To decorate the bathroom, the most important thing to notice is waterproofing. In waterproof engineering, waterproof coatings are really essential. At present, the common waterproof coatings on the market include polyurethanes, acrylics, and polymer cements. So, what good bathroom waterproof material it? In fact, these three waterproof coating have advantages and disadvantages, what we now take a look at the bathroom waterproof material with it!
First, polyurethane waterproof coating
Polyurethane waterproof coating mainly consists of isocyanate-containing prepolymers obtained from chemical reactions such as isocyanate and polyether, and is processed with catalysts, anhydrous additives, and solvents.
advantage:
First of all, its coating film has a high-strength tear-resistance performance, very good adaptability to the stretching and cracking of the base layer, and excellent elasticity;
Second, as far as environmental protection is concerned, polyurethane waterproof coatings are non-toxic, green, and will not harm the human body and do not pollute the environment. They are suitable for indoor use.
Then, in terms of its physical properties, the polyurethane type waterproof coating has strong adhesive force, good weather resistance, dense coating, and good waterproof effect. The waterproof coating has strong adhesive force and can penetrate into the gap of the base surface. When it meets the high and low temperature, it will not melt or crack, and the performance is stable. Moreover, its coating film density also leads to good sealing performance and is not easy to leak water.
Finally, the polyurethane waterproof coating has a very light texture, does not increase the load on the building, and it can freely mix colors, and it can be painted easily in a bathroom with a complex structure or color requirements.
Disadvantages:
1, the price is expensive. The so-called "a penny of a cargo," polyurethane waterproof coating used more expensive chemical materials, high cost, so its price is more expensive!
2, odor, polyurethane waterproof coating has a certain amount of odor, just pay attention to the need to pay attention to open the window ventilation and flavor; In addition, we must also note that the black polyurethane coating is not environmentally friendly, nor beautiful!
3, requiring high construction technology. Polyurethane waterproof coatings are not as uniform as polymer waterproof coatings. If you want to achieve uniformity, you need to have a smooth base wall, an old construction technique, and strict implementation of construction specifications. There is a certain degree of difficulty!
Second, acrylic waterproof coating
Acrylic waterproof coating is based on acrylate copolymer or pure propionate emulsion as the main material, plus some auxiliary materials to form a single component waterproof coating.
advantage:
Acrylic waterproof coating has good weatherability, structural stability is stable from -30 degrees to 80 degrees, and its ductility is also very good. It can effectively prevent wall sinking or cracking caused by coating cracking, leakage water seepage phenomenon; In addition, it also has the advantages of convenient construction, fast drying speed, and environmental protection.
Disadvantages:
1. The construction environment is limited. Acrylic waterproof coatings cannot be applied at temperatures below -4°C or on rainy days, and low-temperature or humid, non-ventilated environments can easily affect the effect of water-repellent coatings after film formation.
2, after construction, to check whether there are weak links, because the waterproof coating is paint after all, improper construction techniques, easily lead to uneven coating.
Third, polymer cement waterproof coating
Polymer cement waterproof coating, the main material is organic polymer emulsion and inorganic powder, mainly water as the dispersion medium, is a very green and environmentally friendly waterproof coating.
advantage:
The biggest advantage is that it is green and environmentally friendly. It uses water as a dispersion medium and is non-toxic and odorless. It has a wide range of uses and can be used for exterior walls and roofs. It can be effectively combined with decorative walls, cement mortar walls, and tile surfaces, and has strong adhesion. Can also be used indoors; at the same time using the emulsion coating and cement, soft and soft, effective waterproof!
Disadvantages:
The cost is very high, the price of one square meter is as high as ten yuan; the construction requirements are high, and it must be sunny at temperatures above 5 degrees Celsius, and rainy weather is suitable for construction.
Four, three kinds of material waterproof performance contrast
In terms of waterproof performance, the three waterproof materials can be ranked as follows: polyurethane waterproof coating> acrylic waterproof coating> polymer cement waterproof coating.
What about the good for the bathroom waterproof material content, small series to introduce here, we want to help! Bathroom waterproof must be done well, otherwise the household downstairs home will become a water curtain hole! For more information, please follow this site!

Gate valve is a relatively common general-purpose valve, the use of a wide range of applications, mainly in water conservancy, metallurgy and other industries, its extensive use of performance has been recognized by the market.
Gate valve structure: gate valve is the use of the gate and seat to control the opening and closing of the valve. Gate valve mainly has a valve body, valve seat, gate, valve stem, valve cover, stuffing box, packing gland, stem nut, hand wheel and other components. Depending on the change of the relative position between the gate and the valve seat, the channel size can be changed and the channel can be cut off. In order to make the gate valve close tightly, the mating surface of the gate plate and the valve seat are ground.
