Ukupholisha amatshe kuyinqubo ecophelelayo edinga ukukhethwa ngokucophelela kwephepha lesihlabathi elifanele noma iphedi yokubhula. Usayizi wamatshe uthinta ngqo ukuphela kokugcina kobuso betshe, ngakho-ke usayizi wamatshe afanele kumele ukhethwe ngokusekelwe ebulukhunini betshe kanye nomphumela wokupholisha ofiselekayo. Lesi sihloko sizohlola ubudlelwano phakathi kosayizi wamatshe esihlabathi kanye nemiphumela yokupholisha, futhi sinikeze isiqondiso sokukhetha usayizi wamatshe afanele ezinhlobo ezahlukene zamatshe.
Ubudlelwano Phakathi Kobukhulu Be-Sandpaper Grit kanye Nomphumela Wokupholisha
Usayizi we-grit we-sandpaper ubhekisela enanini lezinhlayiya ezirhabaxa nge-intshi yesikwele se-sandpaper. Lokhu kulinganisa kunquma ubulukhuni noma ukuqina kwe-sandpaper:
Utshani obuncane (80-120): Utshani obuqinile busetshenziselwa ukupholisha kokuqala nokususa amabala noma imihuzuko ejulile ebusweni betshe. Lawa ma-grit akhiqiza imihuzuko emikhulu futhi afaneleka ekugayweni nasekubunjweni kwetshe kokuqala.
I-grit ephezulu (600-1000 grit nangaphezulu): I-grit encane ikhiqiza imihuzuko emincane, okuholela endaweni ecolekile necwebezelayo. Iphepha le-sandpaper elicwebezelayo lisetshenziswa ezigabeni zokugcina zokupholisha, lapho umgomo uwukuthola indawo ebushelelezi necwebezelayo.
Isihluthulelo sokupholisha ngempumelelo ukwandisa kancane kancane usayizi wegrit ngesikhathi senqubo yokupholisha. Ukuqala ngosayizi wegrit ophansi kungasusa ukungapheleli, kanti ukushintshela kancane kancane kosayizi wegrit ophakeme kungalungisa ubuso futhi kuthuthukise ukukhanya.
Khetha i-Grit Efanele Ngokusekelwe Kubulukhuni Betshe
Ubulukhuni betshe budlala indima ebalulekile ekunqumeni usayizi ofanele wokugaya okupholisha:
Amatshe athambile (isb. itshe lensipho, itshe le-limestone):
I-Grit Yesihlabathi Enconyiwe: Ukuze kupholishwe okokuqala, kunconywa ukusebenzisa i-sandpaper ene-grit ephansi, njenge-grit engu-80-120. Amatshe athambile kulula ukuwagaya nokuwapholisha, ngakho-ke i-grit sandpaper eqinile ingasetshenziswa ukufeza imiphumela eyanelisayo.
Inqubo: Ngemva kokususa amabala ajulile, kancane kancane sebenzisa ama-grit aphezulu (afinyelela ku-grit angu-600) ukuze uthole indawo ebushelelezi.
Itshe eliqinile eliphakathi nendawo (isib. imabula, i-travertine):
I-Sandpaper Grit Enconyiwe: Ukuze kupholishwe okokuqala, sincoma ukusebenzisa i-sandpaper cishe ngama-grit angu-120-220. Lokhu kuzosiza ukususa ukungapheleli kobuso ngenkathi kuthambile ngokwanele ukuthi kungalimazi itshe.
Inqubo: Esigabeni sokugcina sokupholisha, sebenzisa ama-grit acwebezelayo (afinyelela ku-1000 grit) ukuze uthole ukuqeda okucwebezelayo okuphezulu.
Itshe eliqinile (isib. i-granite, i-quartz):
I-Grit Enconywayo: Uma unamatshe aqinile, qala ngosayizi we-grit ophakeme, njenge-grit engu-220-400, ukuze ugweme ukuguguleka ngokweqile kwe-sandpaper futhi upholishe kahle indawo.
Inqubo: Ukushintshela ku-grit encane (kufika ku-grit engu-3000 noma ngaphezulu) ukuze kupholishwe okokugcina ukuze kufezwe ukuqeda okufana nesibuko.
