Kusiyana pakati pa nsanja yolondola ya granite ndi nsanja yolondola ya marble?

1. Kusiyana kwa zinthu zakuthupi
Granite: Granite ndi mwala wa igneous, womwe umapangidwa makamaka ndi mchere monga quartz, feldspar ndi mica, wokhala ndi kuuma kwambiri komanso kuchulukana kwambiri. Kuuma kwake kwa Mohs nthawi zambiri kumakhala pakati pa 6-7, zomwe zimapangitsa kuti nsanja ya granite ikhale yabwino kwambiri pankhani yolimbana ndi kuwonongeka komanso kukana dzimbiri. Nthawi yomweyo, kapangidwe ka granite ndi kofanana komanso kolimba, ndipo imatha kupirira kupsinjika kwakukulu ndi katundu, zomwe ndizoyenera kwambiri poyesa molondola komanso kukonza zinthu.
Marble: Mosiyana ndi zimenezi, marble ndi mwala wosinthika, womwe umapangidwa makamaka ndi calcite, dolomite ndi mchere wina. Ngakhale marble ilinso ndi zinthu zabwino kwambiri, monga kuuma kwambiri, kukhazikika kwambiri, ndi zina zotero, kuuma kwake kwa Mohs nthawi zambiri kumakhala pakati pa 3-5, komwe kumakhala kocheperako pang'ono kuposa granite. Kuphatikiza apo, mtundu ndi kapangidwe ka marble ndi kolemera komanso kosiyanasiyana, ndipo nthawi zambiri amagwiritsidwa ntchito pazochitika zokongoletsera. Komabe, pankhani yoyezera molondola ndi makina, kuuma kwake kochepa komanso kapangidwe kake kovuta kungakhale ndi zotsatirapo pa kulondola.
Chachiwiri, kusiyana pakati pa zochitika zogwiritsira ntchito
Pulatifomu yolondola ya granite: Chifukwa cha mawonekedwe ake abwino komanso kukhazikika kwake, nsanja yolondola ya granite imagwiritsidwa ntchito kwambiri pazochitika zolondola kwambiri, monga kukonza makina molondola, kuyesa zida zamagetsi, kuyendetsa ndege ndi zina. M'madera awa, cholakwika chilichonse chaching'ono chingayambitse zotsatirapo zoyipa, kotero ndikofunikira kwambiri kusankha nsanja ya granite yokhala ndi kukhazikika kwakukulu komanso kukana kuwonongeka.
Nsanja yolondola ya marble: Nsanja ya marble ilinso ndi kulondola kwakukulu komanso kukhazikika, koma kuchuluka kwa momwe imagwiritsidwira ntchito ndi kwakukulu. Kuphatikiza pa kuyeza ndi kukonza molondola, nsanja za marble nthawi zambiri zimagwiritsidwa ntchito m'ma laboratories, mabungwe ofufuza zasayansi ndi zochitika zina zomwe zimafuna kuyesa ndi kuyesa kolondola kwambiri. Kuphatikiza apo, kukongola ndi kukongoletsa kwa nsanja ya marble kumapangitsanso kuti ikhale malo m'magawo ena apamwamba kwambiri okongoletsera.
3. Kuyerekeza magwiridwe antchito
Ponena za magwiridwe antchito, nsanja yolondola ya granite ndi nsanja yolondola ya marble zili ndi ubwino wawo. Mapulatifomu a granite amadziwika ndi kuuma kwawo kwakukulu, kukana kuwonongeka kwambiri komanso kukhazikika kwakukulu, zomwe zimatha kusunga kulondola komanso kukhazikika kwa nthawi yayitali m'malo ovuta ogwirira ntchito. Nsanja ya marble imakondedwa ndi ogwiritsa ntchito chifukwa cha mtundu wake wolemera komanso kapangidwe kake, magwiridwe antchito abwino komanso mtengo wake wocheperako. Komabe, pakafunika kulondola kwambiri, nsanja za granite nthawi zambiri zimapereka zotsatira zoyezera zokhazikika komanso zodalirika.
Chidule cha IV.
Mwachidule, pali kusiyana kwakukulu pakati pa nsanja yolondola ya granite ndi nsanja yolondola ya marble pazikhalidwe za zinthu, zochitika zogwiritsira ntchito ndi magwiridwe antchito. Wogwiritsa ntchito ayenera kuganizira mozama malinga ndi zosowa zenizeni komanso malo ogwiritsira ntchito posankha. Pazochitika zomwe zimafuna kulondola kwambiri komanso kukhazikika, nsanja za granite mosakayikira ndiye chisankho chabwino; Pazochitika zina zomwe zili ndi zofunikira zina pakukongoletsa ndi kukongoletsa, nsanja za marble zingakhale zoyenera kwambiri.
