Foam molding machine screw and barrel with circulating water for cooling, furring, solenoid valve failure as the main things. Each phenomena talked about above will also lead to temperature abuse, so the device is powered on in the process, really should preserve the smooth flow of oil or water cooling, and always verify any attachments are normal.
High Pressure PU Foaming Machine
Foam molding machine is usually observed via the oil temperature and water temperature indicator and pressure indicator on plastic extrusion panel judging the State of devices within the external wall insulation. Equipment factory on polystyrene foam plate screw will not be correctly seated, installed occur collisions, falls, deformed screw to a specific extent, there are burrs, resulting in poor top quality of extruded polystyrene foam boards.
These normally led to instrument in no output state Xia perform, in Asia runaway State (that instrument no output indicates, but temperature shows worth nevertheless slow improved, and has been maintained within a higher temperature points), if occurred this phenomenon, except excluded wind machine, and oil cold, and cooling water, and hot workers instrument, and thermocouple, variables of circumstance zhiwai, requires on screw Rod deformation for confirmed, required Shi grinding screw rod. On account of the rotation of your screw, plastic particles within the barrel deformation and squeeze, produces heat and temperature rise of in some cases greater than plastic particles of plastic required, even right after turning off energy and they’ve not ceased, and beyond the scope of specifications. At this point, in the event the machine cooling method out of balance, for example cooling fan power shortage, damage, causing the barrel temperature control, produces plastic chemical imbalance.
For producers, just understanding how models and foam is just not enough, you also have to know far more about a number of essential technical parameters in foaming machines, to establish whether it meets your production needs.
1) output: output is foam-producing capacity, volume of this content must be slightly higher than their desired foam 20% to be able to leave room for its foam yield shall be calculated on the basis of authorized by the lower bound of, not as an upper limit;
2) capacity: capacity is definitely the total energy, accounted for this parameter on electrical circuit is important for total adaptation;
three) size: this parameter is required for workshop layout preparing elements;
four) bubble size ranges: should normally be controlled in accordance with the product-specific needs for bubble.
Foaming machines 1st appeared in foreign nations, their original models will be the use of high speed rotation from the impeller foam, also called „beating“. Later, as technology advances, foaming machine technologies and continuously enhance, new models emerge, formed different technical systems. Our foam machines in use as early as in the 1950 from the 20th century, nevertheless it is not special foam models, as opposed to employing mortar mixer.
Foaming agent straight in to the concrete or mortar mixer blender, foaming agents and mortar or concrete mix to generate foam. Ahead of and just after within the 1970 in the 20th century, started to possess specific foaming agent, namely, high speed impeller foam machine. Following continuous technological upgrading and replacement, has now developed into a high-pressure inflatable for the primary body from the third generation model, and may essentially meet the needs of foam concrete.
