Speaking of the TV box, if you have followed it two or three years ago or you are a TV box user, then you should be able to recall how hot the TV box market was, and with the popularity of smart TVs, it may be quite a lot. People will think that the TV box market will gradually shrink, and finally the TV box may gradually disappear. In fact, this may not be the case. After the TV box is standardized, everyone can get more quality content from the TV box. Perhaps everyone Still can't leave the TV box?

Leakage of doors and windows, as a common problem in the quality of construction projects, has always been one of the quality issues affecting the use of construction projects, leading to complaints from owners and high repair rates. The following combination of years of engineering practice experience, and through investigations with material suppliers and door and window processing units, on the basis of careful analysis and study of the quality of doors and windows and leakage problems, the reasons for the leakage of building doors and windows project Analysis and how to effectively prevent:

Once the leakage problem of building doors and windows projects occurs, it is more tedious to carry out repairs. The first reason is that it is not easy to determine the location of water leakage, and the maintenance duration is relatively long. Second, it is not easy to repair once, and often requires multiple repairs, which will have a great impact on the daily life of the owners. Therefore, as a professional technician of the construction industry, we are responsible for summarizing and analyzing the leaks in the doors and windows of construction projects to find out the causes of the leakage problems, and conduct detailed measures from the aspects of design selection, material processing, and finished product installation. To strengthen the detailed quality management during construction, and really prevent and control the leakage problem from the source to ensure the quality of the project.

Causes for Leakage of Doors and Windows 1. Larger windows use larger pieces of single glass. There is no reasonable separation. With additional reinforcement frames, when the air pressure is high, the vibration of doors and windows leads to water in the profile gap, and the leakage of the doors and windows is caused by irrational design.

2. There are air bubbles and cracks in the sealant between the door and window frame and the door window wall. Some windows and doors are opened in winter. The sealant loses its adhesive strength and the seal is not leaking.

3. The on-site window frame is directly fixed on the heat preservation layer, and the water-proof strengthening treatment is partially adopted, resulting in leakage between the insulation layer and the wall of the door and the door after the storm.

4. Cracks in the splicing gaps of door and window frames, bolt holes are not glued, or glue is not dense, resulting in leakage.

5, hinge adjustment is not in place, the pvc rubber strip used is relatively poor flexibility, window sash processing deviation is greater, leading to a larger gap between the door and window frame and the door and window fan, leak tight seal.

6. There is no plastic seal between the door and window profile and the glass, and there is no glue seal between the gaps. Under the action of the wind pressure, the sealing between the profile of the door and window fan and the glass is not strict and leaks.

7. The drain hole is improperly set and part of the drain hole cover is closed under the wind pressure to close the drain hole, leading to flooding inwards.

8. There are empty drums, cracks, and sanding on some window sills, resulting in leaky seals. Some of the floating windows (window decoration effect map) have water in the roof, leakage, and flooding of individual windowsills, resulting in water retention, leakage.

Door and window leakage prevention measures 1. Before the installation of doors and windows, “three performances” witness sampling inspection shall be carried out. After installation, a qualified laboratory shall be commissioned to conduct on-site “water tightness” and “air tightness” inspections.

2. After the doors and windows are installed, a qualified inspection agency shall be commissioned to conduct on-site inspections in accordance with relevant regulations and procedures.

3. Check the size of the reserved wall hole before the door window frame is installed and fixed. The size of the door and window frame hole should be set too large and handled improperly, which will easily cause cracking and seepage. When the deviation is too large and the repair thickness is more than 50mm, the reinforced concrete mold should be used to repair the C20 fine stone concrete. When the repair thickness is less than or equal to 50mm, the waterproof mortar can be added to the steel wire to streak and roughen to repair the gap. In order to enhance the waterproof effect of the perimeter of the door frame, the waterproof mortar is applied to the masonry hole and then the outer frame is fixed. After the fixing, the outer frame and the wall are determined according to the decorative material.

4. The installation of doors and windows should be fixed with galvanized iron sheet. The thickness of galvanized iron sheet should not be less than 1.5mm. The spacing between the fixed points should be 180mm at the corner and not more than 500mm at the edge of the box. It is forbidden to use the long foot expansion bolts to penetrate the profiles to fix the door and window frames. Composite window splicing node should take the method of splicing surface.

5, door and window openings should be clean and dry after spraying foaming agent, foaming agent should be continuous playing, a molding, filling full, overflowing the door and window frame outside the foaming agent should be plugged into the gap before the conjunctiva to prevent the foaming agent outer membrane damaged. The sealing rubber strips of the inlaid glass should be appropriately lengthened by 20 mm according to the circumference, so that they are in a natural state and must not be tightened. The length of the brush strips must be in place.

6. 5mm wide rubber slot should be left outside the door and window frame.

