Pickling
Hana ʻia ka pepa pickling me ka pepa wela wela kiʻekiʻe e like me ka mea maka, a hoʻoneʻe ʻia ka papa oxide e ka ʻāpana pickling, ʻoki ʻia, a hoʻopau ʻia. ʻO ka huahana waena ma waena o nā papa, ma ke kumu o ka hōʻoia ʻana i ka maikaʻi o ka ʻili a me nā koi hoʻohana, hiki i nā mea hoʻohana ke hoʻemi pono i ke kumukūʻai kūʻai.
ʻO nā pono o nā lau pilahi
1. Maikaʻi ka maikaʻi o ka ʻili, no ka mea, ua wehe ʻia ka pālima hao oxide mai ka pā pickling wela, kahi e hoʻomaikaʻi ai i ka maikaʻi o ka ʻili o ke kila a hoʻomaʻamaʻa i ka wili, ka ʻaila a me ka pena.
2. Kiʻekiʻe dimensional pololei, ma hope o ka palahalaha, hiki ke hoʻololi i ke ʻano o ka pā i kekahi ʻano, a laila e hōʻemi ana i ka deviation o unevenness.
3. Hoʻomaikaʻi i ka hoʻopau ʻana i ka ʻili a hoʻonui i ka helehelena.

Kaʻina Hoʻomaʻemaʻe a me ka hopena
Ke hoʻohālikelike ʻia me ke ʻano pickling, maʻalahi loa ka ʻōnaehana hoʻomaʻemaʻe laser, ʻaʻohe pono pretreatment, a hiki ke hoʻokō ʻia ka hana hoʻomaʻemaʻe o ka lawe ʻana i ka aila, ka wehe ʻana o ka papa oxide a me ka wehe ʻana i ka ʻōpala i ka manawa like. E hoʻā wale i ka hāmeʻa e hoʻokuʻu i ke kukui, a laila hoʻomaʻemaʻe.
Hiki i ka ʻōnaehana hoʻomaʻemaʻe laser ke piʻi i ka pae hoʻomaʻemaʻe ʻoihana kiʻekiʻe loa o ka pae Sa3, aneane ʻaʻohe pōʻino i ka paʻakikī, hydrophilicity a me ka hydrophobicity o ka ʻili. ʻOi aku ka maikaʻi ma mua o ka pickling.
ʻO nā pono a me nā pōʻino
Ka Kaʻina Hana a me nā Koina Hana
Hoʻohālikelike ʻia me ka mea hana pickling me nā kaʻina hana ʻoi aku ma mua o hoʻokahi kakini, ua hoʻokō ka mea hoʻomaʻemaʻe laser i ke kaʻina hana maʻalahi loa a loaʻa i kahi pae hoʻokahi. Hoʻopōkole loa i ka manawa hoʻomaʻemaʻe a me ka lilo waiwai.
He koi koʻikoʻi ko ke ʻano pickling ma ke kaʻina hana: pono e hoʻoheheʻe ʻia ka mea hana e hōʻoia i ka maikaʻi o ka wehe ʻana i ka ʻōpala; mālama ʻia ka ʻike ʻana o ka hopena pickling no ka pale ʻana i ka mea hana mai ka ʻino ʻia ma muli o ka nui o ka nui o ka waikawa; mālama ʻia ka mahana e like me nā kikoʻī o ke kaʻina hana e pale i ka pōʻino i ka mea hana a ʻO nā mea hana ke kumu o ka corrosion; ʻO ka pahu pickling e waiho mālie i ka sludge, kahi e ālai ai i ka paipu mehana a me nā mea hoʻokele ʻē aʻe, a pono e wehe mau ʻia; Eia kekahi, pono e hoʻolohe i ka manawa pickling, ke kaomi injection, ka sputtering hana, nā mea hoʻopau, etc.
Hiki i ka hoʻomaʻemaʻe laser ke ʻike i ka hana naʻaupō a i ʻole ka hana unmanned ma hope o ka hoʻonohonoho ʻana i nā ʻāpana i ka wā mua.
