Nsalu Yopanda Ulusi ya PTFE

I. Zinthu Zazikulu za Nsalu Yosalukidwa ya PTFE: "Mfumu Yotsutsa Nyengo" M'malo Ovuta Kwambiri

Nsalu ya PTFE yosalukidwa, yodalira ubwino wa zinthu za PTFE ndi makhalidwe a njira ya spunlace, imapanga zinthu zitatu zazikulu, zomwe zimadutsa malire a magwiridwe antchito a ulusi wachilengedwe ndi wosapangidwa m'malo owononga kwambiri, kutentha kwambiri komanso ukhondo wapamwamba:

1. Kukana dzimbiri ndi kutentha: "Chida chosasweka" cha zida zolimba

Kukana dzimbiri kumaposa kwambiri zinthu zonse Mosiyana ndi aramid (yolimbana ndi ma acid ndi ma alkali ena) ndi basalt (yolimbana ndi ma acid ndi ma alkali amphamvu koma yoopa fluoride), PTFE ilibe mphamvu yochita zinthu zonse zodziwika bwino (kuphatikizapo aqua regia, nitric acid yokhazikika, hydrofluoric acid, ndi ma oxidant amphamvu). Pambuyo poviika m'madzi kwa masiku 100, mphamvu yotayika ya kusweka kwake ndi ≤1%. Muzochitika zowononga kwambiri monga chemical engineering, electroplating, ndi pharmaceuticals, nthawi yake yogwira ntchito imatha kufika zaka zoposa 10. Ndi nthawi 5 mpaka 8 kuposa zinthu zachikhalidwe zosagwirizana ndi dzimbiri.

Kutentha kwakukulu kumakhala kokhazikika popanda kuchepetsedwa. Imatha kugwira ntchito mokhazikika kwa nthawi yayitali mkati mwa -200 ℃ (kutentha kotsika kwambiri) mpaka 260 ℃ (kutentha kwakukulu), ndipo imatha kupirira kutentha kwakanthawi kochepa mpaka 300 ℃. Ngakhale itatha kulimbitsa spunlace, imasungabe kukana kutentha koyambirira kwa zinthuzo, kuthetsa mavuto a ulusi wachilengedwe (monga polyester ndi polypropylene) womwe umasungunuka kutentha kwambiri ndipo ulusi wosapangidwa (monga basalt) womwe umasweka kutentha kochepa. Ndi yoyenera pazochitika zotentha kwambiri monga madera ozizira kwambiri komanso mafakitale otentha kwambiri.​

2. Kusamamatira komanso kuletsa kuipitsa + kukangana kochepa: "Chiwerengero chodziyeretsa" m'malo oyera

Kapangidwe ka pamwamba pa PTFE kosamamatira ndi kapadera: Mphamvu ya PTFE yopanda pamwamba ndi yotsika kwambiri (18mN/m yokha), ndipo siimamatirira ku zinthu zilizonse (kuphatikizapo madontho a mafuta, ma resin, ndi zakumwa zokhuthala). Madontho amatha kuchotsedwa mosavuta popanda kutsukidwa pafupipafupi, zomwe zimathandiza kuti nsalu zachikhalidwe zosaluka zikhale "zosavuta kumamatira komanso zovuta kuyeretsa". Ndi yoyenera makamaka pazinthu zomwe zimamatira, monga kukonza chakudya ndi kusindikiza.

Kuchepa kwa kupsinjika ndi kutayika kochepa: Ndi kuchepera kwa kupsinjika kwa 0.04 yokha (dynamic friction coefficient), ndiye wotsika kwambiri pakati pa zinthu zolimba zodziwika. Kuchuluka kwa kusweka kumakhala kochepa kwambiri mukakhudzana ndi zinthu zina. Muzochitika za kupsinjika kwa pafupipafupi monga malamba otumizira ndi zisindikizo, kulimba kwake kumakhala kopitilira nthawi 10 kuposa kwa zida za nayiloni ndi polyurethane, zomwe zimachepetsa kwambiri ndalama zosweka za zida.

3. Kuyeretsa Kwambiri + Kusinthasintha: "Maziko Osinthira" a Kusintha Kwapamwamba

Ukhondo wamkati wopanda kusamuka: Zipangizo za PTFE zilibe zowonjezera (monga mapulasitiki ndi zokhazikika). Pa kutentha kwambiri komanso kuthamanga kwambiri, palibe zinthu zoopsa zomwe zimasamuka, ndipo sizipanga fumbi kapena ulusi wokha. Zimakwaniritsa zofunikira zaukhondo wapamwamba monga kukhudzana ndi chakudya (FDA certification) ndi kusabala kwachipatala (miyezo ya GMP), zomwe zimapangitsa kuti ikhale chinthu choyera chomwe chimakonda kwambiri m'magawo a semiconductor ndi mankhwala.

Njira yopangira spunlace imasunga kusinthasintha: Pogwiritsa ntchito njira yolumikizira madzi yothamanga kwambiri, imapewa kuwonongeka kwa ulusi chifukwa cha njira yopangira singano. Chogulitsachi sichimangokhala cholimba ngati PTFE komanso chimasunga mawonekedwe ake ofewa komanso opindika. Chitha kudulidwa, kusokedwa, ndikukanikizidwa ndi kutentha mu mawonekedwe aliwonse (monga kutseka ma gasket ndi matumba osefera), kuthetsa malire a mbale za PTFE kukhala "zolimba, zosweka komanso zovuta kuzikonza", ndipo ndizoyenera zosowa zosiyanasiyana zosintha.
