ʻO ka hale hana hoʻoili ʻoihana 'wear-resistant powerhouse': ka ikaika paʻakikī o ka pamu slurry silicon carbide

I ke kaʻina hana lawe mea o nā ʻoihana e like me ke kālai ʻana, ka metallurgy, a me ka ʻenekinia kemika, ʻo nā pamu slurry he "mea hoʻoneʻe" maoli ke kuleana no ka lawe ʻana i nā media e like me ka slurry a me ka lepo e loaʻa ana nā ʻāpana paʻa. Eia nō naʻe, he pōkole ke ola o nā pamu slurry maʻamau a he palupalu i lalo o ke ʻano kiʻekiʻe o ka ʻaʻahu a me nā kūlana pala ikaika, ʻoiai ke kū mai nei onā pamu slurry silicon carbidehoʻoponopono pololei i kēia pilikia lōʻihi.
Inā ʻo ka ʻāpana overcurrent o ka pamu maʻamau he "kīʻaha laiki plastik" e haki ana ke kuʻi i kahi ʻili paʻakikī, a laila ʻo ka ʻāpana overcurrent i hana ʻia me ka mea silicon carbide he "kīʻaha daimana" me ka paʻakikī ʻelua ma hope o ke daimana. I ka lawe ʻana i nā mea hana i loaʻa ke one, ka ʻiliʻili, a me ka slag, holoi mau nā ʻāpana kahe wikiwiki i ke kino pamu, akā hiki i nā ʻāpana silicon carbide ke noho "neʻe ʻole", me ke kūpaʻa ʻana o ka ʻaʻahu e ʻoi aku ka nui ma mua o nā mea metala, e hoʻolōʻihi nui ana i ke ola lawelawe o ka pamu a hoʻemi i ka pilikia o ka hoʻōki a me ka hoʻololi ʻana i nā ʻāpana.

Ma waho aʻe o ke kūpaʻa ʻana i ke komo ʻana, hele pū mai ka pamu slurry silicon carbide me kahi "anti-corrosion buff". Loaʻa i ka nui o nā media ʻoihana nā waikawa ikaika a me nā alkalis, a e pala koke ʻia nā pamu metala maʻamau a piha i nā lua. Eia nō naʻe, he mau waiwai kemika paʻa ko ka silicon carbide, e like me ke kau ʻana i kahi papa o "anti-corrosion armor" ma ke kino pamu. Hiki iā ia ke lawelawe mālie i nā media corrosive like ʻole a ʻaʻole hopohopo hou e pili ana i nā ulia hana i hoʻokumu ʻia e nā leaka corrosion.
ʻO ka mea ʻoi aku ka noʻonoʻo, ʻo ia ka laumania o ka paia o loko o ka ʻāpana kahe o ka pamu slurry silicon carbide, e hopena ana i ka pale haʻahaʻa i ka lawe ʻana i nā mea. ʻAʻole wale kēia e hōʻemi i ka hoʻohana ʻana i ka ikehu, akā e hōʻemi pū i ka waiho ʻana a me ka pale ʻana o nā ʻāpana i loko o ka mea i loko o ka pamu. ʻOiai kona "kino paʻakikī", ʻaʻohe hopohopo a me ka pono e hoʻohana. I nā kūlana e pono ai ka lawe lōʻihi a me ka ikaika o nā mea paʻi paʻi paʻi, he "limahana akamai" hilinaʻi ia.
I kēia mau lā, ua lilo nā pamu slurry silicon carbide i mea hana makemake nui ʻia ma ke kahua lawe ʻoihana ma muli o ko lākou mau pono pālua o ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa ʻana i ka pala. Me ka hana kūpono, hāʻawi lākou i kahi palekana no nā ʻoihana e hōʻemi i nā kumukūʻai a hoʻonui i ka pono.
