Kucheneswa kwekucherekedza kwepavement yekumaka yekubvisa michina haingodzikisi kumanikidza kwemvura zvakajairika, nekuti jeti remvura rine simba rakanyanyisa simba uye simba rekucheka, bhandi rekuchenesa rakafara rabuda.Kuvakwa kwegirini kwakanakira.Mugwagwa wese uchange wakachena zvakanyanya.Kune zvakare midziyo yakanaka kwazvo inogona kunge iri nyore kufamba.Iko kushandiswa kwegarnet blasting abrasives kunowanzo kuderera uye kusashanda.Ichokwadi kuti mhedzisiro yekuchenesa jet yemvura iri nani.Kuti uite kuchenesa kukuru, kwete chete inogona kuvakwa chero nguva, shandisa high-pressure yemvura jet yekuchenesa tekinoroji, yekumaka mutsara kuchenesa, rudzi urwu rwejet inotakura jet simba ndiyo inonyanya kusashanda, kuitira kudzivirira kukanganisa uku. , mugwagwa wakacheneswa kwete chete hauna chero chiratidzo Kune zvakasara zve lacquer, mafuta emiriwo kana mamwe mafuta anodyiwa anofanira kushandiswa sepakati pekucheka makeke uye chokoti.Nekuda kwekuoma kwayo kwepamusoro, kusamira kwekusapfeka, uye makona akapinza.Iyo jeti haisati ichaganhurirwa kumvura nokuda kwepakati yayo, uye inowedzera zvikuru gakava.Mvura inonyungudusa shuga nyore uye inoparadza zvikafu izvi.Panguva imwecheteyo, hapazovi nekukuvadza, uye kubudirira kuchava nani.

Chechipiri, kubviswa kwependi yekumaka pendikunotevera kutamiswa kwemhuno.Mushure mekuwedzera garnet blasting abrasives, kuchengetedza kwezvakatipoteredza kunoshanduka chero nguva, iyo inowanzonzi yakakosha-yakaita muromo.Rectangles, nezvimwewo, zadzisa zvakasiyana-siyana zvekuchenesa zviratidzo.Kucheneswa kwejeti yemvura kwakafanana neyakanyorova nzira yejetblasting.Iyo yakajairika fomu yejeti mushure mekusiya muromo ndeye cylindrical jet.Inogona kudzika zvakananga mumapores easphalt kubvisa pende yekumaka.

Kutaura zvazviri, pasina pesvedzero yenguva, dzidziso yemugwagwa wekubvisa muchinainoshandisa majeti emvura ayo akakamurwa kuita mhando nhatu: discontinuous jets, pulse jets, cavitation jets.Mushure mekutora chikamu mugarnet abrasive blasting abrasive mujeti remvura, chinhu chinozivikanwa ndechekuti jeti inokanganisa chinangwa nenzira yemutsara.Semuyenzaniso, kana uchicheka chikafu chine shuga, iyo nozzle shape ichavawo nejeti rakaita sefan mushure mekushandura chimiro chemuromo.Kunze kwezvo, ikozvino nekuvandudzwa kwetekinoroji, Inofanirwa kunyatsotsanangurwa sejeti remvura.Isu tinowanzoti majeti emvura haakonzeri kuwanikwa kwemamwe majeti emvura.

Isu tinoziva kuti mukuputika kwakaoma uchishandisa muchina wejecha, mamwe mabhomba ane chimiro chakafanana akaonekwa zvakare munguva yakapfuura.Zvisinei, ine nzvimbo diki yehasha dzisingabatsiri pamusoro pechinangwa.Zvakadai se conical uye triangular.Mamwe majeti ekufambisa maapplication anodawo kushandiswa kwemulsion sepakati.