7. The glue surface should be cleaned before it can be applied, and neutral silicone sealant should be used.

8. When the plastic door and window hardware is installed, the metal liner must be installed, and its thickness should not be less than 3mm. When tightening the installation, it must be drilled first and then screwed into the self-tapping screw. It is forbidden to hammer into it directly. The result of the prevention and control is that there are no leaks on the site.

In order to enhance safety, all industries are currently buying gas detectors . However, consumers generally do not know much about the gas detection industry. They do not know how to choose a detector that is suitable for their own situation. The following and gas detector manufacturers can jointly learn about Gas detector can not ignore several features:

1. Stability Stability This is a must. The zero offset and full amplitude offset values ​​for our primary considerations are as small as possible.

2. Convenience and Convenience Now we are all working on the outside. In the premise of stability, convenience is also a factor that must be emphasized. It is lightweight, small in size, easy and comfortable to wear, and easy to maintain.

3. Applicability technicians identify and evaluate hazardous gases on a limited space operation site to determine whether the selected detector's sensor meets uغير مجاز مي باشدe requirements.

4. Reliability The longer the sensor life, the better. In general, the sensor life is at least 2 years, and the flammable gas sensor is 2 to 5 years. The longer the average error time, the better, the accuracy and precision, and the smaller the error value, the better.

5. The protection requires whether the explosion-proof safety grade is applicable to the workplace, whether the product safety is certified, whether there is explosion-proof certification or measurement certificate.

6. Whether the visibility of the display area is large enough, whether the font is clear, whether the alarm sound is large enough, and whether the alarm flash light can be recognized from various angles.

"Tui Yi Travel Shooting" system is on trial operation

Eating, living, traveling, traveling, shopping and entertainment have long been the six elements that seem to cover all of our imaginations for travel. However, as the times become more open and diverse, travel is becoming more and more personalized. People have more and more motives to travel. The meaning of travel needs a more perfect interpretation in the new era.

If you are tired of those stereotyped routines, then come and learn about the "Tour Memories." The travel memories (Jindou Cloud) are becoming the “seventh element of tourism” beyond the traditional concept. It is a pioneer in the integration of humanistic photography and art travel photography. It is composed of a professional “cultural and creative team” and a powerful “new cutting-edge photographer team”. For visitors to tap the most beautiful memories of the journey.

"Desolation of the desert" "Tui Yi travel photography" works

The female writer San Mao said, "The true happiness of travel lies in the process." It is true that every trip, every journey, every excited lookout, every reluctant look back, every time tension and touching, every joy or sadness, is difficult to duplicate. Recalling the journey is just a quiet observer, quietly pressing the shutter to record the purest journey for you. The actions and expressions that convey love, affection, and friendship woven the story of your journey. After many years, everything that you and the most important person in your life have experienced on the road is the most precious personal artwork - you can be so beautiful!

Different cultural adventures, never experienced art journey

"Graduation Trip" "Tui Yi Travel Shooting" Works

The Jindou Cloud Travel B2B platform is the core project of Chunxiao Capital's tourism strategic layout. Its “Tony Travel Film” is followed by a professional photographer team. It uses professional photography technology to provide tourists with unique travel photograph services from a unique perspective. The unique culture of the land of travel allows visitors to integrate into the new realm of people, scenery, culture and art.

In recent years, the tourism industry has experienced rapid growth. In 2012, the domestic travel market was only 300 million yuan. In 2013, the market share has reached 2.8 billion yuan, and it has grown to 6 billion yuan by 2014, and after one year, this figure It quickly reached 15 billion yuan. However, prior to the launch of “Television Travel”, the domestic travel photography was mainly for wedding travel. It is no exaggeration to say that up to now, there are mainly two categories of travel photography industry in China, one of which is wedding travel photography, the other is “humanity travel photography” based on humanistic photography.

"Blissfulness" and "Photography"

Compared with ordinary travel photography, the biggest difference is that the photographers are not satisfied with the basic needs of stopping to take pictures, but are built on the basis of history and cultural expansion to allow travelers to deeply integrate into the local area. Local customs, with humanistic photography as the entry point, through the shooting scene, accommodation, catering, performances, activities, life experience, different ethnic cultural exchanges, for each traveler to customize the most pure journey story. At the same time, it also designed and developed derivative products that meet different consumer groups, such as postcards, puzzles, custom suitcases, and real estate, etc., as value-added services to enhance their derivative value.

For photographers in the “Television Travel”, the entire filming process is the most rigorous process of artistic creation. At present, in the short period of time, the “Tour of Travelers” has a team of about 3,000 photographers. They have extensive experience in portraiture photography, have worked in professional photography media, or have worked with famous brands and famous artists for many years. The most important thing about cooperation is that they, like you, love to travel, yearn for excitement, and nostalgia for years.

