When carrying out construction and repair work polyurethane foamactivelyused to fill various cracks, gaps and seams.
But this is not the only area of its application.
On the eve of the New Year holidays, polyurethane foam, eg, can also be used to create Christmas tree decorations and various crafts.
Due to its properties enough quickly solidify and hold its shape, from the foam are obtained lightweight but durable workpieces.
For the manufacture of Christmas tree decorations most often required balls.
Make themfrom polyurethane foam with your own hands simply and easily. How? Consider below.
We begin the process of making balls with preparing the material.
For this we fill with polyurethane foam to the brim Plastic container and leave to freeze.
Important! For foam to solidify, moisture from the atmospheric air is needed, otherwise the foam will simply remain viscous.
Getting a good workpiece just by filling a balloon or plastic bag with foam will not work.
Then we proceed to the manufacture of the simplest device.
Using a grinder cut off from a tin can on both sides of the edge.
Important! The main condition when choosing a tin can is its rigidity. If the walls of the can are soft, it will be difficult to make a ball.
After complete curing of the polyurethane foam we start making the ball.
To start cut out a blank in the form of a cylinder from the foamwhile firmly turning the tin can clockwise.
Then turn the foam blank perpendicular to the tin can and cut off extra part.
It turns out a kind of square of polyurethane foam.
Then, turning the workpiece at different angles, cut off the excess parts of the foam with a tin can.
The result is an excellent blank in the form of a ball, which can be used to make Christmas toys and crafts.
