Izinhlobo Zokuqhunyiswa Kwe-Abrasive

Namuhla, ukuqhunyiswa kwe-abrasive kusetshenziswa kabanzi ezimbonini eziningi. Okufana nokwakhiwa kwemikhumbi nokuhlanza izindonga zemikhumbi, ukulungisa nokubuyisela izimoto, ukuqedela insimbi, ukushisela, ukulungiswa kwendawo, nokunamathiswa okungaphezulu noma okusampushana njll. Ukuqhunyiswa kwe-abrasive kwaziwa kakhulu njengendlela abantu abayisebenzisayo ukuhlanza noma ukulungisa indawo. Ukuqhuma kwe-abrasive kungaphinda kubizwe ngokuthi ukuqhunyiswa kwesihlabathi, ukuqhuma kwegrit, kanye nokuqhuma kwemidiya. Sizichaza kanjani ukuthi yiziphi izinhlobo zokuqhumisa ezisuselwe ezintweni ezibrasi ezizisebenzisayo.

Izinhlobo Zokuqhunyiswa Kwe-Abrasive

1. Ukuqhunyiswa kwesihlabathi

I-sandblasting ingenye yezindlela ezidume kakhulu zokuqhumisa abantu abathanda ukuyisebenzisela ukuhlanza indawo. I-abrasive material yizinhlayiya zesihlabathi se-silica. Izinhlayiya ze-silica zibukhali, futhi zingakwazi ukushelela phezulu ngesivinini esikhulu. Ngakho-ke, abantu ngokuvamile bakhetha i-sandblasting yokukhipha ukugqwala ensimbi.

Into embi nge-silica ukuthi ingabangela i-silicaosis okuyisifo esiyingozi samaphaphu esibangelwa ukuphefumula uthuli oluqukethe isilica. Cabanga ngempilo ye-blasters, i-sandblasting iye yaphela kancane kancane ukusetshenziswa.

2. Ukuqhunyiswa Okumanzi

Ukuqhuma okumanzi kusebenzisa amanzi njengama-abrasives. Uma kuqhathaniswa nokuqhunyiswa kwesihlabathi, ukuqhumisa okumanzi kuyindlela yokuqhuma evumelana nemvelo. Iqhuma ngaphandle kokudala uthuli okwenza ibe inzuzo enkulu yokuqhuma okumanzi. Ukwengeza, ukungeza amanzi okuqhuma kuyenza ibe bushelelezi futhi igcine ilingana.

3. Soda Blasting

Ukuqhunyiswa kwesoda kusebenzisa i-sodium bicarbonate njengesisetshenziswa esibi. Uma uqhathanisa neminye imidiya ehubhukayo, ubulukhuni be-sodium bicarbonate buphansi kakhulu okusho ukuthi ingasetshenziselwa ukuhlanza indawo ngaphandle kokulimala okungaphezulu. Izicelo zokuqhunyiswa kwesoda zifaka phakathi ukususwa kopende, ukususwa kwegraffiti, ukubuyiselwa komlando, nokususwa kwezinsini, njll. Ngaphezu kwalokho, ukuqhunyiswa kwesoda nakho kuyahambisana nemvelo. Into kuphela ukuthi i-soda bicarbonate ingabangela umonakalo otshanini nezinye izitshalo.

4. Vacuum Blasting

Ukuqhuma kwevacuum nakho kungabizwa njengokuqhumisa okungenathuli ngoba kukhiqiza uthuli nokuchitheka okuncane kakhulu. Ngenkathi i-vacuum blasting, izinhlayiya ezi-abrasive kanye nezinto ezivela ku-substrate ziqoqwa nge-vacuum ngesikhathi esifanayo. Ngakho-ke, ukuqhunyiswa kwe-vacuum kunganciphisa kakhulu ukungcoliswa kwemvelo okuvela ezinhlayiyeni eziqhumayo. Ingavikela futhi impilo yomsebenzisi ezinhlayiyeni ezinuka umoya.

5. Steel Grit Blasting

I-steel grit nayo iyisiqhumane esivame kakhulu. Ngokungafani nokudubula kwensimbi, insalela yensimbi yakheka ngokungahleliwe, futhi ibukhali kakhulu. Ngakho-ke, ukuqhunyiswa kwegrit yensimbi kuvame ukusetshenziswa ezindaweni eziqinile.

Ngaphandle kokuqhunyiswa kwesihlabathi, ukuqhunyiswa okumanzi, ukuqhunyiswa kwesoda, ukuqhunyiswa kwe-vacuum, nokuqhunyiswa kwensimbi, kusenezinhlobo eziningi ezahlukene zokuqhuma njenge-slag yamalahle, izikhwebu zombila, nokunye. Abantu bakhetha imidiya elimazayo ngokusekelwe ezidingweni zabo zenani, ubulukhuni, futhi uma befuna ukulimaza okungaphezulu. Kunezinto eziningi okudingeka zicatshangelwe ngenkathi kukhethwa imidiya elimazayo.

Abantu futhi badinga ukukhetha izinto zokwakha imibhobho namalayini we-nozzle ngokusekelwe kumidiya ehubhukayo abayikhethayo. Kwa-BSTEC, noma ngabe usebenzisa yiphi imidiya ehubhukayo, sinazo zonke izinhlobo zemibhobho namalayini we-nozzle. I-silicon carbide, i-tungsten carbide, ne-boron carbide konke kuyatholakala. Vele usitshele ukuthi yini oyidingayo noma iyiphi imidiya elumayo oyisebenzisayo, sizokutholela umbhobho ofaneleka kakhulu.
