Nā Kumu Koho ʻana i nā ʻāpana o ka Sandblasting
Nā Kumu Ke koho ʻana i nā Mea o Sandblasting
ʻO ke one ka mea abrasive maʻamau i hoʻohana ʻia i kēia kaʻina hana, no laila ka inoa sandblasting. I nā makahiki he 50 i hala iho nei, ua hoʻololi ʻia nā mea hou aku no ke kaʻina hana hoʻomaʻemaʻe.
I kēia mau lā, ʻoi aku ka pololei o nā huaʻōlelo media blasting a me abrasive blast cleaning i ke kaʻina hana, no ka mea, hiki i nā mea pahū ke hoʻokomo i kekahi helu o nā huahana, e like me ka lanahu, garnet, nā kīʻaha aniani, nā pūpū wōnati, a me nā ʻōpala.
Hiki ke hoʻohana ʻia ka pāpaʻi pāpaʻi ma nā ʻāpana āpau o ka tractor, hāʻawi ʻia i ka hui kūpono o nā mea media, ke kaomi ea, ka leo, a me ka nozzle puhi.
Eia kekahi mau mea maʻamau i ke koho ʻana i nā ʻāpana.
Ka Compressor
ʻO ka ea compressor ka mea nui loa o ka hana sandblasting. Hāʻawi ia i ka nui o ka ea a me ke kaomi e hoʻoneʻe i ka media abrasive ʻoiai ʻo ka hose a me ka nozzle blast me ka wikiwiki e wehe i ka unahi, ka ʻōpala, a i ʻole nā pale kahiko mai ka ʻili i kuhi ʻia.
No ka hoʻoheheʻe ʻana o ke Kuhina, 3 a 5 cubic kapuaʻi i kēlā me kēia minuke (cfm) hiki ke lawa, wahi āna. No nā hana nui aʻe, pono paha ka laulā o 25 a 250 cfm.
Ke koho ʻana i ka ipu hao a i ʻole ke keʻena keʻena, ʻelua ʻano e koho ai: ka meaʻai suction a me ka hānai kaomi.
Pūnaehana hānai
Hoʻohana ʻia nā ʻōnaehana hoʻoheheʻe ʻana ma o ka huki ʻana i nā abrasive i loko o ka pū puhi. Ke hilinaʻi nei kēia i ka ea compressor e hāʻawi ʻia i loko o ka pū puhi e hana ai i kahi ʻōpala. Ke hoʻāla ʻia ka pū, hoʻomohu ʻia ka abrasive i loko o ka laina hānai i ka pū puhi. Lawe ka ea pakele i ka abrasive i ka ʻili i hoʻopaʻa ʻia.
ʻO ka ʻokoʻa, mālama nā ʻōnaehana kaomi-feed i ka abrasive i loko o ka ipu a i ʻole ka ipuhao. Ke hana nei ka ipuhao ma ke kaomi e like me ka hose mea. Hoʻonoho ʻia kahi pahu hoʻomalu ma lalo o ka ipu hao i ka abrasive i loko o kahi kahawai ea wikiwiki. Lawe ke kahawai ea i ka mea abrasive ma o ka hose pahū i ka ʻili hana.
ʻO ka blast nozzle ka mea i hoʻohana ʻia e hoʻonui i ka wikiwiki o ka hopena o ka sandblasting abrasive. ʻOiai he nui nā ʻano nozzles, ʻehā mau mea maʻamau.
* Hoʻokumu ka nozzle wili pololei i kahi ʻano paʻa no ka hoʻomaʻemaʻe wahi a i ʻole ka pahu pahu. Hoʻohana mau ia no ka hoʻomaʻemaʻe ʻana i nā ʻāpana liʻiliʻi.
* ʻO ka nozzle venturi ka koho maikaʻi loa no ka hoʻomaʻemaʻe kiʻekiʻe o nā papa nui. He mea nui e hoʻomaopopo, akā naʻe, i ka wā e puhi ai i nā kaomi kiʻekiʻe (100 psi a ʻoi aku paha), hiki i nā abrasives ke piʻi i ka wikiwiki o ka 500 mph.
