Chiyambi cha ptfe kutentha kuotcha chubu

M'moyo wamasiku ano,ptfe kutentha kuchepetsa chubuyakhala ikugwiritsidwa ntchito kwambiri poteteza chitetezo cha ma waya osiyanasiyana, ma solder, ma inductors, dzimbiri komanso kupewa dzimbiri kwa machubu achitsulo ndi ndodo.Lero, tiyeni tikambirane nanu zimene tiyenera kulabadira ntchito ptfe kutentha shrink chubu?

Choyamba, kulabadira ptfe kutentha kuotcha chubu kusankha zolakwa: ptfe kutentha kuotcha chubu ali osiyana kutentha shrinkage multipliers, ptfe kutentha kuotcha chubu specifications zambiri mankhwala a pazipita awiri m'mimba mwake amaloledwa pambuyo shrinkage wa casing ndi shrinkage multiplier.Ndiye tiyenera kutsatira mfundo ya m'mimba mwake wa m'mimba mwake wa malaya thupi pamaso shrinkage, komanso m'mimba mwake wa m'mimba mwake chinthu m'manja pambuyo shrinkage, posankha mtundu.

Chachiwiri, tcherani khutuptfe kutentha-shrinkable chubuManja chinthu m'mphepete ndi lakuthwa kwambiri: pamene ife kudula chubu, odulidwa si lathyathyathya, kapena akupera si yosalala adzatsogolera ptfe kutentha-shrinkable chubu ntchito ndondomeko akulimbana.

Chachitatu, tcheru kwambiri ptfe kutentha kuotcha chubu Kutentha kutentha kwambiri kuposaptfe kutentha kuotcha chubukutentha kwa shrinkage: nthawi zambiri timagwiritsa ntchito kutenthetsa ptfe kutentha shrink chubu ndi: kutentha mfuti, kuwala, uvuni.Kutentha mfuti ndi akatswiri chida kutentha ptfe kutentha kuotcha chubu, ambiri ntchito kutentha mfuti kutentha akhoza kufika madigiri 400, ndiye ife ntchito kutentha mfuti, kulabadira nthawi kupitiriza kutembenuza kutentha mfuti, kuti ptfe kutentha kuotcha chubu chonse. kutentha kuonetsetsa kuti ptfe kutentha shrinkage chubu shrinkage pambuyo mawonekedwe.Wopepuka ndi chida chathu yabwino ndi ambiri ntchito kutenthetsa ptfe kutentha shrink chubu, koma kutentha kwake ndi mpaka zikwi za madigiri, kwambiri kuposa kutentha shrinkage wa ptfe kutentha kuotcha chubu, ndiye tiyenera kulabadira kusuntha mmbuyo ndi mtsogolo pamene ntchito chopepuka kupanga ptfe kutentha kuotcha chubu wonse kutentha wogawana kuteteza moto ptfe kutentha kuotcha chubu pa nthawi yomweyo sapanga mawonekedwe a ptfe kutentha kuotcha chubu kukhala wonyansa kwambiri.Uvuni ndi chida kutenthetsa ptfe kutentha kuotcha chubu, yachibadwa shrinkage kutentha kwa ptfe kutentha shrink chubu ndi 125 ± 5 °, mu apamwamba kuposa kutentha, ngati chisakanizo cha kusakhazikika ptfe kutentha kuotcha chubu anaika mu uvuni shrinkage, mwina kubala mgwirizano kumamatira pamodzi, chifukwa mu dzenje mankhwala, ndiye tiyenera kulabadira makonzedwe yunifolomu, sangathe zakhala zikuzunza m'miyoyo pamodzi.
