Abstract
The invention relates to the field of a woven bag production process, and in particular relates to a preparation method for a woven bag for cement packaging. The preparation method comprises the following steps: (1) drying and stirring; (2) extrusion molding; (3) drawing and rolling; (4) circular knitting; (5) film-blowing and rolling, and punching of micro pores; and (6) printing, cutting and sewing. The surface of a drying plate in the step (3) is coated with castor oil, and a film-blowing raw material in the step (5) is a mixture which is obtained by mixing low-density polystyrene and polypropylene in a preparation being (1:1.5) to (1:2). According to the preparation method, the toughness of the woven bags is improved, and a fracture phenomenon in subsequent production is prevented, so that the woven bags are not fractured when cement is packaged; and the castor oil is coated on the drying plate, and is coated on the surfaces of flat wires, so that the ductility of the flat wires is improved, and the rolling and circular knitting of the flat wires are convenient.
Description
Technical field
The present invention relates to woven bag production technology field, a kind of cement packing woven bag preparation method.
Background technology
Woven bag is the one of plastics, packaging, and various Xylonite raw material such as its raw material usually polyethylene, polypropylene etc. adds
Upper additives.Production line of plastic woven bag flow process is usually: PP, PE material or reworked material → dry blender → wire drawing machine
→ winder → circular weaving machine → bag cutting machine → sack closer → printer → PP woven bag → baling press.Cement is lived due to its character
Jump, process so the woven bag of packaging cement has to pass through special process, so that its satisfied packaging demand.
Summary of the invention
In order to make up the deficiencies in the prior art, heretofore described a kind of cement packing woven bag preparation method, improve
The toughness of woven bag, i.e. prevents the phenomenon of rupture in subsequent production, makes again will not ftracture when encapsulating cement.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cement packing woven bag preparation method, including
Following steps:
(1) be dried stirring: be 40 by proportioning～50% polypropylene, 20～30% polystyrene, 15～20% molybdenum bisuphide and
10～15% Merlon put into dry mixed in dry blender, baking temperature is 200～250 DEG C, and drying time is
25～45 minutes；
(2) extrusion molding: be dried the raw material after stirring and be inhaled into barrel, through cutting of the heating of barrel and screw rod and machine barrel
Cut, be then extruded into thin film by extruder head, while thin film extrusion, utilize water cooling, water temperature to maintain 15～20 DEG C；
(3) wire drawing rolling: thin film is cut sub-wire by sub-wire cutter, and through the toughness formation flat filament of drying-plate heating raising silk,
Again by receiving silk machine receipts silk rolling, the temperature of drying-plate heating maintains 50～70 DEG C；
(4) circle is knitted: the lacing of rolling utilizes circular weaving machine be made into cylindrical shape woven bag, then by winder rolling；
(5) blown film rolls, beats micropore: rolled its surface blown film by inflation film manufacturing machine by the cylindrical shape woven bag of rolling, blown film
After woven bag first pass through the cooling of cool wind box, cool wind box temperature is 15～25 DEG C, cool time be 25～
45 seconds, then cool down through cooling twice bellows, cooling twice box temperature is 1～5 DEG C, cool time is 5～10 seconds,
Micropore beaten by recycling roll；
(6) print, cut, sew: beat the woven bag after micropore and by press printing trade mark and produce annotation, then profit
Cut into the woven bag of a rule with Cutting machine, finally by sewing device sewing bag mouth, eventually become finished product woven bag.
Preferably, the described drying-plate surface in step (3) is coated with Oleum Ricini.
Preferably, in described step (5), blown film raw material is that low-density polystyrene and polypropylene are in the ratio of 1:1.5～1:2
Mixed mixture.
Beneficial effect: the present invention improves the toughness of woven bag, i.e. prevents the phenomenon of rupture in subsequent production, makes again in envelope
Will not ftracture during dress cement；Applying Oleum Ricini on drying-plate, Oleum Ricini is smeared flat filament surface, is improve flat filament ductility, convenient
The rolling of flat filament and circle are knitted.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
Embodiment, is expanded on further the present invention.
A kind of cement packing woven bag preparation method, comprises the following steps:
(1) be dried stirring: be 40 by proportioning～50% polypropylene, 20～30% polystyrene, 15～20% molybdenum bisuphide and
