Plastic chemical barrel is also called plastic chemical barrel, which is developed and blown by scientific formula, with diverse color and beautiful appearance, achieving the packaging index in acid and alkali resistance, corrosion resistance, leakage prevention, no fading, no deformation and so on. It is an ideal choice for the long-distance transportation of packaging materials for chemical products.
HDPE barrel features:
The plastic chemical barrel has the advantages of integral polyethylene (PE) one time forming without joint, impact resistance, aging resistance, light weight, no leakage, acid and alkali resistance, long life, in line with health standards and so on. The performance of the plastic chemical barrel is much better than the traditional glass reinforced plastic container, plastic welding container, steel lined rubber container and so on.
HDPE bucket application:
In a considerable range can replace stainless steel, titanium and other metal products container, is the most ideal chemical liquid corrosion resistant storage and transportation equipment, and cheap and fine.Products are widely used in chemical industry, dye, medicine, pesticide, metallurgy, rare earth, machinery, electronics, environmental protection, textile, food and other industries.
HDPE bucket specifications:
The commonly used plastic chemical barrels specifications have 5 l, 10 l, 16 l, l, 20 l, 25 l, 30 l, l, 50, 60 l, 120 l, 150 l, 120 l, 200 l, etc.
Main process factors affecting plastic blow molding bucket
The main factors affecting production and product quality are temperature, melt, pressure and melt flow velocity.
1, temperature has a significant impact on the performance of plastic extrusion and billet, improve the temperature of the extruder, can reduce the viscosity of the melt, improve the fluidity of the melt, reduce the power consumption of the extrusion, improve the screw speed, without affecting the mixing and plasticizing effect of plastic products to improve the strength of the finish is conducive to improve.
The transparency of the product, the melt temperature is too high, so that the vertical thickness of pictographic billet is uneven under the weight of the billet, increase the shrinkage rate of the product, the high temperature affects the service life of the plastic degradation material products, for the polyethylene bucket, it is true to master the temperature to use the electronic temperature controller, so that the process temperature is stable, and the energy saving is significant.The general setting temperature of feeding every 100-150℃ plasticizing every 200-230℃, compression every 180-200℃.
2. Influence of melt pressure
High melt pressure promotes good plasticization and uniform mixing coloring. Because it is the blend of high-density polyethylene and low-density polyethylene, and the inverse coloring field, the crystal point and cloud pattern on the billet are reduced. Generally, the melt pressure is increased by increasing the screw speed.
3. Solution transportation rate
The larger the solution conveying rate and the higher the extruder output, the higher the screw diameter and the higher the extruder temperature can improve the solution conveying rate.
