Izidingo Zobuchwepheshe Zezingxenye Zemishini Zemabula Negranite

Izingxenye zemishini zemabula negranite zisetshenziswa kabanzi emishinini yokunemba, imishini yokulinganisa, kanye namapulatifomu ezimboni ngenxa yokuqina kwazo okuhle kakhulu, ubulukhuni obuphezulu, kanye nokumelana nokuguguleka. Ukuqinisekisa ukunemba nokuqina, izidingo zobuchwepheshe eziqinile kumele zilandelwe ngesikhathi senqubo yokuklama nokukhiqiza.

Imininingwane Yobuchwepheshe Ebalulekile

1. Umklamo Wokuphatha
   Kuzingxenye zemabula zeBanga 000 kanye neBanga 00, kunconywa ukuthi kungabikho ziphatho zokuphakamisa ezifakwayo ukuze kulondolozwe ubuqotho besakhiwo kanye nokunemba.

2. Ukulungiswa Kwezindawo Ezingasebenzi
   Ama-dents amancane noma amakhona aqhephukile ezindaweni ezingasebenzi angalungiswa, uma nje amandla esakhiwo engathinteki.

3. Izidingo Zezinto Ezibalulekile
   Izingxenye kufanele zikhiqizwe kusetshenziswa izinto ezicolekile nezinobukhulu obuphezulu njenge-gabbro, i-diabase, noma imabula. Izimo zobuchwepheshe zifaka:

   • Okuqukethwe kwe-biotite kungaphansi kuka-5%

   • Imodulus enwebekayo engaphezu kuka-0.6 × 10⁻⁴ kg/cm²

   • Izinga lokumuncwa kwamanzi lingaphansi kuka-0.25%

   • Ubulukhuni bomphezulu osebenzayo ngaphezu kwama-70 HS

4. Ubulukhuni Bomphezulu

   • Ubulukhuni bomphezulu osebenzayo (Ra): 0.32–0.63 μm

   • Ubulukhuni bomphezulu oseceleni: ≤10 μm

5. Ukubekezelela Ubungako Bokusebenza Okubanzi
   Ukunemba kokuthamba kumele kuhambisane namanani okubekezelelana achazwe ezindinganisweni zobuchwepheshe ezihambisanayo (bheka Ithebula 1).

6. Ukuthamba Kwezindawo Eziseceleni

   • Ukubekezelelana kokusicaba phakathi kwezindawo eziseceleni nezindawo zokusebenza, kanye naphakathi kwezindawo eziseceleni ezimbili eziseduze, kufanele kuhambisane neBanga 12 le-GB/T1184.

7. Ukuqinisekiswa Kokuthamba
   Uma ukuthamba kuhlolwa kusetshenziswa izindlela ezivundlile noma zegridi, inani lokuguquguquka kwendiza yezinga lomoya kumele lihlangabezane nokubekezelelana okucacisiwe.

8. Ukusebenza Kokuthwala Imithwalo

   • Indawo ephakathi nendawo ethwala umthwalo, umthamo womthwalo olinganisiwe, kanye nokuphambuka okuvunyelwe kumele kuhlangabezane nezidingo ezichazwe kuThebula 3.

9. Amaphutha Okungaphezulu
   Indawo yokusebenza kumele ingabi namaphutha amakhulu athinta ukubukeka noma ukusebenza, njengemigodi yesihlabathi, ama-air pores, imifantu, izinto ezifakiwe, imigodi yokushwabana, imihuzuko, ama-dente, noma amamaki okugqwala.

10. Izimbobo Nemigoqo Enemicu
    Kwezingxenye zemabula noma zegranite zebanga 0 kanye nebanga 1, imigodi noma izikhala ezifakwe izintambo zingaklanywa phezu kwendawo, kodwa indawo yazo akufanele ibe phezulu kunobuso bokusebenza.

Isiphetho

Izingxenye zemishini zemabula negranite ezinembayo kakhulu kumele zilandele izindinganiso zobuchwepheshe eziqinile ukuqinisekisa ukunemba kokulinganisa, amandla okuthwala umthwalo, kanye nokuzinza kwesikhathi eside. Ngokukhetha izinto zekhwalithi ephezulu, ukulawula ikhwalithi yobuso, kanye nokususa amaphutha, abakhiqizi bangaletha izingxenye ezinokwethenjelwa ezihlangabezana nezidingo eziqinile zezimboni zemishini yokunemba yomhlaba wonke kanye nokuhlolwa.
