Iyiphi indondo ecwebezelayo futhi ebukeka isezingeni eliphezulu?

Yini iindondolokho kuyacwebezela futhi kubukeka kusezingeni eliphezulu kakhulu?

Izinsimbi zisondelene nomoya unyaka wonke, futhi izinqubo zivame ukungezwa ebusweni bezindondo, izindondo, izindondo zesikhumbuzo, njll. ukuze zinikeze ukuvikeleka okuthile kwemikhiqizo yensimbi.
Okulandelayo izindondo zama-Olympics Wasebusika zango-2022, eziqhunyiswe phezulu. Namuhla, ake sethule izindlela ezivamile zokuqhumisa isihlabathi.

I-Sandblasting iyinqubo yokwelapha ngaphezulu kwezingcezu zokusebenza. Kusetshenziswa umoya ocindezelwe njengamandla, kwakheka ugongolo lwejethi olunesivinini esikhulu ukuze lufafaze izinto (itshe lensimbi yethusi, isihlabathi se-quartz, isihlabathi sedayimane, isihlabathi sensimbi, isihlabathi solwandle) ngesivinini esikhulu phezu kwendawo yokusebenza okufanele iphathwe, okubangela izinguquko ukubukeka noma ukuma kwendawo yokusebenza. Ngenxa yomthelela kanye nemiphumela yokusika yama-abrasives ebusweni bomsebenzi, ingaphezulu le-workpiece lithola izinga elithile lokuhlanzeka kanye nobunzima obuhlukile, okuthuthukisa izakhiwo zemishini ye-workpiece surface. Ngakho-ke, ukumelana nokukhathala kwe-workpiece kuyathuthukiswa, ukunamathela phakathi kwayo kanye ne-coating kuyanda, ukuqina kwe-coating kunwetshiwe, futhi kubuye kuhambisane nokulinganisa nokuhlobisa kwe-coating.

Izinto zokusetshenziswa zokwelashwa kwe-sandblasting

I-Sandblasting: Itemu lobuchwepheshe elisetshenziswa ekubunjweni kwezinhlamvu zemali zegolide nezesiliva. Ekukhiqizeni isikhunta sezinhlamvu zemali zegolide nezesiliva, osayizi abahlukahlukene kanye namamodeli ezinhlayiya zesihlabathi sensimbi zisetshenziselwa ukufafaza ingxenye yephethini endaweni enesithwathwa esihle kakhulu. Lapho kukhiqizwa izinhlamvu zemali zegolide nezesiliva, ukuthungwa okuhle kubonakala engxenyeni yephethini, okwandisa umuzwa wobukhulu nokwendlaleka. I-Sandblasting: (kubhekiselwa ekukhishweni kokugqwala ezindaweni zensimbi noma ukucwenga endaweni yensimbi) ihlukaniswe yaba isihlabathi se-quartz esivamile nesihlabathi se-quartz esicwengisisiwe: esinokuqina okuphezulu kanye nomphumela omuhle wokukhipha ukugqwala.

Inqubo ye-Sandblasting

Isiteji sangaphambi kokucubungula

Isigaba sokwelashwa sangaphambi kwenqubo sibhekisela ekwelashweni okufanele kwenziwe ebusweni bomsebenzi ngaphambi kokufuthwa noma ukumbozwa ngesendlalelo sokuzivikela. Izinga lokwelashwa kwangaphambili kubuchwepheshe be-sandblasting lithinta ukunamathela, ukubukeka, ukumelana nomswakama, nokumelana nokugqwala kwezingubo. Uma umsebenzi wangaphambi kokwelashwa ungenziwanga kahle, ukugqwala kuzoqhubeka kusakazeka ngaphansi kokugqoka, okwenza ukuba ukugqoka kukhishwe izicucu. Ngemuva kokuhlanza ngokucophelela indawo kanye nokuhlanza okulula okujwayelekile kwendawo yokusebenza, impilo yokugqoka ingaqhathaniswa nezikhathi ezingu-4-5 usebenzisa indlela yokubeka ilanga. Ziningi izindlela zokuhlanza ingaphezulu, kodwa ezivame ukwamukelwa ukuhlanzwa kwezinyibilikisi, ukuwasha nge-asidi, amathuluzi okwenziwa ngesandla, namathuluzi okwenziwa ngesandla.

