Awọn ohun elo Laini: PTFE (Polytetrafluoroethylene), PFA (Perfluoroalkoxy), ETFE (Tefzel®, ethylene tetrafluoroethylene), PVDF (Polyvinylidene Fluoride), PP (Polypropylene)…

PTFE (Polytetrafluoroethylene)

PTFE, Fluoropolymer ti o wọpọ julọ ti a lo, ni aabo ipata otutu giga ti o dara julọ si gbogbo awọn kemikali ti o fẹrẹẹ jẹ ayafi fluorine ipilẹ ati awọn irin alkali didà.Ni afikun, PTFE ni awọn ohun-ini alailẹgbẹ ti kii ṣe ọpá eyiti o le dinku tabi imukuro ikojọpọ awọn ohun idogo lori awọn odi paipu.Awọn iwọn otutu iṣẹ ni awọn ọna fifin titẹ wa lati -20°F (-29°C) si 450°F (230°C).

PFA (Perfluoroalkoxy)

PFA ṣe afihan resistance kemikali ti o jọra si PTFE.Dara fun iṣẹ lati 0°F si 450°F, PFA jẹ thermoplastic fluorinated ti a mọ fun awọn agbara-pure-pure rẹ.PFA pese resistance ti nrakò ti o ga julọ ni iwọn otutu giga, lile iwọn otutu kekere ti o dara julọ ati resistance ina alailẹgbẹ.

ETFE (Tefzel®, ethylene tetrafluoroethylene)

Tefzel® daapọ lile darí pẹlu atako kẹmika ti o tayọ ti o sunmọ polymer®.Ti o munadoko lati -20°F si 300°F, Tefzel ni irọrun ni ilọsiwaju ati pe a mọ fun agbara itọsi itankalẹ agbara giga rẹ.

PVDF (Polyvinylidene fluoride)

PVDF ni o ni o tayọ resistance si ọpọlọpọ awọn kemikali, pẹlu halogens ati ki o lagbara oxidants.PVDF ṣe afihan abrasion ti o dara julọ ati resistance permeation.Bi PSI ṣe nlo mejeeji homopolymer (6 ″ – 8 ″ awọn ibamu) ati awọn resini copolymer (1 ″ – 8″ paipu, 1″ – 4″ paipu), eto laini PVDF jẹ iwọn lati 0°F (-29°C) si 275°F (135°C).Nitoripe PVDF jẹ fluorinated kan ni apakan, resistance kemikali rẹ ni ipa nipasẹ iwọn otutu ati ifọkansi ti awọn olomi ati awọn gaasi.

PP (Polypropylene)

Awọn lilo PP homopolymer PSI ni resistance ipata to dara, gbigba ọrinrin kekere, ati awọn ohun-ini ẹrọ ti o dara.Niwọn igba ti resistance kemikali rẹ ni ipa pupọ nipasẹ ifọkansi ati iwọn otutu ti omi ti a gbejade, lilo rẹ ni awọn eto fifin titẹ jẹ opin ni gbogbogbo lati 0°F (-16°C) si 225°F (107°C).
