The bathroom is a place where water content is sufficient. The waterproof problem must be taken into account during the renovation. The waterproofing problems on the bathroom walls, floors and floors are particularly important. However, how to choose the waterproof material, which kind of waterproof material is better, and the cost is relatively low, Xiaobian introduced several for everyone.
For new house renovations, the bathroom and kitchen must be considered waterproof, especially the bathroom. As the most humid area in the home, the waterproofing of the ceiling, walls and floors is always put first, tiles and aluminum linings. The highest frequency of use. However, the waterproof paint that can turn water vapor like a lotus leaf is generally more and more popular. So, what are the common bathroom waterproof coatings, which brand of waterproof coating is good, and what is the difference between waterproof performance and cost?
Waterproof paint on water vapor like lotus leaf rolling
The wall of the home bathroom can be completely painted with a waterproof paint. Someone once used the water resistance of the home improvement paint instead of the lotus leaf, and the dewdrop would never penetrate into the lotus leaf. Waterproof paint is the effect. Professionally speaking, the special waterproof breathable molecules are added to the waterproof paint formula to form a dense paint film, making it impossible for water molecules to penetrate.
On the market, Nippon, Fenlin, Xijia, Longpai, Jinyun, Dufang, Asahi and other brands of home improvement coatings have good waterproof properties, among which Nippon and Fenlin are best known. Nippon's newest interior latex paint adopts a more scientific emulsion formula to enhance waterproof breathability and ensure that the wall surface is not attacked by water vapor. The Finling water-based waterproof coating uses a moisture-proof adhesive. The firmness of the paint film not only resists the moisture of the bathroom, but also can be applied to the exterior wall of the building.
Waterproof paint for bathroom wall requirements
The benefits of waterproof paint are not only convenient for construction, the effect is unique, but also one thing is good cleaning, but also to prevent moldy it. And because the waterproof paint is very viscous, it is most suitable for filling the pores of the wall surface. Even if the bathroom wall condition is not very good, the effect will not be affected.
With the addition of waterproof paint, the wall materials in the bathroom tend to be a combination of multiple trends, such as mosaic and waterproof latex paint, wood and waterproof paint used in combination, the wall and the ground can even be purely cement added paint, covered with waterproof paint, made Mottled natural effect, very artistic taste.
Coil (SBS elastomer modified bituminous membrane, polyethylene polypropylene waterproofing membrane), coatings (acrylic acid, polyurethane) and JS cement base were compared with new product L'Oreal mortar waterproofing agent. The following premise of comparing the prices of various types of bathroom waterproof materials is that all the indicators of the materials have reached the national standards and are constructed in accordance with the specifications.
Common material costs for waterproofing membranes
1, SBS, APP modified bitumen waterproof membrane: This type of waterproof material needs to be painted on the base surface before the construction of cold base oil, in order to achieve a solid base surface, improve the role of adhesive force, the coil is generally applied in the construction of 1 Layers, in the weak parts of pipelines, corners, etc., require additional construction reinforcement layers. Each coil needs to be overlapped horizontally and vertically, and special-shaped parts need to be cut. Generally, waste consumption accounts for about 20% of the total amount. In addition, these materials are classified into type I and type II according to the thickness and various indexes. In general, type II is better than type I. Therefore, the general I-type modified bitumen membrane material costs: 26 ~ 30 yuan /?. The cost of Type II modified bitumen waterproofing membranes is: 32-36 yuan/inch.
2. Polypropylene Polypropylene waterproofing membrane: This type of membrane is mainly classified according to the weight per square meter. Most of these waterproof materials are implemented in the corporate standard, and according to national regulations: All products that have relevant national standards, all indicators must be implemented in accordance with national standards, the thickness of polypropylene film polyethylene film produced by a molding process to achieve Above 0.5mm can meet the national industry policy requirements and inspection indicators. At present, most of the products in the market are 250g, 300g, 400g, etc., which can't reach this target, and the cost is as low as 3 to 5 yuan. The material cost of one-step polyethylene polypropylene waterproofing membrane that can meet the national standard is above 28 yuan/?.
The full ceramic ball bearings listed below are supplied with rings and balls made from zirconium dioxide (ZrO2). These zirconia bearings are available as full complement (no cage) or with cages made from PTFE, PEEK or 316 stainless steel.
These are non magnetic, non-conductive and highly corrosion resistant to most chemicals although ZrO2 bearings are not recommended for prolonged contact with steam. Full complement bearings or those with a 316 stainless cage can be used up to 400°C while bearings with a PEEK or PTFE cage can cope with temperatures of up to 250°C. For temperatures below -70°C, PTFE or 316 stainless steel cages are preferred. Standard radial clearance for full ceramic bearings is C0 but other clearances can be supplied to order.
ZrO2 ceramic bearings are generally used for their extreme temperature capabilities, excellent corrosion resistance or non-magnetic properties. Other sizes can be supplied on request.
The Description of Ceramic Bearings:
Compared to steel, Ceramic ball Bearings have many specific advantages. They offer superior corrosion and heat resistance, higher dimensional stability, and lower density, which facilitate high speed. Ceramics are superior to steel in heat and corrosion resistance, and are lightweight and extremely hard as well. Consequently, ceramic rolling bearings can be used in environments where conventional steel bearings cannot. That is to say, the superiority of these bearings makes it possible that they can be applied in some special environments.
Firstly, they can be used in corrosive environments. Compared to stainless steel bearings, hybrid and all Ceramic Bearing lasted three and twenty times longer respectively. It is presumed that water readily adheres to silicon nitride and forms a better lubrication film, leading to extended bearing life.
Secondly, they can be performed in corrosive agents. Generally, silicon nitride has excellent corrosion resistance. However, corrosion resistance varies depending on the type and quantity of sintering additives, and certain corrosive agents decrease in hardness and flexural strength. In such situation, it is can be proved that the carbide-based ceramic bearings are the most effective.
Thirdly, they can be used in high-temperature vacuum. An all-silicon nitride Ball Bearing with a self-lubricating laminated cage (mainly composed of MoS2) and with MoS2-coated rings and balls proved superior in durability in a high-temperature vacuum environment. Compared with the hybrid bearings, the all-ceramic bearing was superior in both dynamic frictional torque and life.
Fourthly, they can be performed with poor lubrication. As ceramics are extremely hard and have outstanding wear resistance, they outperform other materials in bearing life without lubrication. According to a test, the steel bearing seized within a short period while the hybrid and all 627 Ceramic Bearings, though sustaining wear, did not. And the all-ceramic bearing sustained considerably less wear than the hybrid bearing, indicating that its endurance life is much longer.
