First, the original paper:
Melamine impregnated paper is divided into three categories: plain paper and printing paper, and abrasion resistant paper. According to the product use, it can be divided into two categories: facial tissue and base paper. Plain paper has the difference between primary paper and printing paper. The original paper is the best, the color is pure, it is not easy to change color, and the color of printing paper is relatively uneven. Generally, plain printing paper is used as the bottom paper (multi-purpose laminate flooring, also called balance paper.)
Wood grain paper is printed on the basis of base paper. According to the realistic requirements of wood grain, the number of plate rolls used for printing varies.
Art Printing Paper: Among them, Senjia's art series is the most advanced.
Second, the ink:
Printing is indispensable for ink, and the ink used for melamine wood grain paper is water-based ink. There are domestic inks and imported inks. The main difference is the long-term problem of weatherability. To identify the quality of printing, you can use a magnifying glass to watch the number of "white". If you leave more white, it will affect the purity of the hue. In addition, the naked eye can see a lot of white, and the quality is very general. It is worthless. In addition, it is not allowed to have ink, and the color registration is not allowed.
If the color is browned, the ink quality is not good.
Third, the melamine content determines the wear quality of the melamine surface. Moisture proof, mold proof quality.
The best impregnated paper has a melamine content of 100%, followed by 70%, and most of the current use of 70% impregnated paper. Pure melamine impregnated paper has a shelf life of more than one year.
The worst number of non-influent sugar gums, acting as melamine glue, if exposed to the air for 5 minutes, immediately appeared to be bonded, so many people said to be placed in the air-conditioned room to prevent premature bonding and curing. Sugar, soluble in water, so it is not moisture-proof. It doesn't take long. Because of the wiping, the protective layer on the surface is easily wiped and melted. Therefore, in order to change this problem, the manufacturer of the sugar-adhesive paper adds a larger amount of curing agent, so there will be quality problems that will expire in a week or 15 days and be cured early. Simple detection method: put a wet towel on the veneer, and look at the surface changes the next day, whether it is a bubble or a bulge. Whether the surface gloss is destroyed after wiping.
There is a kind of impregnated paper, using urea-formaldehyde glue, the proportion of melamine is 60%, 50%, 40%, 30%. Although better than sugar, the shelf life is generally only 3 months, and some are less. The simple identification method is:
When the surface of the fire burns the board, there is a smell of urea.
The problem of formaldehyde release. The same has the difference between E1, E2, E0.
Fourth, the weight of paper (thickness)
Melamine paper is divided into many according to the color needs, printing needs, the need for impregnation and the need for use.
Category: Yes, 70 grams, 80 grams, 85 grams, 90 grams, 110 grams, 120 grams, 135 grams and so on.
Generally, the surface of the pressed titanium white noodles can be made 80 grams, but the matte surface will not work, and the bottom phenomenon will occur. Warm white, beige light matte surface no more than 110 will also produce a bottom phenomenon. And the production of 85 grams of psoriasis, 90 grams will be fine.
Five, curing agent
A simple melamine board also involves the problem of stain resistance. In addition to the difference in dipping glue, there is also an important factor that is the quality of the curing agent. There are imported and domestic distinctions.
Six, wear-resistant paper
The abrasion resistant paper is a melamine-impregnated overlay paper to which aluminum oxide is added. The abrasion resistant paper makes the surface of the laminate flooring bright and resistant to wear. It has the characteristics of high transparency, wear resistance, flawlessness, fire prevention and convenient maintenance.
The wear-resistant paper has 18 grams, 22 grams, 45 grams, etc., according to the different production processes, the wear resistance coefficient is also different. At present, wear-resistant paper is applied to laminate flooring. Good wear-resistant paper can withstand 6000 rpm test. Furniture boards are not currently in large use.
Seven, decorative base paper
The weight range is 70-110g/m2. Also known as "melamine impregnated paper, titanium white paper", the hiding power, weather resistance (color fastness) is excellent, the base paper is used for strengthening wood flooring, office furniture pressure plate after printing and dipping.
Eight, melamine impregnated film paper
Features: Can be used for the veneer of substrate such as particleboard, medium density fiberboard, or hardboard. And it has natural decorative effect and resistance, acid and alkali resistance, scratch resistance, corrosion resistance and easy cleaning. Protection: Store at a relative humidity of 55%-65% and a temperature of 10-30 °C.
Nine, there are paint paper, pu paper, etc.
The pre-impregnated paper and the post-impregnated paper can also be produced according to the different impregnation process and the use requirements. At present, some companies have begun to produce softened melamine impregnated paper that can be bent but not broken.
Therefore, the quality of the board is related to the quality of the wood-based panel itself, and also has a great relationship with the surface melamine impregnated paper. As a consumer, you can't covet cheapness as a basis for purchasing. It is recommended to know more about the relevant knowledge and good quality, which is a reliable product.
