The development of waterproof materials can be described as many items today. Flexible waterproof materials are classified in the form of their attached waterproof base layers, which can be roughly divided into two categories: waterproof materials for coils and waterproof materials for paints.
When the ancient poet Du Fu described the roof as leaking, he lamented that “the long night was sticky and wet, and he was fullâ€. It can be seen that the water leaking on the roof caused difficulties to the people. Then he also had “the millions of people in Andorra. The beautiful imagination of the poets has now become a reality. However, the wind and rain are still puzzling with the builders of millions of people. The development of waterproof materials can be described as many items today. Flexible waterproof materials are classified in the form of their attached waterproof base layers, which can be roughly divided into two categories: waterproof materials for coils and waterproof materials for paints.
However, the waterproof material is converted into a waterproof layer, and one of the key links is the construction—the secondary processing of the waterproof material. What are the characteristics of membrane waterproofing and coating waterproofing? Here's an explanation of how to choose the waterproof material and waterproof construction problems. The earliest traditional waterproofing membranes should be considered as paper linoleum. When using linoleum as the waterproof layer, the construction asphalt must be used for bonding. The method is three oil two felts or four oil three felts. Because of the above-mentioned practice, the construction technique is difficult to hold because of the labor intensity of the above methods. When the asphalt is prepared, a large amount of exhaust gas generates serious pollution to the environment, and the construction cannot be performed in a place where the fire cannot be used. The fire and scald accidents are easy. Occurrence of secondary maintenance of the roof is difficult. For various reasons mentioned above, Lek said that the felt waterproof layer is basically eliminated.
The new generation of waterproof materials is stepping toward lighter weight, easier construction, no environmental pollution, durability and color aesthetics. Therefore, waterproofing membranes are made from paper felt-rubber membranes-laminating modified bituminous membranes. - A variety of synthetic polymer waterproof membranes; coating waterproof material from the modified emulsified asphalt - plastic ointment - polyurethane waterproof coating - to the development of environmentally friendly synthetic polymer color waterproof coating. The development of waterproof material can be said to be a wide variety of products currently available. In a word, all kinds of waterproof materials come out and have their own advantages. They are easy to produce, or cost-effective, or durable but not waterproof. Different; Waterproof material selection factors In addition to cost, climate, geographical, architectural functions, environmental protection and many other reasons, the construction of the building is an important factor; if the place suitable for waterproofing membrane is not suitable for waterproofing with paint, suitable for coating place Not necessarily suitable for coils.
The following occasions are not suitable for the use of waterproofing of coils: wet base, poorly drained or perennially watered areas, uneven bases and many prominent embedment parts, waterproofing of backwaters, waterproofing of water tanks, large and many typhoons for many years The following areas are not suitable for coating waterproofing: wooden structure slope tile floor waterproofing, etc. Advantages of coil waterproof, such as: convenient construction, short construction period, no maintenance after forming, not affected by temperature, environmental pollution, layer thickness easy to press The fortification meter requires support, accurate calculation of materials, convenient on-site management of the construction, and is not easy to be cut through the work, the thickness of the layer is uniform, and the stress of the grassroots layer can be overcome effectively when the empty store is used (when the large-scale cracks occur at the grass-roots level, the whole waterproof layer can be maintained).
The disadvantages of coil waterproofing are as follows: When the waterproofing membrane is subjected to sizing according to the shape of the waterproof base layer in the waterproof construction, multiple layers of splicing are required for the complexly shaped base layer, and the bonding difficulty of the lap joints between the waterproofing membranes is more difficult. Large, due to the effect of multiple splicing on the aesthetics of the waterproof layer; then completely absolute sealing will become a major problem. The greatest potential for water leakage and the most chance is the overlap of the coiled materials. Then the high-grade waterproofing membrane has several decades. Durable durability, but at present there are few matching adhesives in the country, because the environment and the bonding material itself and other factors tend to lose the bonding function in advance, and the resulting waterproof failure will be self-evident; The protection of waterproof membranes after construction and maintenance after water leakage are also difficult problems. It is very important for the prevention of external mechanical damage to the exposed waterproof layer. The adhesion of waterproof membranes to the grass-roots layer is not only full-filled, but also paving and strips. Shop, empty shop, between the membrane and the base will be a water layer, regardless of the penetration of any part, degumming, leakage (even if there is only one), the entire level of the waterproof function Will lose all bad, if you can not find damaged and defective parts, the local repair is not possible, then only redo waterproof layer. For those waterproof layers with a concrete protective layer, although external mechanical penetration is no longer possible, it is not suitable for protective layers such as along trenches, and the possibility of long-term accumulation of water along the ditch and other parts due to clogging of sewers Larger sex, in which the watertightness of the waterproof layer must not have the slightest flaw; therefore, the chance of success in waterproofing the membrane along the ditch is less; along the ditch, due to the complex shape, the sealing of the water hole, the outlet and other parts is more difficult to seal. Water repellency has also become the key to the technology; due to the aggregation of living and production wastewater along the ditch, the harmful components therein accelerate the decomposition, aging, and even failure of the coil adhesive material.
