Yeyiphi iGrit Sandpaper yokuPolisha iMetal?

Ukupolisha ngesinyithi

Ukupolisha ngopende wesinyithi yindlela esetyenziselwa ukucokisa umphezulu wesinyithi emva kokupeyinta, idlala indima ephambili ekuphuculeni ukuqina kunye nokubonakaliswa ngokubanzi. Le nkqubo icwangcisiweyo ibandakanya ukugawula nokuguqula umphezulu wesinyithi ukuze kususwe iziphene kunye neebharrs, ngaloo ndlela kuphuculwe ukuguda, amandla, kunye nobude bexesha. Ipolishi yokutshiza ngesinyithi isebenza injongo ezimbini zokuphucula ukusebenza kunye nokubonakala kwesinyithi. Inqanaba lokupolisha liphucula kakhulu ukuthembeka kwesakhiwo kunye nokusebenza kwesinyithi ngokususa iziphene kunye nokungahambi kakuhle okuhlala kwenzeka ngexesha lenkqubo yokupeyinta.

Ukususwa kweziphene kunceda ekuthinteleni ukugqwala kwaye kuqinisekisa ukuba isinyithi sinokumelana neemeko ezinzima zokusingqongileyo ngaphandle kokubeka amandla ayo esichengeni. Ukongeza, ukupolisha kuvelisa umphezulu ogudileyo nokhazimlayo onegalelo kubuhle obubonakalayo. Le nkqubo ilungisa isinyithi kwaye isinika inkangeleko egudileyo enomtsalane emehlweni.

Khetha iphepha lesanti elifanelekileyo

Xa uqalisa uhambo lokutshiza ipeyinti yesinyithi, khetha eyona ifanelekileyoiphepha lokusantiingadlala indima enkulu ekufumaneni iziphumo ezigqwesileyo. Kubalulekile ukuqonda ukubaluleka kwe-sandpaper grit njengoko imisela ubungakanani be-grit kunye nobungakanani bomonakalo enokuwubangela kumphezulu wesinyithi. I-sandpaper iza ngobukhulu obahlukeneyo be-grit, nganye isebenzela injongo eyahlukileyo kwinkqubo yokupolisha. Makhe sihlolisise iintlobo ezintathu eziphambili ze-sandpaper kunye neenzuzo ezizisa ekupeyinteni isinyithi.

Iphepha lesanti elirhabaxa (60~120 mesh): Lenzelwe ukususa iziphene ezibonakalayo ezifana nomhlwa, amaqhuma, kunye nemingxuma, iphepha lesanti elirhabaxa lolona khetho lokuqala lokususa iziphene ezibonakalayo kwiindawo zesinyithi. Uthuli olukhulu olukummandla wephepha lesanti elirhabaxa lususa ngokufanelekileyo izixa ezikhulu zesinyithi, nto leyo ebangela ukuba ipolish ibonakale ngakumbi. Eli phepha lesanti lisetyenziselwa ukulungiselela iindawo zesinyithi ukuze ziphuculwe ngakumbi.

Iphepha lesihlabathi eliphakathi (180~320 mesh): Iphepha lesihlabathi eliphakathi lilungele ukuthambisa iindawo zesinyithi kwaye lisusa ngempumelelo ii-burrs kunye namaqhuma amancinci. Ukusebenzisa eli phepha lesihlabathi kuqinisekisa ukugqitywa okugudileyo nokucokisekileyo kwiindawo zesinyithi kwaye kuphucula ukukhanya nokukhanya. Ubungakanani bephepha lesihlabathi eliphakathi bubonisa ubume obucokisekileyo kwaye bunokuphucula kancinci kancinci iimpazamo, nto leyo ekhokelela ekubeni umphezulu ubonakale ucolekile.

Iphepha lesitshizi elicolekileyo (elingaphezulu kwama-400 grit): Ukuze kulungiswe umphezulu wesinyithi ngokususa iziphene ezincinci ezifana namabala amanzi kunye nezinye iziphene, iphepha lesitshizi elicolekileyo sisixhobo esibalulekileyo. Iintlama zesanti kumphezulu wephepha lesitshizi elicolekileyo zincinci kakhulu, ukuqinisekisa ukuba akukho monakalo wesibini owenzekayo kumphezulu wesinyithi ngexesha lokupolisha. Ukusebenzisa iphepha lesitshizi elicolekileyo kunika ukugqiba okuchanekileyo, kuphucula ukusebenza kwepeyinti yokutshiza ngelixa kubonelela ngokhuseleko olongezelelweyo kumphezulu wesinyithi. Ukukhetha iphepha lesitshizi elifanelekileyo ukuze kufezekiswe isiphumo esifunekayo kubalulekile ekufezekiseni iziphumo ezilungileyo zokupholisha ipeyinti yesinyithi.

Ukwenza ngokwezifiso ulwelo lwephepha lakho lesanti ngokweziphene ofuna ukuzilungisa kuvumela ukupholisha okusebenzayo nokufanelekileyo, okubangela umphezulu wesinyithi ogqibeleleyo. Kubalulekile ukukhumbula ukuba nokuba ukhetha bungakanani ulwelo, kufuneka uqaphele xa upholisha umphezulu wesinyithi. Iindlela ezifanelekileyo kufuneka zisetyenziswe, kubandakanya uxinzelelo olulawulwayo kunye nokuhamba rhoqo, ukuqinisekisa ukuba izinto ezininzi azisuswa kwaye kuthintelwe ukonakalisa isinyithi.

