Will both the above masterbatch production after mix, ground after mixing, wait be entirely it is powdered after carry out
It is sufficiently stirred, and carries out thawing repeat style, the herbage film is made of 150/30D extruder, the extrusion pressure of extruder
Power is 5MPa, and coextrusion die head is flat shoulder single channel formula, and wind-up roll is extinction type casting roller, and feed block is distributed by stream and selected
Plug, distribution pin, shunt wing plate and melt flow channel composition, the practical β ray of calibrator, winder have surface winding, center winding and
Centre of surface winds three kinds of modes.
Further, the low density polyethylene (LDPE) and linear polyethylene are powdered or granular.
Further, the molecular weight of the polyisobutene LDPE is 350-60000.
Further, described two masterbatch are ground into powder, and are sufficiently mixed according to the ratio of 1:1.
The advantages and positive effects of the present invention are:
1, according to product obtained is matched, effective component is high, and performance is stablized, stretch-proof, light shine, resistance to oxidation.
2, energy consumption needed for producing reduces, and plays the effect of energy-saving and emission-reduction.
3, manufacture craft simplifies, and facilitates production and production, the properties of product of preparation are excellent, and dosage is few, at low cost, Yi Sheng
It produces, viscosity is high, and adhesion coating is uniform, can enhance film-strength, transparency etc..
4, service machine feed block is vdiverse in function, and coextrusion die head can make melt pressure uniformity, extinction type curtain coating
The chill roll of roller double-jacket spiral flow passage type, surface have carried out delustring processing, so that cast film molding is more preferably, appearance and interior
In increased quality, calibrator is continuously measured, as a result precisely, winder functional diversities.
5, nano montmorillonite is added in metallocene linear-low density polyethylene 14%-70%, substantially increases the strong of film
Degree.
