Hana ʻia ke kila kila me ka chrome alloy mea i hoʻokahe wikiwiki ʻia ma hope o ka hoʻoheheʻe ʻana. Ma hope o ka mālama ʻana i ka wela, ua hōʻike ʻia me nā hiʻohiʻona mechanical maikaʻi loa, ke kūpaʻa maikaʻi, ke kūpaʻa luhi kiʻekiʻe, ke ola hana lōʻihi, ka ʻai haʻahaʻa a pēlā aku. 30% e mālama ʻia. Hoʻohana nui ʻia i ka ʻoki granite, sandblasting a me ka pana peening.
Hana ʻia ke kila kila me ke kila kalapona hao, hoʻohana ʻia e hana i nā pōpō, nā wili a me nā apo apo. He kiʻekiʻe a kūlike ka paʻakikī o ka lawe ʻana i ke kila a me nā manawa pōʻai kiʻekiʻe, a me ka elasticity kiʻekiʻe. ʻO ke kūlike o ka hui kemika, ka ʻike a me ka hāʻawi ʻana i nā inclusions non-metallic a me ka hāʻawi ʻana i nā carbide o ke kila kila, ʻo ia kekahi o nā koi kiʻekiʻe i ka hana kila a pau.
Loaʻa i ke kila kila ka metala makamae - chromium, ma o ke kaʻina hana kūʻokoʻa, ka hoʻolālā metallographic maikaʻi loa, nā ʻāpana huahana piha, ka paʻakikī like ʻole, nā manawa pōʻai kiʻekiʻe, hiki ke hoʻomaikaʻi maikaʻi i ka helu hoʻihoʻi (abrasive i ke kaʻina o ka hoʻoheheʻe ʻana i ke one e hoʻemi iki ʻia), no laila e hōʻemi i ka hoʻohana ʻana o ka abrasive a hiki i 30%.
Lawe i ke kila kila no ka puhi ʻana i ke one
ʻO ka lawe ʻana i ke kila grit maikaʻi i hoʻohana ʻia no ka pauku ʻana o ke kino e pili pono ana i ka maikaʻi a me ke kumu kūʻai piha e pili ana i ka maikaʻi o ka puhi ʻana i ke one, ka uhi ʻana i ke one, ka pena pena, ka ikehu kinetic a me ka hoʻohana abrasive. Me ka hoʻokuʻu ʻana i ka maʻamau o ka pale ʻana i ka uhi ʻana (PSPC), aia kahi noi kiʻekiʻe i ka maikaʻi o ka puʻu one. No laila, he mea koʻikoʻi ka maikaʻi o ke kila kila i ka puhi ʻana i ke one.
ʻO nā granules angular no ka pahu one sandblasting
ʻO ka pahū ʻana o ke one granules ma ka pahu pahu pahu ma hope o ka wili ʻana. E hoʻomaʻemaʻe i ka hui welded a i ka manawa like e hana i ka ʻili o ke kino pahu i kekahi ʻano ʻino a hoʻonui i ka hopena anti-corrosion pena, i hiki ke hana no ka manawa lōʻihi ma waena o nā moku, nā chassis, ka kaʻa ukana a me na kaa alahao.
ʻO ka ʻeleʻele kila angular no ke kahua uila uila sandblasting.
Loaʻa i ka huahana uila kahua ka noi kikoʻī no ka roughness a me ka maʻemaʻe o ka mālama ʻana i ka ʻili. Ma hope o ka hoʻomaʻamaʻa ʻana i ka ʻili o ke kila kila, pono lākou e hoʻololi i nā ʻano loli i waho no ka manawa lōʻihi. No laila, ʻoi aku ka pivotal o ke one angular grit blast no ka ʻili.
ʻOki kila kila a me ka ʻoki pōhaku
E ʻoki pōhaku me ka hoʻohana ʻana i ka ʻoki kila pōhaku a me ka ʻoki ʻoki pōhaku mai ke kahe wai. I ke kaʻina o ka ʻoki ʻana, ʻaʻohe hoʻololi kemika a me ka maikaʻi o ke aloha ʻole i ka hana kemika a me ke kino o nā mea pōhaku, ʻaʻohe deformation wela, lancing liʻiliʻi, precision kiʻekiʻe, ʻokiʻoki maʻemaʻe, maʻemaʻe a ʻaʻohe pollution, etc.
ʻO ke kila angular Grit no nā Locomotives ke puhi ʻana i ke one
Ma hope o ka hoʻopau ʻana i ka hana ʻana a i ʻole ka hoʻoponopono hou ʻana, pono e pena ʻia ka ʻili o ka locomotives (me ka undercoat, ka uhi waena, ka hoʻopau ʻana a me nā mea ʻē aʻe), e hoʻomaikaʻi i ka locomotive i waho a me ke ola hana. ʻO ke koho ʻana i ke kila angular Grit he mea koʻikoʻi loa ia i ka mālama ʻana i ka ʻili, e pili ana i ka hana o ka uhi ʻana o ka anti-crack, ke kū ʻana o ke komo ʻana a me ka inoxidizability.
ʻO ke kila kila no ka hale kila
I ka hale kila, pili ka wikiwiki o ka corrosion i ka haʻahaʻa pili o ka ea a me ka hoʻohui ʻana a me ka nui o ka pollutant i ka lewa. I mea e hoʻolōʻihi ai i kona ola lawelawe, pono ka hana kila ʻo Angular steel grit blasting surface treatment, a laila ma ke kāpī ʻana e hana i ke kiʻi pale ma ka ʻili metala e pale a hōʻemi i ka corrosion metala.
Mea Hana Hana no ka Mīkini Awa ke one
Hoʻohana nui ke kūkulu ʻia ʻana o ka uapo i ka hale kila. No laila, kiʻekiʻe loa ka noi anti-corrosion o ke kila. Hoʻohālikelike pinepine ka mīkini awa me kekahi kaiapuni kūikawā. No ka laʻana, ʻo ke ʻano o ka ea moana maʻemaʻe, ʻo ia ke kumu o ke kūkulu ʻia ʻana o ke kila e ʻeha hohonu. No laila, he mea koʻikoʻi ka hana ʻana i ke kila kila maikaʻi.
