Musiyano uripo pakati pemabhuru negranite
Nzira yekusiyanisa marble negranite ndeyekuona mapatani avo. Patani yemabhurayakapfuma, mutsetse wacho wakatsetseka, uye kuchinja kwemavara kwakapfuma.girenayitimapatani acho ane mavara matema, asina mapatani akajeka, uye mavara acho anowanzova machena negrey, uye akafanana.
IyoGranite
Granite ndeyedombo reigneous, iyo inoumbwa nekuputika kwe magma yepasi pevhu uye kupinda kwe crystallization inotonhorera uye metamorphic matombo e granite. Ine chimiro chekristaro chinoonekwa uye magadzirirwo. Inoumbwa ne feldspar (kazhinji potassium feldspar ne oligoclase) ne quartz, yakasanganiswa nehuwandu hushoma hwe mica (black mica kana white mica) uye trace minerals, dzakadai se: zircon, apatite, magnetite, ilmenite, sphene nezvimwewo. Chikamu chikuru chegranite isilica, ine huwandu hunosvika 65% - 85%. Hunhu hwemakemikari egranite hauna simba uye acidic. Kazhinji, granite inenge chena kana grey, uye nekuda kwemakristaro akasviba, chitarisiko chacho chine makwapa, uye kuwedzerwa kwe potassium feldspar kunoita kuti ive tsvuku kana nyama. Granite inoumbwa ne magmatic inotonhodza crystallization zvishoma nezvishoma, yakavigwa pasi pevhu, kana ikanonoka kutonhora, inoumba texture yakaoma kwazvo yegranite, inozivikanwa se crystalline granite. Matombo egranite nemamwe matombo ekristaro ndiwo anoumba hwaro hweplate yekondinendi, inovawo dombo rinonyanya kupindira rinoonekwa pamusoro penyika.
Kunyangwe granite ichionekwa sechinhu chakanyunguduka kana kuti igneous rock magma, asi kune humbowo hwakawanda hunoratidza kuti kuumbwa kwegranite kunokonzerwa nekushanduka kwenzvimbo kana dombo rekare, hazviiti kuburikidza nekuita kwemvura kana kunyunguduka uye kurongazve uye kudzokororwa. Huremu hwegranite huri pakati pe2.63 ne2.75, uye simba rayo rekumanikidza i1,050 ~ 14,000 kg/sq cm (15,000 ~ 20,000 pounds pa square inch). Nekuti granite yakasimba kupfuura sandstone, limestone nemarble, zvinonetsa kuibvisa. Nekuda kwemamiriro ezvinhu akakosha uye hunhu hwakasimba hwegranite, ine hunhu hunotevera hwakasiyana:
(1) ine zvishongo zvakanaka, inogona kushandiswa munzvimbo dzeveruzhinji nedzekunze.
(2) mashandiro akanaka ekugadzirisa: kucheka, kucheka, kupolisha, kuboora, kuveza, nezvimwewo. Kurongeka kwayo pakugadzira kunogona kunge kuri pasi pe 0.5 mu m, uye kupenya kwayo kunodarika 1600.
(3) inodzivirira kupfekwa zvakanaka, yakapetwa ka5-10 kupfuura simbi yakakandwa.
(4) chiyero chekuwedzera kwekupisa chidiki uye hachina kuoma kuchinjika. Chakafanana nesimbi ye indium, iyo ine tembiricha diki kwazvo.
(5) modulus hombe inonamira, yakakwirira kupfuura simbi yakaumbwa.
(6) yakasimba, chiyero chekunyorovesa chemukati chakakura, chakakura zvakapetwa ka15 kupfuura simbi. Haipindi shock, inonyungudutsa shock.
(7) granite inopwanyika uye inongorasika zvishoma mushure mekukuvadzwa, izvo zvisingakanganisi kutsveyama kwese.
