Ke Kumu Hana a me ka Noi ana i na paipu PFA a me na kookoo welding

I loko o ka ʻoihana ʻenehana hou, ua lilo nā paipu PFA (perfluoroalkoxy resin) a me nā koʻokoʻo kuʻekuʻe like i mea nui i loko o ka chemical, semiconductor, pharmaceutical a me nā ʻoihana ʻē aʻe ma muli o ko lākou kūpaʻa kemika maikaʻi loa, ke kūpaʻa wela kiʻekiʻe a me ka coefficient friction haʻahaʻa. E nānā hohonu kēia ʻatikala i ka loina hana a me nā pono noi o nā paipu PFA a me nā koʻokoʻo welding.

Ke Kumu Hana a me nā ʻano o nā paipu PFA

ʻO nā paipu PFA he paipu fluoroplastic -kiʻekiʻe me kahi ʻano molekala like me PTFE (polytetrafluoroethylene), akā me ka ʻoi aku ka maʻalahi a me ka hana hoʻoponopono. ʻO nā hiʻohiʻona nui o nā paipu PFA:

Ke kū'ē i ka corrosion kemika: He kū'ē ikaika ka PFA i nā meaʻakika ikaika a pau, alkalis ikaika a me nā mea hoʻoheheʻe organik, a he kūpono ia no ka laweʻana i ka media corrosive.

Kū'ē wela ki'eki'e: Hiki ke ho'ohana 'ia ka PFA no ka manawa lō'ihi ma ke ana wela o -200 degere a +260 degere, a 'o ka manawa pōkole -hiki ke kū'ē wela i ka 300 degere, e hālāwai ana i nā koi o nā ka'ina wela ki'eki'e.

ʻO ka pākuʻi haʻahaʻa haʻahaʻa: ʻO ka paia o loko o nā paipu PFA he laumania a he haʻahaʻa loa ka pākuʻi, hiki ke hōʻemi i ka pale ʻana i ka wai a kūpono no ka lawe ʻana i ka wai maʻemaʻe kiʻekiʻe.
ʻO ka insulation uila maikaʻi loa: He ikaika dielectric kiʻekiʻe loa ka PFA a me nā waiwai insulation, a kūpono ia no nā ʻoihana uila a me nā semiconductor.
ʻO ke kumu hana a me ke kaʻina hana hoʻoheheʻe o nā koʻokoʻo wili PFA

ʻO nā koʻokoʻo welding PFA nā mea kūikawā i hoʻohana ʻia e hoʻopili i nā paipu PFA a i ʻole nā ​​​​mea ʻāpana. Hoʻokumu ʻia kā lākou kuʻi ʻana ma luna o ka ʻenehana pili hoʻoheheʻe wela. ʻO nā ʻano hana wiliwili maʻamau ka:

ʻEa wela: Hoʻowela ʻia ke koʻokoʻo wili PFA a me ka paipu i ke ʻano hoʻoheheʻe ʻia i ka manawa like e ka -wela wela kiʻekiʻe, a laila hoʻohana ʻia ke kaomi e hoʻokuʻi iā lākou, a ua hoʻokumu ʻia kahi pilina paʻa ma hope o ka hoʻolili ʻana.
Extrusion welding: Ma hope o ka hoʻoheheʻe ʻia ʻana o ke koʻokoʻo wili PFA e kahi pū wili kūikawā, ʻomi ʻia i ka ʻāpana e wili ʻia e hana i kahi weld like.

ʻO ke kī i ka welding PFA ʻo ia ka mālama ʻana i ka mahana a me ka wikiwiki o ka welding e hōʻoia i ka hoʻoheheʻe ʻana me ka ʻole o nā ʻōpala a i ʻole nā ​​​​mea haumia, e hōʻoiaʻiʻo ai i ka ikaika a me ka lōʻihi.

Nā kahua noi a me nā manaʻo mākeke

Hoʻohana nui ʻia nā paipu PFA a me nā koʻokoʻo welding i nā ʻoihana e like me nā kemika, semiconductor, lāʻau lapaʻau, a me ka hoʻoili ʻana i nā meaʻai, ʻoi aku hoʻi i nā kūlana e koi ʻia ai ka maʻemaʻe kiʻekiʻe, ke kūpaʻa corrosion, a me ke kūpaʻa wela kiʻekiʻe. Me ka piʻi nui ʻana o nā mea hana kiʻekiʻe -ma ka ʻoihana honua, ākea ka manaʻo o ka mākeke no nā paipu PFA a me nā lāʻau wili.

I ka wā e hiki mai ana, me ka holomua o ka ʻepekema waiwai, e hoʻomaikaʻi hou ʻia ka hana o nā paipu PFA a me nā koʻokoʻo welding, e hāʻawi ana i nā hopena hilinaʻi no nā ʻoihana like ʻole.
