I roto i te ao o ngā rauemi ātete-wai, kua noho te korundum hei rauemi mata nui, hei rauemi whānui e whakamahia ana i roto i te umanga ātete-wai nā ōna āhuatanga ā-tinana me ā-matū pai rawa atu. Ka whakamāramahia e tēnei tuhinga ngā āhuatanga taketake, ngā tono whānui, te tūnga mākete, me te tukanga whakaputa o te korundum, ā, ka arotahi ki te mīhini huri korundum 200-mata teitei hei whakaatu ki a koe me pēhea te ārahi i tētahi wā hou o te huri pai.

He kōhatu te kōrundum i hangaia mā te whakatiotanga o te waikura konumohe. Ko tōna pakeke te tuarua o te taimana me te nitride boron cubic, ā, e 9 te pakeke o te Mohs. Nō Īnia te ingoa o te kōrundum. Ko tōna wāhanga matua ko te Al₂O₃, ā, e toru ngā momo: α-Al₂O₃、β-Al₂O₃、γ-Al₂O₃. Nā ōna āhuatanga ā-tinana tino pai, e whakamahia whānuitia ana te kōrundum i roto i ngā rauemi huri matatau, ngā wati, ngā rauemi peera mō ngā mīhini tika, me ētahi atu mara.

Te whakamahinga o te kōrundum

He whānui rawa te whānuitanga o te whakamahinga o te kōrundum, e kapi ana i ngā mara ahumahi maha pēnei i te whakarewa, te mīhini, te ahumahi matū, te hikohiko, te rererangi, me te tiaki whenua. Nā tōna ātete ki te pāmahana teitei, te ātete ki te waikura, me te kaha teitei, ka whakamahia te kōrundum hei oko me te ipu mō te whakarewa i ngā tatau reti maitai, te whakarewa i ngā konganuku utu nui onge, me ngā koranu motuhake; i roto i ngā pūnaha matū, ka whakamahia te kōrundum hei ipu tauhohenga me ngā paipa me ngā wāhanga papu matū; i roto i te mara miihini, ka whakamahia te kōrundum hei hanga maripi, pokepokea ai, rauemi ātete matā, me ētahi atu. Hei tāpiri, ka taea hoki te whakamahi i ngā hua kōrundum mārama hei hanga rama me ngā matapihi ngaruiti, ā, ko ngā hua Na-b-Al₂O₃ he rauemi electrolyte mō te hanga pākahiko konutai-whanariki.

Te Āhua o te Mākete Korunuma

I ngā tau tata nei, me te whanaketanga o te pūtaiao me te hangarau me te tere o te whanaketanga o te ahumahi, kua piki haere tonu te hiahia mō te kōrundum, ā, he whānui ngā tūmanakohanga mākete. Ko Haina, ko Īnia, me Brazil ngā kaihanga kōrundum nui o te ao, ā, ko Haina te kaihanga me te kaweake nui rawa atu o te kōrundum mā. He taurite te mākete kōrundum i waenga i te tuku me te tono, me te whakapai tonu i te kounga o te hua me te whānui haere o ngā wāhi tono. Ina koa i roto i ngā mara teitei pēnei i te huri me te oro tino tika, kei te whānui haere te tono o te kōrundum.

Te tukanga whakaputa o te korundum

He maha ngā mahi o te tukanga whakaputa korunamu pērā i te whakarite rauemi, te whakarewa, te whakamatao, te whakatioata me te tukatuka. Tuatahi, ka tirotirohia te paura konumohe waikura tino parakore, ka whakamarokehia kia rite ai te āhua me te parakore o ngā rauemi mata. Kātahi ka whakanohoia te paura konumohe waikura ki roto i te oumu hiko, ka whakamahanatia ki te pāmahana teitei kia rewa ai hei wai. I te āhua rewa, ka whakarite anō ngā ngota konumohe waikura kia hanga he hanganga tioata, kia hanga hoki he matūriki korunamu. Kātahi ka whakahekehia mārire te pāmahana kia mārō haere ngā matūriki korunamu hei totoka. Hei whakamutunga, ka whakamahanatia anō kia pumau ake ai te hanganga tioata, kia pai ake ai te pakeke me te ātete ki te kakahu o te korunamu.

Whakataki o te mīhini huri pai rawa atu o te corundum 200 mesh

Ina whakamahia te korundum i roto i ētahi mara, me huri tuatahi kia puta he paura angiangi 200-mata, pērā i ngā mea whakakoi whakarewa, ngā rauemi uku karāhe, me ngā rauemi whatu haurua-ira. Ko te mahi tuatahi ko te huri. I tēnei wā, me whakamahi koe i tētahi mīhini huri korundum 200-mata te kaha. Ko Guilin Hongcheng tētahi umanga R&D me te hanga taputapu huri nui matatau ā-motu. Ko te mira pendulum raupapa HC i whakawhanakehia e ia he kōwhiringa pai mō tētahi mīhini huri korundum 200-mata te kaha.

He maha ngā momo tauira e wātea ana mō ngā mira hurihuri raupapa HC, me ngā putanga ia hāora mai i te 1 tana ki te 50 tana. He pumau te taputapu ina tīmatahia, he pai te hiri o te pūnaha pēhanga kino, he ma, he pai te taiao o te awheawhe, he watea te tiaki o ia rā, ā, he iti te utu whakahaere me te tiaki. He whānuitia te whakamahinga i roto i te umanga ātete ahi, ā, he nui te mahi.

Kei te piki haere te rongonui o te mīhini huri kōrundum Guilin Hongcheng 200 mesh hei taputapu nui i roto i te tukatuka kohuke me te whakarite rauemi nā te mea he tino whai hua, he penapena pūngao, he tiaki taiao hoki. Hei rauemi huri kounga teitei, kei te tipu haere tonu te hiahia o te mākete mō te kōrundum, ā, he whānui ngā tirohanga a te mākete. Nau mai ki te whakapā mai ki a mātou mō ngā utu hou.
