which are relatively stable in nature, and are also resistant to aging and have a certain lifespan.

Extensibility of use, waterproof effect is very good, and it does not have much impact on the environment. However, the adhesive that goes with them is used, and it contains.

Great polluting factor.

Thirdly, polyurethane waterproof materials and acrylic acid waterproof coatings.

These two waterproofing materials are not harmful to the environment, but the chemical content must be controlled when they are used.

Otherwise, it will backfire and cause great pollution.

Fourth, silicone emulsion waterproof coatings.

This waterproof material is stable in nature, durable, has a certain anti-aging effect, is safe to use, non-toxic, odorless, and prevents points.

It can also prevent microorganisms from several liters, and it is a material that is easy to use and has a great waterproof effect.

In addition to this, there are some rubber silicone waterproofing materials, cement polymer waterproofing materials, aluminum-iron salt waterproofing agents, and so on, because of the use.

The ingredients are all different, and the scope and effect of use are also different. When using it, it is recommended that people have a certain understanding of the types of waterproof materials.

If you use this pack of waterproofing agent to make waterproof materials, you should fill it in and cover it with something or something else, and it's best to seal it as much as possible.

The pro-waterproof membrane is good, and the advantages of the waterproof membrane are: 1. Convenient construction, short construction period, no need to maintain after forming, not affected by temperature and tung burning, small environmental pollution 2, layer thickness is easy to grasp according to the design requirements, accurate calculation of materials, convenient construction site management, not easy to cut corners 3, uniform layer thickness, can effectively overcome the stress of the base layer when empty paving (the integrity of the waterproof layer can be maintained when large cracks occur in the base layer) Waterproof coating advantages: 1. Any complex base wheel which layer can be made into a continuous overall waterproof layer 2, the equipment is simple, The construction technology is easy to master3. The waterproof layer of the coating has 100% of the bonding surface with the base layer (except for the hollow paving method of the reinforcing layer used for cracks, nodes and other parts).

4. The leakage of the waterproof layer of the coating in the service life is mostly the cracking width of the base layer exceeding the extensibility of the waterproof coating, the cause of the leakage and the formation of the leakage are very easy to find, the warranty is very convenient, as long as a small amount of waterproof material repairs the cracks and damage parts, I hope I can help you <>

Do you have any other questions?

Waterproof membrane is used for waterproof dust Zheng construction can be curled into a roll-shaped flexible waterproof building materials products, is the first waterproof barrier of the whole project, its use is wide, not only can be used for the waterproof construction of the building history wall, roof, but also can be used for the waterproof construction of tunnels, highways, basements and other places, the role of the waterproof membrane is the same as the waterproof coating, but the performance is different in construction.

The asphalt waterproofing membrane input by the user for the first time is a sheet waterproof material that can be curled with base paper, fiber fabric and other carcass materials to infiltrate asphalt, and sprinkle powder, granular powder or sheet materials on the surface. Petroleum asphalt paper tire has the characteristics of low temperature flexibility, short durability of the waterproof layer, and low durability. During the construction of the underground waterproof layer, when the groundwater level is high, the groundwater should be lowered before the waterproof layer is paved, and the groundwater level is 750px below the bottom elevation of the waterproof layer, and maintained until the construction of the waterproof layer is completed; The surface of the base layer of the waterproof layer should be cleaned of dust and debris, and the residual mortar hard blocks and protruding parts on the surface should be cleaned, and there should be no hollowing, cracking, sand and peeling; The membrane and base treatment agent used in the waterproof layer are flammable materials, which should be stored separately, away from the fire source, and do a good job of preventing laughter and fire.

The material requirements of the membrane waterproof material must meet the specifications, there must be a factory quality certificate, and a test report issued by the corresponding qualification level testing department. The waterproof layer of the membrane is hollow, which occurs between the screed layer and the membrane, and is mostly at the seam of the membrane, because the screed layer is not dry, the sweat rate is large, the air removal is not complete, and the membrane is not firmly bonded; Leakage mostly occurs in pipe roots, floor drains, deformation joints, etc., expansion joints are not broken, resulting in tearing of the waterproof layer, and leakage may occur in other parts due to poor bonding, so the inspection should be strengthened during construction and careful operation.

3. Polymer synthetic materials - waterproof materials for coating films.

Synthetic polymer waterproof material is a one-component or multi-component waterproof coating prepared by synthetic rubber or synthetic resin as the main film-forming substance and adding its auxiliary materials. Waterproof coating is a kind of polymer synthetic material that presents a viscous liquid at room temperature. After being brushed on the surface of the base layer, through the volatilization of solvent or the evaporation of water or the chemical reaction between various components, a tough waterproof film is formed, which plays the role of waterproof and moisture-proof.

The waterproof layer of the coating film is complete, there are no joints, the weight is light, the construction is simple and convenient, it is easy to repair, and the service life is long.

Third, the construction technology of waterproof engineering.

1) The external insulation of the external wall is at the closing part of the external window.

With the continuous improvement of building energy-saving requirements, the external insulation technology of external walls has gradually been adopted by most projects, and the problem of rainwater leakage of external insulation in the closing part of the external window has also followed, and the rainwater leaks into the air layer of insulation along the closing part of the thermal insulation, and then penetrates into the interior along the external wall. Through research, it is found that the main reason for this problem is that the insulation closure is relatively weak, and if the construction quality control here is not good or the finished product protection work is not done well, it is easy to produce leakage problems. However, it is difficult to solve this problem by raising awareness of quality and the protection of finished products during construction, because it has been a hidden problem over time.

Therefore, through analysis and practice, it is believed that the following practice can be used for this purpose, before entering the text in the box.

Waterproofing membrane is commonly said to be made of different materials to make a synthetic waterproof membrane.

1. Waterproofing membrane can be divided into three types: asphalt waterproofing membrane, polymer modified waterproofing membrane and synthetic polymer waterproofing membrane.

2. Among them, asphalt waterproofing membrane is one of the most commonly used waterproof coatings, which is made of powdery isolation material after coating asphalt on the base tire.

3. When using waterproof membranes, it is important not to add water and mix the mortar mortar that has been dried and knotted before reuse, and the treatment of each construction node must be carried out in accordance with the relevant specifications, and it is best to add a layer of glass fiber mesh to the slag.
