Munyika yematombo echisikigo, granite inomira sechiratidzo chekugara kwenguva refu uye kushandiswa kwakasiyana-siyana. Kubva pazvivakwa zvekare kusvika kune zvivako zvemazuva ano, dombo iri rine igneous rakaratidza kukosha kwaro mukushandiswa kwaro kwakawanda. Asi chii chinoita kuti granite ive yakakosha kudaro? Mhinduro yacho iri mukugadzirwa kwayo kwakasiyana kwemakemikari uye hunhu hwayo hunoshamisa hunoisiyanisa nemamwe matombo.
Makemikoro eGranite
Hunhu hweGranite hwakasiyana hunotangira padanho remamorekuru. Dombo iri rine matombo akakora rinonyanya kuumbwa nezvicherwa zvitatu: quartz, feldspar, uye mica. Quartz, ine 60-70% yemusanganiswa wegranite, ndiyo inoita kuti dombo iri rive rakaomarara uye rirambe richirwisa kukweshwa. Feldspar, inoumba 12-15% yemusanganiswa, inoshanda sechinobatanidza, ichibata dombo pamwe chete uye ichipa simba rayo rose. Mica, kunyangwe iripo muhuwandu hudiki, inowedzera chitarisiko chakasiyana chegranite nehunhu hwayo hwekuratidzira.
Makemikoro chaiwo egranite anosanganisira silicon dioxide (SiO₂) pa60-70%, aluminium oxide (Al₂O₃) pa12-15%, uye huwandu hushoma hwepotassium oxide (K₂O), sodium oxide (Na₂O), calcium oxide (CaO), iron oxide (Fe₂O₃), uye magnesium oxide (MgO). Musanganiswa uyu wezvicherwa nema oxide ndiwo unopa granite kugara kwayo kwenguva refu uye kuramba kutonhora.
Hunhu Hwemuviri Hunokosha
Kupfuura makemikari ayo, granite ine hunhu hunoshamisa hwemuviri hunoita kuti ive yakakodzera kushandiswa kwakasiyana-siyana. Nekuwanda kwe 2.6-2.7g/cm³, granite inorema uye yakasimba, inokwanisa kutsigira huremu hwakakura pasina kutsemuka kana kukanganisika. Mwero wayo wekunwa mvura uri pasi pe 0.5%, zvichiita kuti irambe yakasimba pakukuvadzwa nehunyoro uye kusvibiswa nemavara kana yakavharwa zvakanaka.
Chimwe chezvinhu zvinonyanya kuzivikanwa zvegranite kuoma kwayo, kazhinji kuri pakati pe6-7 paMohs scale. Izvi zvinoiisa pasi pedhaimani, corundum, uye topaz, zvichiita kuti isanyanya kukwenywa kana kusakara. Kuoma uku kwakanyanya kwakabatana zvakananga nehuwandu hwayo hwe quartz, iyo inoitawo basa rakakosha mukuona mashandiro edombo mumaindasitiri.
Kukanganiswa kweQuartz muKushanda zvakanaka kweKukuya
Munzvimbo dzemaindasitiri, huwandu hwegranite mu quartz hune simba rakananga pakushanda zvakanaka kwekugadzira. Zvidzidzo zvakaratidza kuti pakuwedzera kwega kwega kwe10% kwehuwandu hwe quartz, pane kuwedzera kwe8.5% kwehuwandu hwekubvisa zvinhu panguva yekushanda kwekukuya. Hukama uhwu hwakakosha zvikuru mukugadzirwa kwezvikamu nematurusi akanyatsogadzirwa uko granite inoshandiswa sechinhu chepakutanga.
Kuwanda kwe quartz hakungobatsiri chete pakukuya zvakanaka asiwo kunobatsira kuti dombo rigare rakagadzikana. Izvi zvinoita kuti granite ive sarudzo yakanaka yezvishandiso zvekuyera zvakarurama, zvakaita semapuratifomu epamusoro nemabhenji ekuona, uko kuchengetedza saizi chaiyo kwakakosha.
Zvinodiwa zveNordic zveHigh-Feldspar Granite
Kuchamhembe kweEurope, kunyanya munyika dzakadai seNorway neSweden, kune mhando dzakasiyana dzegranite dzine feldspar yakawanda. Muenzaniso unoshamisa iLundhs Blue granite, ine feldspar inosvika 35-40%. Kuwanda kwefeldspar uku kunoita kuti dombo iri rive nechitarisiko chebhuruu-grey chakasiyana icho chave chichidiwa zvikuru mumabasa ekuvaka nekugadzira.
Kudiwa kwegranite ine feldspar yakakura muNordic hakungobvi pakunaka kwayo chete asiwo kubva pakubatsira kwayo. Feldspar inobatsira kuti dombo rishande zvakanaka, zvichiita kuti rive nyore kucheka nekugadzira uku richichengetedza chimiro charo. Kuenzana uku kwerunako uye mashandiro aro kwakaita kuti Lundhs Blue nemagranite akafanana ave sarudzo dzakakurumbira kune zvese kubva kumacountertops kusvika pakufukidza mumapurojekiti ekuvaka epamusoro-soro.
ASTM C615 Standards: Kuve nechokwadi chehunhu uye kuenderana
Kuti ive nechokwadi chekuti granite inoshandiswa mukuvaka nemaindasitiri ine mhando uye kuenderana, sangano reAmerican Society for Testing and Materials (ASTM) rakaisa mwero weASTM C615. Mwero uyu unotsanangura zvinodiwa pamatombo egranite, kusanganisira huwandu hushoma hweSiO₂ hwe65%, izvo zvakakosha pakuona kuti dombo racho rakasimba uye rinoita basa zvakanaka.
