Foaming machine in daily life

Although we do not see the appearance of foaming machines in our daily lives, this does not mean that we do not touch the shadow of any foaming machines. Because of its superior thermal insulation performance and energy-saving performance, it is widely used.

China is the world’s largest refrigerator producer, inseparable from the development of rigid bubble foaming machines; the rapid development of polyurethane foam can not be developed without the development of foaming machines; the transportation of insulating materials; the development of the automotive industry needs to be written in polyurethane materials; even clothing and Daily necessities are inseparable from the derivatives of a foaming machine series.

Our life cannot develop a foaming machines, which is the source of foaming machine industry development.

Foaming machine itself is not a vacuum bubble output, it is introduced in the air blowing agent, dispersed in aqueous solution, liquid-air interface is as large as possible, so that the surfactant foaming agent on the liquid film surface and the surrounding air A double layer is formed in the air bubble. Foaming machine is a device that can make foaming agent and a certain concentration of aqueous solution into foam. It is actually a dispenser. Its essence is to introduce air into the foaming agent aqueous solution. Its core is the introduction of air into the aqueous solution in the best way.

Pre-expander machine is also equivalent to foam making machine. It is a bubble formed by a mixture of blowing agent water and air. Foam concrete is the main body of the foam. The foam molding machine is the key equipment and main engine for producing foam concrete. Without it, there will be no foam concrete.

EPS Block Molding Machine Cut Off Operation

When the cold bending machine presses the running command, EPS Block Molding Machine the cold bending forming unit main motor first drives the cold bending roller to rotate at a certain speed, this rotation speed mainly by the cold forming of the shelf forming process, the mechanism speed ratio, the cold rolling roll structure size, the hydraulic Shear shear and the unit set the operating speed and other parameters of the decision.

When the shape of the cold-formed components through the transmission track hole position detection photoelectric switch position, send off the power signal to the hole number counter to count, when the hole number reaches the set value when the position detection signal, the rotary encoder to a certain Distance detection and to provide a certain number of pulses to the PLC, PLC to detect the number of pulses, EPS Block Molding Machine the main motor to send a deceleration, stop the command, while the main motor to the hydraulic sequence control valve after the cut off control command to drive the hydraulic shear to cut off the operation.

According to the above principles, the design of the cold-bending unit can achieve precision: hole error does not exceed ± 0.3mm, hole cumulative error of more than ± 0.5mm, single product length control accuracy is generally controlled about 0.5mm, EPS Block Molding Machine to a certain extent to meet the shelf Design Accuracy of Steel Structure Assembly.

The Dynamic Matching Problem between the System and the Load in the Servo System of the Pre – punching Unit with the Load Run.

Cold bending machine rolling stability problems, the production of materials often encountered in the raceway in the left and right side of the problem, in fact, EPS Block Molding Machine a single group of rollers by the asymmetry, the left side of the force, the material to the right side of the pendulum; , EPS Block Molding Machine The material to the left side of the pendulum. The solution is:

The neutral layer of the deformation area is accurate, the material used in the deformation area is accurate and the roller processing symmetry is good.

No deformation of the region as far as possible without pressure (such as the bottom of the slide), the assembly of the upper and lower rollers when the regional gap to maintain consistency.

Material bite before, should be based on the previous road rolling state, EPS Block Molding Machine set the guide ramp, before the steady pressure, the material in the roll smooth smooth.

Cold bending machine production in the bending of the problem, mainly caused by uneven force, about force imbalance, left and right bending, up and down the force imbalance, resulting in distortion.

EPS Recycling System

Description of EPS recycling system:
Expanded Polystyrene is completely recyclable. While limited end-use markets and economies of scale make recycling in this country a difficult operation, there are a variety of uses recycled EPS can be put to:
1. EPS can be granulated and mixed in with virgin material to make new products – some grades of EPS insulation board and block moulded EPS can incorporate recycled content.
2. EPS granulate can also be used on its own and mixed in with plaster or concrete to make a lightweight building material.
3. Used EPS can be ground and mixed with soil and compost to promote aeration.  Studies confirm that plant growth is enhanced with this aeration.
4. EPS can also be melted and converted to General Purpose Polystyrene (GPPS) pellets and used to manufacture simple polystyrene products such as coat hangers, video cassette and cd casings, stationery items and plant pots. 

Waster Reduction Options for EPS:
There are four main waste reduction options for EPS packaging:
1. Reduce – refers to the reduction of natural resources used. By optimising pack design, moulders can reduce EPS usage, thus reducing environmental burden and cost.
2. Reuse – EPS packaging can be re-used as multi-trip packaging, e.g. for the internal transport of partially assembled goods. Another simple re-use of the packaging is to grind it and use it as soil conditioner to improve drainage and aeration. EPS seed and pot-holding trays are often re-used in this way at garden centres.
3. Recycle – is the reprocessing of used EPS packaging to make a new material such as hardwood replacement for making garden furniture, slate replacement for roofing tiles and new plastics items such as coat hangers, CD and video cases.
4. Recover – EPS has a very high calorific value, higher than that of coal, and can be safely burnt within energy recovery units, or incinerators, without giving off toxic or environmentally damaging fumes
