Project Name: Nanjing Grandeur Clean Shed

Project Introduction: Design, Production and Installation of Clean Shed

Undertaking time: 2015.11

The company was established in October 2002. At first, the company mainly engaged in various industrial tapes and label paper materials. It is one of the most influential tape and label material suppliers in Nanjing. In April 2007, with years of intensive cultivation in the field of optoelectronics, the company began to enter the field of die cutting. It mainly provides a full range of die-cutting products such as TAPEFIXING TAPE, LED HOUSING, LAMP HOUSING, REFLECTOR, etc. for the optoelectronic industries such as mobile phones, notebook computers, LCD TVs, and digital cameras.

The company is currently the preferred processor of 3M (China) Co., Ltd. industrial tape and adhesive products. The company has also established a good cooperative relationship with major raw material suppliers such as TORAY, NITTO, TERAOKA, DIC, Korea Sanzhi, UTC, S&K, and German TESA.

With the accumulation and development of the TFT-LCD industry in Nanjing, Nanjing has become an important production base for the global optoelectronics industry, and Nanjing Guanjiaye has become one of the important suppliers in the optoelectronics industry chain in Nanjing.

The company is a national high-tech enterprise, a private technology enterprise in Jiangsu Province, a member unit of Nanjing Flat Panel Display Industry Association, a member unit of Shenzhen Flat Panel Display Industry Association, and a member unit of LCD Branch of China Optics and Optoelectronics Industry Association.

New Year, Nanjing clean studio as a professional manufacturer of us, in just two weeks of work practice in client tracking, trouble due to the decontamination tent Nanjing prices caused people really feel the pressure, why not, please carefully listen to small series Said:
With the impact of raw material price hikes that began in the second half of 2016, after the start of the new year, a series of unpredictable price hikes in the history of raw materials has just begun. According to incomplete statistics purchased by our company, the unit price of the main parts of the Nanjing purification shed, the aluminum profile increased by 35%, the acrylic sheet increased by 40%, and the price of acrylic has also appeared out of stock. Even the manufacturers are frightened by the increase. . The only taste in it can only be directly tasted. The increase in raw materials this time has exceeded expectations, which has brought a heavy burden to the manufacturing industry, which is already in a difficult state of survival, and makes us such small and medium-sized enterprises really worse.
This is reckless. An old customer who ordered Nanjing purification sheds the year before and in the first half of last year will have a new clean shed to purchase after the year. The engineering staff of our company actively and reasonably carried out the price and budget work for this company. For customers with very strict cost control, we have also made a quotation based on the principle of high quality and low price. After the two-day price comparison work is over, we are informed that this time the aluminum profile and acrylic sheet are 3,000 yuan more than last year. As a result, the business staff of our company are really dumbfounded. In fact, in order to maintain our old customers, the cost of raw materials for clean sheds is calculated as lower than the market price as much as possible. The purpose is to stabilize the customers, even if the profit shrinks. The material that the customer sees has been increased according to the previous unit price, which is really not our fault. Therefore, here is an important thing to say three times: the increase in the price of Nanjing purification shed is not the increase in profit, the increase in the price of Nanjing purification shed is not the increase in profit, and the increase in the price of Nanjing purification shed is not the increase in profit. Although we successfully signed the contract in the end, in fact, we couldn’t bear it. We hope that all new and old customers understand Haihan.

Immediately after the previous post about price hikes, as the editor of a Nanjing clean shed manufacturer , I wrote this article with a thunder and a whirlwind. I thought that 2017 would be a good start. As a result, the rising trend of raw material market prices in the past two weeks has been astonishing. In this boiling market environment, how many companies can survive this fatal blow? As the main products of our company, the clean shed , roller shutter air filter , air shower room, transfer window, etc., are nothing more than welding or splicing of metal materials, with personalized control schemes, and intimate on-site installation and commissioning services. There is a place in the market. Nowadays, raw materials are rising by more than 30% , and the selling price is not rising but falling. How can small and medium-sized enterprises depend on their survival?

The following editor will conduct a brief analysis of the factors that affect the market price of Nanjing purification shed, hoping to arouse the understanding and support of all customers, and work through the difficulties together.

1. Rising metal material prices lead to an increase in core costs

Beginning in September 2016, the mode of comprehensive price increases in China’s industrial sector was officially launched. The frantic rise of bulk raw materials such as coal, iron ore, and paper industry has spread to the entire industrial sector. By the end of the year, the price of metal materials has risen by more than 35% compared with the stable period. This makes the processing and manufacturing based on raw materials face Great dilemma

2. The most stringent “supervision control order” was issued, resulting in a substantial increase in freight rates

Also in September last year, the state issued the most stringent “supervision control”, and the transportation costs of our company to all parts of the country soared. Take a 4 -square roller shutter filter sent to Chengdu as an example. The unit price has risen from 700 yuan to 1,200 yuan. The price difference of 500 yuan is really stressful for manufacturers to pay for the bill.

