Pōro Ukume Korekore 13%-30% Alumina 1/8″ 1/4″ 3/8″ 1/2″ 3/4″ 1″, 1¼” 1½” 2″ Pōro Pāpāho Tautoko
Pōro Ukume Korekore 13%-30% Alumina 1/8″ 1/4″ 3/8″ 1/2″ 3/4″ 1″, 1¼” 1½” 2″ Pōro Pāpāho Tautoko
Ngā Pōro Uku (Pōrēhana) Kore e Mau hei kawe tautoko mō ngā whakakorikori, ngā mea mimiti, hei tātari ngota; hei whakakī i te taputapu tauhohenga, ka mahi rātou hei tohatoha i ngā matū me ngā mea whakamatao i roto i ngā ahumahi hinu me te matū; hei tinana huri mō ngā rauemi mira i roto i ngā mira pōro i te wā e huri ana, e whakaranu ana i ngā matū, ngā rongoā, ngā tae, e huri ana i ngā mata whakarewa, e huri ana i ngā rauemi mata kai i roto i te ahumahi kai. He tino iti te mimiti wai o ngā pōro (tūturu <0.1%), he ātete waikawa teitei (>99.6%), ā, he roa te ora ratonga i raro i ngā tikanga whakahaere. He mea hanga ngā pōro pōrēhana ki te porēhana silicate (alumina) mā te whakakī paura o te papatipu, te whakahāngai, te kume mā te waha, me ngā diameter mai i te 3 mm ki te 50 mm. Ka taea te hanga i ētahi atu momo hua uku i runga i tāu tono me te tohu i ngā raraunga hangarau e tika ana.
