Siv:
Kev ua liaj ua teb siv: raw khoom ntawm phosphate fertilizer thiab pub cov as-ham
Kev lag luam siv: chemical raw khoom
1. Tiv thaiv cov hlau los ntawm corrosion
2.Mixed nrog nitric acid ua tshuaj polishing tus neeg saib xyuas kom txhim kho qhov chaw tiav ntawm cov hlau
3.Material ntawm phosphatide uas yog siv los tsim cov khoom siv ntxhua khaub ncaws thiab tshuaj tua kab
4.Kev tsim cov phosphorus uas muaj cov ntaub ntawv flameretardant.
Khoom noj khoom haus additives siv: acidic flavoring, Poov Nutri-ents, xws li coca-cola.
Kev siv kho mob: los tsim cov tshuaj uas muaj phos-phorus, xws li Na 2 Glycerophosphat
Khoom noj khoom haus thiab qib qib phosphoric acid yog ob yam tshuaj tseem ceeb uas tau siv dav hauv ntau yam. Dab tsi yog qhov sib txawv ntawm lawv thaum siv, thiab koj nrhiav tau qhov chaw zoo dua li cas.
1. Khoom noj khoom haus qib phosphoric acid
Khoom noj khoom haus qib phosphoric acid yog xim tsis muaj xim, pob tshab los yog xim daj me ntsis nrog cov acidity thiab adsorption zog. Nws tuaj yeem cuam tshuam nrog cov hlau ions los tsim cov phosphates insoluble, thiab yog li siv dav hauvzaub movkev lag luam. ruaj khov zoo, tsis muaj mob rau tib neeg lub cev.
2. Muaj qib phosphoric acid
Industrial qib phosphoric acid yog corrosive thiab acidic. Lub purity ntawm qib industrial phosphoric acid yog qhov tsawg, tab sis nws muaj kev ua haujlwm zoo catalytic thiab ruaj khov, thiab tau siv dav hauv kev lag luam xws li chemical engineering, metallurgy, thiab dej kho.
Nyob rau hauv tus txheej txheem ntawm kev siv, Scope ntawm daim ntawv thov ntawm ob kuj tsis zoo ib yam. Piv txwv li, cov zaub mov qib phosphoric acid yog cov khoom siv acidity uas tuaj yeem txhim kho cov acidity ntawm cov zaub mov thiab txhim kho nws saj. Piv txwv li, ntxiv qhov tsim nyog ntawm cov zaub mov qib phosphoric acid rau cov khoom xws li dej haus, khoom qab zib, thiab condiments tuaj yeem ua rau lawv muaj kua qaub.
Thib ob, nws tuaj yeem ua qhov tsis tuaj yeem tswj xyuas qhov tshiab thiab saj ntawm cov zaub mov. Ntxiv cov zaub mov qib phosphoric acid rau cov khoom xws li yogurt thiab jam tuaj yeem tiv thaiv cov zaub mov lwj. Nws kuj tuaj yeem ua rau cov hlau ions hauv cov khoom noj los tsim cov phosphates insoluble, yog li txo cov ntsiab lus ntawm cov hlau hnyav hauv cov zaub mov.
Muaj qib phosphoric acid yog siv dav hauv kev lag luam tshuaj, xws li hauv kev tsim cov phosphate.chiv, tshuaj tua kab, dyes, thiab lwm yam. Tsis tas li ntawd, muaj qib phosphoric acid kuj tseem siv tau los ua cov nplaim hluav taws, cov dej dehydrating, catalyst, thiab lwm yam.
Nws ua lub luag haujlwm tseem ceeb hauv thaj chaw metallurgical, xws li hauv polishing, xeb tshem tawm, acid ntxuav, thiab lwm yam ntawm cov hlau. Tsis tas li ntawd, kev lag luam qib phosphoric acid kuj tuaj yeem siv los rho tawm cov hlau, xws li txhuas, tin, thiab lwm yam los ntawm cov roj teeb pov tseg. Nws muaj ntau yam kev siv hauv kev kho dej, uas tuaj yeem tshem tawm cov khib nyiab pov tseg, sediments, thiab cov kab mob hauv dej, thiab txhim kho cov dej zoo.
Nrog rau kev nthuav dav ntxiv ntawm daim ntawv thov kev lag luam ntawm cov khoom noj thiab cov qib phosphoric acid, kev lag luam xav tau nce xyoo los ntawm xyoo. Kev lag luam xav tau rau qib kev lag luam phosphoric acid muaj kev cia siab dav, thiab kev nce qib ntawm kev noj qab haus huv, ntsuab, thiab cov zaub mov zoo kuj tau muab sijhawm tshiab rau kev lag luam zaub mov qib phosphoric acid.
Hauv cov ntsiab lus, cov zaub mov thiab qib qib phosphoric acid muaj cov ntawv thov dav dav hauv ntau qhov chaw. Tawm tsam keeb kwm yav dhau los ntawm kev xav tau ntawm kev lag luam, cov lag luam yuav tsum tau hloov kho tshiab thiab txhim kho kom zoo kom tau raws li kev xav tau ntawm kev lag luam! Yog xav tau, thov koj xav tiv tauj thiab sib tham.
