Abstract
The improved process of producing plastic bag for packing welding rod includes the following steps: mixing high density polyethylene resin and low density polyethylene resin in the weight ratio of 65-75 % to 25-35 % in mixing apparatus, heating to plasticize in an extruder, blowing up to form film in a mold head, cooling with a blower, winding, printing in a marking machine, and making bag in a plastic bag making machine. The plastic bag for packing welding rod has the following advantages: thin thickness, high mechanical strength, low cost, high heat resistance and capacity of increasing the storing period of welding rod.
Description
Technical field
The present invention is a kind of improved production technique of poly bag for packing welding rods.
Background technology
The plastic bag used for packing welding rods of commonly using has soft PVC plastic bag, LDPE (Low-density polyethylene plastics) bag and high-density polyethylene plastics bag.By the plastic bag used for packing welding rods that polyvinylchloride is made, poor heat stability is subjected to can cause different degradeds after the effect of light and heat, and sinter point is low, become fragile under the low temperature, long-time after, the film embrittlement, this plastic bag used for packing welding rods thickness is thicker, the cost height, the embrittlement that hardens winter, easily crack, summer is deliquescing greatly then, the difficult encapsulation of welding rod; Also have a kind of volatile flavor, it is healthy to influence the workman, and physical property is also relatively poor; The packing welding rods plastic bag mechanical strength of being made by low density polyethylene (LDPE) is low, every moist, gas barrier properties is relatively poor, welding rod moisture-sensitive, Keeping life are short, the manufacturing cost height; The plastic bag used for packing welding rods that high density polyethylene (HDPE) is made. because its puncture resistance is relatively poor, welding rod industry is not all adopted.
Summary of the invention
The objective of the invention is provides a kind of manufacture craft of improved plastic bag used for packing welding rods in order to overcome above-mentioned defective.
Technical scheme of the present invention is: a kind of manufacture craft of plastic bag used for packing welding rods, adopt high-density polyethylene resin and linear low density polyethylene resin mixed material to make a kind of method for making of improved plastic bag used for packing welding rods, it is characterized in that: use the high-density polyethylene resin weight ratio at 65-75%, the weight ratio of linear low density polyethylene resin is at 35-26%, mix to drop into the extruder plasticizing of heating, by die head with the moulding of upper blowing method inflation, through blower cools, batch, seal section, bag, seal.
Technological process of the present invention is as follows: after high-density polyethylene resin and property ldpe resin are pressed 65-75% and mixed in mixing equipment than the part by weight of 35-25%, drop into the extruder plasticizing of heating, by die head upper blowing method inflation moulding, system through blower cools, after batching, batching hopes the material film print on marking machine again, then, making bag on the plastic bag machine, sealing, promptly make the plastic bag used for packing welding rods finished product by the calipers process.
By above technical scheme as can be known, the present invention has the following advantages: 1, plastic bag thin thickness, 2, mechanical strength is good.3, breakage rate is low, and 4, cheap, 5, high temperature resistant, aging, do not ftracture 6, welding rod is not subject to stretch tight, and prolonged the welding rod Keeping life.
The specific embodiment
Embodiment: a kind of manufacture craft of improved plastic bag used for packing welding rods, after high-density polyethylene resin and property ldpe resin pressed 65-75% and mix in mixing equipment than the part by weight of 35-25%, drop into the extruder plasticizing of heating, by die head upper blowing method inflation moulding, system through blower cools, after batching, batching hopes the material film print on marking machine again, then, making bag on the plastic bag machine, sealing, promptly make the plastic bag used for packing welding rods finished product by the calipers process.
