Greening special non-woven film mulching

In recent years, China's non-woven fabric processing industry has developed rapidly, the use of spunbonded non-woven fabrics has become more and more extensive, and its demand has also shown a rapid growth trend.

1. General parameters:

Production: 1500 ~ 3000 t / a
Power consumption: 800 kw / t
Product Quantitative: 10～230 g/m2
CV value: ≤5%
Aspect ratio: 1.5:1 to 1:1
Cloth condition: The cloth surface is in good condition, and there are basically no hanging wires or broken wires.

2. Equipment production process:

(1) The automatic suction device sucks the PP slice from the lower bin into the high bin.
(2) The PP raw material enters the main screw extruder together with the masterbatch, and the electric heating device outside the main screw partitions and heats the slice.
(3) The melt is filtered through a filter and metered out by a metering pump.
(4) The melt is ejected from the spinneret.
(5) The circulating cooling air draws the tow and sends the tow to the web curtain.
(6) Consolidate the laid fiber web.

3. Introduction to some components

(1) Low level silo: 3-4m3 (capacity), made of stainless steel.
(2) Suction tube: inner diameter 40mm, metal support frame on the inner wall.
(3) High silo: 0.6m3 (capacity), made of stainless steel.
(4) Automatic suction device: 220～400 kg/hr
(5) Color masterbatch addition: ≤10%
(6) Main screw:
Screw form: Single screw type, automatic adjustment of speed.
Heating form: five temperature zones, heated by electric heating package.
(7) Return screw:
Screw form: single screw form.
Heating form: five temperature zones, heated by electric heating package.
(8) Metering pump: Transmission: Variable frequency control.
Working capacity: 150 ~ 250cc / r
(9) Spinneret:
Aperture: φ0.42mm
Hole density: 3910 holes / meter (10) circulating cooling air drafting system:
Drafting fineness up to: 3dtex
The cooling temperature is controllable, the air volume is controllable, and the regulating valve controls the uniformity of the net.
(11) Rolling mill:
Heating form: heat transfer oil heating.
Surface treatment: nitriding treatment.
Flower stick embossing: one-line pattern, cross pattern, dot pattern.
