It is the certificate of the conclusion of the transportation contract between the carrier and the shipper; 2. It is the document that the carrier accepts and transports the goods. ; 3. It is the freight settlement certificate and the freight receipt; 4. It is the basis for the carrier to transport the goods in the whole process of the cargo transportation organization; 5. It is the certification document for the clearance of international import and export go

  The Amazon   product quality inspection   report is a test report handled by a third-party testing agency when the product is listed on Amazon. All products on Amazon need a quality inspection report, which is the product quality inspection report. The quality inspection report is According to the requirements of standardization, carry out quality inspection and quality supervision on products and projects, and write a written report reflecting the quality of products and projects after analysis and research. So how to handle the Amazon quality inspection report? The following editor briefly introduces What is a product quality inspection report? Th e re are many names for quality inspection reports. Some are called inspection reports, and some are called quality inspection reports, but they are basically the same, mainly referring to the product quality inspection reports issued to you by the “product inspection agency”. A conformity certification for your product. The regular produ

          As people's requirements for industrial cleaning efficiency become higher and higher,   ultrasonic cleaning equipment  is also used more and more widely. Many companies have purchased ultrasonic cleaning machines. So which cleaning agents are suitable for ultrasonic cleaning machines? Are traditional cleaning products applicable?         First of all, what we know is that most of the products cleaned by ultrasonic cleaning machines are metal workpieces, copper and aluminum plates, optical glass, etc., which are relatively small in size and relatively clean.         Ultrasonic cleaning is essentially immersion heating cleaning. All water-based cleaning agents must be used. Therefore, ultrasonic cleaning uses ultra-high frequency vibration to achieve the cleaning effect. All the environmental protection and safety performance of the cleaning agent itself have higher requirements.         So all in all, the  ultrasonic cleaner equipment  needs to be equipped with water-based

The poor quality of electroplating coating is partly due to poor cleaning quality before plating. Decorative electroplating and functional electroplating have higher requirements on electroplating quality.   Ultrasonic cleaning equipment  should be very popular in electroplating, while precious metal electroplating and special The pre-treatment of electroplating can not leave the ultrasonic cleaning.         The traditional cleaning before electroplating mostly uses multi-stage chemical degreasing and electrolytic degreasing, supplemented by various mechanical aids. Compared with ultrasonic cleaning before electroplating, it has obvious advantages.         1. Simplify the cleaning process before plating         One-time ultrasonic cleaning is often better than multiple chemical and electric degreasing effects. For electroplated parts with complex shapes, chemical and electrolytic oils are difficult to achieve the desired effect, but ultrasonic cleaning can be easily achieved.         2

The indispensable process in machining production is the cleaning of metal parts and materials, because the laser cutting process of different metal materials and different types of oil stains may appear on the surface of the mechanical equipment at the same time, so I want to ensure the correct development of the production process. It is necessary to completely remove the oil stains on the metal parts. The most widely used method is to use   ultrasonic cleaning equipment   with water-based industrial metal cleaning agents to clean.         Because of the different types of oil stains on the surface of the parts, the appropriate cleaning method is selected according to the composition of different oil stains. Commonly used cleaning agents include chemical pickling, chemical alkali cleaning, gasoline kerosene cleaning and water-based metal cleaning agents. The first three cleaning methods exist Defects of varying degrees and narrow application scope, while metal water-based cleaning ag

In our production and processing process, the surface of metal products is often stained with oil.   If there is a lot of oil on the surface of the product, it cannot be used at all. Therefore, we need to clean the oil on the surface of the product before proceeding to the next process. The most basic requirement for cleaning the surface of metal products is to choose a safe, environmentally friendly, efficient, and non-corrosive degreasing powder. This will not only protect the environment, but also benefit the health of employees. Choosing a suitable degreaser powder is very important, which requires us to comprehensively consider various factors, such as process, product material, cleaning method, etc., and select a cost-effective degreaser powder in a targeted manner. Degreasing powder is generally alkaline, only little pollution to the environment. Scrubbing, rinsing, dipping, and ultrasonic cleaning are all can do. The cleaning metal can be aluminum alloy, zinc alloy, magnesium a

The  industrial cleaning agent  industry is a branch of the petrochemical and chemical industries, and an important auxiliary industry serving industrial production and manufacturing. But for many years, the development technology of my country's industrial cleaning agent industry still lags behind foreign countries. Both large-scale cleaning equipment and industrial cleaning solvents are mainly imported from abroad. However, as the Chinese government began to pay more attention to environmental protection and committed to improving air quality, some companies focusing on the production and research and development of environmentally friendly industrial cleaning agents have found development opportunities.         Analysis of the status quo of industry demand         The demand for cleaning agents and cleaning equipment in various industries is still strong, and the following major hot markets have been formed:         1 、 Electronic Information Field         In development zones a

Four advantages of using ultrasonic cleaning machine for electroplating coating cleaning The poor quality of the electroplating coating is partly due to the poor cleaning quality before plating. Both decorative electroplating and functional electroplating have higher requirements for electroplating quality, and ultrasonic wave should be very popular in electroplating. The pre-treatment of precious metal electroplating and special electroplating cannot leave the  ultrasonic cleaning . The traditional cleaning before electroplating mostly uses multi-stage chemical degreasing and electrolytic degreasing, supplemented by various mechanical aids. Compared with ultrasonic cleaning before electroplating, it has obvious advantages. (1) Simplify the cleaning process before plating One-time ultrasonic cleaning is often better than multiple chemical and electric degreasing effects.

Industrial oil cleaning has always been a difficult task for many factory cleaners. Only by choosing an  industrial cleaning agent   that meets their cleaning needs can the effect of high cleanliness be achieved. In order to achieve this goal, it is necessary to have a good understanding of cleaning workpieces, cleaning equipment, cleaning agents, and cleaning methods, so that the cleaning work can be doubled with half the effort.           1. Workpieces to be cleaned Generally, there are aluminum, copper, iron, zinc alloys and other types of workpieces to be cleaned. In the production process, the type of dirt on the surface of the workpiece (oil, wax, dust, etc.) 3. Whether the structure of the workpiece is complex, with seamless gaps and blind holes 4. Whether there is The surface coating is easy to scratch and fall off. 5. Whether it is easy to rust. 6. Whether the workpiece is made of composite materials, such as plastic inlaid on the alloy. 7.

The discharge of industrial waste water is a headache for many small and medium-sized enterprises. With the increasingly strict environmental protection, the discharge of industrial waste water is also subject to more and more stringent restrictions. Many companies that do not have too many environmental protection concepts have to start to face it. Environmental protection issues of wastewater discharge. Recently, I often receive questions from some customers about environmentally friendly  industrial cleaning agents , and I came up to ask if there are environmentally friendly cleaning agents that can be discharged directly? In fact, there is no waste liquid of industrial cleaning agent that can be directly discharged. Even if only pure water is used for cleaning, the oil in the cleaning liquid cannot be directly discharged. National laws stipulate that all industrial waste water is non-dischargeable, especially industrial cleaning waste water, which cannot be discharged directly. If