Uhla Lwe-Sandpaper Grit Olunconyiwe
Ukupholisha kwangaphambi kwesikhathi:
Ezinhlotsheni eziningi zamatshe, i-sandpaper engu-80-120 grit ilungele ukupholishwa kokuqala. Le grit isusa ngempumelelo izindawo ezikrwada, imihuzuko, kanye namaphutha abonakalayo, ibeka isisekelo esiqinile sokupholishwa okuhle okulandelayo. I-grit eqinile iyasiza ekwakheni itshe ngokushesha, ilungiselele ukupholishwa okulandelayo ngama-grit acwebezelayo.
Ukupholisha kahle:
Uma ubuso betshe bubushelelezi, kufanele ukhuphule kancane kancane ucezu lwephepha lesihlabathi ukuze upholishe kahle. Ngokuvamile, kunconywa ukusebenzisa iphepha lesihlabathi lesihlabathi elingu-600-1000 ukuze uthole ukukhanya okucwebezelayo. Leli cwebe lisiza ekucwebezeliseni indawo futhi lithuthukise ukukhanya kwayo.
Uma kudingeka ukuqeda okuncane, sebenzisa i-grit paper ephezulu, njenge-grit engu-1500 noma ngaphezulu. Lawa ma-grit sandpaper amahle kakhulu alungele ukudala ukuqeda okukhazimulayo, ikakhulukazi ekusetshenzisweni kokuhlobisa okuphezulu.
Amanothi Ngokupholisha
Ngaphezu kokukhetha i-grit sandpaper efanele, kufanele kuthathwe izinyathelo eziningana zokuqapha ukuqinisekisa ukuthi ipholisha kahle:
Gcina indawo ihlanzekile: Ngaphambi kokuthi uqale ukupholisha, qiniseka ukuthi i-sandpaper kanye nendawo yamatshe kuhlanzekile. Ukungcola kungabangela imihuzuko futhi kuthinte kabi umphumela wokugcina.
Sebenzisa amanzi noma uketshezi lokupholisha: Ukwengeza amanzi noma uketshezi lokupholisha enkambisweni yokupholisha kusiza ukunciphisa ukushisa okungqubuzanayo phakathi kwephepha lesihlabathi netshe. Lokhu akugcini nje ngokuvimbela itshe ekushiseni ngokweqile, kodwa futhi kuthuthukisa umphumela wokupholisha ngokuligcoba.
Khulisa kancane kancane usayizi wegrit we-sandpaper: Ngesikhathi senqubo yokupholisha, kubalulekile ukwandisa kancane kancane usayizi wegrit we-sandpaper. Ukungabi nosayizi wegrit kuzoholela ekupholiseni okungalingani futhi kungadinga umsebenzi owengeziwe ukuze kulungiswe. Ukushintsha okubushelelezi kusuka ekupholiseni okuqinile kuya ekupholiseni okucolekile kuzoqinisekisa ukuthi ukupholisha kuyafana.
Qapha ingcindezi: Uma upholisha, faka ingcindezi engaguquki nephakathi. Ingcindezi enkulu izobangela ukuguguleka okungalingani kwephepha lesihlabathi futhi ingalimaza ubuso betshe.
Ekuphetheni
Ukukhetha okulungileiphepha lokusantaUsayizi wegrit uyisinyathelo esibalulekile enkambisweni yokupholisha itshe. Ukuqonda ububanzi begrit obunconywayo kokubili ukupholisha kokuqala nokokugcina, kanye nokuthatha izinyathelo zokuphepha ezidingekayo, kuzoqinisekisa imiphumela emihle kakhulu. Kungakhathaliseki ukuthi usebenza ngezinto ezithambile noma eziqinile, ukukhetha usayizi wegrit ofanele ngokusekelwe ebulukhunini betshe kanye nokuphela okufiswayo kuzoqinisekisa indawo enhle epholishiwe. Ngokunaka imininingwane kanye nobuchwepheshe obufanele, ungathuthukisa ubuhle bemvelo betshe futhi ufinyelele ukupholisha kwekhwalithi yobungcweti.
