Sandblasting nakazi gakoresha umwuka wifunitse nkimbaraga zo gusunika abrasives hejuru yumurimo wo gutunganya. Ibi nibyo bita sandblasting, nibyo dukunze kwita kurasa. Kuberako muminsi yambere yo guturika kurasa, umucanga nicyo cyonyine cyashoboraga gukoreshwa, bityo guturika kurasa byitwa guturika umucanga muricyo gihe kandi igihe kinini nyuma yacyo. Umusenyi urashobora gutuma ubuso bugomba gusukurwa bukabona isuku isabwa hamwe nuburangare runaka, kandi bikanoza guhuza igifuniko hejuru. Nubwo igifuniko cyaba cyiza gute, ntigishobora kwomekwa hejuru yumurimo utabanje kuvura igihe kirekire. Intego yo kwitegura hejuru ni ugusukura hejuru no gutanga ububi busabwa "gufunga" igifuniko hejuru. Nyuma yubuso bwumucanga wumusenyi ushyizwe hamwe ninganda zikora neza, ubuzima bwumurimo bwikubye inshuro 3,5 kurenza ubuzima bwumurimo bwuburinganire bumwe hejuru yubutaka hakoreshejwe ubundi buryo. Iyindi nyungu yo kumena umucanga (guturika kurasa) nuko ubukana bwubuso bushobora kugenwa hakurikijwe ibisabwa kandi bishobora kugerwaho mugihe cyogusukura.
Ubukonje, nkurugero, inzira aho aicupa ryo kwisigaihinduka neza kandi ihinduka matte. Umucyo urabagirana hejuru kugirango ugaragaze diffuse. Mu bukonje bwa chimique, ikirahuri ni ubutaka cyangwa intoki hamwe na emery, umucanga wa silika, ifu yamakomamanga nibindi bikoresho kugirango bibe hejuru yubusa, cyangwa ikirahure nibindi bintu bishobora kuvurwa hakoreshejwe aside hydrofluoric kugirango ikore ikirahure gikonje.
Ubukonje ndetse n'umucanga byombi bikoreshwa mu gupfuka hejuru yikirahure, kugirango urumuri ruzagenda rusa neza nyuma yo kunyura mu itara. Biragoye kubakoresha bisanzwe gutandukanya ubwo buhanga bubiri. Ibikurikira bisobanura uburyo bwo gukora ubwo buhanga bubiri nuburyo bwo kubumenya.
1. Inzira yo gukonja
Ubukonje bivuga kwibiza ikirahuri mumazi ya acide yateguwe (cyangwa ugashyiraho paste acide), kwangirika hejuru yikirahure hamwe na aside ikomeye, hamwe na hydrogène fluoride ammonia mumuti ukomeye wa acide itera hejuru yikirahure gukora kristu. Kubwibyo, niba uburyo bwo gukonjesha bukozwe neza, hejuru yikirahure gikonje kiroroshye cyane, kandi kristu yatatanye itanga ingaruka mbi. Niba ubuso bugereranije, ibi byerekana ko aside irimo kwangiza cyane ikirahure, cyangwa bimwe muribi ntibifite kristu. Ikiranga iyi nzira ni isura ya kirisiti irabagirana hejuru yikirahure cyakozwe mubihe bikomeye. Impamvu nyamukuru nuko hydrogène fluoride ammonia imaze kumara. Kugirango ugere kuriyi leta, abayikora benshi bagerageje nubushakashatsi bwinshi, ariko ntibashoboye gutsinda iyi ngorane.
2. Ikoranabuhanga rya sandblasting
Ikoresha ibice byumucanga byatewe nimbunda ya spray kumuvuduko mwinshi kugirango ikubite hejuru yikirahure kugirango ikore neza neza, bityo igere ku ngaruka zo gukwirakwiza urumuri, no gukora ibyiyumvo bibi iyo urumuri runyuze. Ubuso bwibicuruzwa byikirahure byakozwe nuburyo bwo kumusenyi birakabije. Kuberako ubuso bwikirahure bwangiritse, busa nikirahuri cyera ukurikije fotosensitivite yikirahure kibonerana.
Inzira zombi ziratandukanye rwose. Ikirahure gikonje gihenze kuruta ikirahuri cyumusenyi, kandi ingaruka ahanini ziterwa nibyifuzo byabakoresha. Ibirahuri bimwe bidasanzwe ntibikwiriye gukonja. Urebye kubikurikirana, matte igomba guhitamo. Igikorwa cyo kumusenyi kirashobora gukorwa munganda rusange, ariko inzira yo kumusenyi ntabwo yoroshye gukora neza.
