Kungani Ukuthutha Kwegrit Kuyakha Iqquality Yokuphahla Kwesiliva

Ubuciko: Ukungahambeki KweSonto (RMS) Nenkinga Yakho Yobunikwano Bokulibala

Ubuncinci bokuvila, obalwa ngolimi olwaziwa njenge-Root Mean Square noma RMS emikrometha, kubangela konke ukuthi kanjani imvula ivusa kuwo. Xa kusebenziswa izimboni, izikhumba ezikhulu ezingaphansi kuka-50 ukuya ku-400 zisetshenziselwa ukususa izikhumba ezinkulu ezingaphezu kuka-5 mikrometha. Emva koko kufika umsebenzi omuhle ongeno-800 ukuya ku-3000 futhi, okuphulaphulisa izinkinga ezincane ukuze zilahlwe kabusha ezindaweni eziphansi kuka-0.1 mikrometha noma ngaphansi. Izinhloso zibonisa ukuthi uma izihlangothi zifinyelela igama le-RMS phansi kuka-0.1 mikrometha, zazinzima izigaba ezingu-90 zomlando, okwabizwa ngokuba yisiqukumelo esiphumelelayo sokuvumazane. Uma umuntu akhohlwa ezimcabanweni engeyiyo, kunemeko yokuba kuhlale khona izimbambano ezincane ezingaphansi kuka-0.3 mikrometha. Lezi ziphazanyo ezincane zivumazane imvula esikhathini sezovumazane, zenza into etholakala njengobuso obungelili. Lokhu akuyiki kuphela kodwa kakhulu kakhulu amabhizesi ngama-30% ngexesha nezimali ekufuneka kuzozama ukulandela wonke umyalelo wokusebenza kuye kuye kuyo yona ngalinye igama le-grit.

Ubunzima Bezingqondo: Indlela Uminerali Wempofu (Granite, Marble, Limestone) Ithinta Ngayo Amathresihidi AseGrit

Ubushushu nobungakanani bokugula bekakhulu kwezintonga ezahlukene kube yidingeka ukuthi singenje njani izigaba esizodinga ukusebenzisa xa sisebenza ngazo. Ngokomzekelo igrenayithi inamathuba athile (mangalishi 7), ngakho-ke kudingeka siqale nento ethintana kakhulu, njenge-50 kuya ku-100, ukuze sifake isilinganiso esihle. I-marble indoda yamanye amazwi. Ngoba ingezansi kakhulu (mangalishi 3 noma 4), ukuphindeka kakhulu ngokugcwele kungahlasela umfanekiso futhi kuthintele isibhakabhaka. Sathatha lokhu kakhulu emnyango wethu. I-limestone inesimo esisha ngoba yenziwa ngamanxeba amakhulu. Xa usebenza ne-limestone, abasebenzi abaningi basebenzisa izigaba zingama-1500 ukuze kunjalo resin ikhulule manxeba ngaphambi kokuba iphumelela ekupholisheni kokugcina. Ungakwazi ukubala ngokufanayo i-travertine! Izinhloso zibonisa ukuthi ukwenza phutha kusigaba sikagrigidi kungenza ukuthi kuhlale kunezikhathi eziphakade kumathuba angu-40%. Lokhu kuyindlela yonke into enezinto ezahlukene xa kufanele kugunyazwe nokupholisha.

Ukulandela lezi zilinganiso kusungula ukulahlekelwa kwesimo phansi nokuthutha okuphezulu kokugcoba ngokudla.

