Abstract
The invention provides a PE plastic bag film production process which comprises the following main steps: stirring materials, performing extrusion film blowing, and printing. The PE plastic bag film production process is simple and feasible, a produced PE plastic bag film cannot be dissolved in ordinary solvents, is small in water absorption property and excellent in electric insulating property.
Description
Technical field
The present invention relates to membrane material production technology, particularly relate to a kind of PE poly-bag film production process.
Background technology
The major function of PE bag and technical indicator PE are poly abbreviations, are that ethene is through being polymerized obtained a kind of thermoplastic resin.Industrially, the copolymer of ethene and a small amount of alpha-olefin is also comprised.Polyethylene odorless, nontoxic, feel ceraceous, there is excellent resistance to low temperature (minimum serviceability temperature can reach-70 ~-100 DEG C), chemical stability is good, and the erosion (the not resistance to acid with oxidizing property) of the most of soda acid of ability, is insoluble to common solvent under normal temperature, water imbibition is little, and electrical insulation capability is excellent; But polyethylene is very sensitive for environmental stress (chemistry and mechanism), and heat-resistant aging is poor.Poly character is different because of kind, depends primarily on molecular structure and density.Adopt different production methods can obtain the product of different densities (0.91 ~ 0.96g/cm3).Polyethylene can be processed with the forming method of general thermoplastic.Be used for manufacturing film, container, pipeline, monofilament, electric wire, commodity etc., and can be used as the high-frequency insulation material of TV, radar etc.
Summary of the invention
The invention provides a kind of PE poly-bag film production process.For realizing object of the present invention, technical scheme of the present invention is as follows:
A kind of PE poly-bag film production process, it is characterized in that, its concrete steps are:
(1) material is stirred
Requirement according to product carries out proportioning to raw material, puts colouring particles and polyethylene into mixer, and colouring particles and poly ratio are 15-20:1;
(2) blown film is extruded
Raw material through the heating and melting of high-temperature pipe 130-180 DEG C, pushes away with the crowded of screw rod in an extruder, and under pressure is 30-50T, by the plastic extrusion melted, through gas overcharging blown film, form film, wind speed is 3-5m/s;
(3) print
Use intaglio printing to print film, print speed printing speed is 8-10m/min, is 25-30g/m by ink amount
2;
Preferably, antistatic master batch is added in the feed in step (1).
Preferably, in step (2), blown film uses cold wind, and temperature is 10 DEG C.
Beneficial effect: the invention provides a kind of PE poly-bag film production process, its key step comprises stirring expects-extrudes blown film-printing, and this manufacturing process is simple, and the PE poly-bag film produced, be insoluble to common solvent, water imbibition is little, and electrical insulation capability is excellent.
Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
A kind of PE poly-bag film production process, it is characterized in that, its concrete steps are:
(1) material is stirred
Requirement according to product carries out proportioning to raw material, puts colouring particles and polyethylene into mixer, and colouring particles and poly ratio are 18:1;
(2) blown film is extruded
Raw material through the heating and melting of high-temperature pipe 180 DEG C, pushes away with the crowded of screw rod in an extruder, and under pressure is 40T, by the plastic extrusion melted, through gas overcharging blown film, form film, wind speed is 4m/s;
(3) print
Use intaglio printing to print film, print speed printing speed is 10m/min, is 30g/m by ink amount
2;
Wherein, step adds antistatic master batch in (1) in the feed, and in step (2), blown film uses cold wind, and temperature is 10 DEG C.
The invention provides a kind of PE poly-bag film production process, its key step comprises stirring expects-extrudes blown film-printing, and this manufacturing process is simple, and the PE poly-bag film produced, be insoluble to common solvent, water imbibition is little, and electrical insulation capability is excellent.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
