PTFE-coated fiberglass fabric-a oil stain leh dust nena inzawm anti-sticking leh easy-cleaning property te evaluation method te chu engte nge ni?

1. Contact Angle leh lei chunglam chakna test (Wettability Basics) .

 

- Static Contact Angle: Tui leh diiodomethane (or hexadecane) a hrana hmanga teh a ni. Tui contact angle hi a tlangpuiin 110° aia sang a ni. Oil contact angle sang zawk chuan oil fouling leh adhesion laka a do chak zawk tih a tilang.

- Rolling/Sliding Angle: Volume bik pakhata droplet chu zawi zawiin a tilt atanga a tlan chhuah tanna angle. Rolling angle te zawk hian anti-sticking tha zawk leh tihfai awlsam zawk a lantir a, hei hi oil stain testing atan a pawimawh hle.

- Surface Free Energy Calculation:Polar leh dispersive component te hi Owens-Wendt ang chi hmanga chhut a ni. Surface energy a hniam poh leh (PTFE ideal value chu 18–20 mN/m vel a ni) solid contaminants leh liquid te chu a hnim leh darh a harsa zawk thin.

 

2. Anti-Sticking Properties (Peel Force/Adhesion Force) te chu Mechanical hmanga endik a ni.

 

- Standard Pressure-Sensitive Tape Peel Test: Standard tape tarlan (eg, 3M 810 emaw pressure-sensitive tape ruat) chu PTFE tape chung lamah standard roller hmangin press a ni. Hun bituk chhunga ding tura dah a nih hnuah tensile testing machine hmangin 180° peel test neih a ni (GB/T 2792 en rawh). Peel force a hniam chuan anti-sticking property a chak zawk a, ideal value chu 0.1 N/25 mm hnuai lam a ni.

- Specific Medium Adhesion Test: Adhesive substance hman tak tak, asphalt, self-adhesive label, emaw hot-melt adhesives te chu a chung atanga paih chhuah theihna tura chakna mamawh tehna atan hman a ni.

 

3. Oil Resistance leh Tifai awlsamna Simulated Test

 

- Oil Stains Sliding/Residue Method: Engine oil, cooking oil, emaw artificial grease emaw zat bituk chu sample pakhat angle engemaw zat tilt-a dah a ni. Oil stain sliding length emaw, a chunglama residual area percentage emaw chu an teh thin.

- Quantitative Wiping tihfai thatna: 1.1.

    - Standard artificial soil (carbon black, grease, leh oleic acid inzawmkhawm) chu a rualin hnawih a, a vawt thin. Lint-free cloth tui leh neutral detergent hmanga hnim chu set load hnuaiah cycle engemaw zat chhung chu a hnung leh hnung lamah phihfai nan hman a ni.

    - Jiangsu-a PTFE-coated fiberglass fabric siamtute chuan an phih hma leh an phih hnua rawng danglamna ΔE tehna atan, emaw, leilung mass la awm (gravimetric method) hmanga tihfai efficiency tehna atan color difference meter an hmang tlangpui. ΔE tlem zawk leh residual weight hniam zawk hian easy-cleaning performance tha zawk a tilang a ni. A tihfai tawhna hmuna contact angle recovery rate pawh teh theih a ni bawk.

- Quick Qualitative Test with Oily Marker: Oily marker hmang hian a chung lamah line siam a ni. Ink chu a hring hring (discontinuous droplets)-ah a tlahniam emaw, a darh chhunzawm zel emaw tih enfiah la, chutah chuan puan vawt hmangin phihfai la, awlsam taka lakchhuah theih a nih leh nih loh en rawh. Shrinkage langsar tak leh lakchhuah awlsamna hian anti-fouling tha tak leh tihfai awlsamna property tha tak a nei tih a tilang.

 

4. Anti-Dust leh Anti-Particle Adhesion Testing neih a ni

 

- Dust Settling Method: Standard test dust (eg, ISO 12103-1 A2 fine dust) chu closed chamber chhunga vertically emaw 45°-inclined sample surface-ah natural takin a settle phalsak a ni. Gentle tapping emaw low-pressure gas hmanga blowing emaw hnuah residual dust area/mass chu image analysis emaw gravimetric method hmangin an teh thin.

- Airflow Method hmanga Dust Removal: Leivut awm zat hriat tawh chu horizontal sample-ah inang tlang taka theh a ni. Nitrogen stream pakhat flow rate chu a tisang zauh zauh a, leivut chu a puak vek theih nan airflow velocity tlem ber mamawh chu record a ni. Velocity a hniam poh leh anti-dust adhesion property a tha zawk.

- Electrostatic Adsorption Effects Evaluation: Dust adsorption hi static electricity hian a tizual fo thin avangin, surface resistivity leh electrostatic decay time pawh test a ngai a, chu effect chu chemical anti-sticking emaw electrostatic adsorption vang emaw a nih leh nih loh hriat theih a ni.

 

5. Durability Evaluation thlawptu

 

- High-temperature aging (eg, 260°C emaw 300°C-a) emaw friction/wear (Taber abrasion) hnuah, a chunga kan sawi tak contact angle, peel force, leh cleaning efficiency test te hi hun rei tak hman chhunga performance a tlahniam nasa loh nan tih nawn leh a ni.
