At present, plastic steel doors and windows have gradually become a new favorite of decoration with its excellent performance and beautiful appearance. However, plastic steel doors and windows are still a new type of building materials in China, and most people are still relatively new to it. So, how to distinguish the advantages and disadvantages of plastic steel doors and windows?

First of all, it is necessary to make clear that plastic steel doors and windows, like other building materials, have high, medium and low grades, and are divided into high quality and inferior quality. The quality and grade of the difference between plastic steel doors and windows are mainly divided into the following aspects:

First, we must first understand the UPVC profiles selected for plastic steel doors and windows. UPVC profiles are the decisive factor for the quality and grade of plastic steel doors and windows. Good UPVC profiles should be rationally designed multi-cavity, wall thickness, anti-aging and anti-UV additives in the formula. From the outside, the surface should be smooth and the color is blue and white. .

In particular, we must remind everyone that many people think that the plastic-steel windows are all the same white. In fact, the color of the high-grade UPVC profiles should be white and blue, and the color anti-aging performance is good. It will not age, discolor or deform in ten years. The middle and low-grade profiles are white and yellow. This color has poor sun protection ability. After a few years, it will become yellower until it ages, deforms and cracks. The reason is that the profile formula contains too much calcium. Everyone has been widely used in the past few years, and now it has become unrecognizable in the calcium plastic window. Therefore, we must carefully select the UPVC profiles, and we can ask the manufacturers to compare the profiles of different profiles, which can be seen at a glance.

The second is to look at the hardware used in the doors and windows. The hardware of high-end doors and windows is made of metal, and its internal strength, appearance and usability directly affect the performance of doors and windows. Many medium and low-grade plastic steels are made of plastic hardware, and their quality and longevity have great hidden dangers.

The third is to look at the assembly quality of doors and windows, mainly to see if the appearance is smooth and clean, whether the welding angle is neat, whether the hardware is matched, whether there is steel lining, etc.

The most important point is that it is necessary to check whether the door and window manufacturers have a production license issued by the construction committee. Don't try to be cheap, and use the plastic steel window produced by the street workshop. The quality and reputation are not guaranteed.

Mini Peristaltic Pump

Mini peristaltic pumps are small, compact devices that are used to pump fluids in a variety of applications. Mini peristaltic pumps are self-priming, which means that they can start pumping fluids without the need for manual priming.They work by using a series of rollers that compress a flexible tube, creating a vacuum that draws the fluid into the pump. The rollers or shoes then release, allowing the tube to expand and push the fluid out of the pump. Mini peristaltic pumps are classified based on their flow rate, which is measured in mL/min or L/min. They can range from very low flow rates of a few mL/min to high flow rates of several L/min. They can also be classified based on their tubing size, which can range from very small diameters of a few millimeters to larger diameters of several centimeters. Mini peristaltic pumps can be further classified based on their application, such as in medical devices, laboratory equipment, or industrial processes.Mini peristaltic pumps are versatile devices that can be used in a wide range of applications, making them a popular choice for many industries.
