feel? Polyester is an important variety of synthetic fibre and is the commercial name of polyester fibre in China. It is a fibre-forming polymer, polyethene terephthalate (PET), which is prepared by esterification or ester exchange and polycondensation reaction of refined terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) as raw materials and is prepared by spinning and post-treatment. Polyester fabric is a kind of chemical fibre clothing fabric widely used in daily life. Its greatest advantage is that it has good wrinkle resistance and shape retention, so it is suitable for outdoor products such as outerwear, various bags and tents.
The feel of 100% polyester fabric clothes is not very good. Polyester thin elastic fabric is soft, the thick fabric is generally hard and rough! Generally, it is not suitable for wearing, but sweatshirts are mostly made of polyester. Because the human... less

is mainly used for winding of motors and transformers and other related electromagnetic equipment. Its conductor is mainly copper wire, with a thin insulating layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance, solvent resistance and other properties. Selecting different insulating materials can obtain different characteristics. Several advantages of copper winding wire：
1. Low resistivity: good ductility of copper winding wire: the ductility of copper alloy is 20-40%, and that of electrical copper is above 30%; High strength: the allowable stress at normal temperature is 7~28% higher for copper than aluminum. Especially the stress at high temperature, the difference between the two is even greater.
2. Anti-fatigue: Copper is not easy to break. In terms of elastic index, copper is about 1.7~1.8 times higher than aluminum. The copper winding wire has good stability, and the copper core... less

literally means a wire that uses a copper layer to surround an aluminum core wire. According to usage, ECCA wire can be divided into ECCA wire for signal or communication purposes and ECCA wire for power supply purposes.
ECCA wire has many advantages, which can effectively reduce AC resistance and is very cost-effective. Ac resistance is the main basis of current carrying capacity. According to the skin effect principle, the current per unit area of a single conductor surface is greater than the current per unit area of the conductor centre, that is, the conductor centre with a large cross-section is in the circular area of the same conductor, and the circular centre is smaller than the current passing through the circular, so it is reasonable and economical to use different metal components for the centre conductor and the circular conductor.
Although ECCA wire has been produced and gradually applied, enameled wire industry is still in the stage... less
(1) Quality of injection moulded products: stability and conformity of product size, smoothness of product surface, the utilization rate of product materials, etc.;
(2) Service life: on the premise of ensuring the quality of injection moulded products, the number of working cycles that the table mould can complete or the number of parts produced;
(3) Use and maintenance of table mould: whether it is convenient to use, easy to demould, and the production assistance time is as short as possible;
(4) Maintenance cost, maintenance periodicity, etc.
The basic way to improve the quality of the table mould: the design of the table mould is an important step to improve the quality of the injection mould. many factors need to be considered, including the selection of the table mould material, the usability of the table mould structure, the injection... less

burns?
According to the burn caused by different reasons such as machinery, mould or moulding conditions, the solution adopted is also different.
1. Mechanical reasons: For example, due to overheating of the charging barrel caused by abnormal conditions, the resin is decomposed at high temperature and injected into the product after being burnt, or due to stagnant flow of resin caused by the threads of nozzles and screws, check valves and other parts in the cartridge, the resin is brought into the product after being decomposed and discolored, and the product has black and brown burn scars. At this time, the nozzle, screw and barrel should be cleaned.

But in recent years, the one child policy has come under criticism, even at home, both for the human rights abuses that were inflicted in its name (such as forced abortions) and for the unnatural way in which it has shaped China population. In other developing nations without such onerous family planning, the number of children in each family naturally tapered off as economies grew and educational standards increased. Nature, it turns out, doesn appreciate mucking about by socialist planners.

This kind of accident usually accounts for 50%. In order to avoid the accidents of aluminum magnet wire, besides strengthening the working quality of storage, transportation, and laying off aluminum magnet wire, it is more important to strictly implement the soil movement system. Corrosion of protective layer: electrochemical corrosion of underground stray current or chemical corrosion of non-neutral soil makes the protective layer ineffective and loses its protective effect on insulation.
The solution is to install discharge equipment in areas with dense stray... less
