First, what kind of plate is the best wardrobe
Which type of board is best for wardrobes? Is it good to use a density board? Also known as fiber board, it is a man-made board made of wood fiber or other plant fiber as raw material, urea-formaldehyde resin or other suitable adhesive. According to their different density, divided into high-density board, medium-density board, low-density board. MDF is easy to re-process due to its soft and impact-resistant properties, but due to the fact that the national standard for high-density boards is several times lower than international standards, the quality of use of MDF in China is yet to be improved.
2 What kind of plate is the best wardrobe - PlywoodThe line is commonly known as the fine core board, which is made of three or more layers of 1mm thick veneer or sheet glue. This is the most commonly used material in hand-made furniture. Plywood is generally divided into three kinds of plates, 5 PCT board, 9 PCT board, 12 PCT board, 15 PCT board and 18 PCT board of six kinds of specifications (1 PCT refers to 1mm).
3 What kind of plate is the best wardrobe - decorative panelThe panel is a precision veneer of a solid wood board cut to a thickness of about 0.2 mm, a plywood as a base material, and a decorative sheet having a single-sided decorative effect produced by an adhesive process. It is a special way of plywood, with a thickness of 3mm. Decorative panels are currently an advanced decoration material that is different from the oil mixing practice. The plate is the main component of the wardrobe, and its quality directly determines the quality of the product. The wardrobe plate in the market mainly uses artificial boards, and the use of solid wood is rare. The artificial board is divided into plywood, particle board, and fiber board. Among them, fiberboard has high density, medium density and low density.
4 What kind of plate is the best wardrobe?Called Blockboard. It is composed of two pieces of veneer that are spliced ​​together. The price of the big core board is lower than that of the fine core board, and its vertical direction (differentiated by the core material) has poor bending pressure strength, but the transverse bending strength is high.
Fireproof board is made of siliceous or calcareous material as the main raw material, mixed with a certain proportion of fiber materials, lightweight aggregates, adhesives and chemical additives, and decorated with autoclave technology. It is a new type of material that is currently being used more and more. Its use is not only due to fire protection. The construction of the fire board requires a relatively high requirement for glue sticking, and the fire board with better quality is also more expensive than the decorative panel. Fire board thickness is generally 0.8mm, 1mm and 1.2mm.
6 What kind of plate is the best wardrobe - wood shavingsParticleboard is actually what we call particle board. It is the cutting of wood and other raw materials into pieces of a certain size. After a series of drying, adhesive treatment, hardening agent treatment, waterproof agent establishment and other processes, it is suppressed at a certain temperature. Into a plate, this plate is more reassuring in terms of environmental protection, the amount of plastic used in the production process is quite small, most of the plate wardrobe products on the market today are using such materials, so do the wardrobe which What kind of sheet is best? The use of particle board plate is good!
7 What kind of plate is the best wardrobe?The toothed plate is a kind of splicing material made of a number of horizontal and vertical wooden sticks made of adhesive and cold pressed, which is what we call the integrated target material. This kind of plate solid wood plate is more adhesive in processing. Crafts, which solid wood plate and toothed plate do wardrobe Which kind of plate is best? In the processing of toothed plates, instead of using urea-formaldehyde rubber, white latex is used. Therefore, environmental protection allows us to rest assured that when choosing a toothed plate wardrobe, we should pay attention to buying from regular manufacturers.
8 What is the best wardrobe plate - solid wood plateThe solid wood panels are made of complete wood. The materials are taken from natural solid wood. There are no concerns about pollution and safety. However, we know that furniture made of solid wood materials is more expensive. In the closet, solid wood wardrobes are similar. It is also expensive, in which the requirements for production and construction are high, and the production cost is correspondingly higher. Therefore, what kind of plate is best for wardrobes? If you do not require branded wardrobe products, customizing solid wood closets in the surrounding areas of the city is a more reasonable choice.
Second, what kind of plate to do the best wardrobe - attention
The best question about which type of plate is made of a wardrobe is already explained in the above content. Next, let's find out what problems we should pay attention to when selecting a plate wardrobe plate material. 1, plate wardrobe surface First of all, the surface of the plate wardrobe is very important, some wardrobe surfaces look very good, with a nail and a scratch will appear obvious scratches, such a wardrobe product can not be determined; 2, plate wardrobe edge Secondly, the edge of the wardrobe is also very important, manufacturers use precision instruments to cut the plate, the plate is not collapsed around, after the edge of the surrounding air can be placed into the wardrobe to ensure the service life of the wardrobe! Third, the most environmentally friendly sheet
What kind of plate is the best wardrobe? Of course, we must choose the most environmentally friendly plate, as follows:
1, solid wood board
The wood panels are made of solid wood and the materials are taken from natural trees. There is no concern about environmental pollution, but the price is relatively high, and the requirements for production and construction are high.