3. Wages are rising, and labor costs are increasing

As the cost of living and housing prices continue to rise, the increase in workers’ wages is an inevitable result. Take an ordinary worker in our company as an example. The monthly salary at the time of entry in 2009 was 900 yuan, and the monthly salary in 2017 was 3,000 yuan. There is no harm if there is no comparison. If you see an amazing increase, the pressure of employers can only experience the pressure by yourself Up.

To sum up, various factors make it extremely difficult for a company like Nanjing Purification Shed, which relies heavily on raw materials. In the coming year, only by taking precautions and having a sense of crisis can we have the courage and determination to overcome the difficulties on the road. Here we encourage with many peer companies.

For the design of automatic roller shutter air filters, customers often come to learn about the relevant knowledge of roller shutter filter selection after the design institute or environmental engineering company has completed the design plan and construction drawings. On-site civil construction or steel frame structure has been completed, even if there are many dissatisfactions, it is impossible to make corrections. In order to avoid the above problems due to the lack of design experience of the roller shutter filter, this article systematically introduces the design preparation work of the roller shutter air filter:

One,           Roller blind filter processing air volume

The processing air volume is one of the most important indicators in the filter design, and we also select the size based on this indicator. The volume of gas that can be purified by a rolling filter device in one hour. The unit is cubic meters per hour (m3/h) or standard cubic meters per hour (Nm3/h) . The reasonable choice of air volume is often determined based on process conditions and experience. Sewage treatment plants, large blowers, and air compressors are equipped with winding filters to protect the back-end equipment. The design institute generally recommends that the air volume of the equipment is *1.5 or 2 to select the roller shutter filter. When designing or selecting a roller shutter filter according to the air volume, it is generally not recommended that the filter be overloaded for a long time under the design air volume. Otherwise, the filter cotton will be easily blocked, the life span will be shortened, the pressure loss will increase, the filtering effect will be reduced, and even the overall The frame is seriously deformed.

two,           Design wind speed of roller blind filter

Filtering speed is an important factor that determines the filtering effect. We usually recommend a design wind speed of 2.5m/s. Under the right wind speed, the filter cotton has the best effect in intercepting particles. Too high a filtering speed will cause excessive pressure loss, flying particles cannot be effectively intercepted, reducing the interception effect, and making the roller blind filter easy to block. The wind speed calculation formula is m3/min.m2=m/min , which is the ratio of the filtered gas flow (m3/min) to the effective filter area (m2) of the roller shutter. For some customers who are limited in space and cannot select according to the recommended wind speed, increasing the filter speed can reduce the filter area required by the filter, so that a smaller filter device can be used to achieve the same processing air volume.

three,           Roll-up filter temperature and humidity

The operating temperature of the roller shutter filter will affect the two configurations. The first is the maximum temperature resistance of the roller shutter filter. The temperature resistance of the ordinary roller shutter filter material does not exceed 80 degrees, and the temperature exceeding 80 degrees requires special production. High temperature resistant filter material; secondly, the material selection of the overall roller shutter filter is affected. If the temperature exceeds a certain temperature, some plastic components such as limit switches, differential pressure switches, etc., require special treatment or purchase of high temperature resistant components.

If the humidity of the rolling curtain type is high, it is recommended to install a dehumidifying and defogging filter at the front end to effectively intercept and drain a large amount of water vapor, so as not to affect the filtering effect of the back end.

four,           Use environment of roller shutter filter

If the roller blind filter is used in some chemical plants and pharmaceutical factories, we will carry out explosion-proof and anti-corrosion treatments according to the special needs of customers. Some gases that are irritating and harmful to the human body are filtered. How to protect personal safety to the utmost extent and replace them more conveniently and quickly is also within our design range.

Products such as Nanjing air shower room are a kind of purification equipment with strong cleanliness. It is a bridge between clean room and non-clean room, and it is also a necessary passage for people from non-clean room to clean room. People will inevitably bring outdoor impurities into the room when using this equipment, thereby affecting the air quality in the clean room. Next we look at how to understand and Nanjing air shower should maintain the freshness of the air in the room, and matters should be noted that prior to use.

  1. Ways to maintain the freshness of the air in the room

1. For the staff, it is necessary to strictly follow the equipment use process when operating the equipment safely. The entrance and exit of the Nanjing wind shower room must be completely enclosed to prevent outdoor air from entering and affecting the operation of the equipment.

2. For the device itself, the wind leaching equipment requires regular cleaning in the room and ventilation, which requires equipment ventilation system has been in a time efficient working condition. At the same time, there are certain restrictions and rules on the number of air changes for the equipment.

