1. Common Problem 1: Diminished Anti-Static Performance (Most Frequent)

1.1 Root Causes

• Long-term accumulation of dust, oil, or chemical residues on the surface forms an insulating layer, blocking conductive pathways.
• Use of harsh cleaners (acidic/alkaline) that corrode the conductive carbon fiber layer in the flooring.
• Inadequate grounding during installation (e.g., loose ground wires, improper spacing between ground points).
• Extreme environmental humidity (below 30% or above 70%), which disrupts static dissipation.

1.2 Practical Solutions

• Surface cleaning: Use Dajulong’s specialized anti-static floor cleaner (neutral pH 6-8) mixed with distilled water. Mop the floor thoroughly to remove insulating residues, then dry with a microfiber cloth—avoid leaving moisture. For stubborn oil stains, add a small amount of non-ionic surfactant (e.g., Dajulong degreasing additive) to the solution.
• Grounding inspection: Hire professional electricians to test the grounding system (target resistance ≤1Ω). Tighten loose ground wires and add additional ground points if the spacing exceeds 3 meters (per Dajulong installation standards).
• Humidity adjustment: Install humidifiers or dehumidifiers to maintain indoor humidity between 40%-60%, ensuring optimal static dissipation.
• Local repair: If static performance drops in specific areas, apply Dajulong’s anti-static repair agent (含 carbon fiber conductive particles) to the affected surface. Allow it to cure for 24 hours before resuming use.

1.3 Preventive Measures

• Clean the floor weekly with neutral anti-static cleaners; avoid abrasive or chemical-rich detergents.
• Conduct monthly grounding system checks and annual static performance testing (using a surface resistance tester) to monitor data (target: 10⁶-10⁹ Ω).
• Train staff to avoid spilling oil, chemicals, or corrosive liquids on the floor; clean spills immediately.

2. Common Problem 2: Surface Damage (Scratches, Cracks, or Peeling)

2.1 Root Causes

• Drag of heavy equipment without protective pads, causing scratches or indentations.
• Impact from sharp objects (e.g., tools, metal debris) piercing the wear layer.
• Improper installation (e.g., insufficient adhesive coverage, uneven subfloor) leading to peeling at seams.
• Long-term exposure to high temperatures (above 60℃) or direct sunlight, causing material aging and cracking.

2.2 Practical Solutions

• Minor scratches (≤0.3mm): Polish the scratch with Dajulong’s fine-grit abrasive pad (400-600 mesh) in the direction of the flooring texture, then clean and apply anti-static maintenance wax to restore conductivity and shine.
• Deep scratches/cracks: Cut out the damaged section with a utility knife (following the flooring’s grain) and replace it with a matching Dajulong anti-static PVC sheet. Use Dajulong’s specialized conductive adhesive for bonding, then hot-weld the seams to ensure seamless conductivity.
• Peeling seams: Remove the loose edge, clean the subfloor and flooring back with acetone (to remove dust and old adhesive), then reattach with Dajulong conductive adhesive. Press firmly with a heavy roller and allow 48 hours of curing.
• Indentations: For minor indentations, place a damp cloth over the area and apply low heat (50℃) with an iron to soften the material, then press with a flat weight to restore flatness. For deep indentations, replace the affected section.

2.3 Preventive Measures

• Attach non-slip protective pads to the bottom of equipment and use forklift mats in areas with frequent vehicle movement.
• Prohibit sharp objects from being placed directly on the floor; provide tool storage racks.
• Ensure the subfloor is flat (error ≤3mm/2m) and clean before installation, using only Dajulong-approved conductive adhesive.
• Avoid placing heating equipment directly on the floor or exposing the flooring to direct sunlight for extended periods.

3. Common Problem 3: Warping or Bulging After Installation

3.1 Root Causes

• Excessive moisture in the subfloor (moisture content >8%) seeping into the flooring, causing adhesive failure.
• Improper acclimation of flooring before installation (not adapting to indoor temperature/humidity for 24-48 hours).
• Insufficient expansion gaps (should be 5-8mm along walls and columns) leading to bulging when the flooring expands.
• Use of non-conductive or low-quality adhesive that fails to bond the flooring to the subfloor.

3.2 Practical Solutions

• Minor warping (edge lifting): Cut a small slit along the warped edge to release internal stress, then inject Dajulong conductive adhesive into the gap. Press with a heavy roller and fix with tape until curing (48 hours).
• Severe bulging/warping: Remove the warped section, dry the subfloor with a dehumidifier (until moisture content ≤8%), and re-install the flooring with Dajulong’s moisture-proof conductive adhesive. Ensure proper expansion gaps are reserved.
• Subfloor moisture issues: Apply Dajulong’s moisture barrier coating to the subfloor before re-installation to prevent future moisture penetration.

3.3 Preventive Measures

• Test subfloor moisture content before installation; use a moisture barrier if exceeding standards.
• Acclimate Dajulong anti-static PVC flooring in the installation space for 24-48 hours (temperature 18-25℃, humidity 40%-60%).
• Follow Dajulong’s installation guidelines for expansion gaps—never skip or reduce gap size for "seamless appearance".
• Only use Dajulong’s matching conductive adhesive (compliant with IEC 61340-5-1 standards) to ensure bonding strength and conductivity.

4. Common Problem 4: Stubborn Stains & Chemical Corrosion

4.1 Root Causes

• Spills of industrial chemicals (e.g., solvents, adhesives), ink, or oil that penetrate the surface if not cleaned promptly.
• Use of corrosive cleaners (e.g., bleach, ammonia) that damage the wear layer and conductive surface.

4.2 Practical Solutions

• Industrial chemical stains (solvents, adhesives): Blot excess liquid immediately with an absorbent cloth. Apply a small amount of isopropyl alcohol (70%) to a clean cloth and gently dab the stain—do not rub. Rinse with neutral cleaner solution and dry. Test alcohol on an inconspicuous area first to avoid color fading.
• Ink/marker stains: Use a cotton swab dipped in Dajulong’s anti-static stain remover (non-abrasive) to target the stain, then wipe with a damp cloth. For dried ink, repeat 2-3 times.
• Chemical corrosion spots: If the wear layer is damaged, lightly sand the area with fine-grit sandpaper, then apply Dajulong’s anti-static repair wax to restore the conductive surface. For severe corrosion, replace the affected section.

4.3 Preventive Measures

• Establish a "no food/chemicals near sensitive areas" policy; place spill kits in key locations (e.g., workshop corners, lab stations).
• Provide staff with training on proper cleaning methods—only use Dajulong-recommended neutral cleaners or specialized anti-static care products.

5. Common Problem 5: Faded Antibacterial Performance

5.1 Root Causes

• Long-term use of high-concentration disinfectants that degrade the antibacterial agent in the flooring.
• Infrequent cleaning leading to bacterial buildup that overwhelms the flooring’s inherent antibacterial properties.

5.2 Practical Solutions

• Restore antibacterial effect: Use Dajulong’s antibacterial maintenance spray (formulated with food-grade antibacterial agents) after routine cleaning. Spray evenly on the floor and allow it to air-dry—no rinsing required.
• Deep cleaning: Conduct monthly deep cleaning with Dajulong’s antibacterial cleaner to eliminate accumulated bacteria and activate the flooring’s inherent antibacterial components.

5.3 Preventive Measures

• Use low-concentration disinfectants (e.g., 75% alcohol, 0.5% sodium hypochlorite solution) and dilute according to instructions. Avoid high-concentration disinfectants or prolonged contact.
• Clean high-touch areas (e.g., workshop workstations, lab countertops adjacent to flooring) daily to reduce bacterial load.