2, tooth plate
By multiple pieces of wood longitudinal and horizontal adhesives and cold pressure splicing made, that is, integrated board. Compared with the process of solid wood board, there is a more adhesive process. In the process of machining the teeth, the urea-formaldehyde glue is not used, but the white latex is used. Therefore, the environmental protection can be assured.

A ball check valve is a check valve in which the closing member, the movable part to block the flow, is a spherical ball. In some ball check Valves, the ball is spring-loaded to help keep it shut. For those designs without a spring, reverse flow is required to move the ball toward the seat and create a seal. The interior surface of the main seats of ball check valves are more or less conically-tapered to guide the ball into the seat and form a positive seal when stopping reverse flow.
Ball check valves are often very small, simple, and cheap. They are commonly used in liquid or gel minipump dispenser spigots, spray devices, some rubber bulbs for pumping air, etc., manual air pumps and some other pumps, and refillable dispensing syringes. Although the balls are most often made of metal, they can be made of other materials, or in some specialized cases out of artificial ruby. High pressure HPLC pumps and similar applications commonly use small inlet and outlet ball check valves with both balls and seats made of artificial ruby, for both hardness and chemical resistance. After prolonged use, such check valves can eventually wear out or the seat can develop a crack, requiring replacement. Therefore, such valves are made to be replaceable, sometimes placed in a small plastic body tightly-fitted inside a metal fitting which can withstand high pressure and which is screwed into the pump head.
There are similar check valves where the disc is not a ball, but some other shape, such as a poppet energized by a spring. Ball check valves should not be confused with Ball Valves, which is a different type of valve in which a ball acts as a controllable rotor to stop or direct flow.
A diaphragm check valve uses a flexing rubber diaphragm positioned to create a normally-closed valve. Pressure on the upstream side must be greater than the pressure on the downstream side by a certain amount, known as the pressure differential, for the check valve to open allowing flow. Once positive pressure stops, the diaphragm automatically flexes back to its original closed position.
A swing check valve or tilting disc check valve is check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow. The seat opening cross-section may be perpendicular to the centerline between the two ports or at an angle. Although swing check valves can come in various sizes, large check valves are often swing check valves. The flapper valve in a flush-toilet mechanism is an example of this type of valve. Tank pressure holding it closed is overcome by manual lift of the flapper. It then remains open until the tank Drains and the flapper falls due to gravity. Another variation of this mechanism is the clapper valve, used in applications such firefighting and fire life safety systems. A hinged gate only remains open in the inflowing direction. The clapper valve often also has a spring that keeps the gate shut when there is no forward pressure. Another example is the backwater valve (for sanitary drainage system) that protects against flooding caused by return flow of sewage waters. Such risk occurs most often in sanitary drainage systems connected to combined sewerage systems and in rainwater drainage systems. It may be caused by intense rainfall, thaw or flood.
A stop-check valve is a check valve with override control to stop flow regardless of flow direction or pressure. In addition to closing in response to backflow or insufficient forward pressure (normal check-valve behavior), it can also be deliberately shut by an external mechanism, thereby preventing any flow regardless of forward pressure.
A lift-check valve is a check valve in which the disc, sometimes called a lift, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. A guide keeps motion of the disc on a vertical line, so the valve can later reseat properly. When the pressure is no longer higher, gravity or higher downstream pressure will cause the disc to lower onto its seat, shutting the valve to stop reverse flow.
An in-line check valve is a check valve similar to the lift check valve. However, this valve generally has a spring that will 'lift' when there is pressure on the upstream side of the valve. The pressure needed on the upstream side of the valve to overcome the spring tension is called the 'cracking pressure'. When the pressure going through the valve goes below the cracking pressure, the spring will close the valve to prevent back-flow in the process.
A duckbill valve is a check valve in which flow proceeds through a soft tube that protrudes into the downstream side. Back-pressure collapses this tube, cutting off flow.
A pneumatic non-return valve.
Multiple check valves can be connected in series. For example, a double check valve is often used as a backflow prevention device to keep potentially contaminated water from siphoning back into municipal water supply lines. There are also double ball check valves in which there are two ball/seat combinations sequentially in the same body to ensure positive leak-tight shutoff when blocking reverse flow; and piston check valves, wafer check valves, and ball-and-cone check valves.
