Epoxy self-leveling detection method
Epoxy floor design is a crucial part. Poor design can cause problems. Reasonable design can avoid problems. People often do not pay enough attention to the design of the epoxy resin industrial floor. Usually they are listed in the “internal decoration†item in the new engineering type technical requirements and engineering type budget books, almost always waiting for the entire structure or concrete slabs. The problem began to be considered after the completion of the pouring, and in the transformation into the project and the maintenance project, the floor plan was often considered after the installation of the equipment or the trial operation of the factory. This concept may be related to infrastructure investment, but it is worth paying attention to if it is conceived to cause losses due to production problems caused by underestimation of ground design.
The basic design basis is: the end user's use requirements, expected or actual site conditions, new construction or repair and maintenance works.
Construction period
An important goal for users in any project is to shorten the engineering cycle. Whether it is a new construction or a renovation project, the economic requirements are to start production as soon as possible. This means that in the early stages of the project there is a need to distinguish clearly the project cycle and the feasible construction time. Experts from the China Epoxy Resin Industry Association believe that only floor systems that meet the following requirements may be considered: Coatings can be applied directly on fresh or aged cement floors; the entire system can be quickly constructed with each coating interval The time is short; the surface layer cures fast and can withstand traffic in a short time. The advanced epoxy floor technology can prevent the damage of the coating caused by the wet base surface. When the active resin material is applied on the surface of the cement-based substrate, the moisture content of the substrate must not exceed 6%. Otherwise it will damage the coating. The initial small bubble will appear within a very short time after construction and will gradually develop and expand. Finally, the coating will be completely peeled off. This kind of damage, called "permeation blistering", must be avoided.
control risk
In order to ensure that the selected products can be truly constructed according to the requirements of the branches, and in order to achieve the required performance requirements, experts from the China Epoxy Resin Industry Association stated that the ideal epoxy resin floor system project should be: The diagnosis of the project is performed during the construction process and the completed floor is evaluated.
1, design life. This may be the most basic index, and it is the first question to ask when choosing a floor. What is the design life of the plant: 2 years, 5 years, 10 years, 20 years? Is regular maintenance feasible or necessary? The choice of ground plan must meet the expected design life or desired maintenance-free period.
2, the use of requirements. Static and dynamic loads imposed on the ground during construction, production, renovation and maintenance need to be considered. On the one hand, the epoxy floor must be able to withstand the required load, and on the other hand the coating on the substrate can only play its due role if the substrate (such as a concrete structural slab or a cement mortar facing) also meets the requirements. In some cases, overhangs need to be reinforced by sticking carbon fiber sheets.
3, construction joints. There are tiny moving seams such as construction joints, etc. In the epoxy floor system external treatment scheme, the elastic seal coating method can be used for the treatment. Structural moving joints or isolation joints present in the base concrete slab must be left on the floor. At the same time, experts also recommend setting up mobile seams at the highest point of the ramp and the perimeter of the wall and equipment.
4, the surface design. The easy-to-maintain floor, in addition to being able to seamlessly protect the concrete from corrosive liquids and mechanical wear, must also meet the requirements for hygiene, safety and durability, and provide a bright and friendly atmosphere. The design philosophy of architects and customers always requires the consideration of both functional and subjective criteria. By using special construction methods, different requirements can be satisfied at the same time.
