He aha nā waiwai a me nā hoʻohana o nā abrasives pūpū walnut kiʻekiʻe?
Pono e hana ʻia nā mea hoʻopailua hull kiʻekiʻe mai nā pūpū hickory kiʻekiʻe e like me nā mea maka, i kuʻi ʻia, hoʻopili ʻia, mahu ʻia a holoi ʻia, mālama ʻia me nā lāʻau lapaʻau a hana ʻia ma o nā kānana he nui. ʻAʻole wale ka mea hoʻopailua pūpū Walnut i ke kapa komo a me ke kaomi, akā ʻaʻole hoʻi e d...E heluhelu hou aku -
He aha ke ala maikaʻi loa e lawelawe a mālama ai i ka alumina keʻokeʻo i hoʻopili ʻia?
He mea nui ka alumina keʻokeʻo i hoʻohana ʻia ma nā ʻoihana he nui e like me nā abrasives, refractories, a me nā keramika. He mea waiwai nui ia no kona paʻakikī a me ke kūpaʻa, e lilo ia i koho kaulana no nā noi he nui. I mea e hōʻoia ai ua mālama pono ʻia a mālama ʻia ka mea, aia kahi...E heluhelu hou aku -
Ke piʻi nei ke koi no ka alumina keʻokeʻo i nā noi ʻoihana
I ka hoʻonui ʻana o nā ʻoihana ma ka honua holoʻokoʻa i ka hana ʻana a ke hoʻomau nei ka ulu ʻana o ke koi no nā mea paʻa, ua puka mai ka alumina fused keʻokeʻo (WFA) ma ke ʻano he mea abrasive no nā mea hana ma nā wahi āpau. He mea abrasive kiʻekiʻe ka WFA i hana ʻia ma ka hoʻoheheʻe ʻana i ka alumini kiʻekiʻe i loko o kahi umu uila...E heluhelu hou aku -
Nā noi o ka pauka alumina ultrafine
He mea nui ka alumina maikaʻi loa no nā keramika hana. ʻO ka pauka alumina maikaʻi loa xz-L20, ka nui o ka ʻāpana 100 nm, keʻokeʻo ke kala, 99% o ka ʻike paʻa. Hiki ke hoʻohui ʻia i nā resins wai like ʻole, i loko o nā resins aila, nā mea hoʻoheheʻe a me nā ʻōpala ma kahi pae hoʻohui o 3%-5%, hiki ke...E heluhelu hou aku -
ʻO ka ʻokoʻa ma waena o ka alumina i hoʻoheheʻe ʻia keʻokeʻo a me ka alumina i hoʻoheheʻe ʻia ʻeleʻele
ʻO ka alumina keʻokeʻo i hoʻoheheʻe ʻia a me ka alumina ʻeleʻele i hoʻoheheʻe ʻia he ʻelua mau mea abrasives i hoʻohana pinepine ʻia. ʻAʻole ʻike ka nui o ka poʻe i ka ʻokoʻa pololei ma waena o nā mea ʻelua koe wale nō ke kala. I kēia manawa e lawe wau iā ʻoe e hoʻomaopopo. ʻOiai aia nā alumina i loko o nā mea abrasives ʻelua, ʻoi aku ka nui o ka alumina o ka alumina keʻokeʻo i hoʻoheheʻe ʻia ma mua o 99%, a...E heluhelu hou aku -
ʻO ka ʻokoʻa ma waena o ka alumini oxide a me ka alumina oxide calcined
He mea inorganic ka aluminium oxide me ke ʻano kemika A1203, he hui paʻakikī loa me kahi kiko heheʻe o 2054°C a me kahi kiko paila o 2980°C. He kristal ionic ia e hiki ke ionized i nā mahana kiʻekiʻe a hoʻohana pinepine ʻia i ka hana ʻana i nā mea refractory. Calcine...E heluhelu hou aku
