Uma usebenza ngamatshe, ukukhetha usayizi ofanele we-sandpaper grit kubalulekile ekufezeni ukuqeda kanye nekhwalithi oyifunayo. I-sandpaper grit ibhekisela kusayizi wezinhlayiya ezihudulayo ezifakwe ephepheni, okuthinta ngqo ikhono lalo lokugaya, ukubumba, nokupholisha ubuso betshe. Lesi sihloko sinikeza umhlahlandlela ophelele we-sandpaper grit.
Ukuqonda i-Sandpaper Grit
Usayizi wohlamvu lwephepha lesihlabathi ulinganiswa ngenani lezinhlayiya ezirhabaxa nge-intshi yesikwele ngasinye sephepha lesihlabathi. Amahlamvu aphansi makhulu futhi aqinile, kanti amahlamvu aphezulu mancane futhi acwebezelayo. Ukukhetha usayizi wohlamvu olufanele kubalulekile kuzo zonke izigaba zokucubungula amatshe, kusukela ekugayweni kokuqala kuya ekupholishweni kokugcina.
Ukuhlelwa Kwegridi Nokusetshenziswa
Ukugaya okuqinile (i-mesh engu-40-120)
Isihlabathi esiqinile sisetshenziselwa ukususa izinto ezisindayo kanye nokulungiselela ubuso bokuqala.
Ama-grit angu-40-50: Le grit ilungele ukwelapha izindawo zamatshe aqinile kusengaphambili. Isusa ngempumelelo ama-burrs asikiwe, imithungo engaqondile, kanye nezinye izinkinga ezibonakalayo ebusweni. Lesi sigaba sibalulekile ekulungiseleleni itshe ukuze licutshungulwe ngokulandelayo.
Ama-grit angu-60-120: Lolu hlu lufanelekela ukugaya izinto eziyisisekelo njengemabula. Lusiza ukususa imihuzuko esobala futhi lulungiselela indawo ukuze kufakwe ama-sandpaper amahle, okuqinisekisa ukuthi ukuqeda kubushelelezi.
Ukugaya okuphakathi nendawo (i-mesh engu-180-400)
Itshe eliphakathi nendawo lisetshenziselwa ukwakheka nokucwengisisa okwesibili kobuso betshe.
I-grit engu-180-240: Le grit ilungele ukuqedwa kwesibili kwetshe, kufaka phakathi ama-chamfer e-countertop kanye nokushintshana phakathi kwezinto eziqoshiwe ezibunjiwe. Ivumela umsebenzi omuhle ngenkathi isasusa izinto ngempumelelo.
Ama-grit angu-320-400: Lawa ma-grit asetshenziselwa ukulungiselela i-substrate ngaphambi kokupholisha. Asiza ekususeni imifantu emincane futhi alungiselele indawo yesigaba sokugcina sokupholisha, okuqinisekisa ukuqeda kwekhwalithi ephezulu.
Ukugaya nokupholisha kahle (ama-grit angu-600 nangaphezulu)
Uhlaza oluncane lubalulekile ukuze kufezwe indawo ecwebezelayo necwengekile.
I-mesh engu-600-1000: Lolu hlu lusetshenziselwa ukunikeza itshe lokwenziwa ukuqeda okungacwebezeli. Lisetshenziswa kanye nokupholisha amanzi, lisiza ekuvimbeleni ukubola kombala futhi lithuthukise ukubukeka kwetshe lonke.
Ama-grit angu-2000-3000: Lawa ma-grit asetshenziselwa ukupholisha itshe lemvelo esibukweni, afinyelele ukukhanya okungu-90° noma ngaphezulu. Lesi sigaba sibalulekile ekudaleni isiphetho esiphezulu esiveza ubuhle bemvelo betshe.
Ama-grit angu-5000 nangaphezulu: Isebenzisa ama-grit amahle kakhulu ukususa imihuzuko yezinga eliphansi futhi ithuthukise ukunamathela kwezingubo ezivikela ukungcola. Leli zinga lokupholisha libalulekile ukuze kugcinwe ukubukeka nokuqina kwesikhathi eside kwetshe.
