Furniture industry development, materials
At the moment, there is a dynamic development and improvement of the furniture industry. Every year, new raw materials and materials with an improved modified appearance and high performance characteristics appear for the production of furniture. Modern materials are conditionally classified into basic and additional. The main ones include: solid wood chipboard (particleboard / chipboard) MDF Additional materials include materials that are used as decorative cladding; they are responsible for the appearance of a presentable product. Abbreviation: what is what? To begin, we will analyze their official correct abbreviation: MDF is a finely divided fraction of a tree. ДСтП is a chipboard, a sheet composite material, which is used to conduct interior decoration. This is their complete correct reduction. LDStP is a laminated chipboard. Particleboard is a wood-laminated plate, a composite sheet material that is used only in the construction industry, for external use. It is made not only from wood shavings, but also from fractions of pumice, rubber, shavings of plastic, paper, acrylic. Builders and furniture manufacturers unofficially began to denote the same acronym for builders and furniture manufacturers, from which confusion arose. Therefore, we will leave in the text the abbreviation of chipboard for chipboard and particle board, which is familiar to all of us.
Particleboard and MDF: differences, similarities, pros and cons We offer to increase your awareness of the use of wood material MDF and particleboard in the manufacture of furniture. For the manufacture of MDF and chipboard, wood chips, shavings, sawdust are used. This is one and perhaps the only similarity of these materials. But even in this there is a difference: the difference between chips for chipboard and MDF looks like between products chopped by a meat grinder and products chopped by a blender, that is, a larger and smallest fraction. How are they similar, durable or not, because they are considered budget materials in the furniture industry. And in general - whether it is necessary to choose chipboard and MDF as the main material when ordering the manufacture of furniture for apartments and houses. Particleboard: emission class, grade, properties, application In the furniture industry of any category, there are regulated rules and regulations. Finished products must comply with international standards of safety and quality accepted in our country. Particleboard is made in the process when wood chips are hot pressed. Synthetic resins of organic compounds CH2O (formaldehyde), from 6 to 18% of the chip mass, are used as a binder. Due to the presence of organic compounds in the chipboard, the plates are of quality, strength and durability when used. In the furniture industry, only the first E1 is used, the second E2 is used very rarely: class E1 assumes the content of CH2O not> 10 mg in 100 grams of particleboard, this amount of substance is harmless to health class E2 assumes a content of CH2O not> 30 mg per 100 grams of particleboard. The emission class can only be determined in the laboratory. When buying a chipboard, check the class label on the stove. It is possible to find out which grade the chipboard belongs to by the quality of the surface of the plate itself. For example, the first grade of chipboard will always be with a smooth surface without defects. The second grade already comes with minimal scratches and chips. The third grade is already a marriage with a layered edge and severe defects. Particleboard properties: sheet thickness varies from 10 to 38 mm; used with relative humidity up to 10%; moisture absorption from 12 to 88%; heat transfer coefficient from 0.07 to 0.25 W / (mK) 0.06-022 kcal / (m - h - C); has a specific heat capacity of 1.7 to 1.9 kJ / (kg-K) 0.4-0.45 kcal / (kg-C); has a bending strength not <10-25 MPa.
Particleboard is often chosen for repairs and construction processes.
Furniture profiles, building partitions, panels for cladding, furniture for home and kitchen are made from them. In the manufacture of kitchen furniture, they are coated with a polymer resin, melamine film, laminated and a beautiful durable material for kitchen furniture is obtained. When laminating chipboard, its operational characteristics increase. So make chipboard. The melamine film prevents the evaporation of formaldehyde, and also ennobles the appearance of the plate and gives it aesthetics, repeats the texture of natural wood, stone, and metal, is covered with many types of laminate. Conclusion: chipboard is not expensive enough, chipboard has high endurance to the influence of high temperature, is moisture resistant due to the laminated coating, uniformity of the fabric, ease of processing, high resistance to chemical and physical influences. The disadvantage of chipboard and chipboard is its poor moisture resistance during prolonged contact with water, but this is fixable due to lamination. The presence of formaldehyde in their production is also considered a minus. But if you look, formaldehyde resins are present even in natural wood, it is impossible to completely get rid of them. Choose quality products from certified manufacturers. MDF: In the manufacture of MDF boards, a finely dispersed fraction of wood is used, it is mixed with organic or synthetic resins, paraffin, and lagin. This composition makes MDF an environmentally friendly material, as well as more flexible and smooth. Such substances are in a natural tree, they are safe for humans. The economical MDF can replace a natural solid wood and is not much inferior to it in quality. MDF reliability indicators are thickness and strength, resistance to deformation. They do not swell, do not deform in an aggressive and humid environment. These boards are called Medium Density Fibreboard. Furniture is made from MDF boards for the kitchen, bathroom, furniture for the home, it can be matte and glossy, embossed, with carved facades and smooth lines, doors and racks of boxes are also made from them. For status and respectability, MDF is finished with veneer. MDF is chosen for an even smooth surface, density, strength, but it is much heavier than chipboard and pricing is much higher. Therefore, it is best to make furniture as follows: for the case use chipboard, on the front of the facade or sliding doors it is better to use MDF.We conclude We tried to clearly explain the features of wood and materials for particleboard, chipboard and MDF. Everyone who chooses between these materials will certainly immediately feel the difference in price. Each material has its own advantages and features, so you need to choose the consumer, based on their goals and capabilities. If you want to hear our opinion, then our answer is better to choose an array of wood and MDF. The main thing is to choose a manufacturer who will provide you with a certificate of conformity, an international certificate of conformity and the conclusion of an GSE examination on your products.
