The quality of epoxy floor is not only affected by material, but also by construction technology. In order to fully guarantee the construction quality of epoxy flooring, the following points must be paid attention to during the construction process: materials transported to the construction site in the construction environment must be placed where wind, rain and direct sunlight can be avoided. If the sunlight is directly exposed to the construction surface, the air ions contained in the basic layer or in the film which has not yet been completely hardened will cause small air holes due to poor discharge, so the whole window should be covered with newspapers or plastic sheets.
In order to prevent the wind from blowing dust from the outside to pollute the construction face, during the construction period when the membrane is completely hardened, the ventilation areas such as doors, windows and crevices should be sealed with protective tape. At the same time, it is necessary to prevent the wind from blowing into the crevice from bringing dust. Attention should not be paid to the construction under the environment of less than 5 C. If possible, heating or air conditioning can be turned on. When it rains, the open part should be closed to avoid dampness affecting the construction surface, but do not hinder ventilation.
Safety and health management requirements are also important. Personnel engaged in construction must be specially trained and have a certain knowledge of chemical products; during construction, they should wear work clothes, shoes and anti-labor articles; all kinds of materials accidentally touched the skin sometimes damage the skin, clean it with soap as soon as possible, and send it to hospital for treatment seriously; all kinds of materials are not allowed to touch any moisture (except environmental epoxy floor paint).
Every construction worker should wear a towel to wipe sweat to prevent sweat from dripping into the ground or materials during construction; because epoxy floor materials contain trace combustibles, fireworks are strictly prohibited at the construction site, and the materials on the site are not allowed to be placed in places directly exposed to sunlight; construction tools should be inspected regularly, and maintenance and cleanliness should be maintained by specialists; construction site should be clearly marked and no unrelated personnel should be allowed to enter. Enter.
Before construction, construction technicians should confirm the following items: base area and base surface condition, selection of materials and construction structure, familiarity with material specifications, proportioning and dosage; after construction, construction technicians should confirm whether there are obvious defects such as smear marks, air holes, granules, orange peel, whether there are color unevenness and other coating defects, and whether the color and samples are available. If there is color difference, whether the film hardens according to the normal law (simple judgement with nails); the construction personnel should strictly follow the public implementation of each step of construction, find out the reasons for the anomalies and record to prevent recurrence, and report to the technical personnel immediately if it can not be solved.
In addition to the above phenomena, other changes in the film during use should also be paid enough attention to: yellowing in areas where the discolored sunshine is particularly serious; wear often occurs when people and goods are in excess of traffic; scratches of wounds (repairable, but with traces) scratched by unexpected sharp objects should be repaired in time, otherwise the adhesion of the film around them will be affected. Softening often occurs when the surface is flowing in water or impregnated with chemical solvents.
When the construction is finished and the site is handed over to the customer, the maintenance and maintenance methods of epoxy floor coating should be reminded to the customer so as to maintain the good quality of the ground, including: daily cleaning can be done with soft broom or cloth cleaning; serious dirt can be cleaned with neutral detergent and cloth washing, then washed with water and dried to a thin layer of wax; the ground is spilled with acid, alkali and other chemicals. The product should be washed with water in time, if it is seasoning, oil, etc., wipe it with a rag; smooth coating can be maintained regularly with bright wax, and keep beautiful forever.
