The principle of epoxy resin hardening reaction is not perfect at present. According to the different hardeners used, it is generally believed that epoxy resin can be thermosetting products through four ways of reaction.

(1) Open-ring connection between epoxy groups;

(2) The epoxy group reacts with the hardener with the active hydrogen functional group and crosslinks.

(3) The epoxy group is crosslinked by the reaction of aromatic or fatty hydroxyl groups in the hardener.

(4) Crosslinking of epoxy group or hydroxyl group with group of hardener

Different kinds of hardeners play different roles in the hardening process. Some hardeners, such as amines, alcohols and phenols, which have single reaction groups, do not participate in the hardening process and only play a catalytic role. The hardener participates in the reaction between macromolecules during the hardening process and forms part of the hardening resin, such as polyamines, polyols, polyanhydrides and other compounds containing multiple reaction groups.

As a professional epoxy hardener manufacturer, Jiaxing Nanyang Wanshixing Chemical Co. Ltd covers an area of 4 acres with more than 60 employees. We have four advanced production lines and our annual production capacity is 30000 tons, is the largest manufacturer of MTHPA products in China.

The wardrobe is the basic furniture now, and the large capacity of the large wardrobe is also very popular. Although it is easy to use, the daily maintenance of the wardrobe needs more efforts than that of the small one, so learn how to maintain the wardrobe with oppein .

1. Wax regularly

If you want to keep the luster of the wardrobe, regular waxing is necessary, but you should pay attention not to excessive waxing; for the scratches and dents on the surface of the wardrobe, etc. You can use a cotton ball or a paintbrush to apply similar shoe polish to the corresponding position of the wardrobe. If there is water stain, use clean absorbent paper to spread it on the water stain and press it with a heated iron, or use salad oil and toothpaste to smear it, then wipe the furniture clean, and then wax it.

2. Dust prevention

Always keep the cabinet door clean, and there shall be no sundries and dust in the track. When cleaning, the cabinet body and door can be wiped with a semi wet rag. Do not use corrosive detergent. The dust of the track can be cleaned with a vacuum cleaner or a small brush, and the metal parts such as the cabinet frame and the pull rod can be wiped with a dry cloth.

3. Avoid direct sunlight

Although the autumn sun is not as strong as summer sun, if the wood is too dry due to long-term sun exposure and the originally dry climate, cracks and local discoloration will occur easily, which will seriously affect the appearance of the wardrobe.

4. Pay attention to dampproof

(1) a moisture absorber can be placed in the wardrobe, which is generally sold in supermarkets;

• put bamboo charcoal or lime into a container (do not cover it) and put it in the corner of the wardrobe;

(3) tea moisture absorption method: wrap the tea (you can buy some cheap dry tea) with rice paper or newspaper, and put it in every corner of the wardrobe, which can absorb moisture and remove odor, without any side effects on the health. Then, if you want to make clothes fragrant, you can buy some solid aromatics and put them in the wardrobe. (dry tea should be used to absorb moisture and remove flavor before putting aromatics)

5. Pest control.

(1) vacuum treatment: regularly ventilate and clean the wardrobe, which can effectively prevent insects. It can also be cleaned with a vacuum cleaner, which can remove eggs and larvae more effectively.

• clothing cleaning: all clothing should be carefully cleaned and dried before being put into the cabinet. Even chemical fiber and cotton fabrics that are not easy to grow insects should be cleaned before they are stored together with wool products.

(4)thoroughly clean with a brush: if you don't want to clean the closet, you can use the method of sun exposure to repel insects, put the closet in the sun for several hours, and brush the closet once with a brush can effectively remove the eggs.