ASTM C615 inosanganisira zvinhu zvakasiyana-siyana zvegranite, kusanganisira hunhu hwezvinhu, kutora sampuro, kuyedzwa, uye chitupa. Nekutevedzera mitemo iyi, vagadziri nevatengesi vanogona kuvimbisa kuti zvigadzirwa zvavo zvegranite zvinosangana nezvinodiwa zvepamusoro-soro zvekusimba, kugara kwenguva refu, uye kugadzikana kwehukuru. Kunze kweKuvakwa: Granite muTekinoroji Yemazuva Ano
Kunyange zvazvo granite ichizivikanwa zvikuru nekushandiswa kwayo mukuvaka nekuvaka, mashandisirwo ayo anopfuura kushandiswa kwetsika uku. Munyika yetekinoroji yemazuva ano, granite inoita basa rakakosha mukugadzira zvinhu nemazvo.
Imwe nzira isingatarisirwi yekushandisa iri mukugadzira mashandisirwo emushandisi, uko zvikamu zveAEM Granite UI zvave zviyero zveindasitiri. Zvikamu izvi, zvakatumidzwa zita rekuti zvine simba uye zvakavimbika, zvinoshandiswa mukugadzira masisitimu ekutarisira zvemukati uye ruzivo rwedhijitari. Kufananidza negranite kunoratidza kugadzikana uye kugara kwenguva refu kunotsvagwa nevagadziri muhurongwa uhu hweUI.
Kukanganiswa Kwekucherwa Nekugadzirwa kweGranite Kwakatipoteredza
Sezvineiwo nechero chiwanikwa chechisikigo, kucherwa nekugadzirisa granite kune zvakunokanganisa nharaunda zviri kuramba zvichigadziriswa neindasitiri. Nzira dzemazuva ano dzekuchera matombo dzine chinangwa chekuderedza kukanganiswa kwezvakatipoteredza, nemakambani ari kuita zvirongwa zvekudzoreredza nzvimbo dzakacherwa kuti dzive dzadzo dzechisikigo mushure mekunge mabasa amira.
Panyaya yekuchengetedza nguva, kugara kwenguva refu kwegranite ibhenefiti huru. Zvivakwa zvakavakwa negranite zvinogona kugara kwemazana emakore, zvichideredza kudiwa kwekutsiviwa kakawanda uye mari inoshandiswa pakuchengetedza nharaunda. Uyezve, kuramba kupisa kwegranite kunoita kuti ive sarudzo isingadyi simba zvakanyanya pakuvaka madziro emadziro, zvichibatsira kudzora tembiricha yemukati uye kuderedza mitengo yekupisa nekutonhodza.
Remangwana reGranite Munyika Iri Kuchinja
Sezvatinotarisira ramangwana, granite inoramba ichichinja zvinoenderana nezvinodiwa nevanhu. Kuvandudzwa kwemaitiro ekugadzirisa kuri kuita kuti granite ive nekushanda kwakasiyana-siyana kupfuura kare, zvichibvumira kucheka kwakatetepa uye magadzirirwo akaomarara. Izvi hazvingowedzere kunaka kwayo chete asiwo zvinoderedza mari yekushandisa zvinhu uye yekufambisa.
Munyaya yekuvaka zvinogara kwenguva refu, granite iri kuramba ichizivikanwa nekuda kwekubatsira kwayo zvakatipoteredza. Kuumbwa kwayo kwechisikigo kunoita kuti ive chinhu chekuvaka chisina chepfu, chisina mwaranzi, uye hunhu hwayo hwekupisa hunobatsira mukuchengetedza simba muzvivakwa. Sezvo indasitiri yekuvaka iri kufambira mberi kune tsika dzinogara kwenguva refu, basa regranite rinogona kukura zvakanyanya.
Mhedziso: Kukwezva Kusingaperi kweGranite
Kubva pakuumbwa kwayo kwemakemikoro akaomarara kusvika pakushandiswa kwayo kwakasiyana-siyana mumaindasitiri emazuva ano, granite inoramba iri chinhu chinosarudzwa kune avo vanotsvaga kugara kwenguva refu, runako, uye mashandiro. Musanganiswa wayo wakasiyana wehunhu hwayo, pamwe chete nekusiyana-siyana kwerunako rwayo, zvinoita kuti granite irambe iri chinhu chikuru mukuvaka, dhizaini, uye tekinoroji kwemakore anotevera.
Sezvataongorora mativi akasiyana-siyana egranite, kubva pakuumbwa kwayo kwezvicherwa kusvika pakukwanisa kwayo kukuya zvakanaka, zviri pachena kuti dombo iri rechisikigo harisi kungori chinhu chekuvaka chete. Ihwo humbowo hwemaitiro epasi uye chiyeuchidzo chekuti zviwanikwa zvechisikigo zvinogona kushandiswa sei kusangana nezvinodiwa nevanhu nenzira dzinogara kwenguva refu uye itsva.
Ungave uchiyemura chiyeuchidzo chekare, kushanda nematurusi akanyatsogadzirwa, kana kushandisa masisitimu eUI epamusoro-soro, simba regranite riripo kwese kwese. Kuyevedza kwayo kusingaperi uye hunhu hwayo hunogara kwenguva refu zvinovimbisa kuti granite icharamba iri musimboti wekubudirira kwevanhu kwezvizvarwa zvinotevera.
