He aha ka ʻokoʻa ma waena o Silicon Carbide a me Tungsten Carbide Mechanical Seals

ʻO nā ʻokoʻa nui ma waena o Silicon Carbide a me Tungsten Carbide Mechanical Seals

Hoʻohālikelike o nā ʻano kino a me nā mea kemika

ʻO Silicon Carbide, paʻa kēia pūhui i kahi ʻano crystalline i haku ʻia me nā ʻātoma kalapona a me ke kalapona.Hoʻopaʻa ia i ka conductivity thermal like ʻole ma waena o nā mea maka sila, ka paʻakikī kiʻekiʻe i helu ʻia ma 9.5 ma ka pālākiō Mohs - ʻelua wale nō i ke daimana - me ka waiwai kūʻē corrosion maikaʻi loa.ʻO ka SiC kekahi mea ʻeleʻa ʻole ka mea e hopena ai i ka paʻakikī kiʻekiʻe ma muli o kāna mau paʻa covalent hilinaʻi i ulu ʻia ma ke ʻano o ka mea.

ʻO Tungsten Carbide kahi huila i haku ʻia me nā mea Tungsten a me Carbon.Hoʻokumu ʻia ia ma o ke kaʻina hana i kapa ʻia ʻo sintering e loaʻa ai kahi helu waiwai paʻakikī loa ma waena o 8.5-9 ma ka pālākiō Mohs - paʻakikī no nā noi āpau i hoʻolei ʻia iā ia akā ʻaʻole paʻakikī e like me SiC.Ma waho aʻe o ka paʻakikī, hōʻike ka WC i kahi degere kupaianaha o ka rigidity a puni ka wela;akā naʻe, ʻoi aku ka paʻa o 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 ka silicon carbide (SiC) a me ka tungsten carbide (WC) mechanical seal ma lalo o nā ʻano hana like ʻole, pono ia e kūkākūkā i kā lākou pane ʻana i nā mea e like me ke kiʻekiʻe o ka wela, nā ʻano ʻokoʻa, nā media corrosive, a me ko lākou hiki ke mālama 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 maikaʻi i nā mahana kiʻekiʻe e hoʻohālikelike ʻia me ka tungsten carbide.Hana kēia hiʻohiʻona iā SiC i kahi koho kūpono no nā noi kahi mea koʻikoʻi ka hoʻomanawanui kiʻekiʻe.

Ma kahi ʻē aʻe, i ka wā e noʻonoʻo ai i ka pale ʻana i ke kaomi, paʻa ka tungsten carbide i kahi kūlana kūʻokoʻa ma mua o ka carbide silika.ʻO kona ʻano ʻoi aku ka ʻoi aku ka maikaʻi o ka pale ʻana i nā kūlana koʻikoʻi ma mua o SiC.No laila, ʻoi aku ka maikaʻi o nā sila WC no nā noi kaumaha me nā koʻikoʻi kiʻekiʻe.

Ma muli o ka media hana i hōʻike ʻia ai kēia mau sila, lilo ke kūpaʻa corrosive i mea nui ʻē aʻe no ka loiloi.ʻOi aku ka maikaʻi o ka carbide silikoni i ka tungsten carbide i ke kūʻē ʻana i nā hopena acidic a me ka alkaline ma muli o kona ʻano kūlohelohe.No laila, ʻoi aku ka maikaʻi o nā sila SiC i nā ʻoihana e pili ana i nā wai a me nā kinoea.

ʻO ke kūpaʻa ʻana ma waena o kēia mau ʻano sila ʻelua e hoʻololi hou i ka tungsten carbide ma muli o kona ʻano paʻakikī, ʻoi aku ka mākaukau no ka mālama ʻana i nā kūlana abrasive i nā manawa hoʻohana lōʻihi.

Hoʻohālikelike Kūʻai
ʻO ka maʻamau, ʻoi aku ke kiʻekiʻe o ke kumu kūʻai mua o nā sila tungsten carbide ma mua o nā mea like silicon carbide ma muli o kona ʻoi aku ka maikaʻi o ka ʻaʻahu a me ka paʻakikī.Eia nō naʻe, he mea koʻikoʻi ka noʻonoʻo ʻana ʻaʻole wale i nā kumukūʻai mua, akā i nā koina hana lōʻihi.

ʻOiai e koi ana nā sila tungsten carbide i kahi hoʻopukapuka mua ʻoi aku ka nui, hiki i ko lākou lōʻihi a me ka maikaʻi ke hoʻopau i kēia kumukūʻai mua i ka manawa.Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka liʻiliʻi o nā sila silicon carbide i mua e hoʻolilo iā lākou i koho maikaʻi no nā ʻoihana ʻike kālā.Eia nō naʻe, ma muli o ka haʻahaʻa haʻahaʻa o ko lākou pale ʻana i ka lole i kekahi mau kūlana, pono paha lākou e hoʻololi pinepine a mālama paha e alakaʻi i nā kumukūʻai lōʻihi.

Nā ʻokoʻa i ka lōʻihi a me ka pale ʻana i ka lole
Loaʻa i nā sila mechanical Silicon Carbide ka paʻakikī i hui pū ʻia me ka conductivity thermal kiʻekiʻe.ʻO kēia hui pū ʻana e liʻiliʻi loa lākou i ka ʻaʻahu ma muli o ka friction, e hōʻemi ana i ko lākou manawa o ka deformation ʻoiai ma lalo o nā kūlana hana koʻikoʻi.Eia kekahi, ʻo kā lākou pale ʻana i ka corrosion kemika e hoʻonui i ko lākou lōʻihi holoʻokoʻa.

