ʻO ka ʻokoʻa ma waena o ke keleawe keleawe a me ke one garnet no ka sandblasting

1. ʻO nā waiwai kūʻokoʻa o ke one garnet a me ka slag keleawe

Ke one onehe mea abrasive maoli, i haku nui ʻia me nā silicates.Paʻa keleawehe koena o ka hoohehee keleawe, he emi ke kumukuai, aka, aole kiekie loa kona paakiki. ʻO nā hui metala i lokokepa keleawehe kaumaha, a komo paha kekahi mau ʻāpana i loko o ka substrate, e hoʻopōʻino ai i loko. Akā ma ke ʻano he abrasives, loaʻa iā lākou a pau nā ʻaoʻao ʻoi, a ma waena o ke one garnet he ʻano ʻano daimana 12 ʻaoʻao. I ka wā o ka sandblasting, hiki ke hoʻohana ʻia nā kihi ʻoi aku e ʻoki i nā haumia mai ka substrate, no laila e ʻoi aku ka maikaʻi o ka hopena.

Paʻa keleaweloaʻa i ka lākiō lepo kiʻekiʻe loa i ka wā e hoʻoneʻe ʻia ai ke one, a ʻilihune ka ʻāina sandblasting. Eia kekahi, ʻaʻole kiʻekiʻe loa ka hopena sandblasting, no laila hiki ke hana ʻia kekahi mau hana koʻikoʻi.Ke one oneua undergone 3 magnetic separations, 4 sieves, 6 wai holoi, a me 4 maloʻo pōʻaiapuni, i loaʻa nā mea maikaʻi i ka maʻemaʻe a hiki ke hoʻopau loa i nā mea haumia like ʻole ma ka ʻili o ka substrate, e hoʻokō i ka hopena sandblasting o SA3. No laila ma ke ʻano o ka pono, ʻoi aku ka maikaʻi o ke one garnet ma mua okepa keleawe.Ka nui a me ka nuipa okepa keleaweʻano nui nā ʻāpana (e lawe ana i ka huahana 30/60 # ma ke ʻano he laʻana, aia he 1.3 miliona mau ʻāpana no ka kilokani keleawe, ʻoiai ʻo ke one garnet he 11 miliona mau ʻāpana), no laila ka wikiwiki o ka pala keleawe.hoʻohuehue ʻanalohi ka hoʻomaʻemaʻe ʻana, a ʻoi aku ka nui o ke keleawe keleawe e pono e hoʻopau i kēlā me kēia ʻāpana.

3. Hoʻohālikelike kumu kūʻai o nā abrasives sandblasting

Hoʻohālikelike ʻia meʻO ka palapa keleawe,ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ke one garnet, akā ma ke ʻano o ka hoʻohana hou ʻana, ma muli o kona paʻakikī kiʻekiʻe, hiki ke hoʻohana hou ʻia ke one garnet ma mua o 3 mau manawa, ʻo ia ka mea e haʻahaʻa loa ke kumukūʻai o ka hoʻohana hoʻokahi ma mua o nā abrasives ʻē aʻe.Paʻa keleaweHe haʻahaʻa ke kumu kūʻai, akā ua lohi ka wikiwiki o ka sandblasting, a ʻo ke kumukūʻai o ka hoʻohana ʻana i ke one no kēlā me kēia mika square ma kahi o 30-40% kiʻekiʻe ma mua o ke one garnet.

Paʻa keleawehe lepo kiʻekiʻe a loaʻa kekahi mau mea haʻahaʻa haʻahaʻa, hiki ke hoʻoulu i ka lepo ma luna o ka hana. Nui nō hoʻi ka lepo ma ka ʻili o ka sandblasting, kahi e pono ai ka hoʻomaʻemaʻe lua.Paʻa keleaweloaʻa i nā mea ʻino, a hiki i ka hoʻohana lōʻihi ke hana i nā maʻi ʻoihana hiki ʻole ke kāohi ʻia no nā limahana - silicosis. I kēia manawa, ʻaʻohe hopena maikaʻi.
