When buying such conventional building materials such as flooring, be sure to pay attention to the many "traps" that exist in the market, such as immersing the material in water to show that it is not deformed by water. In fact, "not afraid of water" does not mean "no deformation". .

Xiaobian below for everyone to check out the 6 tips on the purchase of the floor, I hope to help everyone!

Floor purchase tips: water resistance

Poor water resistance will cause significant expansion around the floor, causing the floor to erect. Moisture content is an important factor that directly affects the dimensional stability of the floor. Generally, the moisture content of the wooden floor should be consistent with the local water content. Otherwise, the floor will have different dimensional changes when the environment changes, so we should pay attention to the purchase when buying. Whether the moisture content of the purchased floor meets the requirements of national standards.

Floor purchase tips 2: flame retardant

Since the flame retardant performance of the wooden floor cannot be required to be too high, a simple test method can be placed on the floor surface with a cigarette. After the end of the combustion, the floor is not burned and the non-clearing marks such as no cracks, dark spots, and bubbling are observed. Indicates that the flame retardant performance is acceptable

Floor purchase tips 3: Glue

The solid wood flooring is made of natural wood without any bonding. The solid wood composite floor is made by hot pressing of the adhesive coated surface, so the glue performance is an important quality indicator of the product, which will directly affect the function and life of the product.

Floor purchase tips 4: wear resistance

The laminate flooring has good wear resistance because it has a wear layer on its surface. The 6000-18000r we saw on the product description indicates the wear resistance, which also corresponds to the content of corundum abrasive in the wear layer. . National standards stipulate that products above 6000r are suitable for home use, while public places must be above 9000r.

Floor purchase tips 5: check the paint finish

Different from laminate flooring, the surface of solid wood flooring and parquet is processed by paint. When selecting, it should be checked to be uniform, smooth and smooth. No leaks, no bubbles, no cracks.

Floor purchase tips six: pay attention to formaldehyde content

Parquet and laminate flooring contain a certain amount of formaldehyde in the adhesive, which will gradually release into the surrounding environment in a gaseous form. When people are in a high concentration of formaldehyde, the eyes, nasal cavity and respiratory tract will be uncomfortable. Healthy body.

Tapered Roller Bearings

Tapered roller bearings are used in a variety of industrial applications. The tapered rollers allow the bearings to accommodate heavy radial, axial and combination loads. This loading flexibility combined with a variety of configurations can be designed from single cups, double cups, and cones. This is why tapered roller bearings are designed into almost every industry, particularly large diameter tapered roller bearings.

Tapered roller bearings are uniquely designed to manage both thrust and radial loads. Consisting of a "tapered cup" and a "tapered cone", this design is one of the most basic and common styles in the bearing industry. Found in everything from cars to conveyor lines, tapered roller bearings are more versatile than any other bearing series. Our taper bearings are sold in sets with both the cup and the cone together.

tapered roller bearings are designed for the most demanding applications in industries such as mining, forestry and steel manufacturing. Utilizing conical rollers and raceways arranged so that the rollers and raceways meet at a common apex, NTN`s tapered Roller Bearing rollers are guided by contact between the large end of the roller, providing high capacity for radial and single thrust loads. With almost 100 million tapered roller bearings manufactured every year under the NTN and Bower brands, it`s no wonder that NTN rivals all major competitors on the market.

We offer premium tapered roller bearings under the NTN and Bower® brand names. Most NTN and all Bower® tapered roller bearings feature case-carburized components. Cups, cones, and rollers are made from case-hardened alloy steel of [Bearing Quality" to provide superior fatigue life and reliability. Precise control of heat treatment, dimensions, and surface finish of the components further contribute to reliable bearing performance. So whether you`re looking for an American-made, case-carburized inch series taper, or a metric series through-hardened variety, we have you covered with a proper fit for your application. Premium steels and heat treatments are also available for applications requiring extended life and high reliability.
