Description
Technical field
The present invention relates to field of packaging material, particularly relate to a kind of woven bag and preparation method thereof.
Background technology
Woven bag, also known as snakeskin bag.Be the one of plastics, packaging, its raw material is generally the various Xylonite raw material such as polyethylene, polypropylene.Knitting tightness refers in 100mm × 100mm cloth, through the radical of weft yarn.Specify in standard GB/T/T8946-1998, " bag is shakeout, upper at sack, lower two diagonal angles place delineation 100mm × 100mm two square; outside square with bag sideline at a distance of 100mm, the warp of range estimation square, latitude radical; average, during counting when settled point last less than one time, by one." define knitting tightness in national standard while, define density tolerances.Knitting tightness depends primarily on wrapped product, is determined by user.
External production main raw material is polyethylene (PE), and domestic production is mainly polypropylene (PP), is that ethene is through being polymerized obtained a kind of thermoplastic resin.Industrially, the multipolymer 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 use 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-absorbent is little, and electrical insulation capability is excellent; But polyethylene is very sensitive for environmental stress (chemistry and mechanical effect), 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 different densities (0.91 ~ 0.96g/cm
3) product.Polyethylene can be processed with the forming method of general thermoplastics (see plastic working).Purposes is very extensive, is mainly used to manufacture film, container, pipeline, monofilament, electric wire, daily necessities etc., and can be used as the high-frequency insulation material of TV, radar etc.Along with the development of petrochemical complex, polyethylene production is developed rapidly, and output accounts for 1/4 of plastics ultimate production.Nineteen eighty-three, polyethylene overall throughput in the world's was 24.65Mt, was 3.16Mt building device capability.
A kind of thermoplastic resin obtained by propylene polymerization.Have isotactic thing, random thing and rule thing three kinds of configurations, Industrial products with isotactic thing for main component.Polypropylene also comprises the multipolymer of propylene and a small amount of ethene.Be generally translucent colorless solid, odorless is nontoxic.The highly crystallized due to compound with regular structure, therefore fusing point is up to 167 DEG C, heat-resisting, the sterilization of goods used vapour is its outstanding advantages.Density 0.90g/cm
3, be the lightest general-purpose plastics.Corrosion-resistant, tensile strength 30MPa, intensity, rigidity and the transparency are all good than polyethylene.Shortcoming is that low-temperature impact resistance is poor, more aging, but can be overcome respectively by modification and interpolation oxidation inhibitor.
Due to goods resource and price problem, there are 6,000,000,000 woven bags in China every year for cement packing, account for more than 85% of bulk cement packaging. along with the Application and Development of flexible container bag, the pack of plastic knitting collection dress is widely used in sea, communications and transportation sacker agricultural prods, in agricultural product packaging, Polywoven Bag has been widely used in fishery products packaging, bird feed is packed, the covering material of plant, the sunshade of proportion of crop planting, windproof, the materials such as hail suppression canopy. usual products: feed woven bag, chemical industry woven bag, putty powder woven bag, urea woven bag, vegetables mesh pocket, fruit mesh pocket etc.
Makeshift tent in tourism, parasols, various traveling bag, travelling bag, plastic braid is had to apply, the covering material that various tarpaulin is widely used in transport and stores, instead of the cotton being easy to go rotten heaviness and knits tarpaulin. and the fence in construction, guard etc. are also widely used in plastic braid. common are: logistics bag, logistics packaging bag, shipping bag, freight transport packing bag etc.
Since developing geotextile from the eighties, widen the Application Areas of plastic braid, be widely used in little water conservancy, electric power, highway, railway, harbour, mine construction, in military engineering construction. in these engineerings, geosynthetics has filtration, draining, strengthens, isolation, the functions such as antiseepage, plastic civil engineering cloth is exactly the one of Geosynthetics.
Polywoven Bag is configured to Polypropylene Bag, polyethylene bag by main raw; Bag at the bottom of seam end bag, tape edge is divided into by method of sewing.Be widely used in a kind of wrapping material of the article such as fertilizer, Chemicals at present.Its main production utilizes plastic raw materials to be flat filament through extrusion film, cutting, unilateral stretching, through obtaining product through knitting device, is commonly referred to as woven bag.
