Technical Field
The invention belongs to the technical field of detection of PH of glue solution in a Seell production system, and relates to a method for detecting the PH value of the glue solution.
Background
The lyocell fiber is one of regenerated cellulose fibers, which is made from wood pulp of plant origin through a solvent spinning method to form cellulose fiber, and then the cellulose fiber is woven into textile to enter the consumer market, and the product can be completely decomposed in soil. The glue solution is used as an intermediate product of the lyocell fiber and is very important for detecting the characteristics of the lyocell fiber, and the quality of the produced fiber is directly influenced.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a method for detecting the pH value of glue solution. The PH is used to measure the activity of hydrogen ions in a substance. The activity is directly related to the acidity, neutrality and alkalinity of the aqueous solution. Is alkaline at pH 7, neutral at pH 7 and acidic at pH < 7. The pH value is also related to the quality of the glue solution produced.
A method for detecting the pH value of glue solution comprises the following steps: the pH value was measured by a pH meter, and the temperature was constant.
The most common direct measurement method of the PH meter is adopted in the invention. The laboratory instrument and sample are prepared. Firstly, adjusting a constant-temperature water bath to a specific temperature (60 ℃), putting in a sealed glue solution, measuring the actual temperature by using a thermometer, measuring by using a calibrated PH meter and an electrode after the temperature to be measured reaches 60 ℃, reading after the PH value is stable, and determining the PH value after repeating the measurement for several times.
The invention has the advantages that the technical problem to be solved is that the field of lyocell is not completely developed at present, a simple and effective method is lacked for detecting various items of lyocell, and the method can be used for detecting the PH value in the glue solution more conveniently and conveniently for manufacturers related to lyocell glue solution in the production process. The pH value of the glue solution in the production process is generally alkaline.
The method effectively measures the pH value in the glue solution, fills the blank of the detection method in the field, is simple and convenient, and can be widely applied to the industry.
