PTFE High-Temperature Cloth hian Ozone Aging a do thei

PTFE high-temperature cloth siamtu professional leh source factory Jiangsu Aokai New Materials chuan chipchiar takin a rawn tarlang a. Polytetrafluoroethylene (PTFE) coated fiberglass puan hian chemical inertness tha tak a nei a, a tlangpuiin ozone aging resistance ropui tak a pe chhuak thin. Mahse, ozone erosion lakah a him tawk lo va, a performance pum pui hi ozone concentration, ambient temperature, continuous exposure time leh pawn lam thil dangte hian nasa takin a nghawng a ni.

A molecular structure danglam tak avang hian PTFE hian standard condition hnuaiah ozone resistance chak tak a lantir a ni. Fully fluorinated carbon-fluorine (CF) bond hian bond energy sang tak tak 485 kJ/mol vel a nei a ni. Hetihlai hian a spiral molecular structure chuan fluorine atom dense protective shield a siam a, chu chuan ozone ang chi oxidant chak tak takte chuan internal carbon-carbon (CC) main molecular chain a beih loh nan a veng a ni.

Chuti chung pawh chuan ozone hian PTFE chunglam ziarang nasa takin a tidanglam thei a, chemical leh physical change hrang hrang a thlen thei bawk. Zirna hrang hrangah chuan ozone-a PTFE awm hian boruak pangngai aiin friction coefficient a let thum velin a sang zawk tih hmuhchhuah a ni a, chu chu wear mark langsar tak tak nen a inzawm a ni. Hei hi ozone avanga surface oxidation, molecular bond breakage leh material softening vang a ni ber.

Hun rei tak chhung ozone-a inhriat a nih chuan, a bik takin hnathawhna hmun khirh tak tak, temperature sang leh ozone concentration sang tak hnuaiah chuan PTFE high-temperature cloth chu microscopic damage atanga macroscopic functional failure thlengin a lo thang zauh zauh ang a, failure manifestations bik chu a hnuaia mi ang hian a awm ang:

Molecular chain chhe leh chhe Ozone hian PTFE CC molecular chain te chu a tichhia a, molecular fragment te te, carbon tetrafluoride (CF4) leh carbonyl fluoride (COF2) te a siam chhuak thin. Hei hian molecular weight a tihhniam bakah material chu a fundamental performance degradation a thlen thin.

Surface cracking leh embrittlement Kum upa lam thil hriat theih ber a ni. Material hian surface flexibility a hloh a, stress hnuaiah network ang chi bright crack a siam a, chu chu ozone cracking a ni. Puan chu a nghet a, a chhe thei bawk a, upa lutuk chuan pulverization leh structural damage a thlen belh zel ang.

Mechanical property tlahniam Material degradation hian tensile strength, elongation at break, elasticity leh core mechanical indicator dangte a tihhniam chhunzawm zel a ni. A hnu lama surface pulverization, peeling leh thickness tihtlem te hian wear resistance leh structural stability a tichak lo zual ang.

Surface structural property chhiatna Chemical structural damage hian key parameters, surface energy leh wetting angle te a tidanglam thin. Ozone erosion avanga microscopic crack leh pores lo awmte chu a lianin a zau ang a, original sealing leh isolation performance nasa takin a tichak lo ang.

PTFE high-temperature cloth-a ozone resistance hi base material ngei hian a hril lo. Ambient temperature, combined aging effects leh pawn lam thil dangte pawhin a service life-ah thutlukna pawimawh tak a chang bawk.
