Question:

Does the building plastic template use it?

Does the building plastic template use it? How's the effect? Can I use 30 to 50 times? Can the fire protection requirements of the steel plate on the cast-in-place plate be achieved?

Answer:

Plastic template this line, and now China is not perfect, may reach less than 30-50 this requirement, but better than the wood template, fire requirements should be able to achieve.

The reason why the use of the template is to use the template template is the accuracy of the template, that is, after the mold can be set to ensure that the finished product finished shape regular, flush. While the plastic film version is not damaged, the completion can achieve this requirement. But the crux of the problem is that the biggest weakness of the plastic film is too brittle. Those who have done the work know that when the demolition of the template, the workers removed the template directly down to throw. And this throw to lead to the plastic film version of the broken, it is very difficult to film in the film. This is also the reason why the plastic film from the interview more than 10 years can not always develop the root causes. And then plastic film board in the mold when it is very strenuous, must drill with a drill, or can not die, not convenient construction. This is also a plastic film version can not become a mainstream template and a fatal weakness. The third weakness is its flammability. Construction site of the steel connections are required welding, welding flowers gradually to the plastic film board, at least in its surface to form a deep pit (or even lead to fire), a direct impact on the finished product surface finish and flatness.
