Wash the moldy glass glue with 84 disinfectant or toilet cleaner. The use method is to dip the discarded toothbrush in 84 disinfectant or toilet cleaner and brush the glass glue surface. This method is still effective for removing mildew spots on glass glue.
Glass glue is a kind of material that bonds and seals all kinds of glass with other substrates. Mainly divided into two categories: silicone adhesive and polyurethane adhesive (PU). Silicone sealants is what we usually call glass sealant, which can be divided into acidic and neutral. Neutral glue is divided into: stone sealant, mildew sealant, fire sealant, pipeline sealant, etc.
Glass glue can be divided into neutral glass glue and acidic glass glue according to its performance. Generally used for home improvement bonding. The places where glass glue is generally used for home decoration are: the dumb mouth on the back of wooden line, sanitary ware, bathroom, toilet cosmetic mirror, gap between sink and wall, etc. Glass glue with different properties should be used in these places.
Neutral glass adhesive relay is relatively weak and is generally used on the back of bathroom mirror without strong adhesive force. Neutral glass glue is widely used in home decoration, mainly because it will not corrode objects, while acidic glass glue is generally used in the dumb mouth on the back of wood grain, with strong adhesion.
Common types of glass glue:
1, single and two-component classification.
Silicone glass glue can be divided into two categories from product packaging: one-component and two-component one-component silicone glue, whose curing depends on the change of physical properties caused by contact with moisture in the air; Two-component refers to that silicone adhesives are divided into two groups, A and B. When they exist alone, neither group can cure, but once the two groups of adhesives are mixed, they will cure. One-component silicone glass glue is common in the market.
2. Classification of pH value.
Silica gel glass glue can be divided into acidic glue and neutral glue according to its acidity and alkalinity. Acid glass adhesive is mainly used for general bonding of glass and other building materials. Neutral glue overcomes the characteristics of acid glue corroding metal materials and reacting with alkaline materials, so it has a wider application range and its market price is slightly higher than that of acid glue.
A special kind of neutral glass glue on the market is silicone structural sealant. Because the metal directly used for glass curtain wall is bonded with glass structure or non-structure, its quality requirements and product grade are the highest among glass adhesives, and its market price is also the highest.
3. Color classification.
Silica gel glass glue has many colors, and the commonly used colors are black, china white, transparent, silver gray, gray and bronze. Other colors can be customized according to customer requirements.
