Unoziva here sandblasting? –Sumo pfupi yejecha 

Kuputika kwejecha kunozivikanwawo sekunge abrasive blasting, chiito chekufambisa zvimedu zvakanyanyonaka zvechinhu chinokwesha pamhepo yakakwira kuenda pamusoro kuti chicheneswe kana kuchinatsa. Kupedzwa kwepamusoro kunosanganisira kushandiswa kwemuchina une simba (air compressor) pamwe nejecha rinoputika muchina  kupfapfaidza zvidimbu zvinokuvadza pasi pekumanikidzwa kwakanyanya pamusoro pepamusoro. Inonzi "sandblasting" nekuti inoputika pamusoro nezvikamu zvejecha. Kana zvidimbu zvejecha zvichirova pamusoro, zvinogadzira kutsetseka uye kuenzana.

Kushandiswa kweSandblasting

Sandblasting ndiyo imwe yenzira dzakanakisa dzekuchenesa nekugadzirira nzvimbo. Vehuni, machini, makanika emotokari, uye nezvimwe vese vanogona kushandisa jecha mubasa ravo, kunyanya kana vachinyatsonzwisisa nzira dzakawanda dzinogona kushandiswa nejecha.

1. Bvisa Ngura uye Corrosion:Kunyanya kushandiswa kwemedia uye jecha blasting ndeyekubvisa ngura uye ngura. Majecha anogona kushandiswa kubvisa pendi, ngura, uye zvimwe zvinosvibisa pamusoro kubva kumotokari, dzimba, muchina, uye chero imwe nzvimbo.

2. SurfacePretreatment:Sandblasting uye media blasting inzira yakanaka yekuita kuti nzvimbo igadzirire pendi kana kupfekwa. Munyika yemotokari ndiyo yakasarudzika nzira yekuridza midhiya chassis karepoda kupfekait. Iyo yakanyanya hutsinye midhiya senge aruminiyamu oxide inosiya chimiro chepamusoro icho chinonyatso batsira iyo jasi rehupfu kunamatira zvirinani. Ichi ndicho chikonzero vazhinji vanopfeka hupfu vachida zvinhu kuti zviputirwe midhiya isati yaputirwa.

3. Kugadziridzwa kwezvikamu zvekare:gadziridzo uye kuchenesa zvese zvinofamba zvakaita semota, midhudhudhu, michina yemagetsi, nezvimwewo, vatinoshanda navo vanobvisa kushushikana kwekuneta uye kuwedzera hupenyu hwebasa.

4. Gadzira Tsika Mamiriro uye Artwork: Kune mamwe-akakosha-chinangwa zvidimbu zvebasa, sandblasting inogona kuwana akasiyana maratidziro kana matt. Zvakadai sekukwenenzverwa kwesimbi yesimbi isina tsvina uye mapurasitiki, kukwenenzverwa kwejade, mating epamusoro pefenicha yemapuranga, patani pamusoro pegirazi rine chando, uye mameseji epamusoro pejira, nezvimwe. 

5. Smoothing rough Casting nema edges:Dzimwe nguva midhiya blasting inogona kunyatso kutsvedzerera kana semi-polish nzvimbo inenge yakaoma. Kana uine rough casting ine micheto yakapinza kana isina kujairika unogona kushandisa media blaster ine girazi rakapwanyika kutsvedzerera pamusoro kana kupfavisa muromo unopinza.

Iyo Sandblasting Inoitwa

Iyo sandblasting setup inowanzo umbwa nezvikamu zvitatu zvikuru:

·Sandblasting muchina

·Abrasives

·Blast nozzle

Muchina wejetblasting unoshandisa mhepo yakamanikidzwa sesimba rekugadzira matanda ejeti akakwira-kumhanya kupfapfaidza zvinhu (pfuti inoputika girazi mabhero, dema corundum, chena corundum, alumina, jecha requartz, emery, jecha resimbi, ore yemhangura, jecha regungwa) yakapfapfaidzwa pamusoro. yebasa rekushanda rinofanira kugadziriswa nekukurumidza, iyo inoshandura maitiro emagetsi ekunze kwekunze kwebasa rekushanda. Pamusana pekugadzirisa uye kucheka chiito cheabrasive pamusoro pebasa rekushanda, pamusoro pebasa rekushanda rinowana humwe hutsanana uye hukasha hwakasiyana. Iyo mechanical properties yepamusoro pebasa rekushanda inovandudzwa.

Pasinei nezita racho, jecha handiro chete zvinhu zvinogona kushandiswa mu "sandblasting" maitiro. Mabrasives akasiyana anogona kushandiswa zvichienderana nezvaari kushandiswa pazviri. Aya abrasives anogona kusanganisira:

·Steel grit

·Marasha slag

·Dry ice

·Walnut uye kokonati mateko

·Girazi rakapwanyika

Magiya ekuchengetedza akakodzera anofanirwa kushandiswa panguva yekuputika kwejecha. Iyo abrasive particles inogona kutsamwisa maziso neganda, uye kana inhaled, inogona kukonzera silicosis. Chero ani ari kuita sandblasting anofanirwa kugara akapfeka zvakaringana zvekuchengetedza.

Kunze kwezvo, blast nozzle zvakare chinhu chakakosha. Iko kune kunyanya marudzi maviri ekuputika nozzles: yakarurama bore uyeventure type. Pakusarudza bhomba nozzle, unogona kutarisa kune yedu chimwe chinyorwa che"Matanho mana anokuudza nzira yekusarudza yakakodzera kuputika nozzles".
