Alumina y'umweru ifite Na2o nkeya, irashobora gukoreshwa mu bikoresho bishyushya, ibicanwa n'ibitera imbaraga

Ibisobanuro bigufi

Alumina y'umweru ivanze n'amazi ni amabuye y'agaciro akozwe mu buryo bwa sintetike kandi afite isuku nyinshi.

Ikorwa binyuze mu guhuza Bayer Alumina nziza cyane ya Bayer mu itanura ry’amashanyarazi ku bushyuhe burenga 2000˚C hanyuma inzira yo gukonjesha igenda buhoro buhoro.

Gugenzura neza ubuziranenge bw'ibikoresho fatizo n'ibipimo byo guhuza bitanga umusaruro mwiza kandi wera cyane.

Ifu ikonje irasenywa, isukurwamo imyanda ya rukuruzi mu byuma bitandukanya rukuruzi bikomeye kandi bigashyirwa mu byiciro bito kugira ngo bijyane n'ikoreshwa rya nyuma.

Ibikoresho by'ibanze n'uburyo bikorwamo

Alumina y'umweru ivanze n'amazi ni amabuye y'agaciro akozwe mu buryo bwa sintetike kandi afite isuku nyinshi.

Ikorwa binyuze mu guhuza Bayer Alumina nziza cyane ya Bayer mu itanura ry’amashanyarazi ku bushyuhe burenga 2000˚C hanyuma inzira yo gukonjesha igenda buhoro buhoro.

Gugenzura neza ubuziranenge bw'ibikoresho fatizo n'ibipimo byo guhuza bitanga umusaruro mwiza kandi wera cyane.

Ifu ikonje irasenywa, isukurwamo imyanda ya rukuruzi mu byuma bitandukanya rukuruzi bikomeye kandi bigashyirwa mu byiciro bito kugira ngo bijyane n'ikoreshwa rya nyuma.

Porogaramu

Imirongo yihariye ikora ibicuruzwa bikoreshwa mu bikorwa bitandukanye.

Alumina y'umweru irashya cyane, bityo ikoreshwa mu bikoresho bya Vitrified Bonded Abrasives aho igikorwa cyo gukata vuba kandi gikonje ari ngombwa, ndetse no mu gukora ibikoresho bya Alumina bifite isuku nyinshi. Izindi porogaramu zirimo gukoreshwa mu bikoresho bya Alumina bitwikiriwe, kuvura ubuso, amatafari ya Ceramic, amarangi arwanya gucika, amatafari yo ku buriri akozwe mu mazi no kwita ku ruhu / amenyo.
