Amathuluzi wokupholisha ukhonkolo ikakhulukazi ahlanganisa lokhu okulandelayo:
Ama-PCD okukhipha ama-coating discs, asetshenziselwa ukususa okokunamathela esitezi esikhonkolo, ayadingeka uma kukhona okujiyile okufana ne-epoxy phansi.
Amadiski okugaya idayimane, ngokuvamile asetshenziselwa ukulinganisa phansi kukakhonkolo nokulungiswa kabusha kwaphansi okudala.
Amaphedi okupholisha idayimane awugqinsi, ngokuvamile abhekisela kumaphedi wokupholisha we-resin bond anogqinsi oluyi-5mm noma ngaphezulu, asetshenziselwa ukulinganisa phansi kukakhonkolo, ukugaya nokupholisha.
Iphedi lokupholisha idayimane elizacile, ngokuvamile libhekisela kumaphedi wokupholisha webhondi ye-resin anogqinsi olungaphansi kuka-5mm, asetshenziselwa ukupholisha kahle.
Amaphedi wokupholisha isipontshi, ngokuvamile asebenzisa i-fiber eyenziwe ngumuntu, uvolo noma ezinye izinwele zezilwane njengesisekelo/isekelo kanye namadayimane nama-abrasive afuthwe futhi acwiliswe ngaphakathi kwesisekelo.
Kunezinhlobo eziningi zamathuluzi okupholisha okupholisha phansi okukhonkolo, ukuthi ungakhetha kanjani futhi uwasebenzise kanjani?
Ukuze sikhethe futhi sisebenzise amathuluzi okupholisha ngendlela efanele, kufanele siqale siqonde amabizo alandelayo:
Ukucaba kwephansi
Ezitezi ezinyathelwe phansi noma ezilinganiswe ngesandla noma ezidala ezixegayo futhi ezilimele kakhulu, kuyadingeka ukulinganisa noma ukususa ungqimba olungaphezulu oluxekethile.Kudingeka sisebenzise igrinder yamandla aphezulu kanye namadiski okugaya idayimane anolaka ukuze ileveli iphansi ngaphambi kokupholisha.Ngezitezi ezizilinganisa ngokwazo noma izitezi ezilinganiswe ngemishini yokudonsa amandla, singathola iphansi elihle elipholishiwe elinamaphedi okupholisha amabhondi e-resin kuphela.
Ukuqina kwephansi
Usimende osetshenziselwa ukuthela phansi ukhonkolo umelwe inombolo, efana no-C20, C25, C30 njll. esivame ukukhuluma ngayo.Ngaphansi kwezimo ezijwayelekile, inani eliphakeme liba lukhuni ukhonkolo, kodwa ngenxa yezici ezihlukahlukene, inani likasimende nokuqina kwephansi ngokuvamile akuhambisani.Ukuqina kokhonkolo phansi kuvame ukuvezwa ubulukhuni be-Mohs.Ubulukhuni be-Mohs bephansi likakhonkolo ngokuvamile buphakathi kuka-3 no-5. Esizeni somsebenzi wokwakha, singasebenzisa ezinye izinto esikhundleni sokuhlola ubulukhuni be-Mohs ukuze sazi ubulukhuni bephansi.Uma singathola amazinyo noma imihuzuko phansi ngezinzipho zensimbi noma okhiye singasho ukuthi ubulukhuni bekhonkrithi bungaphansi kuka-5, ngaphandle kwalokho, ubulukhuni bungaphezu kuka-5.
Ikhwalithi nesivinini se-grinder
Imishini yokugaya phansi ngokuvamile ihlukaniswa ngesisindo esilula, usayizi ophakathi kanye nezinsimbi ezisindayo.Izigayi ze-heavy duty zinamandla aphezulu ngakho ukusebenza kahle okuphezulu.Kuzinhlelo zokusebenza zangempela, uma kuziwa kuma-grinders, akuyona enkulu engcono.Nakuba ukusebenza kahle kokugaya kwama-heavy duty grinders kuphezulu, futhi kungenzeka ukuthi kuholele ekugayeni ngokweqile ngakho-ke kwenyusa izindleko zokwakha.Osonkontileka abanolwazi bazolungisa isivinini esijikelezayo, isivinini sokuhamba, inombolo yamadiski okugaya kanye nesisindo somshini ukuze kuncishiswe izindleko zokwakha futhi kuthuthukiswe ukusebenza kahle kokwakhiwa.
Uhlobo nosayizi wamathuluzi okupholisha
Amathuluzi asetshenziswa kakhulu okupholisha phansi kukakhonkolo amadiski okugaya e-PCD, amadiski okugaya ibhondi yensimbi namaphedi okupholisha ibhondi ye-resin.Amadiski okugaya e-PCD asetshenziselwa ukususa izinto eziwugqinsi endaweni ephansi, amadiski okugaya ibhondi yensimbi asetshenziselwa ukulungisa indawo yaphansi kanye nokugaya okumahhadlahhadla, amaphedi okupholisha ibhondi yeresin asetshenziselwa ukugaya nokupholisha.Inombolo yegrit yamathuluzi okupholisha isho usayizi wezinhlayiya zedayimane eziqukethwe kumathuluzi.Lapho inombolo yegrit iphansi, isayizi yezinhlayiyana zedayimane inkulu.Ayikho inombolo yegrit yamadiski okugaya e-PCD, kodwa anesiqondiso, ngokwewashi nangokuphikisana newashi.Kudingeka sinake isiqondiso sayo lapho sisebenzisa i-PCD.Metal bond ukugaya discs ngokuvamile iza grits 30#, 50#, 100#, 200#, 400#.Ngokuvamile sinquma ukuthi iyiphi inhlanzi okufanele iqale ngokuvumelana nezimo zaphansi.Isibonelo, uma izinga lephansi lingelihle noma indawo engaphezulu ixega ngokuqhathaniswa, kungase kudingeke ukuthi siqale ngamadiski okugaya ibhondi yensimbi engu-30# ukuze sisuse indawo evulekile futhi ileveli phansi.Uma sifuna ukuveza izilinganiso, 50# noma 100# amadiski okugaya ibhondi yensimbi ayadingeka.Amaphedi okupholisha ibhondi ye-resin eza namagrits asuka ku-50# kuya ku-3000#, amagridi ahlukene ahlukaniswa ngombala we-Velcro ohlukile.Kunamaphedi okupholisha aminyene namaphedi okupholisha amancane.Amaphedi okupholisha aqinile aqinile afanele usayizi omaphakathi kanye nezigayi ezisindayo.Amaphedi okupholisha azacile ayavumelana nezimo ezifanele izigayi ezinesisindo esincane ukuze zipholishwe kahle.
Uma uqonda izinto ezingenhla ezi-4 ezithinta ukukhetha kwethu amaphedi wokupholisha.Ngikholwa ukuthi usuyazi ukuthi ungakhetha kanjani amathuluzi okupholisha afanele ohlelo lwakho lokusebenza lokupholisha phansi kukakhonkolo.
