Problems solved by technology

[0003] Most waterproof projects in my country use traditional waterproof materials, which have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature.
At the same time, there are still the following problems: (1) Traditional waterproof coatings are not environmentally friendly, corrosive, have large shrinkage of their own materials, and poor puncture resistance; (2) Traditional waterproof coatings are less brushed, and it is difficult to detect missing brushes; (3) Traditional waterproof coatings The construction base surface has strict requirements and must meet the requirements of solidity, smoothness and drying, otherwise the quality of the project is difficult to guarantee; (4) The traditional waterproof coating process is simple, low in technical content, and easy to fake; (5) If the wall is painted with a large area of ​​waterproof coating, It is difficult to guarantee the requirements for pasting large-size decorative bricks on the facade.
[0004] Traditional waterproof coatings are used for roof waterproofing, which is easy to cause aging, cracking, deformation, breaking, and delamination; for indoor waterproofing, it is difficult to construct for places with complex shapes, and it is even more difficult to guarantee the quality of leakage. It takes a lot of money and labor to repair every few years, which not only disrupts people's normal life, work and production order, but also affects the service life of the entire building.
