Meltblown fabric extruderFunction

Meltblown nonwovens are20Century50First successfully developed in the United States in the decade, and China also carried out research in the early60Decade. It is made of polypropylene chips with a high melt index directly spun into cloth, which is akind ofhigh-tech product. Currently, the annual output in the United States is approximatelyl5ten thousand,tChina's annual output is5000t

Meltblown extrusion fabricThe production process is: Polypropylene chips(FR400-1200)are melted by a screw extruder, and extruded through spinnerets to become fibrous, and under the blowing of high-speed(13000m/min)hot air flow, it is subjected to strong stretching to form extremely fine short fibers. These short fibers are adsorbed on the forming web, and because the fibers remain at a relatively high temperature after the web is formed, the fibers are bonded to each other to form meltblown nonwovens. Finally, they are rolled and packaged.

The composition of meltblown nonwovens includes: 1, screw extruder; 2, metering pump; 3, meltblowing device; 4, receiving net; 5, winding device; 6, feeding device.

The meltblown nonwoven continuous production line is about 6m high, about 5m wide, and about 20m long. Its production equipment, meltblown fabric extruder: the screw diameter is generally 100~120mm, and the length/diameter ratio is 30. The purpose is to melt the chips.

Summary of Experience with Failed Colin Column Balance Adjustment

Analyzing the causes of errors and summarizing lessons learned during work is an important way to improve work efficiency. Fault case: A Hetian injection molding machine's Collin column broke. The Collin column was replaced and the balance was adjusted, without needing any special tools.


Injection Molding Machine Accessories: Detailed Analysis of Common Temperature Problems!

Injection molding machine accessories. In co-ordinated control, the direction of the temperature sensor in the mold is critical. When placing the temperature sensor, the user must consider its shape, structure, and the direction of the cooling channels. In addition, the temperature sensor cannot be placed arbitrarily; it should be placed in an area that has a critical effect on the quality of the injection molded product. There are many ways to connect one or more high-temperature mold temperature controllers to the controller.


Injection Molding Machine Accessories: Standard Maintenance for Injection Molding Machines

Injection molding machine accessories. Everyone should formulate appropriate daily, monthly, and annual maintenance plans based on the condition of the equipment itself, and carefully implement them for each machine according to the plan. Before using the equipment every day, we should check whether each part of the equipment is normal, such as whether the machinery is working normally, whether the heating conditions of each part are normal, whether the circulating water pipes are leaking, whether the emergency stop button can cut off the motor power supply, etc.


What should be noted when repairing a faulty piston rod?

Piston rod failure is normal. The key is to pay attention to the precautions during specific maintenance. If non-professionals perform maintenance, many problems may arise. If possible, choose professional personnel. Maintenance efficiency and its own use value will be higher. We recommend that everyone should understand the following precautions when understanding piston rod maintenance.


What are some applications of piston rods?

In fact, even if we don't mention it, everyone should know quite a bit about piston rods. Of course, to ensure the efficiency of the piston rod, we must guarantee its performance and quality. If more friends are interested in this field, you can also Tel us to discuss your views, I believe this will be helpful to our work.


Connecting structure of piston rod and piston and how to choose piston rod

Piston rods offer significant advantages in practical applications, and the connecting rod structure of the piston is also unique. When used in combination, it is essential to carefully select hydraulic cylinders that demonstrate good operating and production performance. Such products will be highly reliable. The connection structure between the piston rod and piston, and the manufacturing method of the hydraulic cylinder with this piston rod, are essentially the same.


What does the mold pull rod spacing mean in the injection molding machine parameters?

The actual usable area of the template: the greater the distance between the ejector rods, the greater the actual width and height of the grinding tools that can be accommodated. Because injection molding machines need to install plastic injection molds between the moving template and the fixed template, plastic products can be processed. If the mold is to be installed between the two templates, it must pass through two adjacent ejector rods, so the shape of the mold must be smaller than the spacing between the ejector rods.
