Glass glue is actually useful to every household, but many people do not understand, let the construction master use their own cheap glue, the result after their stay in the adhesive place there is cracking, yellow, mildew and other problems, such as the sink, the toilet will leak, affecting their good mood to stay.
1.Waht's glass glue?
First of all, let's understand, what is glass glue? When it comes to glass glue, it is recognized that it is a professional "closing tool", indeed, glass glue is a commonly used home decoration adhesive, composed of sodium silicate and acetic acid and organic silicone, which is called "silicone sealant".
Mainly divided into silicone glue and polyurethane glue (PU) two categories, according to its performance can be divided into neutral glass glue and acid glass glue, of which acid glass glue is mainly used for general bonding between glass and other building materials, and neutral range of application is wider, wardrobe, basin, toilet can be.
Acid glass glue will have a very pungent acidic taste after opening, but its adhesion is strong, sealing is good, and the solidification speed is fast, and the taste will dissipate after solidification. Acid glass glue is corrosive, so be sure to pay attention to safety when using. Generally used in the wooden line behind the dumb mouth, kicking line and other places that need particularly strong adhesion. Neutral glass glue solves the corrosion and pungent problems of acid glass glue, and is used more widely.
The solidification rate of neutral glass glue is slower, usually in about four hours to solidify, metal, glass, marble, etc., can be used. However, the price of neutral glass glue in the same brand is generally higher than that of acidic glass glue.
2.How to choose glass glue with good mildew resistance?
How to choose the mildew resistance of glass glue? For the bathroom, kitchen such as a relatively damp place, the purchase of glass glue, as far as possible to choose with mildew, moisture resistance of the glass glue.
Mildew proof silicone sealant is the future trend, with mildew proof effect of silicone glue than the general glue to use longer, more firm, not easy to fall off, especially suitable for some wet, easy to grow mold environment, such as bathroom, kitchen and so on. In the national standard, the anti-mildew effect is divided into 0-4 levels, 0 level is the best, 4 level is the worst. The conventional mold culture cycle is 28 days, that is, there is no obvious mildew under 50 times amplification in 28 days, which indicates that the anti-mildew effect of glass glue is good.
The tensile strength and peeling strength of glass glue after curing will be different due to the difference in the quality of its silica gel. Generally, the tensile strength of high-quality glue is very strong, the tensile range is large, and the peeling strength is high. Such glue is not easy to crack with use, and it is not easy to fall off.
3.What is the main anti-mildew effect of silicone anti-mildew glue?
1) After the addition of anti-mildew agent, the outer membrane of mold spores contact the anti-mildew agent and adsorb, and then the anti-mildew agent enters the protoplasm and acts on the inside of microbial cells, destroying the original structural system inside the cell and inhibiting or changing the environment for mold growth and reproduction;
2) After the addition of anti-mildew agents, the anti-mildew agents interact with life molecules such as mold proteins, resulting in microbial individuals unable to maintain normal physiological activities and death, so as to achieve the purpose of killing mold individuals and reducing mold numbers.
Mildew prevention, also known as mildew resistance and mildew resistance, refers to the ability to tolerate, prevent or inhibit the growth and reproduction of mold spores and mycelia on colloidal surfaces. Therefore, the use of silicone anti-mold sealant does not mean permanent anti-mold, but inhibits the number of mold breeding, delaying the growth rate of mold, so silicone anti-mold sealant has a certain anti-mold years, should be replaced after mold, choose the highest anti-mold grade (0) silicone sealant, the use of better effect.
