Pa kusiyana kwa marble ndi granite

Njira yosiyanitsira marble kuchokera ku granite ndikuwona mawonekedwe awo. Chitsanzo chansangalabwindi wolemera, mzere wa mzere ndi wosalala, ndipo kusintha kwa mtundu kumakhala kolemera. Themwalamitundu yake ndi ya mathothomathotho, yopanda mawonekedwe, ndipo mitundu yake nthawi zambiri imakhala yoyera ndi imvi, ndipo imakhala yofanana.

TheGranite
Granite ndi ya mwala woyaka moto, yomwe imapangidwa ndi kuphulika kwa magma pansi pa nthaka ndi kuwukira kwa kuzizira kwa crystallization ndi miyala ya metamorphic ya granite. Ndi mawonekedwe a kristalo ndi mawonekedwe ake. Amapangidwa ndi feldspar (kawirikawiri potassium feldspar ndi oligoclase) ndi quartz, osakanikirana ndi mica yaing'ono (mica wakuda kapena mica woyera) ndi kufufuza mchere, monga: zircon, apatite, magnetite, ilmenite, sphene ndi zina zotero. Chigawo chachikulu cha granite ndi silika, zomwe zili pafupifupi 65% - 85%. Mankhwala a granite ndi ofooka komanso acidic. Kawirikawiri, granite ndi yoyera pang'ono kapena imvi, ndipo chifukwa cha makristasi amdima, mawonekedwe ake ndi amadontho, ndipo kuwonjezera kwa potassium feldspar kumapangitsa kukhala kofiira kapena minofu. Granite wopangidwa ndi magmatic pang'onopang'ono kuzirala crystallization, kukwiriridwa pansi pa dziko lapansi, pamene kuzizira kwapang'onopang'ono modabwitsa, kumapanga mawonekedwe ovuta kwambiri a granite, omwe amadziwika kuti crystalline granite. Granite ndi miyala ina ya crystalline imapanga maziko a continental plate, yomwenso ndi mwala wodziwika kwambiri wolowera padziko lapansi.

Ngakhale granite amaganiziridwa ndi zinthu zosungunula kapena igneous rock magma, koma pali umboni wochuluka umasonyeza kuti mapangidwe granite ena ndi mankhwala a deformation m'deralo kapena thanthwe yapita, iwo osati kudzera madzi kapena kusungunula ndondomeko ndi kukonzanso ndi recrystallization. Kulemera kwa granite kuli pakati pa 2.63 ndi 2.75, ndipo mphamvu yake yopondereza ndi 1,050 ~ 14,000 kg / sq cm (15,000 ~ 20, 000 mapaundi pa inchi imodzi). Chifukwa granite ndi yamphamvu kuposa mchenga, miyala yamchere ndi marble, ndizovuta kutulutsa. Chifukwa cha mawonekedwe apadera komanso mawonekedwe olimba a granite, ili ndi zotsatirazi:
(1) ili ndi ntchito yabwino yodzikongoletsa, imatha kugwiritsidwa ntchito kumalo a anthu komanso kukongoletsa kwakunja.
(2) kwambiri processing ntchito: sawing, kudula, kupukuta, kubowola, chosema, etc. Machining ake olondola akhoza kukhala pansi 0.5 mu m, ndi kuwala ndi pa 1600.
(3) kukana bwino kuvala, nthawi 5-10 kuposa chitsulo choponyedwa.
(4) choyezera chowonjezera chamafuta ndi chaching'ono komanso chosavuta kupunduka. Ndizofanana ndi zitsulo za indium, zomwe zimakhala zochepa kwambiri kutentha.
(5) zazikulu zotanuka modulus, apamwamba kuposa chitsulo chitsulo.
(6) olimba, mkati damping coefficient ndi lalikulu, 15 nthawi zazikulu kuposa chitsulo. Shockproof, shock absorber.
(7) granite ndi brittle ndipo amangotayika pang'ono pambuyo pa kuwonongeka, zomwe sizimakhudza flatness yonse.
(8) mankhwala a granite ndi okhazikika komanso osavuta kupirira, omwe amatha kukana asidi, alkali ndi dzimbiri la gasi. Mankhwala ake amafanana ndi zomwe zili mu silicon dioxide, ndipo moyo wake wautumiki ukhoza kukhala zaka 200.
(9) granite ili ndi mphamvu ya maginito yopanda conductive, yopanda maginito komanso malo okhazikika.

Nthawi zambiri, granite imagawidwa m'magulu atatu:
Ma granite abwino: pafupifupi awiri a feldspar crystal ndi 1/16 mpaka 1/8 ya inchi.
Granite wapakatikati: pafupifupi awiri a feldspar crystal ndi pafupifupi 1/4 inchi.
Ma granite okwera: pafupifupi mainchesi a feldspar crystal ndi pafupifupi 1/2 inchi ndi mainchesi okulirapo, ena mpaka ma centimita angapo. Kachulukidwe wa ma granite olimba ndi otsika.
M'zaka zaposachedwa, miyala ya granite imapanga 83 peresenti ya miyala ya miyala yomwe imagwiritsidwa ntchito pomanga zipilala ndi 17 peresenti ya marble.

