Zvinhu zvakakosha zveSandblasting

——Master blasting yejecha kubva pazvinhu zvishanu

Sandblasting inzira yekurapa pamusoro nekufambisa twumabrasive particles at high velocity kwariri. Iyo iri nyore uye yakakwirira-inoshanda nzira yekugadzira inodiwa pamusoro roughness.Nekudaro, vanhu vazhinji vanogona kusaziva nzira yekuwana yakanakisa kuputika. Panyaya iyi, ngatidzidzei zvakawanda pamusoro pezvinhu zvakakosha zvejecha.

Chinhu chekutanga: Mhepo yakadzvanywa

Sandblasting process inowanzo sanganisira zvikamu zvitatu zvikuru, zvinova mhepo compressor, abrasive particle, uye nozzle. Mhepo yakadzvanywa, sedanho rekutanga, yakakosha pakufambisa mabrasives.Hunhu hwayo hunonyanya kutariswa nemativi maviri: mhepo yekumanikidza uye mhando yemhepo. Yakasiyana pamusoro roughness chinodiwa inoda kwakakodzera air pressure. Nzvimbo yakaoma kuchenesa inoda kudzvanywa kwepamusoro, nepo yakapfava ichida kuderera kuderedza kuita kwesimba.Hunhu hwemhepo (air quality) zvinoreva hutsanana hwemhepo hunokwanisa kuyerwa ne cleaningmudziyo wekuona wemhepo yakamanikidzwa. Uyezve, kune zvakare midziyo yekuomesa yekubvisa hunyoro mumhepo.

Chinhu 2: Abrasives 

Abrasive blasting ine akawanda maapplication, chimwe nechimwe chinoda kushandiswa kwemhando dzakasiyana dzeabrasive particles, anozivikanwa se blasting media.Common abrasives inotsanangurwa pasi apa.

Aluminium oxide: Aluminium oxide inoratidzira kuoma kwayo kwakanyanya uye simba. Iyo yeangular inogara kwenguva refu midhiya yekukurumidza etching inotungamira kune anchor pateni yepamusoro peprofile.

Glass Beads：Iro raundi soda-lime girazi. Kuenzaniswa nezvimwe zvinhu, girazi harina hukasha sekuputika midhiya sesimbi kupfura kana silicon carbide. Mabrasives egirazi mabhedhi ane kushushikana kushoma pamusoro pepamusoro kuti abudise inopenya uye satin matte mhando yekupedzisa.

Plastiki: Iri nyoro abrasive iyozvakakodzera ye mold kana zvikamu zvepurasitiki zvekuchenesa.

Silicon Carbide: Ndiyo yakaomesesa abrasive material inowanikwa inokodzera mushe mukuchenesa nzvimbo yakaoma zvikuru.

Steel Shot & Grit: Iabrasive inoshanda zvakanyanya nekuda kwekukasharara kwayo uye yakakwirira kudzokorodza zvakare.

Walnut Shells: Icho chinhu chechisikigo chine kuoma kwakagadzirwa kubva kune yakapwanyika makungu ewalnut, iyo yakaoma kune yakapfava abrasives.

Chinhu 3: Nozzle

Nozzle inoita basa rakakosha sechikamu chekupedzisira mukuputika, icho chinonyanya kukanganisa mhedzisiro yekupedzisa kwepamusoro.Zvinoenderana neakasiyana ekushandisa mamiriro uye pamusoro pekurapa zvinodiwa, isu tinofanirwa kusarudza yakanyanya kukodzerasandblastingmuromo, othewise,mhedzisiro yacho ichaderedzwa zvakanyanya.

Saizi

Mumwe nomumwemhando yenozzle ine saizi yakasiyanas. Sarudza muromo une diki diki yebore uye uchadarokutambisa kumanikidza, nepo kana iri too mukuru,uchashaya pressure yekuputika zvine pundutso.

The Material

Zvinhu zvitatu zvakakurumbira zvinoshandiswa nhasi pakuputika nozzle ndeye boron carbide, silicon carbide, uyetungsten carbide. Boron carbide nozzles inoratidzira zvakanyanya kuomarara, kureruka, uye yakanakisa abrasion kuramba. Silicon carbide nozzles yakafanana neboron carbide. Iine kushanda kwakaderera mukudzivisa kupfeka.Tungsten carbide nozzles yakaoma uye ine yakagadzikana chimiro chinodiwa kushoma kuchengetedzwa, nepo ichirema.

The Type

Venturi Nozzle: Yakagadzirwa basd pa musimboti weVenturi Eeffect ndiko kudzikiswa kwekumanikidzwa kwemvura inoenda kukuwedzera kwemvura’s velocity. Naizvozvo, itsblast pattern structure inoita kuti ive yepamusoro-soro mukuputika.

Yakananga Bore Nozzle:Inogadzira yakasimba kuputika pateni iyo isinoshandiswa panodiwa zvidimbu zvidiki kana kuputika kwechiedza.

Mvura Induction Nozzle: Imhando yemhuno zvese zviripo mukupusha kwakaoma uye kuputika kwemvura. Kuenzaniswa nemamwe ma nozzles, ine hushamwari kune hutano hwekudzvinyirira guruva.

Yemukati Pipe Blast Nozzle: Ndizvokushandiswa kuchenesa mukati memadziro epombi inoputika mucone pateni yakashongedzerwa nemidziyo yakasiyana-siyana senge collar sets, centering carriage, nezvimwe.

Curved Nozzle: Iyo inoratidzira mune yakakomberedzwa kona yekubuda, iyo inosimudzira kuwana yejecha kuputika munzvimbo dzakaoma kana dzakasimba-yakakodzera.

Chinhu chechina: Surface Condition

Mamwe maumbirwo epamusoro akaoma uye anoda simba guru rekuita kuti richinje chimiro chepamusoro. Dzimwe nzvimbo dzakanyanya kutetereka,requiringkuderera zvishoma.

Chinhu chechishanu: Mwenje

Kune akasiyana mashandisirwo mamiriro ejecha. Inogona kunge iri mumba kana kunze. Kumwe kuputika kwejecha kuchaitwa mubhokisi rejecha. Muchiitiko ichi, mushandi anofanira kugadzirirayakanaka-mhandokuvheneka paunenge uchiita sandblasting kuita nanicherechedzamamiriro ejecha.

Sarudza kuumbwa kwezvinhu zvishanu izvi zvinoenderana nezvinodiwa nejecha, uye iwe uchawana yakanakira sandblasting maitiro.
