Kia mōhio: 1. Hei tauira, ka whakamahia te kōhatu pākeho hei tauira mā ngā raraunga o runga ake nei. 2. Ehara te kaikohi puehu pāhekoheko i te whirihoranga paerewa, ā, me whiriwhiri kia rite ki te hiahia.
He pai ngā mira huri o Guilin HongCheng mō te huri i ngā rauemi kohuke kore-whakarewa rerekē, he iti iho i te 7 te pakeke o te Mohs, ā, he iti iho i te 6% te makuku, ka taea te whakarite i te pai o te mahi i waenga i te 60-2500 mesh. Ngā rauemi e tika ana pērā i te māpere, te kōhatu, te konupūmā, te feldspar, te waro whakahohe, te barite, te fluorite, te gypsum, te uku, te kairoiti, te kaolin, te wollastonite, te raima tere, te konganuku manganese, te bentonite, te talc, te asbestos, te mika, te kirinker, te feldspar, te quartz, ngā uku, te bauxite, me ētahi atu. Tena koa whakapā mai ki a mātou mō ētahi atu kōrero.
He hanganga matū noa iho te mira huri, he iti noa te wāhi e pau ana i te papa. He pakari te pūnaha o ngā taputapu nā te mea ka taea e ia te whakarite i tētahi pūnaha whakaputa motuhake, katoa hoki mō te kuru rauemi mata, te kawe, te huri tae atu ki te kohikohi, te penapena me te tākai.
Ka taea te whirihora i te pūnaha taraiwa (tapahi takirua, tapahi kotahi me te whakaiti) me te pūnaha whakarōpū (kaiwhakarōpū me te tātari) kia rite ki te rauemi, ki te hiahia rānei o te kiritaki, kia pai ai te mahi.
I runga i te rauemi hei whirihora i te pūnaha paipa me te pupuhi, kia whakaitihia ai te ātete ki te hau me te pakaru o te paipa, kia nui ai te kaha.
I whakamahia te maitai matotoru kounga teitei hei hanga i ngā wāhanga nui, i whakamahia hoki he rauemi ātete-kakahu mahi teitei hei hanga i ngā wāhanga ātete-kakahu. He tino ātete-kakahu te taputapu, ā, he pono hoki te mahi.
I tutuki i te pūnaha hiko whakahaere pokapū te mahi kore tangata me te tiaki ngāwari.
Ka taea te whakamahi i te pūnaha whakaputa hau hei whakahaere i te hau e toe ana. Ka eke te pai o te tātari ki te 99.9%.
I hangaia, i hangaia hoki mō ngā tohunga
He mea nui te ātete kakahu o ngā taputapu mira roera Raymond. I te nuinga o te wā, he tokomaha te hunga e whakaaro ana ko te pakeke o te hua, ko te ngāwari ki te mau, nō reira, he maha ngā whare hanga mira e pānui ana kei roto i ā rātou whakarewanga he chromium, e 30% te nui, ā, ko te pakeke HRC e 63-65. Heoi, ko te horapa o te tohatoha, ko te tūponotanga ka puta he kōhao iti me he kapiti iti i te atanga i waenga i te matrix me ngā carbides, ā, ka nui ake te tūponotanga o te whati. Ā, ko te pakeke o te mea, ko te uaua ki te tapahi. Nō reira, ehara i te mea ngāwari te hanga mowhiti huri ātete kakahu me te pakari. Ko te mowhiti huri te nuinga o te wā e whakamahi ana i ngā momo rauemi e rua e whai ake nei.
65Mn (65 manganese): ka taea e tēnei rauemi te whakapai ake i te pakari o te mowhiti huri. He āhuatanga tōna o te pakeketanga teitei, te ātete pai ki te kakahu me te ātete pai ki te aukumetanga, e whakamahia ana i te nuinga o te wā i roto i te mara tukatuka paura e hiahia ana te hua ki te tango i te rino. Ka taea te whakapai ake i te ātete kakahu me te pakari mā te whakataurite me te whakamahana i te maimoatanga wera.
Mn13 (13 konupora): kua pai ake te pakari o te mowhiti huri i hangaia ki te Mn13 ki te 65Mn. Ka rongoatia ngā whakarewa o tēnei hua ki te pakari wai i muri i te ringihanga, he kaha ake te kaha kume, te pakeke, te kirihou me ngā āhuatanga kore-aukume o ngā whakarewa i muri i te whakapakeketanga wai, ka roa ake te pakari o te mowhiti huri. Ina pāngia e te pānga kino me te pēhanga kaha i te wā e oma ana, ka whakapakeketia te mata, ka hanga he martensite, ā, ka hanga he paparanga mata tino ātete ki te kakahu, ka mau tonu te pakari o te paparanga o roto, ahakoa ka kakahuria ki te mata tino angiangi, ka taea tonu e te roera huri te tu atu i ngā kawenga ru nui ake.
E hiahia ana mātou ki te taunaki atu i te tauira mira huri tino pai kia whiwhi ai koe i ngā hua huri e hiahiatia ana. Tena koa, me kī mai ki a mātou ēnei pātai:
1. Tō rauemi mata?
2. Te matotoru e hiahiatia ana (mata/μm)?
3. Te kaha e hiahiatia ana (t/h)?
