Thermoplastic Drive Through MarkingsThermoplastic Drive Through Markings

thermoplastic drive thru markings

Drive-thru markings company near me is a long-lasting road marking substance, commonly used for parking lots and streets. It is made up of a plasticizer, binder and pigment. The dry thermoplastic material is heated in a preheater to a high temperature, and agitated until it becomes a homogeneous liquid. The markings are then transferred to an application vehicle where they are applied to the surface of the roadway.

The benefits of thermoplastic road markings are numerous. These markings are more durable than traditional paint, and can withstand heavy traffic, weather, chemical exposure, impacts and deicing chemicals. In addition to their durability, thermoplastics are highly reflective and can be easily seen in all light conditions, including at night.

Precision and Durability: The Benefits of Thermoplastic Drive-Thru Markings

One common use of thermoplastics is to create rumble strips, which provide drivers with a physical feedback while driving, helping them maintain control. Thermoplastics can also be built up to varying thicknesses, which allows them to be used for marking curves, acceleration and deceleration lanes, and other practical applications.

Another benefit of thermoplastic is that it can be used to mark a variety of things on roads, cycle routes and footpaths, including parking bays, speed limit arrows, give way symbols, and letters and numbers. Unlike regular paint, these markings are supplied as pre-formed shapes and can be laid on the ground without the need for stencils or specialized equipment. They are ready for traffic in a matter of minutes and last up to 7-10 times longer than paint.

Heat Treatment Services For Welding MetalsHeat Treatment Services For Welding Metals

When weld heat treatment services it is important that the materials are heated before and after the welding process to slow the cooling rate. This helps to maintain the integrity of the parent material and the weld. There are a number of heat treatment services that can be performed during or after the welding process including Pre Heating, Post Weld Heat Treatment and Tempering.

What are heat treatment services?

Pre Heating is a thermal treatment that can be applied before welding to raise the temperature of the parent material and deposited weld metal in order to retard the cooling rate and prevent formation of detrimental phases such as hydrogen embrittlement and cracking of the weld interface. Pre Heating can be achieved using oxy-gas flames, electric blankets, induction heating or other methods. It is important that the heating is uniform around the joint area. Intense non-uniform heating will cause higher residual stresses, distortion and metallurgical changes in the base material.

Post Weld Heat Treatment (PWHT) is a thermal process that is used to relieve the residual stresses introduced to the base and weld metals through forging, cold working, welding and other manufacturing processes. It is also a critical step in the prevention of Stress Corrosion Cracking (SCC). PWHT is achieved by heating the material uniformly to a temperature below its lower critical transformation temperature, holding it at this temperature for a period of time and then slowly cooling back to ambient temperatures.

PWHT should be done in accordance with applicable codes and standards. It should also be based on the expected service conditions and the likely mechanisms for failure of the welds.
