I roto i ngā mahi huri tika, ko te mahi a te wira huri ka whakatauhia e te kounga me te pumau o ōna kirikiri whakakoi. I te mea e hiahia ana ngā kaiwhakamahi mutunga i roto i te hanga motuka, rererangi, me ngā taputapu ki ngā manawanui pakari ake me te kounga teitei ake o te mata, kei te anga atu ngā kaihanga wira huri ki ngā wero e pā ana ki te kino wera, te kakahu o te wira, me te koretake o te tukanga. I raro i ēnei āhuatanga, ko te whiriwhiri i te rauemi whakakoi ka noho hei mea whakatau i roto i te mahi hua me te whai huatanga o te whakaputa.
Ko te alumina whatu mā (WFA), he momo konumohe waikura tino parakore, i hangaia kia tutuki ai ngā whakaritenga pakari o ngā mahi hurihanga teitei. Me te nui o te Al₂O₃ e neke atu ana i te 99%, he hanganga tioata ōrite te WFA me te pakeke teitei (Mohs 9.0), e whakarite ana i te whanonga tapahi pumau i raro i ngā āhuatanga kawenga teitei. Ki te whakatauritea ki ngā mea whakakoi tikanga, ko tōna ngawari whakahaere ka taea te matapae i te pakaru moroiti, e whakaatu tonu ana i ngā taha tapahi hou, ā, e pupuri ana i te koi o te wira puta noa i te huringa hurihanga.
Ko tētahi o ngā take matua o te huri i ngā maitai me ngā rauemi koranu kua whakapakeketia ko te whakaputanga wera nui, e arahi ana ki te wera o ngā mea mahi, te kino o te mahi whakarewa, me te whakaiti i te roa o te ora o te ngenge. Ka whakaitihia e te WFA tēnei raruraru mā roto i tana tikanga whakakoi-ake me te iti o te ātete huri, e whakaiti ana i te waku i te atanga pa. Ko te hua o tēnei he iti ake ngā pāmahana huri, he pai ake te mutunga o te mata, me te whakapai ake i te pumau o ngā āhuatanga—he tawhā nui mō ngā wāhanga tino tika.
Mai i te tirohanga hangahanga, he mea nui te ōritetanga o te tohatoha rahi o te witi whakakoi me te hanganga matū hei whakarite i te ōritetanga o ngā wira huri i ia puranga. Ko te rerekētanga o ngā rauemi mata ka arahi i te whanonga wira kore pumau, te pikinga o te auau whakakakahu, me te teitei ake o ngā reiti whakakorenga. Ko te WFA kounga teitei, i hangaia i raro i ngā tukanga whakarewa me te whakarōpūtanga whakahaere, ka tukuna he manawanui rahi matūriki kikī (ngā paerewa FEPA) me te iti o ngā poke, ka taea ai e ngā kaihanga te whakatutuki i te mahi tāruarua puta noa i ngā oma whakaputa.
Haunga ngā painga o te mahi, ka whai wāhi te WFA ki te roa o te ora o te wira me te whakapai ake i te whai huatanga o te utu. Ko tōna pakari taurite me te ngawari o te pakarukaru ka whakaiti i te maturuturunga wawe o te witi, me te aukati i te karaihe, ā, ka pai ake te tere o te pakaru o te wira huri. Ko te tikanga o tēnei he iti ake te whakawhiti wira, he iti ake te wā kore mahi, ā, he pai ake te hua whānui mō ngā kaiwhakamahi mutunga.
I XINLI Abrasive, ka arotahi mātou ki te tuku i te alumina ma kua whakakīia ki te matotoru, he rite tonu te whakaritenga, he mea hanga mō te hanga wira huri. Ka whakarite tā mātou pūnaha whakaputa i te hanganga matū pumau, te whakahaere tika i te rahi o te matūriki, me te tuku pono i te nuinga, hei tautoko i ngā kaihanga ki te hanga taputapu whakakī teitei mō ngā tono ahumahi uaua.
I te haere tonu o te ahumahi ki te neke ki te tika me te whai huatanga, ka nui haere te hiranga o ngā rauemi whakakoi matatau. Ehara i te mea he whakatau hangarau noa iho te whiriwhiri i te alumina ma kua whakaranua, engari he taahiraa rautaki ki te whakapai ake i te kounga o te hua, te whakaiti i te rerekētanga o ngā tukanga, me te whakapakari i te whakataetae mākete.
