Quicklime. Quicklime ukwakhiwa Semali. isicelo

Kuze kube yileso sikhathi, umoya lime ekwakheni yasetshenziselwa kuphela ngesimo slaked. I. Smirnov ku namathathu banesifo esibi wasikisela ukusebenzisa impahla ezahlukene. Yena, futhi kamuva Osip BV wabonisa ukuthi ngaphansi kwezimo ezithile, hydration ukuqina impahla singenzeka. Le nqubo iyafana ukuqina Portland usimende noma Gypsum.

ulwazi olujwayelekile

Lime - kuyinto evamile umqondo jikelele, ngokuhlanganisa imikhiqizo kunemibandela kokudubula (kusebenziswe futhi kamuva) wokulinganisa, limestone nye shushuzela carbonate. Ukwahlukanisa Kwenziwa ngokuvumelana Ukwakheka kwamakhemikhali. Ngokuvamile, elithi "lime" lizama lime slaked kanye yokusabela umkhiqizo wawo ngamanzi. Le nto ingase oluyimpuphu, ifomu phansi noma isivivinyo. Formula wokushiswa lime - cao. Le ngxube iwumkhiqizo calcination of imishini yokusaha izingodo, lapho i-calcium oxide uba eziyisisekelo chemical ingxenye. He is ngenkuthalo ihlangana emanzini. Ngenxa yalokho we hydration lime slaked kwakhiwa - Ca (OH) _2.

ngezigaba

Ngokusho ukwakheka kwamakhemikhali ingxube kwaba emoyeni ehlukanisiwe (ikakhulu ehlanganisa oxides magnesium ne-calcium) kanye hydrate (equkethe esiningi yensimbi oxides, aluminium, ne-silicon). Ngo umkhakha, wasebenzisa yinhlama lime nokwakhiwa quicklime powder. Lesi sakamuva nayo lahlukaniswa izinhlobo. Okokuqala - lime phansi quicklime. Uhlobo lwesibili ezivezwa isicelo ubuchwepheshe ekhethekile. Ningamcimi indlela magnesia, i-calcium lime futhi dolomitic usebenzisa okulinganiselwe lokuhlanzeka kwamanzi atholakala lime slaked (hydrated lime). Zikhona nezinye izinhlobo. Lezi zihlanganisa, ngokukhethekile, zihlanganisa perchloric, soda-lime.

ukukhiqizwa

Manufactured lime ngenxa ukwakhiwa usebenzisa zemvelo calcium ne-magnesium zilwane. Bahlanganyela zihlanganisa carbonate-calcium ne-magnesium. Ngo Ukwakheka kwabo kukhona Clays nesihlabathi admixtures. Phakathi kwenqubo ezishisayo (by Ukushisa) esithandweni lokushisa 800 kuya 1200 degrees calcium-magnesium amatshe aqala ukubola. Ngenxa yalokho yale nqubo ekhiqizwa magnesium oxide (MgO) ne-calcium (CAO) ne-carbon dioxide.

Ubuchwepheshe ngokukhiqiza esihle ukugaya ingxube

Lime phansi quicklime etholwe ukugaya ngxube ezivamile ibhola Mills. Umsebenzi wabo wenziwa umjikelezo avaliwe evelela a obudingekayo kuyizinhlayiyana isihlukanisi. Kwezinye izimo, iyunithi ibekwa separators ezimbili chungechunge. Lokhu kakhulu kwandisa umkhiqizo. Kuze kube manje, imibuzo lime ziyacolwa insufficiently athuthukile. Uhlelo lokukhethwa ukugaya ematsheni okugaya nelezifunda ezidingekayo cabanga ngokuyinhloko degree of yokuwugazinga we impahla (kakhulu, medium noma umkhiqizo myagkoobozhzhenny). Qiniseka ukuba acabangele khona nokutubeka, carbon unburned, khona ukudla okuqinile. Kakhulu futhi sredneobozhzhennuyu lime kangcono ugaye, ukulalela kuyizinhlayiyana yayo nemihuzuko kanye nomthelela. Yilokhu okwenzekayo e ibhola Mills. Kufanele kuqashelwe ukuthi ukuthambekela izinhlayiya esiqinile wokuhlanganisa kudinga Izigayo iDemo nokuqeda okusheshayo kusukela isisindo ingqikithi ingxube ukugawulwa amafraktjhini emihle, kanye nokusetshenziswa izindlela ezinciphisa wokuhlanganisa.

