Mazuva ano, zvigadzirwa zvakawanda zvinoonekwa zvakanyanya mukuvandudzwa kwetekinoroji nemaindasitiri, uye PTFE chubhu ndeimwe yezvigadzirwa izvi zvine basa rakakosha muminda yakasiyana-siyana. Asi wakamboona here kukwegura kweMachubhu ePTFEKushanda kwemachubhu ePTFE kuchadzikirawo mushure mekukwegura. Saka matanho akatevedzana anofanira kutorwa kudzivirira kukwegura padanho rekupedzisira rekugadzirwa kwemachubhu ePTFE. Kukwegura kwemachubhu ePTFE kwakasikwa uye hakugone kudzivirirwa, asi chinhu chega chaunogona kuita kunonotsa kukurumidza kwekukwegura kwe Machubhu ePTFE. Kuti uderedze kukwegura kwemachubhu ePTFE, unofanira kusimbisa kuchengetedza machubhu ePTFE uye kutora matanho ekudzivirira mamiriro aya.Besteflon Inokupa nzira ina huru dzekudzikisa kukwegura kwechubhu yako yePTFE.
1. Pakusarudza saizi yezvinhu zvePTFE tubes, unofanirwa kushandisa sulfur curing system pese pazvinogoneka. Nekuda kwekusapisa kwerabha yayo yakanyungudutswa, inogona kuchinjwa nekuderedza kana kudzivirira kushandiswa kwe elemental sulfur, iyo inogona kuderedza kana kubvisa polysulfide crosslinks uye kugadzira monosulfide kana disulfide crosslinks, nokudaro ichideredza kukwegura kwePTFE machubhu.
2. Kuti zvive nechokwadi chekuti chinhu chacho chinosvika pakudzivirira kupisa kwaunoda, kushandiswa kweperoxide kunodiwa. Muchiitiko ichi, peroxide vulcanization inogadzira kabhoni ine kugadzikana kuri nani kwekupisa uye carbon cross-linking bonds.
Mugadziri wemachubhu ePTFE anotiwo unofanira kunyatsoteerera zvimwe zvinowedzerwa pakushandisa peroxides. Semuenzaniso, sarudzo yema antioxidants inofanira kuomeswa zvakanyanya, sezvo akawanda acho achikanganisa vulcanization yeperoxides. Saka, unogona zvakare kushandisa paraffin oil, chinowedzera chinoshanda chisingazokanganisa vulcanization yeperoxide.
3. Pamusoro pezvo, kuti udzivise kupatsanurwa kwe peroxide cation uye kudzivirira kuputsika kwakanyanya kwehosipu ine pressure yakakwira (zvinoratidzwa nekuomarara kwakaderera, modulus yakaderera uye kudzvanywa kwakanyanya uye kushanduka kwenguva refu), unofanirwa kushandisa peroxide kuderedza huwandu hwe acidic filler. Kana zvichibvira, kuwedzerwa kwe alkaline compounds (semuenzaniso zinc oxide kana magnesium oxide) kunowanzo vandudza kushanda kwe cross-linking kwe peroxide.
4. PakugadziraPTFE machubhu, zvimwe zvinowedzerwa zvinogona kuwedzerwa, zvakaita sema antioxidants, uye alkaline compounds, nezvimwewo, kuitira kuvandudza kushanda kwe peroxides uye kunonotsa kukwegura kwePTFE machubhu.