(8) hunhu hwemakemikari egranite hwakagadzikana uye hahuna kuoma kuhugadzirisa, izvo zvinogona kuramba acid, alkali uye ngura yegesi. Hunhu hwayo hwemakemikari hwakaenzana zvakananga nehuwandu hwesilicon dioxide, uye hupenyu hwayo hwekushanda hunogona kusvika makore mazana maviri.
(9) granite ine simba remagineti risingafambise simbi, risingafambise simbi uye ine simba rakagadzikana.
Kazhinji, granite yakakamurwa kuita zvikamu zvitatu zvakasiyana:
Magranite akanaka: avhareji yedhayamita yekristaro yefeldspar i1/16 kusvika 1/8 ye inchi.
Granite ine girasi repakati nepakati: avhareji yedhayamita yekristaro yefeldspar inenge 1/4 ye inchi.
Magranite akakora: avhareji yedhayamita yekristaro yefeldspar inenge 1/2 inch uye dhayamita yakakura, mamwe akatosvika masendimita mashoma. Kuwanda kwemagranite akakora kwakaderera.
Mumakore achangopfuura, granite inoumba 83 muzana yezvinhu zvematombo zvinoshandiswa pakuvaka zviyeuchidzo uye 17 muzana yemabhura.
Iyomabhura
Marble inoumbwa kubva pamatombo ematombo e sedimentary nematombo e sedimentary, uye idombo re metamorphic rinoumbwa mushure mekudzokororwa kwe limestone, kazhinji ine magadzirirwo ezvasara zvehupenyu. Chinhu chikuru i calcium carbonate, iyo iri mukati mayo inenge 50-75%, iyo ine alkaline shoma. Mamwe marble ane huwandu hwakati hwe silicon dioxide, mamwe haana silica. Mitsetse yepamusoro inowanzo kuve isina kurongeka uye ine kuoma kwakaderera. Kuumbwa kwemarble kune zvinotevera:
(1) hunhu hwakanaka hwekushongedza, marble haina mwaranzi uye inopenya uye ine mavara, uye inoshandiswa zvakanyanya mukushongedza madziro nepasi mukati. Kushanda zvakanaka kwazvo mukugadzira: kucheka, kucheka, kupolisha, kuboora, kuveza, nezvimwewo.
(2) marumaru ane hunhu hwakanaka hunodzivirira kupera uye haakurumidzi kuchembera, uye hupenyu hwawo hwebasa hunowanzoita makore angangoita 50-80.
(3) mumaindasitiri, marumaru anoshandiswa zvakanyanya. Semuenzaniso: anoshandiswa pakugadzira zvinhu zvisina kugadzirwa, chekuchenesa, simbi inonyungudutsa, nezvimwewo.
(4) mabhura ane hunhu hwakadai semunda usingafambise mvura, usingafambise mvura uye wakagadzikana.
Kubva pamaonero ebhizinesi, matombo ese echisikigo uye akakweshwa edombo remarara anonzi marble, sezvakaita mamwe madolomite nematombo enyoka. Sezvo asiri ese marble akakodzera zviitiko zvese zvekuvaka, marble inofanira kukamurwa kuita zvikamu zvina: A, B, C naD. Nzira iyi yekupatsanura inonyanya kushanda kune marumaru eC neD akapfava, ayo anoda kurapwa kwakakosha asati aiswa kana kuiswa.
Kunamira kwedombo remarble kunotsigira kusimbisa nekudzivirira
Kupatsanura kwakananga ndekwekuti:
Kirasi A: marumaru emhando yepamusoro ane mhando imwecheteyo, yepamusoro-soro yekugadzirisa, asina tsvina uye stomata.
Kirasi B: chimiro chacho chiri pedyo nerudzi rwekare rwemarble, asi kunaka kwekugadzirisa kwacho kwakaderera zvishoma pane kwekutanga; Vane zvikanganiso zvechisikigo; Kupatsanurwa kudiki, kunamirwa uye kuzadza zvinodiwa.