Indlela Echasisayo Yokuthutha Kwesilinganiso Ye-Grit Ukufakelwa Okumelene Ngezikhathi Ezimbiyela

Isikhashana 1: Kude kuya kude (50–400 Grit) – Ubunzima kanye Njikeleza ye-Macro

Qala ngokusebenzisa i-diamond pads ezingu-50 kuze kube ngu-100 grit uma usebenzela izinxenye ezingavumilekile kanye nazo zinkimbili eziningi. Kukhona indlela yokuthola ubunzima ukuba singathola imiphumo emihle yonke emva kwalokho. Kamva uhambe kancane kancane kuze kube ngu-200 kuze kube ngu-400 grit ukuze uthinthe wonke lo msebethe owodlulile. Uma umuntu akuphazanyise le sizinda noma angedlule ngokushesha, uzothola iqhibitho elingalunganga futhi angeke alithandi, kunye nomsebethe oyinzuzo ongaba ngu-halfe yenhlathi ekugcineni isikhathi. Hlanjwa inqwelo ekugcineni kwe-polishing futhi ungahlawuleli kakhulu. Ukunqoba okuningi kungenza indimba njenge-hate damage noma izinwele ezincane ezivaleka kumongo.

Isikhashana 2: Ukucophelela Okuncane (800–1500 Grit) – Ukuqina Okuncane Kanti Ukuqina Kwesizinda

Ukushintsha kuma-pads angele 800 kuya ku-1500 kusiza ekutholeni kwalezi zindiza ze-subsurface stress ezikhomba ngokungahlabiwa noma kube yonke into ihlabile. Sebenzisa izikhala eziphambili ngokuphindaphindiwe ngo-1200 RPM ukuze uthole izishayani eziqhubekayo kuleyi sondo futhi uvikele indlela eyashiywe yokubuka okuhlekile. Ngokwesilinganiso sethu, lokho kuphela kusenzo lukhulisa ububi bokubuka kabusha ngaproximately 35% ngaphambi kokubuffa. Emva kwezinyathelo ezimbalwa, hlanjula isandla ngendlela enemphefumulo engcono ukuqinisekisa ukuthi zonke izishayani zilahlekelwe kabusha ngaphambi kokuba usuke esigabeni sesilandela.

Isigaba 3: Ukupolisha Okunamandla (2000–3000+ Grit + Buffing) – UkuFinyelela ≥90 GU Isibonakaliso Esikhulu

Gcina ngamapadi aphuthakathiwe ngezikhathi kusuka ku-2000 ukuya ku-3000 grit bese uhambe ku-resin buffing engaphathelani. Lokhu kwenza kuyokuthi kuthumele izithule zikamanga ezincane ukuze ziphenduke imini ngendlela efanelekileyo. Akuyona kuphela umsebenzi wokwenza into ibaluleke kodwa ukufinyelela iqembu eliqondile ekugcineni. Cindezela okungenani amagloss units angu-90 owafakiwe ngemisebenzi ebomvu emhle njengoba konke okunciphana kokuba khona akuyona ikhefana naleyo ekhethekile ekugcineni kwamakhilomitha. Xa usebenza namaduli atholakala njenge-marble, uzimisela ungafiki ku-2000 grit ngoba ukugaya okuningi kungayihlukutshela indawo yasendleleni yesithulwana ngexesha elide. Gcina konke ngodumo olunjalo xa ufika ekugcineni kwe-buffing. Umyalezo wena ubonisa ububi, ubenza isandla sibe libaluleke kakhulu, kwaye unika umdla wenkohlaka xa uhlandela.

Ukuzila Izimistiko Ze-Grit Progression Ezibangela Ukuphula Kwesimo

Ukungahoyi: Xa ‘Ukuhamba’ Kusuka Ku-400 Iya Ku-1500 Grit Kubangela Ukuphula Nezidingo Zokusebenza

