Simbi dzakaiswa PTFE mapaipi uye mafittings anonakidzwa nemukurumbira we "King of Plastics", ine tembiricha yakanakisa uye inodzivirira ngura, uye yakanakira kufambisa yakasimba corrosive media senge nitric acid, sulfuric acid, hydrofluoric acid, phosgene, chlorine, aqua regia, musanganiswa acids, bromides nezvimwe zvinonyungudutsa organic. Steel lined PTFE piping uye fittings zvinogona kushanda zvakadzikama pakupisa kwepamusoro (mukati me150 ° C) pasi pemamiriro ezvinhu asina kunaka asina kunaka kwenguva yakareba yakagadzirisa kukanganisa kwesimbi yapfuura yakavharidzirwa PTFE pombi uye zvigadziro zvisingagoni kurwisa kudzvinyirira kwakashata uye zvinoshandiswa zvakanyanya mune dzakawanda distillation uye mamwe kupisa kwepamusoro uye high negative pressure systems.
Simbi yakamisikidzwa teflon push-pressure pombi inongori mashandiro emuchina, kana ichienzaniswa nedzimwe simbi yakamisikidzwa teflon pombi yekugadzirisa tekinoroji, iyo simbi yakamisikidzwa teflon pombi inogadzirwa ine: yakakwirira density, yakatsetseka pamusoro, yunifomu ukobvu uye humwe hunhu. Iyo "high density" inodzivirira iyo yepakati kubva mukati uye haisi nyore kuremara mukushandiswa; iyo "smooth surface" inoita kuti kumira kwepakati kuyerera kudiki uye kunodzivirira kudzivirira kunamatira; iyo "yunifomu ukobvu" inoita kuti Simbi yakarongedzerwa PTFE pombi ine simba rakawanda uye yakanaka yekuisa chisimbiso kuita paflange. Inokodzera kwakasiyana siyana acids, alkalis, yakasimba oxidants, aqua regia uye imwe yakasimba corrosive media.
Kuenzaniswa nedzimwe simbi dzakagadzirwa neTeflon mapaipi, simbi yakasungirirwa Teflon mapaipi ane maitiro anotevera: high density, smooth surface, uniform thickness, etc. Iyo "high density" inodzivirira svikiro kupinda mukati uye haisi nyore kuremara mukushandiswa; iyo "smooth surface" inoita kuti kumira kwepakati kuyerera kudiki uye kunodzivirira kudzivirira kunamatira; iyo "yunifomu ukobvu" inoita kuti Simbi yakarongedzerwa PTFE pombi ine simba rakawanda uye yakanaka yekuisa chisimbiso kuita paflange. Inokodzera kwakasiyana siyana acids, alkalis, yakasimba oxidants, aqua regia uye imwe yakasimba corrosive media.
Fluorine yakavharwa pombi lining ukobvu
