Polytetrafluoroethene,pfupiso:PTFE
Mazita: PTFE, tetrafluoroethylene, mambo wepurasitiki, F4.
Zvakanakira zvePTFE
PTFEndiyo mapurasitiki einjiniya akakosha, pari zvino ndiyo inodzivirira corrosion, inozivikanwa se "mambo wepurasitiki".Iwo maficha akanyanya uye akadzika tembiricha kuramba, corrosion resistance, high insulation, kuchembera kuramba, self-lubrication.
Inoshandiswa mumhepo, zvemagetsi nemidziyo yemagetsi, indasitiri yemakemikari, michina uye zviridzwa, chikafu uye zvekurapa, pombi, mavharuvhu nemapaipi, mota nengarava, mhepo compressors, nezvimwewo, uye chave chinhu chakakosha pakugadzirisa akawanda akakosha matekinoroji mumazuva ano. industry.
PTFE molecule inert F maatomu anodzivirira uye anodzivirira CC chisungo, uye CF bonding simba inonyanya kugadzikana, iyo molecular cheni inonetsa kuparadzwa, chimiro chakanyatsogadzikana.Ichi chimiro che molecular chinotsanangurawo zvinotevera zvakanakisa zvimiro zvePTFE.
Corrosion resistance:Pamusoro pesimbi dzakanyungudutswa dzealkali uye nezvinonyungudutsa zvishoma zvakaita se-alkane hydrocarbons pamusoro pe300 degrees Celsius, inoshingirira mukuora kwenguva refu nemamwe makemikari.
Kupokana kune tembiricha yakakwira uye yakaderera: inogona kushandiswa kwenguva yakareba pa -60 + 260 ℃.
High lubrication:diki diki coefficient of friction pakati pezvinhu zvakasimba, kunyange ice haigone kuenzaniswa nayo.
Kusanamatira:diki diki tension pakati pezvinhu zvakasimba, hainamati kune chero chinhu.
Weather Resistance:Hupenyu hurefu hwekukwegura pakati pemapurasitiki.
Non-toxicity:izvo zvinhu zvinogona kushandiswa semidziyo yeropa yekugadzira, isiri-chepfu uye isiri-allergic uye mamwe maitiro akashata, echikafu uye mishonga giredhi zvinhu.
Insulating properties:firimu gobvu sepepanhau rinokwana kupikisa magetsi emagetsi e1500V.
Pamusoro pezvo, PTFE hainawo kunyura, kusapisa, uye yakanyanya kuokisijeni, ultraviolet mwenje.
Zvakaipa zvePTFE
Kunyangwe PTFE iine yakanakisa mashandiro ekuita, asi yakaderera mechanical simba, hombe coefficient of linear kuwedzera, kusapfeka zvakanaka kuramba, urombo creep resistance, urombo kupisa conductivity uye zvimwe zvikanganiso.Musimba remagetsi uye mamwe mamiriro akaomarara, sekushandiswa muindasitiri yekuisa chisimbiso yevharuvhu uye muganho wayo chaiwo wekushandiswa kwakachengeteka kwekushisa kazhinji mukati -70 ~ +150 ℃.Kuti ukunde zvikanganiso izvi, PTFE resin inogona kuzadzwa neanosimbisa maajenti ekuvandudza ma mechanika echinyorwa, kuitira kuwedzera chiyero chekushandiswa kwezvinhu zvayo.
Nhanganyaya kune zvivakwa zvemavara PTFE
Rudzi rwekutanga rwePTFE ruchena rwemukaka, nepo runyoro rwePTFE imhaka yekuti PTFE base material yakazadzwa nezvinhu zvekubatsira.Zvishandiso zvekubatsira zvinogona kukamurwa kuita zvikamu zviviri zvinoenderana nekushandiswa: yekuwedzera mumiriri uye ruvara poda mumiriri.
Rudzi rwehupfu mumiriri wekirasi: izere nehupfu hweruvara muPTFE, inogona kuve yakasununguka nhema, yero, tsvuku, girini, bhuruu zvichingodaro.Ruvara poda mumiriri ndeye kushandura chete ruvara rwePTFE, chiyero chekuzadza ishoma saka mhedzisiro yePTFE yekutanga kuita inogona kufuratirwa.Nechepfungwa, mumiriri wehupfu yemuvara unofanirwa kukanganisa kugadzikana kwekemikari yePTFE, kusungirira, kusimba kwesimba uye mamwe ma mechanical properties.Naizvozvo, zvimwe zviitiko zvakakosha zvinoda kuzviziva.Colored PTFE inosangana nezvinodiwa nevatengi vane zvinodiwa zvemavara ekuona.
Kutenga iyo chaiyo PTFE tubing haisi yekungosarudza zvakasiyana siyana zvekushandisa zvakasiyana.Zvimwe kusarudza mugadziri akavimbika.BesteflonFluorine plastic Industry Co., Ltd. inyanzvi mukugadzirwa kwemhando yepamusoroPTFE hosesuye machubhu kwemakore makumi maviri.Kana paine ptfe chubhu mibvunzo uye zvinodiwa, ndapota inzwa wakasununguka kutibvunza kune mamwe mazano ehunyanzvi.
