Plastic Liner Materials

Liner Zvishandiso: PTFE (Polytetrafluoroethylene), PFA (Perfluoroalkoxy), ETFE (Tefzel®, ethylene tetrafluoroethylene), PVDF (Polyvinylidene Fluoride), PP (Polypropylene)…

PTFE (Polytetrafluoroethylene)

PTFE, iyo inonyanya kushandiswa fluoropolymer, ine yakanakisa kutonhora kwekushisa kwekudzivirira kune angangoita ese makemikari kunze kwe elemental fluorine uye yakanyungudutswa alkali simbi.Pamusoro pezvo, PTFE ine zvimiro zvisina kujairika zvisiri zvetsvimbo izvo zvinogona kuderedza kana kubvisa kuunganidzwa kwemadhipoziti pamadziro epombi.Masevhisi tembiricha mukumanikidza pombi masisitimu anotangira -20°F (-29°C) kusvika 450°F (230°C).

PFA (Perfluoroalkoxy)

PFA inoratidza kuramba kwemakemikari kwakangofanana nePTFE.Inokodzera sevhisi kubva pa0 ° F kusvika 450 ° F, PFA ndeye fluorinated thermoplastic inozivikanwa nekugona kwayo kwekupedzisira-kuchena.PFA inopa yakakwira kukwira kupikisa pakupisa kwepamusoro, yakanyanya kuderera tembiricha kusimba uye yakasarudzika murazvo kuramba.

ETFE (Tefzel®, ethylene tetrafluoroethylene)

Tefzel® inosanganisa kusimba kwemechini uye yakasarudzika makemikari kuramba inoswedera ku polymer®.Inoshanda kubva -20 ° F kusvika 300 ° F, Tefzel inogadziriswa zviri nyore uye inozivikanwa nekukwira kwayo kwemwaranzi yemagetsi kuramba.

PVDF (Polyvinylidene Fluoride)

PVDF inopikisa zvakanyanya kumakemikari akawanda, anosanganisira halogens uye akasimba oxidants.PVDF inoratidza yakanakisa abrasion uye permeation kuramba.Sezvo PSI inoshandisa zvese homopolymer (6 ″ - 8 ″ fittings) uye copolymer resin (1 ″ - 8 ″ pombi, 1 ″ - 4 ″ fittings), iyo PVDF lined system yakarongwa kubva pa0 ° F (-29 ° C) kusvika 275°F (135°C).Nekuti PVDF inongorimwa zvishoma, kupikisa kwemakemikari kunokanganisa tembiricha uye kusangana kwezvinwiwa nemagasi.

PP (Polypropylene)

Iyo PP homopolymer PSI inoshandisa ine yakanaka corrosion kuramba, yakaderera mwando kunyudza, uye yakanaka mechanic zvivakwa.Sezvo kupikisa kwayo kemikari kuchikanganiswa zvakanyanya nekudzika uye tembiricha yemvura inofambiswa, kushandiswa kwayo mukumanikidza pombi masisitimu kunowanzo kuganhurwa kubva pa0 ° F (-16 ° C) kusvika 225 ° F (107 ° C).
