Glass glue, is a family commonly used adhesive, the main ingredient is sodium silicate (Na2O·mSiO2), soluble in water, viscous, also known as sodium silicate in the south, also known as paolin in the north.
Acid silicone glass adhesive: a wide range of bonding, most of the building materials such as glass, aluminum, non-oil wood has excellent bonding. But can not be used for bonding ceramic, marble, etc.
Neutral silicone glass glue: can be used for bonding ceramic sanitary ware, marble, etc.
Acid glass adhesive strong bonding force, some materials have a certain corrosive, suitable for limited materials, stimulating taste is also large; Neutral glass glue is suitable for marble, metal, glass and other materials, less irritating taste, but the bonding force is weak; Waterborne glass glue, weak bonding force, slow curing process, but after drying can be painted on it, in the process of home decoration used less.
Because many people do not understand the performance of glass glue, it is easy to reverse the neutral glass glue and acid glass glue, resulting in unnecessary trouble, such as the installation of mirrors if the acid glass glue will lead to the mercury on the back of the corrosion.
The fish tank has high requirements for the waterproof and bonding performance of the glass glue. The acid structural sealant should be used, and the new glass glue of polyurethane can also be used. But its price is relatively high, about 100 yuan for a bottle of 300 ml glass glue.
When using glass glue, there are also some matters to pay attention to, otherwise it will affect the service life of glass glue. The life of ordinary glass glue is about 5 years, even the life of high-grade glass glue is only seven or eight years, so when it comes to a certain number of years, you should pay attention to whether the glass glue in your home should be replaced; Glue should find a professional operation, to avoid their playing uneven, uneven; When the adhesive surface should be no oil, no pollution, no water; Do not use the glued appliance within 24 hours after gluing. The shelf life of glass glue is more than one year to one and a half years, the shelf life of glass glue will be unable to be used because of curing, the shelf life of glass glue will be shortened correspondingly after opening, and the degree of curing of glass glue should be carefully checked before using.
Acid glass glue in the curing process will release irritant gas, the eyes and respiratory tract has an irritating effect. Alcohol-based neutral adhesive releases methanol during curing. Methanol is a potential carcinogen and is a known skin and respiratory allergen, and the volatile gas can irritate the eyes, nose and throat. Therefore, this product should be used in a well-ventilated environment, avoid entering the eyes or long-term contact with the skin (after use, before eating, smoking should wash hands), do not swallow this product. Keep out of reach of children; The construction site should be well ventilated; In case of splash into eyes, rinse with water and seek medical attention immediately. Fully cured glass glue has no risk.
