Service Life Tichhe thei General Factors – Scenario zawng zawngah hman theih a ni
Application bik i en hmain PTFE fabric dam chhung ti tawi emaw, ti sei emaw tu universal factors te hi hrethiam hmasa phawt ang che.
1. Temperature control hi a pawimawh hle
Hun rei tak chhunga hnathawhna temperature range chu -70°C atanga 260°C thleng a ni . 350°C thlenga zin rei vak lo chu a awm thei a, mahse hun rei tak a lum lutuk chuan material structure a tichhia a, a dam chhung pawh nasa takin a ti tawi bawk.
Test data: Material hian ni 200 chhung 250°C-a a awm chhunzawm zel hnuah a performance a vawng reng a ni.
Rule of thumb: 260°C aia sang 10°C apiangin degradation rate chu a let hnih velin a pung thin. A huam chin chhungah dah rawh.
2. Taksa chhiatna pumpelh rawh – sharp creases hi hmelma a ni
Installation leh operation laiin sharp creases awm lo turin venhim. Creases hian stress concentration point a siam a, awlsam takin tearing a thlen thei – a bik takin conveyor belt atana hman a nih chuan. Vawikhat crease line a lo awm chuan a hnuaiah fiberglass substrate chu a chhe a, coating chu a chhe ta a ni.
3. Chemical exposure leh contamination
PTFE hian acid chak tak tak leh alkali te chu a do tha hle. Mahse, hun rei tak chhunga oil stain, hot melt adhesives, emaw pigment emaw temperature sang taka inhnaih chuan coating aging a ti chak thei a ni. PTFE hi inert ni mahse, residual substance te hian a chung lamah carbonize in release property a tichhe thei a ni.
4. Mechanical hmanga a chhe thei lo
Friction leh tension chhunzawm zel chuan surface coating chu a ti chhe vek. Puan chu thil hrual atanga hla takah dah tur a ni. Sliding application atan chuan filled PTFE grades emaw regular lubrication emaw ngaihtuah tur a ni.
5. Enfiah leh thlak ngai reng reng
Thla thum danah routine maintenance leh inspection neih thin a, a thawh that theih nan. Key production line tan chuan a inthlak danglam theih nan spare set buatsaih rawh. Wear hriat hmasak hian catastrophic failure a veng thei.
