Some customers want to take a lighter to light the SPC floor to see if it can burn. If it burns, 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, and the flame retardant raw materials are listed as class a fire safety according to the national standard,LavalHow to lay floor leather, 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,SPC floor does not use strong glue in the production process, so there is no indoor formaldehyde, benzene and other harmful substances. The real indoor formaldehyde low-carbon environmental protection floor has no damage to the body.The double composite solid wood floor adopts double-layer solid wood pressing. It feels like pure natural wood. The installation and maintenance is very simple. It is suitable for floor heating, beautiful and generous, good reliability, and contains a small amount of indoor formaldehyde.Upata,Ninth, laser cutting is simple and easy. Remove the pavement and remove dust to avoid the accumulation of crushed stones or friction coefficient floating dust on the floor surface.The shoe sole can be placed at the door to prevent broken stones or friction coefficient dust from being brought into the room.Generally, when cleaning the floor, you can wipe the road surface with cotton strips.Do not wipe the floor with wet mop or corrosive liquid (such as soap liquid and vehicle gasoline). In order to better improve the indoor air quality humidity, humidification equipment can be selected in autumn and winter to maintain the indoor air quality humidity at % - %.When moving furniture, you can tear it by hand. If it can be easily torn off, the tear strength of such ground lacquer cloth can not meet the requirements. After gently rolling up and pressing down, it indicates that the product layers are not well combined such a product has poor softness.If the layers can be torn by hand, and stratification will soon occur in future use.Plastic floor paint cloth has the advantages of light weight,LavalWhat brand of floor leather is good, elasticity, good mechanical strength, good foot feeling strength, comfortable foot feeling, wear resistance, pollution resistance, corrosion resistance, heat insulation, sound insulation, moisture resistance, small water absorption, good insulation, self extinguishing, easy cleaning, simple construction, convenient maintenance and low price. In a large number of civil buildings and public places, it has high requirements for cleanlinessIt is widely used in the laboratory.Plastic floor paint cloth belongs to soft floor. It is a floor coil produced by coating or calendering on sheet continuous substrate with polyvinyl chloride resin as the main raw material and appropriate additives.The length of each roll of plastic floor paint cloth is m ~ m, the width is mm ~ mm ~ mm, and the total thickness is mm (machine room) ~ mm (plant and public buildings)For 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 a comfortable and elegant feeling. If you want to use them for a short time or one-time cover, you can choose low-grade products, because low-grade productsThe price is low and 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. When checking the appearance quality of rubber plastic floor paint cloth, it should be under scattered sunlight or fluorescent lamp, and the illumination should be ( ± LX, LM from the tested sample, conduct oblique visual inspection. First, observe whether there are cracks, fractures and delaminations on the surface of the local lacquer cloth. If there are, it can be judged that the local lacquer cloth is unqualified. The second step is to observe whether there are wrinkle marks, bubble pollution points and pattern deformation. Those that cannot be observed are excellent products and first-class products; those that are slight but not obvious are recognized as qualified. Go back to the third step for observationIf there is any missing pattern on the surface of the ground lacquer cloth, or if there is any defect of the transparent wear-resistant film on the surface, it is the first-class product and the first-class product. If there is a slight missing print or lack of film, it is the qualified product, otherwise it is the unqualified product. Finally, carefully check whether there is deviation in the multi-color overprint on the surface, whether there is color difference in different parts, if the top-class product is uneven, if there are the above two defects, but if there is no obvious, it is the first-class productProducts that obviously have the above defects but do not affect the overall beauty are judged as qualified products. Finally, first smell whether it has pungent smell. There will be a slight smell after the good coil is opened, and the smell of inferior products is stronger; secondly calculate the use area, pattern and thickness. When purchasing and the same room should be selectedCoiled materials with the same batch number carefully observe the appearance quality, open a roll of ground lacquer cloth, separate the ends for a few meters, observe the surface layer of the sample, the surface layer is thick, and the service time is long, and then observe whether there are cracks, fractures, bubbles and large defects; whether the cross section is layered and cracked; whether the pattern is open, missing, lack of film and overprint deviationDefects such as color difference, color difference and pollution.
Fire protection: the fire rating of SPC floor is B, second only to stone. It will automatically extinguish after leaving the flame for seconds, flame retardant, non spontaneous combustion, and will not produce toxic and harmful gases.It is suitable for occasions with high fire protection requirements. The composite floor has stable quality and is not easy to be damaged.The quality of the solid wood composite board made of high-grade flowers, plants and trees can also be divided into good and bad. Therefore, it is best to select the solid wood composite floor guaranteed by a well-known brand, which can not only ensure the quality, but also deal with the problems of the store.Free consultation,Generally, the moisture content of non dry wooden keel is about %, and that of qualified wooden floor is generally about %. If the humidity difference is too large, the wooden floor is easy to absorb moisture quickly. If the time is long, the floor will arch up and the paint will crack.Therefore, it is best to choose dry and straight wood as keel.After the keel level is determined, the keel and floor can be fixed with nails.Third, it is flame retardant, but it cant be burned.The joint of the floor adopts the form of latch, which controls the vertical displacement of the floor and the horizontal displacement of the floor;The original tenon and groove type, which is often called tongue and groove floor, can only control the vertical displacement of the floor.No matter how early the wooden floor plate is, there is no tenon and groove at the joint, the floor plate often tilts up and stumbles when walking, which is inconvenient.
First, the wear resistance is not as thick as that of reinforced composite floor and double-layer composite floor;Management Department,In addition, pay attention to whether there are sawdust and stratification on the cutting surface of the plate and whether there are sawdust and stratification on the cutting surface of the solid wood floor. Check the hardness of the foundation ground.Color film layer: various decorative layers of wood grain, stone grain and carpet grain, which can meet the different needs of different occasions and different tastes.Laval, Beautiful and diverse colors,LavalWhat brand does laminate floor choose, seamless splicing construction, convenient and fast installation. Green environmental protection. SPC floor is a new floor material invented in response to national emission reduction. PVC resin, the main raw material of SPC floor, is an environmentally friendly and non-toxic renewable resource. It is free of formaldehyde, lead and benzene, heavy metals and carcinogens, soluble volatiles and radiation. It is truly natural environmental protection.SPC floor is a reusable ground material, which is of great significance to protect our earths natural resources and ecological environment.The raw materials of SPC floor are PVC (PVC) and calcium carbonate, which are thermally compounded by advanced technology. The production process is different from that of wooden floor, so its thermal expansion and cold contraction properties are also different;
