Second, select the substrate. High-density fiberboard as the main component of the reinforced composite flooring substrate, its density should not be less than 0.8g/cm3, the thickness of the substrate should meet the international standard of 8mm, or too thin will affect the solidity, too thick will easily deform.
Third, look at the amount of formaldehyde released. The amount of formaldehyde released from the green building materials stipulated by the international environmental protection organization is not higher than 9 mg/100 g. Consumers should try to choose products that are lower than this standard when they choose to laminate flooring.
Fourth, look at the surface wear resistance. The wear-resistance grade of household laminate flooring should be AC3 grade (ie the initial surface wear resistance value should be above 6,000 rpm), and the initial wear resistance value of the surface of the laminate flooring applied in public places should be above 9,000 rpm. All laminate floorings should have inspection reports issued by national authorities.
Fifth, look at measures against moisture. Whether there is a special moisture-proof floor mat, whether there is a thick damp-proof layer on the laminate floor, and whether professional floor waterproof glue is used will directly affect the moisture-proof performance of the product.
Sixth, looking after-sales service, thoughtful and comprehensive after-sales service is not only a full reflection of the company's strength, but also an important part of the product quality. It plays a decisive role in whether consumers can rest assured and feel comfortable using the product.

A laboratory overhead stirrer is a device used in chemistry and biology laboratories to mix and stir liquids. It consists of a motor that drives a rotating shaft with a stirring blade or paddle attached to the end. The motor is mounted on a stand that is suspended from the ceiling, hence the name "overhead stirrer". The stirring speed can be adjusted by the user, and the device can be programmed to run for a set period of time. Overhead stirrers are commonly used in chemical synthesis, cell culture, and microbiology applications. They are particularly useful for mixing viscous liquids, suspensions, and emulsions, and for maintaining a consistent mixing speed over long periods of time.
