Inqubo yokukhiqizaIshubhu le-PTFEyi: PTFE, usizo lokukhipha → ukuxuba → ukucindezela → ukomisa → ukuthulula → ukupholisa → umkhiqizo
Inqubo yokubumba yamashubhu e-PTFE ifaka phakathi indlela yokusunduza, indlela yokukhipha, indlela ye-hydraulic, indlela yokushisela, indlela yokugoqa, njll., phakathi kwazo indlela yokusunduza iyindlela eyinhloko. Ngokuvamile, kusetshenziswa i-resin ye-PTFE ehlakazekile enosayizi wezinhlayiya ezingu-500μm kanye nobuningi obubonakalayo obungu-0.45gml ~ 0.55gml. Kumashubhu amancane obubanzi, sebenzisa i-resin enokucindezela okukhulu, kanti kumashubhu amakhulu obubanzi, sebenzisa i-resin enokucindezela okuncane. I-pressure aid ivame ukukhetha imimoya yamaminerali engu-200 no-260. Ukucubungula kwesibili kwamashubhu e-PTFE kungakhiqiza amashubhu anciphayo e-PTFE, amashubhu ajikelezayo e-PTFE, amashubhu e-hydraulic e-PTFE, njll.
Ishubhu le-polytetrafluoroethylene lenziwe nge-resin ehlakazekile ye-polytetrafluoroethylene ekushiseni kwegumbi kusetshenziswa i-solvent ephilayo njengosizo lokukhipha, bese yomiswa bese ishiswa. Ngokusho kobubanzi beshubhu, ingahlukaniswa ngezinhlobo ezimbili: ishubhu evamile kanye neshubhu elincane. Ububanzi bangaphakathi beshubhu elijwayelekile bungu-4mm, kanti ububanzi bangaphakathi beshubhu elincane bungaphansi noma bulingana no-4mm.
Inqubo yokukhiqiza ithubhu le-PTFE yile: i-PTFE, usizo lokukhipha → ukuxuba → ukucindezela → ukomisa → ukuthulula → ukupholisa → umkhiqizo.
Amashubhu e-polytetrafluoroethylene anamandla amahle okusebenza. Ama-gasket angama-gasket asicaba, ama-gasket anomumo ongu-V, amasongo e-piston, ama-gasket e-ball valve, njll., enziwe ngezinduku ze-PTFE, amashubhu, namapuleti ngokujika noma ukusika ngomshini, amelana nokugqwala, ukumelana nokumelana nokushisa kanye nokungaqhubi kahle.
1. Amashubhu e-Teflon ngokuvamile asebenzisa indlela yokubumba yokucindezela, futhi ukubumba kwe-plunger extrusion nakho kungasetshenziswa. I-resin etholakala ngendlela ye-dispersion polymerization ingakhiwa ngokunamathisela i-extrusion kanye ne-calendering.
2. I-PTFE inenani le-pH elingu-0-14 (ngaphandle kwezinsimbi ze-alkali ezincibilikisiwe kanye ne-fluorine ngaphansi kokushisa okuphezulu kanye nomfutho ophezulu), okungaba namandla amahle okusebenza phakathi kuka-100°C no-100°C.
3. Izimo zenqubo ethile ziwukuthi ingcindezi yokulungiselela iyahlukahluka ngokuma nosayizi womkhiqizo. Kodwa ivame ukusetshenziswa. Ukupakisha okulukiwe nge-Teflon kungu-8-34.3MPa, kanti i-resin ene-filler ingu-29.4-93MPa. Kuboya obukhulu obunobukhulu obungu-600mm ohlangothini lokucindezela, kusenesikhathi sokubamba ingcindezi semizuzu engu-20-30. Qaphela ukuthi uma izinga lokushisa liphansi kuka-185°C. Amapayipi e-Teflon azophuka. I-PTFE gasket emsulwa iwumkhiqizo wokuvala ohlanzekile ongeke ungcolise noma iyiphi into ehlangana nayo futhi ingasetshenziswa kabanzi ekudleni, emithini nakwezinye izimboni.
