Kusukela ezikhathini zasendulo abantu wasebenzisa limestone for ukwakhiwa. Ngaphezu kwalokho, lena idwala sedimentary is sihluke kakhulu umsungulo egwadle namanye amatshe. Izingcezu lime amatshe wenza kusuka okuqinile impahla yemvelo, okuyinto bahlanganisa ikakhulu i-calcium carbonate (calcite).
ulwazi olujwayelekile mayelana zokwakha
Lime limbiwa cishe yonke indawo eRussia emaphakathi, ngoba kahle esakazwa, kulula ukucubungula futhi has chemical kakhulu futhi izakhiwo ngokomzimba. Yingakho-ke isetshenziswa kabanzi ngakho ekwakhiweni, ngemuva isihlabathi futhi amatshe izinto kuphela. Lime imfucumfucu kungaba ezihlukile. umbala kwakho kuncike ezihlukahlukene inclusions futhi akhiphe amanyela. Ngokuvamile, le nto has a olumhlophe, onsundu ngokuphaphathekile noma abe mpunga. Kwezinye izifunda ibizwa ngokuthi dolomite imfucumfucu. Its kwabantu ngobuningi kuyinto 2.2-2.7. Lime amatshe is etholwe ukuthena amaminerali yemvelo. Kamuva, yazenzela ukwelashwa okukhethekile zamakhemikhali. Phakathi kwezinye izinhlobo amatshe eshibhe.
Lime imfucumfucu: ukusetshenziswa emnothweni kazwelonke
Njengoba le nto uyidwala engazinzile, umkhiqizo wokugcina etholwe therefrom Ubuye amandla aphansi. Isikhathi esining impela limestone amatshe asetshenziswa imisebenzi komgwaqo. Akufanele sibakhohlwe ukuthi kuyinto kahle kulula esilufifi, okuyinto iyehlisa ukuphila inkonzo egandayiwe. Yingakho bangakwazi kuphela ufafaze umgwaqo nge umthwalo kancane traffic.
Muva nje, le nto isakhiwo ngokwethukela kusetshenziswa kakhulu ukwenziwa amabhlogo ezihlukahlukene imikhiqizo ukhonkolo kanye ukhonkolo. Ngokuvamile isetshenziselwa engadini. Ngenxa limestone imfucumfucu has a ongaphakeme emisebeni yangemuva, abantu abaningi bakhetha ukuhlanganisa ngayo ezinye izinhlobo zamatshe ochotshoziwe ukhonkolo. Le nhlanganisela izinto uphelele ubuciko namagceke driveways. Ethandwa kakhulu it has abanikazi iziza ezincane. Ngenxa impahla yayo mechanical eziphansi, kungaba kakhulu ukunciphisa izindleko kokuphothula umsebenzi.
Lokhu amatshe ingasetshenziswa yokukhiqiza isakhiwo lime, soda, calcium Carbide, umquba, fluxes ekukhiqizeni steel. Isetshenziselwa njengoba yamathebhu e Izingxube ehlukahlukene kwezohwebo izimboni ukuphrinta kanye namabhodlela. Kulo ukukhiqiza ecucuza ukwenziwa Portland usimende.
Izindleko zokwakha
Izinga le yokwakha normalizes GOST. Nechobozekile limestone amafraktjhini 40h70 uphawu 400 kuyinto ruble 401. / T. Uma sikhuluma 20x40 okunye, izindleko zawo - ruble 436 / t. futhi 5x20 -. ruble 531 / t (kufaka ne-VAT). Iningi izinkampani ezikhiqiza ngeziningi zezinto zokwakha, ekhiqizwa limestone imfucumfucu brand 600. intengo zihlukaniswe zibe izingxenyana ezincane ezahlukene kuyehluka kancane kuphela. Ngakho, e Moscow (eMoscow) imfucumfucu 40h70, 20x40 elibiza 850 ruble / imitha cubic, kanti elincane 5x20 - .. 870 ruble / imitha cubic .. (Nge-VAT). Ikhwalithi ngeziningi zezinto zokwakha kumele kuhambisane nezidingo GOST8267-93.
