Bookbinding cardboard: characteristics and application
Many needlewomen are familiar with cardboard firsthand. Lovers of fashionable scrapbooking today do not know how to replace this material. But cardboard is not just thick paper; various technologies allow this fibrous material to be produced for a wide range of uses.
A bit of history
His appearanceand productionthe material is obliged to print when, along with wooden and leather coversbegan to uselightweight and durable materials made from glued paper.The first mentions of the fibrous material, the structure resembling cardboard, belong to ancient Egypt, however, they still did not know about paper books and used the material for burial purposes.
On the edgeXVIII-XIXcenturies, when the production of material only developed, cardboard packaging began to be produced as a separate product by request of pharmacists, confectioners and jewelers.
Modern manufacturers distinguish 6 classes of cardboard:
- packaging - the most affordable and unpretentious in manufacturing;
- polygraphic - cardboard binding, used for the original purpose;
- shoe, or suitcase;
- technical, with various special properties;
- construction, which is used in composite materials.
Cardboard is good because its parameters can be controlled using various types of raw materials and degrees of compaction. Also these fibrous plates are an environmentally friendly material, using which recyclable materials can be used. In many developed countries, recycling of cardboard packaging is encouraged with a view to its further processing.
The main parameters of the cardboard are its density (measured in the weight of 1 square meter of material) and thickness. Among the additional characteristics, tensile strength and bending, humidity, insulating properties, including dielectric, have a different degree of importance.
Modern Printing and Handicraft
Among the fibrous materials used in the printing industry, there are several subspecies:
Presspan - cardboard, made with a high degree of compaction, additionally processed on special equipment to impart gloss. It has high density and mechanical strength.
The matrix view is used for the manufacture of forms with which you can get copies of the set. The basis of this cardboard is sulphite pulp, as well as other substances that impart heat resistance and strength.
Bookbinding cardboard is made entirely of brown wood pulp. In some brands it is possible to partially replace raw materials for waste paper.
Binding cardboard 2 mm thick is most often used for the manufacture of book covers, as well as in the manufacture of especially large puzzles and other children's play equipment. Due to coarse fibers and porous structure, the material does not exfoliate and holds glue well, therefore offset paper, leather and other materials are firmly fixed on the flat surface of the material.
Cardboard binding 1 mm is used by needlewomen as a surface for drawing pictures and applying applications, as well as as a basis for bulk items.Sheets of this thickness are used in many items in scrapbooking and decorative gift wrapping.
Work with material
Scissors are not the most convenient tool for working with bookbinding cardboard; they deform the edges of the cut. It is much more convenient to use a roller knife or its prototype for threading, as well as a rigid ruler to control the progress of the blade. It is important to consider the location of the fibers when planning products made from fibrous sheets. Along the fibers fold can be made without prior punching, and even a thick plate will not be folded with a crease.
In general, the binding cardboard is produced in sheets with a thickness of 0.5 to 3 mm, which allows it to be used in a variety of applications in handicraft. Folds of such cardboard usually do not burst, the material absorbs moisture well. Due to natural raw materials, the binding cardboard has a characteristic brown color. Available A4 - A2 format paperboard binding can be found in stationery stores. Other formats are not so popular, so you can buy them only in specialized stores for needlewomen or in print shops.
