What is film waterproofing? And Xu film waterproofing method
Waterproofing of coating film means that the surface of the structural layer with a certain waterproof ability is painted with a certain thickness of waterproof coating. Waterproof method of coating film According to the situation and applicable parts of the waterproof base. Reinforcing materials and buffer materials can be laid in the waterproof layer to achieve the purpose of improving the waterproof effect of the coating film and enhancing the strength and durability of the waterproof layer. Because of its good waterproof effect, simple and convenient construction, coating film waterproofing is especially suitable for structural waterproofing layers with complex surface shapes, so it has been widely used. For underground waterproofing and waterproofing of other projects.
What materials are the coating film waterproofing made of?
The coating film waterproof project is mainly composed of primer waterproof coating, wall reinforcement material, heat insulation material and protective material. The primer mainly includes synthetic resin, synthetic rubber and rubber asphalt (solvent or emulsion type) and other materials, which are used for brushing, spraying or troweling on the surface of the base layer and used as the base layer treatment material in the first stage of waterproof construction. Waterproof coatings mainly include polyurethane waterproof coatings, acrylic waterproof coatings, rubber asphalt waterproof coatings, neoprene waterproof coatings, silicone waterproof coatings and other waterproof coatings. It isolates the surface of the building from water, plays a role in waterproofing and sealing the building, and also plays a decorative role in beautifying the building. The matrix reinforcement materials mainly include glass fiber textiles, synthetic fiber textiles, synthetic fiber non-woven fabrics, etc. Its function is to increase the strength of the waterproof layer of the coating film, and when the base layer is cracked, it can prevent the coating film from cracking or creep rupture. ; At the same time, it can also prevent the coating film from falling. Thermal insulation materials, such as polystyrene boards or polystyrene boards, etc., play the role of thermal insulation and protection materials. Such as decorative coatings, protective buffer materials, etc., its role is to protect the waterproof coating from damage and to decorate and beautify building materials, such as polystyrene boards, etc., to play a role in thermal insulation.
What is waterproof coating? What are its basic performance characteristics?
Waterproof coating is a viscous liquid polymer synthetic material with no fixed shape at room temperature. After coating, a tough waterproof film is formed on the base surface through the volatilization of the solvent or the evaporation of water or the reaction and curing. The basic performance characteristics of waterproof coatings are as follows 1. The waterproof coating is a viscous liquid at room temperature. After coating and curing, it can form a seamless waterproof coating film. 2. The waterproof coating is especially suitable for waterproof construction at the detailed structures such as facades, yin and yang corners, pipes passing through the structural layer, protrusions, and narrow places. After curing, it can form a complete waterproof film on the surface of these complex parts. 3. The construction of waterproof coating is a cold operation, which is easy to operate and has low labor intensity. 4. The waterproof layer of the coating film formed after curing is light in weight, and most of the special-shaped roofs such as light shells are constructed with waterproof coatings. 5. The waterproof coating has good water resistance, weather resistance, acid and alkali resistance and excellent elongation performance, and can meet the needs of local deformation of the base layer. 6. The tensile strength of the waterproof layer of the coating film can be strengthened by adding a matrix reinforcement material. For some parts that are prone to leakage such as cracks in the base layer, structural joints, and pipe roots, it needs to be strengthened, strengthened, and repaired. . 7. The waterproof coating film generally relies on manual coating, and its thickness is difficult to achieve uniformity. Therefore, during construction, it is necessary to repeat the brushing in strict accordance with the operation method to ensure the minimum usage per unit area and ensure the coating film. Construction quality of waterproof layer.
Why should the toilet and bathroom waterproof be 1.8 meters high?
This mainly considers the safety and overall waterproof effect of the toilet and bathroom waterproof. Generally, the shower or sprinkler is installed at a height of about 1.8 meters. If the waterproofing is low, the long-term spraying will cause water to penetrate the wall, which will cause the wall to become mildewed, the wall decoration coating or the surface brick to peel off, etc., so that the waterproofing cannot be achieved. Effect. In principle, the non-shower wall can be 30mm, but in order to strengthen the waterproof effect, we uniformly make it 1.8 meters high, and the cost does not increase much. In addition, for the light body wall and self-built light body wall renovated in the toilet and bathroom, it is recommended that the waterproof height be at the top.
In the renovation process, when do you start waterproofing?
Home decoration, water and electricity reform first, after the completion of the water and electricity renovation, waterproofing must be done immediately. It should be noted that waterproofing should be done at the base of the structure as much as possible.
How long does the entire waterproofing process take?
Which waterproof material is the best for home decoration? Taking acrylic waterproof coating and JS waterproof coating as an example, it usually takes about 3 days to do waterproofing, and the basic treatment is generally 1-2 hours. Generally, the waterproof coating is applied 3 times, and the interval between each coating is 4-8 hours. Other waterproof materials According to the material manual. After the construction of the waterproof layer is completed, the complete drying time is about 12 hours. Generally, after the construction in the afternoon, the closed water test can be carried out at noon the next day.
Recent market analysis of polyurethane industry
Last week, the domestic BDO market trended loose, and the focus of discussions generally declined. In the face of the market atmosphere in this dilemma, the on-site trading operations became more light, and the spot market small order acceptance negotiations were adjusted to around 13,600-13,900 yuan / ton, and the focus was close to low range. At the end of this week, new orders are being negotiated in various downstream fields. Among them, the PTMEG market is expected to be more ideal under the positive atmosphere of the unified increase in spandex, and more sorting operations appear. However, the PBT and GBL markets are in weak demand, and the raw material market is even more down. Under the constraints of the current situation, it is difficult to be optimistic, so there is no expectation of improvement in the BDO market demand. In the supply-side market, supply changes are limited, and it may only increase unabated. The focus of discussions is expected to be adjusted slightly. It is expected that the domestic BDO market will continue to run weakly this week. It is not ruled out that the high range offers will decrease and low-price negotiations will be conducted. reproduce. In the morning, the BDO market in South China opened in a bleak atmosphere. Only orders were executed on the market, and there were few inquiries. There has been a decline before, but overall little has changed. At present, the bulk water acceptance negotiation in the field is around 13,700-13,900 yuan/ton, and the barreled supply is around 14,500-15,600 yuan/ton.
