There are a large number of solid wood floors in the market covered with a large building materials market, which looks good at first glance. Light can tell people, different wood, then how to distinguish between high school and low in so many solid wood floors? What misunderstandings are easy to fall into when choosing solid wood flooring?

First, tree species wood floor

There are many types of trees that can produce floorboards. There are precious rosewood and teak wood; in general, there are eucalyptus wood, eucalyptus wood, manchurian ash, and gancrop. There are inexpensive pines and pines, and the price difference is very large. Misleading tree species names on the market are very common. Consumers can check the commonly used wooden flooring business name issued by the China Forest Products Industry Association Flooring Committee, or select their favorite tree species, texture, and color. Select the dyeing board, try to select the stable species of wood to avoid scooping, twisting, bending, cracking, arching and ringing during the long-term use of the wood floor.

Second, choose the size

The solid wood floors currently available on the market are all long and wide in size, such as 900 mm x 90 mm x 18 mm. In fact, the wooden floor should not be short and should not be narrow, should choose less than 600 mm × 75 mm × 18 mm floor, the smaller the size, the stronger the ability to resist deformation. If you like the long, you can use the ground plate, up to 4000 mm, like the wide optional integrated floor, up to 220 mm: the width of the floor should have anti-deformation groove, the groove depth should be more than one third of the floor thickness . If used for floor heating floor, should not be thick, generally 8 mm-12 mm.

Third, choose the moisture content wooden floor

The moisture content is crucial. The moisture content of the purchased floor must be consistent with the local equilibrium moisture content. Buy the floor must determine the moisture content, if the seller does not have moisture meter, do not buy its board. The method of measuring the equilibrium moisture content is very simple. In the exhibition hall, the moisture content of the purchased varieties is first determined, and then the moisture content of the wooden floor of the purchased varieties is checked out. If the moisture content of the two varieties is only 1%-2%, it is a qualified product.

Fourth, the selection processing accuracy

With 10 floors assembled on the ground, hand touch, seeing the accuracy of its processing, finish is smooth, smooth, rake, slot fit, installation gaps, anti-deformation tanks and other assembly is tight.

Fifth, choose the quality of the substrate

Check the level of the floor, whether there are bugs such as insect eyes, cracks, decay, blue changes, dead knots, etc. For small living quarters, color difference can not be too demanding, this is a natural property of wood, as for the natural texture of wood, most of the chord section, a small part of the cut surface, if you want to have the same cut, it is more difficult to achieve in solid wood flooring Unless it is a veneer veneer.

Six, choose paint quality

Dripping paint, roller paint floor, commonly known as paint board. Regardless of whether it is a light or matt lacquer floor, the paint film on the surface of the lacquer board should be uniform, full, clean, blistering, and perforated. Among them, the need to put forward is the degree of wear, it is recommended to buy UV light-curable paint, the market dealer referred to as UV paint board, its wear resistance, scalding and other properties are better than other finishing processes. Burning with a cigarette for 20 seconds does not leave a mark.

Mistakes in the selection of solid wood flooring

Misunderstanding 1: Think that the most expensive is the best.

Myth #2: Seek no color difference, and ask for no time.

Misunderstanding 3: Think that solid wood flooring is better than parquet.

special reminder:

1. Do not be confused by the sample in the store.

2. The floor delivered should be optimistic about the lot number on the package.

3. Be sure to invoice.

Solid wood flooring to buy

This is about Centrifugal Fan

 Centrifugal fan is to rely on the input of mechanical energy, increase gas pressure and send gas machine, it is a kind of driven fluid machinery. Centrifugal fans are widely used in ventilation, exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and draft in boilers and industrial furnaces; cooling in air conditioning and domestic appliances and Ventilation; grain drying and selection; wind tunnel source and hovercraft inflatable and propulsion.


Centrifugal fan works with turbine compressor basically the same, are due to the gas flow rate is low, little pressure change, generally do not need to consider the gas volume change, that is, the gas as incompressible fluid treatment.

 

Centrifugal fan can be made of right-handed and left-handed two types. Faced from the motor side: impeller clockwise rotation, known as the right rotary fan; impeller counterclockwise rotation, known as the left rotary fan.

Centrifugal fan from the chassis, spindle, impeller, bearing and motor drive and other components.

Chassis: made of steel sturdy and reliable, can be sub-integral and semi-open, semi-open for easy maintenance.

Impeller: the blade, curved front plate and plate rear plate composition.

Rotor: Static and dynamic balance should be done to ensure smooth rotation, good performance.

Transmission parts: a spindle, bearing boxes, rolling bearings and pulleys (or coupling) composition

centrifugal fan



Centrifugal blowers are widely used in sewage treatment, smelting blast furnace, coal preparation plant, mine flotation, chemical gas, vacuum and other fields, can also be used to transport other special gases.

Features




1. Compact structure: beautiful appearance, good stability, easy installation and maintenance.






2. Smooth operation: Optimized design of the impeller to reduce the axial force to a minimum, and efficient impeller, and static and dynamic balance correction, the machine running smoothly, without any damping device in the case of bearings Amplitude ≤0.04mm.






3. Low noise: blower operation, without any mechanical friction, the use of a reasonable blade-shaped line to the sound to a minimum. Centrifugal blower noise is high-frequency noise, as long as there are obstacles, can be noise, so the fan room almost no noise.






4. Oil-free machinery: Blower bearings with grease lubrication, bearing life of more than three years. Fan does not generate oil and gas during operation. Special requirements fans, with molybdenum disulfide lithium grease lubrication bearings.






5. Impeller: Impeller with a special compound linear, reducing internal leakage and improve the volumetric efficiency.






6 easy to adjust: the inlet valve to regulate flow, the outlet valve to regulate the pressure.






7. Drive: usually using a two-pole asynchronous motor, you can also use four-pole motor drive. Depending on the user grid, different voltage motors can be used.






8. Sealing: In addition to each level of import impeller impeller, the interstage and the housing at both ends with a labyrinth seal to prevent gas leaks.






9. Cooling: exhaust bearing housing has two structures, air-cooled and water-cooled, as the impeller on the level of gas compression, resulting in the exhaust casing temperature is much higher than the intake casing. In the exhaust bearing air-cooled or water-cooled device to extend the bearing life.






10. Bearing temperature control alarm: fan accessories with temperature control box, connected to the bearing through the PT100 resistance, when the bearing temperature exceeds the set temperature, the temperature control box will automatically alarm.






11. Transmission: a coupling drive, belt drive, gearbox drive three. According to different equipment and technology, choose a different transmission
