Quicklime. Quicklime mtanda yomanga. ntchito

Mpaka nthawi imeneyo, mpweya laimu yomanga anali kugwiritsidwa ntchito mu mawonekedwe a slaked. I. Smirnov mu mmasate mungathe kugwiritsa ntchito zinthu zosiyanasiyana. Iye, ndipo kenako Osip BV anasonyeza kuti akamaziwononga, hydration oipa zakuthupi angayambe. Zimenezi ndi zofanana ndi kuwuma kwa Portland simenti kapena gypsum.

zambiri

Laimu - ndi paliponse mfundo dziko, kaphatikizidwe salembedwa kuwombera mankhwala (processing ndipo kenako) choko, miyala ndi miyala ina carbonate. Gulu ikuchitika malinga mipweya. Childs, mawu akuti "laimu" amatanthauza slaked laimu ndipo anachita mankhwala ake ndi madzi. zinthu izi zikhoza kukhala ufa, nthaka mtundu kapena mayeso. Chilinganizo yopsereza laimu - CaO. pawiri Izi ndi calcination mankhwala a macheka, imene kashiamu okusayidi amachita ngati zofunika chigawo chimodzi mankhwala. Iye amagwira amachitira ndi madzi. Chifukwa cha hydration a slaked laimu anapanga - Ca (o) _2.

Gawo

Malinga ndi mipweya ya osakaniza anali olekanitsidwa mpweya (makamaka ongokhala oxides ya magnesium ndi calcium) ndi hydrate (munali yambiri oxides chitsulo, zotayidwa, ndi pakachitsulo). Mu mafakitale ntchito mtanda laimu ndi quicklime yomanga ufa. Yotsirizira amadziwikanso ogaŵikana mitundu iwiri. Choyamba - laimu pansi quicklime. Mtundu wachiwiri amapangidwa ndi kugwiritsa ntchito luso lapadera. Kuzimitsira njira magnesia, calcium laimu ndi dolomitic ntchito zochepa madzi analandira slaked laimu (hydrated laimu). Pali mitundu ina. Zikuphatikizapo, makamaka monga perchloric, ndipo koloko-laimu.

kupanga

Chopangidwa laimu kwa kumanga ntchito zachilengedwe kashiamu ndi magnesium mitundu. Iwo makamaka zikuphatikizapo carbonate kashiamu ndi magnesium. Mu zikuchokera amakhala clays ndi admixtures mchenga. Pa matenthedwe processing (by Kutentha) mu ng'anjo ndi kutentha kwa 800 kwa 1200 madigiri kashiamu-mankhwala enaake a miyala kuyamba kuwola ndinso. Chifukwa cha ndondomeko iyi inatulutsa mankhwala enaake a okusayidi (MgO) na calcium (CaO) ndi mpweya.

Kagwiridwe yopangira zabwino akupera osakaniza

Laimu pansi quicklime akamagwira akupera kusakaniza mu ochiritsira mphero mpira. ntchito zawo ikuchitika mkombero chatsekedwa ndi kusiyanitsa linalake tinthu kukula olekanitsa. Nthawi zina, unit aikidwa mu separators ziwiri zotsatira. Izi kwambiri kumawonjezera zokolola. Pakali pano, mafunso pulverized laimu insufficiently otukuka. Kusankha ndondomeko kusinja mphero ndi madera zofunika kuganizira makamaka mlingo wa Kukuwotcha zakuthupi (kwambiri, sing'anga kapena mankhwala myagkoobozhzhenny). Onetsetsani kuganizira pamaso pa amatopa, unburned mpweya, pamaso pa zolimba. Mwamphamvu ndi sredneobozhzhennuyu laimu bwino pogaya, kumvera tinthu kumva kuwawa ake ndiponso kukwaniritsa. Izi ndi zomwe zimachitika mphero mpira. Tikumbukenso kuti mtima wa particles champhamvu loitanirana amafuna mphero lalifupi ndi kuwonongedwa mofulumira kwa kulemera okwana chisakanizo cha akuigwiritsa tuzigawo twa chabwino, komanso kugwiritsa ntchito njira kuti kuchepetsa loitanirana.

