Nā ʻokoʻa koʻikoʻi ma waena o Silicon Carbide a me Tungsten Carbide Mechanical Seals
Hoʻohālikelike o nā Waiwai Kino a me nā Waiwai Kemika
ʻO Silicon Carbide, paʻa kēia hui i kahi ʻano crystalline i haku ʻia me nā ʻātoma silicon a me ke kalapona. Paʻa ia i ka conductivity thermal i hoʻokūkū ʻole ʻia ma waena o nā mea sila, paʻakikī kiʻekiʻe i helu ʻia ma 9.5 ma ka unahi Mohs - ʻo ka lua wale nō i ka daimana - me ka waiwai kūpaʻa maikaʻi loa. ʻO SiC kekahi mea keramika non-oxide e hopena i ka paʻakikī kiʻekiʻe ma muli o kona mau pilina covalent hilinaʻi i ulu pololei ma o ka mea.
He mea hoʻohuihui ʻo Tungsten Carbide i haku ʻia me nā mea Tungsten a me Carbon. Hana ʻia ia ma o kahi kaʻina hana i kapa ʻia ʻo sintering e hopena i kahi helu mea paʻakikī loa ma waena o 8.5-9 ma ka unahi Mohs - ua lawa ka paʻakikī no kekahi noi i hoʻolei ʻia iā ia akā ʻaʻole paʻakikī e like me SiC. Ma waho aʻe o ka paʻa, hōʻike ʻo WC i kahi kekelē kupaianaha o ka paʻakikī a puni ka wela; akā naʻe, ʻaʻole ia i paʻa i ka kemika i hoʻohālikelike ʻia me Silicon Carbide.
Nā ʻokoʻa o ka hana ma lalo o nā kūlana hana like ʻole
I ka hoʻohālikelike ʻana i ka hana o nā sila mechanical silicon carbide (SiC) a me tungsten carbide (WC) ma lalo o nā ʻano hana like ʻole, he mea nui e kūkākūkā i kā lākou pane ʻana i nā mea e like me ke kiʻekiʻe o ka mahana, nā ʻano loli o ke kaomi, nā mea ʻino, a me ko lākou hiki ke lawelawe i nā kūlana abrasive.
Ma ke ʻano o ke kūpaʻa wela, hōʻike ka silicon carbide i ka conductivity thermal maikaʻi loa a hiki ke hana pono i nā mahana kiʻekiʻe e hoʻohālikelike ʻia me ka tungsten carbide. ʻO kēia ʻano e hoʻolilo iā SiC i koho kūpono no nā noi kahi e koʻikoʻi ai ke kūpaʻa wela kiʻekiʻe.
I ka ʻaoʻao ʻē aʻe, i ka noʻonoʻo ʻana i ke kū'ē ʻana i ke kaomi, loaʻa i ka tungsten carbide kahi pono kūikawā ma mua o ka silicon carbide. ʻO kona ʻano paʻa e hiki ai iā ia ke kū i nā kūlana kaomi koʻikoʻi ma mua o SiC. No laila, ʻoi aku ka kūpono o nā sila WC no nā noi hana kaumaha me nā kaomi kiʻekiʻe.
Ma muli o ka pāpāho hana i hōʻike ʻia ai kēia mau sila, lilo ke kūpaʻa corrosive i mea koʻikoʻi no ka loiloi. ʻOi aku ka maikaʻi o ka Silicon carbide ma mua o ka tungsten carbide i ke kūʻē ʻana i nā hopena acidic a me alkaline ma muli o kona ʻano inert kemika. No laila, makemake ʻia nā sila SiC i nā ʻoihana e hana ana me nā wai a i ʻole nā kinoea huhū.
Hoʻi hou ke kūpaʻa o ka ʻaʻahu ma waena o kēia mau ʻano sila ʻelua i ka manaʻo o ka tungsten carbide ma muli o kona paʻakikī kūlohelohe, e ʻoi aku ka mākaukau e lawelawe i nā kūlana abrasive ma luna o nā wā hoʻohana lōʻihi.
Hoʻohālikelike Kumukūʻai
ʻO ka maʻamau, ʻoi aku ke kiʻekiʻe o ke kumukūʻai mua o nā sila tungsten carbide ma mua o nā mea like silicon carbide ma muli o kona kūpaʻa ʻana i ke kapa komo a me nā waiwai paʻakikī. Eia nō naʻe, he mea nui e noʻonoʻo ʻaʻole wale i nā kumukūʻai mua, akā, i nā lilo hana lōʻihi hoʻi.
ʻOiai paha e koi ana nā sila tungsten carbide i kahi hoʻopukapuka mua nui aʻe, hiki i ko lākou lōʻihi a me ka pono ke hoʻopau i kēia lilo mua i ka hala ʻana o ka manawa. Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka liʻiliʻi o ke kumukūʻai o nā sila silicon carbide ma mua, kahi e lilo ai lākou i koho hoihoi no nā ʻoihana mālama kālā. Eia nō naʻe, no ko lākou kūpaʻa haʻahaʻa i ka ʻaʻahu ʻana i kekahi mau kūlana, pono paha lākou i nā hoʻololi pinepine a i ʻole ka mālama ʻana e alakaʻi ana i nā kumukūʻai lōʻihi.
