Ndi zinthu ziti zomwe zimakhudza nthawi yogwiritsira ntchito PTFE chubu chitoliro

Mkuwa wodzaza ptfe chubu, yomwe imadziwika kuti polytetrafluoroethylene chubu (F4 chubu, tetrafluoroethylene chubu), ndi chubu chapamwamba cha plunger extruded chubu ndipo chimagwiritsa ntchito luso lapadera lokonzekera kuti liphatikize zitsulo ndi machubu apulasitiki.Teflon chubu akhoza kupirira zoipa kuthamanga 77 kpa1.6 Mpa, komanso angagwiritsidwe ntchito kawirikawiri mu kutentha osiyanasiyana 60 ℃260 ℃, ali ndi odalirika komanso kukana dzimbiri.Choncho, amagwiritsidwa ntchito kwambiri mu makina, makampani mankhwala, magetsi, zamagetsi, chitetezo makampani, luso kutsogolo, ukhondo, kutchinjiriza magetsi ndi zina.Poyerekeza ndi mapaipi ena,mkuwa wodzaza ptfe chubuakhoza kunyamula mpweya zikuwononga ndi zamadzimadzi pa kutentha, amene ndi wapadera kwa PTFE chitoliro.
Popeza chitoliro cha PTFE ndi champhamvu kwambiri, kodi chingawonongekebe?Yankho ndiloti inde, pambuyo pa zonse, pogwiritsa ntchito chubu la tetrafluoro, chifukwa cha zinthu zosiyanasiyana, chubu la tetrafluoro likhoza kuwonongeka ndikusweka.Ndiye, ndi zinthu ziti zomwe zingakhudze nthawi yogwiritsira ntchito teflon chubu pogwiritsira ntchito chubu la teflon?Kenako, chonde nditsatireni kuti mumvetse.
Zikafika pazifukwa zomwe zimakhudza nthawi yogwiritsira ntchito tetrafluoro chubu, pali mitundu yambiri ya zinthu, zomwe zingakhale zochokera kuzinthu zake, kapena mwina chifukwa cha mayendedwe ake, kapena chifukwa cha chilengedwe.Mafotokozedwe achindunji ali motere.
1. Zinthu za PTFE chubu palokha
Makamaka amatanthauza chubu chotsika cha teflon, ndiko kuti, njira yolakwika ndi njira ya wopanga machubu a teflon, kapena kusowa kwa kukhudzana popanga chubu cha teflon.Mwanjira imeneyi, machubu a teflon omwe amapangidwa amakhala ovuta kwambiri pankhani yaubwino ndipo amakhala osalimba.Kamodzi kukhudzidwa ndi munthu, kuwonongeka ndi fractures zikhoza kuchitika mosavuta.Kumene, izi ndi osowa, pambuyo pa zonse, zidzakhudza njira yonse yogwiritsira ntchito tetrafluoro chubu, ndipo ngakhale kuika miyoyo ya antchito pangozi.
2.Teflon chubu kutengera sing'anga
Ngati sing'anga imatengedwa ndiPTFE chubu chitolirondi kutentha kwambiri, kuwononga kwambiri komanso madzi olemera kwambiri, kuphatikizapo ali ndi vuto pang'ono lokha, chubu cha PTFE chikhoza kulephera kupirira panthawi yogwiritsira ntchito.Chifukwa cha kutentha kwambiri, kupanikizika ndi kwakukulu kwambiri komanso kuphulika.
3. Malo ogwirira ntchito chubu la Teflon
Monga ife tonse tikudziwa, PTFE chitoliro angagwiritsidwe ntchito bwinobwino mu kutentha osiyanasiyana -60 ℃260 ℃, koma ngati kutentha ntchito PTFE chitoliro ndi yachibadwa poyamba, ndiye mwangozi upambana osiyanasiyana, ndiye zingachititse chitoliro kuti. kuphulika chifukwa cha kutentha mkati mwa chitoliro ndi kutentha kunja kwa chitoliro.
Zitha kuwoneka kuti mukamagwiritsa ntchito chitoliro cha teflon, chimayenera kugwiritsidwa ntchito mosamalitsa molingana ndi muyezo osati kuti chikhale chotentha kwambiri, kuthamanga kwambiri komanso dzimbiri.Ndi njira iyi yokha yomwe tingagwiritsire ntchito kwa nthawi yayitali.
