Ngomahluko phakathi kwemarble kunye negranite

Indlela yokwahlula imabula kwigranite kukubona ipateni yazo. Ipateni yeimabulaityebile, ipateni yomgca igudile, kwaye utshintsho lombala lutyebile.igraniteIipateni zinemibala ecacileyo, azinazo iipateni ezicacileyo, kwaye imibala ngokubanzi imhlophe kwaye ingwevu, kwaye iyafana.

IIgranite
I-granite yeyamatye anqabileyo, eyenziwa kukuqhuma kwe-magma engaphantsi komhlaba kunye nokuhlasela kwe-crystallization epholileyo kunye namatye e-metamorphic e-granite. Ngolwakhiwo lwekristale olubonakalayo kunye nobume bayo. Yenziwe yi-feldspar (ngesiqhelo i-potassium feldspar kunye ne-oligoclase) kunye ne-quartz, ixutywe nenani elincinci le-mica (i-mica emnyama okanye i-mica emhlophe) kunye neeminerali ezilandelelanayo, ezifana ne-zircon, i-apatite, i-magnetite, i-ilmenite, i-sphene njalo njalo. Icandelo eliphambili le-granite yi-silica, enomxholo wayo umalunga ne-65% - 85%. Iipropati zekhemikhali ze-granite zibuthathaka kwaye zine-asidi. Ngokwesiqhelo, i-granite imhlophe okanye ingwevu kancinci, kwaye ngenxa yeekristale ezimnyama, imbonakalo yayo inamachaphaza, kwaye ukongezwa kwe-potassium feldspar kuyenza ibe bomvu okanye ibe nenyama. I-granite eyenziwe yi-magmatic epholisa kancinci i-crystallization, ingcwatywe nzulu phantsi komhlaba, xa isantya sokupholisa sicotha ngokungaqhelekanga, iya kwenza ubume oburhabaxa be-granite, eyaziwa ngokuba yi-crystalline granite. I-granite kunye namanye amatye ekristale aseka ipleyiti yelizwekazi, ekwayeyona litye lixhaphakileyo elingena livezwa kumphezulu womhlaba.

Nangona igranite ithathwa njengezinto ezinyibilikayo okanye i-igneous rock magma, kodwa kukho ubungqina obuninzi obubonisa ukuba ukwakheka kwegranite ethile yimveliso yokuguqulwa kwendawo okanye ilitye langaphambili, ayisebenzi ngenkqubo yolwelo okanye yokunyibilika kwaye ihlengahlengise kwaye iphinde iphindwe. Ubunzima begranite buphakathi kwe-2.63 kunye ne-2.75, kwaye amandla ayo okucinezela yi-1,050 ~ 14,000 kg/sq cm (15,000 ~ 20,000 pounds nge-square intshi). Ngenxa yokuba igranite inamandla kunesanti, ilitye lekalika kunye nemarble, kunzima ukuyikhupha. Ngenxa yeemeko ezikhethekileyo kunye neempawu zesakhiwo esiqinileyo segranite, ineempawu ezilandelayo ezizodwa:
(1) inomgangatho olungileyo wokuhombisa, ingasebenza kwiindawo zikawonke-wonke nakwindawo yokuhombisa yangaphandle.
(2) ukusebenza kakuhle kokucubungula: ukusarha, ukusika, ukupolisha, ukubhola, ukukrola, njl. Ukuchaneka kwayo kokulungisa kungaba ngaphantsi kwe-0.5 mu m, kwaye ukukhanya kungaphezulu kwe-1600.
(3) ukumelana nokuguguleka kakuhle, ngokuphindwe ka-5-10 kunentsimbi ephosiweyo.
(4) i-thermal expansion coefficient incinci kwaye akulula ukuyiguqula. Ifana ne-indium steel, enobushushu obuncinci kakhulu.
(5) imodulus enkulu elastiki, ephezulu kunentsimbi ephosiweyo.
(6) iqinile, i-inner damping coefficient inkulu, iphindwe kalishumi elinesihlanu kunentsimbi. Ayinawo umbane, i-shock absorber.
(7) igranite iyaphuka kwaye ilahleka kancinci emva komonakalo, nto leyo engayichaphazeliyo indlela ethe tyaba ngayo yonke indawo.
(8) iipropati zeekhemikhali zegranite zizinzile kwaye azilula ukuzinyamezela, nto leyo enokumelana ne-asidi, i-alkali kunye nokugqwala kwegesi. Iipropati zayo zeekhemikhali zihambelana ngqo nomxholo we-silicon dioxide, kwaye ubomi bayo benkonzo bunokuba malunga neminyaka engama-200.
(9) igranite ine-magnetic field engaqhubiyo, engaqhubiyo kunye ne-stable field.

