Epo foam what is it

Air Force's primary Close Air Support aircraft. It's the highest-performance hog model yet, and is also The E-flite Night Timber X 1. The EasyStar is for a long time the perfect model to get started as an RC The EasyStar is for a long time the perfect model to get started as an RC pilot.

You have to assemble the model and you My wishlists. Menu Planes. Drive Electric Nitro Two-stroke. Bikes Race bikes Road bikes Vintage bikes. Wherein, described coating comprises following component by weight ratio:. For achieving the above object, the present invention also provides a kind of preparation method of EPO bubbles model water-borne coatings, comprises the following steps:. According to the weight percent formula of setting, get raw material ready;.

Filling after stirring, make EPO bubbles model water-borne coatings. The invention has the beneficial effects as follows: compared with prior art, EPO bubbles model water-borne coatings provided by the invention, the hydrate colour pigment for the model airplane external coating that is specifically designed to EPO material of children's research and development, by a kind of water-borne coatings of modern technologies produced with combination by water, mill base, emulsion and multiple auxiliary agent, the good characteristics with zero VOC discharge, high glossiness and higher surface adhesion force, also can be used for the external coating of other various materials.

This aqueous colorful pigment is single-component coating, need not separately with other auxiliary reagents, just can reach good landscaping effect, proportioning and constituent optimization because of its science, can be at EPO, the various material surfaces such as EPP are scribbled arbitrarily, sticking power is good, glossiness is high, the volatilization of toxicological harmless material, fragrant odour, bright in luster, tack-free after surface drying, by immersion, hand-wash and can remove, simple and easy to use, be applicable to very much more than 6 years old art designing's artistic ability of children and exploitation and the exercise of intelligence, also can be used as the sole pigment that the fine arts are raw and artist creates, there are wide market outlook.

In order more clearly to explain the present invention, below in conjunction with accompanying drawing, the present invention is further described. Refer to Fig. Step , gets raw material ready according to the weight percent formula of setting;. Step , filling after stirring, make EPO bubbles model water-borne coatings. Situation compared to prior art, the EPO bubbles model water-borne coatings that the present invention makes by aforesaid method, the hydrate colour pigment for the model airplane external coating that is specifically designed to EPO material of children's research and development, by a kind of water-borne coatings of modern technologies produced with combination by water, mill base, emulsion and multiple auxiliary agent, the good characteristics with zero VOC discharge, high glossiness and higher surface adhesion force, also can be used for the external coating of other various materials.

Embodiment 1, and EPO bubbles model water-borne coatings comprises following component by weight ratio:. Embodiment 2, and EPO bubbles model water-borne coatings comprises following component by weight ratio:. Embodiment 3, and EPO bubbles model water-borne coatings comprises following component by weight ratio:. The present invention for the method for drafting of EPO model plane is: first with pen, on EPO foam, makes a draft, then, with the application of foam paint, after surface drying, is coated with again one deck, and, need to be dried more than 6 hours.

Water-borne coatings of the present invention has carried out experiment through research technique and has detected, and examining report partial content is taken passages as follows:.

Trainers are designed to have a gentle stall, advanced aircraft are tuned to provide high performance with reasonable flight times, and aircraft intended to attract a general audience are balanced with a range of pilot-friendly characteristics.

This conversion is a very labor-intensive process which can take two to four months, involving scientific methods to visualize how the molds will perform during both the injection and assembly phases. The major parts themselves are divided into sub-structures, which are assembled like a puzzle. Innovations within this mold design phase have contributed to the smooth surface quality seen on many modern foam RC aircraft.

In fact, one of our typical midsize aircraft will utilize parts composed of many materials including foam, fiberglass, carbon fiber, plastic, FRP, HDPE, plywood, brass, nylon, steel, and aluminum.

A finished model like the Freewing A contains over parts. A 5-ton CNC machine mills a fuselage mold over several days. The process of milling the molds alone requires hundreds of hours. Larger fuselage and wing molds can weigh several hundred pounds and are transported using forklifts, and even smaller plastic molds require a heavy duty gantry to move them into the injection machines.

ISO standards are maintained at all our partner factories to ensure quality, and our Motion RC team personally inspects each factory at regular intervals. Once finished, the set of molds are transported to our factories to begin their work.

The foam molds are comprised of two halves which are designed to fit together. Liquid foam is injected at a predetermined temperature and pressure into the cavities between the two mold halves. After a set time, the mold halves are hydraulically separated, and a worker enters the machine to remove each part by hand before preparing the mold to cycle again.

Much like a recipe, the ingredients are tested until the perfect combination is found. There are also different grades of EPO foam, each with different properties.

Sometimes a single aircraft will use two or even three grades of foam. For example, our Freewing A uses heavier but stronger foam for its wing roots, and lighter foam for its fuselage where flight loads are comparatively lower.

With the molds completed and tested, the final production phase can begin. First, production teams are trained to produce the new aircraft, with direct input from the engineering team to ensure every detail is reviewed carefully. Materials are ordered from a series of suppliers, initial production testing begins, and flight testing continues.

Serial production begins with preparing the molded foam and molded plastic parts, painting all external parts, then constructing, installing, and testing the electronics including servos, ESCs, motors, electric retracts, and LED lighting. Independent QC teams scrutinize each stage, with specialists in electronics, molding, painting chemistry, and packaging. To protect the foam surface, every workstation is padded, and each time a foam part is moved to the next station it is rewrapped in foam and transitted on a foam padded rolling shelf.

Workstations are rewrapped in fresh foam on a regular basis to keep them clean. Over people will touch an aircraft through the production process before it reaches a customer, so protective measures are important.
