    Khoom Description

    Phosphorous acid yog nyob rau hauv Colorless, pob tshab thiab syrupy kua los yog rhombic crystalline; Phosphorus acid yog tsw thiab saj heev qaub; nws melting point yog 42.35 ℃ thiab thaum rhuab mus rau 300 ℃ phosphorous acid yuav ua rau metaphosphoric acid; nws cov txheeb ze ntom ntom yog 1.834 g / cm3; phosphoric acid yog yooj yim soluble hauv dej thiab daws hauv ethanol; Phosphate acid tuaj yeem ua rau tib neeg tawv nqaij ua rau phlogosis thiab rhuav tshem qhov teeb meem ntawm tib neeg lub cev; phosphorus acid qhia corrosiveness tau rhuab hauv cov hlab ntsha ceramic; phosphate acid tau txais hydroscopicity.
    Kev siv Phosporic Acid:
    Kev kawm qib Phosphoric Acid tuaj yeem siv los tsim ntau yam Phosphates, cov kua dej kho electrolyte lossis cov kua tshuaj kho mob, cov tshuaj khib nyiab refractory nrog phosphoric acid thiab inorganic coheretant.Phosporic acid kuj yog siv los ua cov catalyst, ziab thiab ntxuav. Hauv kev lag luam txheej txheej phosphoric acid yog siv los ua xeb-pov thawj txheej rau hlau; Raws li tus neeg saib xyuas cov kua qaub thiab cov khoom noj khoom haus rau cov poov xab zaub mov qib phosphoric acid tuaj yeem siv rau cov khoom qab zib, cov kaus poom zaub mov thiab cov dej qab zib, thiab siv rau hauv wine brewery ua cov khoom noj rau cov poov xab los tiv thaiv kev loj hlob ntawm cov kab mob tsis zoo.

    Daim ntawv thov

    Phosphoric Acidused hauv kev tshem tawm cov plua plav tawm ntawm qhov chaw hlau Siv los ua xeb hloov pauv los ntawm kev coj nws ncaj qha nrog cov hlau xeb, lossis cov cuab yeej hlau thiab lwm qhov chaw uas xeb. Nws muaj txiaj ntsig zoo hauv kev ntxuav cov pob zeb hauv av, cement nous smears thiab cov dej tawv stains. Siv rau acidify cov zaub mov thiab dej haus xws li colas. Phosphoric Acid yog ib qho tseem ceeb muaj nyob rau hauv cov tshuaj tiv thaiv los tiv thaiv xeev siab. Phosphoric Acid yog tov nrog zinc hmoov thiab ua cov zinc phosphate, thiab nws yog ib qho tseem ceeb hauv kev kho hniav ib ntus. Hauv orthodontics, zinc yog siv los ua cov tshuaj etching los pab ntxuav thiab roughen ntawm cov hniav. Siv raws li cov tshuaj tiv thaiv chiv nyob rau hauv cov av nyob ib ncig ntawm ib tug granule acidification yog generated uas txhim kho cov kev siv ntawm phosphorus thov thiab muaj nyob rau hauv lub rhizosphere. Vim nws cov ntsiab lus nitrogen (tam sim no raws li ammonia), nws yog qhov zoo rau cov qoob loo uas xav tau cov as-ham hauv nws thawj theem.
