Joiner glue is designed to connect parts from paper, cardboard, wooden boards, bars, hardboard. The material is inexpensive, safe, has a natural composition.
Composition
The basis of wood glue, the main agent is animal protein.
By type of feedstock there is glue:
- hair
- fish
- bone,
- casein
- polyvinyl acetate (PVA),
- moisture resistant.
For carpentry, all types are used.
Mezdrovy
The main active ingredient is obtained by processing the skin of animals. Protein is the subcutaneous layer without adipose tissue. Its composition includes oligopeptides. They contain cysteine, which forms bridges for the reliable connection of parts.
Coated wood glue is produced in the form of:
- powder
- tiles
- flakes.
Isinglass
For the production of fish glue use fins, scales, swimming bubbles. It turns out a solution suitable for gluing identical and dissimilar surfaces. The only drawback is the high price. They release glue in the form of dry scales and granules.
Bone
Make from the bone residue of animals. The composition includes:
- collagen,
- gelatin,
- cysteine.
These substances are viscous, reliably glue the surface of wooden products. The price of the material is low. Transparent compositions should be chosen: they are better than untreated, cloudy, with impurities.
Casein
Includes:
- casein,
- kerosene,
- blue vitriol
- sodium fluoride,
- slaked lime.
Disadvantages:
- Significant shrinkage in volume.
- Change the color of glued surfaces.
- The short shelf life of the prepared solution is several hours.
It holds the wood parts together well.
Raw materials for the preparation of casein adhesive solution are available in the form of a dry powder.
PVA
PVA glue is used in carpentry and other areas. The solution is sold ready-made.
Specifications:
- elasticity,
- reliable grip
- transparent layer
- stability of the finished seam.
PVA adhesives vary in quality. Some are waterproof, quick-drying.
Moisture resistant
A waterproof solution for gluing wood can be prepared from slaked lime and freshly curd. The components are mixed in certain proportions to a working consistency.
How to make a mixture
To prepare the working material, ready-made grain, dry powders, tiles, granules are taken. They are thoroughly crushed, diluted with warm water according to the instructions. Waiting for swelling of the active components. Then use. Store in a sealed container. All formulations, except casein, retain adhesive properties for several days.
The method of preparation is prescribed in the instructions on the package. Different manufacturers may have different mixes. Consistency matters. In the description of a particular adhesive, the required amount of water is indicated. It is designed to produce a mixture of a certain viscosity. If more liquid material is needed for work, the liquid is added in small portions, each time the paste is thoroughly mixed.
Before gluing surfaces to each other, they are cleaned and degreased. Then a thin layer of solution is applied to one of the parts, the planes are pressed. To increase the effect, a load is placed on top, it prevents the workpieces from dispersing. Bonding occurs in 2-3 hours, drying - in 2-3 days. The exact terms and conditions are spelled out in the technical specifications of each train.
Modern adhesives on a synthetic basis
Often used ready-made adhesives for industrial production: Titebond, Moment, Titanium.
Titebond (from 200 p., 0.296 liters.)
Glue for wood Titebond of the American company Franklin International is used in the manufacture of furniture from plywood, floor coverings from wood, in finishing works with wooden products. The composition includes synthetic and natural polymers without solvents. This allows you to get excellent adhesion of surfaces without damaging them.
Titebond II Premium wood glue is a high-quality replacement for traditional wood and paper gluing compounds. It is used in the manufacture of door and window blocks, frames, furniture assembly. This is a composition with a high level of moisture resistance, can be used for outdoor work, assembly of external door and window fillings, fastening decorations on a wooden facade.
Bonding strength reaches the strength of wood. The compound remains intact for many years.
Moment (from 300 r.)
Joiner's glue "Moment Super PVA D3" manufactured by Henkel has a Soviet analogue - DF51 / 15V. This is a good waterproof adhesive used for gluing paper, cardboard, plywood, and other materials of wood origin.
Water-resistant PVA is added as a plasticizing agent to concrete solutions to increase the ductility and water resistance of the working mass, finished stone. Connection with cement mortar increases adhesion to the surface to be screed or tile.
The letter D in the name indicates the degree of resistance of the material to water, 3 - a sufficient level. 4 - a higher class, used for special works, dear.
Titanium (from 200 p. For 500 ml)
Glue "Titan" is universal, reliably glues:
- plastics
- glass,
- paper
- wood.
They are often used for the manufacture of various wooden products.
"Titanium Universal" is a quick-drying adhesive suitable for working with wooden surfaces. It quickly gains strength, reliably connects surfaces without spoiling, and becomes transparent.
Mastic glue is suitable for finishing work, gluing wooden beams, boards, sockets.
Liquid nails are also compatible with wood, can be used for decoration and decorative elements.
Selection rules
It is necessary:
- Take into account the volume and specifics of the work. When processing large quantities of wood, it is better to give preference to powder semi-finished products because of their low price.
- Pay attention to the characteristics, select a solution according to physical properties.
- Find a suitable adhesive for consistency.
- Carefully read the information on the label, get acquainted with product reviews.
