Hoʻokumu ʻia ʻo Fluoroelastomer ma kāna mau ahi ahi maikaʻi loa, ʻoi aku ka maikaʻi o ka ea, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana o ka ozone, ka pale ʻana i ka wā, ka pale ʻana i ka oxidation, ke kūpaʻa aila mineral, ke kūpaʻa aila, ka ʻaila hydraulic kūʻē, ke kūpaʻa ʻala a me nā mea hoʻoheheʻe he nui i ʻike ʻia no kāna mau mea kemika.
Ua kaupalena ʻia ka mahana hana ma lalo o ke sila static ma waena o -26°C a me 282°C. ʻOiai hiki ke hoʻohana ʻia i ka manawa pōkole ma kahi mahana o 295 ° C, e pōkole kona ola lawelawe ke ʻoi aku ka mahana ma mua o 282 ° C. ʻO ka mahana kūpono loa no ka hoʻohana ʻana ma lalo o ke sila ikaika ma waena o -15 ℃ a me 280 ℃, a hiki i ka wela haʻahaʻa ke hiki i -40 ℃.
ʻO ke apo hoʻopaʻa hoʻopaʻa Fluorine
(1) Piha i ka maʻalahi a me ke kūpaʻa;
(2) ʻO ka ikaika mechanical kūpono, me ka ikaika hoʻonui, ka lōʻihi a me ka pale ʻana i ka waimaka.
(3) Paʻa ka hana, ʻaʻole maʻalahi ka pehu i ka waena, a liʻiliʻi ka hopena hoʻoneʻe wela (Joule effect).
(4) He maʻalahi ka hana a me ke ʻano, a hiki ke mālama i nā ana kikoʻī.
(5) ʻAʻole ia e hōʻino i ka ʻili pili, ʻaʻole e hoʻohaumia i ka waena, etc.
ʻO nā pōmaikaʻi o ka apo fluorine rubber sealing
1. Pono ke apo sealing e hoʻokō maikaʻi i ka hana hoʻopaʻa ʻana i loko o ke kaomi hana a me kekahi ʻano wela, a hiki ke hoʻomaikaʻi ʻokoʻa i ka hana sealing e like me ka piʻi ʻana o ke kaomi.
2. He mea li'ili'i ke ku'eku'e ma waena o ke apo ho'opa'a sila a me ka ne'e 'ana, a pa'a ke ku'eku'e.
3. ʻO ke apo hoʻopaʻa hoʻopaʻa ʻana he ikaika ka corrosion kū'ē, ʻaʻole maʻalahi i ka makahiki, lōʻihi ke ola hana, maikaʻi ke pale ʻana i ka lole, a hiki ke hoʻopaʻi ʻokoʻa i kekahi ʻano ma hope o ka ʻaʻahu.
4. He hana maʻalahi, maʻalahi e hoʻohana a mālama i ke apo sealing, he aha nā mea maikaʻi o ka fluorine rubber sealing apo e hoʻolōʻihi i ke apo sealing.
Hoʻoholo ka hoʻolālā O-ring i ka hoʻohana ʻana i ka huahana
He kūpono ke apo sealing O-like no ka hoʻokomo ʻana ma luna o nā mea hana mechanical like ʻole, a ke pāʻani nei i kahi hana sila i loko o kahi kūlana kūʻokoʻa a neʻe paha i loko o kahi mahana kikoʻī, kaomi, a me nā media wai a me ke kinoea like ʻole.