Ukukhetha Okungahlukumezi
Iphepha lokusanta le-aluminium oxide
Ukusetshenziswa: Leli phepha lokusanta lilungele ukusanta i-granite ejwayelekile kanye nethayela. Liyasebenziseka futhi liyasebenza emisebenzini eyahlukahlukene yokusanta.
Uhla Lwezinhlayiya: Iphepha lesihlabathi le-aluminium oxide livame ukuba nama-grit angu-120 kuya kwangu-800 futhi lifaneleka ekugayweni nasekuqedeni kokuqala.
Iphepha lokusandpaper le-silicon carbide
Ukusetshenziswa: Iphepha lesihlabathi le-silicon carbide lifaneleka kakhulu ekugayweni kahle kwe-quartz kanye netshe lokwenziwa. Uhlamvu lwayo olubukhali noluqinile lwenza kube ngcono ekutholeni ubuso obubushelelezi.
Uhla Lwezinhlayiya: Leli phepha le-sandpaper liza ngohla lwezinhlayiya oluphakathi kuka-400 no-3000, okwenza libe lilungele ukupholisha nokucwenga izindawo.
Iphepha lokusanta ledayimane
Isicelo:Iphepha lokusanta ledayimaneisetshenziselwa ukupholisha amatshe ayigugu kahle kakhulu. Izinhlayiya zayo zedayimane zinobulukhuni obuhle kakhulu futhi zihlala isikhathi eside.
Uhla Lwezinhlayiya: Iphepha lesihlabathi ledayimane livame ukuba nezinhlayiya ezingu-5000 nangaphezulu, okwenza libe yindawo ekahle yokufeza ukuqeda okucwebezelayo ezindaweni ezithambile.
Amathiphu Okusebenzisa
1. Ukufanisa okuyisisekelo
Iphepha lokusanta elisekelwe yindwangu: Kunconywa ukusebenza okuqhubekayo okuqondile ngama-angle grinder aphathwa ngesandla. Ukuguquguquka nokuqina kwephepha lokusanta elisekelwe yindwangu kwenza lifanelekele izinhlelo zokusebenza ezahlukahlukene.
Iphepha lokusantisa i-resin: Iphepha lokusantisa i-resin alinamanzi futhi cishe alimhlophe ngesikhathi sokusantisa emanzini. Lesi sici siwusizo kakhulu uma kusetshenziswa amasu okusantisa amanzi.
2. Umhlahlandlela wokuthuthukisa ukukhuthazela
Umthetho wokugaya kabili: Uma usika, sebenzisa umthetho othi “ukugaya kabili”. Lokhu kusho ukuthi ukugaya ngakunye okulandelayo kufanele kube cishe kabili kunokwangaphambilini. Le ndlela isiza ukuqinisekisa ukuthi yonke imihuzuko yesigaba sangaphambilini isusiwe ngokuphelele.
Ukuhlolwa nokugcinwa: Uma imihuzuko isasele ngemva kwesigaba esisodwa, sicela uhlole ukuthi isondo lokugaya lithambile yini, uhlanze ikhanda elinemihlathi emithathu, bese ulungisa isikulufu sephedi yerabha ukuze ugcine ukusebenza kahle.
3. Ukulawulwa kwemfucuza
Ukugaya okuqinile: Uma ukugaya okuqinile, umgomo ukugcina imfucuza ingaphezulu kuka-2m2 ngeshidi elingu-30cm ubukhulu. Lokhu kusiza ekuphatheni ukusetshenziswa kwezinto nokuqinisekisa ukusebenza kahle.
Ukupholisha: Emisebenzini yokupholisha, imfucuza kufanele ikhawulelwe kumamitha-skwele angu-0.5 ngeshidi ngalinye. Lokhu kuphathwa kwezinsizakusebenza ngokucophelela kunganciphisa kakhulu izindleko.
Buyisela izinto ezonakele: Buyisela ngokushesha noma yiziphi izinhlayiya ezikrwada ezisusiwe noma i-substrate eyonakele ukuze ugcine ikhwalithi yomsebenzi wakho futhi uvimbele izinkinga ezengeziwe.
Ukwelashwa Kwamatshe Okukhethekile
Itshe elinomgodi
Amatshe anezimbobo, njenge-limestone kanye ne-sandstone, anezakhiwo ezihlukile ezidinga ukuphathwa ngokucophelela ukuze kugwenywe umonakalo ngesikhathi sokucubungula.
