cov khoom siv tshuaj lom neeg:
calcium hydroxide (calcium hydroxide), ib qho inorganic compound nrog cov tshuaj mis Ca(OH)2, feem ntau hu ua slaked lime lossis hydrated lime. Nws yog ib qho khoom dawb zoo li hmoov. Thaum ntxiv dej, nws tsim ob txheej. Txheej sab saud ntawm cov kua dej hu ua dej ntshiab lime, thiab txheej sab hauv qab ntawm cov tshuaj no hu ua lime milk lossis lime slurry. Cov kua ntshiab ntawm txheej sab saud, dej lime, siv tau los kuaj carbon dioxide, thaum cov kua turbid ntawm txheej sab hauv qab, lime milk, yog cov khoom siv hauv tsev. Qhov solubility ntawm calcium hydroxide txo qis nrog qhov kub nce. Nws tsis yaj hauv cawv tab sis yaj hauv cov ntsev ammonium thiab glycerol. Nws tuaj yeem cuam tshuam nrog cov kua qaub los tsim cov ntsev calcium sib xws. Ntawm 580 ℃, nws decomposes rau hauv calcium oxide thiab dej.

Kev Siv
Siv rau hauv kev tsim cov hmoov dawb, cov tshuaj ua kom dej mos, cov tshuaj tua kab mob hauv dej thiab cov tshuaj ua kom dej ntshiab, nrog rau hauv kev lag luam kev tsim kho, thiab lwm yam.
Siv rau hauv kev lag luam tshuaj. Nws tuaj yeem siv ua cov khoom ntxiv rau hauv kev lag luam roj hmab thiab roj av. Thaum siv rau hauv cov roj nplua nyeem, nws tuaj yeem tiv thaiv kev coking, kev tso cov sludge, neutralize thiab tiv thaiv kev xeb. Nws kuj tseem tuaj yeem siv ua cov dej mos, tshuaj tua kab mob, antacid, thiab lwm yam.
Nws yog siv los ua ib qho analytical reagent, ib qho carbon dioxide absorber, thiab tseem siv rau hauv organic synthesis
Nws yog siv rau kev ua cov hmoov dawb, cov tshuaj ua kom dej mos, cov tshuaj depilators, cov tshuaj tua kab mob, antacids, astringents thiab ntau yam calcium ntsev.
Sim cov pa roj carbon dioxide, kev nqus roj. Tshem cov plaub hau tawv, tswj kab tsuag, kho dej.
Ntim thiab Xa Khoom
25KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
