First, pay attention to product name and environmental protection index At present, the product name of solid wood composite flooring on the national market is mixed, dazzling, resulting in many consumers can not choose, and in fact the national standard provides a unified standard name "solid wood flooring." Due to the production process of solid wood composite flooring products, adhesives harmful to human health, such as formaldehyde, may be used. If the content of harmful substances in such adhesives exceeds the national standards, it will have an impact on human health. Therefore, both manufacturers and consumers Attention should be paid to the environmental protection indicators of solid wood composite flooring, and formaldehyde emission from solid wood composite flooring should meet the national mandatory standards.
Second, the purchase of well-known brand products in the purchase of solid wood flooring, to choose a good reputation brand-name products, give priority to choose the country or industry related departments identified products, such as national inspection-free products, Chinese well-known trademarks and Chinese famous brand products. Do not buy "Three Nothing" products, and be careful to buy "Full Foreign Language Packaging" products. If it is imported goods, it should have Chinese identification and import documents; it can not only be cheap but purchase products with low prices.
Third, pay attention to the stability of the floor and the floor glue performance, although the stability is good solid wood flooring flooring, the outstanding advantages, but the improper control of moisture content or unscientific pavement, will also affect the stability of the product. Therefore, consumers should pay attention to the moisture content index and paving method of solid wood flooring to ensure stability. Solid wood laminate flooring is a floor made of several layers of wood glued together. The better the glueability, the longer the service life of the flooring, the more durable it is, and the easier it is to maintain.
Fourth, pay attention to the performance parameters of the floor paint Because solid wood flooring is difficult to distinguish between the appearance of the quality of the product is good or bad, only to understand the inherent technical parameters of solid wood flooring, in order to really buy high-quality products. The main technical parameters of solid wood floor paint include the adhesion of the paint film on the floor, the wear resistance of the paint, the paint treatment process (how many paint processes are processed, etc.), and the hardness of the paint film. In general, the harder the paint is, the better the paint adhesion is, the longer the service life of the floor is.
Fifth, consumers buy solid wood flooring, be sure to follow the principle of "whoever sells"
While following the principle of “whoever sells and who will layâ€, consumers should also ensure that the seller has the following conditions: 1. Have a regular construction team and have good construction experience; 2. The construction team has a good image and construction management standards; 3 There are perfect paving rules.

Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Alcohol Mass Flow Meter, Alcohol Mass Flowmeter, Alcohol Coriolis Meter, Mass Flow Meter Alcohol, Coriolis Mass Meter Alcohol, ATEX, IECEx & CE approved.
Sealand meter is designed and produced according to world`s latest Coriolis technology with better appearance, stability and accuracy to measure mass flow rate of a fluid traveling through a tube, widely applied to alternative energy, oil & gas, chemical, food & beverage, industrial energy, marine, power, pulp & paper, water & wastewater industries, etc.
Mass flow meter measures the mass based on Coriolis effort. The operating principle involves inducing a vibration of the tube through which the fluid passes. The vibration, though not completely circular, provides the rotating reference frame that gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift & amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid.
