Zvinhu zviri pasi pegranite zvinokanganisa sei kugadzikana kwayo kwenguva refu uye kuchengetedza kururama kwayo?

Rudzi uye mhando yezvinhu zvegranite zvinoshandiswa sehwaro hwemuchina wekuyera we coordinate (CMM) zvakakosha kuti igare yakasimba uye yakarurama kwenguva refu. Granite isarudzo yezvinhu zvinofarirwa nevanhu nekuda kwehunhu hwayo hwakanaka hwakadai sekugadzikana kwakanyanya, kuwedzera kupisa kushoma, uye kuramba kupfeka nekuora. Muchinyorwa chino, tichaongorora kuti mhando dzakasiyana dzezvinhu zvegranite dzinogona sei kukanganisa kugadzikana uye kururama kweCMM.

Chekutanga, zvakakosha kunzwisisa kuti hazvisi zvese zvinhu zvegranite zvakafanana. Granite inogona kusiyana zvichienderana nehunhu hwayo hwepanyama uye hwemakemikari zvichienderana nenzvimbo yainobva, mhando, uye maitiro ekugadzira. Hunhu hwezvinhu zvegranite zvinoshandiswa huchasarudza kugadzikana uye kururama kweCMM, izvo zvakakosha pakugadzira nekugadzira nemazvo.

Chimwe chinhu chakakosha chekufunga nezvacho ihuwandu hwe quartz mu granite. Quartz imineral inokonzeresa kuomarara uye kugara kwenguva refu kwegranite. Granite yemhando yepamusoro inofanira kunge iine huwandu hwe quartz hunosvika 20% kuti ive nechokwadi chekuti chinhu chacho chakasimba uye chinogona kutsungirira huremu nekudengenyeka kweCMM. Quartz inopawo kugadzikana kwehukuru, izvo zvinodiwa pakuyera nemazvo.

Chimwe chinhu chekufunga nezvacho inyaya yekuti granite ine maburi mangani. Granite ine maburi inogona kunwisa hunyoro nemakemikoro, izvo zvinogona kukonzera ngura nekukanganisika kwehwaro. Granite yemhando yepamusoro inofanira kunge isina maburi mangani, zvichiita kuti isapindike mumvura nemakemikoro. Izvi zvinovandudza zvakanyanya kugadzikana uye kururama kweCMM nekufamba kwenguva.

Kupedzwa kwechigadziko chegranite kwakakoshawo. Chikamu cheCMM chinofanira kunge chakagadzirwa zvakanaka kuti chipe kugadzikana kwakanaka uye kururama kwemuchina. Kana chigadzirwa chisina kunaka, chinogona kunge chine maburi, mavanga, nezvimwe zvikanganiso pamusoro zvinogona kukanganisa kugadzikana kweCMM.

Mukupedzisa, mhando yezvinhu zvegranite zvinoshandiswa muCMM zvine basa guru mukugadzikana kwayo kwenguva refu uye kuchengetedza kururama. Granite yepamusoro ine quartz yakakodzera, porosity shoma, uye kupenya kwepamusoro-soro kuchapa kugadzikana kwakanakisa uye kururama kwekushandisa pakuyera. Kusarudza mutengesi ane mukurumbira anoshandisa granite yepamusoro kugadzira michina yavo yekuyera kuchaita kuti CMM igare kwenguva refu uye kuyerwa kwakarurama nguva dzose.
