I-PTFE PFA enomugqa Amapayipi ensimbi amaningi afanele amagesi agqwalayo aqinile noketshezi emazingeni okushisa aphezulu.Ezinye izinhlobo zamapayipi ahlanganisiwe ensimbi-eplastiki namapayipi ensimbi awafanele ukudlulisa imidiya.Amapayipi ayinhlanganisela yensimbi ye-PTFE afanelekile.Ngaphezu kwalokho, ipayipi eliyinhlanganisela ye-polyvinylidene fluoride yensimbi ilungele ukuthutha imidiya egqwalayo enezinga lokushisa elisebenzayo elingu -40℃~+150℃.

Isingeniso Esifushane Sokucubungula Ubuchwepheshe Bepayipi Lensimbi Le-PTFE Elilayiniwe

Indlela ye-steel-lined tetrafluorotube sodium naphthalene solution bonding

I-Polytetrafluoroethylene (PTFE) -isixazululo se-sodium naphthalene yokwelapha indlela yokuhlanganisa: ukwelashwa kwesisombululo se-sodium naphthalene sezinto eziqukethe i-fluorine, ikakhulukazi ngokusabela kwamakhemikhali oketshezi olubolayo ngepulasitiki ye-PTFE, kudabula ingxenye yama-athomu e-fluorine ebusweni bento, ukuze ingaphezulu Isendlalelo se-carbonized futhi amanye amaqembu e-polar asele kuso.

Ukwelashwa kwesisombululo se-sodium naphthalene yezinto eziqukethe i-fluorine ikakhulukazi ngokusabela kwamakhemikhali phakathi koketshezi olubolayo kanye nepulasitiki ye-PTFE ukudabula ingxenye yama-athomu e-fluorine ebusweni bento, ngaleyo ndlela kushiye ungqimba olune-carbonized kanye namaqembu athile amhlophe phezulu.I-spectrum ye-infrared ibonisa ukuthi amaqembu e-polar afana ne-hydroxyl, i-carbonyl ne-unsaturated bond yethulwa phezulu.Lawa maqembu angakhuphula amandla angaphezulu, anciphise i-engeli yokuthintana, athuthukise ukumanzisa, futhi ashintshe asuke kunzima ukuya kokunamathelayo kuye kokunamathelayo.Lena indlela ephumelela kakhulu futhi evame ukusetshenziswa phakathi kwazo zonke izindlela ezifundwayo njengamanje.Ngokuvamile, i-sodium naphthalene tetrahydrofuran isetshenziswa njengekhambi lokunamathisela.
