First, the treatment of epoxy floor surface
1. The newly completed industrial floor must go through certain conservation before it can be constructed for about 28 days.
2, remove the surface of the cement laitance, old paint and debris attached to the garbage.
3, thoroughly remove the surface of the oil, with grams of oil cleaning agent treatment.
4. Remove stagnant water and thoroughly dry the tide.
5, the surface of the need to use clean sweeper and large vacuum cleaner to complete.
6. The flat surface is allowed to have a gap of 2 to 2.5 mm, water content below 6%, and a pH of 6 to 80.
7. The roughing of the floor surface needs to be completed with a dustless grinder and thoroughly cleaned with a vacuum cleaner.
8. Apply putty to the holes and obvious depressions on the surface of the floor to fill up the scraping, and then dry it and sand it.
Second, coating closed coating
1, in the treatment of clean, flat surface, using high-pressure airless spray or roller coating, epoxy sealing primer together.
2, epoxy sealing paint has a strong permeability, when the brushing primer should be added to a certain amount of thinner, so that the diluted primer can penetrate into the base layer, to enhance the adhesion of the coating and the base layer, its coating It must be continuous and uninterrupted. The amount of coating should be exactly saturated on the surface.
3. Partial coating can be applied by brush, and the excess surface primer must be polished before the next process.
Third, the batch scraping scraper
1. Two methods of applying putty on the surface of the primer after hard drying (25°C, about 4 hours) to ensure the wear resistance, pressure resistance, collision, water, mineral oil, acid and alkali solution, etc. of the floor Performance and adjust the flatness of the ground.
2, with 100 to 200 mesh quartz sand and epoxy scraper, as the first putty, to fully stir evenly, scraping, this road is mainly used to enhance the ground's wear and compression resistance.
3. Polish the first putty with a sand bag type dustless rolling sander and vacuum clean.
4, with 200-270 purpose quartz sand and epoxy scraper, as the first putty, to fully stir evenly, scraping, this road is mainly used to enhance the wear and flatness of the ground.
5. Polish the second putty with sand bag type dustless rolling sander and vacuum clean.
6, after the two putty hard work, if pock, cracks should be repaired, and then polished with a flat sander to make it smooth, and vacuum clean.
7. The number of quartz sand uses is determined by the field engineer according to the specific conditions of the ground.
Fourth, coating the middle floor
1. Finish the middle layer with epoxy floor coating on the surface of polished and cleaned putty (20°C, 24 hours). The coating method can be applied by brush, scraping, high pressure airless spraying, large-area construction with high pressure airless spray For best results, the spray pressure is 20-25 MPa.
2, this time can make the ground more flat, easier to find the defects still exist on the ground, so that the next level construction leveling.
3, this time also facilitates Party A's arrangement of equipment installation.
V. Finishing floor surface
1. After the intermediate layer is dried, the epoxy floor coating is applied. The coating method is applied by scraping and high pressure airless spraying, but it is preferable to use high pressure airless spraying.
2. Sanding and vacuuming should be carried out on the intermediate layer with a sand bag type dustless rolling sander before painting.
3. If Party A is working hard in the middle layer, installation and commissioning of the equipment is first carried out, resulting in new defects on the ground. The application of the scraper is used to level and polish the surface, and the surface is cleaned by suction and cleaning.
Six, epoxy floor construction precautions
1. The ambient temperature at the construction site should be higher than 5°C, and the construction can only be performed when the relative humidity is less than 85%.
2. The constructors should make actual records of the construction site, time, temperature, relative humidity, floor surface treatment, and materials in preparation for the examination.
3. After the paint is applied, the related equipment and tools should be cleaned immediately.
Seventh, safety technical requirements
1. Put warning tapes and hang warning signs around the construction site.
2. It is forbidden to open fire within 10 meters around the construction site and smoking is prohibited.
3, the use of high pressure airless spray pump should be grounded.
4, paint and thinner should be placed in a well-ventilated warehouse.
5. Pay attention to personal protection during work.
6, the use of power tools must be responsible for the person in charge, cut off the power before completing the departure.
Eight, epoxy floor use and maintenance
1. After construction of the paint is completed, it shall be used rushed during the maintenance period, and ventilation equipment and fire prevention measures shall be strengthened.
2, floor use, production staff are not allowed to wear shoes with nails to walk on the top.
3. All work equipment must have a fixed special frame for placement. It is forbidden to touch the ground with objects such as sharp-angled metal parts, causing damage to the floor paint.
4. When heavy equipment such as equipment is installed in the workshop, there should be thick rubber and other software materials on the supporting points that contact the ground. It is forbidden to use iron pipes and other metals to pull the equipment on the ground.
5. When high-temperature welding and other operations are performed in the workshop, apply asbestos cloth and other refractory materials to the place where the welding spark splashes to prevent burning of the coating.
6. Once the floor is damaged, repair the paint in time to prevent the oil from penetrating into the cement through the damaged area, causing large areas of paint to fall off.
7. Do not use strong chemical solvents (xylene, banana water, etc.) when cleaning large areas of the floor in the workshop. General use of detergents, soap, water, etc., with a washing machine. In the absence of a washing machine, you can use sawn wood powder to remove it and then clean it.
8, winter construction, the ambient temperature is lower than 5 °C, can be used in winter epoxy industrial floor coating.
1. The newly completed industrial floor must go through certain conservation before it can be constructed for about 28 days.
2, remove the surface of the cement laitance, old paint and debris attached to the garbage.

Ferroalloys, generalized ferroalloys, are products that are added to molten iron as a deoxidizer, elemental additive, etc. in steelmaking to provide a characteristic or meet certain requirements. An intermediate alloy of iron and one or more elements, mainly used in steel smelting. In the steel industry, all intermediate alloys for steel making, whether iron or not (such as silicon calcium alloy), are generally referred to as "iron alloys". It is customary to include certain pure metal additives and oxide additives.
