Epoxy floor damage is a common problem in factories, especially in the workshop ground with heavy vehicles and forklifts. No matter what kind of ground it will encounter in long term use. It is necessary to master the repair technology of small area, prolong the use time and save the cost of comprehensive renovation. Epoxy flooring is a kind of floor with excellent decoration and function. However, due to some reasons such as use, maintenance, construction, service life and so on, the epoxy flooring will be damaged. The common causes of Dongsheng flooring damage are as follows:
1. The pits, damages, scratches and traces of wheel rolling caused by customer's lack of knowledge of floor use.
2. Interlayer peeling, empty drum caused by poor base, cracking caused by tension of expansion joint of building structure, and water heave caused by improper waterproofing, etc.
3, chemical damage caused by corrosion, mainly yellow, black, all kinds of stubborn stains and so on.
4. The powdering and shedding caused by ultraviolet irradiation.
5. Defects of construction personnel or raw materials, such as pits, pink particles, sweat stains, air dust pollution, flying insects and reptiles.
If the damaged epoxy floor is to be repaired, the epoxy layer should be polished first, and then the hardened floor should be constructed on it, so that the hardness and strength of the original ground can be improved. The service life of the epoxy floor after the repair of the floor will not only be prolonged, but also the wear resistance will be improved. Where is the epoxy floor damaged? How should we repair it?
Construction process of reconstruction of damaged epoxy floor: epoxy milling-repairing-cleaning-polymer repairing material construction-maintenance-grinding
There are four ways to repair.
1. spray repair method
Advantages: Spraying repair has the advantage that other methods can not be compared. After repairing, the traces are smaller, the beauty is better and the information is saved.
Defects: the construction is difficult, the demand for construction personnel is high, and the demand is professional spraying equipment.
2. point supplement
Point repair is the most commonly used method at this stage, and most of the constructors choose this method to repair the damaged epoxy floor.
Advantages: the construction process is simple and easy to grasp, and the raw material consumption is small.
Defect: repair marks are significant, not beautiful and highly poor.
3. total concealment method
Strengths: beautiful and beautiful.
Defects: the cost is high, and it is only suitable for small space corrosive areas.
The construction procedure is similar to that of epoxy resin.
4. FRP construction method, etc.
Scope of application: long section of cracks in building structure.
1. bottom disposal: now open the V shaped openings on the cracks and use the vacuum cleaner to remove the floating dust.
2. primer construction
3. repair construction
4. epoxy putty construction.
The repaired ground has the following advantages: 1. Firm bonding without falling off; 2. High strength and good wear resistance; 3. Flat and beautiful; 4. It can be used as the final surface layer, and also can continue the construction of the rear floor.
Note: when the film thickness is not very thick, as long as the paint is of the same nature, it can be applied. It is suggested that a small piece of floor paint should be selected for repairing test, and after the paint surface is dry, see if there are cracks, wrinkles and other paint defects. If not, then it can be repaired and will not crack. Before repairing, the damaged floor paint should be carefully handled. There should be a smooth transition between the damaged and intact areas, so that the repaired area can be complete.
