Izinto zePlastiki zeLiner

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

I-PTFE (iPolytetrafluoroethylene)

PTFE, eyona fluoropolymer esetyenziswa ngokuqhelekileyo, inokumelana nobushushu obuphezulu be-corrosion phantse kuzo zonke iikhemikhali ngaphandle kwe-elemental fluorine kunye neentsimbi zealkali ezityhidiweyo.Ukongeza, i-PTFE ineempawu ezingaqhelekanga ezingabambekiyo ezinokunciphisa okanye ziphelise ukwakhiwa kweedipozithi kwiindonga zemibhobho.Amaqondo obushushu benkonzo kwiinkqubo zemibhobho yoxinzelelo ukusuka ku-20°F (-29°C) ukuya kuma-450°F (230°C).

PFA (Perfluoroalkoxy)

I-PFA ibonisa ukuxhathisa kweekhemikhali ngokuphantse kufane ne-PTFE.Ifanele inkonzo ukusuka kwi-0 ° F ukuya kwi-450 ° F, i-PFA yi-thermoplastic ene-fluorinated eyaziwa ngokuba ne-ultra-pure.I-PFA ibonelela ngokuxhathisa okuphezulu kwiqondo lobushushu eliphezulu, ukuqina kobushushu obuphantsi kunye nokuxhathisa okukhethekileyo kwedangatye.

I-ETFE (Tefzel®, ethylene tetrafluoroethylene)

I-Tefzel® idibanisa ukuqina komatshini kunye nokumelana neekhemikhali ezibalaseleyo ezisondela kwi-polymer®.Isebenza ukusuka ku -20 ° F ukuya kwi-300 ° F, iTefzel icutshungulwa ngokulula kwaye yaziwa ngokuxhathisa kwayo kwimitha yamandla aphezulu.

I-PVDF (iPolyvinylidine Fluoride)

I-PVDF inokumelana okugqwesileyo kwiikhemikhali ezininzi, kuquka ii-halogens kunye nee-oxidants ezinamandla.I-PVDF ibonisa i-abrasion egqwesileyo kunye nokumelana nokungena.Njengoko i-PSI isebenzisa zombini i-homopolymer (6″ – 8″ fittings) kunye ne-copolymer resins (1″ – 8″ pipe, 1″ – 4″ fittings), inkqubo ye-PVDF enemigca ilinganiswe ukusuka ku-0°F (-29°C) ukuya 275°F (135°C).Ngenxa yokuba i-PVDF ihlulwe ngokuyinxenye, ukuxhathisa kwayo kweekhemikhali kuchatshazelwa bubushushu kunye nokuxinana kolwelo kunye neegesi.

I-PP (iPolypropylene)

I-PPI ye-homopolymer ye-PSI esetyenziswayo inokumelana nokugqwala okulungileyo, ukufunxa ukufuma okuphantsi, kunye neempawu ezilungileyo zoomatshini.Ekubeni ukuxhathisa kwayo kweekhemikhali kuchaphazeleka kakhulu kugxininiso kunye nobushushu bolwelo olugqithisiweyo, ukusetyenziswa kwayo kwiinkqubo zemibhobho yoxinzelelo ngokuqhelekileyo kukhawulelwe ukusuka kwi-0 ° F (-16 ° C) ukuya kwi-225 ° F (107 ° C).
