Buy wood flooring
1. Before purchasing, you must first know the level, orientation, and area of ​​your home, and then select the wooden floor according to your local conditions. It is better to discuss the consensus of the whole family, and then determine the direction of the purchase of wooden floors; also consider the wooden floor The use of performance is temporary or long-term. Finally, we must consider our own economic ability and budget.
2. The types of wood flooring include: solid wood flooring, reinforced composite flooring, and solid wood composite flooring. First of all, what type of wood floor should be clearly selected, and then there will be a goal to select and choose.
3. After determining the type, it is necessary to further determine the species, color, grade, price, and specifications of the wooden floor suitable for your own home.
4. At present, the manufacturer of wood flooring on the market has a large number of brands that are dazzling and dizzying, and three products are everywhere. Therefore, when buying, be sure to know the brand and credibility of wooden floors, try to buy well-known brands of wood floors.
Through the investigation and research of the above steps, the types, colors, grades, prices, and specifications of wooden floors have been known, that is, the direction of purchase can be prepared for purchase.
Wooden floor shopping tips:
Smell smelling smells. High-quality laminate flooring usually has a heavier taste of wood. Cheap low-quality flooring is the opposite. If you smell it with your nose, you will have a strange smell, smoke your nose, and make people feel uncomfortable. Using this product will have negative health effects.
Test the water absorbency with clean water The quality of high-quality wood flooring substrate is very high, it is not easy to absorb water and damp, the simplest test method: pour the water on the substrate of the floor, it will not be absorbed, like water Beads float on the substrate as they flow. Low-quality, poor-quality flooring absorbs water, clear water disappears, and in life, it quickly expands and bubbling.
Observe the surface with the eyes to observe whether the density of the substrate is high density, medium density, or low density; whether the color is normal white, whether the wood surface particles are fine and smooth, and the wood surface particles are fine as the gray surface is the water-washed substrate, the structure , Density is far less than the dense density of Jiangxi Fuzhou Daya base material; wood grain is realistic, good quality flooring is usually imported wood grain paper around the sea, the lines are clear and beautiful, looks very warm, The low-to-medium-sized floor is generally a base material produced by a local small factory. The color is black, the grainy paper is not clear, and the grain is rather vague.
Test whether the cracks fit into the floor with high substrate density. No matter how long the time from the workshop to the warehouse, it will not swell, there will be no difference in geometric dimensions, the interface is smooth and smooth, and it looks like the whole board. It is floor that we put together.
Wood floor purchase points:
1, poor water resistance and water resistance will cause significant expansion around the floor, causing the floor to arch. Moisture content is an important factor directly affecting the dimensional stability of the floor. Usually the moisture content of the wooden floor should be consistent with the local moisture content. Otherwise, the floor will have different degrees of dimensional changes when the environment changes, so we should pay attention to the Whether the moisture content of the selected floor meets the requirements of the national standard.
2, flame retardant due to the flame retardant properties of wood flooring can not be asked too high, simple test method can be used to place on the floor surface, after the end of the burning, the floor is not burned out of the traces of irremovable if no cracks, Black spots and blisters indicate that the flame-retardant properties are satisfactory.
3. Glued solid wood flooring uses natural wood without any bonding treatment. The solid wood composite floor is made of hot pressed adhesive surface, so the adhesive performance is an important product quality index, will directly affect the product's use of function and life.
4, formaldehyde content solid wood flooring and laminate flooring in the adhesive contains a certain amount of formaldehyde, it will gradually release to the surrounding environment in a gaseous form, when people in a high concentration of formaldehyde, the eyes, nose and respiratory tract will Discomfort occurs and endangers your health.
5, wear resistance Laminate flooring has good wear resistance because it has a wear-resistant layer on the surface, we see in the product description 6000 ~ 18000r that wear resistance, which also corresponds to the wear layer The content of corundum abrasives. National standards stipulate that products above 6000r are suitable for home use, but in public places must be above 9000r.
6 The difference between varnish treatment and laminate flooring is that the surface of solid wood flooring and solid wood composite flooring is painted. When selecting, it should be checked that the paint surface should be uniform, smooth and smooth. No paint leakage, no bubbles, no cracks.
The petrolatum Anti-corrosion tape is made of plastic petrolatum ester, filler, paraffin oil, special preservatives, fillers, synthetic fibers and other raw materials. Gapless flexible ribbon roll. The petrolatum anti-corrosion tape can be used together with the petrolatum topcoat, the petrolatum cement and the polymer adhesive tape to form a complete anti-corrosion maintenance system.
The mineral ester anti-corrosion tape has stable properties, no curing, no hardening, no cracking, adapts to thermal expansion and contraction of workpieces with large temperature changes, has excellent plasticity and flexibility, contains volatiles within a safe range, and is harmful to the human body and the environment. No poison. It is suitable for anti-corrosion work of metal pipes and fittings, Flanges and Valves of any regular and irregular shape. It is widely used in gas, oil, water, petrochemical plants, urban construction, ships and other fields. It is also the first choice for anti-corrosion materials for steel pipelines, cast iron pipelines, joints, tees, elbows, refueling and refueling storage tanks, special-shaped prefabricated components (such as flanges, gate valves, tees, etc.), and edge plates of storage tank bases.
Scope of application
1. Pipeline anti-corrosion
From the pipelines inside and outside the factories of large-scale chemical companies, steel companies, and electric power companies, to equipment pipelines in high-rise buildings, and residential pipelines, whether it is overhead, ground, underground pipe gallery, buried or not in water, all pipelines can be used. Because it does not deteriorate even at the lowest temperature, it is suitable for corrosion protection of low temperature piping such as liquefied gas, and corrosion protection of cooling water and cold air piping.
2. Anti-corrosion of flanges, pipe fittings and welds
The petrolatum anti-corrosion system is a suitable anti-corrosion material for piping connections, valves, flanges, bolts, etc. Pipes pre-coated with plastic and bitumen, etc., can also be used for welds connected in the field.
Specifications of petrolatum anti-corrosion belt:
50mm x 10M, 75mm x 10M 100mm x 10M 150mm x 10M 200mm x 10M 300mm x 10M
The thickness and width of the tape can also be customized according to the user's specific design or construction requirements.
