Ngaba iQonga lam leGranite liya kuphuka? Ukuqina, ukuBumba, kunye neeNgcebiso zokuGcinwa kweNgcali

I-Igneous Core yokuChaneka kweShishini

Xa utyalo-mali kwi-platform ye-granite echanekileyo ye-ZHHIMG® okanye icandelo, umbuzo wendalo uvela: ingaba ihlala njani? Impendulo emfutshane yile: yomelele ngokumangalisayo. Igranite lilitye elitshisayo, elakhiwe phantsi kobushushu obukhulu kunye noxinzelelo olunzulu emhlabeni. Le mvelaphi inika imfezeko yolwakhiwo engahambelani nezixhobo ezininzi ezenziweyo.

Igranite yimatrix eqinileyo, eyikristale equlunqwe ikakhulu yiquartz, feldspar, kunye ne mica. Kwizicelo zethu zokusebenza eziphezulu, sibeka phambili i-granite ngeenkozo ezintle, ezifanayo kunye ne-compact, isakhiwo esixineneyo. Olu qulunqo luguqulela ngokuthe ngqo kwinto eyomeleleyo, ezinzileyo, kunye ne-inert yekhemikhali.

Ukuqonda izinto eziluncedo zeGranite ezingaqhawukiyo

Ngelixa kungekho nto "engenakophuka" ngokwenene, iimpawu zendalo zegranite ekumgangatho ophezulu ziyenza ixhathise kakhulu kuxinzelelo lwemeko yokuvelisa efunekayo:

• Ukuqina okuKhethekileyo kunye namandla: I-Granite ibeka phezulu kwisikali sobulukhuni be-Mohs (malunga ne-6) kwaye iqhayisa amandla acinezelayo aphezulu, ehlala idlula i-300 MPa kwiindidi ze-fine-grained ezisetyenziswa yi-ZHHIMG®. Oku kuthetha ukuba ixhathisa kakhulu ekungeneni nasekukrwelweni ngexesha lokusetyenziswa kwesiqhelo.
• Ixinene kwaye Ayinamanzi: Igranite yethu echanekileyo ibonakalisa isakhiwo esishinyeneyo esine-porosity ephantsi kakhulu (ngokuqhelekileyo ingaphantsi kwe-0.7%) kunye nokufunxa okuncinci kwamanzi (ngaphantsi kwe-0.5%). Olu xinaniso lubalulekile kuzinzo lwekhemikhali kunye nokuqina, okwenza ukuba luxhathise kakhulu kwiiasidi kunye nealkali-inzuzo ebalulekileyo kwiintsimbi.
• IMfezeko yoLwakhiwo: I-Granite iyaziwa ngezinga eliphezulu lesivuno kunye nokukwazi ukuba ii-slabs zayo zihlanganiswe ngokulula ngelixa zigcina ingqibelelo yesakhiwo. Kwiziseko zobunzima beZHHIMG®, amandla ayo aphezulu e-flexural (ngokuqhelekileyo i-10-30 MPa) iqinisekisa ukuzinza naphantsi kwemithwalo enzima kakhulu.

Ngaba ingaqhawuka? Phantsi kweemeko zokusebenza eziqhelekileyo, akukho. Iqonga legraniti lenziwe ukuba likwazi ukumelana noxinzelelo olukhulu. Nangona kunjalo, njengayo nayiphi na imathiriyeli yekristale, inokukrolwa okanye iqhekeke ukuba iphantsi kwempembelelo ebukhali, egxininisiweyo, okanye ukuba iwisiwe ukusuka kumphakamo. Yingakho ukuphatha ngokucophelela ngexesha lofakelo luhlala luyimfuneko.

ULondolozo lweNgcali: Ukukhusela ukuchaneka kweNanometer

Ngokungafaniyo nentsimbi etyhidiweyo, i-granite ayigqwali okanye igxume, yenza ukugcinwa kube lula kakhulu. Nangona kunjalo, ukugcina umgangatho we-nanometer ukuchaneka kwe-ZHHIMG® ukuhambisa, ukuqinisekiswa kwexesha kunye nenkonzo kubalulekile. Injongo kukulungisa ukuchaneka okuncinci okubangelwa kukuguga okukhulayo, hayi ukusilela kwezinto.

Nantsi indlela yokusebenza yobuchwephesha yokuqinisekisa ubomi obude kunye nokuchaneka kweqonga lakho legranite:

1. Uvavanyo oluchanekileyo: Inkqubo ihlala iqala ngokutshekisha ngokuchanekileyo ukuchaneka kwangoku kweqonga kusetyenziswa izixhobo eziqinisekisiweyo ze-metrology, ezifana ne-laser interferometers. Eli nyathelo limisela uluhlu lwempazamo kwaye lichaza umda ochanekileyo wokugcinwa okufunekayo.
2. UVavanyo loMphezulu: Umphezulu wokusebenza ujongwa ngokubonakalayo nangoomatshini ukuba kukho nakuphi na ukunxitywa okubalulekileyo okanye imingxuma. Ukuba ukunyamezela ngokuchanekileyo kuye kwasuka nje-isiphumo esiqhelekileyo sokusetyenziswa kwexesha elide-iqonga lingumviwa oyintloko wokulungiswa kwendawo kunye nokulungiswa kwakhona.
3. Ukubuyisela Ukubuyisela (Ukuba Kuyimfuneko): Ukuba ukulungiswa kuyafuneka, umphezulu ulungiswa ngononophelo. Le yinkqubo enamanqanaba amaninzi:
   • Ukusila ngokurhabaxa: Ukugaya kwasekuqaleni, ngokuqhelekileyo kusetyenziswa i-abrasives, ukufezekisa imfuno ephambili ye-flatness kumanqanaba amanqanaba, ukususa imikrwelo enzulu kunye nokunxiba.
   • Semi-Fine Grinding: Inqanaba lenguquko lokususa amanqaku ashiywe kukusila ngokurhabaxa kunye nokusondeza iqonga kufutshane nengcaciso yalo yokugqibela yokucaba.
4. Ukugqityezelwa kokuGqibela ukuChaneka: Inqanaba lokugqibela libandakanya ukugqithwa okukhethekileyo komphezulu wokusebenza ukufezekisa ukunyamezela okungqongqo okufunekayo. Apha kulapho ubuchwephesha bamagcisa ethu obuchule bungena ngokwenene, bubuyisela ukuchaneka koqobo okuchaziweyo.
5. Ukuqinisekiswa kwe-Post-Lapping: Ukulandela inkqubo yokugqiba, ukuchaneka kweqonga kuqinisekiswa ngokukhawuleza. Okubaluleke kakhulu, sincoma ukulandelwa kokulandelela ngokuchanekileyo emva kwexesha lokuzinzisa ukuqinisekisa ukuba iqonga lizinze ngokugqibeleleyo kwindawo yalo, liqinisekisa ukuthembeka kwalo okuqhubekayo.

Ngokuqonda ukomelela, isayensi yendalo emva kwe-ZHHIMG® granite kunye nokubambelela kwezi protokoli zogcino zobungcali, uyaqinisekisa ukuba iqonga lakho elibalulekileyo lihlala lingumgangatho othembekileyo wereferensi kangangamashumi eminyaka.
