Kwimimandla yokuvelisa ephezulu efana nee-semiconductors kunye ne-precision optics, iziseko zokusila ze-granite ziye zaba zizinto ezibalulekileyo kwizixhobo eziphambili ngenxa yokuzinza kwazo okuhle kunye nokumelana nokuguguleka. Nangona kunjalo, imakethi izaliswe ziimveliso zomgunyathi nezimbi ezidlula imabula, ilitye lokwenziwa kunye nelitye elidayiweyo, elingakhokeleli nje kuphela ekunciphiseni ukuchaneka kwezixhobo, kodwa linokubangela ilahleko enkulu. Eli nqaku libonelela ngesikhokelo sokuchonga ngokwesayensi esivela kwiinkalo ezintathu: iipropati zezinto, iindlela zovavanyo, kunye neenkqubo zokuqinisekisa, ukukunceda uphephe imigibe yabathengi.
I. Iimpawu zezinto ezibonakalayo: Ulwazi oluSisiseko lokuchonga iFihla
1. Izalathisi eziqinileyo zoxinano kunye nobunzima
I-granite yokwenyani: Uxinano lwayo ludla ngokuba phakathi kwe-2600 kunye ne-3100kg/m³ (i-granite emnyama ekumgangatho ophezulu efana neemveliso ze-ZHHIMG® inokufikelela ngaphezulu kwe-3000kg/m³), kunye nobunzima be-Mohs obuyi-6 ukuya kwi-7. Xa ingqekembe ikrwelwa kumphezulu wayo, akukho mkhondo ushiyekileyo.
Imveliso yobuxoki: Ubunzima bemabula bumalunga ne-2500-2700kg/m³, kwaye ubunzima bayo bungama-3-5 kuphela. Ukukrwela kancinci kwingqekembe kushiya uphawu. Ubunzima belitye elenziweyo buyatshintshatshintsha kakhulu kwaye lenza isandi esingathandekiyo xa libethwa (ngelixa igranite yokwenyani isenza isandi esicacileyo).
2. Umahluko kwi-microscopic kwisakhiwo kunye noburhabaxa
I-granite yendalo: Yenziwe ngamasuntswana eeminerali afana ne-quartz kunye ne-feldspar adityaniswe ngokusondeleyo. Ubume bayo bunamabala okanye imivimbo engalinganiyo, kwaye icandelo layo elinqamlezileyo lirhabaxa kwaye linomnqondo ocacileyo we-granular.
Ilitye elidayiweyo: Ubume bomphezulu bubuthuntu. Bunokubuthuntu xa busulwa nge-alcohol, kwaye umbala wecandelo elinqamlezileyo wahluke kakhulu kowomphezulu. Ubume bemabula buyimigca eqhubekayo kwaye buqulathe iikristale zecalcium carbonate (eziya kubila xa i-hydrochloric acid inyibilikisiwe kuzo).
Ii. Uvavanyo lweSayensi: Ukutyhila Ubuxoki ngeDatha
1. Uvavanyo olusisiseko lokusebenza
2. Ukuchongwa kwezixhobo zobungcali
Ukufunyanwa kweziphene ze-ultrasonic: I-granite yokwenyani ayibonisi ziphene ezibonakalayo ngaphakathi, ngelixa izinto zobuxoki zinokuba neentanda okanye ukubonakaliswa okungenanto.
Uhlalutyo lwe-X-ray diffraction: Lunokuchonga ngokuchanekileyo ukwakheka kwezimbiwa (i-granite iqulethe i-quartz kunye ne-feldspar, ngelixa i-marble yenziwe nge-calcite).
Iii. Inkqubo yeSatifikethi: Isatifikethi esisemthethweni sokuthintela umngcipheko
Uluhlu lwamaxwebhu ekufuneka ahlolwe
Ubungqina bokulandeleka kwemithambo yentsimbi: Kwigranite yokwenyani, kufuneka kunikwe ulwazi oluthile malunga negori (njengeShandong Jinan Black, Indian Black).
Ingxelo yovavanyo lomntu wesithathu: Kubandakanya idatha ephambili efana noxinano, ubulukhuni, kunye ne-coefficient of thermal expansion (ekhutshwe yilabhoratri eqinisekisiweyo ye-CNAS okanye ye-ISO 17025);
Isiqinisekiso soMgangatho we-ISO: Abavelisi abaqhelekileyo kufuneka baphumelele isiqinisekiso senkqubo yolawulo lomgangatho we-ISO 9001, kwaye iimveliso eziphezulu kufuneka zihambisane nesiqinisekiso sokusingqongileyo se-ISO 14001.
2. Lumka kwimigibe yeentengiso zobuxoki
Iimveliso ezithi "ziilitye ezisetyenziswa kuyo yonke into" okanye "ubulukhuni obungaphaya kwendalo" uninzi lwazo zizinto ezisetyenziswayo.
Iziseko ezingenazo iiparameter ezithile zobugcisa (ezifana nokuthe tye kunye nokuthe tye) kufuneka zithengwe ngononophelo.
Iimveliso ezixabiso lazo liphantsi ngama-30% kunomndilili wemarike kusenokwenzeka ukuba zibe zezomgunyathi okanye ezingaphantsi komgangatho.
