Wood grain paper furniture stickers manufacturers: furniture stickers will contain formaldehyde?


Wood grain stickers are generally used for high-grade furniture, speaker surface, desk, wood skin, hotel and interior decoration. wood paper furniture stickers factory: furniture stickers will have formaldehyde?

Furniture stickers contain formaldehyde, formaldehyde mainly exists in the glue of furniture stickers, try to buy better stickers. But if there are no children to live, adults don't have to worry too much. Ventilation for a while. Be sure to keep the room ventilated, especially when sleeping at night. Bedroom doors and windows should be opened to produce convection, so that the concentration of formaldehyde will not be too high to affect health.

The release rate of formaldehyde is related to the following four factors:

Indoor temperature, indoor relative humidity, indoor air circulation, loading capacity of indoor decoration materials. Under the conditions of high temperature, high humidity, negative pressure and high load, the release of formaldehyde will be intensified.

1. Indoor temperature

Since the boiling point of formaldehyde is 19, when the temperature exceeds 19, the volatilization rate of formaldehyde will increase by 0.4 times for every 1 increase in indoor temperature, especially when the temperature rises in summer or heating in winter, the concentration will even exceed the usual 4 times. That is, in spring and autumn, the formaldehyde in the testing room did not exceed the standard, while the formaldehyde in summer and winter exceeded the standard.

Now is the winter heating period, the indoor temperature after heating generally reaches more than 20. At this time, the formaldehyde hidden in the furniture will be released in large quantities.

2. Indoor relative humidity

The effect of humidity on formaldehyde is mainly because the urea-formaldehyde glue in the furniture board is produced by the polymerization of urea and formaldehyde. When the humidity increases, the urea-formaldehyde glue will decompose into urea and formaldehyde when the board is wet, thereby increasing the content of free formaldehyde in the board, resulting in an increase in the content of volatile formaldehyde in the air.

3. Indoor air circulation

Because the indoor formaldehyde release is a dynamic balance, when the indoor formaldehyde release concentration reaches an equilibrium value, the indoor formaldehyde is no longer released. At this time, we open windows for ventilation, breaking the balance value of formaldehyde, and the furniture will continuously release formaldehyde due to changes in indoor air circulation. So ventilation is a good way to accelerate the release of formaldehyde in furniture.

4. Loading degree of interior decoration materials

Indoor formaldehyde emission sources are not isolated, but widely come from decorative panels, furniture, mattresses, walls, floors and various decorative materials. Its formaldehyde content is the accumulation of various emission sources.

Depending on the release source, the volatilization time is also different. Formaldehyde in wall paint can volatilize in almost 7-15 days. Formaldehyde in wallpaper glue lasts more than 18 months, formaldehyde in large core board lasts 15 months to 5 years, and formaldehyde in MDF veneer lasts almost 3 years or even more than 10 years.

In addition, due to the mutual influence of the formaldehyde release rate of various formaldehyde release sources and the carrying capacity of indoor space decoration, the more complex the decoration, the slower the formaldehyde volatilization!

Introduction to the advantages of impregnated paper, come and collect!

Melamine impregnated paper is divided into three categories: plain paper, printing paper and wear-resistant paper. According to the product application, it can be divided into two categories: face paper and base paper. Ordinary paper is different from original color paper and printing paper. The base paper is good, pure in color, not easy to change color, and the color of printing paper is relatively uneven. Generally, plain printing paper is used as base paper (multi-purpose laminate flooring, also called balance paper), which is widely used in cabinets and laminate flooring.


Impregnated paper features introduced, quick collection!

Impregnated paper is a mixture of non-woven wood pulp and PE and plant fibers. It has good absorption and anti-dissolution ability. Impregnated paper is also a very economical paper towel with low particle shedding rate. What are the characteristics of impregnated paper? Let's analyze it together. Impregnated paper wear-resistant, rich styles, impact resistance, no deformation, pollution resistance, flame retardant, moisture-proof, environmental protection, do not fade, easy to install, easy to take care of, can be used for floor heating, etc.

What is the development history of melamine impregnated paper? Let's take a brief analysis. Melamine impregnated paper is generally used for panel furniture, most of which are low-pressure and short-cycle forms, that is, the board is made by pressing for tens of seconds under high temperature and high pressure. In recent years, the synchronous disk produced by combining gelatin paper with steel plate and wood grain has been loved by people because of its good body texture.

What are the main indicators of melamine impregnated paper? Let's make a brief analysis together. 1. The amount of glue: the solid resin content of the decorative film paper (expressed as a percentage (%)). 2. Volatile content: the content (percentage (%)) of volatiles (mostly moisture and other small molecules) on decorative film paper. 3. Pre-curing degree: The curing degree of the resin is expressed as a percentage (%) on the decorative film paper.

Melamine impregnated paper, also known as "melamine" paper, especially refers to the amino resin (melamine-formaldehyde resin and urea-formaldehyde resin) impregnated in solid color base paper or printed decorative paper, after a certain degree of drying, can be hot-pressed bonded together or bonded on the wood-based board substrate offset paper.
