Temperature leh Safety Limits – A pawimawh ber
Aokai PTFE chuan PTFE puan him taka hmanna atana thil pawimawh ber pakhat chu temperature control a nih thu a sawi uar hle.
1. Operating temperature sang ber aia tam lo
Standard PTFE fabric hian hun rei tak chhung lumna chhunzawm zel thleng a tuar thei a 260°C , short instantaneous tolerance chu 300°C vel a ni. aia lumna hmunah dah ngai suh 320°C . Khua lum lutuk chuan PTFE coating chu a ti chhe ang a, perfluoroisobutylene ang chi toxic fume a chhuah ang a, hei hian polymer fume fever (flu-like symptoms from inhaling decomposed PTFE) a thlen thei a ni.
Vaukhânna pawimawh tak: 400°C aia sangah chuan PTFE hi a chhe vek a, gas tha lo tak takah a chang a, chung zingah chuan hydrogen fluoride (HF) leh perfluoroisobutylene (PFIB, phosgene aiin ~10x a toxic zawk) te pawh a tel. Puan a dum emaw, rimtui tak a chhuah emaw chuan a hmun chu chhuahsan nghal la, boruak tha tak luh tir rawh.
2. Thli luh theihna tur a awm theih nan hmalak
High-temperature processing pangngaiah pawh hian hnathawhna hmun chu boruak tha taka luh tir la, chu chuan meikhu awm thei zawng zawng hi a luh loh nan. Airflow tha hi hmun inkharkhip emaw, puan chu a temperature sang ber bula hman a nih chuan a pawimawh hle.
3. Meialh zau tak atanga hla takah awm rawh
Flame-retardant ni mahse, fiberglass substrate chu lumna nasa tak hnuaiah a hmin ang a, PTFE coating pawh a chhe vek ang. PTFE puan hi chutiang atana ruahman bik a nih loh chuan direct flame barrier emaw welding blanket emaw atan hmang suh.
PTFE coating hi a te (a tlangpuiin 10-30 μm) a ni a, fiberglass substrate chu a chak a, mahse sharp stress hnuaiah a brittle a ni. Fimkhur takin enkawl rawh.
1. Sharp folding emaw compression rit tak emaw a awm lo
Fabric chu rolled form emaw laid flat emaw-ah dah rawh. Folding hian permanent creases a siam a, chu chuan coating chu a ti crack a, material tensile strength a tichak lo bawk. Vawikhat crease a nih chuan chu line-ah chuan puan chu tension emaw heat emaw hnuaiah a fail ang.
2. Thil hrual atanga scratch awm loh tur
Surface coating-a cut eng pawh hian bare fiberglass a pholang ang a, chu chuan:
awlsam takin moisture a absorb thei
Medium leakage (chemical hmanna atan) a phalsak
Vun ti na thei emaw, vun tichhe thei emaw glass filaments te te a tichhuak thin
Fimkhur takin khawih rawh: PTFE puan bula hnathawh hunah plastic emaw thing hmanrua emaw hmang ang che.
3. A dahna tur hmun dik tak

Thianghlim leh enkawl dan – Gentle Methods chauh
Thianghlim taka tihfai hian puan dam chhung a ti rei thin. Faina dik lo chuan a tichhe vek a ni.
1. Hard abrasive tools hmangin scrub suh
Steel wool leh stiff hard brush hman khap a ni . PTFE coating chu an scratch a, non-stick performance chu a tichhe vek a ni. Residue rilru na tak takte tan chuan:
Tui lum emaw, mild neutral detergent emaw-ah puan chu hnim la, bawlhhlawh a ti nem ang
Tichuan puan nem tak hmangin zawi zawiin phihfai ang che
