Uyazi i-sandblasting? –Ukwethulwa okufushane kwe-sandblasting 

I-Sandblasting eyaziwa nangokuthi i-abrasive blasting, isenzo sokuqhubeza izinhlayiya ezicolisekileyo zezinto eziqhumayo ngesivinini esikhulu ukuya endaweni ukuze ziyihlanze noma ziyicime. Kuyinqubo yokuqeda indawo engaphezulu ebandakanya ukusetshenziswa komshini onamandla (i-air compressor) kanye nomshini we-sandblasting  ukufafaza izinhlayiya ezilimazayo ngaphansi kwengcindezi ephezulu endaweni. Kubizwa ngokuthi "i-sandblasting" ngoba iqhumisa phezulu ngezinhlayiya zesihlabathi. Lapho izinhlayiya zesihlabathi zishaya phezulu, zakha ukuthungwa okushelelayo nokulingana.

Ukusetshenziswa Sandblasting

I-sandblasting ingenye yezindlela ezisebenza kahle kakhulu zokuhlanza nokulungisa izindawo. Abasebenza ngokhuni, ochwepheshe bemishini, oomakhenikha bezimoto, nokunye bangasebenzisa ukuqhunyiswa kwesihlabathi emsebenzini wabo, ikakhulukazi uma beqonda ngokugcwele izindlela eziningi zokusebenzisa ukuqhunyiswa kwesihlabathi.

1. Susa Ukugqwala Nokugqwala:Ukusetshenziswa okuvame kakhulu kwemidiya nokuqhunyiswa kwesihlabathi ukususa ukugqwala nokugqwala. Ama-sandblasters angasetshenziswa ukususa upende, ukugqwala, nokunye ukungcola okungaphezulu ezimotweni, ezindlini, emishinini, nakunoma iyiphi enye indawo.

2. UbusoUkwelashwa kwangaphambili:Ukuqhunyiswa kwesihlabathi nokuqhunyiswa kwemidiya kuyindlela enhle yokwenza indawo engaphezulu ilungele upende noma ukunameka. Emhlabeni wezimoto kuyindlela ethandwayo yokuqhuma kwe-chassis ngaphambilii-powder enamathelayona. Imidiya enolaka kakhulu njenge-aluminium oxide ishiya iphrofayili endaweni esiza ngempela ijazi lempushana linamathela kangcono. Yingakho iningi lama-powder coater likhetha izinto ukuthi ziqhunyiswe yimidiya ngaphambi kokumbozwa.

3. Ukulungiswa kwezingxenye ezindala:ukulungiswa nokuhlanza zonke izingxenye ezihambayo ezifana nezimoto, izithuthuthu, izinto zokusebenza ze-electromechanical, njll., ozakwethu baqeda ukucindezeleka kokukhathala futhi bandise impilo yesevisi.

4. Dala Ukwakheka Ngokwezifiso Nomsebenzi Wobuciko: Kwezinye izingcezu zomsebenzi ezinenhloso ekhethekile, i-sandblasting ingafinyelela ukubonakaliswa okuhlukile noma i-matt. Okufana nokupholishwa kwezingcezu zensimbi engagqwali namapulasitiki, ukupholishwa kwe-jade, ukuhlanganisa indawo engaphezulu yefenisha yokhuni, iphethini ebusweni bengilazi eyisithwathwa, kanye nokuthumela umbhalo ebusweni bendwangu, njll. 

5. Ukulingisa okushelelayo nemiphetho:Kwesinye isikhathi ukuqhunyiswa kwemidiya kungashelela noma kupholise kancane indawo emaholoholo. Uma unokulingisa okungalungile okunamachopho acijile noma angajwayelekile ungasebenzisa i-media blaster enengilazi echotshoziwe ukuze usheleleze indawo noma uthambise umphetho obukhali.

Ukuqhunyiswa Kwesanti Kwenziwa Kanjani

Ukusethwa kwe-sandblasting ngokuvamile kuhlanganisa izingxenye ezintathu ezibalulekile:

·Umshini wokuqhumisa isihlabathi

·Ama-Abrasives

·Ukuqhuma kwe-nozzle

Umshini we-sandblasting usebenzisa umoya ocindezelwe njengamandla okwenza imishayo yejethi enesivinini esikhulu ukufafaza izinto (ubuhlalu bengilazi eqhumayo, i-corundum emnyama, i-corundum emhlophe, i-alumina, isihlabathi se-quartz, i-emery, isihlabathi sensimbi, insimbi yethusi, isihlabathi solwandle) sifafazwe phezulu. wocezu lomsebenzi okufanele lucutshungulwe ngesivinini esikhulu, okushintsha izakhiwo zemishini yendawo yangaphandle yendawo yokusebenza. Ngenxa yomthelela kanye nesenzo sokusika se-abrasive ebusweni bomsebenzi womsebenzi, ingaphezulu lesiqephu somsebenzi lithola izinga elithile lokuhlanzeka kanye nobulukhuni obuhlukile. Izakhiwo zemishini ebusweni bomsebenzi womsebenzi ziyathuthukiswa.

Naphezu kwegama, isihlabathi akuyona ukuphela kwento engasetshenziswa enqubweni "yokuqhumisa isihlabathi". Ama-abrasive ahlukene angasetshenziswa kuye ngento asetshenziswa kuyo. Lawa ma-abrasives angafaka:

·Insimbi yensimbi

·I-slag yamalahle

·Iqhwa elomile

·Amagobolondo kakhukhunathi nama-walnut

·Ingilazi echotshoziwe

Imishini yokuphepha efanele kufanele isetshenziswe ngesikhathi sokuqhunyiswa kwesihlabathi. Izinhlayiya ezilumayo zingacasula amehlo nesikhumba, futhi uma zihogela, zingabangela i-silicosis. Noma ubani owenza i-sandblasting kufanele ngaso sonke isikhathi agqoke izinto ezifanele zokuphepha.

Ngaphandle kwalokho, i-blast nozzle nayo iyingxenye ebalulekile. Kunezinhlobo ezimbili eziyinhloko zama-nozzles aqhumayo: i-straight bore kanyeumsebenzi uhlobo. Ukukhetha umbhobho oqhumayo, ungabheka enye indatshana yethu ethi"Izinyathelo ezine zikutshela ukuthi ungakhetha kanjani imibhobho yokuqhuma efanele".
