Quicklime. Quicklime bundu kuvakwa. kunyoresa

Kusvikira panguva iyoyo, mhepo madota rokuvaka raishandiswa chete dziri slaked. I. Smirnov ari thirties pfungwa kushandisa zvinhu zvakasiyana. Iye, uye gare gare Osip BV akaratidza kuti pasi zvimwe zvinhu, hydration koukukutu mashoko anogona kuitika. Izvi zvakafanana koukukutu Portland simende kana gypsum.

Vhuṱanzi

Lime - zvakajairika munyika pfungwa, tichibatanidza conditionally vachiridzira zvigadzirwa (kubudiswa uye gare gare) nesuko, reraimu nezvimwe carbonate matombo. Kupatsanura rinoitwa maererano makemikari anoumba. Kazhinji, shoko "madota" chinorehwa slaked madota ayo maitiro chigadzirwa nemvura. Izvi zvinhu zvinogona woupfu, pasi chimiro kana pabvunzo. Formula kupiswa madota - Cao. remubatanidzwa uyu calcination rakavapo yokucheka mapuranga, umo karusiyamu oxide anoita somunhu inokosha namakemikari zvinoriumba. Ndiye achishingaira zvaanoita nemvura. Somugumisiro ari hydration pakati slaked kwesuko vakaumba - Ca (OH) _2.

kupatsanura

Maererano makemikari anoumba musanganiswa chakaparadzaniswa mhepo (kunyanya rinoumbwa oxides ose magnesium uye calcium yakawanda) uye hydrate (ine yakawanda simbi oxides, aruminiyamu, nesilicon). In indasitiri, akashandisa mukanyiwa madota uye quicklime kuvakwa upfu. The yokupedzisira zvakare rakakamurwa mhando mbiri. First - madota pasi quicklime. Chechipiri mhando rinobudiswa nokushandisa rinokosha rwokugadzira. Kudzima nzira magnesia, karusiyamu madota uye dolomitic kushandisa shoma mvura vakawana slaked madota (hydrated madota). Kune mamwe marudzi. Izvi zvinosanganisira, zvikurukuru, vanosanganisira perchloric, uye pasoda-lime.

kugadzirwa

Kugadzirwa madota pakuvaka vachishandisa dzinongoitika calcium magnesium marudzi. Ivo kunyanya inosanganisira carbonate calcium uye magnesium. In sezvamunoita kwavo chinosanganisirawo That uye jecha admixtures. Munguva chafariz kugadzira (by kudziyisa) muvira kuti tembiricha kuti 800 kusvika 1200 madhigirii karusiyamu-magnesium matombo kutanga anoora. Somugumisiro izvi zvakaunza magnesium oxide (MgO) uye calcium yakawanda (Cao) uye carbon dioxide.

Mabikirwo hwokubereka yakaisvonaka vachikuya musanganiswa

Lime pasi quicklime yaunganidzwa vachikuya musanganiswa ari kwakajairika bhora zvigayo. Basa ravo rinoitwa munyika namahwindo kutenderera pamwe asiyanise munhu inodiwa PARTICIPLE saizi separator. Mune zvimwe zviitiko, chikwata anoiswa mukati separators maviri akatevedzana. Izvi zvinooneka anowedzera yauinayo. To musi, mibvunzo pulverized madota insufficiently yakatanga. The kusarudzwa kwacho musina zvigayo nematunhu zvakafanira kufunga zvikurukuru mwero roasting emashoko (zvakasimba, svikiro kana myagkoobozhzhenny chigadzirwa). Iva nechokwadi kufungawo kuvapo kurukutika, unburned kabhoni, kuvapo nezvishoma. Zvakasimba uye sredneobozhzhennuyu Lime nani muchikuya, kuita pamusoro wayo PARTICIPLE abrasion nezvainoita. Izvi ndizvo zvinoitika bhora zvigayo. Zvinofanira kucherechedzwa kuti katsika zvakasimba inoramba kuti aggregation kunoda pfupi zvigayo uye nokukurumidza kubviswa kubva zvachose kurema musanganiswa anotema wakanaka zvikamu zviduku, uyewo nokushandisa nzira dzinoderedza aggregation.

