Tsananguro yezviratidziro zvekuyedza zvePTFE zvigadzirwa

Kune gumi zvakajairika anti-corrosion zvinhu, uye zvinotevera zvinosuma yavo inoshanda midhiya uye maficha:

1. Polytetrafluoroethylene PTFE (F4)

1. Inoshandiswa pakati: asidhi yakasimba, alkali yakasimba, yakasimba oxidant, organic solvent, etc. Kushanda tembiricha: ≤180°C

2. Zvimiro: Yakanakisa kugadzikana kwemakemikari, kupisa kwakanyanya uye kusagadzikana kwechando;low friction coefficient, yakanakisa self-lubricating material, yakashata fluidity uye yakakura kupisa kwekuwedzera.Hunhu hwayo hwakasiyana-siyana husingasviki kune zvimwe zvinhu, saka PTFE inozivikanwa se "mambo wepurasitiki" uye ndiyo inonyanya kurwisa corrosion pasi rose nhasi.

2. Soluble polytetrafluoroethylene (PFA)

1. Inoshandiswa pakati: asidhi yakasimba, alkali yakasimba, yakasimba oxidant, organic solvent, etc. Kushanda tembiricha: ≤180°C

2. Zvimiro: Irwo rudzi rutsva rwefluorine-ine resin yakafanana neF46.Itsva yakasiyana-siyana yakagadziridzwa kuti ikunde kuoma kwekugadzirisa nekugadzira polytetrafluoroethylene, uye inochengetedza zvakakwana kushanda kwakanaka kwe polytetrafluoroethylene.Yakanaka michina uye yemagetsi ekudzivirira zvivakwa, yakasarudzika kupisa kupisa uye yakaderera friction coefficient, murazvo unodzosa, utsi hwakadzikira uye kunaka kwemamiriro ekunze.Kubatsira kukuru ndeyekuti zviri nyore kuumba.

3. Polyperfluoroethylene propylene FEP (F46)

1. Inoshandiswa svikiro: chero organic solvent kana reagent, dilute kana inorganic acid, doro, ketone, anonhuwirira hydrocarbon, chlorinated hydrocarbon, etc. Kushanda tembiricha: ≤180°C

2. Zvimiro: Iyo mechanics, zvivakwa zvemagetsi uye kugadzikana kwemakemikari zvakangofanana neaya eF4, asi chakanyanya kunaka ndechekuti kuomarara kwacho kwakakwira, kunyangwe kana sampu inomhanyiswa ichimhanyiswa isingaperi, ine yakanakisa kupikisa kwemamiriro ekunze uye nemwaranzi, uye iri nyore kugadzira uye kugadzirisa.Iyo fluorine-ine resin yakagadzirwa kuti ikunde kuoma mukugadzira polytetrafluoroethylene.Pamusoro pekushandisa tembiricha yakaderera pane F4, inochengetedza yakanakisa zvimiro zve polytetrafluoroethylene.

4. Polychlorotrifluoroethylene PCTFE (F3)

1. Inoshandiswa svikiro: zvakasiyana-siyana organic solvents, inorganic etching liquids (oxidizing acids).Kushanda tembiricha: ≤120°C

2. Zvimiro: kupikisa kupisa, magetsi emagetsi uye kugadzikana kwemakemikari ndeyechipiri chete kune F4, simba remagetsi, creep resistance, kuoma kuri nani kupfuura F4.

5, polyvinylidene fluoride PVDF (F2)

1. Inoshandiswa svikiro: inopesana nemakemikari akawanda uye zvinonyungudutsa.Kushanda tembiricha: ≤120°C

2. Zvimiro: Kusimba kwesimba uye kusimba kwesimba zviri nani pane F4, kukotama kwakanaka uye kutonhora kuyerera kupikisa;mamiriro ekunze kuramba, nemwaranzi kuramba, chiedza kuramba uye Anti-kuchembera, etc. The chikuru chinhu adhesion yakasimba, kunaka kuoma uye nyore kuumba.

6, yakagadziridzwa polypropylene (GXPP)

1. Inoshandiswa svikiro: mushonga usingawanzoitiki kana wakanyatsogadziriswa wemushonga une aqueous weinorganic munyu, inorganic acid kana alkali.Kushanda tembiricha: ≤100°C

2. Zvimiro: Ndiyo imwe yemapurasitiki akareruka.Goho rayo, kusimba uye kumanikidza simba uye kuoma kuri nani pane yakaderera-kumanikidza polyethylene.Iine kusimba kwakatanhamara, yakanaka kupisa kupisa, kuumba nyore uye mutengo wakaderera.Mushure mekugadzirisa, maitiro, fluidity, uye flexural modulus ye elasticity inovandudzwa.

7. Yakagadziriswa polyolefin (GXPO)

1. Inoshandiswa svikiro: zvakasiyana-siyana zveasidhi uye alkali munyu uye mamwe organic solvents.Kushanda tembiricha: ≤110°C

2. Ndiyo yakanyanya kunaka-yemhando yepamusoro zvinhu munyika ye-anti-corrosion, anti-static, non-chepfu uye yakakwirira-simba.Yakave yakashandiswa zvakanyanya mumichina mikuru inotenderera uye mavharuvhu nemapombi ekuisa.Inoshandiswa zvakanyanya mumakemikari, metallurgical, chikafu, chekufambisa, mishonga, machira uye mamwe maindasitiri.

8, polyvinyl chloride (yakaoma) PVC

1. Inoshandiswa svikiro: mvura inodzivirira, yakadzika alkali, isiri-oxidizing asidhi, cheni hydrocarbon, mafuta uye ozone.Kushanda tembiricha: ≤60°C

.

9. Ultra yakakwirira molecular uremu polyethylene (UHMW-PE)

1. Inoshandiswa svikiro: Inogona kuramba zvakasiyana-siyana zvinoparadza media (kunze kweasidhi, alkali, munyu, asi oxidizing acid) uye organic solvents.Kushanda tembiricha: ≤100°C

2. Zvimiro: zvakatanhamara kupfeka kuramba, yakaderera friction coefficient uye self-lubricating;yakanakisa kushushikana kutsemuka kuramba, yakanyanya tembiricha inokambaira kuramba uye yakaderera tembiricha kuramba;yakanakisa tensile simba, yakanyanya high simba simba.Yakanakisa kugadzikana kwemakemikari uye kusagadzikana kuneta;hapana adsorption pamusoro, yakanakisa magetsi ekudzivirira;hapana kushanda kwakazara sekusina-chepfu.

10, FRP (phenolic) FRP

1. Inoshandiswa svikiro: organic solvent, kupisa kupisa mafuta, acid uye brine.Kushanda tembiricha: ≤120°C
