Wakambozvibvunza here kuti nei vamwe Machira ePTFE epamusoro-tembiricha calendering - post-sintering maitiro apo inopisa girazi rollers inoshandisa yakakwira mutsara kumanikidza kuumbazve chigadzirwa.
Calendaring inoshandura zvakanyanya microstructure, pamusoro pemamiriro ezvinhu, uye kushanda kwesevhisi kwePTFE high-temperature jira . Inogona kuderedza kushata kwepamusoro nehurongwa hwehukuru, kuvharira mapinikoni madiki, uye nekuvandudza zvinoshamisa zvimiro zvekuburitsa - asi nemubhadharo wekudzikisa simba rekubvarura uye kuchinjika.
Aokai PTFE inoshandisa calendering inosarudza zvichienderana nezvinodiwa zvekushandisa. Ichi chinyorwa chinotsanangura zvishanu zvakakosha mhedzisiro: pamusoro morphology, kuburitsa kuita, kusamira, michina zvimiro, uye dimensional kushivirira.

Chikonzero nei kusunungurwa kuchinatsiridza: Jira risina kusungirirwa rine faibha bundles dzakabudikira dzinogadzira kupindirana kwemichina nezvinonamira, rabha, kana mukanyiwa. Calender inogadzira inoenderera, yekupedzisira-yakapfava PTFE layer. Zvishandiso zvinongobata yakaderera-pasi-simba PTFE - kupepeta zvisingaite pasina kana chasara.
Mhedzisiro yekushandisa: Yakakosha pakuumbwa kwemusanganiswa (inoderedza mitengo yekuramba), rubber vulcanization (inoderedza mold yekuchenesa frequency), kubika chikafu, uye kutakura kwekuchenesa.
Aokai PTFE inopa ese akarenda uye asina uncalendered mavhezheni edu ePTFE machira. Zvekuburitsa liner application uko zero yasara yakakosha, isu tinokurudzira zvakasimba calendered machira. Kune maapplication anoda yakanyanya kubvarura simba (semuenzaniso, mabhandi ekutakurisa ane mupendero kukuvara kwengozi), uncalendered inogona kusarudzwa.

Inosimudza breakdown voltage - yakanakira magetsi ekuisa liner
Yakakosha chenjedzo: Kuwedzeredza-calendering iyo inoderedza zvakanyanya ukobvu hwejira inogona kukanganisa kuita kwese kuvharisa. Kuringana kunodiwa.
Mechanical Properties - Dual Impacts
1. Zvakanaka Migumisiro
Property
Kuvandudza
Pfeka kuramba & fuzz kuramba
Yakavandudzwa zvikuru - yakatsetseka pamusoro inogovera friction stress; fiberglass yakavharirwa zvizere, hapana fuzz kuratidzwa mushure mekudzokorora kukotama
Tensile simba kushandiswa
Kuwedzera zvishoma - compaction inozadza mikaha pakati peshinda, ichigonesa kugovana mitoro; stress concentration pfungwa dzakabviswa
2. Negative Effects
Property
Kudzikisira
Kupfava & kuchinjika
Yakaderedzwa - yakakwirira kuoma; haigoni kumira kukotama kwakapinza. Kupeta kwakapinza kunokonzera mavara machena (mitswe)
kubvarura simba
Kudzikira - kubatanidza kunobvisa nzvimbo inotsvedza pakati peshinda. Kana yatsemuka, kuparadzira kunokurumidza
Elongation panguva yekuzorora
Yakaderera - yakaonda, denser chimiro chinoderedza ductility; kubatwa nekatyamadza kwapera simba
Nhungamiro yekushandisa:
Dzivisa calender ye: Zvigadzirwa pamadiki madiki roller (kazhinji kukotama kubhenda), kupisa kunonamira maoko, simba rekupeta maapplication.
Sarudzo yecalender ye: Kusunungura liner, magetsi ekudzivirira, machira asingadzire, maconveyors emumba akachena (kupfeka kushoma)

Balance wear resistance vs. kubvarura simba
Muchidimbu , calendering inzira ine simba yekumashure-kugadzirisa iyo inosandura PTFE yakakwirira-tembiricha machira. Iyo inoshandura nzvimbo kubva kune textured (Ra 0.5-1.0 μm) kune girazi-kufanana (<0.05 μm), inoshamisa inovandudza kusunungurwa uye kushorwa kwemavara, inovhara pinholes yekusapinda kwepamusoro uye simba re dielectric, uye inosimudzira kupfeka kusagadzikana. Nekudaro, mabhenefiti aya anouya nekutengeserana-offs: kuderedzwa kubvarura simba (25-30% kurasikirwa), kuderera kuchinjika, uye njodzi yekutsemuka pasi pekukotama kwakapinza.
Sarudza calendered PTFE jira rekuburitsa liner, corrosion barriers, magetsi ekudzivirira, uye yekuchenesa maapplication. Sarudza jira risina kukwenenzverwa kana kuti rakareruka kuti rikwanise kubhenda, mabhandi ekutakura ane misodzi akasimba, uye maapplication ayo akapinza akapinza asingadzivisike.
