ʻAʻole mākou e ʻōlelo pinepine i ka huaʻōlelo sandblasting i kēlā me kēia lā, akā pili ia i nā mea āpau o ko mākou ola. No lailaʻike maoli ʻoe i ka meahoʻolele ʻana i ke one? No ka kama'āina iā ia, he mea kōkua kēia hoʻolauna mua iā ʻoe. 

ʻO ka hoʻoheheʻe ʻana

Brief Hoʻolauna

Abrasive bmau ka hana ohoʻopau ʻilima ka paipai anamediamaa kiʻekiʻe ka wikiwiki e pili ana iā ia. He wikiwiki amaʻalahiala e wehe ainā mea hoʻohaumia ilimai metala, pulupulu,a i ʻole ka plastic.

Hoʻohana pinepine ʻia ka hoʻoheheʻe abrasive ma nā wahi paʻa e like menā keʻena pahū a i ʻole nā ​​keʻena, a i ʻole ma nā wahi ākea e like me ka waʻa, hale, a me ke alahaka, etc.

ʻO nā ʻano

Sandblasting

Hoʻolauna pōkole

Me heʻano ʻano ʻO ka pahū abrasive, ʻo ka sandblasting kahi kaʻina hana mālama ʻili i loaʻa i ka ea compressor, abrasive particles, a me ka nozzle e pīpī i nā ʻāpana abrasive ma lalo o ke kahe o ka ea i ke kaomi kiʻekiʻe. Kapa ʻia ʻo ia he sandblasting no ka mea pahū me nā ʻāpana one. Ke kāpī ʻia nā ʻāpana one i ka ʻili, hana lākou i ka mea i makemake ʻia.

ʻO ka mōʻaukala o ka sandblasting a me nā nozzles

ʻO ka sandblasting kahi mea ʻikehiki mai ana maʻano, ʻaʻole he mea hana kanaka. No laila, inā makemake mākouikeke ʻike ʻia ka sandblasting, hiki ke ʻimi ʻia i ka hoʻomaka ʻana o kahānauo ka honua. lepo, one,a i ʻole ʻāpanapuhi ʻiae ka makani hiki kehoololika ili o kekahi mea ma ka hopena. E lawe i kahi laʻana i loko o ko mākou ola, ka makani ʻino.

I ka makahiki 1980, he kanaka i kapa ʻia ʻo BenjaminNahu Tilghmanʻike ʻia kēia hanana kūlohelohe ia ia i nana aku ai i na puka makani me ke one i puhi ia e ka makani. Eia kekahi, ua hoʻolālā ʻo ia i kahi mīkini hiki ke hoʻoneʻe i nā ʻāpana one ma ke kaomi ʻana i ka ea i ka ʻili o nā mea. ʻO ia ka mīkini sandblasting mua i kapa ʻia ʻo ka nozzle bore pololei.

Ua ʻike ʻo Daniel Bernoulli ka mea makemakika a me ka physicist Swiss i ka tHiki i ka ʻokoʻa o ka ea ke hoʻonui i ka wikiwiki o ke kahe abrasive, i kapa ʻia ʻo Bernoulli’s Kumu.

A laila, i ka makahiki 1700, ua hoʻohui ʻia kēia kumu e ka mea lapaʻau ʻItalia ʻo Giovanni Battista Venturi. A hiki i ka makahiki 1950, ʻo ka VenturUa ʻike ʻia nā nozzles ʻoiai ke ola nei ka hopena Venturi ma mua.

Nā ʻano maʻamau o nā Nozzle Sandblasting

No nā makahiki he nui, nā ʻano like ʻoleUa hana ʻia nā nozzles e like me ke kois. No ka mealaʻana, kaʻO ka nozzle venturi ka koho maikaʻi loa no ka hoʻomaʻamaʻa ʻana i ka sandblasting. ʻO kapāhū paipu lokonozzleishoohana nui iamaopopoka ilii lokoka paipu.ʻO ka bHoʻohana nui ʻia ka nozzle anana no ka hoʻomaʻemaʻe ʻana i nā wahi haiki a paʻakikī paha e lawelawe me ka nozzle maʻamaus.

Nozzle Venturi: Hōʻike ʻia nā nozzles Venturi i kahi hiʻohiʻona pahū ākea e hoʻoikaika maikaʻi i ka puhi ʻana. ʻO ke Kumukānāwai ʻo ka hoʻemi ʻana i ke kaomi o ka wai e alakaʻi i ka piʻi ʻana o ka wai’s ka wikiwiki.

Nozzle Induction Wai: Hōʻike ʻia ia e ka wai e hui pū ana i nā ʻāpana abrasive a me ka wai no ka mālama ʻana i ka ʻili. Hoʻohālikelike ʻia me nā nozzles ʻē aʻe, ʻoluʻolu ia i ke olakino no ke kāohi ʻana i ka lepo.

Nozzle Pahu Paipu Kuloko: Hoʻohana nui ʻia e hoʻomaʻemaʻe i ka paia o loko o ka paipu e pahū ana i kahi ʻano cone.Loaʻa nā ʻano nozzles like ʻoleno ka meaʻokoʻa nā anawaena o loko o ka paipu. I kekahi manawa pono nā mea hana hou, e like me nā pūʻulu kola, kaʻa kikowaena, a me ke kaʻa poʻo puhi.

Nozzle Piʻi Maiʻa: Kona’ ʻae ʻia ke kihi ʻāwili no ke komo ʻana i ka sandblasting i nā wahi paʻa a paʻa paha. ʻO iaHe koho maikaʻi ia no nā wahi haiki a paʻakikī paha ke lawelawemaʻamaunā nozzles
