Mix the redispersible polymer natural powder with h2o within a percentage of 1:2, blend properly, allow it represent 2 minutes or so, after which mix yet again. Dump the solution over a clean, smooth glass work surface, position the cup within a cool and ventilated spot, and let it dry totally. Peel off the covering through the window and notice the polymer movie. The better the openness, the better the caliber of the polymer natural powder. Additionally, stretch the motion picture moderately the greater the suppleness, the higher the good quality. Cut the movie into strips and saturate it in h2o. After one day, see the standard of dissolution the less dissolution suggests the greater the standard.
Think about a suitable level of polymer natural powder, put it inside a aluminum pot, heat it to around 500 qualifications Celsius, incinerate it in a great temperatures of 500 degrees Celsius, and weigh up it once more following chilling. The lighter the load, the greater the high quality.
Examination the glue with cardboard or thin table. Consider two tiny items of cardboard or slender timber of identical dimension and use the sticky towards the interface of your samples to ensure even software. Put the two boards jointly, flatten them, and use tension with a bodyweight of 500g to 1000g for thirty minutes. Then, check the bond. If it is firmly set along with the interface is 100% damaged, this means that this sticky item is of high quality. If perhaps area of the user interface is broken, it means how the bonding strength is not really enough and also the quality is unqualified. In the event the program is intact, it implies the item is substandard or counterfeit.
