Isihlabathi se-corundum emhlophe, i-corundum powder emhlophe, i-corundum ensundu kanye nezinye iziqhumane ziyi-abrasives evamile, ikakhulukazi i-white corundum powder, okuyiyona ndlela yokuqala yokukhetha ukupholisha nokugaya.Inezici zekristalu eyodwa, ubulukhuni obuphezulu, ukuzilola okuhle, nokusebenza kokugaya nokupholisha.Izinzuzo ezifana nokuphakama ziye zasetshenziswa futhi zakhuthazwa ezimbonini ezihlukahlukene.Ngakho-ke, ungakhetha kanjani lapho upholisha?
Ukukhetha abrasive
I-Abrasive umzimba oyinhloko odlala indima yokusika enqubweni yokugaya.Ibhekene ngqo nomsebenzi wokusika futhi iyisici esiyisisekelo sesondo lokugaya ukuze likhiqize umphumela wokugaya.I-abrasive kufanele ibe yi-corundum ensundu ekhiqizwe i-Xinli engagugi.Imikhiqizo yayo inobulukhuni obuphezulu, ukumelana nokushisa, ukuzinza kokushisa kanye nokuzinza kwamakhemikhali, futhi kufanele ibe nokuqina okuthile ukuze ikwazi ukumelana namandla athile okugaya.
Umgomo wokukhetha ohlukumezayo
Uma ugaya izinto eziqinile eziqinile, sebenzisa ama-abrasive e-corundum anokuqina okuphezulu.Izinto zokugaya ezinamandla aphansi aqinile ukuze ukhethe ama-brittle silicon carbide abrasives.
Ukwengeza ekucabangeni amandla aqinile we-workpiece material, ubulukhuni be-workpiece material futhi isisekelo esiyinhloko sokukhetha lapho ukhetha ama-abrasives.Ngokuvamile, ubulukhuni be-abrasive kufanele buphindwe izikhathi ezingu-2-4 kunobulukhuni bempahla yokusebenza.Uma kungenjalo, izinhlamvu ezihlabayo ezinobunzima obuphansi zizodlula ngokushesha ngesikhathi sokusika ngesivinini esikhulu futhi zilahlekelwe ikhono lokusika, okuzokwenza ukuqina kwesondo kube phansi kakhulu futhi kuthinte ukusika.ukusebenza kahle, kanye nekhwalithi yokucubungula ayikwazi ukuqinisekiswa.Ngakho-ke, ukuphakama kokuqina kwempahla yokusebenza, kufanele kube bukhuni obuqinile be-abrasive.
Ukukhethwa kwezakhiwo ezilimazayo
Kufanele futhi kucatshangelwe ukusabela okungenzeka kwamakhemikhali ohlelweni lwenqubo yokugaya.Endaweni yokuxhumana yokugaya, ama-abrasives, ama-binders, izinto zokusebenza, uketshezi lokugaya kanye nomoya kujwayele ukusabela okuzenzakalelayo kwamakhemikhali ngaphansi kwesenzo se-catalytic sokushisa kokugaya namandla okugaya.Uma kusetshenziswa insimbi, ukugqokwa kwe-abrasive kuyashesha kunaleyo ye-corundum abrasive lapho kugaywa insimbi.Isizathu esiyinhloko salokhu ukusabela kwamakhemikhali okunamandla phakathi kwe-silicon carbide abrasive nensimbi.
Ukwengeza, ukuzinza kokushisa kwe-abrasive kufanele futhi kucatshangelwe lapho kukhethwa i-abrasive.Lapho ugaya ezinye izinto okunzima ukuzigaya, ezinye izingozi zenzeka lapho indawo yokugaya ijwayele ukukhiqiza amazinga okushisa aphezulu.
