Extruder Screws And Barrels for meltblown nonwoven fabric machine

Meltblown nonwoven fabric is the core material of masks. Meltblown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure and good anti-wrinkle ability. Ultrafine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the meltblown cloth has good filterability, shielding, heat insulation and oil absorption. Can be used in the fields of air, liquid filter materials, insulation materials, absorbent materials, mask materials, thermal insulation materials, oil-absorbing materials, and wiping cloths. Meltblown cloth is the core material of masks. Medical masks and N95 masks are composed of a spunbond layer, a meltblown layer, and a spunbond layer. The spunbond layer and the meltblown layer are both made of polypropylene PP material.


Gram weight: 18g-500g
Wide: generally 160cm and 180mm (can also be determined according to customer needs)


Meltblown cloth uses high-speed hot air flow to draw a thin stream of polymer melt extruded from the spinneret of the die, thereby forming ultra-fine fibers and collecting them on the screen curtain or roller, while bonding itself to become Meltblown nonwovens.
The production process of melt blown cloth is mainly:
1. Melt preparation
2. Filter
3.Measurement
4.The melt is extruded from the spinneret
5. Melt flow drafting and cooling
6. Networking


Meltblown cloth uses polypropylene as the main raw material, and the fiber diameter can reach 0.5-10 microns. These ultrafine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the meltblown cloth has good air filtration. It is a relatively good mask material. In large, medium and small medical institutions, in areas affected by earthquakes and floods, in the high incidence season of SARS, bird flu and H1N1 virus, meltblown filter paper plays an irreplaceable role with its strong filtering performance effect.

Extruder screw and barrel are widely used in the plastic processing industry; they can used in the thermo-plasticit , thermo-set plastic , rubber, elastomer- plastic. We can design targeted screw and barrel according to the different resin grades and formula feature to meet the production and quality demand. They are applied in the plastic extrusion equipments as profile, tube, profile bar, rubber tire, conveyor belt, thin film, sheet, board, wire rod, granulation.

We can make the drawing according to your requirements,like the material, the machine, and the output,etc. And also we can do by your own drawings with our suggestions.

Dia of the meltblown machne screws will be 60 / 65 /90mm and so on.

Main parameters of screw and barrel:

Material 38 CrMoAlA(JIS SACM645); 42CrMo(JIS SCM440)
Hardness of nitrogen treatment HV900°~1100°
Tempering hardeness HV240 ° ~280°
Depth of nitrogen layer: 0.6~0.8mm
Nitrided Brittleness above 1 stage
Surface Roughness Ra0.4 um
Screw straightness 0.015mm
Hardess of surface chromium-plating after Nitriding HV≥950HV
Chromium plating Depth 0.025-0.085mm
Alloy Depth 2.5mm-4mm
Alloy hardness HRC62°~72°
Heating-treatment nitrogen ,electroplated hard -chrome finish,high frequency quenching

Remarks :We can design and manufacture various kinds of screw barrel according to the customers requirement.


Application
1. Parallel twin screw and barrel has the advantage of lower rotation speed, smaller shear stress between the small screw
2. Good plasticization, high productivity, small shear force, stable pressure , less wear and tear and low cost.
3. Parallel twin-screw and barrel is widely used in PVC products processing, especially for the production of PVC products with the output over 350Kg / h, because the parallel twin-screw and barrel costs less than conical twin-screw and barrel while it has more mature technology.
4. Parallel twin-screw and barrel is successfully applied in PVC plate, pipe, profile, pellet and mould, at the same time, it solved the technical problem of low foaming, high foaming, high filling, wear and corrosion.


Packing:

1. Be brushed anti-corrosive oil on screw barrel.
2. Packed with film.
3. Packed in the wooden carton.

Service:

1.After sales service: we will dispatch professional technicians to customer factory for machine installation and training.

2. Our Customer Service Executive will be 24 hours online for you to solve problems.

3. We have introduced South Korea and Taiwan technology with more than 30 years experience. Our machine quality is the best.
