Chikuva chegranite chikuva chakagadzirwa negiraniti. Yakagadzirwa kubva padombo regneous, granite ibwe rakaoma, rekristaro. Pakutanga inoumbwa nefeldspar, quartz, uye granite, inopindirana neine imwe kana kupfuura maminerari matema, ose akarongwa muyunifomu pateni.
Granite inonyanya kuumbwa nequartz, feldspar, uye mica. Feldspar inoverengera 40% -60%, uye quartz ye20% -40%. Ruvara rwayo rwunoenderana nemhando uye huwandu hwezvikamu izvi. Granite idombo rakanyatsojeka. Yepamusoro-soro granite ine zviyo zvakanaka uye zvakafanana, chimiro chakakora, quartz yakakwira, uye inopenya feldspar sheen.
Granite ine yakakwira silica yemukati, ichiita dombo rine acidic. Mamwe magranite ane tyisidziro yezvikamu zveradioactive element, saka aya marudzi egranite anofanirwa kudziviswa kushandiswa kwemukati. Granite ine dense chimiro, yakaoma kugadzirwa, uye inoshingirira kune acids, alkalis, uye mamiriro ekunze, zvichiita kuti ive yakakodzera kushandiswa kwenguva refu kunze. Granite ine zvinotevera maitiro:
1. Granite ine dense structure, high compressive simba, kunyura kwemvura yakaderera, kuoma kwepamusoro pepamusoro, kugadzikana kwakanaka kwemakemikari, uye kusimba kwakasimba, asi kushomeka kwemoto.
2. Granite ine granular structure ine yakanaka, yepakati, kana coarse tsanga, kana porphyritic chimiro. Mbeu dzayo dzakafanana uye dzakanaka, dzine mapeji maduku (porosity inowanzova 0.3% kusvika 0.7%), kunyura kwemvura yakaderera (kazhinji 0.15% kusvika 0.46%), uye kupikisa kwakanaka kwechando.
. Simba rayo rekushanduka-shanduka rinowanzova pakati pe10 ne30 MPa.
Chechina, granite ine goho repamusoro, inogoneka kune akasiyana siyana ekugadzirisa, uye ine yakanakisa slab splicing zvivakwa. Uyezve, granite haisi nyore kunyura, zvichiita kuti ive yakakodzera kune zvekunze zvekushongedza.
Kuchengeta chikuva chemarble (marble slab) kunoda kutarisisa kushivirira uye kuchengetedza zvinodiwa zveiyo marble papuratifomu, pamwe nekuona kana nzvimbo yebasa ine makomba. Kana nzvimbo yemarble iine makomba madiki pamusoro payo, inofanira kudzorerwa kufekitari kuti igadziriswe. Kana iyo chaiyo yakangochinja, kugadzirisa kunofanira kuitwa panzvimbo yekushandiswa. Mushure menguva refu, kushandiswa nguva dzose, chikuva chemarble chichaita Kana iyo marble platform yakanyanyisa, kukanganisa kwechokwadi kuchawedzera zvishoma nezvishoma, zvichiita kuti zvive zvisina kururama. Muchiitiko ichi, zvinoda kugadziriswa.
Matanho ekugadzirisa emapuratifomu emarble:
1. Tarisa kurongeka kwepuratifomu yemarble uye uone kukanganisa kwazvino.
2. Gaya-kuya chikuva chemarble uchishandisa mabrasives uye maturusi ekukuya kuti uwane kuenzana kunodiwa.
3. Yechipiri semi-fine kugaya kwepuratifomu yemarble mushure mekukuya kwakakasharara ndeyekubvisa makwara akadzika uye kuwana nhanho inodiwa.
4. Geya nzvimbo yekushanda yepuratifomu yemarble kuti uwane iyo inodiwa chaiyo.
5. Edzai kurongeka kwepuratifomu yemarble mushure mekupenya, uye zvakare mushure menguva yakati.
