I-Abrasives ihlala ibizwa ngokuba "ngamazinyo emizi-mveliso" kwicandelo lezemveliso. Ngokubhekisele kwityathanga lonke lezorhwebo, abrasive sisixhobo sokwenza imveliso, ukugaya, ukugaya nokucoca, phantse zonke iimveliso zemizi-mveliso. Ukongeza ekusetyenzisweni ngokubanzi koomatshini kunye namanye amashishini okucoca isinyithi, abrasive bayasetyenziswa ekuqhubekiseni ukutya okuziinkozo, kumzi mveliso wamaphepha kunye nasekwenzeni izinto ezingasetyenziswanga ezifana neceramics, iglasi, ilitye, ipulasitiki, irabha, iinkuni, njl njl. Isengqiqweni yokutsho ukuba usetyenziso olubanzi kunye nexabiso eliphakamileyo lemveliso yezixhobo ezikhulu kakhulu kufuneka laziwe. Ngapha koko, phantsi kwemvelaphi yokuba ifanitshala entsha, iimoto zemidlalo ezigqithileyo kunye neemveliso zobugqi ezibonakala zingumxholo ophambili wase China okwangoku, abrasives bayilibale kwaye bangaziwa.
Kutheni le nto kunjalo? Iingcali zatsho ukuba isizathu kukuba nangona i China ingumvelisi omkhulu we-Abrasives, ayisiyiyo imveliso eyomeleleyo kwaye inefuthe elincinci. Ngokwedatha, umjikelo wophuhliso ophakathi kwee abrasives ezintsha eTshayina ziinyanga ezili-18, kwaye umjikelo wobomi bemveliso yiminyaka eli-10 ukuya kweli-15. Kumazwe angaphandle, "ezintathu ezintathu" ziye zafunyanwa, oko kukuthi, ubomi beemveliso yiminyaka emithathu, umjikelo wokuveliswa kwemveliso uneenyanga ezintathu, kwaye umjikelo wokuyilwa kwemveliso uneeveki ezintathu. Abantu abanoluvo oluncinci bayazi ukuba kuphela xa izixhobo zokwenza izixhobo zivelisiwe zinokwenza ishishini lokuvelisa lenze inkqubela phambili kubuchwepheshe bemveliso. Ke ngoko, umgangatho wezinto ezisetyenziswayo, ukuveliswa kwesiphelo esiphakamileyo okanye hayi, ukuya kuthi ga kwinqanaba elithile, kuthintela ukuphuculwa komzi mveliso wonke wokuvelisa.
Izixhobo zokugaya kufuneka zikumgangatho ophezulu, ingabi lixabiso eliphantsi
kwimarike yangaphakathi, umgangatho ophantsi kunye nexabiso eliphantsi liyathandwa. Ukusukela oko kwenziwa uhlengahlengiso kunye nokuvula, nangona itekhnoloji yokuvelisa kunye nemigangatho yovavanyo ye-abrasives yenze inkqubela phambili enkulu, kusekho umsantsa omkhulu xa kuthelekiswa neemveliso zasemanzini zangaphandle. Kuyo yonke imakethi yekhaya, okokuqala, umxholo wethekhnoloji yemveliso uphantsi kwaye ixabiso elongeziweyo lincinci; Okwesibini, umgangatho wamashishini awunangqondo, amashishini amakhulu makhulu kodwa awomeleleyo, amashishini amancinci amancinci kodwa awakhethwanga. Kwaye iimveliso ezibekwe ngamashishini angaphandle e-China azilungelanga iimeko zokusebenza zase China, kwaye iimveliso ezifakwe zixabiso eliphantsi.
Ii-abrasives akufuneki ukuba zingaziwa kangako, iimveliso eziphezulu zokuphela ziyimfuno zophuhliso
Ukusukela kumbono woqoqosho, uphuhliso lwezixhobo ezinamandla kufuneka luphumelele kunye nokuchuma kwemizi mveliso. Kule minyaka idlulileyo, urhulumente usebenzise izicwangciso zophuhliso lwasentshona, ukunyuka kumbindi we-China ne-Haixi Zone yezoqoqosho, komeleza ukwakhiwa kwedolophu, kwaye kwakha inani elikhulu leeprojekthi eziphambili, ezinjengokudluliselwa kwerhasi ngasempuma, eNtshona ukuya eMpuma ukuhambisa umbane, uMazantsi ukuya kuMantla aManzi aMantla, uloliwe wethafa nomgaqo kaloliwe ohamba ngesantya esiphezulu. Ulwakhiwo olubanzi kangako luya kuthi ngokuqinisekileyo lukhokelele kuphuhliso lomzi mveliso. Kwangelo xesha, ishishini lokuvelisa elikhulayo lidale imfuno enkulu yezixhobo zemveliso, ngakumbi abrasives. Ngaphantsi kwesikhokelo salo mkhwa, iimveliso zokuphela eziphezulu ziya kuthatha indawo yeabrasives zemveli ezisezantsi kunye nexabiso eliphantsi.