Ntchito quicklime ndi zopangidwa

Nkhanizi chimagwiritsidwa ntchito muzochitika zosiyana za ntchito anthu. Makasitomala yaikulu monga: akakhala zitsulo, ulimi, shuga, mankhwala, zamkati ndi makampani pepala. CaO ndi ntchito zomangamanga. Chofunika kwambiri ndi pawiri mu chilengedwe. Laimu ntchito kuchotsa sulfure okusayidi flue mpweya. Pawiri komweko akhoza pansi madzi ndi precipitate pano m'menemo zinthu organic ndi mankhwala. Komanso, ntchito ya laimu mwamsanga amapereka zachilengedwe neutralizing acidic ndi madzi ogwiritsidwa ntchito. Mu ulimi, pamene anakumana ndi dothi pawiri acidity kumatha zovulaza zomera mbewu. Quicklime kumalimbitsa nthaka ndi calcium. Izi kumawonjezera workability a dziko lapansi, Iyamba oipa a humus. Pa nthawi yomweyo ndi kuchepetsa kufunika asafe feteleza ntchito pa mlingo waukulu. The osakaniza hydrated ntchito nkhuku ndi ziweto kudyetsa. Kuthetsa kupanda kashiamu mu chakudya. Komanso, pawiri ntchito kuwongolera zinthu ambiri thanzi pamene kusunga ndi kuswana ziweto. Makampani mankhwala a hydrated laimu ndi adsorbents ntchito yokonza fluoride ndi hydrochloride calcium. Mu petrochemical makampani pawiri neutralizes ndi sludge asidi komanso amachita ngati reagent makamaka zochita kupanga ndi organic kaphatikizidwe. Laimu chimagwiritsidwa ntchito yomanga. Ichi ndi chifukwa zinthu mkulu zachilengedwe. The osakaniza ntchito yokonza binders, concretes ndi mortars, kwa kupanga mankhwala nyumbayi.

Quicklime micronized. ubwino

Quicklime, monga tanenera kale pamwambapa, ntchito kupanga concretes ndi mortars. pawiri Izi angapo ubwino. Makamaka, poyerekeza ndi hydrated laimu mu mawonekedwe a mtanda kapena ufa chisakanizo cha masamba finely anagawa palibe zinyalala. Ndi zigawo zake zonse pa oipa ntchito bwino kwambiri. Laimu pansi quicklime ndi zochepa kufunika madzi. Komanso padziko dera yake yeniyeni ndi kwambiri zochepa. Pa nkhani imeneyi, "workability" kapena konkire zochokera CaO njira zopezera pa maola buku la madzi. Kuchepetsa chofunika madzi konkire ndi mortars bwino bata awo pa kuumitsa. Pa hydration mu zosakaniza kale kukonzekera ya laimu chimamanga madzi (pa kusintha kuti hydrate - 32%). Izi zimathandiza kupeza mankhwala a concretes ndi mortars wa kachulukidwe mkulu ndi mphamvu. Mu ndondomeko ya kuumitsa kwa hydrated quicklime pansi laimu anaona zamoyo wa ndithu kuchuluka kwa kutentha. Mogwirizana ndi malonda molingana ndi pawiri ili pa otsika kutentha (m'munsimu yozizira koopsa) musaumitse mwabata ndi bwino mphamvu mfundo monga mmene chilengedwe kupereka mofulumira kutentha kuchotsa ndi kuchepetsa nkhawa matenthedwe. Ndi ubwino awa amapanga ntchito zosiyanasiyana CaO mu zomangamanga.

Momwe apamwamba konkire ndi matope kasakaniza?

Pamene hydrated oipa quicklime pansi laimu zotsatira zabwino zitheka akamaziwononga. Choyamba, osakaniza ayenera kukhala zabwino umapezeka. M'pofunikanso kugwilizana ena chiŵerengero ya laimu ndi madzi. Mu ndondomeko ya kuumitsa chofunika akadakwanitsira kutentha kuchotsa iyenera kugwiritsidwa ntchito kapena njira zina kuti salola reheating oipa concretes kapena njira kutentha zomwe zingachititse kwambiri evaporation cha chinyezi (makamaka pa otentha). M'pofunikanso kuchotsa oyambitsa osakaniza pa siteji zina za ndondomeko laimu hydration.

Yosungirako ndi mtengo

Price laimu quicklime zimadalira zosiyanasiyana, ndi mtundu ndi kuchuluka imene zinthu zimenezo. Mwachitsanzo, mtengo wa thumba ndi ku rubles 300-400, ndi tani - kuchokera 8-10 zikwi rubles .. Mankhwala yosungirako ali malo ndi potsegula makina ndi katundu. Kutalika kwa pawiri sayenera yaitali kuposa zisanu masiku khumi (kupewa carbonization ndi hydration wa okusayidi kashiamu). Ogula laimu kapena quicklime apezeka Grinded anatumiza muli, zikwama kapena ngolo bituminous okonzekera mayendedwe ake, kapena magalimoto simenti. Bagging zachitika ntchito mayunitsi zamakono ndi shaker. The mankhwala bagged ziyenera kusungidwa salinso kuposa masiku khumi ndi asanu.