The seventh element allows tourists and local agencies to win

There is no doubt that the travel industry has great potential. The "Tour of Travelers" is born on a regular basis and has become a leader in this new trend of tourism. In the past two months, “Tourism Traveling and Shooting” has made full efforts in the four major regions of South China, East China, West China, and North China. The market prospects are unlimited.

Jin Douyun, Deputy General Manager, Yao Yiqiang (left)

Mr. Yang Yaoqiang, the core person in charge of “Tianyi Travel Photography”, said: “Almost all travelers are more or less dissatisfied with the existing forms of travel. They hope that travel agencies provide higher-end services, but the problem is that current traditional travel agencies lack innovation. Ability and thinking can't separate from the traditional six elements of tourism, while "Tienyi Travel Photography" has introduced the concept and service of humanistic travel photography, which makes the travel full of surprises and can add an artistic atmosphere to the travel."

"Culture inheritance" "Tui Yi travel photography" works

According to Yang Yaoqiang's introduction, “Television Traveling” not only brings new elements to tourist travel, but also optimizes existing traditional travel agency products to a certain extent, and solves the problem of product homogeneity that has existed in the industry for a long time. For Geosciences, the commercial value brought by “Recall” is clear: the richer product line and upgraded product experience have greatly improved the competitiveness of Geosciences. At the same time, “Television Traveling” has made every trip of tourists become storable artwork. The higher quality of service will naturally win a better reputation and thus increase the brand awareness of the company.

"Brothers Together" "Tour Photographs"

Still staying in the food, accommodation, travel, travel, shopping, entertainment, travel agencies have been unable to meet the needs of tourists more outspoken, newer, more personalized journey. “Taiyi Travel Photography” pioneered the integration of humanistic travel photography concepts and services with the traditional tourism industry to better help travel agencies provide tourists with more valuable, high-end, innovative, fun and playful services. At this moment, all the tourists are witnessing - the seventh element of tourism: "Tui Yi travel photography" quietly formed.

On June 30th, at the 21st China International Software Expo, Mobike won the “Golden Nomination Award”. This award is the highest rating in the domestic software industry. The Chinese Academy of Engineering Academia Yanagen was the world’s first smart lock developer and vice president of Mobike’s Yang Zhongjie. He praised Mobike’s efforts to create a smart shared bicycle model in the world and promote the development of the global mobile internet of things.

As a top student in the cycling field, Mobai has been highly appreciated by all walks of life.

Behind the highly appreciated is the constant result behind Mobike. Mobike not only opened the first smart bike to move the Internet of Things, but also used data to groom traffic.

Mobike developed the world's first "full Netcom" smart lock and launched the global mobile IoT platform. In May 2017, Mobike launched cooperation with Qualcomm and China Mobile Research Institute to launch China's first LTE Cat M1/NB-1 and E_GPRS (eMTC/NB-IoT/GSM) multi-mode outfield test to achieve the world of shared cycling. A "full Netcom" smart lock. It is reported that up to now, Mobike has been working with telecom operators and equipment manufacturers such as China Mobile, Vodafone, Qualcomm, Ericsson and Huawei to implement the real-world application of NB-IoT IoT technology for the first time in the industry.

At first, Moby was an innovator who did not follow the crowd.

Since the launch of the first bike, Mobike has installed satellite positioning smart locks for each vehicle, generated data in real time, and integrated the Internet of Things, cloud computing, and big data technologies to create the industry’s only artificial intelligence big data platform. "Magic square". In addition, the investment in the early stage is far ahead of other bicycles regardless of whether it is a product or service level.

Mobhai knows precisely how many bicycles a city needs to share a bicycle, and it can even be accurate to the different needs of ports A, B, C, and D in a subway station.

Mobai is still a responsible social enterprise.

The value of Mobike's data can serve the construction of smart cities, and data on bicycles can be used to ease traffic.

It is worth mentioning that Mobi Intelligent Lock constantly optimizes and upgrades positioning technology, and now supports Beidou/GPS/GLONASS three-mode satellite positioning program, and applies DGPS differential positioning technology to improve the positioning accuracy of bicycles to sub-meter level. A person from the Mobike Shandong Regional Company explained to reporters that the reason why a shared bicycle is so hot is that it can even go to the world. Its greatest value lies in the value of data. "The most expensive part of a Mobike bike is its code lock, because it is a data terminal and can learn tens of thousands of people's travel information through the background every day. This important data can ease traffic and ease traffic in a city. Congestion has a vital role to play, and this is precisely the advantage of sharing bicycles that foreign cities value."

Experienced the applauses of Davos, Soft Expo and other representative industries, it is the recognition and encouragement of Mobai. Mobai will continue to uphold the spirit of ingenuity and lead the continuous development of the shared bicycle industry.
