Izicelo ze-PTFE Rod

I-PTFE RodIzici:Ibanga lokushisa lokusetshenziswa libanzi kakhulu (Celsius kusuka -200 degrees kuya +260 degrees);Ukugqwala kwento yamakhemikhali e-anti-majority, ngaphandle kwama-fluoride athile kanye ne-alkalinity moltenmetal;Izici zemishini ezinhle kakhulu, ukumelana nokuguga;Ukumelana nelangabi okuhle kakhulu (Kuvumelana nesinyathelo sokuhlola se-ASTM-D635 ne-D470), emoyeni ukuze ilawulwe njengento ebambezela ilangabi;Iphansi kakhulu ukumuncwa kwamanzi……

I-PTFE-polytetrafluoroethylene yatholwa nguDkt. Roy Plunkett we-DuPont Research Laboratory ngo-April 6, 1938. I-PTFE yoqobo yathuthukiswa ngokuqhubekayo yi-Dupont futhi yakhululwa njengomkhiqizo ngo-1945.

Umkhiqizo umelana kakhulu nokugqwala kwamakhemikhali futhi ukwazi ukuphatha amazinga okushisa angaphezu kuka-500 ° C. Enye yezinto zasendlini zokuqala ze-PTFE “i-PTFE camera frying pan”.Nakuba ibhodwe lisebenza kahle kakhulu, lihlukile ezindongeni ze-PTFE namapuleti esiwahlinzekayo.Ifuthwa cishe ku-coat emnyama, izinti ezihlanzekile ze-PTFE namashidi kuphakheji ye-PTFE yebha eyindilinga yevalve yesitimu imhlophe ngokugqamile ukuthi zisetshenziswa kanjani izinti zepulasitiki ze-PTFE zemboni ukuthi zisetshenziswa kanjani izinti zepulasitiki ze-PTFE ze-PTFE gaskets kanye nokupakishwa kwesitimu.

Ngenxa yokuthi i-PTFE inokushisa okuphezulu nokumelana namakhemikhali, ivamise ukusetshenziselwa izicelo zamavalvu.Ukusuka kumavalvu alula wesitimu/amanzi ashisayo kuya kumazinga okushisa aphezulu, izimboni ezibamba uketshezi ezisebenza ngamavalvu amakhemikhali e-caustic.Le nto iqinile kuya kupulasitiki oqinile futhi ingenziwa ngomshini kalula - enye yepulasitiki elula ukuyisebenzisa.Induku ye-PTFE ingenziwa ngomshini ibe ukubekezelelana okusondele kakhulu kuma-rod amaningi amancane anobubanzi obungu-+.002 “/ — .00”.Ukumelana namakhemikhali kungenye yezinto ezibalulekile ezihlobene nezinto zokwakha.Kuma-flakes noma ama-flakes, i-PTFE isetshenziswa njengempahla ye-gasket ekushiseni okuphezulu nama-flange amelana namakhemikhali nama-seal.
