Qee lub sij hawm, txhawm rau txo qhov kub ntawm cov khoom, ntsev ntxiv rau hauv dej khov lossis daus [1]. Niaj hnub no, kev tsim khoom ntawm ntau hom dej khov (cov dej khov khov, cov dej khov khov, cov dej khov slurry, thiab lwm yam) tau ua. Lub tshuab dej khov slurry tau tsim nyob rau hauv Russia txog 80 xyoo dhau los.
Ib qho dej khov slurry siv rau dab tsi?
Ice slurry kuj tseem siv tau ua ib qho txias cia nruab nrabhauv ntau lub nkoj uas tsis muaj cov tub yees ua hauv lub tshuab xws li dej khov slurry txias trolleys, tsheb thauj khoom lossis nkoj nuv ntses. Kev ntim khoom, kev nuv ntses, nrog rau nws daim ntawv thov tshiab tshiab rau kev tiv thaiv lub cev txias thaum muaj xwm txheej ceev thiab kev phais.
Yuav ua li cas yog slurry ice ua?
Slurry ice yog tsim dhau ntawm cov txheej txheem ntawm kev tsim cov dej khov nab kuab nyob rau hauv cov kua … Nyob rau hauv no heat exchangers steel particles circulate with the fluid mechanically remove the crystals from the surface. Ntawm qhov hluav taws xob steel hais thiab slurry ice yog sib cais.
Qhov kub ntawm cov dej khov slurry yog dab tsi?
Ice slurry yog tsim nyob rau hauv qhov kub thiab txias nruab nrab ntawm -10 txog -4 °C. Ib qho kev sib piv ntawm evaporation kub rau Sab Nraud Melt Ice-on-Coil thiab cov dej khov slurry txuam nrog ua. Cov txheej txheem dej khov ib txwm ua rau dej txias ntawm 0 txog 2 ° C.
Dab tsi yog qhov sib xyaw slurry?
Slurry, dej sib tov lossis tshem tawm ntawm cov teeb meem insoluble. Hauv kev tsim khoom ntawm portland cement, sib tov ntawm cov khoom siv raw nrog dej yog hu ua slurry.

Yuav thaiv cov dej khov txias rau kuv lub pas dej li cas?
Ice Ice kuj txias lub pas dej, tab sis nws tsis yog ib txoj hauv kev ua kom txias pas dej-raws li nws yuav siv sij hawm ib qho. Cov dej khov ntau dhau thiab qhov kev hloov pauv tsuas yog ib ntus xwb. Raws li ib tsab xov xwm hauv Wall Street Journal, nws yuav siv 8,750 phaus dej khov kom txo cov dej kub ntawm 20,000 nkas loos pas dej los ntawm 10 degrees … dej txias npaum li cas rau lub pas dej?
Vim li cas cov dej khov thiab qhov dej khov zoo ib yam?
Thaum txias, cov khoom hauv cov kua poob zog, tsis txhob txav mus los thiab nyob rau hauv qhov chaw ruaj khov, ua kom muaj zog. Freezing tshwm sim ntawm qhov kub ib yam li melting, li no, lub melting point thiab khov point ntawm ib yam khoom yog kub tib yam .
Puas yog dej khov ntab rau ntawm cov dej ua kua?
Ntseeg nws los tsis yog, dej khov tiag tiag li 9% tsawg dua dej. Vim dej hnyav dua, nws hloov cov dej khov sib dua, ua rau cov dej khov ntws mus rau saum . Puas yog cov dej khov nab kuab lossis ntab hauv dej? Kev piav qhia: Rau feem ntau cov khoom, cov khoom (khov) theem yog qhov ntom ntom tshaj plaws thiab yuav tog hauv cov kua theem.
Cov txheej txheem twg ntawm cov kwj dej kais dej nqus cov khoom noj?
Mucosa. Lub mucosa, tsim los ntawm cov kab mob yooj yim epithelium, yog txheej sab hauv ntawm txoj hnyuv (GI) ib puag ncig. Nws yog qhov nqus thiab secretory txheej ntawm GI ib puag ncig . txheej dab tsi absorbs as-ham? Lub luag haujlwm tseem ceeb ntawm txoj hnyuv meyog qhov nqus ntawm cov as-ham thiab cov zaub mov muaj nyob hauv cov zaub mov.
Lub tsev dej khov tau tsim thaum twg?
1780 BC sau txog kev tsim lub tsev dej khov los ntawm Zimri-Lim, tus huab tais ntawm Mari, nyob rau sab qaum teb Mesopotamian lub nroog Terqa, "uas tsis tau muaj vaj ntxwv ua ntej. " Hauv Suav teb, archaeologists tau pom qhov seem ntawm cov dej khov nab kuab los ntawm lub xyoo pua 7 BC, thiab cov ntaub ntawv qhia tias cov no tau siv ua ntej 1100 BC .
