Quicklime. ukwakhiwa Isixa Quicklime. isicelo

De kube lelo xesha, umoya ikalika ekwakhiweni lalisetyenziswa kuphela ngohlobo islaked. I. Smirnov kwi banesifo wacebisa ukuba usebenzise izinto ezahlukeneyo. Yena, yaye kamva Osip BV wabonisa ukuba phantsi kweemeko ezithile, ukuxovwa lukhuni i eziphathekayo zenzeke. Le nkqubo iyafana lukhuni ePortland zesamente okanye gypsum.

ulwazi jikelele

Ikalika - kuxhaphakile ehlabathini ingqiqo ehlabathini, edibanisa iimveliso kwemiqathango zokudubula (processing kunye kamva) itshokhwe, lekalika kunye nezinye nasemaweni carbonate. Classification yenziwa ngokwe nokwakheka imichiza. Ngokuqhelekileyo, igama elithi "ikalika" lwenzelwe islaked kunye nemveliso yayo asabela ngamanzi. Le elayibrari ukuba olungumgubo, uhlobo emhlabeni okanye uvavanyo. Formula lime anyukayo - cao. Le umchiza yimveliso calcination of amaplanga, apho calcium oxide lisebenza njengecandelo esisiseko imichiza. Nguye ngenkuthalo idityaniswe namanzi. Ngenxa yoko le ukuxovwa kwekalika islaked kwakhiwa - Ca (OH) _2.

ngezigaba

Ngokutsho umchiza ukwakhiwa le umxube umoya eyahlukileyo (ubukhulu becala eyenziwa oxides magnesium kunye calcium) kunye ukuphilisa (equlathe izixa ezikhulu oxides yentsimbi, i-aluminiyamu, kunye lesilicon). Kushishino, wasebenzisa esisixa ikalika kunye nomgubo ukwakhiwa quicklime. Le yokugqibela kwakhona zohlulwa ngokwendidi ezimbini. Okokuqala - lime quicklime emhlabeni. Uhlobo lwesibini yaveliswa ngokusebenzisa ubuchwepheshe okhethekileyo. Ukucima indlela magnesia, calcium ikalika dolomitic usebenzisa imali encinane wamanzi afunyenwe islaked (ikalika hydrated). Kukho nezinye iindidi. Ezi ziquka, ingakumbi, iquka perchloric, kunye nesoda-lime.

production

lime bokwenziwa ukwakhiwa usebenzisa calcium nezinki iintlobo zendalo. Bona ikakhulu ziquka carbonate calcium nezinki. Kumafa yabo ikwaquka clays kunye admixtures nesanti. Ngexesha processing thermal (ngokutshisa) eziko ukuya kwiqondo lobushushu 800 ukuya 1200 degrees calcium-wemagniziyam rocks uqalise ukubola. Ngenxa yale nkqubo wavelisa wemagniziyam oxide (MgO) kunye calcium (cao) kunye carbon dioxide.

Ithekhnoloji ngokwenza ocoliweyo ukugaya umxube

quicklime komhlaba Ikalika ezifunyenwe yi besila umxube ngendlela eqhelekileyo ematyeni ibhola. umsebenzi wabo wenziwa kumjikelo evaliweyo ukucalula ukuba umahluli ubungakanani yamasuntswana efunekayo. Kwezinye iimeko, le yunithi sibekwe sahluli ezimbini series. Oku kwandisa kakhulu imveliso. Ukuza kuthi ga ngoku, imibuzo ungacolwanga kwekalika ngokwaneleyo kuphuhliswa. Inkqubo yokukhetha esivikivayo Mills kunye neziphaluka kuyimfuneko ukuba siqwalasele kakhulu iqondo kaJohn zokufunda (ngamandla, eliphakathi okanye imveliso myagkoobozhzhenny). Qiniseka ukuba bakuthathele ingqalelo phambi nokudinwa, icarbon isigodo, ubukho eziqinileyo. Ngamandla kwaye sredneobozhzhennuyu ikalika ngcono athwala amatye okusila, alunywe lingonakali yayo yamasuntswana kunye nempembelelo. Oku kwenzeka ntoni ematyeni ibhola. Kufuneka kuqatshelwe ukuba isiqhelo kwamasuntswana eqinileyo udibaniso kufuna ematyeni ezifutshane ukuphelisa ngokukhawuleza ukusuka ubunzima lilonke umxube gawula amaqhezu ocoliweyo, kwakunye nokusetyenziswa iindlela zokunciphisa udibaniso.

