Polytetrafluorootherylene (PFA) vs. PolytetraFluorootheryle (PTFE)

1. Makemikari Kugadziriswa Kusiyana:

PFA inosanganisira perflueroloKoxy, iyo yakaenzana neyakaenzana maatomu eFlueline muPTFE ichitsiviwa nePerfluoroalisoKoKoxy. Kabhoni yakanamatira yakanangana neokisijeni, uye ipapo oksijeni inosungirirwa kune boka rakadai sePerfluoromtherl kana Perfluoroeth. Kuenzaniswa nePTFE, inoderedza iyo yekunyungudika viscossity uye inofambisa kugadzirisa. Zvimwe zvacho zvakasara zvivakwa ne ptfe haina kusiyana zvakanyanya.

2. Musiyano mukushandisa:

PFA ine zvakafanana zvakanakisa zvivakwa sePTFE, asi zvakare ane termplasticasticasticsity, uye inogona kuva yetemoplastic yakagadziriswa nenzira dzekugadzirisa dzeTermoplastic resins. Iyo inogadzirwa neCoplymermentiz uye Perfluoropropyl vinyl ether mune imwe chikamu mumvura ine perfluorocarcarboylate Izvo hazvina kungoita chete tembiricha yebasa sePTFE, asi zvakare ine simba rekusimba pamakumi maviri nemashanu Iyo ine yakakura yekugadzirisa huwandu uye yakanaka kuumbwa kuita, yakakodzera kumanikidzwa kuumbwa, kubuda, jekiseni kuumba, kuendesa kuumbwa uye kumwe kuumba maitiro. Inogona kushandiswa kugadzira waya uye tambo ichisimbisa Shehati, yakakwira-freetency uye Ultra-yakakwira-kuwanda-kupokana nemapipi emakemikari, mavhavha uye mapombi; Nzvimbo dzakasarudzika dzeshandirapamwe yemishinari, zvisikwa zvakasiyana-siyana zvefungidziro zveiyo indasitiri yechiedza, uye polytetrafluoroleyleyley antiicorrosivery, uye mamwe matanda anotyisa. Iyo inogadzirwa nekudzora funcible ptfees granules, nechitarisiko cheSiMi-Likel Milky White, Smooth Yakatsiga, Dense uye Yunifomu Cross-Chikamu. Iyo inoshandiswa zvakanyanya mulating yePTFE ndiro uye pombi, kuitira kuti ptfe Kupararira kwemvura kunowanikwa nekuwedzera emulsifier kune iyo Coplymer yakawanikwa neCopolymensiazation's yePTFE uye PERFLOWORPROPLELL VINITL Ether, uye yakabva yanyudzwa pane imwe tembiricha. Iyo yakasimba zvirimo ndeye 30% × 1%. Chitarisiko chakachena Milky White kana Chiedza chellow Translucent. Iyo ine dzakasiyana siyana dzimba dzakanaka dzePTFE PTFE Resin. Inogona kushandiswa kwenguva yakareba muna 260 ℃, uye ine anti-anomisheni, kurwisa, kupora, kusarudzika, uye inoshandiswa mune yakakura kambani kambani uye indasitiri yechikafu Anti-anomamatira, Anti-Corrosion Zvigadzirwa.

PTFE - PolytetraFluoroHery inogadzirwa nePolymerization yeTetrafluorolerylene Monomer nekumiswa nzira. Molecular uremu = 5.2 Harsional dentity 2.1-2.3, Refractive Index 1.37, girazi rinoshandura tembiricha 327 ℃, afrul Decomposition tembiricha Mune 400 ℃ pamusoro pekutsvaga kwekurema uremu uye kuora kwemagasi ane chepfu. Shandisa tembiricha -250 ~ 260 ℃, muna 210 × ushandise kusvika zviuru gumi zve h. Kunaka kwemakemikari kurwisa, kurwisa kune chero yakasimba acid (kusanganisira aqua regalia), yakasimba alkali, mafuta, kushayiwa kwemvura, yakaderera yekukakavara, yakanakisa kuramba uye kuzvishingisa. Kupokana kwakanaka kwazvo. Zvakanakisa zvemagetsi zvemagetsi, zvakanaka arc kuramba. Asiri-inonamira, anenge zvese zvinomiririra zvinhu hazvigone kuomerera kune yayo, zvachose isingaonekwe. Ine zita rekuti "mambo wepurasitiki". Tensile Simba (MPA)> 23 ELOLOLETION (%)> 250.

3. Kugadzirisa Misiyano:

Musiyano mukuru mukugadzirisa ndewekuti PFA inogona kupisa jekiseni jekiseni kuumbwa, nepo ptfe isingakwanisi kupisa jekiseni kuumba.

Iyo iri pamusoro ndeye sumo kumisiyano pakati pePFA uye PTFE zvinhu .

Kwenguva yakareba, ptfe yakatsvakwa neindasitiri nekuda kweiyo yepamusoro uye yemakemikari zvivakwa. Nekudaro, izvo zvisingakwanisi nzira dzekugadzirisa dzaro dzakonzera masayendisiti mazhinji uye mainjiniya kuti vatambure zvakawanda. Pakupedzisira, mushure mekutanga kwePFA kumusika, vakagamuchira iyo plastic indasitiri itsva yakatsvaga-mushure. Izvi zvinyorwa, nezvivakwa zvakafanana neiya yePTFE, ine zvinhu zvakanakisa zvekugadzirisa, nekudaro kugadzirisa matambudziko einjiniya.
