Chii chinonzi PTFE?
Polytetrafluoroethylene (PTFE) imhando yepolymer yakagadziriswa ine tetrafluoroethylene semonomer.Iine kupisa kwakanyanya uye kutonhora kwekudzivirira uye inogona kushandiswa kwenguva yakareba paminus 180 ~ 260 º C. Nyaya iyi ine maitiro ekudzivirira asidi, alkali resistance uye kuramba kune zvakasiyana-siyana zvinonyungudutsa zvehupenyu, uye inenge isinganyunguriki mune zvose zvinonyungudutsa.Panguva imwecheteyo, polytetrafluoroethylene ine hunhu hwekupikiswa kwekushisa kwepamusoro, uye friction coefficient yakaderera zvakanyanya, saka inogona kushandiswa pakuzora, uye zvakare inove yakakwenenzverwa kuchenesa kwemukati wemukati wepombi dzemvura.PTFE inoreva kuwedzera kwePTFE coating lining mukati meiyo yakajairwa EPDM rubber joint, iyo inonyanya kuchena.
Basa rePTFE
PTFE inogona kunyatso chengetedza majoini erabha kubva kune yakasimba asidhi, yakasimba alkali kana yakakwirira tembiricha mafuta uye kumwe kusvibiswa kwe media.
Chinangwa
- Inoshandiswa muindasitiri yemagetsi uye seye insulation layer, corrosion inodzivirira uye isingapfekere zvinhu zvesimba uye mitsara yemasaini mune aerospace, avhiyesheni, zvemagetsi, zviridzwa, komputa uye mamwe maindasitiri.Inogona kushandiswa kugadzira mafirimu, mashizha echubhu, tsvimbo, mabearings, gaskets, mavharuvhu, makemikari pombi, pombi fittings, mudziyo mudziyo linings, etc.
- Inoshandiswa muminda yemidziyo yemagetsi, indasitiri yemakemikari, ndege, michina uye mamwe minda kutsiva quartz glassware ye Ultra-yakachena kemikari yekuongorora uye kuchengetedza akasiyana acids, alkali uye organic zvinonyungudutsa mumunda weatomu simba, mushonga, semiconductor. nemamwe maindasitiri.Inogona kugadzirwa kuita yakakwira yekuvharisa magetsi emagetsi, yakakwira frequency waya uye tambo sheaths, corrosion resistant chemical midziyo, tembiricha inodzivirira pombi dzemafuta, nhengo dzekugadzira, etc. Inogona kushandiswa sekuwedzera kwepurasitiki, rabha, machira, ingi, mafuta ekuzora, magirisi, nezvimwewo.
- PTFE inoshingirira pakupisa kwepamusoro uye kukora, ine magetsi ekudzivirira akanakisa, kuramba kuchembera, kunyura kwemvura kwakadzika, uye kuita kwakanakisa kwekuzora.Ihupfu hwepasi rose hwekuzora hwakakodzera midhiya yakasiyana-siyana, uye inogona kukurumidza kuvharwa kuti iite firimu rakaoma, rinogona kushandiswa sechinotsiva graphite, molybdenum uye mamwe mafuta ekuzora.Iyo inoburitsa mumiriri wakakodzera thermoplastic uye thermosetting polymers, ine yakanakisa kubereka kugona.Iyo inoshandiswa zvakanyanya mu elastomer uye rubber indasitiri uye mukudzivirira ngura.
- Sekuzadza kwe epoxy resin, inogona kuvandudza abrasion kuramba, kupisa kupisa uye corrosion resistance ye epoxy adhesive.
- Inonyanya kushandiswa sebinder uye filler yehupfu.
Zvakanakira zvePTFE
- High tembiricha kuramba - kushanda tembiricha kusvika 250 ℃
- Kudzikira kwekushisa kwepasi - kusimba kwakanaka kwemagetsi;Kunyangwe tembiricha ikadonha kusvika -196 ℃, kureba kwe5% kunogona kuchengetedzwa.
- Corrosion resistance - kune akawanda makemikari uye zvinonyungudutsa, inert uye inopesana neakasimba acids uye alkalis, mvura uye akasiyana organic solvents.
- Kuramba kwemamiriro ekunze - kune hupenyu hwakanakisa hwekukwegura hwemapurasitiki.
- High lubrication ndiyo yakaderera friction coefficient pakati pezvinhu zvakasimba.
- Kusina-kunamatira - ndiko kuderera kwepamusoro-soro muhutano hwakasimba uye hahunamati kune chero chinhu.
- Non-chepfu - Iine physiological inertia, uye haina maitiro akashata mushure mekugara kwenguva refu semitsipa yeropa uye nhengo.
- Kuiswa kwemagetsi - kunogona kumira 1500 V yakakwira voltage.
