Pehea e hana hou ai i nā mea hana Tungsten Carbide

undefined


Ua ʻike ʻia ʻo Tungsten carbide he tungsten alloy, cemented carbide, hard alloy, a me ka metala paʻakikī. Ua kaulana nā mea hana tungsten carbide i ka ʻoihana hou mai ka makahiki 1920. Me ke kaiapuni, puka mai ka hana hou ʻana o nā huahana tungsten carbide e hiki ai ke hoʻoulu i ke kumukūʻai a me ka pau ʻole o ka ikehu. Hiki ke ʻano kino a i ʻole ke ʻano kemika. ʻO ke ʻano hana kino ʻo ia ka wāwahi ʻana i nā mea hana tungsten carbide i ʻāpana, he paʻakikī ke ʻike a nui ke kumukūʻai ma muli o ka paʻakikī nui o nā mea hana tungsten carbide. No laila, ʻike pinepine ʻia nā mea hana ʻoki tungsten carbide i nā ʻano kemika. A e hoʻokomo ʻia ʻekolu mau ʻano kemika --- hoʻihoʻi hou i ka zinc, hoʻihoʻi electrolytic, a me ka unuhi ʻana e ka oxidation.


Hoʻihoʻi Zinc

ʻO Zinc kahi ʻano mea kemika me ka helu atomic 30, nona nā helu heheʻe o 419.5 ℃ a me nā wahi paila o 907 ℃. I ke kaʻina hana o ka hoʻihoʻi zinc, hoʻokomo ʻia nā mea ʻoki tungsten carbide i loko o ka zinc hoʻoheheʻe ʻia ma lalo o kahi kaiapuni o 650 a 800 ℃ mua. Hana ʻia kēia hana me ke kinoea inert i loko o ka umu uila. Ma hope o ka hoʻihoʻi ʻana o ka zinc, e hoʻoheheʻe ʻia ka zinc ma lalo o kahi mahana o 700 a 950 ℃. Ma muli o ka hoʻihoʻi hou ʻana o ka zinc, ua like ka pauka i hoʻihoʻi ʻia me ka pauka puʻupaʻa i ka like.


Hoʻihoʻi Electrolytic

Ma kēia kaʻina hana, hiki ke hoʻoheheʻe ʻia ka mea hoʻopili cobalt ma ka electrolyzing i ka ʻōpala o nā mea ʻoki tungsten carbide e hoʻihoʻi i ka tungsten carbide. Ma ka hoʻihoʻi ʻana i ka electrolytic, ʻaʻohe mea ʻino i ka tungsten carbide i hoʻihoʻi ʻia.


Wehe ʻia e ka ʻokiʻoki

1. Pono e ʻeli ʻia ka ʻōpala tungsten carbide e ka hui ʻana me nā mea hoʻokahe e loaʻa ai ka sodium tungsten;

2. Hiki ke mālama ʻia ka sodium tungsten me ka wai a ʻike i ka kānana a me ka ua e wehe i nā haumia e loaʻa ai ka sodium tungsten maʻemaʻe;

3. Hiki ke hoʻoheheʻe ʻia ka sodium tungsten i hoʻomaʻemaʻe ʻia me kahi reagent, hiki ke hoʻoheheʻe ʻia i loko o kahi solvent organik, e kiʻi i nā ʻano tungsten;

4. E hoʻohui i ka wai amonia wai a laila e unuhi hou, hiki iā mākou ke loaʻa ka ammonium poly-tungstate solution;

5. He mea maʻalahi ka loaʻa ʻana o ka ammonium para-tungstate crystal ma ka hoʻohemo ʻana i ka solution ammonium poly-tungstate;

6. Hiki ke calcined ka Ammonium para-tungstate a laila hoʻemi ʻia e ka hydrogen e loaʻa ai ka metala tungsten;

7. Ma hope o ka carburizing i ka tungsten metala, hiki iā mākou ke loaʻa ka tungsten carbide, hiki ke hana ʻia i nā huahana tungsten carbide like ʻole.


Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
