Ngaba Ngokwenene Ukuqhushumba Okungenaluthuli Akunaluthuli?

Njengendlela entsha nephuculweyo yokuqhushumba kweabrasive, uqhushumbo olungenathuli lufumana ingqwalasela ephezulu. Kuthathwa njengeyona nto iphambili yokulungiswa komphezulu wendlela yokucoca esebenzayo kunye nokusingqongileyo.

Zininzi izibonelelo zokuqhushumba okungenathuli, enye yezona zinto zicingwayo kukuba ayivelisi uthuli. Nangona kunjalo, tApha akukho nto ifana "nothuli" okanye "olungenathuli" kushishino lokulungiselela umphezulu. Zonke izixhobo eziqhumayo ezisebenza phantsi kweemeko eziqhelekileyo zivelisa uthuli.

Ke, mhlawumbi uyazibuza ukuba kutheni ibizwa ngokuba kukuqhushumba okungenathuli ukuba ayilulo uthuli lweziro?

Kwenzeka njani uthuli?

Xa i-particle of abrasive media chatters, ihlahlela ibe ngamancinci amancinci. Awona mancinci amasuntswana amancinane ayasilela emhlabeni ngenxa yokungabikho kobunzima kubukho besiphithiphithi somoya esiveliswe ngexesha lokuqhushumba kweabrasive.

Ngokuqhushumba okumanzi, i-abrasive ifakwengasemanzini. Xa iqhekezana liqhekeka phezu kwempembelelo, amasuntswana angaphantsi amanzi alandelayoebanjiwengamanzi kunye nomxhuzulane ubatsalela emgangathweni, nangona kukho isiphithiphithi somoya.

Nangona kunjalo, amanye amasuntswana amancinci, kangangokuba nangona efakwe emanzini awathathi ubunzima obaneleyo ukuchasana namandla esiphithiphithi somoya, kwaye ayenziwa.emoyeniemoyeni. Ngaphezu koko, ayizizo zonke iincinci ezincinci ezifakwe emanzini. Amasuntswana amancinci aphuma kumbindi owomileyo wesuntswana lokuqala asenokungafumisi kwaphela. Yiyo loo nto kungabikho ukuqhushumba okusekwe kumanzi kunokuphelisa ngokupheleleyo uthuli.

Yintoni esifanele sijonge kuyo?

Uqhushumbo olumanzi lusebenzisa amanzi ukubamba amasuntswana ngaphambi kokuba angene emoyeni, kodwa awanakukwazi ukuwabamba onke. Nangona kunjalo, into eyibambayo yenza ukuba inkqubo ibe yeyona nto ithandwa kakhulu yi-blasters kuneendlela zemveli.

Iziqhushumbisi eziqhumayo zisebenzisa ukhuseleko lokuphefumla ukugcina uthuli, isinyithi esinzima, kunye nezinye izinto eziyingozi eziphuma emiphungeni yazo. Eyona nto ixhalabisayo luthuli lwe-silica, olubangela i-silicosis.I-Silicosis ibangelwa ukuphefumla kwiincinci ezingabonakaliyo (silica) ezenziwe ngokuqhunyiswa kwesanti. I-silica yinxalenye yeminerali yesanti, ilitye, kunye nezinye i-mineral ores. La masuntswana ayonzakalisa imiphunga ngokuhamba kwexesha nto leyo enokwenza lukhuni ukukwazi kwakho ukuphefumla.

I-blaster esebenza phantsi kwengcamango ephosakeleyo yokuba inkqubo yakhe ayivelisi uthuli inokucinga ukuba ukhuseleko lokuphefumla aluyomfuneko.

Ukuqonda ukuba ukuqhushumba okumanzi kusavelisa la masuntswana ayingozi kubalulekile kwimpilo yakho.

Zeziphi iingenelo zokuqhushumba okumanzi?

Xa kuthatyathwa amanyathelo okhuseleko afanelekileyo, izibonelelo zokuqhushumba kwe-abrasive emanzi zininzi. Okokuqala, ukhuseleko lwakho lukhululekile kwaye lukhaphukhaphu. Isuti yokuqhushumba ekufuneka inxitywe xa kuqhunyiswa iabrasive emanzi ibandakanya ukhuseleko lwamehlo, ukhuselo lokuva, kunye nesixhobo sokuphefumla.

Ngakolunye uhlangothi, iisuti eziqhumayo ezomileyo ziquka i-suit blast, iiglavu, i-helmet / i-hood, kunye nokukhusela ukuva.

Olunye uncedo kukuba ukuseta isiqulatho sokuqhushumba kweabrasive emanzi kuncinci kunokudubula kwesintu. Endaweni yokuqinisekisa ukuba indawo eyomileyo eqhumayo iqulethwe ngokupheleleyo, i-tarp elula esetelwe ukucoca lula yiyo yonke into oya kuyidinga.

Olu hlobo lokuqhushumba lukwasebenzisa imithombo yeendaba embalwa kunokudubula okomileyo kunye nesixa esisezantsi kakhulu samanzi xa kuthelekiswa nokuqhushumba kodaka, okonga imali ekuhambeni kwexesha.

Ngokuqhushumba kweabrasive emanzi, amanzi akwanceda ukugcina imiphezulu yesinyithi ipholile xa kuqhushumba. Oku kubaluleke ngakumbi xa kuqhunyiswa iintsimbi ezibhityileyo.

Ngaba kufuneka sijonge kwi-abrasive blasting emanzi?

Ukudubula okumanzi kunokusetyenziswa kwiindidi ezahlukeneyo zezicelo: ukusuka kwi-antique restoration ukuya kwi-prep surface. Ikwadala iindleko zokusebenza ezincinci kunye nokunxiba kwezixhobo xa kuthelekiswa nezinye iindlela zokuqhushumba.

Nangona ingenako ukuphelisa ngokupheleleyo uthuli, iselukhetho olulungileyo ukuba ufuna indawo engcono yokuqhushumba kwaye ukhetha indlela evavanyiweyo ixesha.
