Puka Viton Rubber

ʻO Fluororubber gasket kahi mea hoʻopaʻa i hana ʻia me nā polymers synthetic me nā ʻātoma fluorine ma nā ʻāpana kalapona o nā kaulahao nui a ʻaoʻao paha. ʻO kēia ʻano lāʻau lapaʻau, ma muli o kona ʻano molekala kū hoʻokahi, e hōʻike ana i nā pono kūikawā ʻaʻole hiki ke hoʻohālikelike ʻia ka lāʻau maʻamau. He nui kona mau waiwai maikaʻi a hoʻohana nui ʻia i nā ʻoihana ʻoihana lehulehu. Loaʻa i nā ʻeke fluororubber (fluororubber gaskets) nā hiʻohiʻona o ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa ʻaila, ka waikawa a me ke kūpaʻa alkali. ʻO -30 degere a hiki i ka +250 degere kona pae wela hana, a hiki i ka 3.0MPa ke kaomi hana. ʻOi aku kona ikaika tensile ma mua o 7.5MPa, ʻoi aku ka elongation ma mua o 100%, a ʻoi aku ka paʻakikī o Shore ma mua o 70.

He "akamai sealing" ma lalo o nā kūlana hana koʻikoʻi, me nā pōmaikaʻi koʻikoʻi e like me ke kūpaʻa ʻana i nā wela kiʻekiʻe a me nā haʻahaʻa haʻahaʻa, ʻino kemika a me ke ola lawelawe lōʻihi loa. Hoʻohana nui ʻia ia i nā kula me nā koi kiʻekiʻe loa no ka hilinaʻi hoʻopaʻa ʻana, e like me ka ʻenekinia kemika, ka ikehu a me ka mokulele. ʻOiai ke kumukūʻai kiʻekiʻe, ʻaʻole hiki ke hoʻololi ʻia kāna hana a he mea nui ia e hōʻoia i ka hana palekana o nā mea hana.

Nui ākea ākea o ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa
ʻO ka laulā wela hana maʻamau he -20 degere a 200 degere. Hiki ke haʻahaʻa haʻahaʻa e like me ka -40 degere a i ʻole ka kiʻekiʻe e like me 260 degere kekahi mau ʻano hoʻohālikelike i hoʻololi ʻia. Hiki iā ia ke pale i nā mahana ma luna o 300 degere no kahi manawa pōkole (he mau hola), ʻoi aku ma mua o ka palena hoʻomanawanui o nā rubbers maʻamau (e like me ka nitrile rubber a me ka chloroprene rubber), a kūpono no ka hoʻopaʻa ʻana i nā mea wela wela (e like me nā paipu hoʻopau engine a me nā flanges umu).

Kūleʻa kemika maikaʻi loa
He kūpaʻa ia i ka hapa nui o nā media kemika, me
ʻO nā mea ʻino ikaika: nā waikawa (e like me ka sulfuric acid, hydrochloric acid), nā kumu (e like me ka sodium hydroxide), nā mea hoʻoheheʻe kūlohelohe (e like me ka acetone, toluene);
ʻO nā ʻaila a pau: ka aila mineral, ka aila hydraulic, ka ʻaila, diesel, a me nā aila polar ikaika;
Nā kinoea ʻenehana: ozone, chlorine, fluorine a me nā kinoea corrosive ʻē aʻe.
ʻO kēia hiʻohiʻona ka mea i makemake nui ʻia no ka hoʻopaʻa ʻana i nā kaiapuni e like me ka ʻenekinia kemika a me nā lāʻau lapaʻau.

ʻO ke kūpaʻa ʻelemakule ikaika loa a me ka pale ʻana i ka wā
ʻAʻole maʻalahi ia i ka haki ʻana, ka paʻakikī a i ʻole ka hoʻohaʻahaʻa ʻana ke ʻike ʻia i nā kukuna ultraviolet, ka ozone, ka haʻahaʻa a i ʻole ka wela kiʻekiʻe no ka manawa lōʻihi. ʻOi aku ka lōʻihi o kona ola lawelawe ma mua o ka lāʻau lapaʻau maʻamau (maʻa mau 3 a 5 mau manawa o ka nitrile rubber), a ua kūpono ia no nā lako waho i hoʻohana ʻia no ka manawa lōʻihi a i ʻole e hana ana no ka manawa lōʻihi (e like me nā papa hana ʻaila a me nā pipelines nuclear power plant).

Kiʻekiʻe sealing paʻa
Loaʻa iā ia ka compressibility maikaʻi a me ka resilience a me ke kū'ē creep. Hiki iā ia ke mālama i ka hoʻopaʻa paʻa ʻia ma lalo o ka -mau haʻawe kaomi lōʻihi a ʻaʻole pili i ka hapa nui o nā mea e hoʻopaʻa ai (e like me ka metala, keramik, plastik, a me nā mea ʻē aʻe).
