Umehluko Phakathi Kokuqhuma Kokudubula Nokuqhunyiswa Kwesihlabathi

Njengabantu abaningi, ungase udideke ngomehluko phakathi kokuqhunyiswa kwesihlabathi nokuqhunyiswa kwesibhamu. La magama womabili abonakala afana kodwa ukuqhunyiswa kwesihlabathi nokuqhunyiswa kwesibhamu kuyizinqubo ezihlukene.

I-Sandblasting inqubo yokuhambisa leyo midiya ehubhukayo kusetshenziswa umoya ocindezelwe ukuhlanza indawo engaphezulu. Le nqubo yokuhlanza nokulungisa ithatha umoya ocindezelwe njengomthombo wamandla futhi iqondise ukusakazwa komfutho ophezulu wemidiya ehubhukayo kungxenye ezoqhunyiswa. Lobo buso bungaba izingxenye ezishiselwe ezihlanzwa ngaphambi kokupenda, noma ingxenye ezenzakalelayo ihlanzwa kudoti, amafutha, namafutha nanoma yini edinga ukulungiswa kwendawo ngaphambi kokufaka upende nanoma yikuphi ukunamathela. Ngakho-ke enqubweni yokuqhuma kwesihlabathi, imidiya ye-sandblasting isheshiswa ngomoya ocindezelwe umoya (esikhundleni se-centrifugal turbine). Isihlabathi noma enye into elimazayo idlula epayipini elishayelwa umoya ocindezelwe, okuvumela umsebenzisi ukuthi alawule lapho kuqhunyiswa khona ukuqhuma, futhi ekugcineni iqhume ngombhobho engxenyeni.

I-shot blasting iwukusebenzisa i-impeller ejikelezayo enesivinini esikhulu ukuphonsa isibhamu esincane sensimbi noma isibhamu esincane sensimbi, bese ushaya ingxenye yengxenye ngesivinini esikhulu, ukuze kukhishwe ungqimba lwe-oxide ebusweni bengxenye. Ngesikhathi esifanayo, isibhamu sensimbi noma isibhamu sensimbi sishaya ubuso bengxenye ngesivinini esikhulu, okubangela ukuhlanekezela kwe-lattice ebusweni bengxenye ukwandisa ubulukhuni bobuso. Kuyindlela yokuhlanza ubuso bengxenye ukuqinisa okwangaphandle.

Esikhathini esidlule, ukuqhunyiswa kwesihlabathi kwakuyinqubo eyinhloko yokuqhumisa ekwelapheni ukudumba. Isihlabathi besitholakala kalula kunezinye imidiya. Kodwa isihlabathi sasinezinkinga ezifana nomswakama owakwenza kube nzima ukusabalalisa ngomoya ocindezelwe. Isihlabathi sasinokungcola okuningi okutholakala ezintweni zemvelo.

Inselele enkulu ekusebenziseni isihlabathi njengemidiya elimazayo izingozi zempilo yaso. Isihlabathi esisetshenziswa ekuqhunyisweni kwesihlabathi senziwa ngesilica. Uma izinhlayiya ze-silica zihogeliwe zihlala kusistimu yokuphefumula okungase kubangele izifo ezinzima zokuphefumula njenge-silica dust yaziwa njengomdlavuza wamaphaphu.

Umehluko phakathi kwe-sandblasting nokuqhunyiswa kwegrit noma okubizwa ngokuthi i-shot blasting kuncike endleleni yokufaka isicelo. Lapha, inqubo ye-sandblasting isebenzisa umoya ocindezelwe ukudubula imidiya elimazayo ngokwesibonelo isihlabathi ngokumelene nomkhiqizo oqhunyiswayo. I-shot blasting isebenzisa amandla aphakathi nendawo asuka emshinini ukuze kuqhunyiswe imidiya eqhumayo engxenyeni.

Ngokuvamile, ukuqhunyiswa kwesibhamu kusetshenziselwa izimo ezivamile, njll., futhi amakhanda aqhumayo amaningana ahlangene phezulu naphansi, kwesokunxele nakwesokudla, ngokusebenza kahle okuphezulu kanye nokungcoliswa okuncane.

Ngokuqhunyiswa kwesanti, isihlabathi siqhutshelwa phezulu. Ngokuqhunyiswa kwesibhamu, ngakolunye uhlangothi, amabhola ensimbi amancane noma ubuhlalu buqhutshwa phezu kwendawo. Amabhola noma ubuhlalu ngokuvamile benziwa ngensimbi engagqwali, ithusi, i-aluminium, noma i-zinc. Noma kunjalo, zonke lezi zinsimbi ziqinile kunesihlabathi, okwenza ukudubula kuqhume kahle kakhulu kunozakwabo we-sandblasting.

Ukufingqa, i-sandblasting iyashesha futhi iyonga. Ukuqhunyiswa kwesibhamu kuyinqubo yokwelapha ebandakanyeka kakhulu futhi kusebenzisa okokusebenza okuthuthuke kakhulu. Ngakho-ke, ukuqhunyiswa kwesibhamu kuhamba kancane futhi kuvame ukubiza kakhulu kunokuqhunyiswa kwesihlabathi. Kodwa-ke, kunemisebenzi engakwazi ukusingatha i-sandblasting. Khona-ke, inketho yakho kuphela ukuya ukuqhunyiswa kwesibhamu.
