ʻO ka lāʻau fluorine kahi ʻano ʻōpala synthetic i loaʻa nā ʻātoma fluorine. Loaʻa iā ia ke kūpaʻa wela maikaʻi loa, ka pale ʻana i ka oxidation, ka pale ʻana i ka ʻaila a me ka lāʻau kūʻē. Hoʻohana nui ʻia ia i ka mokulele, ʻoihana kemika, ʻaila, kaʻa a me nā keʻena ʻoihana ʻē aʻe e like me ka mea sealing material, medium resistant material and insulating material. He lāʻau synthetic i loaʻa nā ʻātoma fluorine i loko o kona ʻano molekala.
Hōʻike maʻamau ia e ka helu o nā ʻātoma fluorine o nā ʻāpana fluorine i loko o ka copolymer. No ka laʻana, ʻo ka fluororubber 23 he copolymer o ka vinylidene fluoride a me ka chlorotrifluoroethylene. Kūleʻa ka Fluororubber i ka wela kiʻekiʻe, ka ʻaila a me ka ʻino kino.
ʻO nā pono o ka fluororubber:
1. Kūleʻa wela kiʻekiʻe maikaʻi loa: ʻo ke ana wela o ka lawelawe mai - 60 ℃ a 250 ℃. ʻOi aku ka maikaʻi o ka pale ʻana i ka aila: ʻoi aku ka maikaʻi o ke kūʻē ʻana i ka aila wahie wela kiʻekiʻe, ka aila lubricating sulfur, ka aila hydraulic, ka aila diester, ka silicate ester a me nā aila ʻē aʻe ma mua o nā rubbers ʻē aʻe.
3. Ke kū'ē maikaʻi loa i ke kino corrosive ikaika a me ka oxidant ikaika; ʻOi aku ka maikaʻi o kona kūpaʻa ʻana i nā media corrosive ikaika e like me ka fuming nitric acid, concentrated sulfuric acid, hydrochloric acid, hydrogen peroxide a me ka alkali concentrated ma mua o nā rubbers ʻē aʻe.
4. ʻO nā waiwai mechanical maikaʻi, ka hoʻopili uila a me ke kū'ēʻana i ka radiation.
5. Ke kū'ē maikaʻi i ka vacuum kiʻekiʻe.
Ka laulā noi o ka fluororubber:
1. Ke hoʻopiliʻia ka'ōpala fluorine e ka maʻamau a me ka wai aiʻole i ka piʻiʻana o ka mahana, ua liʻiliʻi ka loli. ʻOiai inā he insulator ka silicon dioxide i hana ʻia e ka hoʻopau pōkole pōkole, e hōʻoiaʻiʻo ia e hoʻomau ka hana o nā mea uila, no laila kūpono ia no ka hana ʻana i nā uwea, nā uwea a me nā uea alakaʻi.
2. Hiki ke hoʻohana ʻia ka paipu Fluoroplastic no ka lawe ʻana a hoʻopaʻa ʻana i nā ʻakika ikaika like ʻole a me ka alkali, ka mahu, ka ea wela, ka aila wela a me nā wai ʻē aʻe. Hiki ke hoʻohanaʻia no nā mea hana hale, nā kukui a me nā mea lapaʻau; 3. Hiki ke pale ʻia ke kaomi hana o ka paipu fluororubber (0.5-3.0 MPa) e ka uhi ʻupena hui a me ke kila kila.
4. Hoʻohana pū ʻia ke kāʻei Fluoroplastic no ka ʻaʻahu uea i ka hana ʻino.;
5. Loaʻa i ka Fluororubber ke kūlana kiʻekiʻe kiʻekiʻe a me ka pale ʻana i ka corrosion, a ʻo ia ka inoa o ke aliʻi o ka lāʻau. Hiki ke hana ʻia i loko o ka ipu hao, lipine adhesive, film, gasket, (framework) oil seal, "O" ring, "V" ring, etc., i hoʻohana nui ʻia i ka mokulele, kaʻa, petroleum, ʻoihana kemika, kelepona, mea kani a me nā kula ʻē aʻe.
E like me kā mākou i ʻike ai, pono e hoʻohana kēlā me kēia valve i nā mea hoʻopaʻa hoʻopaʻa ʻokoʻa, e like me ka ethylene propylene rubber (EPDM), nitrile rubber (NBR), polytetrafluoroethylene (PTFE), fluororubber (Viton), silicone rubber (SEP), ka wela a me ka hoʻohana ʻana i ka lāʻau pale EPDM, ka carbide cemented, ke kila kila.
