Loaʻa i ka hoʻonui ʻia ʻana o ka lāʻau lapaʻau maʻamau a me nā ʻano hana

ʻO nā mea nui oami hoʻonui lāʻauʻo ia nā: silica gel, nitrile rubber, neoprene,EPDM lāʻau, ka pulupulu maoli, ka pulupulu fluoro a me na laau e ae.

Hōʻike ʻia nā waiwai kino e ka pale ʻana i ka ʻaila, ka waikawa, ka alkali, ka abrasion, ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa.
1. Lapa maoli:

He kiʻekiʻe ka elasticity o nā hui synthetic, ka ikaika elongation kiʻekiʻe, ke kūpaʻa maikaʻi a me ka pale maloʻo, a hiki ke hoʻohana ʻia i nā mahana mai -60 ℃ a + 80 ℃. Hiki ke ʻano ka wai a me ke kinoea.
2. Pāpaʻa Butyl:

hoʻohana ʻia nā ʻaʻahu ʻaʻahu pale i nā paipu lepo a me nā ʻōnaehana one. ʻO ka ʻaʻahu a me ka corrosion-resistant rubber joint he ʻoihana ʻoihana hui i hoʻolālā kūikawā ʻia no nā ʻōnaehana desulfurization. Loaʻa iā ia ke kūpaʻa ʻaʻahu maikaʻi, ka waikawa a me ke kūpaʻa alkali, ka pale ʻana i ka corrosion, a hiki ke uku maikaʻi ʻia no ka hoʻonui axial, hoʻonui radial, angular displacement a me nā hana ʻē aʻe o nā pipeline desulfurization.
3. ʻAla Kloroprene (CR):

ʻO ka hui ʻana i ka wai kai kū i ke kai, nona ka oxygen maikaʻi a me ke kūʻē ozone, no laila ʻoi aku ka maikaʻi o kona kūpaʻa ʻelemakule. ʻO ka pae wela o ka hana: ma kahi o -45 ℃ a + 100 ℃, me ka wai kai ke kumu nui.
4. ʻAi Nitrile (NBR):

ʻAiʻa kūpaʻa ʻaʻa hui. ʻO ka hiʻohiʻona he kūpaʻa maikaʻi i ka ʻaila. Ka wela wela o ka hana: ma kahi o -30 ℃ a i+100 ℃. ʻO ka huahana e pili ana: ʻo ka hui pū ʻana i ka ʻaila kūʻokoʻa, me ka wai hoʻoheheʻe ma ke ʻano.
5. Ethylene propylene diene monomer (EPDM):

Hoʻohana maʻamau ʻia nā hui ʻana o ka ʻakika a me ka alkali, i hōʻike ʻia e ka ʻakika a me ke kūpaʻa alkali, me ka pae wela ma kahi o -30 ℃ a + 150 ℃. ʻO ka huahana kūpono: ʻākaika a me ka alkali kūʻokoʻa hui ʻana, ʻo ka ʻupena ka wai.

ʻO ka pulupulu Fluorine (FPM) he ʻōnaehana hana mahiʻai elastomer i hoʻokumu ʻia e ka copolymerization o ka fluorine me nā monomers. ʻO kona hiʻohiʻona he pale wela kiʻekiʻe a hiki i 300 ℃.

Hoʻokaʻawale a me nā hiʻohiʻona hana

Ma ke ʻano o ka hoʻohana ʻana, aia ʻekolu ʻano o ka lāʻau EPDM (ke koi nui ʻia no ka pale ʻana i ka wai, ke kū ʻana o ka mahu wai, a me ka pale ʻana i ka wā kahiko), ka ʻōpala maoli (hoʻohana nui ʻia no ka lāʻau e koi wale i ka elasticity), butyl rubber (ka ʻōpala e koi ai i ka hana sila maikaʻi. ), ka pulupulu nitrile (ka ʻōpala e pono ai ke kū i ka aila), a me ke silikoni (ka ʻōpala meaʻai);
Hoʻohana nui ʻia ka lāʻau sealing i nā ʻoihana e like me antistatic, flame retardant, electronics, chemical, pharmaceutical, a me ka meaʻai.

Hoʻokaʻawale ʻia nā mea hana o nā ʻāpana ʻāpana i nā ʻano like ʻole e pili ana i ke ʻano i hoʻohana ʻia, e like me ka chloroprene rubber, butyl rubber, fluororubber, EPDM rubber, a me ka rubber natural. Hoʻohana nui ʻia nā hui ʻana i nā paipu like ʻole, me nā hiʻohiʻona hana o ka haʻalulu haʻalulu, hoʻohaʻahaʻa leo, a me ka uku hoʻoneʻe.

ʻOkoʻa ka hana o nā hui ʻōpala ma muli o ka mea i hoʻohana ʻia. Hoʻokomo pū ka ʻokoʻa hana i ka fluororubber kūikawā a me ka rubber silicone, nona ke kūpaʻa ʻaʻahu, ka pale ʻana i ke kaomi, a me ke kūpaʻa wela kiʻekiʻe. Loaʻa iā ia ka pale ʻaila, ka waikawa a me ka alkali, ke anuanu a me ka wela, ka pale ʻana i ka wā kahiko, a me nā mea ʻē aʻe.