C: pane musiyano mumhando yekugadzirisa; Zvikanganiso, stomata uye kuputsika kwemagadzirirwo azvo zvakajairika. Dambudziko rekugadzirisa misiyano iyi rinogona kuwanikwa nekuparadzanisa, kunama, kuzadza, kana kusimbisa imwe kana kupfuura yenzira idzi.
Kirasi D: hunhu hwayo hwakafanana nehwemhando C marble, asi ine zvikanganiso zvechisikigo, uye musiyano wemhando yekugadzirisa ndiwo mukuru, uye nzira imwechete inofanirwa kugadziriswa kakawanda. Rudzi urwu rwemarble rune matombo akawanda ane mavara, ane kukosha kwakanaka kwekushongedza.
Kusiyana kwekushandiswa kwegranite yemarble
Musiyano uri pachena pakati pegranite nemarble ndewekuti imwe inonyanya kugadzirwa panze uye imwe inonyanya kugadzirwa mukati. Zvizhinji zvezvinhu zvematombo echisikigo zvinoonekwa mukati mazvo ndezvemarble, nepo dombo rechisikigo rine makwapa riri pamugwagwa wekunze riri granite.
Sei paine nzvimbo yakajeka yekusiyanisa?
Chikonzero ndechekuti granite haiparari uye haiparari ngura, mhepo nezuva zvinogonawo kushandisa nguva refu. Pamusoro pezvo, zvichienderana negranite ine radioactive level, kune mhando nhatu dzeABC: zvigadzirwa zvekirasi A zvinogona kushandiswa chero mumamiriro ezvinhu, kusanganisira zvivako zvemahofisi nemakamuri emhuri. Zvigadzirwa zvekirasi B zvine radioactive kupfuura kirasi A, hazvishandiswe mukati meimba yekurara, asi zvinogona kushandiswa mukati nekunze kwezvimwe zvivako zvese. Zvigadzirwa zveC zvine radioactive kupfuura A neB, izvo zvinogona kushandiswa chete pakupedzisa kwekunze kwezvivakwa; kukosha kwekutonga kwematombo echisikigo kunopfuura C, kunogona kushandiswa chete pamadziro egungwa, mapiers nematombo edombo.
Mataira matema egranite emapurisa pasi pekirabhur
Mataira eGranite epasi rekunze
Matombo akanaka uye akakodzera kushongedza mukati. Nyika yematombo inoyevedza, yakajeka uye yakachena segirazi, ine zvishongo zvakasimba, saka inoshandiswa zvakanyanya mumunda weunyanzvi, muhoro huru yevanhu mune sikirini yematombo yakakura uye yakanaka kwazvo. Mwaranzi yematombo hainyanyi kukosha, uye kupararira kwematombo paInternet iguhu.
Musiyano wemutengo wegranite yemabhuru
Marabhu yeArabescato yekugezera
Kunyangwe granite nemarble zviri zvigadzirwa zvematombo zvemhando yepamusoro, musiyano wemutengo wakakura zvikuru.
Mapatani egranite ndeega, ruvara haruna kuchinja, ganda rekushongedza harina kusimba. Chakanakira ndechekuti rakasimba uye rinogara kwenguva refu, harisi nyore kukuvara, harina kudhayiwa, rinoshandiswa zvakanyanya kunze. Magranite anotangira pamadhora makumi kusvika kumazana emadhora, nepo mvere dzakachipa uye chiedza chinodhura.
Magadzirirwo emarble akapfava uye akapfava, kuchinja kwemavara kwakapfuma, mhando yakanaka ine pendi yenzvimbo, mapatani akanaka, marble idombo rehunyanzvi. Mutengo wemarble unosiyana kubva pamazana kusvika kuzviuru zveyuan, zvichienderana nekwakabva, mutengo wemhando dzakasiyana wakakura zvikuru.
Palissandro machena machena ekushongedza madziro
Kubva pahunhu, basa uye musiyano wemutengo, tinogona kuona kuti musiyano uripo pakati pezviviri izvi uri pachena. Ndinovimba kuti zviri pamusoro apa zvichakubatsira kusiyanisa marble negranite.
