Pae leki Information

Ka pae ka leki i hoʻohana i ka sila, lubricate, a me ka pale 'ana ma luna o wili hoʻopaʻa i, i paukūʻia, a me ka pono. Ka mea, i mau haawiia i like:

  • Teflon lola
  • PTFE lola
  • PTFE ka pae o ka wepa lola
  • plumber ka leki

Ka pae leki i ana i ka polytetrafluoroethylene (PTFE), he hoomaikai mea pōaka, perfluorinated pīlali i ua maikaʻi ikeia ma kona DuPont momoku ahi, a kakau kope '-Teflon. PTFE leki i ka loa haahaa kaʻi lau waiwai o ke kū'ē, maikai Nine Inch ia'ku, a ua maikai ka wela e kū'ē'ē mai. Nine inertness ua ālai 'kea-e kuhikuhi ana, a me ka PTFE ka pae leki maikai ke koho no ka palapala noi i Komo corrosive Nine Inch e like me ke kinowai ai oxygen, a caustics e like me'amoniuma hydroxide. Ka pae leki i hiki e i ka polyethylene (PE), he haʻahaʻa-kāki ea e ia kaua ke pale i ka wai, a he nui Nine Inch.

hoakaka

Ka pae leki lawe hoakaka e like me:

  • pa apŘ
  • tensile ikaika
  • elongation
  • Ana
  • kūpapakū hoʻokaulike

PTFE ka pae leki mai ana e wehewehe i ko lakou mau huahana like kekahi kiʻekiʻe-pa apŘ a haʻahaʻa-pa apŘ. High-pa apŘ PTFE ka pae leki pele i ka pa apŘ o .70 g. / Cm3 paha 1,2 g. / Cm3. Low-pa apŘ PTFE ka pae leki pele i ka pa apŘ o .37 g. / Cm3. Tensile ka ikaika o ka poe koi 'ia e uhai i kekahi'āpana o ka pae leki ma ka huki ana i ke alo welau. Elongation o ka fractional ulu i loko o ka pae leki ka lōʻihi ma muli o ke stress ma ka hoʻopilikia 'ole i ka thermal? Anoe? Aiey. Nui Ana no ka pae leki nā loa, ka laula, a me ka mānoanoa. Me ka pili ana i ka kūpapakū hoʻokaulike, e hoʻololi i kekahi Teflon leki i hoʻohana me nāʻohe, paipu, a me kahawai ana i hanaʻi i ka Aluminum, eleele hao, a me ke keleawe. Other PTFE ka pae o ka wepa leki hanohano malaila i ka chrome, keleawe, aniani, ea, a me ka laholio.

Standards

PTFE ka pae leki ma hope mau hoʻokumu paʻa ka pono mau hae, a ua ano-kivila mai no keʻano o ke noi. MIL-T-27730A mea he US koa hoakaka (MIL-SPEC) i hoʻomōakaaka i ka palena iki mānoanoa o 3 mils. AA-58092 mea he kalepa hae e malama i ka mānoanoa koi o MIL-T-27730A, akā, kō ka palena iki pa apŘ hae. White PTFE ka pae leki hoʻolako pilipaa sila no keʻano o ka wili ami a me ka mea pono no ka hapanui palama, a potable wai nenoai. Yellow PTFE ka pae leki ua mea i hoʻohana 'ia me nāʻohe, kahawai ana i hanaʻi, hoʻopaʻa, kiwikā, a wili kinoea laina e lawe lewa, ammonia, butane, chlorine, a me hydrogen. Pink Teflon leki ua i ke kaumaha-hana, hanalima papa PTFE, a ua hoʻohana 'ia i loko o kalepa paha hanalima palama noi. Green Teflon ka pae leki i ke hoʻohana 'ia ma o oxygen-me ke kanaka ole noi.
