I-Superfine alumina iyimpahla eluhlaza ebalulekile yezitsha zobumba ezisebenzayo.Superfine alumina powder xz-L20, usayizi wezinhlayiyana 100 nm, umbala omhlophe, 99% wokuqukethwe okuqinile.Ingangezwa kuma-resins asekelwe emanzini ahlukahlukene, ngaphakathi kwama-resin asekelwe kuwoyela, ama-solvents nama-rubber ezingeni lokuhlanganisa lika-3% -5%, elingathuthukisa kakhulu ubulukhuni bezinto kuze kufike ku-6-8H noma ngaphezulu.
I-Grain Q-A1203, enendawo yayo yamakhemikhali ephansi nokumelana nezinga lokushisa eliphezulu, ayiyona i-alumina eyomile ecushiwe, futhi ayinawo umsebenzi we-catalytic.Inokumelana nokushisa okuqinile, ukuhleleka okuhle, isigaba sekristalu esizinzile, ubulukhuni obuphezulu nokuzinza okuhle kwe-dimensional, futhi ingasetshenziswa kabanzi ekuqiniseni nasekuqiniseni amapulasitiki ahlukahlukene, irabha, izitsha zobumba, izinto eziphikisayo neminye imikhiqizo, ikakhulukazi ukuthuthukisa ukuminyana, ukuqeda, ukukhathala okushisayo nokubanda, ukuqina kokuqhekeka, ukumelana nokukhuphuka kwe-ceramics kanye nokumelana nokugqokwa kwezinto ze-polymer.
