Uea uwea PFA

ʻElua Loa o ka ʻinoʻino a me ka wela, ka lōʻihi-paʻa paʻa i nā kaiapuni kiʻekiʻe.: Hoʻohui nā uea kuʻi PFA i ka inertness kemika PTFE me ka weldability hoʻololi copolymer, e hāʻawi ana i ke kūpaʻa ākea i nā waikawa ikaika, alkalis, a me nā mea hoʻoheheʻe organik, me ka 20 × ʻoi aku ka lōʻihi o ke ola ma mua o nā uea metala maʻamau i nā noi kemika. ʻO ka laulā wela loa (-80 degere a i +260 degere) ʻaʻole ia e ʻeha a māhā paha, kūpono i nā ʻōnaehana naikokene wai i nā mea hana sterilization wela wela, e hoʻoholo pono i nā pilikia leaka ʻino ma nā welds.

Hoʻopaʻa ʻia ka ikaika kiʻekiʻe no ka leaka ʻole: Optimized melt fluidity achieves welding strength >90% o nā mea kumu, ʻaʻohe pores a i ʻole nā ​​ʻūhā anu ma hope o ke kuʻi ʻana. Hoʻohuiʻia me nā kaʻina hana cone/flat welding, leakage rate ma lalo o 1 × 10⁻⁹ Pa·m³/s, e like me ka hana hoʻopaʻa ʻana o nā hale i hoʻohui ʻia.

Hoʻololi -Scenario Adaptation, Hana Pono a mālama pono: Hoʻohālikelike me nā paipu PFA / PTFE a me ka reactor welding, e kākoʻo ana i nā kaʻina hana hoʻoheheʻe wela / wela me ka ʻole o nā lako kūikawā. Loaʻa i 7-makahiki leak-ka hana manuahi ma nā ʻōnaehana semiconductor kiʻekiʻe-maʻemaʻe me 85% hoʻemi ʻia ke alapine mālama - "ikaika kiʻekiʻe + pale ʻino/wela + hana maʻalahi" ʻo ia ka mea i koho maikaʻi ʻia no ka wili ʻoihana.

Nā huahana pale: PFA welding wires, Kina PFA welding wires mea hana, mea hoʻolako, hale hana
