Tiangong No. 1 changed the floor and triggered hot discussion

Tiangong No. 1 changed the floor and triggered hot discussion What is the most advanced renovation project? It is to change the floor for Tiangong No.1. Several days have passed since the smooth return of China’s number 10. However, the astronaut’s move to replace the new floor in Tiangong 1 has caused a stir in the floor industry. How does the Tiangong 1 change the floor in space? What are the floors and decoration materials that are exchanged? These floors and materials will one day enter home life? For this reason, we interviewed the relevant floor industry veterans and related research experts.

The replacement of the hard floor in Tiangong 1 can be seen from the video. After the ground personnel checked and confirmed the interior of the Tiangong-1, the Beijing Aerospace Flight Control Center issued an order to the astronaut to carry out the replacement test of the interior decoration materials. The astronauts Nie Haisheng, Zhang Xiaoguang, and Wang Yaping, dressed in blue overalls, successfully removed the soft floor materials originally laid by Tiangong No. 1 and replaced them with hard floors and new limit devices.

Why did Tiangong 1 replace the original soft floor material and replaced it with a hard floor?

According to reports, the Tiangong 1 floor replacement was due to the Shenzhou 9 astronauts returning to the ground and reflecting that walking on the hard floor feels more comfortable and is easier to control posture. On the Tiangong 1 in the original, only one piece of “biking” was a hard floor. So the God 10 astronauts had an additional task of changing the floor. Experts explained that under the weightless environment, the force of the soft floor is difficult to control and it may cause astronauts to feel unbalanced. The hard floor will be more conducive to the astronauts maintaining body stability under weightless conditions, making the astronaut’s space life more convenient and comfortable, and also accumulating experience for future space station astronauts on-orbit maintenance of spacecraft.

It is rumored that the "space floor" from Jiangsu Tiangong 1 replaced the new floor has also attracted the attention of many people in the industry.

Before the media reported that the floor of the replacement of Tiangong 1 should be a new technology from the industry - micro-carbonization process. For a time, the micro-carbonization process solid wood flooring has become the focus of industry discussions, frequently appear in major media.

According to reports, this technology was pioneered by a floor company in Suzhou. It used microwave and infrared technologies to dry and anaerobicly process the floor, and in the absence of oxygen, it was carbonized at a high temperature of 470 degrees Celsius. The inherent characteristics of wood, while the stability far beyond the ordinary carbonized floor, can be suitable for all kinds of complex environments.

In the face of many speculations, the company's Suzhou flooring company issued a clarification announcement saying that due to the “sale network covers most of the country, different regions have different consumption habits, and the floor registration for each region's consumption is not perfect”. Confirm whether the floor of Tiangong No. 1 is produced by the company. Some experts pointed out that the floor is a very real people's livelihood consumer industry, not a high-tech industry, excessive use of "space science and technology" speculation, instead of affecting the quality of the improvement of home life, the nature of the industry to serve the people's livelihood.

Expert analysis of micro-carbonization is not "high-end technology"

Dr. Wu Bi, secretary general of the Jiangsu Timber Industry Association, said in an interview that the environment in space is extremely harsh compared to the earth, and therefore the requirements for flooring are more stringent. Compared to the high requirements for the color and texture of wood on civil floors, space floors pay more attention to their practicality and stability, and ordinary floors cannot function as space users. Micro-carbonization is a good technology to improve the floor carbonization, not only can retain the inherent characteristics of wood, while its stability far beyond the ordinary carbonized floor. However, micro-carbonization technology is not as high-end mystery as the public thinks. Many floors in the industry are involved in this technology. However, due to the relatively high technical threshold and relatively high cost, they are not widely used in civil floor. After visiting the Nanjing flooring market, the reporter learned that many well-known flooring brands have maintained their interest in the new technology used in the space floor, but there are not many floor companies that are scrambling for the concept of "space floor." The person in charge of the floor of the World Friends told reporters that they had cooperated with the Wood Research Center of Nanjing Forestry University several years ago, and they have conducted in-depth research on high-temperature carbonization technology.

The development and breakthrough of aerospace technology can often lead to the upgrading of civilian technology and drive the leap of material technology. Although we don't know how to change the floor in space, what are the floors and decoration materials that are replaced, but "space floor" is an approval of the domestic flooring industry technology. As netizens said, "Space decoration has also entered the era of localization." Now.

A stainless steel pin metal pin is a device used for fastening objects or material together, and can have three sorts of body: a shaft of a rigid inflexible material meant to be inserted in a slot, groove, or hole (as with pivots, hinges, and jigs); a shaft connected to a head and ending in a sharp tip meant to pierce one or more pieces of soft materials like cloth or paper (the straight or push pin); a single strip of a rigid but flexible material (e.g. a wire) whose length has been folded into parallel prongs in such fashion that the middle length of each curves towards the other so that, when anything is inserted between them, they act as a clamp (e.g. the bobby pin), or two strips of a rigid material bound together by a spring at one end so that, when the spring held open, one can insert some material between the prongs at the other end that, the spring allowed to close, then clamp the inserted material. According to their function, pins can be made of metals (e.g. steel, copper, or brass), wood, or plastic.
