Engvangin Nge PTFE High-Temperature Cloth hi Temperature sang takah Hun rei tak hman a nih hnuah a khauh leh a chhe thei lo?

PTFE high-temperature cloth source siamtu Jiangsu Aokai New Materials chuan PTFE high-temperature cloth hi hun rei tak high-temperature service hnua a hardening leh embrittlement chungchang hi kawng pathum atangin a sawifiah a: polymer chain relaxation, cross-linking, leh degradation Hriat tur chu PTFE high-temperature cloth-a core material chu polytetrafluoroethylene (PTFE) a ni a, a hnuaia analysis hian PTFE high-temperature cloth-a microstructural changes a ngaihtuah ber a ni.

I. Molecular Chain Relaxation (Taksa tar chakna) .

Temperature sang takah chuan PTFE high-temperature cloth-a amorphous region-a molecular chain-te mobility a sang a, zawi zawiin ordered zawk crystalline state-ah an inthlak a, chu chuan crystallinity sang zawk a siam a ni. He chain relaxation process hian PTFE high-temperature cloth-a molecular segment-te mobility a ti tlem a, hei hi macroscopically-in material chu flexible atanga hard leh brittle-a a inthlak angin a lang chhuak a ni.

II. Cross-Linking Reaction hmanga thil tih dan

PTFE high-temperature cloth chu temperature sang takah rei tak (a bik takin a upper service limit hnaih emaw, a aia sang emaw) a awm chuan, trace oxygen emaw radiation emaw awmnaah chuan PTFE molecule te hian fluorine atom an hloh a, free radicals an siam a, chu chuan intermolecular cross-linking a tichhuak a ni. Cross-linked network hian PTFE high-temperature cloth-a molecular chain-te relative sliding chu direct-in a khap a, chu chuan a flexibility a hloh phah a ni. Hei hi PTFE high-temperature cloth hardening leh embrittlement atana chemical chhan pawimawh tak pakhat a ni.

III. Degradation Reaction tih hi a ni

Temperature sang zawkah emaw, oxygen awmnaah emaw chuan PTFE high-temperature cloth chain lian ber berte chu a chhe a, a chhe a, molecular-weight hniam fragment a siam a, fluoride gas a chhuak bawk. A tir lamah chuan material chu a nem thei a, mahse a chhe zel chuan molecular weight nasa takin a tlahniam a, original crystalline structure a tichhia bawk. A tawpah chuan PTFE high-temperature cloth powders chunglam chu a crack a, irreversible embrittlement a lantir bawk.

Summary : PTFE high-temperature cloth chu rei tak a lum chuan chain relaxation (crystallization) leh cross-linking inzawmkhawm hian hardening leh toughness hloh a thlen a dinhmun khirh takah chuan degradation hian structural integrity a tichhe zual sauh a ni. Heng thil pathumte inzawmkhawm hian a tawpah chuan PTFE high-temperature cloth chu a khauh a, a ti chhe thei bawk.
