Nā kaʻina hana o ka hana ʻana i nā pihi Carbide
Nā kaʻina hana o ka hana ʻana i nā pihi Carbide
ʻO Tungsten carbide kekahi o nā mea honua i hoʻohana ʻia i ka ʻoihana. Hana ʻia ka pihi carbide mai ka tungsten carbide, no laila aia nā waiwai o ka carbide cemented. ʻO ke ʻano cylinder o nā pihi pihi tungsten carbide e maʻalahi ke hoʻokomo i loko o nā mea hana ʻē aʻe ma o ka hoʻokomo ʻana i ka wela a me ke kaomi anu. Ma muli o ka paʻa ʻana o ke pihi carbide i nā waiwai o ka paʻakikī, ka paʻakikī, a me ka lōʻihi, he mea maʻamau ka ʻike ʻana iā lākou ma nā ʻano like ʻole e like me ka wili luawai, ka wili pōhaku, ka hana alanui, a me ka hanana mining. Akā pehea ka hana ʻana o ke pihi carbide? Ma kēia ʻatikala, e noʻonoʻo mākou i kēia nīnau.
1. Hoʻomākaukau Mea Maka
Pono nā kaʻina hana i nā mea WC pauka a me Cobalt pauka. Hana ʻia ka pauka WC me nā ores tungsten, ʻeli ʻia a hoʻopaʻi ʻia mai ke ʻano. E ʻike ʻo Tungsten ores i nā ʻano hopena kemika, ʻo ka mua me ka oxygen e lilo i tungsten oxide a laila me ke kalapona e lilo i pauka WC.
2. Huihui Pauda
Eia ka hana mua e hana ai nā hale hana i nā niho carbide. E hoʻohui nā hale hana i nā mea hoʻopaʻa (Cobalt powder a i ʻole Nickel powder) i ka pauka WC. ʻO nā mea paʻa e like me ka "glue" i ko mākou ola i kēlā me kēia lā e kōkua i ka hoʻohui ʻana i ka tungsten carbide paʻa loa. Pono nā mea hana e hoʻāʻo i ka pauka hui ʻia e hōʻoia i hiki ke hoʻohana i nā pae aʻe.
3. wili pulu pulu
I loko o kēia kaʻina hana, e hoʻokomo ʻia ka pauka hui ʻana i loko o ka Mīkini Ball Milling a wili ʻia me ka wai e like me ka wai a me ka ethanol. ʻAʻole e hana kemika kēia wai akā maʻalahi ka wili.
4. Kapu maloo
Hana mau kēia kaʻina hana i kahi mea maloʻo. Akā hiki i nā hale hana like ʻole ke koho i nā ʻano mīkini like ʻole. He mea maʻamau nā ʻano mīkini ʻelua. ʻO kekahi ʻo Vacuum Dryer; ʻo kekahi ʻo Spray Drying Tower. Loaʻa iā lākou ko lākou pono. E kāpī i ka hana hoʻomaloʻo me ka wela nui a me nā kinoea inert e hoʻoheheʻe i ka wai. Hiki iā ia ke hoʻoheheʻe i ka hapa nui o ka wai, ʻoi aku ka maikaʻi o kēia mau kaʻina hana ʻelua ʻo Pressing and Sintering. ʻAʻole pono ʻo Vacuum Drying i kēlā wela kiʻekiʻe akā he pipiʻi a nui ke kumukūʻai no ka mālama ʻana.
5. Ke kaomi ana
No ke kaomi ʻana i ka pauda i nā ʻano ʻano like ʻole e pono ai nā mea kūʻai aku, e hana mua nā limahana i ka poni. Hiki mai nā pihi Carbide i nā ʻano like ʻole no laila hiki iā ʻoe ke ʻike i nā ʻano make like ʻole, me ke poʻo conical, ke poʻo pōpō, ke poʻo parabolic, a i ʻole ke poʻo puna, me hoʻokahi a ʻelua paha chamfers, a me ka ʻole a i ʻole nā puka pinhole. ʻElua mau ʻano hana. No ka liʻiliʻi liʻiliʻi o nā pihi, e paʻi nā mea hana e kahi mīkini ʻakomi; no ka mea ʻoi aku ka nui, e paʻi nā limahana e kahi mīkini kaomi hydraulic.
6. Hoʻopaʻa ʻia
E kau ka poʻe hana i nā ʻōlelo aʻoaʻo bit carbide kaomi ma luna o ka pā graphite a i ka Hot Isostatic Pressing (HIP) Sintered Furnace ma lalo o ka mahana o kahi o 1400˚ C. Pono e hoʻokiʻekiʻe ʻia ka mahana ma kahi wikiwiki haʻahaʻa i emi mālie ke pihi carbide a pau. ʻoi aku ka maikaʻi o ka hana pihi. Ma hope o ka sintering, e emi iho a ʻaneʻane ka hapalua o ka nui o ka leo ma mua.
7. Nānā maikaʻi
He mea nui ka nānā ʻana i ka maikaʻi. E nānā mua ʻia nā mea hoʻokomo Carbide no nā waiwai e like me ka paʻakikī, ka cobalt magnetic, a me ka microstructure e nānā i nā lua a i ʻole nā māwae liʻiliʻi. Pono e hoʻohana ʻia kahi micrometer e nānā i kona nui, kiʻekiʻe, a me ke anawaena ma mua o ka hoʻopaʻa ʻana.
I ka hōʻuluʻulu ʻana, pono e hahai i nā kaʻina hana no ka hana ʻana i nā pihi tungsten carbide cemented:
1. Hoʻomākaukau Mea Maka
2. Huihui Pauda
3. wili pulu pulu
4. Kapu maloo
5. Ke kaomi ana
6. Hoʻopaʻa ʻia
7. Nānā maikaʻi
No nā hana hou aku a me ka ʻike, hiki iā ʻoe ke kipa www.zzbetter.com.