Isigaba senqubo

Inqubo ye-sandblasting isebenzisa umoya ocindezelwe njengamandla okwenza i-jet beam enesivinini esikhulu, efafaza izinto kanye nezinye izinto phezu kwendawo yokusebenza ukuze iphathwe ngesivinini esikhulu, okubangela izinguquko ebusweni bomsebenzi. Ngenxa yomthelela kanye nemiphumela yokusika yama-abrasives endaweni yokusebenza, indawo yokusebenza ithola izinga elithile lokuhlanzeka kanye nobulukhuni obuhlukile, ukuthuthukisa izakhiwo zemishini yendawo yokusebenza.

Izinzuzo zobuchwepheshe be-sandblasting

(1) Ukumboza nokuhlanganisa i-sandblasting yangaphambi kokwelashwa kungasusa konke ukungcola okufana nokugqwala endaweni yokusebenza, futhi kusungule iphethini eyisisekelo ebaluleke kakhulu (evame ukwaziwa njengendawo emagebhugebhu) ngaphezulu. Ingase futhi ifinyelele amazinga ahlukene okumahhadla ngokushintshanisa ama-abrasive anosayizi bezinhlayiyana ezihlukene, njengamathuluzi endizayo abrasive, athuthukise kakhulu amandla okubopha ama-coatings nama-coatings. Noma yenza ukubopha kwezingxenye zokunamathisela kuqine futhi kube nekhwalithi engcono.
（2） Ingaphezulu elimaholoholo lokulingisa kanye nokuhlanza nokupholishwa ngemva kokwelashwa kokushisa kungahlanzwa nge-sandblasting, engasusa konke ukungcola (okufana nesikhumba se-oxide, amabala kawoyela, njll.) endaweni yokusebenza efojiwe futhi ephethwe ukushisa. Ukucwebezeliswa kwendawo kungathuthukisa ukushelela kwengcezu yokusebenza, kuveza umfaniswano nombala wensimbi ongaguquki, okwenza ukubukeka kubonakale kukuhle kakhulu futhi kukhange.
(3) Ukuhlanzwa kwe-Burr nokuhlobisa indawo ye-sandblasting kungahlanza ama-burrs amancane ebusweni bezinto zokusebenza, kwenze ingaphezulu lezinto zokusebenza zibe bushelelezi, kususe ukulimala kwama-burrs, futhi kuthuthukise ibanga. Futhi i-sandblasting ingakha amakhona ayindilinga amancane kakhulu kusixhumi esibonakalayo sendawo yokusebenza, iyenze ibe yinhle futhi inembe kakhudlwana.
(4) Ngemva kokuqhunyiswa kwesihlabathi, izindawo ezifanayo nezinhle ze-convex zingakhiqizwa phezulu, okuvumela uwoyela wokugcoba ukuba ugcinwe, ngaleyo ndlela kuthuthukiswe izimo zokuthambisa nokunciphisa umsindo ukuze kwandiswe impilo yesevisi.
(5) Ngezinhloso ezithile ezikhethekile zokusebenza, i-sandblasting ingafinyelela ukuboniswa okuhlukile noma imiphumela ye-matte ngokuthanda kwakho. Okufana nokupholisha izinto zokusebenza zensimbi engagqwali namapulastiki, ukupholisha izinto ze-jade, ukwelapha okungaphezulu kwe-matte kwefenisha yokhuni, amaphethini ephethini endaweni yengilazi eyisithwathwa, kanye nokwenza kahle kwendwangu.

Sekukonke, kwenza indondo yegolide ibonakale ithuthuke kakhulu, iqinile futhi ihlala isikhathi eside
