[China Glass Net] Although glass glue is very inconspicuous, it is an auxiliary material that is frequently used in the home decoration process. For example, it is used in the operation of the countertop and kitchen wall, the fixed basin and the toilet. . Some consumers often don't know the performance of glass glue, they often "come two bottles", no matter what material is glued, the same glass glue is used. In fact, different conditions apply to different properties of glass glue. And the quality of glass glue is also a consumer's special attention when buying.

Here are some tips for collecting concentrated glass glue:
First, recognize the brand:
In the end, the competition of products in the modern market is actually the competition of the brand. The glass glue products have already developed into the era of brand competition. Consumers should investigate and recognize a brand in all aspects: effective registered trademarks, distinctive image recognition, such as quality assurance, reasonable price positioning, perfect sales network, and thoughtful service system. Basis.
Second, look at the packaging:
Glass glue is generally packaged in PE plastic bottles, and some are packaged in aluminum or tin foil; then they are packed in cartons for handling. The pros and cons of glass glue products can be judged first and foremost from the packaging.
1. Look at the carton: The carton used by the responsible manufacturer has good texture and durability; the packaging design and printing quality are very beautiful; the product name, factory name, specification, origin, color, date of manufacture and other relevant information are accurate and detailed.
2, look at the plastic bottle: from the surface of the plastic bottle, the first easy to distinguish is the printing quality of the bottle: good product packaging and printing clear, detailed information, on the "use", "usage", "precautions" and other content Clear and complete, it reflects the responsible attitude towards users and consumers.
3. Specific net content: According to the relevant regulations of the state on product packaging, the manufacturer must indicate on the packaging the net content of the specification model (unit g or ml), but some glass glue manufacturers do not strictly implement the state. It is stipulated that only the gross weight or other code numbers are displayed on the bottle. Due to the large number, the illusion of “large amount of glue is added†is given. Some manufacturers have large net content on the bottle, but the thickness is actually thick. The thick-bottomed cover of the bottle is filled with glue. Generally, there is no obvious difference in the amount of the hand, which is deceptive to the user. Responsible manufacturers must truly indicate the net content of the product, and recommend thin bottles to the user. Even if some models use thick bottles, they will be explained to the user as thick bottles.
Third, the test gel:
If the user can only judge the quality of the manufacturer's work from the packaging, and can not judge the quality of the product, it is necessary to check the quality of the glue. There are several ways to judge the quality of glue conveniently and quickly:
1. Smell smell (applicable to acid glue): Acidic glue contains a kind of sour taste in the volatilization process because it contains acetic acid. However, the better the quality, the weaker the acidity of the gum, and the worse the quality, the stronger the acidity of the gum. (Because of the added acetic acid component); at the same time, the good quality of the glue disappears quickly during the curing process, and the poor quality of the acidity of the gum is much longer.
2, than the gloss: different quality of the glue after the out there is a difference in gloss, high-quality glue no matter what color is cured after the gloss is strong, low-quality glue has a dozen out of matt, some are cured after a month or two lost luster.
3, check particles: high-quality glass glue is a chemically synthesized material that is fully and evenly stirred, the texture is fine and uniform, smooth and smooth after sizing and curing. The worse the quality of the glass glue, the more particles and debris can be seen. After the sizing is cured, the surface of the strip is smoother and smoother than the good quality.
4, look at the bubble: the main component of high-quality glass glue is silicone, the amount of other added materials is very small, the good stability of pure silicone is minimally affected by changes in external conditions during storage, no bottle mixing occurs during sizing The air is used to make a "beep" or "beep" bubble. However, the ordinary quality silicone adhesive is not 100% silicone rubber. The additive in the silica gel and the PE soft rubber in the rubber bottle may cause a chemical reaction, which makes the rubber bottle swell and increase, and the air remaining in the space penetrates into the rubber. The slurry creates a void, and when the glue is applied, a "beep, slap" sound is emitted, which shortens the shelf life. What's more, a few manufacturers deliberately put the bottom cover on the bottom of the bottle when the glue is installed, and the air is left in the middle of the bottle, so that the amount of glue is greatly reduced, and it is inevitable that the glue is naturally produced.
5. Check the curing effect: After the partial sizing, the user should first check the dry time of the glass glue according to the instructions on the product packaging. If the time is too short or the timeout is too much, it indicates that the quality of the glass glue is problematic (of course, Consider the influence of environmental conditions); then wait for the curing to be completed (the curing time should also be noted by the manufacturer), try to test the hardness and elasticity of the rubber by hand, the rubber that is too hard or too soft is not good glue; then you can cut the glue The cross-section detection gel has the same curing effect inside and outside the glue.
6. Test tension and adhesion: The tensile strength and peel strength (ie, tack) of the silicone adhesive after curing are also different due to the difference in the quality of the silica gel. The high-quality rubber has strong tensile force, large stretching range and high peeling strength;
