Stairs have now become an indispensable facility in people's lives, especially solid wood stairs are favored by many consumers. So how should we pick a good staircase?
Due to the difference of the plates, the quality problems of the solid wood stairs are more than one year. The stairs with normal quality in one year will basically have no problems in the future. That's because untreated or only one-time drying pedals, when passed through the year, the difference in natural temperature changes will cause adverse reactions, such as mold, discoloration, deformation and so on. Therefore, many of the standard stair manufacturers only promise a half-year warranty. Home improvement owners should pay attention to the warranty period of the stairs for at least one year when purchasing solid wood stairs; for stairs that only promise half year warranty or no warranty at all, it is best not to buy.
Solid wood pedals are still the mainstream of the market. Strictly speaking, good stair treads must choose wood with low water content. Functionally, wood with low moisture content is not easily deformed after being stressed, which can ensure stability and safety. Of course, the material used as the stair tread must preferably be dried to directly affect the life of the stair.
Viton 23 is a copolymer of vinylidene fluoride and trifluoroethylene, commonly known as No. 1 rubber in China.
Fluorine rubber 26 is commonly called No. 2 rubber in China, DuPont brand fluorine rubber a, which is a copolymer of vinylidene fluoride and hexafluoropropylene, and its comprehensive performance is better than No. 1 rubber.
Fluoroelastomer 246, commonly known as the third largest rubber in China, DuPont Brand Fluoroelastomer B, is a terpolymer of vinylidene fluoride, tetrafluoroethylene and hexafluoropropylene, with fluorine content higher than 26 and good solvent resistance.
Fluoroelastomer TP, commonly known as tetrapropylene rubber, Asahi brand aflas, is a copolymer of tetrafluoroethylene and propylene hydrocarbons, which has excellent resistance to water vapor and alkali.
Vinylidene fluoride rubber, DuPont brand fluororubber, is a quaternary copolymer of vinylidene fluoride, tetrafluoroethylene, perfluoromethyl vinyl ether and vulcanization point monomer, with excellent low-temperature performance.
Perfluoroether rubber, DuPont Karez, has excellent high temperature resistance, high fluorine content, and excellent solvent resistance.
Fluorosilicone rubber has excellent low temperature performance and certain solvent resistance.
Fluoroelastomer is mainly used in automobile and automobile industry. It is mainly used for oil seal and O-ring due to its excellent high temperature resistance, oil resistance and medium resistance.
