The appraisal sites are * * * and Xinlu * * * and Room A101Block A of International No.3699.. The evaluation time is 20 14-5- 10. Evaluation brand Gumeier evaluation product, green nano super antibacterial tube, product specification is 25*4.2, reference price is 15 yuan.
First, the first impression of the appearance of Gu Meier green nano super antibacterial tube
Green symbolizes life, balance, peace and vitality. The outer wall of Gu Meier nano super antibacterial tube is bright and eye-catching, and the inner wall is milky white. By touching the pipe wall, you can feel that the outer wall, inner wall and cross section are smooth, which meets the criteria for judging high-quality pipes. In addition, the wall thickness of other general water pipes is only 2.8mm, while this pipe wall thickness is 4.2mm, which is more durable.
Second, the details of Gu Meier green nano super bacteriostatic tube.
1, double-layer structure -—PPR layer+nano antibacterial layer
Let's look at the cross section of the water pipe. We can see that Gumeier nano super antibacterial tube has two-layer structure, the outer layer is modified nano composite PP-R material, which is the green part we see, and the inner layer is the nano antibacterial layer extruded by advanced equipment, which is the white part we see. Nano-antibacterial pipe is a functional layer with high efficiency and broad spectrum antibacterial added to the inner wall of PP-R pipe, which plays an antibacterial role and ensures the cleanliness and hygiene of the pipe.
2. Product information and anti-counterfeiting labels
The outer wall of Gu Meier Nano Super Antibacterial Tube is printed with information such as manufacturer, full name of product, production batch, etc. In black font, each tube and fittings of Gumeier are affixed with anti-counterfeiting password, which is convenient for consumers to make inquiry calls when purchasing and distinguish authenticity.
Three. Evaluation Details of Green Nano Super Bacteriostatic Tube in Gu Meier
1, dimension measurement
There are strict standards for the size of water pipes, and there can be no difference. The standard outer diameter of Gu Meier nano-super antibacterial tube is 25mm, and the thickness of tube wall is 4.2mm The appraiser verified with tape measure that all the 10 tubes meet the requirements, so it can be seen that the specification standardization from the big factory is guaranteed.
2. Water pipe flexibility test
Before bending
Yield and compromise
The on-site assessor bends the water pipe by hand, and after releasing his hand, the water pipe slowly changes back to its original appearance. It is not difficult to see that the Gu Meier nano super antibacterial tube is very flexible, suitable for coil laying and very resistant to bending.
3, hot melt test
The water pipes of PPR are all connected by a fuser, so the stability of water pipes after heating is very important.
The evaluator first finds the special fixer for PPR water pipes, plugs in the power supply, connects the water pipes and fittings at both ends respectively, and presses the heating button. During the heating process, the water pipe and fittings are gradually softened and bonded together, and there is no peculiar smell and white smoke in the process, indicating that the materials used in the product are environmentally friendly and healthy. After hot melting, the water pipe and fittings are firmly connected and inseparable.
The appraisers cut the hot-melt part with scissors, and everyone can clearly see that the hot-melt part has no discoloration, no pores and no gaps, and the hot-melt effect is very good.
4. Combustion test
High-quality PP-R raw materials are hydrocarbon chain compounds. When the flame temperature is higher than 800 degrees Celsius and oxygen is sufficient, only carbon dioxide and water vapor are released during combustion, and there is no smell and residue during combustion. Inferior PP-R water pipes are mixed with inferior plastics and other impurities, and there will be odor and residue when burning.
The evaluator lit one end of the water pipe with a lighter and the water pipe began to burn.
During the continuous combustion of the water pipe, the appraisers observed that the flame and smoke were white and had no pungent smell, which further proved that the green nano super antibacterial pipe was healthy and safe.
