T/JAMIA 002-2024 Negative ion solar film

Scope

Main technical content: - Appearance requirements: The negative ion solar film should have a smooth surface without creases, tears, particles, bubbles, pinholes, or foreign impurities, and its edges should be intact and undamaged. The specific appearance requirements of the film surface are shown in Table 1. - Table 1: Appearance quality - Defect type - Defect size requirements - A: Point-like defects - Diameter < 0.3 mm: Not allowed - 0.3 mm ≤ diameter < 0.5 mm: Not allowed - Dense presence - 0.5 mm ≤ diameter < 1.0 mm: ≤2.0 × Sc, per 1.0 mm - 1.0 mm ≤ diameter < 1.5 mm: ≤1.0 × S, per 1.0 mm - Diameter ≥ 1.5 mm: Not allowed - B: Linear defects - Width < 0.1 mm: Not allowed - 0.1 mm ≤ width ≤ 0.3 mm: Scratches with a distance ≥ 100 mm and length ≤ 30 mm, ≤1.0 × S, per unit - Width > 0.3 mm or length > 30 mm: Not allowed - C: Wrinkles: Visible to the naked eye, not allowed - D: Bubbles: Visible to the naked eye, not allowed - Point-like defects refer to visible spots, crystals, impurities, pits, foreign objects, or concavities on the tinted film. - Dense presence refers to the presence of more than three point-like defects within a 200 mm diameter circle. - S is the film area in square meters, with two decimal places retained. - Linear defects refer to indentations or flow marks. - The thickness of the negative ion solar film should be 4.0 mil, with a permissible deviation of ±10%. - The formaldehyde absorption of the negative ion solar film should be less than or equal to 0.1 mg/m3. - The antibacterial performance of the negative ion solar film should comply with Table 2. - Table 2: Antibacterial performance - Mold resistance grade: 0 level - Note 1: Rating standard: 0 level — no mold growth; 1 level — mold growth area < 10%; 2 level — mold growth coverage 10%–30%; 3 level — mold growth coverage 30%–60%; 4 level — mold growth coverage > 60%. - Not
