Do not know what you think about glass glue and structural glue, in daily life, as a kind of home decoration commonly used adhesive, these two are very widely used, constitute the first product of home decoration building, so for the common problems of glass glue or structural glue how much do you know? How was it solved? Auman environmental protection glass glue manufacturers for you to introduce!

        1. Why does neutral porcelain white glue turn pink? Some gels cure a week and then return to porcelain white?

        A: Alcohol type of neutral glue may have this phenomenon, it is caused by the production of raw materials titanium chromium compound. The titanium chromium compound itself is red, and the porcelain white color of the glue is the titanium dioxide in the glue. But glue is organic matter, and the vast majority of organic chemical reactions are reversible reactions, and there are side reactions. Temperature happens to be the key to causing these reactions. When the temperature is high, the positive reaction will change the color, but when the temperature is stable, the reaction will reverse and return to the original shape. Production technology and management of good, should be able to avoid this phenomenon.

        2, some domestic glass glue in the sizing bubble sound, what is the reason?

        A: There could be three reasons:

        First, when the technology is not passed, the glue bottle is mixed with air;

        Two, a few unscrupulous manufacturers deliberately do not press the bottom of the bottle, the bottle has air but gives people the feeling that the amount of glue is sufficient;

        Three, some domestic glue because it is not silicone glue, the increased filling material will have a slight chemical reaction with the PE soft glue of the glass glue packaging bottle, so that the plastic bottle has the phenomenon of swelling and increasing, the air retained in the space into the glue to create a gap, when sizing will play bubble sound. The effective way to overcome this phenomenon is: change to hard bottle packaging, pay attention to the product storage environment (under 30℃ cool).

        3, why in summer some neutral glue in the combination of concrete and metal window frames after curing will appear a lot of bubbles, and some will not? Is it a quality problem? Why hasn't this happened before?

        A: Many brands of neutral glue have had a similar phenomenon, after careful testing and repeated experiments to confirm that the quality of the glue is not the problem. Because there are two kinds of neutral glue, alcohol type and ketone oxime type, and alcohol type glue in the curing process of methanol will release gas (methanol starts to volatilize at 50℃), especially when the sun or high temperature reaction is more intense. In addition, concrete and metal window frames are difficult to breathe, and the summer temperature and humidity are high, the curing will be faster, the gas released by the glue can only run out of the never completely cured rubber layer, and the bubbles of different sizes will appear on the cured rubber strip. And ketone oxime type neutral glue in the curing process will not release gas, will not produce bubbles.

        But the disadvantage of ketone oxime type neutral glue is that once the technology and physical treatment is not good, there is a chance of shrinkage and cracking phenomenon when it is cold in the curing process in winter, and the technology is good, there is no such phenomenon. Of course, the neutral glue of ketone oxime type is slightly more expensive than alcohol type. In the past did not appear similar phenomenon because in the past construction units in this place with little silicone glue, generally often use acrylic waterproof sealing materials, so the phenomenon of silicone neutral foaming is not very common; In recent years, silicone sealant has been widely used, which greatly improves the grade of engineering quality, but due to the characteristics of the material is not

Understand that improper material selection causes sealant foaming phenomenon.

        The following points should be noted to solve such problems:

        It is prudent to do a local use test first to observe whether it meets the needs of use (generally two or three days after sizing can see the reaction);

        Two, distinguish the use of time and base material type, choose the appropriate neutral adhesive use: summer choose ketone oxime type, winter choose alcohol type;

        3. Keep the construction surface clean and dry;

        Four, summer sizing should avoid high temperature period (above 35℃) and direct sunlight, generally in the evening is more appropriate;

        5. Similar projects will be tracked by technical personnel of the manufacturer.

        4, neutral glue dry glue, the surface of the powder like things, what is the reason?

        A: There are several cases in general:

        (1) The phenomenon of pulverization of rubber strip is that the selection of raw materials of rubber itself has defects;

        (2) Uneven mixing of raw materials;

        (three), may be due to the impact of the construction environment, more dust is easy to adsorption on the rubber surface and this situation.

        5, bathroom or kitchen common glass glue yellow, mildew, black is what reason?

        A: Bathroom, kitchen and other places are often damp and dark, and the glass glue will become yellow and black due to mold. Therefore, the bonding, sealing and caulking of visible objects in the bathroom, including the bathtub, bathtub, bath mirror and pipes, should be paid attention to.

        6, why neutral adhesive bonding some aluminum plastic board, plastic steel doors and Windows effect is not good or stick?

        Answer: This phenomenon generally appears in alcohol-type neutral adhesive, because the miscibility of the material on the aluminum plastic plate and the plastic steel door and window is not good, which affects the bonding quality. In this case, it is recommended that users choose ketone oxime type neutral glue, which will greatly reduce the occurrence of this situation; If the user chooses alcohol type neutral glue, should first use acetone or xylene wipe

        Substrate surface, to be completely dry after the substrate surface sizing; The scrubbed substrate should be constructed within one hour. Therefore, we repeatedly emphasize that because of the diversity of substrate materials, users should test the compatibility between glass glue and substrate according to their own needs before use, in order to observe whether it meets the use needs.
