High pressure teflon hose imatha kupirira kutentha kwambiri?

The mkulu-anzanu teflon payipi akhoza kupirira kutentha, angati madigiri, makamaka zimadalira makhalidwe ake enieni zakuthupi, makulidwe, ntchito zachilengedwe ndi zotheka pamwamba mankhwala ndi zinthu zina.

Mkulu kutentha kugonjetsedwa osiyanasiyana

1. General kuchuluka:

Nthawi zambiri, payipi ya teflon yothamanga kwambiri imatha kupirira kutentha kwanthawi yayitali pafupifupi madigiri 260.

Pansi pa kutentha kwanthawi yomweyo, kutentha kwake kumatha kufika madigiri 400.

2. Mikhalidwe yapadera

Muzochitika zina zapadera, monga kuthamanga kwapansi ndi kuthamanga kwa mpweya wochepa, kutentha kwa kutentha kwa teflon hose kungakhale kokwera, mpaka 300 ° C.

Makhalidwe akuthupi

Ma hoses a teflon othamanga kwambiri amapangidwa makamaka ndi zida za polytetrafluoroethylene (PTFE), zomwe zimakhala ndi kutentha kwambiri. PTFE ndi mankhwala khola, amatha kulekerera zidulo amphamvu (kuphatikizapo aqua regia) , oxidants amphamvu, kuchepetsa wothandizila ndi zosiyanasiyana zosungunulira organic kupatula zitsulo zamchere, fluorinated TV ndi sodium hydroxide pamwamba 300 ° C. High-pressure teflon hose alinso makhalidwe kukana kuvala ndi kudzipaka mafuta, kutsika kwapakati, komwe kumapangitsa kukhala m'malo osiyanasiyana ovuta kukhalabe ndi khola logwira ntchito.

Zochitika zantchito

High-pressure teflon hose imagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, ma pharmacy, kukonza chakudya ndi mafakitale ena chifukwa cha kutentha kwambiri, kutentha kochepa komanso kukana kwa dzimbiri. M'makampani opanga mankhwala, amatha kunyamula mitundu yonse yamankhwala; m'makampani opanga mankhwala, amatha kuonetsetsa kuti pamakhala malo oyendera audongo komanso osabala; m'munda wokonza chakudya, ungathenso kutsimikizira chitetezo cha chakudya ndi ukhondo.

Mfundo zofunika kuzikumbukira

1. Kukula kwa kutentha ndi kutsika: ngakhale payipi ya teflon yothamanga kwambiri imatha kupirira kutentha kwa -190 madigiri, koma kugwiritsa ntchito kutentha kwambiri, kufunikira koganizira kukula kwa matenthedwe ndi kuchepa kwa ntchito ya payipi. Nthawi zambiri otetezeka ndi ogwira malire ntchito kutentha tikulimbikitsidwa mozungulira -70 madigiri.

2. Kuchepetsa kupanikizika: kuwonjezera pa kukana kutentha kwapamwamba, payipi ya teflon yothamanga kwambiri imathanso kupirira kuthamanga kwambiri (monga za 100 bar) , koma muzogwiritsira ntchito zofunikira ziyenera kusankha zofunikira za payipi ndi zitsanzo malinga ndi zikhalidwe zina.

Mkulu-anzanu teflon payipi mu zinthu zabwinobwino kupirira mosalekeza mkulu kutentha pafupifupi 260 madigiri, yomweyo kutentha akhoza kufika madigiri 400. Nthawi zina, kutentha kwake kumakhala kokwera kwambiri. Komabe, pogwiritsira ntchito kufunikira kosamalira kuwonjezereka kwa kutentha ndi kutsika kwa zotsatira za kupanikizika ndi zinthu zina.
