Scatter Coating: Appropriate Materials
Coating is the method in which the thermoplastic resins are applied to the substrate material. Generally used coating methods are: 1. Scatter coating – This method utilizes electronically controlled scattering heads to set down the resin on to the moving fabric. 2. Dry-dot-printing – The resin is printed on to the fabric through engraved roller having micro grooves to retain the resin. 3. Paste coated – the net like structure is formed by heating the resin and then it is laminated on the fabric by applying heat and pressure. 8.1.4 Fusing machinery and equipment In spite of what kind of fusible and equipments are used, fusing is controlled by four processing elements, such as, pressure, temperature, time and cooling and these have to be precisely combined in order to achieve the desired results. 1. Temperature – the temperature of resin should be optimum as high a temperature leads to too viscous resin and too low temperature does not allow the …show more content…
2) Cylinder Heating - The cylinder consists of two parts, the inner cylinder, a stationary assembly in which the heating element are mounted; the outer cylinder, which rotates around the inner cylinder. Pressure Mechanism: Pressure is applied constantly and uniformly right through the process once fed into the machine. Actual pressure is applied at the outlet point where drums put heavy pressure on just heated fusible piece. Time Mechanism: Fusing time is based on the speed of conveyor belt; faster the belt runs, the shorter the time. All machines have speed controller which could be adjusted to give various dwell times in the heated zone. High Frequency

Windshield Replacement Research Paper
614 Words | 3 PagesHow Do I Know I Need Windshield Replacement? You may think a small nick in your windshield doesn 't warrant replacement, but some chips can turn into a big problem down the road. Besides, damage to your windshield can cause glare and other concerns that impede your vision. In addition, many states enforce laws that require windshield glass that is free from blemishes, including nicks or chips.
Spatter Research Paper
443 Words | 2 PagesSpattered blood is a random distribution of bloodstains that vary in size that may be produced by many mechanisms. The size and quantity of spatters produced by a single mechanism vary significantly. The amount of available blood and the amount of force applied to the blood affect the size range of spatters. Spatter is created when sufficient force is available to overcome the surface tension of the blood. The amount of force applied to a source of blood and the size of the resulting spatter vary considerably with gunshot, beating and stabbing events.
Sealcoating Research Paper
507 Words | 3 PagesNeed To Repair Your Asphalt Driveway? How Resurfacing And Sealcoating Differ If your asphalt driveway is faded and showing its age, you may be wondering what you can do to bring it back to life. As long as the base under the driveway is still in good shape, you probably won 't need to tear out the old asphalt and install a new driveway. Depending on the degree of wear and tear, you can have a sealcoat applied or have the asphalt resurfaced.
Summary: Crush The Can Experiment Write-Up
355 Words | 2 PagesThe science behind this is very simple, it involves the behavior of gases. Atoms in a gas is free flowing. They respond and move faster when there is heat, and slower when it is cooler because of a loss of energy. It then changes the pressure of the gas, as the atoms in a certain volume of gas changes. In this experiment, we heated to can with water in it until it was boiling, which

507 Words | 3 PagesThe ultrasound machine has seven different parts, “the first part which is the most important part which is referred to the “eyes and ears of the human body” which is called the transducer probe, which sends and receives sound waves. The second part of the machine is the CPU ( central processing unit) and it is a computer that does all of the calculations and contains the electrical power supplies for itself and the transducer probe. Then the third part of this machine is the transducer pulse control, it changes the amplitude, frequency and duration of the pulses

The Electric Kettle's Impact On Society
884 Words | 4 PagesThis coil has an electrical resistor which resists the flow of electricity, which in effect converts electrical energy into heat as energy goes through the coil. Due to this, the heat energy produced by the resistor heats up the water within the kettle to boiling point. The heating element is controlled by a bimetallic thermostat, which contains a variable resistor inside it. Integrated at the bottom of the kettle, it consists of a disc of two different metals bonded tightly together, curved in a particular direction. As temperature inside the kettle rises, one metal expands faster than the other, set up in a manner
Essay On Welding Safety
998 Words | 4 PagesSafety is the number one consideration when it comes to jobs like welding. Welding can be very hazardous to a welder if he or she is not wearing the proper safety gear or taking the proper safety procedures. When welding a number of things could go wrong from explosions and gases and fumes to electrical shocks, burns and more. This paper will describe welding hazards and procedures that can be taken to avoid them. One of the main safety hazards of welding is fumes and gases.

NOTE: Record the grams of gasoline, kerosene, and lubricating oils that are present in the 50 mL of crude oil. ➢ Select the flask, and choose Heating Mantel option afterward select Max Heat and make sure you record the temperature when you see crude oil begins to boil. ➢ When the crude oil begins to boil, Make sure you turn the temperature down to 60% by decreasing the heating metal two times.
Tuning Forks Lab Report
666 Words | 3 PagesIt was the opposite, with the lowest frequency tuning forks that caused resonance at a higher length. There were many observations, calculations (wavelength, the speed of sound, and percent area from actual speed of sound), a graph comparing the length of two different tubes, and analysis questions. The results of the data showed that the tuning forks with the highest frequency had the shortest tube length. For example, for the 512 Hz of the open-open tube, the distance was .335m and the open-closed tube had .300m. This resulted in the wavelength to be the lowest also. Therefore, the lowest frequencies had the largest tube distance and wavelength.