可以说美国是艺术留学大国，每年都会有很大部分同学前来求学深造，但是在申请的同时也会有一些误区。今天求真教育小编给大家介绍一下美国艺术学校留学需要注意哪些误区，希望对你有帮助。

　　艺术生赴美国留学误区一：

　　无法确定自我定位。与国内的专业设置不同，国外的艺术专业分类丰富而全面。单就美术设计而言，就分为平面设计、服装设计、建筑设计、工业设计、广告设计等。而平面设计下又包含了很多小的分类，例如包装设计、插画设计、海报设计、标志设计、文字设计等。一般学生选择了专业，也几乎等于选择了个人未来的方向。

　　所以留学之前，学生一定要好好了解各个专业，明确自己的兴趣，确定自己的定位。千万不要临时抱佛脚，匆忙决定自己未来的走向。

　　艺术生赴美国留学误区二：

　　不能正确认识院校。美国艺术类留学申请分为两类，申请美国综合性大学的艺术学院和美国艺术院校。大家择校的时候会避免不了参考院校排名。

　　可是事实上，非常多不错的艺术院校并不参与综合排名。像平面设计专业，很多人只知道耶鲁大学，但事实上，美国罗德岛设计学院与其并列第一。

　　艺术生赴美国留学误区三：

作品集越炫酷越好。艺术作品集是几乎国外所有艺术专业的核心考察要素之一，其重要性不言而喻。作品集不在于多么炫酷，而是需要简单直接地表达你的内容。

　　而且每所院校都有自己的艺术风格，每年都有大量学生把握不住学校作品要求风格而错失进入名校的机会。所以应该多关注相应的作品集，把握学校风格，提前做好准备。

What is diatom mud? A lot of people know little about it when it comes to the public's attention, but with the excellent performance of diatom mud known by people, it has gradually become a black horse in the household paint industry. But "gold can't be pure and man can't be perfect". Diatom mud has its advantages and disadvantages. Oppein home will discuss with you the advantages and disadvantages of diatom mud.

Advantages of diatom mud:

1. The most obvious advantage of diatom mud is that it can absorb harmful substances and purify the air, which is its functionality. Because of its pore structure, it can absorb harmful substances in the air and decompose them into carbon dioxide and water, so as to improve the indoor air quality and ensure our health.

2. The decoration is obvious. The diatom mud material is rich in color with natural inorganic pigments, and the texture pattern is made of different props and processes, with strong plasticity.

3. The environmental protection performance is superior. Because it does not contain formaldehyde, benzene and other harmful substances, it can effectively solve the indoor pollution problem that currently plagues the home.

4. It is helpful for sleep, because diatom mud can release negative oxygen ions to purify air and regulate human microcirculation. When the room is wet, it can absorb water molecules, regulate the humidity, make the residents feel comfortable living environment, and increase the residents' sleep time.

5. Sound insulation and eye protection. Diatom mud can effectively absorb noise and reduce decibel. The sound insulation effect is twice that of stone slab. At the same time, the strong light absorption rate can make the eyes feel comfortable and soft, and avoid vision loss.

Disadvantages of diatom mud:

1. The price of single coating is relatively high. Due to the problems of raw materials, technology and construction cost of diatom mud, the price of single coating is relatively high. Although the price is more friendly to the people with the improvement of diatom mud technology, the price is still not dominant compared with the low-end products such as traditional paint latex paint and wallpaper. However, in the long run, the cost performance of diatom mud is higher than that of medium and low-end products

2. The construction requirements are high. Unlike latex paint and wallpaper, diatom mud has high requirements for construction. It needs professional and systematic training and practical painting experience of the master to complete. Therefore, the craftsmanship of the master varies in the market, which requires consumers to distinguish

With the rapid development of economy and the rapid development of information industry, improving production methods, improving operating power, reducing operating costs and improving service quality have become the top priority of all enterprises and institutions. Fixed property management has the characteristics of wide distribution, large quantity and frequent adjustment. In the current form of management, information distortion and lag caused by human factors in the process of information transmission of property changes lead to the fact that accounting can not be synchronized., and can not optimize the allocation of equipment in time, resulting that a lot of high-value property is put on hold and wasted and the authenticity of financial reports was seriously affected. Currently, there are many rfid cards for sale in the market. This article may help you know more about RFID cards.

