Tourmaline is a common product in our life because its appearance greatly facilitates our life. In order to use electrical appliances in normal use, it needs the help of wires. As a necessity in our life, electric wires have great influence. The electric wire is important equipment for power transmission and the development of electric wire. We have all kinds of wire equipment, and the upgrade of wire is also very fast. Copper and aluminum are one of the more common wires, and its usage is very large. We will introduce how to distinguish the quality of copper and aluminum wires.
ECCA wire refers to a copper wire with aluminum core as the main body and a certain proportion plated outside. The main function of such wires is to transmit signals and can be used as coaxial cable conductors and electrical... less

For the mould of the aluminum solid panel, the extrusion moulding can be carried out by an extruder only by processing moulding holes on the mould. For aluminum hollow slab, the mould is composed of an upper mould and a lower mould. The lower mould is processed into the shape of aluminum profile, while the upper mould is processed into a hollow core. Then the upper mould core is fixed in the cavity of the lower mould. At the same time, a welding chamber is designed between the upper mould and the lower mould.
The upper mould is also provided with a shunt hole through which aluminum flows to the welding chamber. The aluminum is welded again under high temperature and high pressure to extrude the mould hole to become the aluminum hollow panel we need. Because the mould used for the... less

The advantages and disadvantages of injection products involve thermophysics, thermodynamics, rheology, heat transfer, physical and chemical changes accompanying the process, especially phase changes, correct mechanical design and implementation of the best process.
In injection moulding, how to determine the injection cycle is not only related to the quality of the product but also affects the yield and cost of the product. The necessary heat is transferred from the plastic melt injected into the mould cavity to make it become solid so as to be taken out of the air cooler mould without deformation. Therefore, to correctly estimate the injection cycle is the main process parameter that should be determined in injection moulding.
1. Close mould pressing: in principle, the total pressure of the plastic injected into the mould should be greater than that of the... less

It has small density, light fabric, good elasticity, resistance to fatigue damage, good chemical stability, alkali resistance and acid resistance. Therefore, when washing nylon fabric, care must be taken not to use acidic detergent.
Uses: Nylon is mainly used in filament, knitting and silk industries because of its wear resistance. And staple fiber, mostly blended with wool or wool type chemical fiber, made of gabardine, vanillin, etc. In addition, it has become the best material for many products in industry, such as cord, fishing net, carpet, rope, conveyor belt, screen, etc.
Polyester fiber is often referred to as polyester. Polyester fabric is a kind of chemical fiber clothing fabric widely used in daily life, which is suitable for making coat clothing. Its luster is bright, but it is not soft enough. It has a sparkling effect,... less

After the plastic labels are torn off, it is difficult to remove the marks left by the adhesive sticker on the pots or glassware. Wiping with wet cloth or knife will often leave marks. Here is how to remove the marks left by the plastic labels.
1. Use hand cream to remove adhesive. The hand cream contains a certain amount of surfactant, which can quickly penetrate between the adhesive and the surface of the object, thus achieving the purpose of removal.
2. For self-adhesive marks on the surface of hard objects, nail polish remover can be applied to the surface of objects, and then gently wiped with a soft cloth. Because nail polish remover is highly corrosive, it cannot be used on the surface of articles that are... less
