如何測量液體氫氧化鉀的密度

發布來源:http://www.tmgwork.com    更新時間:2023-06-12 點擊數:

氫氧化鉀濃度比重計采用了防腐蝕液體密度測試配件,適用于測量具有流動性的腐蝕性及非腐蝕性液體密度、波美度、濃度的測量。常用于PCB電路板廢液、石油、汽油、柴油、尿素、氫氧化鉀、尿液、乙醇、蔗糖、香精香料、化妝品、卸妝液等液體的密度、波美度或者濃度檢測。
The potassium hydroxide concentration Hydrometer adopts anti-corrosion liquid density test accessories, which is suitable for measuring the density, Baume degree and concentration of corrosive and non corrosive liquid with fluidity. It is commonly used to detect the density, Baume degree or concentration of PCB circuit board waste liquid, petroleum, gasoline, diesel, urea, potassium hydroxide, urine, ethanol, sucrose, essence, perfume, cosmetics, makeup remover and other liquids.
氫氧化鉀密度計算公式
Calculation formula of potassium hydroxide density
氫氧化鉀濃度測定儀的測量原理為阿基米德浮力法,也稱作液體浸漬法。儀器自動通過已知密度ρ1的比重錘在空氣中的質量m1及其浸沒于待測液體中的浮重m2,將密度計算公式結合浮力計算公式后,演算出待測液體的密度計算公式:ρ=(m1-m2)ρ1/m1;而氫氧化鉀濃度檢測儀的內置軟件已經集成了密度、波美度及氫氧化鉀濃度的計算公式,能夠實現一次測量,即可獲得試樣的密度、波美度及濃度值的功能。
The measuring principle of the potassium hydroxide concentration meter is the Archimedes buoyancy method, also known as the liquid immersion method. The instrument automatically passes through a known density ρ The mass m1 of the specific gravity hammer in the air and its floating weight m2 immersed in the liquid to be measured are calculated by combining the density calculation formula with the buoyancy calculation formula to obtain the density calculation formula of the liquid to be measured: ρ= (m1 m2) ρ 1/m1; The built-in software of the potassium hydroxide concentration detector has integrated the calculation formula of density, Baume degree and potassium hydroxide concentration, which can achieve the function of obtaining the density, Baume degree and concentration value of the sample in a single measurement.
在測量過程中,無需人工計算,測試結束時儀器自動顯示樣品的密度值,按Mode可切換至樣品的波美度、濃度。而氫氧化鉀密度計測量液體波美度及濃度均是建立在液體密度測量的基礎之上。波美度分為輕波美及重波美,與密度均是呈線性關系的。
During the measurement process, there is no need for manual calculation. At the end of the test, the instrument automatically displays the density value of the sample. Press Mode to switch to the Baume degree and concentration of the sample. The measurement of Baume degree and concentration of liquid by potassium hydroxide densimeter is based on the measurement of liquid density. Baume degree is divided into light Baume and heavy Baume, and is linearly related to density.

線性關系可以簡單理解為y=ax+b,其中a,b值已知。電子密度計內置的程序會根據所得的密度比重值,自主選擇輕波美或者重波美的公式進行計算。而測量液體濃度,則需要先明確待測液體的密度及濃度能不能滿足線性關系,且要知道相應的計算公式。
The linear relationship can be simply understood as y=ax+b, where the values of a and b are known. The built-in program of the electronic densitometer will independently choose the formula of light or heavy wave based on the obtained density specific gravity value for calculation. To measure liquid concentration, it is necessary to first determine whether the density and concentration of the liquid to be measured can satisfy a linear relationship, and to know the corresponding calculation formula.
氫氧化鉀的濃度及密度的關系為y=100.1x-98.942,其中a=100.1,對應軟件中的E2;b=-98.942,對應軟件中的E1.
The relationship between the concentration and density of potassium hydroxide is y=100.1x-98.942, where a=100.1, corresponding to E2 in the software; B=-98.942, corresponding to E1 in the software
氫氧化鉀濃度計的使用方法
Usage of potassium hydroxide concentration meter
簡單安裝好支撐板及測量支架后,將不銹鋼掛鉤掛在測量支架上,歸零;在儀器0.000g狀態下,將鐵氟龍比重錘掛于掛鉤上,然后取一杯待測液體約50ml置于支撐板上,隨后移動盛放待測液體的杯子,將比重錘浸沒于待測液體內,待稱重數值穩定后,按Enter鍵,儀器自動計算并顯示樣品的密度值,按Mode鍵可切換氫氧化鉀溶液的波美度、濃度值。更多相關事項就來我們網站http://www.tmgwork.com咨詢!
After simply installing the support plate and measuring bracket, hang the stainless steel hook on the measuring bracket and reset it to zero; Under the condition of 0.000g of the instrument, hang the Teflon specific gravity hammer on the hook, take a cup of liquid to be measured about 50ml and place it on the support plate, then move the cup containing the liquid to be measured, immerse the specific gravity hammer in the liquid to be measured, after the weighing value is stable, press the Enter key, the instrument will automatically calculate and display the density value of the sample, and press the Mode key to switch the Baume degree and concentration value of potassium hydroxide solution.
