Polishing Wax/polish compound/polish paste belongs to chemical products and commodities, but in fact it is made by physical mixing and heating. Polishing wax also produces grinding, smoothing, smooth, and bright effects through physical movement during use, thereby playing the role of polishing and polishing. Polishing wax has a wide range of uses. It not only refers to the polishing and polishing of metals, but also the polishing of resins PU,PA, plastics, as well as hardwood furniture and appliances.
Polishing is divided into rough polishing, medium polishing, fine polishing and mirror polishing.For metal utensils and utensils of different materials, it is necessary to choose a suitable polishing wax to play a real role and an ideal effect.

Pipe extrusion process includes the following production processes
Steel pipe extrusion process includes the following production processes ①blank: Round billet after stripping, length cutting, drilling, machining and cleaning, you can form a hollow tube blank ready. ② billet heating: According to different types of steel, can be divided into three heating stages, to ensure that the production process to meet the appropriate temperature. ③ preheating: a rotary hearth gas stove will be used for the first step of heating, the billet preheated to 700 ℃ ~ 900 ℃. ④ Induction heating unit (first stage): The first group of induction heating unit heats the billet to the required temperature for the expanding process, which is about 1100-1250 ° C. The specific temperature value is determined according to the steel for production. Induction heating unit using low-frequency heating. ⑤ billet lubrication: before reaming the glass fiber lubrication. ⑥ reaming: the hole has been drilled before the round billet, you must first start from a smaller pilot hole reaming, until the hole eventually reached the inner diameter machining accuracy requirements. The main features of the above process and equipment are: Complete all reaming and upsetting operations by two double-acting cylinders Automatic taper cone / unload to the center of the reaming machine Automatic lubrication of the ingot surface, Glass fiber can be automatically inserted into the guide hole. The reaming cylinder and reaming needle are automatically cooled. ⑦ induction heating unit (second stage): a second set of induction heating unit used to reheat the billet after the billet reaming. According to the normal operation of conveying and conveying system, it is required to heat the middle billet to 1200 ℃ or according to the required temperature of the material. ⑧ Extruder: Billet installed on the extruder, processed into steel by extrusion. Extruder auxiliary system is responsible for feeding, replacement of extrusion die, extrusion pad recycling and pressure head separation and more. The main features of the above process and equipment are: .Under separate control of the external extrusion mandrel ;.Extrusion process can be used floating, fixed and relative speed control and a variety of plunger working mode ;. Has a fully automatic tube saw And extrusion die automatically replace the device ;. Pressure head and the extrusion pad automatically separated ;. The mandrel automatically replaced ;. Extruded tube automatic cleaning ;. Billet automatically feeding, while achieving glass fiber lubrication. ⑨ cooling pool: cooling pool arranged on the side of the output roller for rapid cooling of steel pipe. ⑩ cooling bed: When the need for air cooling, the steel pipe can be transported to the cooling bed.
