Can silica be judged when it is in the shape of a liquid? Can it be judged when it is in a specific shape? The first trick to judge the quality of silicone: hope You can see the color of the silica gel. The uncolored silica gel is pure white or translucent. If the silica gel contains impurities, the silica gel may turn black or yellow, etc. Judging the quality of silicone Some people will be surprised. This chemical product can tell whether it is good or bad? In fact, liquid silicone is roughly divided into condensation type and addition molding silicone. Generally, these two types of silicone have no taste, but condensation silicone His curing agent will have a little taste. The third trick to judge the quality of silicone: burn Does it seem violent? This method can tell whether this material is silicone. After curing, the silica gel will show a white flame, and the ashes after burning will be white powder. And silicone has a certain flame retardancy, and then he will calm down naturally after a certain time. The fourth trick to judge the quality of silicone: touch The main purpose of this method is to feel the dryness of the silica gel. Some silica gels have a sticky surface after curing, maybe oily, sticky may be the silicone is not completely cured, or the hardness is too low. Description of oily oil Silicone oil is more fierce, and some will affect the production quality of the product. The fifth trick to judge the quality of silicone: pull Pulling can judge the function of the silica gel. This is also better understood. Some silicones break as soon as they are pulled, or they may crack as soon as they are torn. This function is directly related to the economic function of silicone. Judging the quality of silicone To bake is to put the cured silica gel into the oven and bake it, and adjust the temperature to a certain temperature. Generally, the temperature resistance of silica gel is 150 degrees, and the temperature resistance is 300 degrees. I can learn the above six methods to judge the quality of the silicone, and next time I can judge the quality and grade of the silicone. Even if it is a liquid shape, it is still a mold shape, it is still a product shape, and it can be used.
