Q: F grade sheet and EO-class plate, what is the difference between these two, Guiqiu master answer, buy a furniture to the market a question, really a headache? Which is good?: These are the measures that measure the amount of formaldehyde released by the furniture and are environmentally friendly F4 star is a new upgrade of environmental standards, compared to E0 should be more advantages. ? The so-called F4 star standard, in fact, Japan's "F ☆ ☆ ☆ ☆ certification standard" F4 Star "is the highest standard of Japanese floor standards of health, but also considered the world's most healthy floor standards.If the usual E1, E0 Standard, then the "F3 star" is equivalent to the national E0 level standard, the proposed limit the use of area, "F4 star" is much higher than the "F3 star", the use of unlimited area. The standard applies to sheet, floor, Cabinets, furniture and other wooden building materials products.

Q: Shang material home furnishings with the plate is what material: Shangpin furniture with furniture is a medium density fiberboard, formaldehyde content is far lower than the national E1 level standards, the relevant standards close to the European E0 level standards. Plate furniture environmental protection, wear resistance, fire resistance, acid and alkali are higher than the traditional solid wood furniture: 1. Environmental protection: good plate furniture used for the quality of the substrate for the high-quality wood, the use of high environmental protection and glue with less, mainly by high-pressure raw materials forming a surface of the use of environmentally friendly melamine fire materials, without any volatile Gas release. Solid wood furniture surface is sprayed with colored paint, and paint is containing formaldehyde, benzene and other harmful gases, any kind of paint contains these harmful gases, but how much of the problem. Poor solid wood furniture is the use of non-compliance of the paint, the production of some of the furniture with a few years there are obvious irritating smell. 2. Wear resistance: melamine resin is a very high hardness of the material, the general metal will not leave scratches in the above, and paint is a soft texture of the material, it is easy to draw flowers, not wear. 3. Fire: melamine resin itself is a fireproof material, do not help combustion. The paint is a kind of easy to burn the material, not fire. 4. Acid and alkali resistance: melamine resin has a certain acid and alkali resistance, the general acid and alkali will not damage its surface. The physical properties of the paint are not very stable easily by acid-base burns, loss of surface brightness or even stripping.

Q: Millennium boat plate fake, how to identify.: Identification of millennium boat plate method is as follows: View, contrast mark. Millennium boat plate above the level of signs, E0, E1 have such a look like you. Look at the fineness of the sheet. E0, E1, E2 is the limit level of formaldehyde release in plywood, the difference is E2 grade formaldehyde emission ≤ 5.0mg / L; E1 grade formaldehyde emission ≤ 1.5mg / L; E0 grade formaldehyde emission ≤ 0.5mg / L. In the actual use of the difference is: E2 level can not be directly used for indoor, E1 level can be used directly for indoor use, but the use of limited, E0 level can be used indoors. Compared with E1, E2 plate, E0 board has the following characteristics: The first type of rubber is different: E0 sheet of the reason why environmental performance is excellent, there is a large extent reflected in the glue, the general plate, including E1 grade plate are used aldehyde glue, and E0 grade plate is generally used water-based polymer glue, Is no aldehyde glue. The second drying method is different: the best common plate can only do the core bar drying, and E0 grade plate used in the plate are steam drying, so that the moisture content can be reduced to the lowest, favorable and plate maintenance. Third: E0-class plate in the production process in addition to the use of formaldehyde-free glue, and do not use benzene, phenol and other harmful substances in the material, the plate can improve the environmental performance of a step.

Q: Is there any color of a decorated panel: There are many types of ornaments, such as white oak, safflower pear, red oak, etc., each color, pattern is not the same, to choose a wide surface, you can meet the different preferences.

Q: What is the integrated ceiling UV board: 1. UV board is the surface after UV treatment to protect the plate. UV paint that is UV light curing paint, also known as light-induced paint. In the particleboard, MDF and other sheet on the UV paint, and then through the UV light curing machine and the formation of the plate, because of its easy processing, can achieve industrial production, bright color, wear resistance, chemical resistance, long service life, The mechanical equipment and process technology requirements, and has the characteristics of anti-humidity anti-deformation: Primer with solvent-free 4E green high-grade paint, not volatile, non-toxic environmental protection; cured with high light antibacterial effect of the ideal decorative plate. 2. Integrated ceiling is HUV metal square board and electrical combination. Sub-board module, heating module, lighting module, ventilation module. With the installation is simple, flexible layout, easy maintenance, a bathroom, kitchen ceiling of the mainstream. Today, with the growing development of the ceiling industry, balcony ceiling, restaurant ceiling, living room ceiling, aisle and so on are gradually becoming the mainstream of home improvement. In order to change the monotonous lack of ceiling color, integrated art ceilings are becoming the market trendy.

Q: Is the board of the coastal wood grade the E0 grade sheet? E0 level with E1 grade plate What is the difference?: Coastal wood sheet has E0 grade plate. E0 / E1 / E2 and the difference: In 2004, in the national standard (GB / T9846.1-9846.8-2004), marked the E0 ≤ 0.5mg / L limit level, E0 level is China and the international caravan board and its products in the formaldehyde emission limit The highest standards; December 10, 2001, the State Administration of Quality Supervision, Inspection and Quarantine issued a "interior decoration materials man-made board and its products in the formaldehyde release limit" (GB / T18580-2001), marked E1 ≤ 1.5mg / L limit Level, the provisions of E1-class products can be directly used for indoor; December 10, 2001, the State Administration of Quality Supervision, Inspection and Quarantine issued a "interior decoration materials, wood-based panels and their products in the formaldehyde release limit" (GB18580-2001) marked E2 ≤ 5mg / L, E1 ≤ 1.5mg / L two limited levels, the provisions of E1-level products can be used directly for indoor. E2 grade products must be finishes before they can be used indoors. Last year, the "plywood" national standard GB / T9846.1-9846.8-2004 inside the formaldehyde limit level is divided into three levels, namely E2 ≤ 5.0mg / L, E1 ≤ 1.5 mg / L, E0 ≤ 0.5 mg / L. E1 is a national mandatory health standard, it is mandatory "safety standard line". E0 standard is the current international high health standards. Because the 0.5mg / l formaldehyde content is already a very safe numerical standard. According to the relevant data show that the formaldehyde content of drinking water is 0.9mg / l, ????In other words, E0 standard formaldehyde content is less than drinking water. Environmental protection products with high levels of natural prices should be high in the production cost is certainly high.

Q: How about the environmental protection grade of the furniture sheet? What is the effect on the furniture?: Domestic plate environmental protection level to borrow the European standard: E0 level, E1 level ..... E0 level best! Plate emissions of harmful gases on the human body, such as formaldehyde, benzene ... and other levels of emissions standards! (Domestic plate also marked AAA or AA, AAA better, not vulnerable to moisture deformation) The environmental protection grade of the plate has no effect on the craft and the production process of making the furniture!

Q: Are plates p2 and e0 almost?: In the purchase process, as long as optimistic about the level of formaldehyde release board on the line. E0 best, E1 times, E2 has been rarely used. Southeast wood manufacturers have super E0 board, formaldehyde release even less, but also by the United States California certification p2 plate. CAPB P2 level is higher

Q: How about the top 100 board furniture: Bought his family more than seven thousand yuan of plate, the price of high quality times. Just received the goods, a look at selling good, knock knock, the sound is crisp, touch very smooth, very texture. Well, hundred of the brand, very good.
