Brakes are used in the manufacture of what is known as polyester porcelain. In the event that a polyester corset is added to the polyester, it will melt in 3 hours or 4 hours. In this case, we use cobalt steel to accelerate the pumice directly on the drying of the material in a quarter horse Well, we will notice that the fluidity is very high, and when pouring it will be cut off, so we will add another material to gain some thickness or thickness. We will use spidage for every kilo of polyester. We will add a kilo of spidage if the designs are beautiful and have many engravings, or if the mold is simple and easy, we will add 2 kilos of spidage to every kilo of polyester, if not. In Spedag You can work with calcium carbonate or hypo, and you will leave a quarter of an hour for the reaction. We will work on a product in which we take 300 grams of the mixture that we made, add 3 grams of hardener to them, and stir well. Then we bring the mold, take part of the mixture, put it on the mold, and leave it until the polyester reaches the precise places that are difficult to reach during the process. To pour The mold is closed with plastic or plastic and we pour the rest of the quantity into the mold and move it in all directions until the mixture reaches all parts of the mold. When we feel the mixture solidifying and we look at the bowl of the basic mixture and notice that it is drying, we close the mold and leave it and it is sealed with a piece of wood greased with an insulating material and it becomes soap Washing up liquid, the seat is closed and the mold is left, and after five minutes it has dried or dried. The total time from the beginning of pouring is approximately equivalent to three hours. To remove the speed, we add more cobalt This is the result after work and the stains are removed while it is still soft after coming out. Then the inspection is done. It is sanded well and then painted. Thank you, Mustafa Khafaji was with you.