Thensangalabwi
Marble amapangidwa kuchokera ku miyala ya metamorphic ya sedimentary rocks ndi sedimentary rocks, ndipo ndi thanthwe la metamorphic lomwe limapangidwa pambuyo pa kupangidwanso kwa miyala yamchere, nthawi zambiri ndi mawonekedwe a zotsalira zamoyo. Chigawo chachikulu ndi calcium carbonate, zomwe zili pafupifupi 50-75%, zomwe zimakhala zofooka zamchere. Mwala wina uli ndi silicon dioxide, ena alibe silika. Mizere ya pamwamba nthawi zambiri imakhala yosakhazikika komanso imakhala yolimba kwambiri. Mapangidwe a marble ali ndi zotsatirazi:
(1) malo abwino okongoletsera, marble alibe ma radiation ndipo ndi owala komanso okongola, ndipo amagwiritsidwa ntchito kwambiri m'kati mwa khoma ndi kukongoletsa pansi. Kuchita bwino kwa machining: kucheka, kudula, kupukuta, kubowola, kujambula, etc.
(2) miyala ya nsangalabwi ili ndi katundu wabwino wokana kuvala ndipo ndiyosavuta kukalamba, ndipo moyo wake wautumiki nthawi zambiri umakhala zaka 50-80.
(3) m'makampani, marble amagwiritsidwa ntchito kwambiri. Mwachitsanzo: ntchito zopangira, kuyeretsa wothandizila, metallurgical zosungunulira, etc.
(4) nsangalabwi ali ndi makhalidwe monga non-conductive, non-conductive ndi khola munda.

Kuchokera ku bizinesi, miyala yonse yachilengedwe ndi yopukutidwa ya miyala yamwala imatchedwa marble, monganso miyala ya dolomite ndi serpentine. Popeza si miyala yonse ya nsangalabwi yomwe ili yoyenera pamisonkhano yonse yomanga, nsangalabwi iyenera kugawidwa m’magulu anayi: A, B, C ndi D. Njira yogaŵirayi imagwira ntchito makamaka pamwala wonyezimira wa C ndi D, womwe umafunika chisamaliro chapadera asanayambe kuyika kapena kuyika. .

Gulu lachindunji lili motere:
Kalasi A: mwala wapamwamba kwambiri wokhala ndi zofanana, zabwino kwambiri zopangira, zopanda zinyalala ndi stomata.
Kalasi B: mawonekedwewo ali pafupi ndi mtundu wakale wa nsangalabwi, koma mawonekedwe ake ndi oyipa pang'ono kuposa woyamba; Kukhala ndi zolakwika zachilengedwe; Kupatukana kwakung'ono, gluing ndi kudzaza kumafunika.
C: pali zosiyana pakukonza khalidwe; Zowonongeka, stomata ndi fractures ndizofala kwambiri. Kuvuta kwa kukonza kusiyana kumeneku kungapezeke mwa kudzipatula, kumata, kudzaza, kapena kulimbikitsa njira imodzi kapena zingapo.
Kalasi D: Makhalidwewa ndi ofanana ndi mtundu wa C marble, koma uli ndi zolakwika zambiri zachilengedwe, ndipo kusiyana kwa khalidwe la processing ndilo lalikulu kwambiri, ndipo njira yomweyo imayenera kukonzedwa kangapo. Mtundu woterewu wa nsangalabwi ndi miyala yamtengo wapatali yamitundu yambiri, imakhala ndi zokongoletsera zabwino kwambiri.

Mitundu yosiyanasiyana ya miyala ya marble imagwiritsidwa ntchito
Kusiyana koonekeratu pakati pa granite ndi nsangalabwi ndikuti wina ali panja ndipo wina ali m'nyumba. Zambiri mwa miyala yachilengedwe yomwe imawonekera mkati ndi miyala ya marble, pomwe mwala wachilengedwe wamawanga wapanja ndi granite.

N’chifukwa chiyani pali malo oonekeratu oti tisiyanitse?
Chifukwa ndi granite kuvala zosagwira ndi kugonjetsedwa ndi dzimbiri, mphepo ndi dzuwa angagwiritsenso ntchito yaitali. Kuphatikiza apo, malinga ndi granite ya radioactive level, pali mitundu itatu ya ABC: zinthu zamagulu A zitha kugwiritsidwa ntchito munthawi iliyonse, kuphatikiza nyumba zamaofesi ndi zipinda zabanja. Zogulitsa zamtundu wa B zimakhala ndi radioactive kuposa kalasi A, zomwe sizimagwiritsidwa ntchito mkati mwa chipinda chogona, koma zimatha kugwiritsidwa ntchito mkati ndi kunja kwa nyumba zina zonse. C zopangira ma radio radioactive kuposa A ndi B, zomwe zingagwiritsidwe ntchito pomaliza kunja kwa nyumba; Kuposa mtengo wamtengo wapatali wa C wamtengo wapatali wa miyala yachilengedwe, ukhoza kugwiritsidwa ntchito ngati ma seawall, piers ndi miyala.