Ukusetshenziswa quicklime futhi imikhiqizo yayo

Le nto kabanzi kuyo yonke imikhakha yomsebenzi womuntu. Amakhasimende ngobukhulu zihlanganisa: yokusansimbi ayoni, ezolimo, ushukela, amakhemikhali, uginindela umkhakha ephepheni. Cao futhi lisetshenziswe embonini yezokwakha. Okubaluleke kakhulu yiyona kwakwakhe imvelo. Lime isetshenziselwa ukususwa sulphur oxide flue igesi. Egcekeni unamandla ukuthambisa amanzi kanye kwenze samanje therein izinto eziphilayo kanye nemikhiqizo. Ngaphezu kwalokho, ukusetshenziswa lime ngokushesha inikeza zokuyithena zemvelo esidi lamanzi anokugcola. Kwezolimo, uma nabo nenhlabathi kwakwakhe asidi aqede yingozi izitshalo. Quicklime kuthuthukisa umhlabathi calcium. Lokhu kwandisa workability zomhlaba, ngesivinini ukubola humus. Ngesikhathi esifanayo it is ngokunciphisa isidingo sokusebenzisa i-nitrogen Umanyolo isicelo ngemithamo ezinkulu. Ingxube hydrated isetshenziswa yenkukhu nemfuyo ekunikezeni ukudla. ekuqedeni Ngakho ukuntuleka calcium ekudleni. Ngaphezu kwalokho, lesi sithako esetshenziselwa ngcono izimo zezempilo jikelele ngenkathi ugcina futhi ukuzalela imfuyo. Esikhathini umkhakha chemical hydrated lime futhi adsorbents esetshenziselwa ukulungiswa fluoride ne-calcium hydrochloride. Esikhathini Petrochemical umkhakha kwakwakhe neutralizes sludge acid futhi uba reagent ikakhulukazi wezinto ezingaphili futhi organic zamagama. Lime kabanzi lisetshenziswe ukwakhiwa. Lokhu kungenxa okusezingeni eliphezulu impahla kwemvelo. Ingxube lalisetshenziswa ukulungiswa binders, Concretes futhi ezigqulweni, ukwenziwa imikhiqizo wokwakha.

Quicklime micronized. izinzuzo

Quicklime, njengoba sekushiwo ngenhla, isetshenziswa womshini Concretes futhi izigqulo. Le ngxube has eziningi eziwusizo. Ikakhulukazi, uma kuqhathaniswa ngomcako hydrated ngesimo inhlama noma ingxube powder amahlamvu fake ihlukaniswe kungekho imfucuza. Nge zonke izingxenye zalo phakathi ukuqina asetshenziswa kakhulu kahle. Lime phansi quicklime ingaphansi kwamanzi funa. Ngaphezu kwalokho, i-surface area yayo eqondile futhi kubonisa ukuthi mancane. Kule ndaba, "workability" noma ukhonkolo esekelwe isixazululo Cao etholwe ezingeni elilinganiselwe ukuncipha kwamanzi. Ukunciphisa amanzi adingwa ngokhonkolo futhi izigqulo kuthuthukisa azinze ngesikhathi lukhuni. Lapho hydration e Izingxube kakade walungisa lime sibopha amanzi ngaphezulu (at kwathatha hydrate - 32%). Lokhu kunomthelela ukuthola imikhiqizo ye Concretes futhi izigqulo high density namandla. Ngo inqubo lukhuni le hydrated quicklime phansi lime waphawula ukuvela eside inani ukushisa. Ngokuqondene nalokhu imikhiqizo ezisuselwa kulesi kwakwakhe at ongaphakeme (ngaphansi kwezinga-qhwa) okushisa lukhuni ezikhathini ezinzima futhi babe ngcono amagugu amandla, njengoba isimo ahlinzeke ukushisa okusheshayo ukususwa kanye nokunciphisa ekucindezelekeni ezishisayo. Kuyinto lezi zinzuzo kwenza ukusetshenziswa ebanzi Cao embonini yezokwakha.

Kanjani ukuze uthole eliphezulu ukhonkolo nodaka amamiksi?

Lapho amanzi amaningi ukuqina quicklime phansi lime imiphumela emihle zingenzeka ngaphansi kwezimo ezithile. Okokuqala, ingxube kufanele kube ukugaya okuhle. Kuyadingeka ukuhambisana isilinganiso esithile lime namanzi. Ngo inqubo lukhuni edingekayo elikhulu ukushisa ukususwa okumele asetshenziswe noma yiziphi ezinye izindlela ukuthi ungavumeli reheating ukuqina Concretes noma izixazululo okushisa kungabangela ukuhwamuka okukhulu umswakama (ikakhulukazi phakathi abilayo). Libuye ekunqanyulweni ezibalulekile sibhebhezela ingxube esikhathini esithile inqubo lime hydration.

Ukugcinwa Kwazo Ngenjongo izindleko

Inani lime quicklime kuncike ezihlukahlukene, uhlobo kanye nenani lapho impahla edingekayo. Ngokwesibonelo, izindleko isikhwama ruble 300-400, futhi ton - kusukela ama-ruble ayizigidi 8-10 .. isitoreji Mkhiqizo emafektri nge ukulayisha ngomshini futhi athula. Ubude kwakwakhe akufanele kube izinsuku eyevile kwemihlanu-eziyishumi (ukugwema carbonization futhi hydration-calcium oxide). Umthengi lime noma quicklime izigaxa Grinded wathumela izigubhu, izikhwama noma izinqola bituminous ahlomele zokuthutha yayo, noma usimende amaloli. Bagging kwenziwa ngokusebenzisa amayunithi esine shaker. Umkhiqizo bagged kufanele agcinwe ayisekho kuka izinsuku eziyishumi nanhlanu.
