Therefore, the development of the power industry is closely related to our life. The cables we usually use usually include Copper Winding Wire(XINYU-ENAMELEDWIRE) http://www.xinyu-enameledwire.com/
and aluminum winding wires, but copper winding wire is used more frequently. Why is this?
In fact, compared with aluminum winding wires, the resistivity of copper winding wire is lower. Under the same conditions, the resistivity of aluminum winding wires is about 1.68 times higher than that of copper winding wire. In terms of oxidation resistance, the performance of copper winding wire connectors is more stable, and accidents will not occur due to oxidation. The situation of aluminum winding wires is different. Its joints are very unstable, and accidents often occur due to increased contact resistance and heating due to oxidation, so the accident rate is much higher than... less

are regarded as the core weapon in the water treatment industry. So is the filtration principle of ro physical or chemical? Next, I will tell you briefly about the relevant knowledge about reverse osmosis spare parts.
Ro spare part is a medium. It separates the solvent (usually water) in the solution through reverse osmosis membrane (a semi-permeable membrane) by pressure, which is opposite to the permeation direction. Reverse osmosis method larger than osmotic pressure can be used to separate, purify and concentrate the solution. The main separation object of the reverse osmosis membrane is the ion range in solution. This membrane separation technology relies on the separation process of solvent and solute in solution under pressure by a permeable membrane. Infiltration is a physical phenomenon.
Definition of reverse osmosis:
When the same volume of dilute solution and concentrated solution are respectively... less

and the technical level of operators.
1. Design of household products
Designers should first fully understand the user's use requirements and working conditions, the stress of household products, and then select appropriate materials according to the use requirements and working environment to understand their material properties.
The requirements for dimensional accuracy of household products should be reasonable, otherwise it will cause unnecessary troubles to the design of household product mould, mould processing, formulation and management of process conditions, and will also cause a large number of unqualified products.

. As a user, how to reduce the wear of the agricultural chain is not only beneficial to improving the working efficiency but also greatly improves the service life of the chains themselves. The following is a brief introduction to how to reduce the wear in the use of the agricultural chain. There are mainly three points:
1. Please try to keep the verticality of the agricultural chain between the large-toothed disc and the flywheel when changing speed.
2. When changing speed, consider the road conditions in advance. For example, when going uphill, shift up early to avoid excessive force on the agricultural chain when changing gears.
3. Please change to the smallest gear before parking, so as to avoid speed change when still.
In addition to reducing the wear and tear of the agricultural chain in use, regular maintenance is also very helpful for the increase of its service life, in... less

According to the sublimation characteristics of some disperse dyes, disperse dyes sublimated at 150~230°C are selected and mixed with slurry to form "colour ink". according to different design pattern requirements, the "colour ink" is printed on transfer paper (this is a special paper, so it is called transfer paper). then the transfer paper printed with pattern patterns is closely contacted with the fabric. under the condition of controlling certain temperature, pressure and time, the dye is transferred from the printing paper to the fabric and enters the fabric through diffusion, thus achieving the purpose of colouring and becoming transfer printing fabric(WANSHIYITEX) https://www.wanshiyitex.com/product/transfer-printing-fabric/

is characterized by softness, lightness, thinness, moisture absorption and permeability, smooth surface, etc. Lightweight fabric has high shrinkage. In order to ensure the dimensional stability of ready-made garments, they are usually pre-shrunk before cutting. At present, silk garment enterprises usually use steam preshrinking and washing water preshrinking for preshrinking.
Let's talk about the cutting process of lightweight fabric. Generally, thin silk fabrics are smooth and have little friction force between fabrics. In order to prevent the fabrics from moving in series during cutting, clamps are easy to use to fix and prevent the upper and lower layers from moving and being scattered and dislocated. The cutting knife should be sharp, the rigidity of lightweight fabric is poor, and the pushing knife should not be too strong, otherwise, the garment pieces will be dislocated and deformed, and the cut fabric should be *******... less