In summary, the disadvantages of coil waterproofing are not equal to its incurable disease. We have proposed it and faced it to find a solution to the problem; for example, to obtain a high-quality and durable adhesive to solve the bond strength and stickiness. Problem-solving materials, meticulous construction of patience to overcome the problem of adhesive seals, use multi-channel fortification and compounding with the waterproof layer of paint to solve the problem of fear of perforation of the coil and the reliability of the waterproof layer; and then weigh the pros and cons It is not suitable for the use of coils. It should be replaced with bold waterproofing. Waterproofing of paints and waterproofing of paints. Because of its convenient construction, many manufacturers, easy access to materials, and relatively simple production equipment for waterproof paints, it is also a waterproof material for early development. And it has been used consistently. Waterproof coating can be formed as a whole without seams and seals completely. It is completely waterproof and can completely block air and water. It can completely isolate external rainwater, moisture, and all harmful gases against the waterproof base. Waterproof coating technology is easy to hold. The construction equipment is simple and can be made into continuous waterproof layer without any restriction of the complex shape of the base layer. Most waterproof paints also penetrate into the base layer and close the pores to reinforce the building. Some waterproof coatings can also be used as coils. Adhesives play a dual role of waterproof adhesion; but waterproof paint to achieve the above effect, it must be the quality of the material and the thickness of the waterproof layer as a guarantee; the current development of polymer colored waterproof coating can also be used as a variety of waterproof layer The surface decoration, its color is indiscriminate, and at the same time when it is old and wants to change the color, it covers one to two channels (within no more than half a kilogram) to become a new decorative surface, and at the same time, the thickness of the waterproof layer is increased. The polymer waterproof emulsion type waterproof coating currently available on the market is an environmentally friendly waterproof material. It uses water as the solvent and is not flammable. Poison, the waterproof coating production, construction, transportation are very safe.
Another advantage of paint waterproofing is that different thicknesses can be constructed according to the requirements of the different layers of the basement and the structural stress conditions. In other words, the thick place is thick, and the place where it does not need to be thick is thin, so that the waterproof material can be used economically.
The surface of the paint waterproof layer is smooth and clean, and the surface is easy to clean. Some high-strength paint waterproof layers (such as cement-based JS waterproof layer) can be directly applied to the human roof and the ground; the paint waterproof layer has 100% adhesion surface with the base layer ( Cracks, joints, and other parts using the evacuation method except for the empty shop site) Most are not afraid of wearing sharp objects, and some have self-healing functions, such as pvc cement, ointment, asphalt waterproof coating, etc.) Paint waterproof layer in the useful life Leakage in water is mostly because the cracking width of the base layer exceeds the extendable range of the waterproof coating. The cause of water leakage and the site where the water leakage is formed are easily found. Its warranty is very convenient, as long as a small amount of waterproof material can repair cracks and damaged parts; it is not necessary to redo. Waterproof layer. High-quality waterproof paint can be successfully waterproofed on the back surface, which is unmatched by the waterproofing of coils.
Part of the waterproof coating can be applied on the wet base layer to form a waterproof layer. This is not necessary for basements, sewers, toilets and bathrooms, and other waterproof bases that are urgent and impossible to dry, because any coil is Must be attached to a dry substrate. In a sense, the coating waterproof layer is only a coating material. Only after it is painted on the substrate, can a waterproof layer be formed after consolidation by a proportional physical and chemical reaction of the coating itself; some waterproof coatings are cured. In the process, the release of harmful gases is harmful to the human body. Some waterproof coatings need to be painted several times to complete a waterproof layer. Each brushing must have a certain interval, so the final completion of the waterproof layer takes a long time ( For several days, many adverse effects will be encountered in the curing process, such as sudden rain, tight schedule, freezing, and the environment is difficult to cure without ventilating. Some waterproof materials require hot-melt construction, while others are not allowed to be used. Open fire and so on.
In the process of construction of waterproof coating, on-site management is very important. Waterproofing of paint is relatively easy to obtain, and the production equipment of some waterproof materials is relatively simple. The packaging and deployment may be sloppy. Therefore, the situation of management negligence is caused by cutting corners and shoddy. The thickness of the organic waterproof layer will be the key to the waterproof effect and durability. However, the thickness of the waterproof layer is not as intuitive, uniform and controllable as the coil. Its thickness is based on the coating time during construction. When the number is determined, the solid content of the coating itself is the factor of the film thickness in addition to the number of coating passes. Cold-cured waterproof coatings generally do not contain solvents with a high solids content, and can reach a single thickness. Solvent-based waterproof coatings need to be cured after solvent evaporation. To reach the design thickness, multiple brushings are often required, and the lower layer is not Do not paint after drying.
In summary, both coil waterproof and paint waterproof have their advantages and disadvantages. If they are selected and matched properly, they can be used for strengths and weaknesses, complement each other, and achieve the best waterproof effect with re-economic investment. If blind use is adopted, then the injury and injury of people and workers are counter-productive.