As a bridge between fixed property and information system, RFID cards technology can integrate daily property management activities and property management system, and then achieve real-time synchronization of information and system information. Therefore, it is possible to set up a set of financial management system based on the skills of RFID card to complete the active management.

RFID card property management system uses radio frequency skills (RFID cards) to equip each fixed property with an electronic tag with only ID number in the world, and uses a hand-held reader for inventory of property. It can quickly read the electronic tag information on the equipment and the read label information is sent to the background server through the built-in communication method and processed by the wireless communication module. Fixed reader is used for access control. The circularly polarized antenna is selected to ensure multi-view tag identification. Then, it finishes all-round and accurate supervision of fixed property and things from purchase, acquisition, handling, inventory, cleaning up to scrap, and so on. Combined with the financial classification calculation and other statements, the real closure of "accounts, cards, things" is consistent.

Because the electronic tag of RFID card has the characteristics of large storage capacity, fast transmission speed, no counterfeiting, concurrent identification and so on, it can record the real-time information of property in the tag reliably and reliably through the support of the database of the financial management channel, and then supervise the real-time financial management, which improves the operation power and reduces the cost and expenditure. Clear operation interface and accurate and timely data processing make the system be a modern operation form, which provides a more reliable basis for enterprise financial evaluation and decision-making plan, and avoids the risk that may be formed in the process of fixed property management.

Property management includes the operation of adding, allocating, shelving, scrapping, repairing and inventory of property. It includes the whole process of equipment from leaving factory, putting into use to scrapping. When the equipment leaves the factory, it is equipped with electronic tags, which write the information of the property. Every time when the property is handled, the reader will read the electronic tags on the property and send the information to the server for processing, and then finish the tracking of the property.

1) Additional operation of property: Fill in the relevant information (place title, property bar code, type, title) of the equipment to be handled in the card issuing procedure, and save the record in the database. Attach (or hang) an electronic tag with property information according to the rules.

2) Property allocation operation: Prepare the property to be allocated, and open the door that controls the stroke switch, and the reader is reading the label at the moment. Take out the property with the electronic tag and walk out of the door. Investigate the quantity of the property displayed on the reader and the LED display screen. It is acknowledged that the electronic tag on the device is read. Close the door, and now the property has been transferred from the base station. Take the property to the destination where it needs to be allocated, open the door, bring the property to the base station, and acknowledge that the electronic tag on the property is read correctly. Close the door and finish the transfer of property.

3) Property repair operation: Prepare the equipment which is now in trouble, open the door that controls the stroke switch, and keep the reader in the condition of reading the label. Take out the device which has problems, investigate the display of digital tube on the reader and acknowledge that the label is read correctly. Close the door of the base station, and the faulty equipment is transferred from the base station. Take the equipment to the warehouse repair area, press the reader control button (the indicator light on the button is on at the moment), acknowledge that the label information on all the equipment is correctly read to press the reader control button again (the indicator light on the button is off), and the equipment is in repair condition at the moment.

4) Property scrap operation: Prepare scrap equipment, open the door of the control stroke switch, and make the reader be in the condition of reading labels. Take out the waste equipment and acknowledge that the label is read correctly. Close the door of the base station and remove the equipment from the base station. Take the equipment to the waste area of the warehouse, press the control button of the waste area reader, and acknowledge that the label information on the equipment is read correctly. Press the reader control button again, that is to say, the device will be discarded.

5) Property inventory operation: press the handset "I/O" switch to turn on. On the top of the interface, we click the opening connectivity windows, click connected GPRS, and start the inventory program.

6) The whole system has the characteristics of long-distance rapid identification, high reliability, high confidentiality, easy operation and easy expansion.

7) Establish safe and reliable property files, strengthen property supervision through high and new skills, allocate resources reasonably, reduce resource waste and avoid property loss.

