Pamberi pekugadzira nemazvo uye kutsvaga tsvakurudzo yesainzi, chikanganiso chega chega chinogona kuva "chipingamupinyi" chinodzivirira kubudirira. Semudziyo unokosha wekugadzirisa kufamba nemazvo, kushanda kwepuratifomu yekufamba inoyerera yemhepo inotenderera zvine chekuita nehunhu uye kubudirira kwemhedzisiro. Pakati pezvinhu zvakawanda zvinopesvedzera, hwaro hwegranite, hune hunhu hwayo husina muganho, hwave chinhu chikuru chekuona kuti puratifomu inoshanda zvakanaka.
Granite, mushure memamiriyoni emakore ekuchinja kwenzvimbo, chimiro chemukati chakasimba uye chakafanana, kunyanya nequartz, feldspar nezvimwe zvicherwa zvakabatana zvakanyanya. Chimiro ichi chakasiyana chakagadzirwa nenzira yechisikigo chinopa hwaro hwegranite hunhu hwakasiyana-siyana.
Yakasimba zvikuru, yakaparadzaniswa nekukanganiswa kwekunze
Kudedera munzvimbo yekunze imhandu yekururamisa kwepuratifomu yemhepo inoyerera nechisimba chakasimba. Kudedera kunokonzerwa nekushanda kwemichina mikuru nemidziyo pasi pefekitori uye traffic yakapoteredza kunogona kuendeswa kupuratifomu inofamba nepasi. Zvisinei, hwaro hwegranite hwakaita se "nhare inodzivirira kudengenyeka kwenyika" yakasimba. Maumbirwo aro akaomarara ekristaro anogona kudzivirira uye kuderedza kudedera, uye kuburikidza nemiedzo inoshanda, amplitude yekudedera inoendeswa kupuratifomu inogona kuderedzwa neinopfuura 80%. Muworkshop yekugadzira machipisi e semiconductor, maitiro ephotolithography anoda kurongeka kwenzvimbo kuti asvike padanho re nanometer, uye puratifomu yekufamba yemhepo inoyerera nechisimba chakasimba inotsigirwa negranite base inogona kuve nechokwadi chekuti michina yechip lithography inoshanda zvakanaka munzvimbo yakaoma yekudedera, kupedzisa kunyora kwepatani yedunhu nemazvo, uye kuvandudza zvikuru goho rekugadzira machipisi.
Kugadzikana kwakanaka kwekupisa, kusatya kuchinja kwekupisa
Kuchinja-chinja kwetembiricha kuchaita kuti zvinhu zvakawanda zviwedzere uye zviderere, izvo zvinokanganisa kururama kwemidziyo. Zvisinei, hwaro hwegranite hunoratidza kugadzikana kukuru kwekupisa, uye coefficient yayo yekuwedzera kwekupisa yakaderera zvikuru, kazhinji pa5-7 × 10⁻⁶/℃. Mumunda wezvenyeredzi, chikuva chekufamba kwemhepo inoyerera nemhepo chaiyo chinoshandiswa kugadzirisa malenzi makuru eteresikopu, nehwaro hwegranite, kunyangwe paine shanduko huru mukusiyana kwekupisa pakati pemasikati neusiku, chinogona kuve nechokwadi chekuti kururama kwenzvimbo yelenzi kunochengetwa padanho re sub-micron, zvichibatsira vaongorori venyeredzi kubata zvakajeka shanduko dzisinganyatsooneki dzemitumbi yekudenga iri kure uye kuongorora zvakavanzika zvemuchadenga wakadzika.
Kuomarara kwakanyanya uye kuramba kupfeka kuitira kuti ive nechokwadi chekushandiswa kwenguva refu
Mukufamba kwenguva refu kwepuratifomu inoyangarara yemhepo inomanikidza isina kusimba, kunyangwe paine rutsigiro rwemhepo inoyangarara pakati pepuratifomu nehwaro, kuchine mwero wakati wekukweshana. Kuomarara kwegranite kwakakwira, kuomarara kweMohs kunogona kusvika 6-7, nekusapfeka zvakanaka. Murabhoritari yesainzi yezvinhu, puratifomu inowanzoshandiswa yekufamba kwemhepo inomanikidza isina kusimba, hwaro hwayo hwegranite hunogona kudzivirira kurasikirwa kwekukweshana kwenguva refu, zvichienzaniswa nehwaro hwakajairika, hunogona kuwedzera kutenderera kwekuchengetedza kwepuratifomu neinopfuura 50%, kuderedza mari yekugadzirisa michina, uye kuona kuti basa rekutsvagisa kwesainzi rinoenderera mberi.
Kusarudzwa kwehwaro hwegranite kuti pave nepuratifomu yekufamba inoyerera yemhepo inomanikidza isina kusimba ndiyo nzira yekupedzisira yekuona kuti zvinhu zvinofamba zvakanaka, zvakagadzikana uye zvinogara kwenguva refu. Muminda yekugadzira semiconductor, kugadzira zvishandiso zve optical, aerospace, tsvakiridzo yesainzi uye kuyedza, izvo zvinoda kunyatsojeka, puratifomu yekufamba inoyerera yemhepo inomanikidza isina kusimba inotsigirwa nehwaro hwegranite iri kutamba basa guru risingatsiviwi, richikurudzira kukura kwemaindasitiri akasiyana-siyana kuti asvike pakunyatsojeka.
