Polytetrafluoroethylene (PTFE) yog ib qho hluavtaws fluoropolymer ntawm tetrafluoroethylene uas muaj ntau daim ntawv thov.Lub npe nrov tshaj plaws ntawm PTFE-based…
PTFE yog polymer uas tau siv dav hauv tshuaj lom neeg, tshuab, hluav taws xob & hluav taws xob kev lag luam vim nws cov yam ntxwv tshwj xeeb.
- Kev siv tshuaj lom neeg rau txhua yam tshuaj uas paub tab sis raug tawm tsam los ntawm cov hlau alkali, chlorine, trifluorides, fluorine & lwm yam fluorine complexes ntawm qhov kub thiab txias.
- Ua hauj lwm rau cov kuab tshuaj, insoluble nyob rau hauv tag nrho cov kuab tshuaj mus txog 260 ° C tej cov roj fluorinated siab swell & yaj PTFE ntawm qhov kub thiab txias ze rau crystalline melting point.
- Kev khiav hauj lwm dav kub ntau -250 ° C txog + 260 ° C, ntawm atmospheric siab.
- Tsawg coefficient ntawm kev sib txhuam ntawm tag nrho cov paub hlau & nonmetals.
- Nontoxic & anti-stick zog.
- Kev nqus dej tsis txaus.
- Nonflammable.
- Kev tiv thaiv hluav taws xob, cov khoom hluav taws xob nyob twj ywm tsis hloov pauv thaum lub sijhawm & tom qab irradiation, ob qho tib si hauv huab cua & lub tshuab nqus tsev.
- Zoo heev huab cua tsis kam.
