ʻOkoʻa: ke one garnet a me ka slag keleawe i ka sandblasting!

Ke one oneakepa keleawehoʻohana nui ʻia a kaulana hoʻi nā abrasive sandblasting. ʻIke ʻoe i ka ʻokoʻa ma waena o lākou no ka sandblasting?

1.Ke one oneHe kumu palekana ko ka sandblasting
Ke one onehe mea hao ʻole, ʻaʻohe silika manuahi, ʻaʻohe metala kaumaha. I ke kaʻina hana o ka sandblasting, ʻaʻohe ejection lepo, ʻoluʻolu a palekana; He metala kaumaha non-ferrous. ʻO ka puhi ʻana i ke one me ka pala keleawe he pōʻino paha i ka inhalation metala kaumaha i loko o ke kino.

2.Ke one onehe paakiki kiekie
I ka puhi ʻana i nā mea me ka paʻakikī kiʻekiʻe e like me ke kila kila,one oneʻoi aku ka pono. ʻO ka paʻakikī o ke one garnet ma waena o 7.0-8.0, a ʻoi aku ka haʻahaʻa o ka paʻakikī o ke keleawe. ʻO ke one Garnet he polyhedral, me nā kihi ʻoi aku ka maikaʻi, i ʻoi aku ka maikaʻi o ka sandblasting, Ma hope o ka sandblasting garnet, ʻaʻohe o nā peaks a me nā trouges i ka ʻili o ka mea hana, ʻo ka roughness o 30-75 microns, hiki ke hoʻokō i ka papa kiʻekiʻe loa Sa3 ʻO ke kūlana sandblasting, ʻaʻole hiki ke hoʻokō i kēlā hopena.

3.Garnet sandblasting hoʻonui i ke ola o ka uhi
He haʻahaʻa loa ka ʻike chloride o ke one garnet, a ʻaʻole e hana ʻia ka paʻakai soluble ma hope o ka sandblasting, hiki ke hoʻokō i ka adhesion o ka uhi no nā makahiki he nui. ʻOi aku ka nui o nā ʻāpana keleawe, a ʻoi aku ka kiʻekiʻe o ka chloride ma mua o ke one garnet. No laila, hiki i ka hoʻohana ʻana i ke one garnet ke hoʻonui i ke ola o ka uhi

4. kumu kūʻai haʻahaʻa o ke keleawe slag sandblasting
Ma keʻano he kumu kūʻai haʻahaʻa haʻahaʻa, kūpono no ka hoʻomaʻemaʻeʻana i ka hoʻomaʻemaʻe hoʻomaʻemaʻe, ka hoʻomaʻemaʻe wikiwiki a me ka maikaʻi o ka hoʻomaʻemaʻeʻana i ka lepo. ka hoʻohana ʻana i ke kumu kūʻai haʻahaʻa, ʻoiai a hiki i SA2.5

E like me ka hoʻohana ʻana i nā sandblasting ʻokoʻa a me nā hoʻolālā papahana, he mea nui e koho i nā abrasives sandblasting kūpono, e mālama i ke kumukūʻai a loaʻa i nā pono waiwai hou aʻe. Ua hoʻokumuʻia kā mākou hui i nā makahiki 19, pili nui ka hui i ka hana a me ke kaʻina hana a me ka maikaʻi o ka sandblasting abrasives, nā pilikiaʻenehana, eʻoluʻolu e hoʻokaʻaʻike mai iā mākou!
