The application in road and bridge engineering is as follows:
most of road and bridge engineering is municipal engineering, but most of road surfaces and bridge sections do not belong to underground engineering, cement-based permeable crystallization type waterproof materials are almost not used in the past, but in recent years, along with the continuous deepening of people's familiarity with products, products are gradually applied to the field, such as Beijing, Henan, Zhejiang and the like, and road and bridge engineering is applied to the construction of the materials, and the materials are mainly applied to the joint reinforcement of road surface construction joints, waterproof and anticorrosive coatings of concrete base surfaces of piers and anticorrosive and waterproof treatment of welding positions. Use as the sole material for road surfaces and bridge decks is not claimed.
The application on the building outer wall:
the waterproof coating that the building outer wall used is more, but does have many problems, must puter earlier and make level, if inhomogeneous careful, will influence the whitewash of coating, and the cracking phenomenon that shells is more, and water-proof effects also can be influenced certainly. If the construction cannot be carried out in rainy days, the whole construction period is influenced.
The application in the kitchen and bath water-proof engineering is as follows:
in the waterproof construction of buildings such as kitchens, toilets and the like, JS composite waterproof paint, polyurethane waterproof paint, modified asphalt-based waterproof paint and the like are used in a large number. With the continuous and deep familiarity of people with the capillary crystalline type sealing densification agent, people can feel and experience the advantages of the material on kitchen and toilet water-proof engineering, so far, a few of civil building kitchen and toilet engineering in various large and medium cities use the material, such as Beijing, Shanghai, Zhejiang and other places, and the kitchen and toilet water-proof engineering focuses on the reasonable treatment of a contact seam between a pre-buried pipe and a concrete base surface in the construction process, and three suggestions are provided: firstly, the pipe seam treatment is operated according to a leakage stoppage construction method, a V-shaped groove is chiseled for plugging, and then a waterproof coating is coated; secondly, a waterproof coating is also formed along the 20-30CM upward extension of the side wall so as to ensure that the waterproof coating cannot leak from the corner of the wall; and if the condition is satisfied, the top plate is also provided with a waterproof coating so as to prevent water leakage of the upper layer from dripping.
The application in roof maintenance is as follows:
the cement-based permeable crystallization type sealing densification agent is rejected to be applied to large-area roof waterproofing engineering for a long time, only one reason is that the cement-based permeable crystallization type sealing densification agent is a rigid waterproof material, once a structure is cracked, a waterproof coating loses effect, the rejection is reasonable, if deep research is conducted, people can suspect all waterproof materials because the waterproof material is used for preventing water and not used for preventing the structure from cracking, and even if the flexible waterproof material is subjected to pulling deformation, the people cannot guarantee whether the waterproof effect is still achieved, so that the cement-based permeable crystallization type sealing densification agent can be intelligently rejected to be applied to large-area roof waterproofing engineering, and other effects of the cement-based permeable crystallization type sealing densification agent in the roof engineering can also be considered.
In terms of roof waterproof engineering, three points are suggested: first, the flat of small-size building, oblique roofing all can use this type of material, conditional case, can do the color asphalt felt tile before laying, apply paint waterproof coating with a brush earlier, it is waterproof to make twice, in order to ensure to be all the same, roofing maintenance engineering can adopt this type of material, such as construction joint, the maintenance of settlement joint, the seepage of small area roof etc. it is effectual, the just examination of not hindering, three large tracts of land roof engineering is just doing, gentle, heat preservation three, when even more waterproof engineering, available cement base infiltration crystallization type waterproof material does first rigid waterproof, the design can refer to relevant plate box, the design drawing set of the firm and soft multichannel waterproof engineering of making good with others.
