Engvangin nge Glass Fiber Cloth hi PTFE Emulsion hmanga Impregnation hmain Dewaxing a nih? Principle chu eng nge ni?

PTFE high-temperature fabrics siamtu professional a nih angin Aokai New Materials hian glass fiber puan chungah high-temperature treatment an nei thin a ni. PTFE (Polytetrafluoroethylene) emulsion hmanga impregnation hmain glass fiber puan chu dewaxing leh degumming hmangin fiber chunglama sizing agents (textile auxiliaries) te chu paih chhuah a ni. Heng auxiliary te hian fiber drawing leh weaving neih laiin bundling, lubrication leh protection atan an thawk a ni. Mahse, an paih loh chuan PTFE leh glass fiber composite quality nasa takin an tichhe dawn a ni. Thu bulte chu a bul berah chuan hetiang hi a ni:

1. Low Surface Energy Substances te paih chhuakin Wettability tihchangtlun

Sizing agents-a paraffin, lubricating oil leh component dangte hi surface energy hniam tak tak an ni. Retain a nih chuan PTFE emulsion (surface tension hniam tak nei mahse requirement khauh tak nei) chu glass fiber surface-ah a darh zau thei lo va, chu chuan crater leh fish eyes ang chi chhiatna a thlen thei a ni. High-temperature thermal cleaning emaw solvent cleaning hmangin bawlhhlawh paih chhuah a ni a, glass fiber chunglam energy a tipung a, hei hian PTFE hmangin full wetting a siam thei a ni.

2. High-Temperature Sintering laiin Carbonization leh Delamination ven

PTFE sintering temperature hi 360–380°C vel a ni. Glass fiber chunglama paraffin emaw epoxy adhesives awmsa te chu chutiang temperature sang takah chuan carbonize ang a, black particle emaw gas emaw a siam chhuak ang. Hei hian medium a ti bawlhhlawh mai bakah (high-frequency copper-clad laminates-a dielectric property a nghawng) a, a pawimawh zawk chu carbonized layer hian interface chak lo tak a siam a, PTFE leh glass fiber inkara bonding strength nasa takin a tihtlem a, composite material chu delamination a thlen a ni.

3. 'Mechanical Anchoring' Effect chak tak din rawh

Dewaxing leh degumming quality sang tak (a bik takin high-temperature heat treatment) hi 'cleaning' mai ni lovin a tam zawk. Organic matter lakchhuah a nih chuan glass fiber chunglam chu tlem etched a ni a, micropores siam emaw silanol group (-OH) tam zawk a pholang emaw a ni. Hei hian a hnu lama coupling agent coating (eg, phenyl silane) neih theihna tur dinhmun a siam a, PTFE chu coupling agents hmangin glass fiber nen chemical bonds emaw physical anchoring point emaw siam turin a phalsak a — simple 'coating' chu firm 'bonding'-ah a chantir thei a ni.

4. Interfacial Dielectric Properties tihchhiat loh tur

High-end application, high-frequency leh high-speed copper-clad laminates-ah chuan residual polar organic substance (wax, gum) te hian temperature sang leh frequency sang hnuaiah dielectric loss nasa takin a tipung a ni. Dewaxing leh degumming hian glass fiber-PTFE composite hian dielectric constant leh dielectric loss hniam tak tak a vawng reng thei a ni.

A tawi zawngin, he enkawlna hian a tum ber chu interface layer chak lo tak takte tihbo a, PTFE, surface energy hniam tak material chuan thianghlim, high-surface-energy glass fiber-a wetting ṭha famkim leh high-strength bonding a neih theih nan a ni.