Ukusetyenziswa quicklime kunye nemveliso yayo

Le nto sisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo zezinto ezenziwa luluntu. Le abathengi inkulu ziquka: yokunyibilikisa isinyithi ayoni, ezolimo, iswekile, imichiza, yintlama noshishino iphepha. Cao kunye esetyenziswa kwishishini lokwakha. Okubaluleke kakhulu umchiza kokusingqongileyo. Ikalika isetyenziselwa ukususwa igesi sulphur oxide flue. Umchiza ubuye abe nakho ukuthambisa amanzi kwaye kwenze langoku kuyo izinto eziphilayo kunye nemveliso. Ngaphezu koko, ukusetyenziswa kwekalika ekhawulezayo inika lwaze yendalo esidi amdaka. Kwezolimo, xa wadibana emihlabeni compound iasidi akubikho yingozi izityalo zezityalo. Quicklime elicebisa umhlaba nge calcium. Oku kwandisa workability zomhlaba, ibalekisa ukubola wamatye. Kwangaxeshanye oko kunciphise imfuneko isicelo nitrogen isichumiso ngeedosi ezinkulu. Lo mxube hydrated isetyenziswa iinkukhu kunye nemfuyo wokondla. Ngaloo ukuphelisa ukungabikho ikhalsiyam apha ekutyeni. Ngaphezu koko, umchiza ezisetyenziselwa ukuphucula iimeko zempilo jikelele ngexesha zokugcina lwemfuyo imfuyo. Kushishino yemichiza ye hydrated ikalika adsorbents ezisetyenziselwa yokulungiselela fluoride kunye calcium hydrochloride. Xa compound kushishino petrochemical neutralizes le elitshisiweyo asidi kwaye isebenza reagent ikakhulu ezingaphiliyo kunye organic yokuqaphela. Ikalika ngokubanzi asetyenziswe ekwakheni. Oku kungenxa yokuba izinto eziphakamileyo kwezendalo. Lo mxube yasetyenziswa ekulungiseleleni yokuhlanganisa, concretes kunye mortars, kuba imveliso zezixhobo zokwakha.

Quicklime micronized. buhle

Quicklime, njengokuba sele kukhankanyiwe ngentla, isetyenziswa ekwenziweni concretes kunye mortars. Le umchiza inenani yeenzuzo. Ngokukodwa, xa kuthelekiswa ngekalika hydrated ngohlobo intlama okanye umxube ngumgubo amagqabi ezicukucezwe zancinane akukho inkunkuma. Ekubeni onke amacandelo zalo ngexesha ukuqaqadeka zisetyenziswa ngokufanelekileyo. quicklime komhlaba Ikalika imfuno yamanzi ngaphantsi. Ngaphezu koko, indawo yayo umphezulu ethile nalo kakhulu ngaphantsi. Kule nkalo, "workability" okanye ikhonkrithi ngokusekelwe cao sisombululo zingafumaneka ngexabiso eliphantsi umthamo wamanzi. Ukunciphisa mfuneko ngamanzi eziphathekayo mortars kuphucula uzinzo lwabo ngethuba lukhuni. Phezu ukuxovwa kwimixube esele ilungisiwe lime ubophelela amanzi amaninzi (kwi inguqu ukuphilisa - 32%). Oku kunegalelo ekufumaneni iimveliso concretes kunye mortars of ezixineneyo kunye namandla. Xa inkqubo lukhuni zekalika hydrated emhlabeni quicklime waphawula ngendaleko okukhulu mali ubushushu. Ngokuphathelele oku iimveliso ezisekelwe kule ambaxa kumaqondo obushushu asezantsi (ngezantsi qhwa) lukhuni kwethu kunye namanani engcono amandla, njengokuba iimeko zokusingqongileyo zibonelela ukususwa ubushushu fast kunye nokwehlisa ntshikilelo thermal. Kuyinto ezi zibonelelo yenza ukusetyenziswa ezininzi cao kwishishini lokwakha.

Indlela ukufumana eziphathekayo kunye nodaka nemixube ezikumgangatho ophezulu?

Xa hydrated ukuqaqadeka quicklime ekalika umhlaba iziphumo ezintle zinokwenzeka phantsi kweemeko ezithile. Okokuqala, lo mxube kufuneka lokugaya entle. Kwakhona kuyimfuneko ukuthotyelwa ratio ezithile lime kunye namanzi. Xa inkqubo lukhuni efunekayo zokususa ubushushu elilelona kufuneka isicelo okanye ezinye iindlela musa ukuvumela ayaphola concretes yokuqaqadeka okanye nezisombululo kumaqondo ezinokubangela komphunga kakhulu ukufuma (ingakumbi ngexesha abilayo). Kwakhona ukupheliswa ebalulekileyo ndixoxa umxube kwi kwinqanaba elithile inkqubo yekalika ukuxovwa.

Ukugcinwa neendleko

Ixabiso ekalika quicklime kuxhomekeke uhlobo, uhlobo kunye nemali apho izinto ezifunekayo. Umzekelo, iindleko wengxowa uvela engange 300-400, kunye ton - ukususela 8-10 amawaka engange .. yokugcina imveliso ezikwindawo yokugcina impahla yokulayisha imishini kunye nokothula. Ixesha compound kufuneka ungabi ngaphezu kweentsuku ezintlanu-ezilishumi (ukuphepha carbonization kunye ukuxovwa ngecalcium oxide). lime Consumer okanye quicklime lunamahlwili amhlophe Grinded ithunyelwe kwizikhongozelo, iibhegi okanye iinqwelo bituminous exhobele yokuhamba kwayo, okanye ngeelori isamente. Esakeni kwenziwa ngokusebenzisa iiyunithi yalamaxesha nge isihlukuhli. Le mveliso zifakwe kufuneka igcinwe elingekho ngaphezu kweentsuku ezilishumi elinesihlanu.
