The plastic barrel formed by the production technology is excellent in mechanical property, strong in intensity, thick in wall thickness, high in overpressure resistant intensity, hard to damage, and has excellent antirust anticorrosion function, so the plastic barrel can be repeatedly used in a long time.

Description

A kind of production technology of Plastic Drum

Technical field

The present invention relates to a kind of production technology of Plastic Drum, belong to Plastic Drum manufacturing technology field.

Background technology

Plastic Drum is used for storage and the transport of various liquid, to special dangerous articles package, there is good characteristic, it has the features such as non-friable, non-corrosive, light weight, and oil resistant, performance of being able to bear strong corrosion are good excellent, are used for needing insulation, moistureproof, withstand voltage, erosion resisting dangerous articles package.Plastics blow molding, injection moulding, plastic uptake, the rotational moulding such as material many employings polyethylene, polypropylene, polyester of Plastic Drum form, and are used for industry liquid, the solid articles such as splendid attire chemical industry, agricultural chemicals, medicine, food, five metals electronics, electromechanics.The primary raw material producing Plastic Drum is polyethylene (Polyethylene, PE), and being called for short PE, is the macromolecular organic compound that ethene carries out addition polymerization.Polyethylene is the contact food optimal material of generally acknowledging in the world, and nontoxic, tasteless, odorless, meets packaging for foodstuff hygienic standard.Polyethylene foil, merrily and lightheartedly transparent, have protection against the tide, antioxygen, acidproof, alkaline-resisting, air-tightness general, the performances such as heat sealability is excellent, have the laudatory title of " flowers of plastics ", is maximum, the most important material of plastic wrapping printing consumption.But due to manufacturing process restriction in existing Plastic Drum, such that the bad mechanical property of produced steel drum, intensity are low, thin-walled, compressive resistance are low, the packing container of cracky.

Summary of the invention

The object of the invention is to: for the defect of prior art, propose a kind of production technology of Plastic Drum, with the obtained Plastic Drum satisfactory mechanical property of this technique, intensity is high, wall thickness, compressive resistance are high and the not feature such as cracky, there is the function of good antirust, anti-corrosive simultaneously, can Reusability for a long time.

The technical solution adopted in the present invention is: a kind of production technology of Plastic Drum, comprises the following steps:

Step one, batch mixing: new, feed back and look mother pour in puddle mixer, stir;

Step 2, material loading: note the amount of regulating plate switch size, cleaning magnetic frame, guarantees that hopper material loading is unimpeded;

Step 3, heating: extruder temperature retention time >8 hour, storing machine head insulation >14 hour, inlet temperature <70 DEG C;

Step 4, to extrude: check that whether photoelectric protector work is normal, stop heating during shutdown, and ensure storing machine head chilled(cooling) water supply (CWS), until temperature is down to less than 90 DEG C, can stop supplying water;

Step 5, shaping: when normally producing, button to be got to fully-automatic production;

Step 6, cut bucket: cutter to people's stub bar, must not must not be thrown out bung without care, bucket face needs mowing smooth, touch not oarsman with hand everywhere;

Step 7, sizing: sizing pressure arranges 0.2-0.3MPa, and shaping time is about 15 minutes, guarantees that every batch of barrel-shaped shape is basically identical;

Step 8, punching: use the boring rifle of ∮ 4.2 drill bit to make a call to an aperture in the both sides of bucket;

Step 9, inspection: test according to Plastic Drum inspection procedure, warehousing after passing;

Step 10, warehouse-in.

After adopting technique scheme, beneficial effect of the present invention is: with the obtained Plastic Drum satisfactory mechanical property of this technique, intensity is high, wall thickness, compressive resistance are high and the not feature such as cracky, there is the function of good antirust, anti-corrosive simultaneously, can Reusability for a long time.

Accompanying drawing explanation

Fig. 1 is schematic flow sheet of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is further illustrated.

As seen from Figure 1, a kind of production technology of Plastic Drum, comprises the following steps:

Step one, batch mixing: new, feed back and look mother pour in puddle mixer, stir;

Step 2, material loading: note the amount of regulating plate switch size, cleaning magnetic frame, guarantees that hopper material loading is unimpeded;

Step 3, heating: extruder temperature retention time >8 hour, storing machine head insulation >14 hour, inlet temperature <70 DEG C;

Step 4, to extrude: check that whether photoelectric protector work is normal, stop heating during shutdown, and ensure storing machine head chilled(cooling) water supply (CWS), until temperature is down to less than 90 DEG C, can stop supplying water;

Step 5, shaping: when normally producing, button to be got to fully-automatic production;

Step 6, cut bucket: cutter to people's stub bar, must not must not be thrown out bung without care, bucket face needs mowing smooth, touch not oarsman with hand everywhere;

Step 7, sizing: sizing pressure arranges 0.2-0.3MPa, and shaping time is about 15 minutes, guarantees that every batch of barrel-shaped shape is basically identical;

Step 8, punching: use the boring rifle of ∮ 4.2 drill bit to make a call to an aperture in the both sides of bucket;

Step 9, inspection: test according to Plastic Drum inspection procedure, warehousing after passing;

Step 10, warehouse-in.

Above the specific embodiment of the present invention is described, but the present invention is not limited to above description.For a person skilled in the art, any equal amendment to the technical program and substitute be all within the scope of the invention.Therefore, equalization conversion done without departing from the spirit and scope of the invention and amendment, all should contain within the scope of the invention.
