All the additives are firstly added with a small amount of premixed methyl methacrylate and evenly stirred in a small stirring container, and then poured into a large stirring tank to be evenly mixed.
(2) Degassing filtration
The evenly stirred materials are pumped into a material filling barrel through vacuum negative pressure, and air and impurities in the mixed materials are discharged through a filter screen in the vacuum process (normal temperature; 0.07 MPa), so that the produced product can not be mixed with bubbles and impurities. The defoaming process is closed operation, and the defoaming time is about 30min each time. The filter screen and each filling barrel need to be cleaned according to the product replacement condition.
(3) Glass mold

(4) Adhesive tape, mould preparation, filling and foam pressing
Sealing rings: and sawing off the purchased adhesive tape according to the side length of the die, and then welding the two ends of the adhesive tape into a closed ring by using a welding machine.
Preparing release: and placing adhesive tapes at the edges between the 2 pieces of glass as sealing rings, and locking by using a clamp to form a hollow mold.
Filling materials: and after the mould is inclined, inserting the prying plate into the material filling opening, increasing the opening degree of the material filling opening, injecting the degassed material into the mould by using a PE pipe, clamping and drawing out the PE pipe opening after the mould is filled, and covering the glass.
And (3) bubble pressing: the side of the material filling opening is locked by a clamp, and air in the die is completely pressed out by using an air cylinder.
(5) Water bath and drying room
The filled mold is placed into a stand and is hung into a warm water tank through a crane (normal pressure; 55 ℃), and the temperature is kept for 3 hours, so that the polymerization rate reaches more than about 80%.
The mould after water bath is sent into a drying room (normal pressure; 120 ℃) (hot air circulation blowing) for further polymerization for about 2 hours, so that the polymerization rate of the plate can reach more than 99%.
(6) Cooling, demoulding and sticking paper
And cooling the polymerized glass module to normal temperature by a fan, peeling the glass on two sides for reuse, visually inspecting the upper surface and the lower surface of the acrylic plate, and adhering a bathroom plate forming die according to requirements.
