Background technology
The expansivity of weld car expansion damping sealing glue is an important performance indexes of this colloid.This index is too low and too highly all will cause adverse influence to corresponding weld car quality.Therefore, weld car expansion damping sealing glue for before weld car operation, all will be to the expansivity of the weld car expansion damping sealing glue used mensuration of sampling.
The mensuration of the expansivity of weld car expansion damping sealing glue all adopts drainage principle to carry out at present, and its basic skills is as follows:
1. at room temperature under state, first fetch a graduated cylinder, and inject therein a certain amount of distilled water, the volume of writing down distilled water is V
1(conventionally take the graduated cylinder of a 500ml, and in graduated cylinder, inject the distilled water of 350ml, write down the volume V of distilled water
1350ml);
2. the colloid of the expansivity to be determined of collection a certain amount of (for example 10 grams to 20 grams) is as test sample;
3. colloid test sample is immersed in the distilled water in aforementioned graduated cylinder completely, on distilled water waterline, moves, liquid volume corresponding to the note new waterline of distilled water is V
2;
4. test sample is taken out in the distilled water in graduated cylinder;
5. sample is placed in constant temperature oven and after temperature and time baking, is taken out in accordance with regulations, and be cooled to room temperature state;
6. cooled test sample is put back into measure in graduated cylinder and is immersed in distilled water and (as test sample swims on the water surface, with rectification folder, forces test sample to immerse in distilled water), on distilled water waterline, move, liquid volume corresponding to the note new waterline of distilled water is V
3;
7. utilize formula η=(V
3-V
2)/(V
2-V
1) * 100% calculates the expansivity η of test sample.
The problem existing is: during due to test, can only observe by range estimation mode the water level of distilled water, and estimate corresponding V with this
1, V
2and V
3numerical value; the gentle observation of working experience, observation water state of mind at that time of the accuracy of data and test job personnel etc. is all directly related; test experiments usually can, because the deviation between record data and True Data is compared with large failure, greatly affect work efficiency, experimental precision and the experimental cost of test experiments.
