The higher the quality inspection department in a wire and cable enterprise, the better the quality of the wire and cable produced by the enterprise and the more trustworthy it is. So what kind of cable is of good quality? What are the quality inspection indicators? The following ECCA Manufacturer(XINYU-ENAMELEDWIRE) http://www.xinyu-enameledwire.com/
will give you a detailed introduction.
1. Conductor DC resistance measurement:
Conductor cores of wires and cables mainly transmit electric energy or signals. Conductor resistance is the main index to measure its electrical performance. When AC voltage is applied, the core resistance is larger than DC voltage due to skin effect and proximity effect, but when the power frequency is 50hz, the difference between core resistance and DC voltage is very small. At present, the standard can only require whether the DC resistance or resistivity of the detection... less

.
Many families lack the anti-freezing consciousness of the water purifier, which often causes the pipes of the water purifier to be frozen out and the inside of the machine to be damaged, thus preventing the normal use of the water purifier.
It should be noted that the lower temperature and less water consumption at night reduce the fluidity of water in the pipeline, resulting in the water in the pipeline is easy to freeze. Once the pipeline freezes, it is likely that the water pipe will freeze and crack and the filter element of the water purifier will be damaged.
Therefore, when sleeping at night, it is suggested to close the water gate, reduce the burden of water pressure on the water purifier as much as possible, and drain the residual water in the water purifier.
The second move: outdoor water purifier should do a good job in anti-freezing... less

with high quality, excellent service and reasonable price rather than just looking at how low the price of water filter spare parts is.
Now consumers are becoming more and more rational in purchasing products. The first factor to consider when purchasing water filter spare parts is always the quality of the products. The quality of the products does not pass muster. Even if the price of the products is lower and the service is better, consumers will find it difficult to make do with them. Moreover, crude and shoddy products are sold at low prices in the water filter market. Cheating consumers with shoddy products and false propaganda will greatly affect the image of the entire water filter industry, shake consumers' purchasing confidence, implicate other water filter enterprises that follow the market rules and do products reliably, and easily create the impression that... less

is a relatively common phenomenon. It not only affects the appearance of mould, but also directly affects the overall quality of mould. Therefore, rusting of crate mould is a problem that cannot be ignored. The following are the analysis reasons and measures for your reference.
The reasons for the rusting of the crate mould are as follows: 1. Products of decomposition of moulding materials. 2. The resurgence of the mould. 3. Hand sweat.
Relevant analysis on rusting of crate mould:
1. The most common corrosion of mould caused by products (gas, residue) decomposed from moulding materials. In order to prevent the mould from rusting, the most widely used method is to chrome-plate the mould cavity, but chrome-plating cannot fully solve the problem, because the decomposed products also corrode the deep part of the pin hole. These are the places that cannot be plated.
2. When the mould cools below the moisture regain point, moisture... less

, and the requirements are different according to different processing technologies. The situation will be different when it is produced. However, bending deformation is a common problem in furniture mould processing. Why is this so?
A series of situations may occur during the customization of furniture mould processing. In fact, one of the phenomena that we have to face is the bending deformation of furniture mould. So during the whole processing, in addition to the final requirements or installation, the processing of furniture mould and the performance of equipment should also be considered. In this case, more fluidity of furniture mould processing should be considered. Then why do some bending deformation occur during furniture mould processing?
1. Mould itself

have been used for a long time, and the surface is prone to carbon deposition and oil stains. How can they be easily removed?
If there is a carbon deposit on the palm oil chain, chemical and mechanical methods can be used to remove it without damaging the palm oil chain. In the former, palm oil chain are directly immersed in the prepared chemical solution, and the parts are taken out after the carbon deposit softens and loosens, erased with a brush or cotton thread, and then washed with hot water. The latter is to remove carbon deposit with tools such as metal brush and shovel knife. Although it is simple, it is difficult to completely remove the carbon deposit.
If the palm oil chain is contaminated with oil instead of carbon deposit, organic solvent and alkaline solution can remove it, so that the palm... less

is a flame retardant fabric made by processing cotton and nylon blended fabric with flame retardant technology. According to the general requirements of cotton nylon fabric on the original grey fabric, the nylon content should not be higher than 20%, and what we usually see is 88% cotton fibre +12% nylon fibre.
Polyamide fibres such as nylon generally have a melting point of 215℃, a decomposition temperature of 315℃, and an ignition point of 530℃. nylon (nylon) fibres are considered to have self-extinguishing properties because their melting points are quite different from the ignition point temperature, and they are easy to melt and drip during combustion, thus they are separated from the supply of goods and do not burn. The requirement of flame retardant for cotton and nylon fabrics is that nitrogen and phosphorus flame retardants have a good effect on polyester and cotton fabrics, but the effect on... less
