INTERNATIONAL TRADE PAYMENT SETTLEMENT RISK

With the rapid growth of international trade business is soaring, the bad debts and dead accounts of international accounts receivable are also increasing. The risk of international trade payment settlement is mainly reflected in the lack of effective understanding of foreign customers before trading transactions, and it is unable to obtain sufficient credit for them. After the transaction is completed, there is no timely transaction tracking and settlement of payment problems or business fraud, the other party can disappear with the unpaid bills and debts, causing international receivable accounts to be arrears and no recourse in any form.

 

For customers facing payment risk in international trade and international account disputes, RedStar has business service solutions. From the time when the company signs contracts with the overseas customers and the transaction is tracked to the final payment, RedStar can provide pre-investigation of the other party's background credit, follow-up investigation of business finance, assisting customers to recover the accounts receivable and avoiding the risk of international receivables, including:

 

Account receivable risk

Once the accounts receivable are formed, the accounts receivable customers default, and the case of no one to follow up, due to the stagnation of the company's information and the change of personnel, eventually, lead to overdue, default, or even bad debts.

 

Find missing persons

In many cases, missing persons often leave little clues because of excessive debt or deception, and consciously conceal his position. Only professionals can find them. The cost of finding missing persons depends primarily on the available information about the missing person and the complexity of the search.

 

Investment transaction business risk

What is the difference between static balancing and dynamic balancing?

Dynamic balancing valve is divided into two kinds: flow (flow dynamic control valve) and pressure difference (self-operated pressure difference control valve), which are selected according to actual demand. Dynamic balancing valve is used to solve the branch differential pressure balance problem caused by the frequent operation of temperature control valves at each end. The difference between static and static is that the static balance valve (also known as digital lock balance valve) needs to be locked after one-time debugging by a special intelligent instrument to control the total water volume of the system within a reasonable range, but every change needs to be re-locked by the instrument. The dynamic self-reliance is not so troublesome, depending on the pipe. The pressure change of the adjusted medium in the network can automatically keep a constant flow rate, which is a little cheaper in the static engineering cost.

Principle of dynamic balancing valve: By changing the flow area of the spool of the balancing valve to adapt to the changes before and after the valve, so as to achieve the purpose of flow control.

Dynamic balancing valve can be installed on a water supply pipe or the return pipe. When the working pressure of the system fluid exceeds the allowable working pressure of the radiator, the dynamic balancing valve should be installed on the water supply pipe for safety.

Static balancing valves, also known as balancing valves, manual balancing valves, digital lock balancing valves, double-position regulating valves, are used to solve the problem of branch pressure differential balance in pipeline design.

The working principle of the static balance valve is to change the flow resistance through the valve by changing the clearance (opening) between the valve core and the seat in order to achieve the purpose of regulating the flow. Its object of the action is the resistance of the system, which can distribute the new water according to the proportion calculated by the design. Each branch increases or decreases in proportion at the same time, and still satisfies the requirements. The flow demand of partial load under pre-climate needs plays a role of heat balance.

Static balancing valve can be installed on a water supply pipe or the return pipe. Generally, it should be installed on the return pipe. Especially for high-temperature loop, in order to facilitate debugging, it should be installed on the return pipe. The supply (return) pipe with a balance valve does not need to install the stop valve.

Whether static balancing valve or dynamic balancing valve, they are impedance components, especially dynamic balancing valve, which requires the system to consider the additional head caused by the balancing valve when selecting and distributing pumps.

美国留学身份失效该怎么恢复呢?

I-20表对于所有来美国留学的同学们都是非常重要的,那么,身份失效该怎么办呢,下面就跟求真教育小编一起来看看吧,希望能帮助到大家。

I-20表格是美国移民局签发给所有到美国读书申请F-1签证学生的必备材料,表格上会有一个有效期,学生是可以在此有效期内在美国合法居住和学习的,不过,1-20表格也是会失效的,同学们一定要注意以下两种情况。  

  第一种是当I-20表格到了有效期后,自动失效,另一种就是人为导致的I-20表格失效。若同学们有违反学校的规章制度,例如有抄袭,作弊,学习成绩太低的情况出现,被发现被停学,劝退,开除并导致留学生身份终止,这种情况下I-20签证也会失效。

  那么I-20失效后该如何恢复呢?

  I-20失效后,尽可能快得恢复自己在美国当地的学习合法身份是亟待解决的。若是正常的自动失效,学生已经正常毕业了,就可在毕业后的60天内准备离境事宜。若是人为因素导致的,需要尽快找国际办公室的老师以及寻求专业帮助,尽快恢复自己的身份。

  为了避免此类情况的发生,建议同学们在I-20有效期内尽早开始准备身份重新激活,若在失效之后才发现,在失效后在美国非法逗留不超过5个月的学生,都还可以根据具体情况在美国境内或境外将身份激活的。

不过同学们不要等到出现了滞留在美国当地的情况才开始想办法,因为若I-20失效了,美国的签证也会自动取消。若想再次新入境美国,还是需要重新办理签证的。但若出现过滞留情况,会对今后申请美国各类签证产生影响,所以,大家一定要特别注意。

Bitumen Emulsion Manufacturing Process

Bitumen emulsion is mainly composed of the following five main materials: bitumen, water, emulsifier, acid, and modifier. In order to store stability or to satisfy other special uses, a small amount of additives will be added. Metong is the best bitumen emulsion plant manufacturers. Here we provide the professional bitumen emulsion solution.

