Nowadays, automatic doors have become more and more popular, and there are more and more door industries. How to choose good doors has become a headache for many ordinary people. The following small series gives you a detailed introduction to the method of judging the quality of doors.
First, the color door identification
1, solid wood door: the price is high, the pure solid wood door on the ordinary market is very small. If the solid wood door is not well done, it is very simple to deform. Red pine, Chinese fir, eucalyptus, etc. are attributed to the lower grade wooden door materials, high-grade solid wood has walnut, cherry, Sapele and so on.
2, solid wood composite door: the first is the solid wood to do the skeleton, the exterior is attached to the door made of high-grade veneer, the appearance is generally very beautiful, the price is reasonable. The primary strength is that it does not deform and does not crack.
3, molded door: the construction process of the molded door is simpler, it seems that there is no solid wood door thick and beautiful. This type of door is used primarily in balconies, storage rooms, etc. that are not always open. One problem with molded doors is that the release of harmful gases can cause indoor pollution.
4, the door: 1. Look at the flatness of the door frame, since it is a steel door, it should be relatively hard, 2. Look at the lock, the inside of the set door is used to support the steel outside. The part of the door lock is not supported by wood, the steel can be stable and straight, indicating that the quality is better, 3. Whether the door has glass, adding glass usually increases the weight of the door, and the opening and closing are more handy. 4. The thickness of the door, the door frame portion is mostly 1.0, and the door flower portion is usually 0.8.
Second, the number of the door to buy the door to do good or bad and quality judgment:
1, buy a door: strengths - beautiful appearance, exquisite workmanship, environmental protection. Relatively speaking, the door to buy is more environmentally friendly. Since the mechanized sheets are purchased in batches, they are usually placed for a period of time and then processed, which is beneficial to the evaporation of formaldehyde. Other manufacturers on the right track will pay attention to the environmental protection of the board.
2, do the door: The door made by the decoration workers is cheap, suitable for families with special requirements for the style of the door. The primary information for the door is the large core board. Many home decoration pollution sources are too much use of the large core board, so we must pay attention to the environmental protection function of the board.
3, sound: When choosing a solid wood door, you can look at the thickness of the door, you can also tap the door by hand. If the sound is evenly boring, the door is of good quality.
4. Component: The higher the solid wood share of the ordinary wooden door, the more the door will sink. If it is a pure solid wood door, the appearance of the markings is very irregular. At a glance, the surface of the door is lubricated and beautiful, often not a real solid wood door.
A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe. A blind flange is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.
Although the word flange generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as 'flanges':
There are many different flange standards to be found worldwide. To allow easy functionality and interchangeability, these are designed to have standardised dimensions. Common world standards include ASA/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). In the USA, ANSI stopped publishing B16.5 in 1996, and the standard is ASME B16.5
