Mazuva ano, zvigadzirwa zvakawanda zvinomira pachena mukuvandudza matekinoroji neindasitiri, uye yakanakisa PTFE chubhu ndechimwe chezvigadzirwa izvi zvinoita basa rakakosha munzvimbo dzakasiyana siyana.Asi wakamboona here kuchembera kwePTFE machubhu?Kuita kwePTFE machubhu kuchaderedzwa zvakare mushure mekukwegura.Saka nhevedzano yezviyero inofanirwa kutorwa kudzivirira kuchembera padanho rekupedzisira rekugadzirwa kwePTFE machubhu.Kuchembera kwePTFE machubhu ndekwechisikigo uye hakugone kudzivirirwa, asi chinhu chega chaunogona kuita kunonoka kuchemberaPTFE machubhu.Kuti ubatsire kuderedza kuchembera kwePTFE tubes, unofanirwa kusimbisa kuchengetedza mukushandisa PTFE tubes uye kutora matanho ekudzivirira mamiriro ezvinhu aya.Pano Suko inokupa nzira ina huru dzekudzikisa kuchembera kwePTFE chubhu yako.
1. Pakusarudza saizi zvinhu zvePTFE machubhu, unofanira kushandisa sulfur kurapa hurongwa pose pazvinogoneka.Nekuda kwekupikiswa kwekupisa kwerabha yayo ine vulcanized, inogona kugadziridzwa nekudzikisa kana kudzivirira kushandiswa kwe elemental sulfur, iyo inogona kuderedza kana kubvisa polysulfide crosslinks uye kuburitsa kunyanya monosulfide kana disulfide crosslinks, nokudaro kuderedza kuchembera kwemachubhu e teflon.
2. Kuti ave nechokwadi chokuti zvinhu zvinowana kudiwa kwekupisa, kushandiswa kweperoxide kunodiwa.Muchiitiko ichi, peroxide vulcanization inogadzira kabhoni ine kugadzikana kwekupisa uye kabhoni cross-linking bond.PTFE chubhu inogadzirauyewo inotaura kuti iwe unofanirwa kubhadhara zvakanyanya kune zvimwe zvinowedzera mukushandiswa kweperoxides.Semuenzaniso, kusarudzwa kwema antioxidants kunofanirwa kuve kwakasimba, sezvo mazhinji acho achikanganisa vulcanization yeperoxide.Nokudaro, iwe unogonawo kushandisa mafuta eparafini, chinowedzera chinowedzera chisingazokanganisa peroxide vulcanization.
3. Mukuwedzera, kuitira kudzivirira kuparadzaniswa kweperoxide cation uye kudzivisa vulcanization yakaderera yepamusoro-soro hose (inoratidzwa nekuoma kwakadzika, modulus yakaderera uye kudzvinyirira kwepamusoro uye kushanduka kwenguva refu), unofanira kushandisa peroxide kuderedza. huwandu hwe acidic filler.Kana zvichibvira, kuwedzerwa kwealkaline compounds (eg zinc oxide kana magnesium oxide) kazhinji inovandudza kushanda kwepamuchinjikwa kweperoxide.
4. Paunenge uchigadzira zvakanakisa ptfe tubes, zvimwe zvinowedzera zvinogona kuwedzerwa, zvakadai se antioxidants, uye alkaline compounds, nezvimwewo, kuitira kuti uvandudze kushanda kwepamuchinjikwa kweperoxides uye kunonoka kukwegura kwe teflon tubes.
