I-Alumina emnyama eFuseneyo, ifanelekile kumashishini amatsha amaninzi njengaMandla eNyukliya, ukuPhaphama, iiMveliso ze-3c, isinyithi esingenasici, iiCeramics eziKhethekileyo, iziMpahla eziNxibelelayo eziNgqongileyo, njl.

Ingcaciso emfutshane

I-alumina edityanisiweyo emnyama yikristale emnyama engwevu efunyenwe ekudityanisweni kwe-bauxite yentsimbi ephezulu okanye i-alumina ephezulu kwi-arc yombane. Amacandelo ayo aphambili yi-α- Al2O3 kunye ne-hercynite. Ibonakala ngobulukhuni obuphakathi, ukuqina okuqinileyo, ukuzilola kakuhle, ubushushu obuphantsi bokusila kunye nokungatshisi phezulu, iyenza ibe yeyona nto igqwesileyo yokumelana ne-abrasion.

Indlela yokucubungula: ukunyibilika

Kubandakanya ishishini

Ilungele amashishini amaninzi amatsha anje ngamandla enyukliya, ukuhamba ngenqwelomoya, iimveliso ze-3C, intsimbi engatyiwa, iiseramikhi ezikhethekileyo, izixhobo ezixhathisayo zokunxiba, njl.

Iimpawu zeMveliso

1.Ukusebenza okuphezulu
Amandla okusika anamandla kunye nokuzilola kakuhle ukuphucula ukusebenza kakuhle kokusika.

2.Ixabiso elingcono / umlinganiselo wokusebenza
Iindleko ziphantsi kakhulu kunezinye iibrasives(aggregate) ezinomsebenzi olinganayo.

3.Umgangatho ophezulu
Ubushushu obuncinane obuveliswe kumphezulu, kunzima ukutshisa amaqhekeza omsebenzi xa kusetyenzwa. Ubulukhuni obuphakathi kunye nokugqiba okugudileyo okuphezulu kuyafezekiswa ngombala omncinci womphezulu.

4.Imveliso eluhlaza
Ukusetyenziswa okubanzi kwenkunkuma, ukunyibilika kwecrystallization, akukho rhasi ziyingozi eziveliswe kwimveliso.

Usetyenziso

I-Resin Cutting Disc
Ukudibanisa i-30%-50% ye-alumina emnyama edityanisiweyo kwi-alumina emdaka edityanisiweyo inokwandisa ububukhali bediski kunye nokugqiba okugudileyo, lula ukuguga komphezulu, ukunciphisa iindleko zokusetyenziswa, kunye nokunyusa umlinganiselo wexabiso/umsebenzi.

Ukuhombisa iitafile zentsimbi engatyiwayo
Ukukhazimlisa itafile yensimbi engenasici kunye negrit ye-alumina emnyama edityanisiweyo kunye ne-micropowder inokufikelela umbala ofanayo kwaye kunzima ukutshisa umphezulu.

Umphezulu okwaziyo ukumelana nokutyibilika
Ukusetyenziswa kwesanti yecandelo lealumina elimnyama elidityanisiweyo njengeaggregates ukugalela indlela yokutyibilika engagugiyo, ibhulorho, umgangatho wokupaka awupheleli nje ekufezekiseni iimfuno zokwenyani kodwa unomlinganiselo wexabiso/umsebenzi ophezulu.

Ukuqhunyiswa kwesanti
Igrit ye-alumina edityanisiweyo emnyama isetyenziswa njengemithombo yeendaba eqhumayo ukutshabalalisa umphezulu, ukucocwa kwemibhobho, i-hull-rust kunye neJean ilaphu lokuqhunyiswa kwesanti.

Ibhanti ye-Abrasive kunye nevili le-flap
Umxube we-alumina emnyama kunye nemdaka edityanisiweyo unokwenziwa kwilaphu elirhabaxa kwaye emva koko uguqulwe ube libhanti elirhabaxa kunye nevili le-flap ukuze kufakwe ipolishi.

Ivili leFayibha
Igrit ye-alumina edityanisiweyo emnyama okanye i-micropowder ifanelekile kukwenziwa kwevili lefiber yokusila kunye nokupholisha.

Ukupholisha iwax
I-alumina encinci ye-alumina edityanisiweyo emnyama inokwenziwa kwakhona kwiintlobo ngeentlobo zeewaksi zokupholisha ukuze zilungiswe kakuhle.
