Although the adhesive is only the supporting material in the building decoration, it does not mean that it is not important.A large number of materials in the actual decoration (such as wallpaper, all kinds of flooring, ceramic, stone decoration materials, etc.) are laid by pasting method, so the choice of appropriate adhesive directly affects the firmness of the laying, but also affects the decorative effect of the face.When choosing an adhesive, we should first understand its basic technical properties, which are the basic conditions to ensure the degree of bonding.

1.Processability refers to the performance of the adhesive related to the bonding operation, including the modulation, gluing, drying and curing conditions of the adhesive, and also the evaluation of the difficulty of the bonding operation.As mentioned above, multi-component adhesives should be deployed on the spot, chemical reaction adhesives have temperature conditions for curing reaction, solve-based adhesives need to be aired for a period of time after coating, until the solvent volatilization can be bonded and so on. These problems must be clear when choosing to use adhesives to ensure the bonding effect.

2.Bonding strength is to ensure the degree of bonding firmness performance indicators.The bonding strength is not enough, it will make the adhesive fall off, if the wall decoration, the adhesive will fall down, not only affect the quality of decoration, sometimes cause injury accidents.

3.Stability refers to the degree of strength change of the adhesive specimen after being immersed in the specified medium at a certain temperature for a period of time.Such as water resistance, oil resistance, etc. The measured strength is usually expressed or expressed by the strength retention rate. For the adhesive that wants to bond the ground, exterior wall or bathroom, toilet and so on the surface material, want to have very good stability.

4.Durability (or aging resistance) With the growth of the use of adhesive layer, its performance will gradually aging, until the loss of bonding strength, this performance is called durability.Because the largest amount of adhesive is now synthetic resin or synthetic rubber based on organic polymer materials, easy to aging in the process of use, so that the adhesive layer lost effectiveness and fall off.

5.Temperature resistance refers to the change in the performance of the adhesive in the specified temperature range. Including heat resistance (in high temperature environmental conditions), cold resistance (in low temperature environmental conditions) and resistance to high and low temperature change performance.These temperature changes will change the composition of the adhesive, so that the bond strength is reduced, until the adhesive layer falls off.

6.The weatherability is aimed at the adhesive parts exposed to the outdoors, which can withstand the weather, such as rain, sunshine, wind and snow and water wet performance, called weather resistance.The weatherability also reflects the aging resistance of the adhesive layer under the long-term effect of natural conditions. It is also because these natural factors will lead to the deterioration of the adhesive layer properties and affect the bond strength.

7.Chemical resistance,Most synthetic resin adhesives and some natural resin adhesives, under the action of chemical media will dissolve, expand, aging or corrosion and other different changes, resulting in the decline of bond strength.

8.Other properties In addition to the above introduced several properties (that is, various use of environmental conditions, such as temperature, humidity, sunlight, chemical media, etc., on the adhesive bonding layer bonding strength, comprehensively reflect the use of adhesive layer effect) must be considered in the selection of adhesives, other properties of adhesives should also be considered, such as: Whether there is a pungent odor, whether there is toxicity, how is the color of the adhesive, how is the storage stability, how long is the storage period and the price is high or low and so on.

For indoor use of the adhesive should be no pungent odor, no toxicity, if must choose an odor adhesive, then should be used after the adhesive layer is completely dry. According to the color of the sticky object, choose the similar color or white adhesive, so as to avoid the color of the adhesive pollution of the finish and affect the decorative effect of the finish. In addition, attention should be paid to the storage period of the adhesive, because after the storage period of the adhesive, the actual adhesive performance (especially the adhesive bond strength) will be greatly reduced, thus affecting the adhesive effect.
