Introduction
Thickness: 1.0mm, 2.0mm, 3.0mm
Floor characteristics: can eliminate and prevent static electricity or electromagnetic waves, avoiding static sparks and electromagnetic interference and damage.
Applicable scope:
1. Electronics, computer production, packaging, and computer control centers;
2. Light industrial factories, offices, warehouses, etc., requiring anti-static cooperation as floor decorative paint.
Construction workers:
1. Waterproof treatment: The ground floor must have been treated for waterproofing;
2. Base treatment: Perform grinding, repair, and dust removal according to the condition of the base;
3. Newly completed cement floors need to undergo a certain maintenance period before construction (generally about 3 weeks in summer, about 6 weeks in winter). The ground must be hard, flat, free of oil stains, with a moisture content <6%, strength >24, flatness ≤2mm/M, PH<8.
4. Epoxy sealing primer: Apply one or two coats of highly permeable and adhesive epoxy sealing primer according to the condition of the ground to enhance surface adhesion;
5. Epoxy mortar intermediate coat: Mix the paint and hardener in the correct ratio, add an appropriate amount of quartz sand according to the condition of the ground and coating requirements, stir thoroughly, pour onto the base coated with sealing primer, and directly scrape or trowel with a trowel; operations should be uniform, and seams should be even and natural.
6. Laying copper mesh: Lay a closed loop 50~100cm from the construction edge, with evenly spaced copper foil mesh laid transversely and longitudinally at intervals of 3~6 meters. Ground according to GBJ97 method. Ground resistance is less than 42.
7. Anti-static primer: Apply two coats of highly permeable and adhesive anti-static primer, ensuring even application without missed spots; corners and edges should be brushed; after the paint film is dry, determine whether to grind based on flatness. If grinding is needed, thoroughly clean the base after grinding and measure the surface resistance to be below 10*2 before proceeding to the next coat.
8. Anti-static topcoat: Apply two coats of solvent-based anti-static epoxy topcoat, with a surface resistance of 2.5x10*~ 1x10*2 after curing. The finished floor should be bright, clean, uniform in color, and free of blisters.
9. Completion of construction: Can be walked on after 24 hours, can be heavily pressed after 72 hours, and can be used after 7 days of complete curing (based on 25C, lower temperatures require appropriate extension of open time).
Construction parameters:
The ratio of epoxy sealing primer: main paint: hardener = 2:1 (weight ratio) Reference usage 0.2kg/m2 (two coats)
The ratio of epoxy mortar intermediate coat: main paint: hardener = 5:1 (weight ratio) Reference usage depends on the thickness of the paint film, and an appropriate amount of quartz sand can be added according to the condition of the ground.
The ratio of anti-static primer: main paint: hardener = 5:1 (weight ratio) Reference usage 0.2kg/m2 (two coats)
The ratio of solvent-based anti-static epoxy topcoat: main paint: hardener = 3:1 (weight ratio) Reference usage 0.2-0.3kg/m2 (two coats)
Construction conditions: It is recommended to use above 10C to avoid condensation of water vapor, requiring the construction base to be dry and clean, with relative humidity < 80%.
