Teflon high-temperature fabric-a delamination phenomenon chu eng nge ni?

I. Delamination Phenomenon awmzia (A awmzia) chu

1. Structural Composition tih hi a ni

Teflon high-temperature fabric hi fiberglass fabric substrate atan hmanga siam, polytetrafluoroethylene (PTFE) dispersion hmanga impregnate a, temperature sang takah sintering hmanga siam a ni.

2. Phenomenon awmzia sawifiahna

Delamination tih hian surface PTFE coating leh internal fiberglass base fabric inkara inthenna leh peeling te, emaw, coating layer tam tak inkara inthenna leh peeling te a kawk a, chutah chuan an inzawm tlat tawh lo.

II. Delamination awm dan hmuh theiha lantir

1. Blistering leh Bulging

Puan chungah hian bubble sang tak tak a lang a, press a nih chuan hollow feel a awm a—hei hi delamination chhinchhiahna hmasa ber a ni.

2. Interlayer-a Peeling tih a ni

A chunglam coating chu awlsam takin film te tak te ang maiin sheet-ah a phelh thei a, a hnuaia fiberglass dum chu a lang chhuak thei a ni.

3. Localized Whitening leh Flaking te a awm thei

Heat emaw friction emaw a awm hnuah a chunglam chu a var hmasa a, chutah chuan coating chu a cracking leh flaking in chunks a ni.

III. Delamination awm chhan ber berte

1. Thermal Stress avanga chhiatna thleng thei

Hun rei tak high-temperature-a hnathawh hian PTFE leh fiberglass inkarah hian an thermal expansion coefficient hrang hrang avang hian internal stress a siam thin. Heating leh cooling cycle chak tak hian coating chu a ti chhuak thei bawk.

2. Production Quality lama chhiatna awm thei

Fiberglass fabric surface treatment tha tawk lo, PTFE impregnation tha lo, emaw sintering tling lo emaw chuan inherently weak interfacial bonding a thlen thei.

3. Adhesive a hlawhchham

Product thenkhatah chuan PTFE film chu base fabric-ah adhesives hmanga bond a nih chuan adhesive hian temperature sang tak a tuar thei lo thei a, chu chuan direct delamination a thlen thei a ni.

4. Mechanical lama hahna (Mechanical Fatigue) a awm

Flexing nawn leh, high-tension stretching leh pawn lam thiltihtheihna dangte chuan coating leh base fabric inkar interface chu a tichhe chhunzawm zel a ni.

5. Chemical hmanga beihna

Acid chak tak tak, alkalis chak tak tak, emaw solvent te chu coating interface chhungah a lut thei a, chu chuan corrosion a thlen thei a, bonding strength a hloh thei bawk.

IV. Delamination-a direct Hazards leh Identification Method awlsam tak te

1. Non-Stick Performance hloh

Coating chu a peel off chuan fiberglass chu a lang chhuak a, materials te chu fabric chung lamah nghet takin a innghat ang a, a release function chu a hloh ang.

2. Chakna tlahniam nasa tak

Tunah chuan fiberglass hi coating hmanga venhim loh a ni tawh a, a chhe thei a, a lo chhuak thei bawk a, hei vang hian high-temperature fabric chu a chhe nghal vat thin.

3. Thil siam chhuah bawlhhlawh (Product Contamination).

Detached coating debris hian direct-in thil siam chhuah, ei tur emaw, puan emaw a ti bawlhhlawh thei a ni.

4. Identification Method awlsam tak

Blade hmangin hmun langsar lo chu lightly scratch rawh. Plastic vun ang maia coating chu awlsam taka chawi chhuah theih a nih chuan delamination a awm tih a chiang thei.
