Adhesives called "cold welding" are well known and used both in Russia and around the world. One of the representatives of this type of composition is cold welding "Almaz". Due to positive reviews about its quality, the glue has gained popularity and is often used in construction and finishing work.
Properties
Almaz glue is unique in its properties, its use does not create any special problems. A pleasant bonus is the adequate price of the product. The range of applications is quite extensive - the tool can be used for a wide variety of work: from repairing a water supply system to gluing car parts.
The glue is packed in plastic cylinders and wrapped in cellophane. It is white in color, but inside it has a gray core, which does not initially mix with the base.
The white base is quite sticky and can partially remain on the hands when working . This has a bad effect on the basic properties of the composition. To remedy the situation, you need to wet your hands in cold water before using the glue.
Cold welding of this brand is packaged in cylinders of various sizes, which is convenient for consumers. It is necessary to prepare for use only the required amount of material, since its surplus will solidify after a while and it will be impossible to apply them. Therefore, it is recommended to use not the whole mixture at the same time, but in parts.
Before you mix the glue, you need to make sure it is soft. It is also convenient to cut it. However, after the material is mixed, it becomes solid.
Compound
Cold welding "Almaz" consists of a hardener and epoxy resin. To them are added fillers of two types - mineral and metal.
The main advantages of the material:
- due to its versatility, this adhesive can be used in a wide range of applications;
- this type of cold welding does not create problems in use, the application does not require specific skills and abilities;
- work does not require any specific tools, you can cope with the help of available tools;
- packing in packages of different sizes makes the purchase of welding convenient for the consumer;
- is in a low price category;
- welding is easy to store, it is quite unpretentious and does not require specific conditions.
The main disadvantages of the material:
- when the composition dries or has already dried, it is quite easy to break it due to its fragility;
- it is used mostly in everyday life, since it does not withstand serious loads and mechanical stress;
- if lumps appear inside the composition during the application process, this has a bad effect on the quality of the product;
- the material can stick to a dry surface;
- relatively short service life, especially under adverse influences.
Where is applied
In cases where objects cannot be glued using other compounds, it is recommended to use cold welding "Almaz". In the event that a broken ceramic item is badly damaged or a small part is lost, glue can be used to restore it. A figure is sculpted from it, or the resulting hole is filled with material, and after solidification, the area becomes dense, and the parts are securely fastened.
This mixture can stick together not only homogeneous materials, but also different in texture . To do this, it is necessary to thoroughly clean the surfaces from dirt and dust and then degrease them.
The only caveat is that the restored items will not withstand severe stress and strong mechanical stress. Cold welding "Universal Diamond" with a volume of 58 g is used at normal temperatures, it is recommended to exclude their strong drops.
Views
Cold welding " Diamond " may vary in volume and composition. In terms of composition, it is divided into several types.
Universal adhesive " Union " can be used in works of different directions. The type of surface does not matter, it is used with both homogeneous and dissimilar materials.
When repairing furniture and working with wood, cold welding is used for woodworking. It helps to eliminate delamination, and also adheres well to the coatings themselves.
A special subtype of glue is also used in car repairs . With it, you can glue small parts, get rid of chips on the machine body. Also used for thread restoration.
When working with metal objects, it is recommended to use cold welding "Almaz", in which there is a steel filler. Can join nonferrous and other types of metal.
Plumbing adhesive - moisture and heat resistant . When using it, tightness is achieved. It is used when working with pipes and other plumbing connections.
Highlights at work
The maximum working temperature when using cold welding "Almaz" is +145 degrees. The composition hardens in a period of about 20 minutes, but it takes about a day to completely solidify. It is recommended to apply glue at +5 degrees.
Before using the composition, it is necessary to prepare the surface . It must be cleaned of dust and dirt and then degreased.
The composition itself must be used in the correct proportions. The volume of the outer part should be equal to the volume of the core. The glue is mixed until a soft homogeneous consistency, after which you can work with it.
If the surfaces treated with the composition are wet, when applying the glue, it must be smoothed for better adhesion to the material. After that, a tourniquet should be applied for 20 minutes. If you need to speed up the drying process, you can use a regular hair dryer. When heated, the composition hardens much faster.
The room in which the work is carried out must be properly ventilated. The use of gloves will not be superfluous.
Instructions for use
The use of the composition should be carried out according to the instructions, in compliance with all requirements, then the work performed will delight a long period of time. Summing up, there are several stages of work with cold welding "Almaz".
It is necessary to start the process with surface preparation . It is cleaned of dust and other contaminants and thoroughly degreased.
After that, the glue is mixed. It is necessary to pay special attention to the equal volume of the outer and inner parts of the train. Since the glue dries quickly enough, it is best to use a small amount of the product for the job.
The glue is thoroughly mixed and kneaded . It should become soft and resemble plasticine in consistency. After that, the necessary figures are fashioned from it, or the composition is applied to one of the surfaces to be glued.
Complete drying of cold welding "Almaz" is about a day. After that, the processed item is completely ready for use.