Ngokwesiqhelo, i-granite yahlulwe yangamacandelo amathathu ahlukeneyo:
Iigranite ezintle: ububanzi obuqhelekileyo bekristale yefeldspar yi-1/16 ukuya kwi-1/8 ye-intshi.
Igranite ephakathi: ububanzi obuqhelekileyo bekristale yefeldspar bumalunga ne-1/4 ye-intshi.
Iigranite ezirhabaxa: ububanzi obuqhelekileyo bekristale yefeldspar bumalunga ne-1/2 intshi kwaye ububanzi bukhulu, ezinye zide ziye kuthi ga kwiisentimitha ezimbalwa. Ubuninzi beegranite ezirhabaxa buphantsi kakhulu.
Kwiminyaka yakutshanje, i-granite ibandakanya i-83% yezinto zamatye ezisetyenziswa ekwakheni iisikhumbuzo kunye ne-17% yemabula.

Iimabula
I-marble yenziwe ngamatye e-metamorphic amatye e-sedimentary kunye namatye e-sedimentary, kwaye lilitye le-metamorphic elenziwe emva kokuphinda kusetyenziswe i-limestone, ngokuqhelekileyo kunye nokwakheka kweentsalela zezinto eziphilayo. Icandelo eliphambili yi-calcium carbonate, umxholo wayo umalunga ne-50-75%, eyi-alkaline encinci. Amanye ama-marble aqulethe isixa esithile se-silicon dioxide, amanye awanazo i-silica. Imigca yomphezulu ngokubanzi ayiqhelekanga kwaye inobunzima obuphantsi. Ukwakheka kwema-marble kuneempawu ezilandelayo:
(1) ipropati elungileyo yokuhombisa, imabula ayinayo imitha kwaye ikhanya kwaye inemibala, kwaye isetyenziswa kakhulu ekuhombiseni udonga nomgangatho ngaphakathi. Ukusebenza kakuhle koomatshini bokuchwetheza: ukusarha, ukusika, ukupolisha, ukubhola, ukukrola, njl.njl.
(2) imabula ineempawu ezilungileyo zokumelana nokuguguleka kwaye ayilungi lula, kwaye ubomi bayo benkonzo ngokubanzi bumalunga neminyaka engama-50-80.
(3) kushishino, imabula isetyenziswa kakhulu. Umzekelo: isetyenziselwa izinto zokwenza imveliso eluhlaza, i-cleaner agent, i-metallurgical solvent, njl.njl.
(4) imabula ineempawu ezifana nentsimi engaqhubiyo, engaqhubiyo kunye neyomeleleyo.

Ngokwembono yeshishini, onke amatye ekalika endalo nacwebezelayo abizwa ngokuba yimabula, njengoko kunjalo ngamanye amadolomite kunye namatye enyoka. Ekubeni ingeyiyo yonke imabula efanelekileyo kuzo zonke iziganeko zokwakha, imabula kufuneka yahlulwe ibe ziindidi ezine: A, B, C kunye no-D. Le ndlela yokuhlela isebenza ngokukodwa kwimabula ye-C kunye ne-D eqhotsiweyo, efuna unyango olukhethekileyo ngaphambi kokufakwa okanye ukufakwa.