Lilonke, ukukhetha iphepha lesanti elifanelekileyo linyathelo elibalulekileyo ekufumaneni iziphumo ezintle xa kupeyintwa ipeyinti yesinyithi. Ngokuqonda ubungakanani begrit kunye nemiphumo yayo ehambelanayo, abantu banokukhetha iphepha lesanti elifanelekileyo ukujongana neziphene ezithile. Nokuba bakhetha iphepha lesanti elirhabaxa, eliphakathi, okanye elincinci, abasebenzisi banokucoca imiphezulu yesinyithi kwaye baphucule ukusebenza kwepeyinti ngelixa bekhusela ukuthembeka kwesinyithi. Ngobuchule kunye nobuchule obufanelekileyo, iphepha lesanti elifanelekileyo linokuguqula umphezulu wesinyithi, liphucule inkangeleko yaso kwaye liphucule umgangatho waso ngokubanzi.

Amanyathelo okuzikhusela xa kupholishwa isinyithi

Ukufikelela kwisiphelo esigqibeleleyo xa kufikwa ekupolisheni ngesinyithi kufuna okungaphezulu nje kobuchule obunobuchule. Kufuna ingqalelo kwiinkcukacha kunye nokuthobela uthotho lwezilumkiso ezibalulekileyo. Nokuba ungumqali okanye umqhubi onamava, ukukhumbula la manqaku alandelayo kuya kukunceda ufumane iziphumo ezigqwesileyo ngelixa uqinisekisa ukuba umphezulu wakho wesinyithi uhlala ixesha elide kwaye uthembekile.

Ukukhetha iphepha lokutshiza elichanekileyo: Enye yezona zinto zibalulekileyo ekupolisheni ngesinyithi kukukhetha iphepha lokutshiza elichanekileyo. Amaphepha okutshiza ahlukeneyo aneempawu ezahlukeneyo zokurhawuzelela, ngoko ke ukukhetha elifanelekileyo kumsebenzi okhoyo kubalulekile. Ngokuxhomekeke kubukhulu bokungagqibeleli kunye nokugqitywa okufunwayo, khetha iphepha lokutshiza elirhabaxa, eliphakathi, okanye elincinci. Khumbula, ukufanisa ulwelo kunye nokungapheleli kwephepha lokutshiza kuya kukunceda ufumane iziphumo ozifunayo.

Ukuqina kokusila okunengqiqo: Ukugcina amandla okusila afanelekileyo kubalulekile ukuze kuthintelwe umonakalo wesibini kumphezulu wesinyithi. Ukusebenzisa uxinzelelo olugqithisileyo okanye ukusebenzisa iphepha lokusila elirhabaxa kakhulu kunokususa izinto ezingaphezulu kunokuba bekucetyiwe kwaye kunokonakalisa ukuthembeka kwesinyithi. Ukuze kubekho indlela elungeleleneyo, sebenzisa uxinzelelo olulawulwayo kwaye uvumele iphepha lokusila lisebenze kancinci kancinci. Oku kuya kuqinisekisa iziphumo ezihambelanayo ngaphandle kokuchaphazela amandla esinyithi.

Icala lokusila elingaguqukiyo: Ukusila kwicala elichanekileyo lolunye ukhuseleko oluqinisekisa ukugqitywa okuphezulu ngelixa kugcinwa ubume bokuqala besinyithi. Icala lokusila kufuneka lihambelane necala lesinyithi ukuqinisekisa ukubonakala okufanelekileyo nokulinganayo. Ngokuhlala ulandela ibala lesinyithi, umphezulu ocoliweyo uya kuba nembonakalo efanayo nentle ngaphandle komonakalo ongafunekiyo.

Beka phambili ukucoca ngokucokisekileyo: Emva kwenkqubo yokupolisha, kubalulekile ukucoca umphezulu wesinyithi kakuhle ukuthintela ukuba iintsalela zesinyithi kunye nesanti zingachaphazeli inkqubo yokupeyinta elandelayo. Ukungaphumeleli ukucoca imiphezulu ngokwaneleyo kunokubangela ukuba ipeyinti inamathele kwaye ingalingani. Sebenzisa ibrashi ethambileyo okanye umoya ocinezelweyo ukususa naziphi na iinxalenye ezikhululekileyo ukuqinisekisa ukuba umphezulu wesinyithi uhlala ucocekile ukuze ugqitywe kakuhle.

Isiphelo

Ipeyinti yokutshiza ngesinyithi epholishayo ifuna ukukhethwa kwephepha lokupholisha elifanelekileyo. Ngokubanzi, iphepha lokupholisha elirhabaxa lifanelekile ukususa iziphene ezicacileyo kunye neziqwenga, iphepha lokupholisha eliphakathi lisetyenziselwa ukupholisha umphezulu othambileyo nothambileyo, kwaye iphepha lokupholisha elincinci lisetyenziselwa ukususa iziphene ezincinci kunye nokukhusela umphezulu wesinyithi. Ngexesha lenkqubo yokupholisha, kufuneka unikele ingqalelo ekukhetheni ngokufanelekileyo iphepha lokupholisha kunye neenkcukacha zokupholisha, ezinokuphucula umgangatho kunye nobomi benkonzo yemveliso egqityiweyo.
