PTFE High-Temperature Cloth Sintering laiin Cooling Rate atana thil tul

I. Cooling Rate atana thil tul bulpui

Crystallization-sensitive zone kal tlangin rang takin PTFE melting point chu 327°C a ni a, standard sintering temperature chu 380°C atanga 400°C inkar a ni. Temperature tihhniam lai hian core requirement chu 310~315°C vel temperature zone chu rang taka paltlang a ni a, chutah chuan crystallization rate chu nasa takin a sang ber a ni.

Hman dan tur rawtna Sintering furnace atanga i chhuah hnu lawkah forced air cooling, compressed air blast cooling kalpui la, a nih loh leh cooling rollers / water cooling system hmangin fabric temperature 250°C hnuai lam rang taka tihhniam rawh.

 

Reference cooling rate indicators Product thickness a zirin, general cooling rate chu 30~50°C/min aia tlem lo a ni tur a ni. Thin-gauge high-temperature cloth (0.08mm~0.25mm) tan chuan air cooling hian 100~200°C/min aia cooling rate a nei thei a, critical crystallization zone kaltlangin instantaneous passage a siam thei a ni.

 

II. Process Mechanism: Cooling Rate hian Product Performance a nghawng dan

Crystallinity hian core product property a tichiang Cooling modes hian PTFE crystallinity chu direct-in a thunun a, hei hian key coating characteristics te chu a dictate lehzual a, chung zingah chuan flexibility, adhesion leh non-stick performance te pawh a tel.

 

Fast leh Slow Cooling inkara Performance tehkhin dan

Microstructural Explanation Rapid cooling hian spherulites lian tak tak te chu a tipung thei lo va, microcrystalline structure tha tak a siam bawk. Hei hian PTFE film chu a denser a, a ductile zawk a, chutih rualin coating leh fiberglass substrate inkara residual stress a tihtlem bawk.

Workflow tha zawk chu intensive air cooling down a, 250°C hnuai lam thlenga tihlum belh a ni.

 

Multi-pass sintering atana cooling management Multi-impregnation & multi-sintering process atan chuan intermediate sintering cycle tan chuan moderate fast cooling hi pawm theih a ni. Mahse, surface sintering step hnuhnung ber chuan surface functional performance tha ber neih theih nan rapid cooling a hmang tur a ni.

IV. Core Summary a ni

1. Rapid cooling hi post PTFE cloth sintering tih ngei ngei tur a ni a, hei hian molten PTFE chu high-temperature crystallization zone chu rang taka a skip theih nan a ni.

2. Rapid cooling hian low-crystallinity microcrystalline structure a siam a, hei hi outstanding flexibility, fold resistance leh long-lasting non-stick performance neihna kawngkhar a ni.

3. Cooling uniformity khauh taka regulate, thermal shock ven, leh multi-stage sintering atana cooling schedule standardize, consistent product quality stabilise.
