Epoxy wear-resistant flooring is an important category in epoxy floor coatings. To ensure its performance, construction quality must be guaranteed. What are the precautions in the construction process? Experts from the China Epoxy Resin Industry Association said that there are 4 key points in the construction of epoxy wear resistant flooring.
First, the material that is transported to the construction site in the construction environment must be placed in a place where wind, rain, and direct sunlight can be avoided. If the sun shines directly on the construction surface, air ions contained in the coating film in the base layer or not yet fully hardened may cause small air holes due to poor discharge, so cover the entire window with a newspaper or a plastic cloth. In order to prevent the wind from blowing dust from the outside and contaminating the construction surface, the doors, windows, gaps, etc., should be sealed with tape when the film is completely hardened during construction. At the same time, it is necessary to prevent the wind blown by the gaps from entering the dust. Attention should not be given to the construction below 5°C. If possible, heating or air conditioning may be turned on. When the rain is over, the open sections are closed to prevent the moisture from affecting the construction surface. Obstruct ventilation.
The requirements for safety and health management are also important. Persons engaged in construction must receive special training to obtain employment certificates and have certain knowledge of chemical products; they must wear overalls, work shoes, and labor-proof products during construction; various materials inadvertently stick to the skin and sometimes damage the skin. The soap is clean and seriously sent to the hospital for treatment; all materials are not allowed to touch any water (except water-based epoxy coating), construction workers must bring towels to perspiration to prevent sweat from falling into the ground or materials during construction; Epoxy materials contain traces of combustibles. Fireworks are strictly prohibited on the construction site. Materials on site are not allowed to be placed in places exposed to direct sunlight. Construction tools need to be inspected periodically. Special personnel are to be maintained and kept clean. The construction site should be clearly marked and strictly prohibited. People enter.
With regard to the quality management regulations, experts from the China Epoxy Resin Industry Association emphasized that before construction, construction technicians should confirm the following items: base area and base surface status, select materials and construction structures, and be familiar with material specifications, proportions, and amounts; after construction Construction technicians should confirm whether there are any obvious flaws, pores, particles, orange peels, etc., whether there is color unevenness and other coating defects, whether the color is the same as the sample, whether there is color difference, and whether the coating film is hardened according to normal rules. (Using nails to make simple judgments); construction personnel should strictly follow the public execution of each step of the construction and find that there are exceptions that should be identified and recorded to prevent recurrence. If they cannot be resolved, they should immediately report to the technical personnel.
In addition to the above-mentioned several types of phenomena to be noted, other changes in the use of the film should also be given enough attention: the place where the color change is particularly severe in the sun is liable to yellowing; wear often occurs when people, goods, etc. pass through; scraping Traces of wounds that have been accidentally hit by sharp objects (repairable, but traceable), scratches should be promptly repaired, otherwise it will affect the adhesion of the coating around it; softening often has a base surface with open water, or impregnation with chemical solvents Occurrence of surface conditions. In addition, experts from the China Epoxy Resin Industry Association believe that when construction is completed and the site is handed over to customers, customers should be reminded of the maintenance and maintenance methods of epoxy floor coatings in order to maintain good quality on the ground, including: ) Daily cleaning can be used soft Broom or rag cleaning; serious dirt when using a neutral detergent, washed with a rag, and then washed with water, fully dry a thin layer of wax; ground spilled acid, alkali and other chemicals should be promptly washed with water, if it is seasoning The oil, etc., can be wiped with a rag; the smooth coating can be regularly maintained with a bright wax for a long time.
