The difference between structural adhesive and tile adhesive What is the difference between structural adhesive and glass adhesive

Structural adhesive (compression strength> 65MPa, steel-steel tensile bonding strength> 30MPa, shear strength> 18MPa) has higher strength than ceramic tile adhesive, can withstand large loads, and is resistant to aging, fatigue and corrosion. It has stable performance in the expected life and is mainly used for pasting decorative materials such as ceramic tiles, face tiles and floor tiles. Ceramic tile glue, also known as ceramic tile adhesive or binder and viscose clay, is a new material for modern decoration, replacing traditional cement yellow sand, and is suitable for pasting ceramic tiles on gypsum board, fiberboard, plywood or old finishes (ceramic tiles, mosaics, terrazzo), etc. and for pasting various stone plates of larger sizes. The bonding force of structural adhesive is several times that of cement mortar, which can effectively paste large ceramic tile stone and avoid the risk of brick falling. Good flexibility to prevent the production of empty drum. Widely used in interior and exterior wall surface, floor, bathroom, kitchen and other building decorative decorative places. Its main characteristics are high bonding strength, water resistance, freeze-thaw resistance, good aging resistance and convenient construction. It is a very ideal bonding material. Tile glue is a kind of polymer modified cement-based tile glue, which is divided into No. 1 (ordinary type), No. 2 (enhanced type) and No. 3 (larger size tile or marble) and other varieties. The bonding force is large, more flexible, and can resist the stress generated by the thermal expansion and contraction of the bonding layer. In addition to gray, tile glue can also be provided with a white appearance, suitable for light or translucent marble, ceramic tiles and other natural stone.

Common Problems and Solutions of Curtain Wall Glue Construction

Curtain wall glue is an indispensable material in construction engineering. The curtain wall structure of the whole building needs to use it, which can be described as "invisible hero". Curtain wall glue high strength, anti-stripping, impact resistance, simple construction process, widely used in construction and installation, decoration, sealing, structural adhesive and other fields. The development direction of modern architecture will be design standard (standard, construction mechanization, prefabrication of components (light weight, high strength and multi-function of building materials. The wide application of curtain wall engineering glue will speed up the process of the four modernizations, and it is of great significance in improving the construction speed, beautifying the building, improving the construction quality, saving working hours and energy, reducing pollution and so on. Therefore, curtain wall glue has become one of the important chemical building materials. What common problems will be encountered in the construction of curtain wall engineering glue that plays a key role? How do we deal with it?

How long does the glass glue dry and the curing time of the glass glue

What determines the curing time of glass glue? To solve this problem, we must first understand the principle of glass glue curing. The principle of glass glue bonding and curing is a chemical reaction, absorbing water molecules in the air to produce a cross-linking reaction to generate a rubber body with a network structure. The speed of glass glue hardening is related to the contact surface with the air. The larger the contact surface block, the faster the hardening. At the same time, you can look at the storage environment of glass glue. Glass glue should be stored in a cool and dry place below 30 ℃. It can be concluded that the sealed glass glue is mainly cured or related to the surrounding temperature and moisture, and these two factors determine how long the glass glue is dry. According to the regular curing time, acid glue and neutral transparent glue should generally be within 5-10 minutes, neutral variegated glue should generally be within 30 minutes, and the curing time of glass glue increases with the increase of bonding thickness. For example, acidic glass glue with a thickness of 12mm may take 3-4 days to solidify, but within about 24 hours, the outer layer of 3mm has been cured. The curing time of glass glue is relatively short, especially the glass glue that has been opened needs to be used in time. The storage environment should be paid attention to. Temperature and air humidity, generally acidic glass glue can be stored for more than 6 months, and neutral weather-resistant and structural glue can guarantee the shelf life of more than 9 months.

Durable Stability of Silicone Structural Adhesive and Quality Control Measures of Glass Curtain Wall

Glass curtain wall is widely used because of its beautiful appearance, energy saving, easy maintenance and many other advantages. The glass curtain wall is a structural exterior wall assembled on the basis of a single element of the glass curtain wall sealed by adhesive bonding. The glass unit is elastically connected with the metal frame by silicone structural sealant. The structural sealant plays a structural bonding role and transmits and bears the stress of the main structure. Therefore, the durability and stability of silicone structural sealant are directly related to the safety of the curtain wall. Once the structural adhesive bonding failure, it will lead to the failure of the entire curtain wall system, and even produce breathable water leakage, glass falling off and other accidents, resulting in extremely adverse social impact. With the increasing of glass curtain wall engineering, the quality problems of glass curtain wall engineering caused by structural adhesive are becoming more and more prominent. This paper analyzes the typical quality problems of glass curtain wall from the perspective of silicone structural sealant, and puts forward the corresponding quality control measures of glass curtain wall by expounding the product quality control project requirements set by the new standard of construction industry "silicone structural sealant products for building curtain wall" (hereinafter referred to as "new standard").

Analysis of Common Problems in the Use of Structural Adhesive

Structural adhesive is high strength, can withstand large loads, and aging resistance, fatigue resistance, corrosion resistance, stable performance in the expected life, suitable for structural bonding adhesive. It is mainly used for bonding between metal, ceramic, plastic, rubber, wood and other materials or different materials, and can partially replace traditional connection forms such as welding, riveting, bolt connection, etc. Silicone structural sealant is the key material used in the full or semi-hidden frame glass curtain wall. By connecting the plate and the metal frame, it can bear the wind load and the self-weight load of the glass, which is directly related to the durability and safety of the building curtain wall structure, and is one of the key links of the safety of the glass curtain wall. It is a structural sealant with linear polysiloxane as the main raw material. In the curing process, the crosslinking agent reacts with the base polymer to form an elastic material with a three-dimensional network structure.

Performance and Service Life Analysis of Structural Adhesive

The performance and life of silicone structural adhesive is a topic of long-term concern in the industry, manufacturers, construction units, direct users and designers are very concerned. The small rubber strip is like a sewing thread, which connects the building firmware elastically and bears the corresponding force. Like sewing thread, the amount and cost of this material is not large, but the role is very critical. Since most of the main materials of the building are inorganic, the durability of these main materials is generally guaranteed. However, silicone structural adhesive is an organic material, and its durability is not as good as that of inorganic materials. Therefore, silicone structural adhesive should be a controlled and restricted material that affects the service life and structural safety of curtain wall buildings.
