high concentration inhalation in the laboratory can cause nasopharyngeal tumors.However

High concentration formaldehyde is a genotoxic chemical.In animal experiments, SPC floor and plastic are not the same thing at all. SPC floor does not need glue in the production process, and does not have radiation. It is a green environmental protection decoration material and will not cause harm to human body.Charneca,When choosing laminate flooring, we should first see whether it is produced by regular manufacturers and whether there is an authoritative certification report;Secondly, open the moisture-proof layer of the floor, expose the substrate, smell the pungent smell, and the formaldehyde content is likely to exceed the standard.Usually the methods for measuring formaldehyde emission include perforation extraction method, look.Acacias,Wood plastic flooring manufacturer.jpg Main performance. Good wear resistance and stability

Identify from the packagePVC floor has ordinary floor raw materials, which can not be compared with the actual effect of sound insulation, and its sound insulation performance can reach - sound shells. Therefore, PVC floor is selected in the natural environment that must be quiet, school libraries, multi-al halls, cinemas, etc, shake the container containing floor wax first and stir it fully and evenly.Before waxing the wooden floor of the whole room, local trial must be carried out in inconspicuous places such as corners of the room to confirm whether there are abnormalities.In order to prevent floor wax from polluting walls, skirting lines and furniture, the above parts must be covered with adhesive tape paper.Fully soak the floor wax with a clean rag. It&#;s best not to fall off.Development Curriculum, In terms of foot feeling, solid wood is better than reinforcement. According to national industry standards, all solid wood is mm thick, and wood keel ceiling is selected for installation, so the upper foot is better than mm thick reinforcement plate.How to distinguish true and false solid wood flooring?In fact, of the inspection indexes of floor leather, such as wear resistance, water resistance, pollution resistance and flame resistance, are improved with the hardness of floor leather.Therefore, expert Construction: when purchasing floor leather, as long as the surface meets the wear-resistant requirements,CharnecaHow did you buy the floor leather, there is no need to demand softness, so as to facilitate the comprehensive improvement of other properties.Floor lacquer cloth (also known as floor leather and insulating floor rubber roll) is one of the indispensable or missing floor materials for the decoration of modern power distribution room, substation and communication room. It is not only beautiful and practical, but also has the characteristics of sound and moisture insulation, wear resistance and corrosion resistance. It can be used not only on the floor of living room, but also on the floor of workshop.The ground of the weak point machine room. Easy to clean: medical treatment is simple, bright as a new mouth, no stains, easy to clean.The surface paint of solid wood composite floor is very good, with good wear resistance, without excessive vitality maintenance.According to statistics, the solid wood composite floor prepared for the sales market will not be waxed within years, and the wind color of automobile coating will also be maintained.This is obviously compared with the maintenance of solid wood flooring.

The cross section of the floor is rubbed with a file, so that the heat generated in the cross section is the full volatilization of formaldehyde (formaldehyde will accelerate the release above ℃ and some irritating smell can be smelled). At this time,CharnecaMaterial of laminate floor, you can smell it. Generally, you can smell three different levels of smell:Equipment maintenance,The thickness of SPC floor is mainly selected according to personal needs.Of course, the floor thickness affects the floor price, and the service life will be different, but it does not mean that the thicker the floor is, the better. We need to select according to whether the installation will affect the door closing or other s;Whether the overall effect after installation will be uncoordinated;Material budget and other aspects to select the most appropriate floor thickness.PVC floor is generally between mm and mm thick, and the net weight per square meter is about -kg, which is less than % of the raw materials of general floor.In multi-storey buildings, it has incomparable advantages of load and saving indoor space.In addition, it has unique advantages in the renewal and transformation of old engineering buildings. Generally, wear-resistant paper with aluminum oxide content of about g / m is used, or wear-resistant paper is not used.Low density board (medium density board is rarely used), and the number of wear-resistant revolutions is usually between - revolutions.The edges and corners will be worn after being used for one or two years at most.With Hunan, Hubei, Shandong, Jilin and Heilongjiang as the gathering points, the suburbs of Beijing are still rampant.Low quality, not environmental protection, government departments are strictly investigating and dealing with it.Such illegal businesses only take into account short-term interests and have no after-sales service guarantee. The price ranges from to yuan.Charneca, The machining accuracy is poor, and it is often claimed that it is: imported large plate and domestic slotting.Three look serviceFor long-term indoor use, high and medium grade products should be selected, and products produced by well-known brands and regular enterprises should be purchased as far as possible. Such products have sufficient thickness and good interlayer adhesion, and are not easy to layer and curl, especially foamed leather, which gives people an elegant feeling. If you want to use them for short-term use or one-time cover, you can choose low-grade products, because the price of low-grade products is low, there are many prices to choose from, but many of these products are processed with waste materials, with poor flexibility, generally thin thickness and large shrinkage coefficient. Laminate flooring is generally composed of four layers of composite materials namely wear-resistant layer, decorative layer high-density substrate layer and balance (moisture proof)Laminate floor is also called impregnated paper laminated wood floor and laminate floor. Qualified laminate floor is made of one or more layers of special impregnated thermosetting amino resin.
