He aha nā mea i kūpaʻa loa i ka abrasion?

He aha ka mea kūpaʻa loa? I ka wā e pili ana i nā mea e hiki ke kū i ka ʻaʻahu a me ka haehae, aia kekahi mau koho e noʻonoʻo ai. ʻElua mau mea maʻamau i hoʻohana ʻia no nā noi kū i ka abrasion he alumina ceramics a me silicon carbide ceramics.

 ʻO nā keramika alumina, i ʻike ʻia hoʻi he alumini oxide, he ʻano keramika ia e kūpaʻa loa i ka ʻaʻahu a me ka haehae. Hana ʻia kēia mea me ka alumini oxide, nona nā pae kiʻekiʻe o ka paʻakikī a me ka paʻakikī. Hoʻohana pinepine ʻia nā keramika alumina ma ke ʻano he mau mea kūpaʻa i ka abrasion ma nā ʻano ʻoihana like ʻole, me ka hana ʻeli ʻana, ka sima, a me ka hana mana.

 ʻO kekahi ʻano keramika i hoʻohana pinepine ʻia no nā noi kū i ka abrasion ʻo ia nā keramika silicon carbide. ʻO Silicon carbide kahi mea i haku ʻia me ka silicon a me ke kalapona, a ua ʻike ʻia no kona paʻakikī a me ke kūpaʻa i ka ʻaʻahu a me ka haehae. Hoʻohana ʻia nā keramika Silicon carbide i nā ʻoihana e like me ke kaʻa a me ka aerospace, a me ka hana ʻana i nā mea ʻoki a me nā mea abrasive.

 I ke koho ʻana ma waena o nā keramika alumina a me nā keramika silicon carbide no nā noi kū i ka abrasion, he mea nui e noʻonoʻo i nā koi kikoʻī o ka noi. ʻOiai ʻo nā mea ʻelua he kūpaʻa loa i ka ʻaʻahu a me ka haehae, he ʻokoʻa ko lākou mau waiwai e hiki ai ke kūpono i kekahi no kahi noi kikoʻī ma mua o kekahi.

 Eia kekahi laʻana, ʻike ʻia nā keramika alumina no ko lākou kūpaʻa kemika kiʻekiʻe a me ke kūpaʻa wela. ʻO kēia ka mea kūpono iā lākou no ka hoʻohana ʻana i nā noi kahi e hopohopo ai ka ʻike ʻana i nā kemika ʻino a i ʻole nā ​​​​mahana kiʻekiʻe. Ma ka ʻaoʻao ʻē aʻe, ʻike ʻia nā keramika silicon carbide no ko lākou ikaika kiʻekiʻe a me ka paʻakikī, kahi e kūpono ai lākou no nā noi kahi e pono ai nā pae kiʻekiʻe o ke kūpaʻa abrasion.

 ʻO kahi hoʻohana ʻana i nā mea pale i ka ʻānai ʻia ʻo ia ka uhi o nā chutes. Hoʻohana ʻia nā chutes e lawe i nā mea mai kekahi wahi a i kekahi wahi, a pinepine lākou i ke komo ʻana a me ka haehae ʻana ma muli o ke ʻano abrasive o nā mea e lawe ʻia ana. I mea e pale ai i ka hōʻino ʻana i ka chute a hōʻoia i kahi ola lawelawe lōʻihi, he mea nui e hoʻohana i kahi mea e hiki ke kū i ka abrasion.

 Nā Pālolo ChemshunNā liner chute seramikahe koho maikaʻi loa no nā noi kahi e pono ai ke kū'ē i ka abrasion. Hoʻohana pinepine ʻia nā keramika alumina a me nā keramika silicon carbide no nā liner chute ma muli o ko lākou kiʻekiʻe o ke kū'ē ʻana i ka abrasion. Ma waho aʻe o ko lākou kū'ē ʻana i ka ʻaʻahu a me ka haehae, ua ʻike ʻia nā liner chute ceramic no ko lākou hiki ke hōʻemi i ka walaʻau a me ka haʻalulu, hiki ke lilo i mea pono i kekahi mau noi.

 I ka hopena, i ka wā e pili ana i nā mea pale i ka abrasion, ʻo nā keramika alumina a me nā keramika silicon carbide ʻelua o nā koho maʻamau. He kūpaʻa loa nā mea ʻelua i ka ʻaʻahu a me ka haehae, akā he mau waiwai like ʻole e hiki ai i kekahi ke kūpono no kahi noi kikoʻī ma mua o kekahi. He noi maikaʻi loa nā liner chute keramika no nā ʻano keramika ʻelua, no ka mea hiki iā lākou ke kū i ke ʻano abrasive o nā mea e lawe ʻia ana me ka hoʻēmi ʻana i ka walaʻau a me ka haʻalulu.
