Experts recruit doors and windows to buy four elements
A good door and window is the first line of defense for home security. How can we choose a door and window that is both beautiful, classic and durable, and of good quality? This is a problem faced by many owners. Here, Muyuan Shangpin will provide you with some windows and doors to buy, I hope to help you.
First, the materials
The main materials for solid wood doors and windows generally include three aspects: wood, glass, hardware, when the owner purchases products, they tend to pay more attention to the thickness of materials and glass, but the requirements for hardware are not very high. The country's requirements for solid wood doors and windows are certain. The wood material used for high-quality solid wood doors and windows, its thickness, strength and oxide film can generally meet the national standards, for example: the normal thickness of wood edge still solid wood door is 40MM, with belly plate thickness 22MM, if there is customer demand thickening Customized, we prioritize customization according to customer needs.
Second, processing
With good materials, the next step is the processing of doors and windows. Since most doors and windows also rely on the manual operation of the installation workers, this requires the operator to have a good sense of product quality. It is important to enhance the proficiency and product awareness of the operator during the production process. High-quality solid wood doors and windows, fine processing, smooth tangent, uniform angle, there should be no obvious gaps in the splicing process, good sealing performance, smooth switch. If the processing is unqualified, there will be problems with the sealing property. Not only will the wind leak and the rain leak, but under the action of strong wind and large external force, the glass will explode and fall off, which will cause loss of property and even injury to the owner.
Third, the price
Because the price of solid wood doors and windows is higher than the price of composite doors, the price of some high-quality wooden doors and windows is at least 50% higher than that of inferior wood doors and windows. Inferior wood doors and windows usually use sandwich fir, and the original veneer is attached, whether it is from tensile strength or yielding. The degree is much lower than the relevant national regulations. These wooden doors and windows have a short life and low compression resistance. Therefore, when the owner purchases the product, he should not be cheap and despise the quality of the home improvement.
Fourth, the credibility
It is also very important to pay attention to the reputation and service quality of the merchants when choosing. How to honor the after-sales promises that the brand manufacturers can give when it comes to the quality problems of the products in life!

Previous: What is the magic way to identify stone? Next: Cabinet design will become the "watershed" of the future of the enterprise
1. Impeller using the theory of ternary flow design, the application of flow analysis technology to predict the performance of the blower, the variable efficiency of up to 82%
2. See the machine using axial intake and diffuser adjustment device, the flow adjustment range of 45% of rated flow to 110%, so that it operates under non-rated conditions also have a higher efficiency
3. The assembled overall structure, the blower body assembled in the gear box gear box, lubricating oil system, motor and gear box compact layout on a common base, the base also serves as a fuel tank
4. Strict dynamic balance of the rotor, small vibration, high reliability, the overall low noise, low moment of inertia, start and stop the unit a short time, it is with the same flow and pressure multi-stage Centrifugal Fan, the energy consumption is small Light weight, small footprint
5 witnessed advanced and reasonable structure, wearing parts, installation, operation and maintenance convenience. The whole machine bearing vibration, temperature, anti-surge control, start the interlock protection, fault alarm, lubrication system oil pressure, oil temperature control, etc. are using programmable logic controller control, the machine running real-time monitoring
