To choose a good adhesive, one must first understand the conventional knowledge of universal adhesive. Universal adhesive can be divided into two categories based on its composition: SBS and chloroprene rubber. chloroprene rubber has strong initial adhesion Good firmness Good durability SBS has many advantages such as strong environmental adaptability, but with a slightly stronger odor. Its characteristics are high solid content and low odor It has the advantages of environmental protection and low cost, but its adhesive strength and durability are not as good as chlorine nail glue. It is generally used indoors and in some situations with low requirements. It is also important to recognize the properties of the object being adhered to. Some difficult to adhere materials are not easily bonded with universal adhesives, such as polyethylene, polypropylene, polytetrafluoroethylene, and other organic silicon and snowflake iron materials. Plastic PVC, as well as plastic and leather materials containing a large amount of plasticizers, are also difficult to bond. In addition, it is necessary to consider the conditions and factors during use, such as temperature, humidity, chemical media, outdoor environment, etc. Taking into account these reasons and conditions, when considering what kind of universal adhesive to use, it is not necessary to choose the most expensive one, but it is necessary to choose the most suitable one.
Selection of universal adhesive
Versatile adhesive can bring great benefits no matter where it is used. Different groups have different needs, and with the continuous changes in the market, it is inevitable that inferior products will appear. Therefore, how to choose has become a problem. Today, let's take a look at how the manufacturer of versatile adhesive introduces it?
1. Go to supermarkets or distributors with a certain scale of building materials to make purchases.
2. Choose branded products from well-known universal glue manufacturers to ensure quality assurance.
3. Refuse to use products with rough packaging, deformation, and unclear labeling information.
4. Pay attention to the production date on the outside of the packaging, as expired products are likely to have a decrease in quality.
5. If the product is opened for inspection, pay attention to whether the gel of the universal glue is uniform, without layering or precipitation, and whether there is a pungent odor when opening the container.
In addition, it is necessary to understand the types of adhesives in order to better grasp the selection process.
1. Classified by chemical composition: It can be divided into organic adhesives and inorganic adhesives, while organic adhesives are further divided into adhesives and natural adhesives. Synthetic adhesives include resin type, rubber type, and composite type; Natural adhesives are divided into animal, plant, mineral, and natural rubber, etc; Inorganic adhesives have various chemical components such as phosphates, silicates, sulfates, and borates.
2. According to their morphology, they can be classified into liquid adhesives and solid adhesives.
3. According to their applications, they are divided into three categories: structural adhesives, non structural adhesives, and special adhesives.
4. According to the application method, it can be divided into room temperature curing type, thermosetting type, hot melt type, pressure-sensitive type, rewetting type, etc.
By understanding the relevant classification characteristics of adhesives, one can be more adept at making purchases.
Precautions for using universal adhesive during decoration:
Decorative universal glue can sometimes become cloudy, mainly due to the influence of humid weather. Universal glue can absorb moisture from the air, causing rust at the welding points of the glue barrel and even resulting in cloudy glue color. Therefore, decorative universal glue should be placed in a dry and ventilated place. Additionally, it should not be used in places where the temperature exceeds 60 ℃. If it must be used outdoors, the adhesive should be fully dried and cured, usually taking 72 hours; If construction is carried out directly outdoors, necessary measures should be taken to avoid light, and it can only be used after it is fully dried and cured.
When storing and transporting decorative adhesive, it should be kept away from sources of fire and heat, and direct sunlight exposure is strictly prohibited; Store and transport flammable materials, and pay attention to fire prevention for empty packaging drums after use
When opening the lid, hold the lid surface with your hand to prevent the glue from escaping. Immediately tighten the lid after use to prevent the universal glue from evaporating. If the adhesive has not deteriorated beyond its shelf life, it can still be used
It is advisable to let the decorative adhesive dry for 10-15 minutes after application, and the time should be postponed in winter.
