Ingabe I-Dustless Blasting Ayinaluthuli Ngempela?

Njengendlela entsha nethuthukisiwe yokuqhuma kwe-abrasive, ukuqhuma okungenathuli kuthola ukunakwa okuphezulu. Kubhekwa njengendlela evamile yokulungiswa kwendawo yendlela yokuhlanza ephumelelayo nemvelo.

Kunezinzuzo eziningi zokuqhumisa okungenathuli, okunye okucatshangwayo ukuthi akukhiqizi uthuli. Nokho, tlapha ayikho into ebizwa ngokuthi "okungenathuli" noma "okungenayo uthuli" embonini yokulungisa indawo. Zonke izinto eziqhumayo eziqhumayo ezisebenza ngaphansi kwezimo ezijwayelekile zikhiqiza uthuli.

Ngakho-ke, mhlawumbe uyazibuza ukuthi kungani kubizwa ngokuthi i-dustless blasting uma kungelona uthuli oluyiziro?

Kwenzeka kanjani uthuli?

Uma inhlayiya yemidiya ehubhukayo iphahlazeka, ihlukana ibe yizinhlayiyana ezincane. Izinhlayiya ezincane kunazo zonke ziyehluleka ukuwela phansi ngenxa yokuntuleka kwesisindo lapho kukhona isiphithiphithi somoya esikhiqizwa ngesikhathi sokuqhuma okubi.

Ngokuqhuma okumanzi, i-abrasive ihlanganiswengasemanzini. Lapho izinhlayiya ziphahlazeka phezu komthelela, izinhlayiya ezincane ezimanzi ezilandelayo zibaabanjiwengamanzi namandla adonsela phansi kuwadonsela phansi, naphezu kokunyakaza komoya.

Kodwa-ke, ezinye izinhlayiya ezincane zincane kakhulu, kangangokuthi nakuba zimbozwe emanzini azithathi isisindo esanele ukuze zimelane namandla okuqhuma komoya, futhi ziyasuswa.emoyeniemkhathini. Ngaphezu kwalokho, akuzona zonke izinhlayiya ezincane ezifakwe emanzini. Izinhlayiya ezincane eziphuma phakathi nendawo eyomile yezinhlayiyana zangempela zingase zingamanziswa nhlobo. Yingakho kungekho ukuqhumisa okusekelwe emanzini okungaqeda ngokuphelele uthuli.

Yini okufanele siyibheke?

Ukuqhuma okunamanzi okulimazayo kusebenzisa amanzi ukuze kuthwebule izinhlayiya ngaphambi kokuba zingene emoyeni, kodwa ngeke zikwazi ukuzibamba zonke. Kodwa-ke, lokho elikuthwebulayo kwenza inqubo ibe eyodwa ama-blasters amaningi ayikhethayo kunezindlela zendabuko.

Iziqhumane eziqhumayo zisebenzisa isivikelo sokuphefumula ukuze zikhiphe uthuli, izinsimbi ezisindayo, nezinye izinto eziyingozi emaphashini azo. Okukhathaza kakhulu uthuli lwe-silica, olubangela i-silicosis.I-Silicosis ibangelwa ukuphefumula kwezinhlayiya ezingabonakali (i-silica) ezidalwa yi-sandblasting. I-silica iyingxenye yamaminerali yesihlabathi, idwala, namanye ama-mineral ores. Lezi zinhlayiya zilimaza amaphaphu akho ngokuhamba kwesikhathi okungase kube lukhuni ikhono lakho lokuphefumula.

I-blaster esebenza ngaphansi kombono oyiphutha wokuthi inqubo yakhe ayikhiqizi uthuli ingase icabange ngokuphusile ukuthi ukuvikela ukuphefumula akudingekile.

Ukuqonda ukuthi ukuqhunyiswa okumanzi kusakhiqiza lezi zinhlayiya eziyingozi kubalulekile empilweni yakho.

Yiziphi izinzuzo zokuqhunyiswa okumanzi?

Uma kuthathwa izinyathelo ezifanele, izinzuzo zokuqhunyiswa kwe-abrasive ezimanzi ziningi. Okokuqala, ukuvikela kwakho kulula kakhulu futhi kulula. I-blast suit okumele igqokwe uma kuqhunyiswa i-abrasive emanzi ihlanganisa ukuvikela amehlo, ukuvikela ukuzwa, kanye nomshini wokuphefumula.

Ngakolunye uhlangothi, amasudi okuqhuma okomile ahlanganisa isudi eqhumayo, amagilavu, umakalabha/ihood, nokuvikela ukuzwa.

Enye inzuzo ukuthi ukusethwa kwesiqukathi sokuqhunyiswa kwe-abrasive okumanzi kuncane kunokuqhuma okuvamile. Esikhundleni sokuqinisekisa ukuthi indawo eyomile eqhumayo iqukethe ngokugcwele, i-tarp elula esethelwe ukuhlanzwa kalula yikho kuphela oyokudinga.

Lolu hlobo lokuqhuma lusebenzisa imidiya embalwa kunokuqhuma okomile kanye nenani eliphansi kakhulu lamanzi uma kuqhathaniswa nokuqhunyiswa kwe-slurry, okukongela imali ngokuhamba kwesikhathi.

Ngokuqhunyiswa kwe-abrasive okumanzi, amanzi asiza futhi ukugcina indawo eyinsimbi ipholile uma kuqhunyiswa. Lokhu kubaluleke kakhulu lapho kuqhunyiswa izinsimbi ezincane.

Ingabe kufanele sibheke ekuqhumeni kwe-abrasive okumanzi?

Ukuqhumisa okumanzi kungasetshenziswa ezinhlelweni eziningi ezihlukahlukene: kusukela ekubuyiselweni kwakudala kuya ekulungiseni kwendawo. Iphinde idale izindleko eziphansi zokusebenza kanye nokuguga kwemishini uma kuqhathaniswa nezinye izinhlobo zokuqhumisa.

Nakuba ingeke ikwazi ukuqeda uthuli, kuseyisinqumo esihle uma ufuna indawo engcono yokuqhumisa ukuqhuma futhi ukhetha indlela ehlolwe isikhathi.
