Mea kipihe ʻano mea hoʻopaʻa paʻa hou, a he ʻano koʻikoʻi hoʻi ia o nā mea hoʻopaʻa paʻa i ka ʻoihana ʻoihana.Loaʻa iā ia ke kūpaʻa corrosion maikaʻi loa, ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, ka pale uila electromagnetic, ka mea liʻiliʻi friction, ka lubrication ponoʻī, ka elasticity, a me ka haʻahaʻa haʻahaʻa i nā wai a me nā kinoea.
Nā pahu graphitehiki ke hoʻopaʻa ʻia a hoʻopaʻa ʻia mai nā papa graphite maʻemaʻe a i ʻole metala (nā papa niho, nā papa pālahalaha, nā ʻupena) e hoʻoikaika hou i nā papa graphite e like me nā kūlana hana like.
1. Nā hiʻohiʻona o ka graphite gasket hikiwawe:
1. ʻO ka graphite maʻemaʻe kiʻekiʻe he maikaʻi ka impermeability i ke kinoea a me ka wai, e like me kahi pā lahilahi me ka mānoanoa o 0.125mm,ʻo ka helu o ka helium wale nō 2 * 10-1cm3 / s.
2. Kūleʻa wela maikaʻi.ʻO ka mahana o ka graphite maʻalahi ma ka non-hydrolytic medium he -200 ~ 600℃, akā he maʻalahi ke hoʻoheheʻe ʻia i loko o ka mea hydrolytic.
3. Anisotropy: ʻO ka conduction thermal, conductivity uila a me ka helu hoʻonui o ka graphite flexible i maopopo anisotropy.
4. Paʻa ikaika UV.
5. ʻO ke kūpaʻa kino maikaʻi, ke kūpaʻa kemika maikaʻi i nā mea hoʻoheheʻe kemika maʻamau, nā esters, ka mahu wai, ka hoʻohaʻahaʻa i ka media, etc.
Eia nō naʻe, aia kekahi mau palena i ka medium hydrolysis.
6. Haʻahaʻa haʻahaʻa, ikaika kiʻekiʻe, palupalu maikaʻi a me ke kūpaʻa.
Ka laulā o ka hoʻohana ʻana i ka graphite maʻalahi
Hoʻohana ʻia i nā flanges paipu ʻoihana, nā mea hoʻololi wela, nā uhi valve, condensers, ea amplifiers, exhaust pipes, refrigerators, etc.
Mea kūpono: ka wai, ka mahu, ka aila, ka waikawa, ka alkali, ka mea hoʻoheheʻe organik, ka amonia, ka hydrogen, etc.
2. Hoʻoikaika hou ke kila kila i ka graphite gasket
graphite kiʻekiʻe-ikaika gaskets, i ʻike ʻia ʻo graphite inorganic gaskets, i hana ʻia mai nā ʻāpana pepa graphite i hoʻoikaika ʻia a i ʻole ka lepo.Hiki ke hoʻopaʻa ʻia ka mea hoʻopaʻa ʻia e like me ka mea e pono ai.Ma muli o ka ikaika mechanical kiʻekiʻe o flexible graphite gaskets, ua kūpono ia no nā gaskets me nā diameters liʻiliʻi, a me ka hoʻoikaika hou ʻana i nā gaskets graphite e hoʻomaikaʻi nui i ka ikaika mechanical.ʻO nā waiwai maikaʻi loa e like me ke kūpaʻa kino kino, ka pale uila electromagnetic, ke kūpaʻa kiʻekiʻe / haʻahaʻa haʻahaʻa, a me ke ola lōʻihi.
Nā hoʻonui hou aku i ka hoʻokaʻawale ʻana i ka graphite gasket:
1. Hooikaika hou ke kila kalapona i kagraphite gasket: ʻO ka hope o ka pepa graphite maʻalahi e hoʻopaʻa ʻia me kahi kaula hao kalapona (0.2mm), a laila hoʻopaʻa ʻia, e hoʻoikaika ai i ka ikaika mechanical.
2. 304 kila kuhiliʻole hoʻoikaika 'ana i ka graphite gasket: flexible graphite flakes ua pili i na aoao elua o 304 kuhiliʻole kila, i loaʻa kiʻekiʻe loa mechanical ikaika.He kūpono no nā ʻano nui like ʻole a me nā ʻano paʻakikī, a maʻalahi hoʻi ke lawe.He kahua noi kaulana loa ia.He laulā o nā gaskets.
3. 316 kuhiliʻole kila hou hooikaika i ka graphite gasket: he maikai corrosion kū'ē a me kiʻekiʻe wela ikaika, akā, ke kumu kūʻai no hoi haʻahaʻa ma mua o nā mea'ē aʻe.
3. ʻO ka graphite metala i ulana ʻia i loko o ka gasket
ʻO nā kīʻaha metala-graphite i ulana ʻia he ʻano o nā pahu metala-inorganic i ulana ʻia mai nā ʻāpana metala a me nā ʻāpana graphite.Hoʻopili ʻia lākou mai nā ʻāpana kila lahilahi a me nā mea hoʻopihapiha.Me ka hoʻopaʻa ʻana i nā ʻāpana he nui a me nā hana hoʻopaʻa ponoʻī, ʻaʻole ia e palupalu i nā hemahema o ka flange i kaomi ʻia i loko o ka ʻili hoʻopaʻa, ʻaʻole ia ʻo NaCl flange sealing surface;he maʻalahi ka weheʻana, a hiki ke hoʻopau i ka hopena o ke kaomi, ka hoʻololi wela a me ka haʻalulu mechanical;hiki ke hoʻohana ʻia ma ke kiʻekiʻe wela a me ka haʻahaʻa haʻahaʻa E mālama ana i ka hana sealing maikaʻi loa ma lalo o nā kūlana koʻikoʻi like ʻole i nā hui kaʻa e like me , ʻūhā kiʻekiʻe, haʻalulu a haʻalulu.ʻO ka metala graphite i ulana ʻia gasket kūpono no ka mahana, a me ka maʻalahigraphitekūpono ke kāʻei no ka mahana -196~650°C (ʻaʻole emi ma lalo o 450°C i loko o ke kikowaena hydrolysis)
