1 The role of protective clothing In the workplace, people may be exposed to high temperatures, flames, radiation, etc. In this case, they should be given appropriate protective clothing, so it is necessary to properly select such protective clothing, the purchaser should know The protective effect of this protective clothing. The role of this protective clothing is to act as a fire shield when exposed to a flame, ie a barrier between the wearer and the flame, isolating the heat emitted from the flame heat source. It should also protect the wearer when they escape heat and flame burning. The protective effect of such protective clothing for the wearer should be consistent with the potential hazards they face during exposure, escape, and the service life of the protective clothing. They should not burn, melt, or break when in contact with flames. . It should also provide mechanical protection against tears, abrasions, open seams, and, depending on the intended use, it also needs to provide protection against weather changes and chemical substances. 2 protective clothing production steps The value chain of the high-temperature flame protective clothing begins with the fibers; the fibers are spun into yarns, the yarns are then made into fabrics, and the fabrics are finally made into protective clothing. (1) Fiber. Fiber is the basic element of fabrics and other textile structures. The meta-aromatic polyamide in the chemical family is a kind of fiber widely used in high-temperature flame protective clothing. It is characterized by high strength, especially excellent high-temperature flame resistance. Well-known meta-aramid fibers for high-temperature flame protection garments include Kermel, Conax, Conex, and Nomex. Polyamide (Nomex). (2) Yarn. The original form of fiber can not be used for protective clothing. In order to achieve this goal, they must be converted into yarns. The process of forming yarns is spinning, which is to twist fibers together to form yarns. Yarns are used to weave fabrics and can also be used to make threads that sewn together to form protective clothing. Meta-aramid fibers can be spun into meta-aramid yarns. (3) Fabrics. The change from yarn to fabric is a physical change. When flame-retardant fibers are used to produce high-temperature flame protective clothing fabrics, other factors should be considered in accordance with the ultimate use of protective clothing. These factors include structure, weight, comfort, strength, elasticity, and color. There are also some factors that need to be considered, such as water and chemical resistance, visibility and anti-static. Blending fabrics made of meta-aramid yarns with other special high-quality fibers can provide these required functions in the fabric and use it in protective clothing during the second phase of the value chain. (4) protective clothing. The protective clothing manufacturer designs the features that the buyer may require into the protective clothing, such as the type and location of the pocket and the threshold system. For high temperature flame protective clothing, the designer must ensure that the wearer is designed to protect the body's upper and lower torso when the wearer is accidentally surrounded by flames, including arm to wrist and leg to foot. Lines used to sewn key parts of protective clothing should also be made of meta-aromatic polyamide or other high temperature resistant yarns. If the suture used for the main suture of the protective suit does not possess such characteristics, the flame will melt or burn upon contact with the flame, and the protective clothing will be torn apart, possibly exposing the wearer to direct contact with the flame heat source. Supporting Equipment of Plating Line
Supporting equipment of plating line such as filter, rectifier,etc.
It includes: Rectifier system,DC conductive copper bar or cable, Filter system, Filter piping, Post-treatment dryer, Water chiller, Ultrasonic generator, Cooling water tower, Stainless steel heat preservation water tank (with level gauge and alarm) and horizontal water pump and piping system, Circulating pump and piping system between chiller and cooling tower, Secondary wiring of supporting equipment,Coarse regeneration device, Automatic dosing and conductivity meter.
In order to complete the electroplating process according to the process requirements, it is not enough to have a power supply and a plating tank, and there must be some auxiliary equipment to ensure the normal production of electroplating. Including heating or cooling equipment, cathode moving or stirring equipment, plating solution circulation or filtering equipment, and necessary accessories for plating tanks such as electrode rods, electrode wires, anodes and anode baskets, plating hangers, etc.