The manufacturing process of bitumen emulsion can be divided into the following four processes: bitumen preparation, soap preparation, bitumen emulsion, and emulsion storage.

  1. Bitumen Preparation

Bitumen is the major component of emulsified bitumen, which account for 50% to 65% of the total mass of emulsified bitumen in general. After spraying or mixing the emulsified bitumen, it is going to demulsify. Then the moisture is evaporated. And what remains on the road surface is the bitumen. Therefore, the preparation of bitumen is critical.

Choosing suitable brand and label of bitumen according to the use of emulsified bitumen. The preparation process of bitumen is mainly the process of heating and keeping the bitumen at the appropriate temperature.

During the process of bitumen preparation, the temperature control is very important. If the temperature of bitumen is too low, which will cause the bitumen to be sticky and the flow to be difficult. Thus it will also cause the emulsification to be difficult. If the temperature is too high, on the one hand, it will cause the bitumen aging. On the other hand, the temperature of the emulsified bitumen will be too high, which will affect the stability of the emulsifier and the quality of the emulsified bitumen.

  1. Soap Preparation

According to the different emulsified bitumen, choose suitable  type and dosage of emulsifier and additives to prepare emulsifier aqueous solution (soap liquid).

 

According to the different types of emulsified bitumen equipment and emulsifier, the manufacturing process of emulsifier aqueous solution (soap liquid) is also different. For the automatic continuous emulsified bitumen production equipment, each component of the soap liquid (water, acid, emulsifier, etc.) is automatically completed by the program which is set up by the production equipment itself. As long as the supply of each material is guaranteed, all these processes can be realized; for semi continuous type or intermittent type production equipment, the soap liquid should be manually prepared according to the formula requirements. Some emulsifier water solution needs to add acid to adjust pH value. Some (such as quaternary ammonium salt) do not need. Some solid emulsifiers at room temperature need to be heated and melted before preparing the soap liquid. Because the temperature of soap liquid is generally controlled between 55 and 75 degrees Celsius before entering the emulsification equipment

  1. Bitumen Emulsion

Put the rational preparation of bitumen and soap into the emulsifying machine together. After the mechanical action of pressurization, shearing and grinding, the bitumen will become uniform and fine particles. These particles will disperse evenly in the soap liquid and form bitumen emulsion. The appropriate temperature of emulsified bitumen should be around 85  degrees Celsius.

  1. Emulsion Storage

The emulsified bitumen comes out of the emulsifying machine and enters the storage tank after cooling. Mixing device shall be installed in a storage tank and be used to mix regularly. Because it can help to slow down the segregation of emulsified bitumen.

美国抄袭被发现,后果有多严重?

 抄袭在任何国家都是一种不好的行为,尤其在在学术界一直是遭人唾弃的,今天就跟求真教育小编一起来看看在美国,学术抄袭后果有多严重?

  

  找人代写论文,会被学校开除

  

   近年来,到美国留学的学生越来越多,其中不乏一些基础不好、语言基础不好的留学生,他们会遭遇语言障碍,导致在上课时不发言、写作时不知如何动笔。此时切记没有捷径可走。虽然现在网络发达,信息来源便捷,可以花钱让别人代写作业,但是这并不是你自己的东西,也代表不了一个人的写作风格和水平。

    

  当学习有困难时,并不是没有办法了,光明正大解决问题的办法是有很多的。例如可以找导师寻求帮助。  

  

  写论文应该是留学生获得学位的最后一项任务。学校和导师完全知道和理解非英语国际学生进行英文写作的困境。所以,留学生可以向学校申请,要求增加一两个学期完成论文,绝大多数情况下都可以获得指导教授和学校国际学生处的批准。

  

  不要挑战美国对“学术诚信”的重视

  

  可悲的是,留学生在美国学校抄袭的现象还是比比皆是。“公开教育数据网”(Open Education Database)的一篇文章披露,在他们的问卷调查中,60.8%的大学生承认有不同程度的学术欺骗行为,更让人生气的是,16.5%的答卷人对学生欺骗行为满不在乎。根据问卷调查的结果,只有10%的作弊被抓住。然而,这种侥幸心理使不得。

  

  诚实、不说谎、不剽窃、有错就改,是美国社会必须遵循的道德。一旦背上了不诚实名誉的学生,完成学位就很困难。识破谎言并非难事,一旦公开,终生的学术信用将很难恢复。