Hoʻomaʻemaʻe a me ka Polusi Kaiapuni
Ma kahi o ka hopena hoʻomaʻemaʻe ikaika, ʻoi aku ka maikaʻi o ka ʻōnaehana hoʻomaʻemaʻe laser i ka ʻoi aku o ka hoʻomanawanui hewa.
ʻO ka oxygen macular, ʻulaʻula a me ka ʻeleʻele pinepine ma muli o nā hewa i ka hana ʻana o ke ʻano pickling, a kiʻekiʻe ka helu hōʻole.
Hōʻike ka hoʻokolohua laser hāʻule wai inā ʻoi aku ka supersaturated o ka hoʻomaʻemaʻe ʻana i ka laser, aia nō ia i ka luster metallic ikaika, ʻaʻole ia e hana i ka hydroxide a me nā mea haumia ʻē aʻe, ʻaʻole ia e hoʻopilikia i nā ʻano hana hou e like me ka welding.
ʻAʻohe pollution kaiapuni e like me ka wai ʻōpala a me ka slag i ke kaʻina holoʻokoʻa o ka hoʻomaʻemaʻe laser, ʻo ia ke ʻano hoʻomaʻemaʻe ʻōmaʻomaʻo.
Kumukuai Hui VS Kumu Hoololi
Pono ka mea paahana pickling i nā kemika e like me nā mea hoʻohana, no laila, ʻo ke kumukūʻai o ka ʻāpana ʻo ia ka hoʻemi ʻana o nā lako + kumu kūʻai.
ʻAʻole pono ka mīkini hoʻomaʻemaʻe laser i nā mea hoʻohana ʻē aʻe ma mua o ke kūʻai ʻana i nā lako. ʻO ke kumukūʻai ʻāpana ʻo ia ka depreciation o nā mea hana.
No laila, ʻoi aku ka nui o ka hoʻomaʻemaʻe ʻana a me ka lōʻihi o nā makahiki, ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka hoʻomaʻemaʻe laser.
Pono ka hoʻohui ʻana o ka laina hana pickling i nā kaʻina hana paʻakikī, a ʻaʻole like ka lakio o nā pickling agents no nā mea metala like ʻole, no laila ke koi nei ka laina hana hoʻololi i kahi kumukūʻai hoʻololi nui, a hoʻomaʻemaʻe ʻia ka mea metala i kahi manawa pōkole. hoʻokahi a ʻaʻole hiki ke hoʻololi maʻalahi.
ʻAʻohe kumu hoʻololi no ka hoʻomaʻemaʻe laser: ma hope o ka hoʻololi ʻana i nā ʻāpana polokalamu o ka mīkini hoʻomaʻemaʻe like, hiki ke hoʻokō i ka hopena o ka hoʻomaʻemaʻe ʻana i ka pā kila i hoʻokahi minuke a me ka alumini alumini i ka minuke aʻe. He mea maʻalahi no nā ʻoihana e hoʻokō i ka hana maʻalahi JIT.

Loaʻa i ka pā pickling kahi ākea ākea a hohonu hoʻi i ka hana ʻana i ka hana, a ke pāʻani nei i kahi hana maikaʻi i ke kākoʻo ʻoihana. Eia nō naʻe, me ka hoʻomau mau ʻana o ka ʻoihana hana, ke hoʻokō lohi ʻia nei ka hiki ke hoʻoponopono ʻia a me ka hoʻoponopono ʻana.
Me ka hoʻonui ʻana i ka ʻike kaiapuni o ka poʻe, ʻoi aku ka paʻakikī o ke aupuni a me nā ʻoihana no nā laina hana pickling, a ʻoi aku ka lahilahi o ka loaʻa kālā o nā ʻoihana pili. ʻOi aku ka maikaʻi o ke kaiapuni holoʻokoʻa no ka hoʻomaʻemaʻe laser.
Malia paha i loko o nā makahiki he ʻumi e hiki mai ana, loaʻa ka inoa hou o nā pepa pickling - nā pepa hoʻomaʻemaʻe laser.
