Umahluko phakathi kokudutyulwa kokudutyulwa kunye nokudutyulwa kwesanti

Njengabantu abaninzi, unokubhideka malunga nomahluko phakathi kokuqhunyiswa kwesanti kunye nokudutyulwa kokudubula. La magama mabini abonakala efana kodwa ukuqhushumba kwesanti kunye nokudutyulwa ziinkqubo ezahlukileyo.

I-Sandblasting yinkqubo yokuqhubela phambili loo majelo e-abrasive usebenzisa umoya ocinezelweyo ukucoca umphezulu. Le nkqubo yokucoca kunye nokulungiselela ithatha umoya oxinzelelweyo njengomthombo wamandla kwaye iqondise umsinga woxinzelelo oluphezulu lwemithombo yeendaba e-abrasive ukuya kwindawo eya kuqhunyiswa. Lo mphezulu unokucocwa iindawo ezidityanisiweyo phambi kokupeyintwa, okanye inxalenye yeauto icocwe kukungcola, igrisi, kunye neoyile okanye nantoni na efuna ukulungiswa komphezulu phambi kokufaka ipeyinti okanye nayiphi na into yokugquma. Ke kwinkqubo yokuqhushumba kwesanti, imidiya ye-sandblasting ikhawuleziswa nge-pneumatically ngomoya ocinezelweyo (endaweni ye-centrifugal turbine). Isanti okanye enye i-abrasive idlula ityhubhu eqhutywe ngumoya oxinzelelweyo, evumela umsebenzisi ukuba alawule indlela yokuqhuma, kwaye ekugqibeleni iqhume nge-nozzle kwinxalenye.

Ukudubula kwe-shot kukusebenzisa i-impeller ejikelezayo enesantya esiphezulu ukuphosa intsimbi encinci okanye i-iron shot encinci, kwaye ibethe umphezulu wenxalenye ngesantya esiphezulu, ngoko umaleko we-oxide ophezu kwendawo unokususwa. Kwangaxeshanye, ukudutyulwa kwentsimbi okanye ukudubula kwentsimbi kubetha umphezulu wenxalenye ngesantya esiphezulu, nto leyo ebangela ukuba i-lattice igqwetheke kumphezulu wenxalenye ukunyusa ubulukhuni bomphezulu. Yindlela yokucoca umphezulu wenxalenye ukuqinisa ngaphandle.

Ngaphambili, ukuqhushumba kwesanti kwakuyeyona nkqubo iphambili yokuqhushumba kunyango lwe-abrasive. Isanti yayifumaneka ngokulula kunezinye imidiya. Kodwa isanti yayinemiba efana nokufuma eyenza kube nzima ukusasazeka ngomoya ocinezelweyo. Isanti nayo yayinongcoliseko oluninzi olufumaneka kwizinto zendalo.

Owona mceli mngeni wokusebenzisa isanti njengesixhobo esirhabaxa ziingozi zempilo. Isanti esetyenziswa kwisanti yokuqhunyiswa yenziwe ngesilica. Xa uphefumlelwa amasuntswana esilika ahlala kwinkqubo yokuphefumla enokuthi ibangele izigulo eziqatha ezifana nothuli lwe-silica yaziwa njengomhlaza wemiphunga.

Umahluko phakathi kokuqhunyiswa kwesanti kunye nokuqhushumba kwegrit okanye okubizwa ngokuba kukudutyulwa kuxhomekeke kwindlela yokusetyenziswa. Apha, inkqubo yokuqhunyiswa kwesanti isebenzisa umoya ocinezelweyo ukudubula imidiya erhabaxa umzekelo isanti ngokuchasene nemveliso eqhushumbayo. Ukudubula kusebenzisa amandla aphakathi kwisixhobo somatshini ukuqhubela phambili uqhushumbo lweendaba kwindawo.

Ngokubanzi, ukudutyulwa kusetyenziselwa iimilo eziqhelekileyo, njl. njl., kwaye iintloko ezidubulayo ezininzi zihlangene phezulu nasezantsi, ekhohlo nasekunene, kunye nokusebenza okuphezulu kunye nongcoliseko oluncinci.

Ngokuqhunyiswa kwesanti, isanti iqhubeleka phezu komhlaba. Ngokudubula kweembumbulu, kwelinye icala, iibhola zentsimbi ezincinci okanye amaso ajikeleziswa kumphezulu. Iibhola okanye amaso ahlala enziwe ngentsimbi engatyiwa, ubhedu, ialuminiyam okanye i-zinc. Nokuba kunjalo, zonke ezi zinyithi ziqinile kunesanti, zenza ukuba ukudubula kuqhume kusebenze ngakumbi kunomlingane wayo wokuqhunyiswa kwesanti.

Ukushwankathela, ukuqhushumba kwesanti kuyakhawuleza kwaye kunoqoqosho. Ukuqhushumba kwembumbulu yinkqubo yonyango ebandakanyekayo kwaye isebenzisa izixhobo eziphucukileyo. Ke ngoko, ukudubula kucotha kwaye kubiza kakhulu kunokudubula kwesanti. Nangona kunjalo, kukho imisebenzi engenakukwazi ukusingatha i-sandblasting. Emva koko, ukhetho lwakho kuphela kukuya kuqhushumba.