3, for a reasonable flow of people and goods, it is important to maintain the freshness of the method of the room air in the air shower. Before the flow of people, whether to clean themselves in accordance with the requirements of use, and whether the logistics is operating normally, these must be strictly determined.

2. Precautions for use

1. Before entering the clean room, the staff need to remove all the items on their bodies that have an adverse effect on the clean room, such as watches, mobile phones, jewelry, etc.

2, air shower after entering the room need to wear professional clothing room, equipped with a dust cap, clean shoes, gloves and dust masks.

3. When leaving the clean room, you must ensure that the power supply of the room is cut off, so as to prevent leakage of electricity.

  You must maintain a careful and serious attitude in every job. This attitude is not only a driving force for strict requirements on your own behavior, but also an effective way to achieve efficient work. The operation of the Nanjing air shower room is also a manifestation of a serious attitude. We need to use this equipment carefully and do our part to maintain the freshness of indoor air.

Nanjing air shower, as the name suggests, is a purification equipment for personnel and goods to be blown and showered. This kind of equipment is commonly used in various production workshops that have strict requirements on air quality. Nanjing air shower equipment is used very frequently and is the core channel for people and goods to enter and exit. Therefore, after a long time, a series of different failures sometimes occur. When the cargo shower room equipment fails, we, as the Nanjing air shower room manufacturer , have compiled a set of corresponding maintenance methods, let us take a look.

    1. The fan of Nanjing air shower room suddenly does not work

    This situation is usually caused by the sudden cut off of the emergency switch of the cargo air shower box. At this time, you should check whether the switch is cut off. If you are sure that the switch has been cut off, then you just need to lightly press the switch with your hand, then turn it to the right, and finally release it.

    2. The fan speed of the Nanjing air shower room is very small

    The low speed of the fan may have a certain relationship with the line connection. We must carefully check whether the rated volt three-phase four-wire line is reversed under the premise of ensuring product quality. If the line source of the air shower is reversed, the fan in the air shower will not work or the wind speed of the air shower will decrease. At this time, it is necessary to cut off the main brake and reconnect the wires in the correct way.

    3. The power indicator of Nanjing air shower room is not connected

    There are generally four switches in the air shower room , and they are all connected to each other. When the power indicator of the air shower room is not on, please check whether the switch is disconnected. The power switch of the outdoor box of the air shower, the control panel of the indoor box of the air shower, and the switches on the outer boxes on both sides of the air shower.

    Fourth, the valve port of the Nanjing air shower room is blocked

    This situation is generally related to cleaning. Only need to disconnect the power supply, regularly use special cleaning tools to effectively clean the equipment, remove the blockage, and maintain the efficient use of the equipment.

    In short, every failure in the Nanjing air shower room has its own reasons, either improper use, incorrect wiring, or too frequent use, some components are aging, and each failure caused by each cause has its own corresponding failure.的处理方法。 Treatment methods. Responding to failures should keep a clear mind and not go the same way, so that things can be handled more efficiently. Of course, if there is a problem with the equipment, you must choose professional maintenance personnel to deal with it. If it still cannot be solved smoothly, please feel free to contact our Nanjing air shower after-sales staff.

We can see many kinds of dust removal filters in the market. I believe everyone has seen the primary effect filter, but many people may not know it very well. The main function of the automatic rolling-type primary effect filter is that we all know that it is Filters the air, but what are the advantages of this equipment? Why can it be widely used? Let’s analyze it for everyone below.

First, the price advantage is the most prominent. It is low in price and low in cost, and in terms of weight, it is not as heavy as other filters. It is very adaptable. It can be used in many areas and its structure is relatively flexible. So, relatively speaking, many industries Will be used.

Second, in terms of materials, the materials of the automatic rolling curtain primary filter include paper, aluminum alloy, stainless steel, etc. There are many kinds of materials, and the filtering materials are also very diverse, including nylon , Metal, non-woven fabrics, etc., different filter materials can be selected according to different needs.

Third, the scope of application is also very wide, especially in HVAC. It is the effect of filtering in accordance with its price is very good, as long as the dust particles larger than 5 μ m can be filtered out through it, for some of the filter particles less demanding industries, it can fully meet the emission standards .

Fourth, the automatic rolling curtain type primary filter can be used as the first filtration process for dust removal and filtration of various manufacturers, providing the most basic service for other refined filters, which not only speeds up the filtration efficiency, but also improves the subsequent filtration. The equipment has a good protective effect, and the filtering effect is better.

The automatic rolling curtain type primary filter can not only be used as the pre-process of filtering and dust removal in ordinary production industries, but also can be used in office places, meeting space places, commercial places, medical places, airport subways and other areas. The scope of application is also expanding year by year. , I believe that in the near future, all walks of life will have its appearance.
