Guang Zhou Factory BFE99 PP CZPTblown Nonwoven Material Creating CZPT Generation Line for medical face mask use
HangZhou Ningwei CZPT and CZPT Co.Ltd. is a maker of meltblown nonwoven material production line in HangZhou China.
Introduction to the composition of the generation line
Entirely automated feeding→melt metering pump→melt filtration→spray plate assembly→receiving network→electrostatic electret 1→electrostatic electret 2→ on the internet slitting → on the internet winding
Manufacturing method demonstration
CZPTpropylene pellet feedstocks are divided into one particular-element and two-element.
A. One-component uncooked resources are raw components without having incorporating any additives.
B. Two-element feedstock divided into polypropylene (pp) pellets + electret masterbatch
The primary position of the electret masterbatch is to concentrate and store static electricity to achieve the absorption of fine dust particles.
The heating part of the equipment is: extrusion technique, melt metering pump, soften nozzle and very hot air compressed air.
This equipment need to be operated by a specialist captain, non-captain you should do not commence the equipment, to make certain risk-free production.

CZPTmer Feeding
The machine is geared up with an automated vacuum suction and feeding system, the polymer is normally created into small spherical and granular slices, the vacuum is opened, the material can be fed into the extruder outfitted hopper. If the content in the hopper is low, fill the hopper quickly, otherwise the substance will be damaged and the meltblown fabric will sooner or later grow to be skinny or not mesh.
CZPT extrusion
In the feed end of the screw extruder, the polymer slices and additives and other needed raw materials, soon after full mixing into the screw extruder, heating into a melt, spend attention to the heating temperature should be modified in accordance to the characteristics of the uncooked components, can be set according to the parameters recommended by the makers, or can be altered in accordance to the genuine generation demands, so that the concluded product can meet the specifications of use.
Fibre formation
The filtered thoroughly clean melt need to pass through the filter screen, and then evenly fed into the spinneret, so that the extrusion volume of each and every spinneret gap is the very same, if the amount of spout is drastically lowered or can not attain the normal extrusion quantity, it is needed to quit and check whether there is a fault, examine regardless of whether the filter screen is blocked or not, and instantly eliminate the difficulty so as not to harm the extrusion gear. When getting rid of the issue of the extruder, you can check out the filter plate of the spinneret, you can notice regardless of whether the holes on the filter plate can not flow effectively the melt of debris there. The fibers are extruded by facet winds that pull the soften out of the spinneret holes and then cooled to sort fibers.
CZPTtrostatic discharge
PM2.5 particles are isolated in two ways: mechanical blocking and electrostatic adsorption. Between them, mechanical blocking is the use of mask fiber filtration substance its personal small pore space to block the invasion of germs and viruses, this mechanical blocking effect on the particle dimension of considerably less than 1μm particles filtering impact is quite inadequate, can not perform a purifying role. Therefore, strengthening the filtration efficiency of the mask meltblown filter media can be attained by increasing the electrostatic adsorption ability of the mask. To increase the electrostatic adsorption ability of the mask, meltblown nonwoven filter material is necessary for electropole remedy. The electret treatment method will provide a large volume of electrostatic demand to the fiber surface, employing electrostatic adsorption to capture wonderful particles, can boost the filtration effectiveness, and does not increase respiration resistance.
Slitting and winding
At the end of the line there is winding equipment. Cut and wind the fashioned meltblown nonwoven material to the dimensions required for packaging. The winding has a tension manage gadget that keeps the winding in a stable state at all occasions. The length in between the cutters is the width of the nonwoven fabric. The distance between the cutters can be altered according to the generation demands and the quantity of cutters can be organized.
