I-Sandblasting ngumsebenzi osebenzisa umoya ocinezelweyo njengamandla okutyhala i-abrasives kumphezulu we-workpiece ukuze iqhutywe.Le yinto ebizwa ngokuba yi-sandblasting, nto leyo esihlala siyibiza ngokuba yi-shot blasting.Ngenxa yokuba ngemihla yamandulo yokuqhushumba kwentlabathi yayikuphela kwentlabathi eyayinokusetyenziswa, ngoko ukudubula kwesanti kwakubizwa ngokuba kukuqhushumba kwesanti ngelo xesha nakwixesha elide emva koko.I-Sandblasting inokwenza ukuba umphezulu ucocwe ufumane ukucoceka okufunekayo kunye noburhabaxa obuthile, kunye nokuphucula ukunamathela kwengubo kwisiseko sesiseko.Kungakhathaliseki ukuba i-coating intle kangakanani, ayinakuqhotyoshelwa kumphezulu we-workpiece ngaphandle kokunyanga kwexesha elide.Injongo yokulungiswa komphezulu kukucoca umphezulu kunye nokuvelisa uburhabaxa obufunekayo "ukutshixa" isambatho phezu komhlaba.Emva kokuba umphezulu we-sandblasted workpiece ufakwe kwi-coating ye-industrial esebenzayo, ubomi benkonzo ye-coating buyi-3.5 ubude kunobomi benkonzo yomgangatho ofanayo womgangatho ophathwayo ngezinye iindlela.Enye inzuzo ye-sandblasting (i-shot blasting) kukuba uburhabaxa bomphezulu bunokumiselwa kwangaphambili ngokweemfuno kwaye bunokufezekiswa ngexesha lokucoca.
Iqabaka, umzekelo, yinkqubo apho aibhotile yeglasi yokuthambisaiyagudiswa kwaye ibe matte.Ukukhanya kukhanyisela umphezulu ukwenza umboniso osasazekileyo.Kwikhemikhali yokukhenkceka, iglasi igutywa ngoomatshini okanye igaywe ngesandla nge-emery, i-silica sand, ipomegranate powder kunye nezinye izinto ezirhabaxa ukuze zenze umphezulu orhabaxa ngokufanayo, okanye iglasi nezinye izinto zinokunyangwa ngesisombululo se-hydrofluoric acid ukwenza iglasi eqabaka.
Zombini i-frosting kunye ne-sandblasting zisetyenziselwa ukugquma umphezulu weglasi, ukuze ukukhanya kuya kusasazeke ngokulinganayo emva kokudlula kwisibane sesibane.Kunzima kubasebenzisi abaqhelekileyo ukwahlula phakathi kwezi teknoloji zimbini.Oku kulandelayo kuchaza iindlela zokuvelisa ezi teknoloji zimbini kunye nendlela yokuchonga.
1. Inkqubo yokukhenkceza
Ukukhenkceza kubhekiselele ekuntywiliseleni iglasi kulwelo lweasidi elungisiweyo (okanye ukusebenzisa intlama yeasidi), ukugrulisa umphezulu weglasi ngeasidi eyomeleleyo, kunye nehydrogen fluoride ammonia kwisisombululo seasidi eyomeleleyo ibangela ukuba umphezulu weglasi wenze iikristale.Ngoko ke, ukuba inkqubo yokukhenkceza yenziwe kakuhle, ubuso beglasi enqabileyo bulula kakhulu, kwaye iikristale ezihlakazekileyo zivelisa umphumo obumnyama.Ukuba umphezulu urhabaxa noko, oku kubonisa ukuba iasidi ikhukulisa kakhulu iglasi, okanye ezinye zazo azikabinazo iikristale.Uphawu lwale nkqubo kukubonakala kweekristale ezicwebezelayo kwiglasi eyenziwe phantsi kweemeko ezinzima.Esona sizathu sikukuba ihydrogen fluoride ammonia phantse ityiwe.Ukuze ufezekise lo mbuso, abaninzi abavelisi baye benza imizamo emininzi kunye nezifundo, kodwa abazange bakwazi ukunqoba lo bunzima.
2.Itekhnoloji yokuqhunyiswa kwesanti
Isebenzisa amasuntswana esanti akhutshwa ngumpu wokutshiza ngesantya esiphezulu ukubetha umphezulu weglasi ukwenza umphezulu ocolekileyo ongalinganiyo, ngaloo ndlela uphumeza isiphumo sokusasazeka kokukhanya, kwaye yenze imvakalelo enobumdaka xa ukukhanya kudlula.Umphezulu weemveliso zeglasi eziveliswa yinkqubo ye-sandblasting rhabaxa.Ngenxa yokuba umphezulu weglasi wonakele, ukhangeleka njengeglasi emhlophe ngokumalunga ne-photosensitivity yeglasi yeglasi yokuqala.
Ezi nkqubo zimbini zahluke ngokupheleleyo.Iglasi ekhenkcezayo ibiza kakhulu kuneglasi yesanti, kwaye umphumo uxhomekeke ikakhulu kwiimfuno zabasebenzisi.Ezinye iiglasi ezikhethekileyo azifanelekanga kwiqhwa.Ukujonga kwinjongo ebalaseleyo, i-matte kufuneka ikhethwe.Inkqubo yokuqhunyiswa kwesanti inokwenziwa kwiifektri ngokubanzi, kodwa inkqubo yokuqhunyiswa kwesanti ayilula ukwenza kakuhle.