8) Give full consideration to the actual situation of the company, discuss the problem from the perspective of professional skills, and deal with the problem of disorder and poor real-time property management. Provide an advanced, reliable and applicable digital channel for active identification and intelligent management of incoming and outgoing property, so that the company can make qualitative progress in real-time and dynamic management of internal property.

9) Make full use of the RFID card's function of active collection and communication, wireless long-distance transmission, and complete the real-time co-operation of property change information and system information, and complete the useful real-time monitoring and recording of operation process by the background system, so that managers can timely understand the allocation and application of property in the office.

10) All property data are input at one time, and the system actively distinguishes property status according to data collected by RFID card reader in different areas.

Startrend is a professional RFID card manufacturer. If you are interested in our products or have any other question, please contact us.

RFID card is mainly made by non-contact IC card identification technology. While making RFID card, smart card manufacturers generally need to own high requirements. They need not only certain technical support, but also strong card-making equipment to ensure that there are no errors in the process of making RFID card.

RFID card is divided into low frequency card and high frequency card. The industry of low frequency RFID technology under 13.56MHz has accumulated more than 10 years of mature experience. At present, the industry is most concerned about the technology of RFID in the middle and high frequency band. In the aspect of high frequency, the technology of domestic manufacturers is gradually mature, and they are actively promoting the application of various systems. At present, the demand of domestic RFID cards is very large!

RFID Card Application Market

As a more sophisticated product in smart cards, RFID cards are mainly used in traffic management, security system, attendance management, membership system management, financial system, and the most common is our own identity cards. With the peak demand for RFID in the second generation ID card project in China recede, access control, transportation and IT asset tracking systems have become the strongest growth market of domestic RFID. The application of RFID in industrial automation industry and pharmaceutical industry will be slowed down, which will lead to the re-shuffling of the RFID industry, and more compatibility and mergers will appear in the future RFID market.

　　学生自述(brersonal Statement)一般需要学生自行撰写。可以做一下自我介绍、兴趣爱好介绍、获奖或者课外活动介绍等。有些学校也会有自己设计的问卷调查表格，或者命题小作文让学生填写。这主要是让学校对学生有一个初步的认识。

　　五：学校面试

　　美国高中申请基本都需要面试。面试一般分为现场面试、电话面试以及视频面试。现场面试一般需要1小时左右;电话和视频面试一般需要20-30分钟；根据学生面试情况决定面试时间长度，学校会通过面试来评估学生的综合能力。

Let the Word of God must become the essential foundation in our life as living

You are more than your profession of services to this world

There is the greater gift that’s sweeter of life in living and it must come out of the profession you hold on earth

Tell the World!

Psalm 145:4-6 (NIV); “One generation commends your works to another… They tell of the power of your awesome works—and I will proclaim your great deeds.”

Tell the World!

It’s Only The Word of God that Saves and Deliver Lives from destructive paths of life in living

Matthew 28:18: And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.

Visual displays in simulation training to provide unique training benefits and can be controlled by the visual display system.

Visual Display in Simulators

The visual display system's goal is to present a computer-generated image of the outer-world scene as the simulated vehicle controller would see at any given time. In simulation design, the LED display screen can be controlled by the visual display system.

Unique Training Benefits

A Recognized Simulating Solution
With more than 25 year's experience in LED simulator screen system, Viewpointec's dome solutions are tried and tested. The LED simulator system presents a low-risk solution that does not require further development. Furthermore, Viewpointec engineers and technicians have designed the screen for quick and easy installation. Magnetic locks can be realigned quickly and easily.

Reliability for Lower Labor Costs
One of the most prominent benefits of the Viewpointec LED screen is high reliability and long service life, with many actual device-hours of testing for LEDs establishing a median lifetime well in excess of 50,000 hours. The longer lifetime of LEDs equated to long real-life training experiences, such as the long travel on plane and exhausting fight in the jungle. It also means a lower cost of ownership by avoiding the material and labor costs related to regular scene changes.
