Detection of wood from resin in steel sofas
resin in steel sofas
In recent years, we have seen that some manufacturers use polyester resin instead of wood in earrings and inlays of steel furniture. Due to the fact that the difference between wood and resin is very much, we will share information with you so that you can distinguish wood from resin when buying a steel sofa.
What is Polyester Resin?
It is a combination of plastic that is used in various industries, including the furniture industry. This material is also known as fiberglass, but in fact it is a kind of reinforcing fiberglass and polyester is a kind of gum called resin. When polyester resin is mixed in a dryer (hardener), its temperature rises and the state takes on a jelly and eventually turns into a hard substance. After hardening, the volume of the polyester resin decreases to some extent, and this is because the molecules get closer to each other during the hardening of the resin in the jelly state, and also some of the solution evaporates. Hardened polyester resin can never be returned to the liquid state.
Resin and wood, differences and methods of distinguishing them from each other
Since in furniture parts made of resin are covered by paint from our point of view, how can we distinguish them from wood?
The easiest solution for you is to ask the seller so that you can see the unpainted sample of the sofa inlay. But if this is not possible for you and the furniture is delivered to you in a completed and painted form, do not worry, at this stage you also have solutions to distinguish wood from resin.
In this section, you have two ways to distinguish between the two:
- Insert the needle into the fabric of the sofa with some pressure. If the needle entered the fabric, then the sofa is made of wood, but if you did not manage to insert the needle into the fabric, it is likely that polyester resin was used to make the sofa.
- The next method is to use a hot needle. In this way, you can insert the hot needle in a part of the sofa, if you feel the smell of plastic after doing this, the sofa is made of resin.
Be careful when choosing these methods to choose parts that do not damage the appearance of the furniture. The inlaid part of the sofa is the best place to do this test, because wood has recently been used in making the base of polyester sofas.
Also, polyester resin has more weight than wood, and furniture produced with resin is heavier than wooden sofas, and also the color on the resin material is not transparent, and the colors are generally matte, opaque and of low quality.
Advantages of using resin
One of the most important advantages of using polyester resin is easy production and thus lowering the cost of the product.
The best temperature for working with polyester resin is twenty degrees. This substance has a pungent smell in liquid form and its daily consumption of more than five kilograms in a well-ventilated space is harmful to health.
Polyester resin is used in the fields of woodcarving, molding and delicate designs. Like many materials, polyester resin has different qualities, and if you want to spend less on steel furniture, if you use quality materials, you can have good quality furniture, beautiful and affordable design that against Factors such as premature failure and decay are resistant. But it should also be noted that the resin with the best and highest quality can’t replace wood in any way.
Disadvantages of using resin
Apart from poor quality and matte paint, as well as the high weight of resin furniture, improper use of this material leads to severe cracking, scaling of inlays and fragility.
Our advice to you, dear reader, is to buy furniture made of wood as much as possible. Polyester resin is a chemical substance, which is the best type of low-quality furniture.
