it is not fire safety, and if it doesnt burn, it is flame retardant.In fact, the national regulations on the flame retardant grade of PVC latch floor meet the B Standard,BrooklynSolid wood composite solid wood floor, and the flame retardant raw materials are listed as class a fire safety according to the national standard, such as marble, wall tiles, etc.The technology of Class B flame retardant grade includes mm diameter cotton wool, sprinkled with ethanol, and placed on the PVC latch floor for natural ignition. After the cotton wool is burned accurately measure the diameter of the burned PVC latch floor impression. If it is less than mm, it is Class B flame retardant grade.Instead of watching it burn. Look at the section of the board.Brooklyn,Disadvantages of reinforced composite wood floor.In this category, it can be shown that it is a relatively safe commodity.In addition, it should be noted that the release of formaldehyde must take a whole process of time. The formaldehyde content tested at this stage does not represent the long-term formaldehyde content.Douhu,First, look at environmental protectionFour look at the brandThe first is cleaning to remove oil stains or dust;The second is leveling. The convex part shall be shoveled and polished. The concave part can be made into paste with glue and cement at the weight ratio of :, leveled with a spatula, and then leveled with sandpaper after drying.After the ground is flat, clean and dry, it can be glued and paved.Gluing is the last process before paving, and the tool shall be a toothed rubber scraper.During gluing, glue shall be applied on the ground according to the size of the floor paint cloth and one piece shall be paved in this order.A width of cm shall be reserved at the joint of the floor paint cloth. No glue shall be applied first, so that the joint can be treated finally.When the glue coated on the ground feels sticky by hand it can be paved. When pasting, pay attention to aligning the sidelines, and use a long handle floor brush to blow out and compact.The joints are generally spliced by overlapping cutting, and the overlapping width is about cm.Align the long steel ruler with the center of the overlap, cut with a cutter along the ruler, then remove the cut edge strips (note that there should be two edge strips, dont forget to take out the lower one), apply an appropriate amount of glue to the joint with a paint brush, use a syringe to insert and suck out the air check whether there are bubbles and whether they are flat.If there are bubbles, and then compact it.Finally, use washing powder to remove the residual glue marks on the lacquer cloth. If they cannot be removed, they can be wiped with alcohol.In this way, the whole process will be completed.Due to the improvement of the living standards of Chinese residents, the grade of interior decoration is also rising, and the decoration materials are increasingly developing towards the fixed decoration direction of elegance, high profile, long service life and good effect.As for the ground, the service life of paint, carpet or ordinary floor leather and floor brick is not as long as that of ground lacquer cloth.

The first kind: pungent taste. If the floor tastes like this, it means that it contains a lot of formaldehyde. You need to be careful when choosing. Youd better not buy it;Secondly, we should pay attention to the basic defects on the floor surface, such as whether the floor has cracks, traces of decay, loose knots, whether the floor is bent, etc.However, the color difference of the plate surface has nothing to do with the quality of the floor.Generally speaking, due to the different growth environment, the texture and color of wood are also different.We dont have to be too strict about color difference and texture.This is the natural property of wood.The quality and color of the floor coating surface is also a very important part. The coating film on the surface of the hot solid wood floor is not allowed to be injured or blistered. In terms of the comprehensive performance of the coating surface, it is generally better than the product quality of UVB coating.In family life, maintaining the floor is essential as if women take time to take care of their skin or keep healthy every day, and the scratches on the floor are like brilliant sadness in youth, so they must have good maintenance habits.Now, long service life, simplicity, elegance and other advantages.However, how to repair the scratched solid wood floor? Do not scrape or scratch the floor surface with sharp tools.Quality risk, Green environmental protection Super wear-resistant. The wear-resistant layer on the surface of SPC floor is a transparent wear-resistant layer processed by high technology, and its wear-resistant revolution can reach about revolutions.According to the thickness of wear-resistant layer, the service life of SPC floor is more than - years.SPC floor is a long-life floor, especially suitable for public places with large flow of people and high degree of wear.Finally, the plate has a certain degree of expansion, so some gaps (.mm is appropriate) should be left between the laths during splicing to avoid arching.If the floor of the room is uneven, it can be paved with wooden keel for leveling, and then nailed with lath on it. After planing, paint and wax can make the room elegant, extraordinary, clean and warm.A short wooden floor strip has been launched in the market, which can be combined freely according to the size of the room, and can be assembled into a variety of patterns at will.This kind of short plank is more practical, but the disadvantage is that the cost is not low.If the floor is made of wood, the wallboard can also be decorated with plates, so that the overall structure of the room tends to be unified.Wall panels can be used as whole wall paneling or only as dado paneling.Wood wallboard is the best for large wallboard concrete wall. It can directly fix the board to the wall with adhesive.If the white ash interior wall of brickwork structure is decorated with wallboard, it shall be fixed for minutes first×mm vertical wood wall reinforcement, and then fix the plate to the wood wall reinforcement with wood screws.Family decorative wallboard is best based on plywood,BrooklynWaterproof board of railway tunnel, and its strength is appropriate.Then stick wood veneer on its surface to make up for the deficiency of plywood pattern.After the veneer is pasted, apply one or two layers of matte paint and the pattern of the wallboard will be clear and beautiful, smooth and three-dimensional.Wood floor and wood wallboard interweave, making the style of the whole room unified, both simple and elegant.On the basis of uniform color or reasonable interweaving, it can make the whole room comfortable and soft, and give people an indescribable sense of mystery.Introduction of floor leatherproduction costs, which is often made of pine, fir and other softwood.Birch: good toughness, most low-grade materials.Common types: three-layer solid wood composite floor, double-layer solid wood composite floor, new solid wood composite board.Brooklyn, Wear resistance, wear resistance grade t.From the perspective of environmental protection, the thin one is better than the thick one. Because the thin one uses less glue per unit area. The thick one has less density than the thin one, and the impact resistance is poor, but the foot feel is slightly better. In fact, there is little difference between the two. In fact,BrooklynWaterproof board microwave welding machine, there is no difference between the thickness and quality of the two kinds of floors. The key is to see personal choice.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, 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.
