Fabric siamnaah PTFE Coating Thickness dik taka control

PTFE high-temperature fabric siamtu professional source a nih angin, Jiangsu Aokai New Materials hian chipchiar takin a sawifiah che a ni. Glass fiber fabrics (or similar fiber felts/textiles) PTFE emulsion hmanga impregnate dan tur atan chuan thickness control principle hi dip-coating method pangngai nen a inang a ni. Harsatna ber chu fiber substrate-te porous leh uneven structure-ah a ni. Chuvangin, thickness control bulpui ber chu micro liquid absorption capacity leh macroscopic process parameters te chu precision sang tak nena balance a ni.

1. Emulsion Formula: Coating layer tin base thickness a teh thin

Solid content leh viscosity : Solid content hniam dispersion (eg 45%) adopt la, pass khatah coating thinner siam la, drying cracking hlauhawmna a ti tlem bawk. Emulsion viscosity hi fluidity leh coating pickup amount siamthatna atana pawimawh ber a ni.

2. Impregnation Process: Mechanical balance chak tak a ni

Lifting / Squeezing speed : Speed ​​hian gravity leh viscous force balance avanga wet film thickness lo awm tur a rel a ni. Speed ​​sang zawk chuan emulsion tam zawk a phur a, wet film thick zawk a siam bawk.

Impregnation hun leh fiber pretreatment : Fiber te chu a hnim vek tur a ni a, a luh theih nan. Impregnation hmain fiber chunglama burr leh bawlhhlawh awmte chu uluk taka tihfai a ngai a, chutiang chuan uniform coating leh bonding strength tha tak a awm theih nan.

Multi-pass coating leh post-treatment : Zawi zawiin a khawlkhawm hmangin target thickness a thleng thei. Hei hi a mamawh thickness thlenna atana core strategy a ni a, a tlangpuiin cycle zawm a ni multiple impregnation — drying — sintering . Single-pass coating thickness rawt chu 0.01mm ~ 0.08mm chhungah control a ni.

·  Drying : 100~150°C ah a lum vek theih nan.

·  Baking : 280~290°C ah a ni a, surfactants a awm loh nan. Dry leh baking inang lo chuan coating-ah crack, bubble emaw pinhole emaw a awm ang.

·  Sintering : 360~390°C, second 30~90 chhung vawn theih a ni. Coating siamna atan chuan sintering hi a pawimawh hle. Temperature hniam lutuk hian coating leh fiber inkara inzawmna tha lo tak a thlen a; temperature sang lutuk hian resin a ti chhe thei.

3. Environmental Factors: Thil pawimawh tak tak, nghawng nei thei thil

Humidity : Ambient humidity chu 40%–60% RH ah khauh taka control tur a ni . Humidity hniam lutuk chuan surface skinning leh internal penetration tling lo a thlen ang; humidity sang lutuk hian sagging, pinholes leh adhesion tihtlem a thlen thei.

Workshop fai : Workshop faina kha khauh taka control la, boruak atanga thil chi hrang hrang impregnation tank chhunga tlak loh nan emaw, undried wet film-ah a innghat lo emaw, chu chuan lei chunglam chhiatna a thlen thei ang.

4. Thurawn tangkai tak tak & Quality Closed-Loop Control

Production guidance : strategy hman a tha . low concentration + multiple impregnation passes  Impregnation times siamrem hmanga total coating thickness dik taka control theih nan Hetihlai hian pre-treatment leh post-treatment procedure te chu standardize la, hei hi high-quality coating dinna bulpui ber a ni.

Troubleshooting : Sintering hnua coating cracking a awm chuan single-pass coating a thick lutuk nge drying speed a rang lutuk tih enfiah thin ang che; coating adhesion a tlem chuan fiber chunglam fai dan bakah sintering temperature leh holding time te enfiah thin ang che.

Quality closed-loop system : Production logic kimchang tak din:  Process parameter control → On-line real-time monitoring → Finished product statistical analysis → Process optimization feedback .
PTFE impregnation hi physicochemical process buaithlak tak a ni a, multi-variable coupling a nei a ni. Stable thickness accuracy chu emulsion formula, process parameter leh environmental condition te huam vek, matched testing methods te huam tel standardized control system siam chauhvin a awm thei a ni.
