Description
Technical field
The present invention relates to titanium dioxide technical field, especially a kind of detection method of titanium dioxide water absorption.
Background technique
The minimum amount of pure water needed for titanium dioxide water absorption refers to parent's profit 100g titanium dioxide completely.The water absorption of titanium dioxide
It is an important indicator of its performance quality, the water absorption of usually titanium dioxide is lower, and application performance is preferable, and for water suction
Amount detection, the detection of titanium dioxide water absorption do not have concerned countries standard, do not have systematic detection method yet.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of titanium dioxide water absorption detections for facilitating operation, accuracy rate high
Method.
The technical solution adopted by the present invention to solve the technical problems is: the detection method of titanium dioxide water absorption, including such as
Lower step:
A, the moisture in titanium dioxide to be measured is removed；
B, the titanium dioxide to be measured of moisture removal will be gone to be cooled to room temperature by step a；
C, titanium dioxide sample M1g is taken, and the titanium dioxide sample of acquirement is placed on operation panel；
D, pure water is added dropwise into titanium dioxide sample, until soaking titanium dioxide sample sufficiently；
E, it measures titanium dioxide sample in step d and sufficiently soaks the pure water amount M2g that terminal uses, and pass through formula M1/M2
× 100g is converted into titanium dioxide water absorption.
Further, titanium dioxide to be measured removes moisture removal in an oven, and the temperature of baking oven is less than 120 DEG C in step a.
Further, in stepb, titanium dioxide to be measured is cooled to room temperature in drying box.
Further, the value range of M1 is between 5-15g in step c.
Further, operation panel is ground glass plate or marble slab in step c.
Further, completing the time of step d between 15-20min.
The beneficial effects of the present invention are: first removing the moisture in titanium dioxide to be measured, make not containing moisture in titanium dioxide to be measured,
Titanium dioxide to be measured, is then cooled to room temperature, takes titanium dioxide sample after cooling by the accuracy for improving the detection of titanium dioxide water absorption
M1, then pure water is added dropwise into titanium dioxide sample, until soaking titanium dioxide sample sufficiently, it is abundant finally to measure titanium dioxide sample
The pure water amount M2g that wetting terminal uses, by obtaining titanium dioxide water absorption after conversion, the value of M1 is less than 100g, titanium dioxide sample
Time that product sufficiently soak and the pure water amount used are less, significantly improve the efficiency of detection；As it can be seen that titanium dioxide water absorption of the present invention
Detection method can be realized the detection of titanium dioxide water absorption, and facilitate operation, detection efficiency height, accuracy rate also high, conducive to pushing away
Extensively.
Specific embodiment
The detection method of titanium dioxide water absorption of the present invention, includes the following steps:
A, the moisture in titanium dioxide to be measured is removed；
B, the titanium dioxide to be measured of moisture removal will be gone to be cooled to room temperature by step a；
C, titanium dioxide sample M1g is taken, and the titanium dioxide sample of acquirement is placed on operation panel；
D, pure water is added dropwise into titanium dioxide sample, until soaking titanium dioxide sample sufficiently；
E, it measures titanium dioxide sample in step d and sufficiently soaks the pure water amount M2g that terminal uses, and pass through formula M1/M2
× 100g is converted into titanium dioxide water absorption.
In step a, removing the moisture in titanium dioxide to be measured is the standard in order to guarantee and improve the detection of titanium dioxide water absorption
True property, can be by removing moisture removal by the way of in an oven, and the temperature of baking oven is less than 120 DEG C.
In stepb, the titanium dioxide to be measured of moisture removal has been gone to absorb the moisture in air in order to prevent, by titanium dioxide to be measured
It is cooled to room temperature in drying box.
In step c, the value of M1 is less than 100g, can reduce the time that white powder sample sufficiently soaks and the pure water used
Amount, to improve the efficiency of detection.By obtaining in largely practicing and testing, the value range of M1 is between 5-15g, operation panel
It can be ground glass plate or marble slab.
In step d, when pure water being added dropwise into titanium dioxide sample, mixing is sufficiently squeezed with toolsetting, can be added dropwise every time early period
10 drops are even more, and 1 drop is added dropwise every time later can be swept by toolsetting when titanium dioxide sample is wetted at not rupturing, not dispersing
Reach the terminal sufficiently soaked when paste.In order to guarantee the accuracy of titanium dioxide water absorption detection, the time of step d is completed
Between 15-20min.
In order to further ensure the accuracy of titanium dioxide water absorption detection, every a batch titanium dioxide need at least carry out 5 sub-samplings,
It that is to say and at least repeat step c to step e5 times, the average value for acquiring each detection data is titanium dioxide water absorption.
In conclusion first removing the moisture in titanium dioxide to be measured, make to improve titanium dioxide without containing moisture in titanium dioxide to be measured
Titanium dioxide to be measured, is then cooled to room temperature, takes titanium dioxide sample M1 after cooling by the accuracy of water absorption detection, then toward titanium white
Pure water is added dropwise in powder sample, until soak titanium dioxide sample sufficiently, finally measuring titanium dioxide sample and sufficiently soaking terminal makes
Pure water amount M2g, by obtaining titanium dioxide water absorption after conversion, the value of M1 is less than 100g, and titanium dioxide sample sufficiently soaks
Time and the pure water amount that uses it is less, significantly improve the efficiency of detection；The quantity measuring method as it can be seen that titanium dioxide of the present invention absorbs water,
It can be realized the detection of titanium dioxide water absorption, and facilitate operation, detection efficiency height, accuracy rate also high, be conducive to promote.