* Hiki ke noʻonoʻo ʻia ka nozzle lua-venturi blast e like me ʻelua mau nozzles i hoʻonoho ʻia i kēlā me kēia hopena. ʻO nā puka ea-induction i loko o ke kino o ka nozzle e ʻae i ka ea compressor e hui pū me ka ea lewa. Hoʻonui kēia hana venturi i ka cfm a hoʻonui hoʻi i ka nui o ke ʻano pahū. Hoʻomaopopo ʻo Deardorff ʻo ka nozzle pālua-venturi ka koho maikaʻi loa no ka hoʻomaʻemaʻe haʻahaʻa haʻahaʻa. ʻO kēia no ka mea hiki i ka hana hoʻoheheʻe ʻana o nā lua hoʻokomo i ka ea ke lawe i ka nui o nā abrasive koʻikoʻi ma o ka hose mea ma ke kaomi haʻahaʻa.
* Hoʻopuka ka nozzle peʻa i kahi hiʻohiʻona peʻa i hoʻohana ʻia no ka puhi ʻana i nā ʻili ākea ākea. Pono ka nozzle fan i ka nui o ka ea cfm no ka hana.
Loaʻa nā nozzles me kahi koho o nā mea lining, ʻo ia ka alumini, tungsten carbide, silicon carbide, a me boron carbide. Ma keʻano maʻamau, pili ka koho i kāu kālā a me ka paʻakikī o ka hana. E hoʻomanaʻo wale i ka piʻi ʻana o ka hoʻohana ʻana i ka media me ka lole nozzle.
Nā mea a pau e pili ana i nā Abrasive
ʻO nā kumu e pili ana i ka hana abrasive e like me kēia.
* ʻO ka paʻakikī o ka grime, corrosion, a i ʻole nā palapala kahiko e wehe ʻia.
* ʻO ka haku mele ʻana a me ka naʻau.
* Pono ka maikaʻi o ka hoʻomaʻemaʻe.
* Ke ʻano o ka abrasive.
* ʻO ke kumukūʻai a me ka hoʻopau ʻana.
* Hiki ke hana hou.
ʻO ka abrasive ka ʻāpana o kēlā me kēia kaʻina hana e hana maoli i ka hana hoʻomaʻemaʻe. ʻEhā mau papa helu nui no nā mea abrasive.
* Loaʻa i nā mea abrasive kūlohelohe ke one silica, ke one mineral, ka garnet, a me ka hematite specular. Manaʻo ʻia kēia mau mea abrasive hiki ke hoʻopau ʻia a hoʻohana nui ʻia no ka puhi ʻana i waho.
* ʻO nā mea abrasive i hana ʻia e ke kanaka a i hana ʻia paha, e like me nā pahu aniani, ka alumini oxide, ka silicon carbide, ka pana kila, a me ka pāpaʻi plastik, hiki ke hoʻohana hou ʻia a hiki ke hoʻohana ʻia i nā ʻōnaehana e hiki ai ke hoʻihoʻi a hana hou.
* ʻO nā mea abrasive o nā huahana - e like me ka lanahu, he huahana ia o nā mea kanu uila i puhi ʻia i ka lanahu - ua manaʻo ʻia ʻo ia ka mea hoʻohana nui ʻia ma hope o ke one silica.
* Hoʻokaʻawale ʻia nā mea abrasive non-metallic e like me nā mea kūlohelohe. Loaʻa kēia mau mea i nā ʻeke aniani, nā pāpaʻi palaka, a me nā ʻano kīʻaha e like me ka corncobs, ka maloo palaoa, nā pūpū pecan, nā pūpū niu, a me nā pūpū wōnati. Hoʻohana ʻia nā abrasive organik ke koi ʻia ka pōʻino liʻiliʻi.
ʻAno a me ka paʻakikī
ʻO nā manaʻo ʻē aʻe i ke koho ʻana i kahi abrasive ʻo ke ʻano kino a me ka paʻakikī.
"ʻO ke ʻano o ka abrasive ka mea e hoʻoholo ai i ka maikaʻi a me ka wikiwiki no ke kaʻina hana pahū," wahi a Deardorff. "E hoʻomaʻemaʻe wikiwiki ʻia nā ʻāpana ʻokiʻoki, ʻoi, a ʻano like ʻole paha i ka ʻili.
ʻO ka paʻakikī, ʻo ia hoʻi, ʻaʻole pili wale i ka wikiwiki e hoʻomaʻemaʻe ai, akā i ka nui o ka lepo i hana ʻia a me ka helu haʻihaʻi, a he hopena pololei hoʻi i ka hiki ke hana hou.
Hoʻokaʻawale ʻia ka paʻakikī o kahi abrasive e ka helu Mohs - ʻoi aku ka kiʻekiʻe o ka helu mai 1 (talc) a 10 (diamond), ʻoi aku ka paʻakikī o ka huahana.
