缠绕罐 Winding tank

缠绕罐成型工艺采用螺旋挤出缠绕技术,品质达到国际先进水平,主要工序有罐体挤出缠绕、外部焊接、內缝焊接、管口安装等。  1、罐体挤出缠绕制作  罐体碰焊就是用PPH螺旋挤出缠绕机组使PPH颗粒料加工成罐体成型的工艺。系统采用将PPH颗粒热熔后挤出后再钢制模具上缠绕成罐体的工艺。  2、外部焊接制作  外部焊接就是用进口自动挤出焊接机组使储罐应力最大部位实现大焊缝一次焊接成型的工艺。将与罐体性质相同的全新PPH颗粒料热熔在大焊缝处,与罐底、罐体成一体。  3、内部焊接制作  内部焊接是采用自动长臂挤出焊接工艺,是所有工序中最重要的一步。将与罐体性质相同的全新PPH颗粒料热熔在内部焊缝处,与罐底、罐体成一体,原理与外部焊接相同,只是其设备不同。  4、管口安装制作  管口安装是最后一道工序,等同于底部焊接的缩小版本,就是用进口小型自动挤出焊接机组,将接管与法兰焊接成型,再采用开孔器在罐体上开相应尺寸的口径,最后采用德国MUNSCH手提挤出焊接。

产品描述

Wide range of applications

Polypropylene storage tanks are mainly used in chemical, metallurgy, electroplating, chemical fiber, printing and dyeing, environmental protection, petroleum, electronics, medicine, food, grease, light industry, acid, pickling, battery materials and other industries.

 

First, the tank extrusion winding production

Tank welding is a process in which PPH pellets are processed into a can body by using a PPH spiral extrusion wrap unit. The system adopts a process of extruding PPH particles after hot grinding and then winding the steel mold into a can body.

 

Advantages of extrusion winding:

◆ Production efficiency is 5-8 times higher than manual.

◆The product has good integrity, no feeling of contact and corrosion resistance. Good sand resistance. ◆ The product is flat and beautiful, and the thickness of the tank is reduced. ◆The size and shape of the product are not used.

◆ Product strength amount of pellets plus engineering type, good anti-aging performance.

=, external welding production

 

       External welding is the process of using the imported automatic extrusion welding unit to achieve the maximum welding stress of the largest part of the tank. The fully-broken PPH pellets having the same properties as the tank are hot-melted at the place of the large welding, and integrated with the bottom of the tank and the tank.

 

       Bottom welding process features:

 

       ◆Mechanization, high degree of automation, and stable product quality.

 

       ◆The welding can be designed according to the stress characteristics of the product, so that the integral of the weld can be achieved.

 

       ◆The product has good integrity, the weld seam is integrated with the mother body, and the machine is corrosive and resistant to lag.

 

       ◆It can reduce the flash and the seams are flat and beautiful.

 

       ◆ In the PPH fake grain family, the source and the home line absorb the other, prevent aging, and the life is long. Third, internal welding production

 

       The internal swing is an automatic long arm extrusion bursting process, which is an important step in all processes. The full-quality PPH, which is in line with the nature of the tank, will be in the building. Compared with paving the body, the principle is different from the external one, but the equipment is different.

Internal welding process characteristics

 

       ◆Mechanization, high degree of automation, and stable product quality.

 

       ◆The shore hardness specification can be designed according to the stress characteristics of the product, so that it can fully exert the integrity of the weld.

 

       ◆The product has good integrity, and the weld seam and the mother body are integrated with corrosion resistance and good leakage resistance.

 

       ◆ It can reduce the flashing edge and make it smooth and beautiful.

 

       ◆ Add UV absorber to PPH pellets to prevent aging and prolong service life

 

Fourth, the nozzle installation and production

 

       The nozzle installation is the last process, which is equivalent to the small plate point welded at the bottom. It is an imported small automatic extrusion welding unit, which is formed by forming the joint with the flange and then using the hole opener to open the corresponding size on the tank. The caliber is then welded by the German MUNSCH portable extruder.

 

       Pipe installation process characteristics

 

◆Mechanization, high degree of automation, and stable product quality. ◆The weld seam of the mouth and the body of the tank, the welding impact is high. ◆The division reduces the flashing edge, and the welding is smooth and beautiful.

The difference between PP polypropylene and PPH polypropylene

Polypropylene is a non-toxic, odorless, tasteless, milky white high crystalline polymer with a density of only 0.90-0. 91g/cm3, which is one of the lightest varieties of all plastics. It is particularly stable to water in water. The water absorption is only 019, and the molecular weight is about 80,500,000. Good formability, but due to the large shrinkage rate (196-2.5%) thick-walled products are easy to sag, for parts with higher dimensional accuracy, it is difficult to meet the requirements, the surface gloss of the product is good.

The chemical stability of polypropylene is very good. In addition to being able to be smashed by concentrated acid and irritating membranes, it is stable to various other chemical reagents, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and oxidized cellulose can cause polypropylene explosion. It softens and dissolves, and its chemical stability increases with the increase of crystallinity. Therefore, polypropylene is suitable for making various chemical pipes and fittings with good anti-corrosion effect.

Non-toxic, odorless, low density, strength, system, hardness and heat resistance are better than low-pressure polyethylene, can be used at around 100^C. It has good dielectric properties and high-frequency insulation and is not affected by humidity, but becomes brittle at low temperature, not wear-resistant and easy to age. Through the production of general mechanical parts, corrosion-resistant parts and insulation parts. Common organic solvents such as acids and bases have little effect on it and can be used in food utensils.

PPH is a high molecular weight, low melting rate homopolymeric polypropylene fiber. It is modified by B to have a fine structure, which has excellent chemical resistance, high temperature and excellent butterfly resistance. It also has excellent impact resistance at low temperatures.

Ordering, installation instructions

The diameter of the tank is fixed due to the mold.

●The volume and structure of the tank, flange orientation, etc. can be customized according to customer requirements.

Please submit the working condition parameters to Parkson's design team as much as possible when ordering the tank.

Plastics have different shrinkage rates due to temperature. The detailed dimensions of the equipment and the basic dimensions of the installation are subject to the actual product.

Taking into account the production error, the equipment foundation, pipelines, etc. must wait for the product to be poured into the site and then watered and connected.

If you have special requirements for the equipment, please ask at the time of ordering.

● Do not tighten one side when flange connection, so as to avoid deformation of the flange surface.

Do not pass the weight of pipes, valves, etc. on the flange of the tank to avoid cracking of the flange.
