Izinhlobo zamabhande e-sanding afanele amapuleti okugaya nokupholisha
Ukukhetha ibhande le-abrasive ngendlela efanele futhi ngokunengqondo akukhona nje kuphela ukuthola ukusebenza kahle kokugaya, kodwa futhi ukucabangela impilo yesevisi yebhande le-abrasive.Isisekelo esiyinhloko sokukhetha ibhande le-abrasive yizimo zokugaya, njengezici ze-workpiece yokugaya, isimo somshini wokugaya, ukusebenza kanye nezidingo zobuchwepheshe ze-workpiece, kanye nokusebenza kahle kokukhiqiza;ngakolunye uhlangothi, iphinde ikhethwe ezicini zebhande eliqhumayo.
Izici:
I-silicon carbide abrasives, indwangu ehlanganisiwe, isihlabathi sokutshala esiminyene, inomsebenzi wokumelana kwamanzi namafutha.Ingasetshenziswa kokubili eyomile futhi emanzi, futhi isipholile singengezwa.Ifanele ukucaciswa okuhlukahlukene kwamabhande e-sanding.
Isetshenziswa kakhulu ku:
Zonke izinhlobo zokhuni, ipuleti, ithusi, insimbi, i-aluminium, ingilazi, itshe, ibhodi lesifunda, i-copper clad laminate, i-faucet, i-hardware encane nezinsimbi ezihlukahlukene ezithambile.
Okusanhlamvu okusanhlamvu: 60 # -600 #
I-Silicon carbide (SiC) yenziwe ngesihlabathi se-quartz, i-petroleum coke (noma i-coke yamalahle), kanye nama-chips ezinkuni ngokusebenzisa izinga lokushisa eliphezulu lokuncibilika esithandweni sokumelana.
Kubandakanya i-silicon carbide emnyama ne-silicon carbide eluhlaza:
I-silicon carbide emnyama yenziwe ngesihlabathi se-quartz, i-petroleum coke kanye ne-silica yekhwalithi ephezulu njengezinto zokusetshenziswa eziyinhloko, futhi inyibilikiswa ekushiseni okuphezulu esithandweni sokumelana.Ukuqina kwayo kuphakathi kwe-corundum nedayimane, amandla ayo okusebenza aphakeme kune-corundum, futhi i-brittle futhi ibukhali.
I-silicon carbide eluhlaza yenziwe nge-petroleum coke kanye ne-silica yekhwalithi ephezulu njengezinto zokusetshenziswa eziyinhloko, ingeza usawoti njengesengezo, futhi inyibilika ekushiseni okuphezulu esithandweni sokumelana.Ukuqina kwayo kuphakathi kwe-corundum nedayimane, futhi amandla ayo omshini aphakeme kunalawo e-corundum.
Ama-abrasive e-silicon carbide asetshenziswa kakhulu anamakristalu amabili ahlukene:
Enye i-silicon carbide eluhlaza, equkethe ngaphezu kuka-97% SiC, esetshenziselwa kakhulu ukugaya amathuluzi aqinile anegolide.
Enye i-silicon carbide emnyama, enokukhanya kwensimbi futhi iqukethe i-SiC engaphezu kuka-95%.Inamandla amakhulu kune-silicon carbide eluhlaza kodwa ubulukhuni obuphansi.Isetshenziselwa ikakhulukazi ukugaya insimbi ekhonjiwe kanye nezinto ezingezona ezensimbi.Ukuthungwa kwe-silicon carbide emnyama i-brittle futhi ilukhuni kune-corundum abrasives, futhi ukuqina kwayo kungaphansi kune-corundum abrasives.Okwezinto zokwakha ezinamandla aphansi aqinile, njengezinto ezingezona ezensimbi (amapuleti ahlukahlukene njenge-plywood yokhuni, i-particleboard, i-high, medium and low density fiberboard , ibhodi loqalo, ibhodi le-calcium silicate, isikhumba, ingilazi, izitsha zobumba, itshe, njll.) kanye izinsimbi ezingenayo insimbi (i-aluminium, ithusi, umthofu, njll.) nezinye izinto ezifanele kakhulu ukucubungula.Futhi iyi-abrasive efanelekile yokucubungula izinto eziqinile neziphukayo.