Kushandiswa quicklime uye zvaro

Zvinhu izvi zvinowanzoshandiswa siyana pazvinoitwa kwevanhu. Vatengi pakukura zvinosanganisira: ferrous simbi, kurima, shuga, zvemakemikari, pulp nebepa indasitiri. Cao uye kushandiswa pakuvaka indasitiri. Zvikuru kukosha ndiyo mukomboni iri zvakatipoteredza. Lime rinoshandiswa kuti kubviswa nesarufa oxide flue gasi. Mukomboni anokwanisawo kupfavisa mvura uye precipitate chipo mairi Organic zvinhu uye zvigadzirwa. Uyezve, kushandisa anokurumidza kwesuko zvinopa dzinongoitika neutralizing acidic uye wastewater. Mune zvokurima, kana kubatana nevhu remubatanidzwa acidity anobvisa zvinokuvadza chirimwa miti. Quicklime Anopfumisa ivhu karusiyamu. Izvi anowedzera workability dzenyika, Inowedzera kuti kuora kuti manyowa. Panguva iyoyo riri achidzikisa kudiwa senitrogen fetiraiza kushanda huru mishonga. The hydrated muvhenganiswa rinoshandiswa yehuku uye zvipfuwo kuti dzichifura. Saka kubvisa kushaya calcium mune zvokudya. Uyezve, mukomboni inoshandiswa kuvandudza mamiriro ezvinhu pautano apo pakuchengeta uye ruminant nezvipfuwo. In makemikari indasitiri hydrated madota uye adsorbents inoshandiswa achigadzirira fluoride uye calcium yakawanda hydrochloride. Muna petrochemical indasitiri mukomboni neutralizes ari iine acid sludge uye anoita somunhu reagent kunyanya inorganic uye makemikari kwetunhu. Lime zvinowanzodavirwa kushandiswa kuvaka. Izvi imhaka kumusoro zvinhu zvakatipoteredza. Musanganiswa yaishandiswa kwegadziriro binders, concretes uye mumaturi, nokuti kugadzirwa chivakwa zvigadzirwa.

Quicklime micronized. zvakwakanakira

Quicklime, sezvo kare ambotaurwa, rinoshandiswa zvaAtemisi concretes uye mumaturi. remubatanidzwa ichi ane nhamba zvakanakira. Zvikurukuru, tichienzanisa hydrated madota ari muchimiro mukanyiwa kana upfu musanganiswa dzakarukwa zvakanaka yakakamurwa mashizha hapana tsvina. With zvose zvinoumba ayo panguva nokuomesa anoshandiswa zvikuru zvakanaka. Lime pasi quicklime iri shoma mvura kudiwa. Uyezve, ayo chaiyo pamusoro nzvimbo kuri yekudyidzana zvishoma. Panyaya iyi, "workability" kana kongiri kwakavakirwa Cao mhinduro vakawana panguva kwakaderedza Vhoriyamu mvura. Kuderedza mvura chinodiwa kongiri uye mumaturi kunonatsiridza kutsiga pavanenge kuomesa. Pamusoro hydration mu atogadzirira wemisanganiswa kwesuko anosunga zvakawanda mvura (pa yezwi hydrate - 32%). Izvi zvinobatsira kuti pakuwana zvibereko concretes uye mumaturi vamatunhu arambe achirema uye simba. In muitiro kuomesa hydrated quicklime pasi madota vakachengeta Kushanduka zvikuru huwandu kupisa. Maererano zvigadzirwa izvi kunobva remubatanidzwa ichi yakaderera (pazasi nechando) kutonhora vanoomesa hwakanyarara uye nani simba netsika, mamiriro zvezvakatipoteredza zvinopa zvakasimba kupisa Kubviswa uye kuderedza chafariz kunetseka. Zviri zvinobatsira izvi kunoita kushandisa paupamhi pamusoro Cao pakuvaka indasitiri.

How kuti yepamusoro kongiri uye dhaka mixes?

Kana hydrated nokuomesa quicklime muvhu madota migumisiro yakanaka zvinogoneka pasi zvimwe ezvinhu. Chekutanga, musanganiswa inofanira kuva yakanaka nokugeda. Zvinokoshawo abvume vamwe reshiyo kwesuko uye mvura. In muitiro kuomesa zvaida optimum kupisa kubviswa anofanira kutevedzerwa kana dzimwe nzira kuti hatibvumiri reheating nokuomesa concretes kana mhinduro kutonhora chingakonzera kwakanyanya kwemvura ine mwando (kunyanya panguva kufashaira). Zvinokoshawo kugumiswa anonyandura musanganiswa pane imwe padanho kwesuko hydration kwacho.

Storage uye mutengo

Price madota quicklime kunobva siyana, mhando uye uwandu umo mashoko acho kunodiwa. Somuenzaniso, mari bhegi iri kubva 300-400 rubles, uye peche - kubva 8-10 zviuru rubles .. Product okuchengetera riri dzokuchengetera pamwe michini vachizvitakudza uye vachidzikisa. Ya mukomboni hakufaniri mazuva anopfuura namashanu gumi (kudzivisa carbonization uye hydration calcium oxide). Consumer madota kana quicklime nemavhinga Grinded akatuma mumidziyo, mabhegi kana bituminous ngoro akashongedzerwa ayo chokufambisa, kana mune simende motokari. Bagging zvinoitwa kushandisa zviyero ano pamwe shaker. The bagged chigadzirwa inofanira kuchengetwa asisiri kupfuura mazuva gumi nemashanu.
