What kinds of impregnated paper are used for melamine laminated wood based panels ?
Guide: The quality of the board is not only related to the quality of the wood-based panel itself, but also to the melamine impregnated paper on the surface.
1、 Base paper
Melamine impregnated paper is divided into plain paper, printing paper and wear-resistant paper. According to the use of the product, it can be divided into two categories: face paper and backing paper. Plain color paper is different from original color paper and printing paper. The original paper is the best, with pure hue, not easy to change color, and the color of printing paper is uneven Generally, plain printing paper is used as the base paper (laminate flooring is commonly used, also called balance paper), which is printed on the basis of base paper. According to the requirements of wood grain fidelity, the number of printing rollers used for printing is also different.
2、 Ink
Printing ink is indispensable. The ink used for melamine wood grain paper is water-based ink. There are domestic ink and imported ink. The main difference is the long duration of weather resistance. To identify the printing quality, you can use a magnifying glass to watch the amount of “white space”. If more white space is left, it will affect the purity of the hue. In addition, you can see a lot of white space with the naked eye, and the quality is very ordinary. worthless. In addition, it is not allowed to have ink support and inaccurate color registration. If the color is burnt yellow, the ink quality is poor.
III
Melamine content determines the wear resistance, moisture resistance and mildew resistance of melamine surface. The best quality impregnated paper has 100% melamine content, followed by 70%. At present, 70% impregnated paper is mostly used. The shelf life of pure melamine impregnated paper can reach more than 1 year. The worst kind of sugar glue is melamine glue. If it is exposed to the air for 5 minutes, it will be bonded immediately. Therefore, many people say that it should be placed in the air-conditioned room to prevent early bonding and curing. Sugar is soluble in water, so it is not moisture-proof. It won’t be long before the protective layer on the surface is easily melted due to wiping. Therefore, in order to change this problem, the manufacturer of gummed paper adds more curing agent, so the quality problem of early curing will occur, which will expire in a week or 15 days. Simple detection method: put a wet towel on the panel, and check the change of the surface the next day to see if there are bubbles and bulges. Whether the surface gloss is damaged after wiping. There is a kind of impregnated paper, which uses urea formaldehyde adhesive. The proportion of melamine is 60%, 50%, 40%, 30%. Although it is better than sugar gum, the shelf life can only reach 3 months, and some are even less. The simple identification method is: when the fire burns the surface of the board. There is a smell of urea. Formaldehyde emission. There are also differences between E1, E2 and E0.
4、 Paper weight (thickness)
Melamine paper can be divided into many categories according to the needs of color, printing, impregnation yield and use: 70g, 80g, 85g, 90g, 110g, 120g, 135g, etc. Generally, 80 grams of domestic titanium white linen laminated wood based panels is enough, but it is not enough to press the matt surface, which will cause the phenomenon of bottom penetration. Warm white and beige matt finish without more than 110 will also produce bottom penetration. The 85 g and 90 g of pitted noodles can be used.
5、 Curing agent
A simple melamine board also involves the problem of stain resistance. In addition to the difference of dipping glue, there is also an important factor, that is, the quality of curing agent. There is a difference between imported and domestic
6、 Wear-resistant paper
Wear resistant paper is a kind of melamine impregnated paper with aluminum oxide. The wear-resistant paper makes the surface of the reinforced composite floor bright and wear-resistant. It has the characteristics of high transparency, wear resistance, flawless, fireproof, convenient maintenance, etc. There are 18g, 22g and 45g wear-resistant paper. The wear-resistant coefficient varies according to the production process. At present, wear-resistant paper is widely used in laminate flooring. Good abrasion resistant paper can withstand the test of 6000 revolutions. The furniture board is not widely used at present.
7、 Decorative base paper
The range of gram weight is 70 ～ 110g/m2. Also known as “melamine impregnated paper and titanium white paper”, it has excellent covering power and weather resistance (color fastness). After printing and dipping, the base paper is used for laminate flooring, office furniture pressing plate, etc.
8、 Melamine impregnated paper
Features: It can be used for laminated wood based panels of base materials such as particle board, medium density fiberboard, or hard fiberboard. And it has the advantages of natural decorative effect, damage resistance, acid and alkali resistance, scratch resistance, corrosion resistance, easy cleaning, etc. Protection: It shall be stored under the conditions of 55% 65% relative humidity, 10 ℃～ 30 ℃.
9、 Paint paper, pu paper, etc
According to different impregnation processes and use requirements, pre impregnated paper and post impregnated paper can also be produced. At present, some enterprises have begun to produce softened melamine impregnated paper, which can be bent but not broken. Therefore, the quality of the board is related to the quality of the wood-based panel itself, as well as the melamine impregnated paper on the surface that can be bent but not broken. Therefore, the quality of the board is not only related to the quality of the wood-based panel itself, but also to the melamine impregnated paper on the surface. As a consumer, we should not take cheap as the basis for purchasing. It is recommended to learn more and consult more about relevant knowledge. Good quality is the reliable product.