Uma umuntu eshayelela lezi zikhathi eziphakathi, ikakhulu indawo ebalulekileyo ye-800 grit, kutheni okuthiwa? Isayizi siyophazanyiswa ngamaphansi amahle angakhetha izibalo kulokho kube khona isimilo esihlukahlukene esingathandakali. Ukubuya ngokushesha kusuka ku-400 ku-1500 grit kungalungisa futhi. Kuyashiyela amaphasi amancane namadots angumqoka kumongo, lokhu kusho ukuthi kumele ubuye ucocezelele emva. Futhi masithi, ukulungisa izimo kuthinta ixesha nezemali - sizashiyela kusukela ema-30 kuze kube nemihla engu-50 yokusebenza kuphela ukuze ulungele okufanele kwenzeke ngokuqala. Inhlalo yonke iphatha ukulungisa okwenzekayo ngaphambilini. Uma ushayelela inhlalo yonke yesimo, isistimu sonke siphazanyiswa. Abasebenzi basezintshukumo bayazi lokhu kangakanani. Ngokuphawula ku-granite ne-quartzite, ukulandela umbhalo otholakala we-400 emva kwalokho 800 bese ku-1500 grit akuyona kuphela into efuna, kodwa kungenzeka kuyinto ekudingekayo uma isinqumo sokugcina singafuneki sibe yiprofeshinali.

Ukungcola Kwakhulu Okungcolileyo: Kutheni Ukusebenzisa I-Grit Eningi kune-3000 Kwenza Kuphephele Intonga (Idatha ye-ASTM C97)

Ukudla ngaphezu kwezidingo zomthwalo ngokuvamile xa kufakwa imigqa engama-grit yindlela yokukhula iziphumo. Ngokwizibonelo zokuchaza njenge-ASTM C97, ukusebenzisa lokho kungaphansi kwe-3000 grit kumathwala amancane njenge-marble, travertine, noma limestone kusenza iingxaki. Lo ndlela uyakha intando enkulu kakhulu kwaye ube uneempawu encinci azinokunciphisa ubulukwana kabusha phakathi kwe-15 kunye ne-25%. Kuloo maxabiso emathwaleni, isiphumo esilungileyo sibaluleka phakathi kwe-1500 kunye ne-2000 grit. Ukuphuma ngaphezulu koko kukhula ukubanda komthwalo wakhe onjalo ohlelwe ngakumbi ngu-calcite okanye dolomite. Amagquba aphethayo kunye nezinto ezenziwe ze-quartz aziqhubeka ngokwahlukileyo. Le migaqo enobumba akayikhandlani kuphela kodwa futhi ihlawula le mgca enobumba aphakathi kwe-3000 ngaphandle kokuthintelwa konke ekugqibeleni kwesandla.

Indlela Ethathe Iimpawu Yokukhetha Umgaqo Wokunxulumana Ngokwahluka Kwemithwalo

Akukhohlakali ukulungiselela ukuthi i-grit efanayo ibe yisivinini esifanayo uma kufunwa ukufakwa okuhle. Kumaquba we-granite ne-quartzite, kumele sifike kuwo wonke amagrit kusukela ku-50 bese siyayandula ku-100, 200, 400, 800, 1500 bese ekugcineni siyafika ku-3000+. Lokhu kusiza ekusebenziseni kwalokho kristale eziphelele ngaphansi kwesihlangothi ngaphandle kokudala izikhumba ngaphansi. Amaguba we-marble ne-limestone ayahluke, ayingekile ukuthi isingeni sokuthembeka kube nge-200 kanye nge-400 ngokulandelana, kwaye kungakhathalwa ukupholisha phakathi kwe-1500 kanye ne-2000 ukugcina umgca wabo futhi ubeke ubuchwepheshe obuhle. Uma usebenzisa i-quartz eqashelwe, kukhona okuthile okhazimulayo ngokwenza i-dry polish enguqukayo ngenkinga ye-3000 ukuvikela uhlelo lwesilingo. Uma ushiya isinyathelo esisodwa kulolu daba, nokuthi kuphela okunye, lokhu kuyakhiqiza isiphetho esingavamile futhi kumele sibuyele kusebenza kabusha ngama-40% ngokusho kwezinhlobo ze-ASTM mayelana nemithetho yesihlangothi. Ukuze uhlawule kube yini yonke ihlelekile, shaya kuphela igloss meter. Inkinga enezinguqu eziningi kune-90 GU ikhombisa sithole isiphetho esifanayo no-mirror abaningi bathanda.
