Ukuba uya kupeyinta uzakufuna isandpaper. Ngokususa igrisi kunye nesanti kakuhle ngaphambili ukupeyinta, uqinisekisa ukunamathela ngokufanelekileyo phakathi kwepeyinti kunye ne-substrate.
Ngaba uyafuna ukwazi ukuba yeyiphi sandpaper oyifunayo kumsebenzi wakho wokupeyinta? ISandpaper liphepha elizaliswe ziinkozo zesanti.
Inani leenkozo zesanti ngesentimitha yesikwere libonisa ixabiso le-P lephepha lesanti. Okukhona iinkozo ezininzi nge-cm2 nganye, kokukhona linyuka inani.
Iintlobo zesanti eziqhelekileyo ezisetyenziselwa ukupeyinta ziyi-P40, i-P80, i-P100, i-P120, i-P180, i-P200, i-P220, i-P240, i-P320, i-P400. Okukhona lisezantsi inani, kokukhona lirhabaxa iphepha lesanti. I-Sandpaper iza kwiimilo ezininzi kunye nobukhulu. I-sandpaper ingasetyenziswa zombini ngesandla kunye noomatshini. Ukuthengwa ngexesha elinye kwe-sander kunokukusindisa umsebenzi omninzi.

Thenga i-sandpaper erhabaxa
Ufuna sandpaper erhabaxa xa ukususa umhlwa kunye nee layers zepeyinti ezindala. I-P40 kunye ne-p80 zirhabaxa kangangokuba ungayisusa lula ipeyinti endala, ubumdaka kunye ne-oxidation ngeentshukumo ezimbalwa zesanti. I-sandpaper erhabaxa iyimfuneko kuye wonke umzobi kwaye kufuneka yongeza kwingqokelela yakho yezixhobo zokupeyinta. Xa usebenzisa i-sandpaper erhabaxa kumsebenzi orhabaxa, wonga ixesha elininzi kunye nesanti ecolekileyo evaleka ngokukhawuleza. Emva kokusebenzisa i-sandpaper erhabaxa, kufuneka uqale utshintshele kwigrit ephakathi/ecolekileyo. Kungenjalo uya kubona imikrwelo kumsebenzi wakho wokupeyinta.
Igrit ephakathi
Phakathi kwegrit erhabaxa kunye necolekileyo ukwanalo nephepha elirhabaxa eliphakathi. Ngegrit emalunga ne-150 ungasusa imikrwelo enzulu kwisanti erhabaxa kwaye emva koko uyisantile ngegrit ecolekileyo. Ngokurhweba ngesanti ukusuka kwi-coarse, medium to fine, ufumana umphezulu olinganayo ngokugqibeleleyo kwaye ke isiphelo esimtyibilizi.
I-sandpaper entle
I-sandpaper entle ineyona grit kwaye ke yenza eyona mikrwelo inzulu kakhulu. I-sandpaper efanelekileyo kufuneka isetyenziswe ekugqibeleni, kodwa unokuyisebenzisa ngokuthe ngqo kwindawo epeyintiweyo ngaphambili. Umzekelo, ukuba uya kupeyinta umnyango ongekabonakali kwipeyinti, unokwenza isanti kuphela nge-sandpaper ecocekileyo emva kokunciphisa. Oku ke kwanele ukuqalisa ukupeyinta. Kwakhona kwiplastiki usebenzisa ingqolowa ecolekileyo kuphela ukuthintela imikrwelo. Ngoko uhlala ugqiba ngengqolowa ecolekileyo xa usantiya. Hlala ucocekile emva kwesanti ngaphambi kokupeyinta. Ewe awufuni uthuli kwipeyinti yakho.
I-Advanteji ye-sandpaper engangenwa ngamanzi
Ukusantiya okungangeni manzi kunokuba sisisombululo. I-sandpaper yesiqhelo ayixhathisi amanzi. Ukuba usebenzisa i-sandpaper engangeni manzi, ungasanti ngaphandle kothuli. I-sandpaper engenamanzi inokuba sisisombululo ukuba kufuneka usebenze kwindawo emanzi.
Ukuhlamba nge-scotch brite
Ukongeza kwi-sandpaper engenamanzi, wena iyakwazi kwakhona isanti emanzi kwaye ayinathuli nge "scotch brite". I-Scotch brite ayilophepha kodwa luhlobo "lwephedi" onokuthi uyithelekise nenxalenye yesanti eluhlaza kwipadi yokukhuhla. Xa usenza isanti nge-scotch brite, kububulumko ukwenza oku ngokudibanisa nepeyinti yokucoca, i-degreaser okanye isicoci esifanelekileyo senjongo yonke (esingashiyi nayiphi na imikhondo) .Ngesanti emanzi kunye ne-degreaser kunye ne-scotch brite uyayenza. Akufuneki ukuba udilize kuqala kwaye emva koko udibanise, kodwa unokwenza zombini ngexesha elinye, ulingise emva kwesanti kwaye ulungele ukupeyinta.
Ngaba unayo nayiphi na imibuzo malunga neli nqaku okanye ungathanda ingcebiso yomntu kumzobi?
Ungandibuza umbuzo apha.
Ithamsanqa kwaye wonwabe ukupeyinta!