Ukusikwa okuqinile: Qala ngephepha lesihlabathi le-aluminium oxide elingama-grit angu-80 lokusikwa okuqinile. Leli phepha lesihlabathi lisusa ngempumelelo ukungapheleli kobuso futhi lilungiselele itshe ukwelashwa okulandelayo. Kulesi sigaba, kunconywa ukusebenzisa ukwelashwa okulwa nokungcola ukuze kuvinjelwe ukudaya kanye nomonakalo esikhathini esizayo.
Ukupholisha kahle: Ngemva kokupholisha kahle, shintshela ku-600 grit sponge sandpaper bese usebenzisa i-conditioner. Lesi sinyathelo sisiza ekufezeni ubuso obubushelelezi ngenkathi kulondolozwa ukuthungwa kwemvelo kwetshe. I-sponge sandpaper ifaneleka kakhulu etsheni elinezimbobo ngoba ihambisana nemingcele yobuso, inikeza ukupholisha okulinganayo.
Itshe lekristalu
Amatshe ekristalu njenge-granite ne-marble adinga indlela ehlukile ngenxa yobuningi bawo nokuqina kwawo.
Ukusikwa kokuqala: Qala ngokusebenzisa i-sandpaper engu-120-grit ukuze ulungise noma yikuphi ukungalungi kobuso. Ngemva kwalokho, khulisa kancane kancane ucezu lwe-sandpaper ≤50% ukuze ulawule isivinini sokusikwa. Le ndlela ikuvumela ukuthi ulawule inqubo yokusikwa futhi uqinisekise ukuthi ubuso bubushelelezi ngaphandle kokulimaza.
Ukupholisha ngokucindezela okuqhubekayo: Esigabeni sokugcina sokupholisha, sebenzisa i-sandpaper yedayimane engu-3000-grit kanye ne-cerium oxide polishing paste. Le nhlanganisela idala ngempumelelo isiphetho esicwebezelayo kukristalu. Ukugcina ingcindezi engaguquki ngesikhathi sokupholisha kubalulekile ukuqinisekisa indawo ebushelelezi nekhanyayo.
Izinzuzo Zokulawula Amatshe Aqondile
Ukulawulwa okunembile kosayizi wesihlabathi ngesikhathi sokucubungula amatshe kungathuthukisa kakhulu umkhiqizo kanye nekhwalithi:
Khulisa isivuno: Ngokukhetha ngokucophelela nokuqeda utshani, ungandisa isivuno sakho ngo-15%-22%. Lokhu kusebenza kahle kubaluleke kakhulu ezindleleni zokuhweba lapho izindleko zezinto zokwakha kanye nokuphathwa kwemfucuza kubalulekile khona.
Amanani okusebenza kabusha ancishisiwe: Ukwenza izivivinyo ezincane ngaphambi kokusetshenziswa okugcwele kusiza ekunqumeni indlela efanele yokuhlukanisa isihlabathi kanye nendlela yokwelapha. Izibonelo zephrojekthi yobungcweti zikhombisile ukuthi le ndlela inganciphisa amazinga okusebenza kabusha abe ngaphansi kuka-3%, okusindisa isikhathi kanye nezinsizakusebenza.
Ekuphetheni
Ukukhetha usayizi wegrit yesandpaper efanele kubalulekile ekuqedeni itshe ngempumelelo. Ukuqonda igrit yesandpaper kanye nokusetshenziswa kwayo kusiza abaqeqi bamatshe ukuthi bakhethe igrit efanele kuzo zonke izigaba, kusukela ekugayeni okuqinile kuya ekupholisheni okuhle. Ukulandela lo mhlahlandlela wosayizi wegrit kuzoqinisekisa imiphumela emihle kakhulu yokuqeda itshe, kuqinisekiswe ukuthi igrit isezingeni eliphezulu ethuthukisa ubuhle nokuqina kwendawo yakho yamatshe. Kungakhathaliseki ukuthi usebenza ngemabula, igranite, noma itshe elenziwe ngobunjiniyela, ukukhetha usayizi wegrit yesandpaper efanele kuzoba nomthelela omkhulu emkhiqizweni wakho wokugcina.
