(1) Take the magnesium chloride with a relative density greater than 1.2096 into a large cylinder, stir evenly with cold water and dissolve it fully, and pour out the floating foam to obtain the raw material with a relative density of 1.209 6 for use.

    (2) Take magnesium oxide and talc powder over 60 mesh sieves, place them in a container, gradually add chlorine solution, and stir into a paste fabric for use.

    (3) Take the magnesium mesh and talcum powder of 60 mesh sieve, put the wood powder of the 10 mesh sieve into the container, add the solution and mix the 107 glue evenly, make it easy to wipe, and use it as the main material.

    (4) Spread the mold embossment up on the glass of the workbench, evenly brush the fabric on the mold, lay the first layer of glass cloth, and use the plate to loosely press the first layer of Bray cloth on the plate.

The first layer of glass cloth is placed, and the glass cloth and the surface are covered with a brush. The fabric is fully contacted, and the iron frame with iron wire is placed flat on the glass cloth, and then the main material is placed, leveled with a pressure plate, and then flattened with a square trowel to make the thickness uniform, and removed. Iron frame, put a second layer of glass cloth, flatten it with a pressure plate, put the fabric on the plate with a pressure plate, and then put a third layer of glass cloth, smooth with a pressure plate to make the fabric and glass cloth stick, the air temperature is At 25 ° C, it can be used for 24 h. After drying for 3-5 d, it can be sprayed and dried.
