Munyaya yemidziyo yekuyera nemazvo, kururama nekugadzikana kwemidziyo zvine chekuita zvakananga nekururama kwemhedzisiro yekuyera, uye sarudzo yezvinhu zvekutakura nekutsigira chishandiso chekuyera zvakakosha. Granite nemarble, sezvinhu zviviri zvematombo zvemhando yepamusoro, zvinowanzo fungidzirwa pakuvaka michina yekuyera nemazvo, asi ndeipi iri nani? Ngationgororei zvakadzama.
Kuenzanisa kugadzikana
Kugadzikana ndiyo nheyo yemichina yekuyera zvakarurama. Granite inoumbwa yakadzika mukati mepasi, mushure mekudziya kwakanyanya uye kumanikidzwa kwakanyanya kwenguva yakareba, chimiro chemukati chakasimba uye chakafanana. Mamiriyoni emakore ekukwegura kwechisikigo anoita kuti kushushikana kwayo kwemukati kubviswe zvizere, izvo zvinoita kuti granite igadzikane zvakanyanya. Kana zvinhu zvakaita sekupisa nehunyoro zvichichinja, granite inoshanduka zvishoma.
Kusiyana neizvi, marble, kunyange zvazvo ichiumbwawo mushure mekuita kwenguva refu kwe geology, asi chimiro chayo chekristaro chakakora, uye musanganiswa wacho une zvicherwa zvakawanda zvakaita secalcium carbonate. Hunhu uhwu hunoita kuti marble ikure kana kupwanyika zviri nyore kana tichitarisa shanduko dzezvakatipoteredza. Semuenzaniso, munzvimbo ine tembiricha yakakura, shanduko yehukuru hwemarble inogona kukanganisa kurongeka kwekuyera kwemidziyo yekuyera chaiyo, nepo granite ichigona kuchengetedza kugadzikana zviri nani uye kupa hwaro hwakavimbika hwemidziyo yekuyera.
Kuoma uye kuramba kupfeka
Midziyo yekuyera nemazvo painoshandiswa kwenguva refu, ichatambura nekukakavadzana kwakasiyana-siyana uye kugongana. Granite yakaoma muchimiro, uye kuomarara kwayo kweMohs kunowanzoita kunge 6-7, izvo zvinogona kudzivirira kupfeka kwekunze nekukwenywa. Mukuisa uye kufamba kwezvishandiso zvekuyera nemasampuli kakawanda, pamusoro pegranite hazviregi kusiya zviratidzo zvakajeka, kuitira kuti irambe yakati sandara uye yakarurama kwenguva yakareba.
Kuomarara kwematombo emarble kwakaderera, uye kuomarara kweMohs kunowanzova 3-5. Izvi zvinoreva kuti pasi pemamiriro akafanana ekushandiswa, pamusoro pematombo emarble panogona kukwenywa nekusakara, uye kana kutsvedzerera kwepasi kwakuvara, zvichakanganisa kururama kwemidziyo yekuyera nemazvo. Pamidziyo yekuyera inoda kushanda kwenguva refu uye nemazvo, kuomarara kwakanyanya uye kuramba kupfeka kwegranite pasina mubvunzo isarudzo yakanaka kwazvo.
Kuongorora kuramba ngura
Makemikoro akasiyana-siyana anogona kunge aripo munzvimbo yekuyera, akadai sekushanduka kweacid-base reagents, izvo zvinokonzeresa kuramba kwengura kwezvinhu zvemuchina. Granite inonyanya kuumbwa nequartz, feldspar nezvimwe zvicherwa, hunhu hwemakemikari hwakagadzikana, hune kuramba kwakanaka kweacid, kuramba alkali. Munzvimbo dzakaoma dzemakemikari, granite inogona kuchengetedza hunhu hwayo hwepanyama uye hwemakemikari kwenguva yakareba kuti ive nechokwadi chekuti michina yekuyera chaiyo inoshanda zvakanaka.
Nekuda kwekushanda kwemakemikari kwechikamu chayo chikuru checalcium carbonate, marble inowanzobatwa nemakemikari kana ikasangana nezvinhu zvine acidic, zvichikonzera ngura nekukuvadzwa pamusoro. Kuora uku hakuzongokanganisi chitarisiko chemarble chete, asiwo kuparadza kugadzikana kwayo, uye zvobva zvakanganisa kunyatsojeka kwemidziyo yekuyera chaiyo. Nokudaro, munzvimbo yekuyera uko kune njodzi yekuora kwemakemikari, kuramba ngura kwegranite kunoita kuti ive chinhu chakavimbika.
Kugadzikana kwakakwana, kuomarara uye kuramba kupfeka uye kuramba ngura nezvimwe zvinhu, granite muzviratidzo zvakasiyana-siyana zvakakosha yakaratidza zviri nani pane mashandiro emabhura. Kune michina yekuyera chaiyo inoda kunyatsorongeka uye kugadzikana, granite pasina mubvunzo isarudzo yakakodzera. Inogona kupa hwaro hwakasimba uye hwakavimbika hwezvishandiso zvekuyera, kuve nechokwadi chekururama uye kuvimbika kwemhedzisiro yekuyera, uye kubatsira kushanda kwekuyera kwakarurama mukutsvaga kwesainzi, kugadzirwa kwemaindasitiri nedzimwe nzvimbo kuti zviitwe zvakanaka.
