Micrometer Film Applicator QPI‑MAFA Series – Käyttötarkoitus:
ASTM Test Method (ASTM D823 – Standard Practices for Producing Films of Uniform Thickness of Paint, Varnish, and Related Products)
Tarkoitus
The ASTM D823 procedure defines how to produce uniform wet films of coatings for laboratory evaluation. It ensures repeatable film thickness and surface quality for tests such as gloss, adhesion, hardness, and drying time.
Laite
Micrometer Film Applicator (QPI‑MAFA Series) — precision stainless‑steel applicator with analog or digital micrometer heads for adjustable gap control.
Test substrate — glass, metal, or sealed paper panels cleaned and prepared according to coating type.
Drawdown surface — level, vibration‑free bench or automatic film applicator platform.
Menettely
Valmistelu
Mix coating thoroughly and condition to test temperature (typically 23 ± 2 °C).
Clean substrate with solvent or lint‑free cloth.
Gap Adjustment
Set micrometer heads to the desired film thickness (e.g., 50 µm, 100 µm, 150 µm).
Verify parallel alignment of the blade using calibration blocks.
Elokuvasovellus
Deposit a measured amount of coating in front of the blade.
Draw the applicator smoothly across the substrate at a constant speed (150–300 mm/s).
Avoid vibration or jerking motion.
Drying and Evaluation
Allow the film to level and dry under controlled conditions.
Measure wet and dry film thickness using a calibrated gauge.
Key Parameters
Film uniformity tolerance: ± 2 µm for gaps ≤ 100 µm.
Toistettavuus: within 1 % of target thickness.
Surface finish: free of streaks, bubbles, or edge lift.
Engineering Insight
The ASTM method emphasizes mechanical precision ja repeatable drawdown speed. The QPI‑MAFA’s micrometer control allows engineers to reproduce identical coating thicknesses across multiple samples, ensuring reliable comparative data for formulation studies.
ISO Test Method (ISO 2808 – Paints and Varnishes: Determination of Film Thickness)
Tarkoitus
ISO 2808 specifies standardized techniques for measuring and controlling film thickness of paints, varnishes, and related coatings. When used with a micrometer film applicator, it defines how to achieve and verify uniform wet films for laboratory testing.
Laite
Micrometer Film Applicator QPI‑MAFA Series — adjustable doctor‑blade applicator with precision micrometer heads.
Reference substrate — glass or metal panels conforming to ISO 1514.
Thickness measurement tools — wet‑film combs or electronic gauges calibrated per ISO 2178 or ISO 2360.
Menettely
Kalibrointi
Confirm micrometer gap using certified feeler gauges or calibration blocks.
Record nominal gap setting and environmental conditions.
Elokuvasovellus
Apply coating evenly across the substrate using the QPI‑MAFA applicator at a controlled speed.
Maintain constant pressure and angle to ensure uniform flow.
Thickness Verification
Immediately measure wet film thickness at multiple points.
After drying, measure dry film thickness and compare to theoretical values.
Reporting
Document gap setting, coating type, viscosity, substrate, ambient temperature, and humidity.
Calculate deviation between nominal and measured thickness.
Key Parameters
Measurement accuracy: ± 5 % of nominal thickness.
Environmental control: 23 ± 2 °C, relative humidity 50 ± 5 %.
Surface uniformity: no visible streaks or discontinuities.
Engineering Insight
The ISO method focuses on traceability and calibration. It ensures that every film produced with the QPI‑MAFA applicator can be correlated to certified measurement standards, supporting international quality assurance and cross‑laboratory reproducibility.
