HOW TO CHOOSE FILTER BAG MATERIAL ACCORDING TO PH VALUE

PH Value Definition:

The hydrogen ion concentration index (PH) refers to the ratio of the total number of hydrogen ions in the solution to the total amount of substances. A value indicating the degree of acidity or alkalinity of a solution, that is, the negative value of the common logarithm of the concentration of hydrogen ions contained. pH=﹣1g[H ]

 

Acid Judgment:

At 25°C

Neutral solution, pH=7

Acidic aqueous solution, c (H ) >c (OH ), pH<7, the smaller the pH value, the stronger the acidity;

Alkaline aqueous solution, c (H ) <c (OH ), pH>7, the greater the pH value, the stronger the alkalinity.

In neutral solution at 100°C, pH=6

 

PH VALUE AND CONCENTRATION

Definition of concentrated acid:

Concentrated sulfuric acid, the mass fraction exceeds 70%, and the substance concentration is 18mol/L.

Concentrated hydrochloric acid, the mass fraction exceeds 37%, and the substance concentration is 12mol/L.

Nitric acid, the mass fraction exceeds 65%, the substance concentration is 8mol/L

 

PH represents acidity and alkalinity:

The acidity and alkalinity that can be expressed by PH, the concentration should be less than 1mol/L, when the concentration is 1mol/L, if it is acidic, the PH value is 0, if it is alkaline, the PH value is 14.

Concentrated sulfuric acid, concentrated nitric acid, and concentrated hydrochloric acid can not use the PH value to indicate that the mass fraction of dilute sulfuric acid is less than 4.5% can be used to indicate the PH value. When the mass fraction is 4.5%, the concentration is 1mol/L and the PH value is 0.

Dilute hydrochloric acid with a mass fraction of less than 9% can be expressed by PH value. When the mass fraction is 9%, the concentration is 1mol/L and the PH value is 0.

Dilute nitric acid with a mass fraction of less than 9% can be expressed by PH value. When the mass fraction is 9%, the concentration is 1mo1/L, and the PH PHI value is 0.

Applicable Range of PH Value

材质	使用PH值范围
Material	Applicable range of PH value
PP	1-13
PE	5-8
PET	PET fiber is stable to weak acid and weak base, and will decompose under the action of strong acid, strong base and water vapor
PTFE	1-14
Stainless Steel	1-14
Nylon	Different concentrations of organic acid, alkali or salt can cause the swelling, dissolution or hydrolysis of PA
