Absorptive noise barrier wall:
Using materials capable of absorbing the sound, punching plates and so on, which prevents the sound reflection.
Sound absorption Standards: Noise Reduction Coefficient â?? NRC indicates the amount of noise power absorbed by the noise absorbing barrier wall.
For the absorptive noise barrier wall, the NRC will be within 0.6 to 0.9 range (FHWA highway noise barrier design handbook).
Reflective noise barrier wall:
Using the good noise insulation materials like Polycarbonate panels (PC), Polymethyl methacrylate panels (PMMA), Glass laminate.
Sound reflective Standards: Transmission loss coefficient â?? TL will measure the sound power hit on or transmitted through the walls.
For the reflective noise barrier wall, the TL coefficient is
>25 dB at 500HZ and >30 dB at 1000HZ (refer to KS F4770 standards).

These years, XPE is widely used in market of sports relaxation, such as surfboard, moisture proof mat, shoe material and yoga mat. It also applies to architecture like insulation floor.
Vacuum Skin Packaging for Food is an innovative method through which under the condition of vacuum the product is skin tightly packaged in-between a upper layer of film and a backing tray (or board or film), offering dual functions as skintight visual display package and freshness preserving via vacuum sealing. * Skintight vacuum package can prevent product water element vaporization and shrinkage, so as to preserve its original product tenderness, aroma, color and flavor. * High-barrier vacuum skin packaging film can barrier oxygen and contain bacteria breeding. It can prevent the fat from oxidation and discoloring, so as to achieve a longer shelf life. * After vacuum packaging and freezing storage, the cooked meat can taste more tender and juicy. * It can prevent ice crystal built-up and desiccation due to freezer burn while being refrigerated. * It can do combined package which the consumer can partially open to eat the desired part of the product then return the remained package to refrigerator for later use for more convenience. * Highly clear vacuum skin pack film offers a visual display package which is more attractive and can evoke purchase desire.

After all the filter chamber filled with pulp, pressure filtration process begins, help feed the pulp into pulppressure pump to solidliquid separation. Since the solid particles remain in the filter cloth of the barrier Chamber and the filtrate drainage ditch on the filter cloth along the filter plate is discharged when the filtrate no longer flows, the dehydration process is completed.At this point, you can stop feeding, the head board returned to its original position, the mobile device will filter plates filter plates have been opened. Cake rely on weight loss. This completes the pressure filtration process.

Customer reversed internal and external leakage of the hydraulic directional control valve, causing vibration, AAK new design solved it all at once Stephen is from Hi-Force hydraulic equipment manufacturing company in the UK. In the second half of last year, he was promoted to the purchasing manager of Kuala Lumpur Branch due to his excellent work. Within a week of taking office, he met with complaints. A batch of their hydraulic cylinders were noisy and vibrated seriously during operation. The after-sales engineer failed to solve the problem within 3 days. The user was not satisfied. Stephen was a little worried. Stephen browsed an article of AAK on Google: "change the design of the hydraulic directional control valve, the vibration disappeared, and AAK eliminated the Canadian factory at zero cost", and left a message: how to solve the noise and vibration of the hydraulic cylinder? After reading this message, I roughly judged that either the hydraulic directional control valve used had problems or the original design had hidden dangers. We asked Stephen to provide the hydraulic system schematic diagram and design drawings, and AAK engineer judges that the working principle of the hydraulic cylinder is reasonable, only by checking on site can we find out the source of the vibration, and then no news from Stephen. 2 weeks later, Stephen emailed that according to the last case that AAK solved the vibration of the hydraulic cylinder, they also added a triangular throttling groove to the hydraulic direction control valve, but after installation, the hydraulic cylinder still vibrated. Their engineers said that AAK solution was a lie. I was speechless and didn't want to explain anything, so I ignored him. 3 days later, Stephen emailed us again, and sent a video of the hydraulic cylinder working and asked our help to check. AAK engineers found that the hydraulic cylinder will emit rhythmic noise and vibration whenever the load drops in the actual work, and preliminarily judged that there is a problem with the hydraulic direction control valve. AAK technical team discussed again according to the drawings, the working principle diagram of the hydraulic cylinder and the working video of the hydraulic cylinder, and confirmed that the problem lies in the hydraulic direction control valve. I told him that AAK could redesign the hydraulic directional control valve and asked him to send us samples of the original hydraulic directional control valve. Stephen may have no choice but promised. 5 days later, we received the sample of the original hydraulic directional control valve, which confirmed the judgment of our engineers that the internal leakage and external leakage of the original hydraulic directional control valve was reversed. 1 week later, AAK sent the newly designed external leakage type hydraulic directional control valve. Stephen informed by email that the noise and vibration problems of the hydraulic cylinder had been
HIGINSON company plans to develop a new plunger hydraulic cylinder, which needs to purchase the supporting hydraulic directional control valves. Helen, who had just joined the company, stumbled when purchasing the hydraulic directional control valves. Helen has no hydraulic valve supplier and can only purchase from the original hydraulic valve manufacturer of the company. Half a month later, the engineer and technician of the company installed the hydraulic directional control valves purchased by Helen for commissioning, and the plunger hydraulic cylinder dropped intermittently with vibration and noise. The technician pointed out that the hydraulic directional control valves needed to be replaced. Helen contacted the original manufacturer of hydraulic directional control valve. Per the manufacturer, the delivered hydraulic directional control valves met the requirements of Helen's parameters, and the accuracy also fully met the standard. As a novice, Helen was helpless, and the technician did not specifically say why to replace the hydraulic direction control valves. She tried to contact the new hydraulic directional control valve manufacturer to solve the problem. Helen left a message on AAK website: why is the plunger hydraulic cylinder equipped with hydraulic directional control valve noisy? At this moment, we can't tell the reason. After communicating with Helen, I learned the process of purchasing this hydraulic directional control valve and the judgment of technician in their company. AAK engineers are not 100% sure that where the problem is according to the hydraulic directional control valve drawings sent by Helen, the shipment sample of the original manufacturer and the video of their technician's machine test. We are thinking if Helen, as a novice, has mistaken the type of hydraulic directional control valve? The hydraulic directional control valves can be divided into internal leakage type and external leakage type. Combined with the working conditions, this plunger hydraulic cylinder just reverses the oil outlet chamber, and the back pressure is high. If the internal leakage hydraulic directional control valve is used, there will be abnormal phenomena such as vibration or noise. We told Helen our thinking. She really did not note to the original manufacturer that the hydraulic directional control valve is internal leakage or external leakage. I told her that AAK has ready-made samples of the external leakage hydraulic directional control valve. It is recommended to test the machine with AAK hydraulic directional control valve to see if there is still vibration or abnormal noise. A week later, Helen sent an email saying that AAK hydraulic directional control valve was installed and there was no abnormality in the test run.