Ma ka ʻaoʻao ʻē aʻe, hāʻawi ʻo Tungsten Carbide mechanical seal i ka ikaika like ʻole a me ka rigidity, e kōkua maikaʻi iā lākou e kū i ke koʻikoʻi kino no nā manawa lōʻihi.ʻO kā lākou paʻa paʻa e hōʻoia i ka hana maʻamau ʻoiai ke kau ʻia i nā kūlana koʻikoʻi, e hoʻokiʻekiʻe nui i ko lākou pale ʻana.

Paʻa maoli nā mea ʻelua i ka hoʻonui wela;akā naʻe, hōʻike ʻo Silicon Carbide i kahi ʻoi aku ka maikaʻi o ka haʻalulu wela i hoʻohālikelike ʻia me Tungsten Carbide.ʻO ke ʻano kēia, ʻaʻole liʻiliʻi paha nā sila SiC i ka haki ʻana a i ʻole ke ʻano ʻino ke ʻike ʻia i ka hoʻololi wikiwiki ʻana o ka mahana - kahi mea e hāʻawi maikaʻi i ke ʻano o ka lōʻihi.

Pehea e koho ai ma waena o Silicon Carbide a me Tungsten Carbide Mechanical Seals
ʻO ka mea nui, pono e noʻonoʻo i ke kaiapuni kahi e hana ai nā sila.E noʻonoʻo i nā mea e like me ke ʻano o ke kaʻina hana, nā pae wela, nā pae paʻi, a me ka hiki o nā mea corrosive.Manaʻo nui ʻia ʻo WC no kona ʻano paʻa a me ke kūpaʻa ʻana i ka ʻaʻahu.No laila, hiki ke makemake ʻia i loko o nā kaiapuni e koi ana i ka paʻa i ka abrasion a i ʻole nā ​​​​koi ikaika.

Ma ka ʻaoʻao ʻē aʻe, hōʻike ʻo SiC i ke kūpaʻa maikaʻi loa i ka haʻalulu wela a me ka corrosion i mea kūpono no nā noi kahi e manaʻo ʻia ai nā loli nui o ka mahana a i ʻole nā ​​​​wai wai corrosive.ʻO kāna mau hiʻohiʻona haʻahaʻa haʻahaʻa haʻahaʻa e hōʻike ana i ka hoʻohana ʻana i ka ikehu liʻiliʻi no laila e hana ai i nā sila SiC kūpono no nā hana pili i ka ikehu.

Eia kekahi, ʻaʻole pono e mālama ʻia nā noʻonoʻo kālā i ka wā e koho ai;ʻoiai ʻo WC e kaena nei i ka paʻakikī a me ka hoʻohana ʻana i nā waiwai kūʻē, ʻoi aku ka maikaʻi ma mua o nā hoa SiC.No laila, inā he kumu palena ʻole ka hoʻopaʻa kālā, ʻo ke koho ʻana iā SiC he hopena hiki ke kūpono inā ʻaʻohe kūlana hana koʻikoʻi.

ʻO ka mea nui loa, ʻo kāu kūpaʻa inoa a i ʻole ka ʻike mua me nā sila mīkini carbide silicon a i ʻole nā ​​sila tungsten carbide mechanical.Ke hoʻomau nei kekahi mau ʻoihana i ka hoʻohana ʻana ma muli o ka ʻikepili mōʻaukala a i ʻole nā ​​​​ʻike hana i hala ma mua o ka hoʻohana ʻana i kekahi ʻano ma luna o kekahi ʻano kūpono mai kahi hiʻohiʻona hilinaʻi.

I ka hopena
I ka hopena, ʻo Silicon Carbide a me Tungsten Carbide mechanical seal he ʻelua ʻano hopena ʻokoʻa no ka lawelawe ʻana i nā noi mechanical.ʻOiai ke hāʻawi nei ʻo Silicon Carbide i ke kūpaʻa wela a me ke kūpaʻa kemika, kaulana ʻo Tungsten Carbide no kona kūpaʻa a me ka ikaika ma lalo o nā kūlana koʻikoʻi.ʻO kāu koho ma waena o kēia mau mea ʻelua e alakaʻi ʻia e kāu mau pono kikoʻī a me nā koi noi;ʻaʻohe mea hoʻonā honua.ʻO kā mākou hui loea ma XYZ Inc. ʻoi aku ka maikaʻi i ka hāʻawi ʻana i nā hoʻonā kūpono e hoʻokūkū i nā pono ʻoihana like ʻole me ka maikaʻi.

I kēia manawa ua ʻike ʻoe i nā ʻokoʻa ma waena o Silicon Carbide a me Tungsten Carbide mechanical seal, akā maopopo, hiki ke paʻakikī ka hoʻomaopopo ʻana i ka mea e pili pono ana me kāu mau mea hana a me nā hana.Makemake ʻo Fortune i ka ʻike!No laila e hōʻoia ʻoe e hoʻolako iā ʻoe iho me nā ʻōlelo aʻoaʻo hoʻolālā i kūpono i kāu kikoʻī ʻoihana.