Nā ʻokoʻa ma ke kūpaʻa a me ke kūpaʻa ʻana i ka lole
Loaʻa i nā sila mīkini Silicon Carbide ka paʻakikī kūikawā i hui pū ʻia me ka conductivity thermal kiʻekiʻe. ʻO kēia hui pū ʻana e hoʻemi iā lākou i ka maʻalahi o ke komo ʻana ma muli o ka friction, e hōʻemi ana i ko lākou manawa kūpono o ka deformation ʻoiai ma lalo o nā kūlana hana koʻikoʻi. Eia kekahi, ʻo ko lākou resistivity e kūʻē i ka corrosion kemika e hoʻonui hou i ko lākou kūpaʻa holoʻokoʻa.
Ma ka ʻaoʻao ʻē aʻe, hāʻawi nā sila mechanical Tungsten Carbide i ka ikaika a me ka paʻakikī i kūlike ʻole, kahi e kōkua pono ai iā lākou e kū i nā kaomi kino nui no nā wā lōʻihi. ʻO ko lākou kūpaʻa e hōʻoia i ka hana mau ʻoiai ke kau ʻia i nā kūlana paʻakikī, e hoʻokiʻekiʻe nui ana i ko lākou kūpaʻa ʻana i ka ʻaʻahu.
He kūpaʻa kūlohelohe nā mea ʻelua i ka hoʻonui wela; akā naʻe, hōʻike ʻo Silicon Carbide i ke kūpaʻa haʻalulu wela ʻoi aku ka maikaʻi ma mua o ka Tungsten Carbide. ʻO ke ʻano kēia, ʻaʻole hiki ke haki a hoʻololi paha nā sila SiC i ka wā e hōʻike ʻia ai nā loli wikiwiki o ka mahana—he mea e hāʻawi maikaʻi ana i ka lōʻihi.
Pehea e koho ai ma waena o nā sila mīkini Silicon Carbide a me Tungsten Carbide
ʻO ka mea nui, he mea nui e noʻonoʻo i ke kaiapuni kahi e hana ai nā sila. Hoʻomaopopo kēlā i nā mea e like me ke ʻano o ke kahe hana, nā pae mahana, nā pae kaomi, a me ka hiki ke loaʻa nā mea ʻino. Ua mahalo nui ʻia ʻo WC no kona paʻakikī a me ke kūpaʻa i ka ʻaʻahu ʻana. No laila, hiki ke makemake ʻia i nā wahi e koi ana i ka paʻa e kūʻē i ka abrasion a i ʻole nā paʻi koʻikoʻi.
Ma ka ʻaoʻao ʻē aʻe, hōʻike ʻo SiC i ke kūpaʻa maikaʻi loa i ka haʻalulu wela a me ka palaho e kūpono ai no nā noi kahi e manaʻo ʻia ai nā loli nui o ka mahana a i ʻole nā wai wai ʻino loa. ʻO kona mau ʻano haʻahaʻa haʻahaʻa haʻahaʻa e hōʻike ana i ka hoʻohana ʻana i ka ikehu liʻiliʻi e hana ana i nā sila SiC kūpono no nā hana koʻikoʻi i ka ikehu.
Eia kekahi, ʻaʻole pono e hoʻowahāwahā ʻia nā noʻonoʻo kālā i ka wā e koho ai i kēia; ʻoiai ʻo WC e haʻaheo nei i ka paʻakikī kiʻekiʻe a me nā waiwai kūpaʻa i ke komo ʻana, ʻoi aku ke kumukūʻai ma mua o nā hoa SiC. No laila, inā he kumu kaupalena nā palena kālā, ʻo ke koho ʻana iā SiC he hopena kūpono paha inā ʻaʻohe kūlana hana koʻikoʻi/hōʻino.
ʻO ka mea hope loa akā he mea nui, ʻo ia ka kūpaʻa o kāu brand a i ʻole ka ʻike mua me nā sila mechanical silicon carbide a i ʻole nā sila mechanical tungsten carbide. Ke hoʻomau nei kekahi mau ʻoihana i ka hoʻohana ʻana ma muli o ka ʻikepili mōʻaukala a i ʻole nā ʻike hana i hala o ka hoʻohana ʻana i hoʻokahi ʻano ma luna o kekahi e like me ke kūpono mai kahi hiʻohiʻona hilinaʻi.
I ka hopena
I ka hopena, ʻo nā sila mīkini ʻo Silicon Carbide a me Tungsten Carbide he ʻelua mau hopena like ʻole no ka lawelawe ʻana i nā noi mīkini. ʻOiai ʻo Silicon Carbide e hāʻawi ana i ke kūpaʻa wela kupaianaha a me ke kūpaʻa kemika, ua kaulana ʻo Tungsten Carbide no kona kūpaʻa a me ka ikaika ma lalo o nā kūlana koʻikoʻi. Pono e alakaʻi ʻia kāu koho ma waena o kēia mau mea ʻelua e kāu mau pono kikoʻī a me nā koi noi; ʻaʻohe hopena honua. ʻOi aku ka maikaʻi o kā mākou hui loea ma XYZ Inc. i ka hāʻawi ʻana i nā hopena adaptive e hoʻohālikelike i nā pono ʻoihana like ʻole me ka pono.
Ua ʻike ʻoe i nā ʻokoʻa ma waena o nā sila mechanical Silicon Carbide a me Tungsten Carbide, akā ʻoiaʻiʻo, ʻo ka hoʻomaopopo ʻana i ka mea e kūlike me kāu mau lako hana a me nā hana hiki ke paʻakikī. Makemake ka waiwai i ka poʻe ʻike! No laila e hōʻoia e hoʻolako iā ʻoe iho me nā ʻōlelo aʻoaʻo hoʻolālā i hana ʻia no kāu ʻoihana kikoʻī.
