Production method of glass magnesium boards and glass magnesium veneer boards

Abstract

The invention relates to a formula and a preparation method of glass magnesium boards. The glass magnesium board comprises the following components according to a mixing ratio in parts by mass: 50 to 60 parts of light burning powder, 15 to 20 parts of bittern slices, 13 to 16 parts of shell, 8 to 10 parts of bits of wood, 2 to 4 parts of trisodium phosphate and 1 to 2 parts of talcum powder. A production method of the glass magnesium boards comprises the following steps: preparing slurry, forming board blanks, demolding and curing, cutting and drying. The invention also relates to a production method of glass magnesium veneer boards, which comprises a production device of the glass magnesium veneer boards and a manufacturing method of the glass magnesium veneer boards. According to the production method, the shell is used as the raw material for producing the glass magnesium boards, so that the waste is utilized, and the impermeability and the mildew growth resistance of the glass magnesium boards are also improved; the production device of the glass magnesium veneer boards is reasonable in structural design; the production process of the glass magnesium veneer boards is simple and is low in cost; PVC films are adhered to the glass magnesium boards by a thermal bonding method; the adhesion is high; the problems such as buckling deformation can be avoided.

Description

technical field [0001] The invention relates to a production method of a glass magnesium board and a decorative board thereof. Background technique [0002] Due to its low cost, low weight, and corrosion resistance, glass magnesium boards are widely used in construction industries such as wall panels, ceiling panels, fireproof panels, waterproof panels, and packaging boxes. , mildew or rot and other defects. In the present invention, shells are used to replace traditional filling materials of the glass magnesium board, which can significantly prevent the glass magnesium board from returning brine and growing mildew. [0003] Existing glass-magnesium veneer panels generally use special glue for glass-magnesium panels to paste wallpaper on glass-magnesium panels. Glass-magnesium veneer panels produced by this method are prone to aging. After being used for a period of time, or exposed to high-temperature environments, they are prone Warping deformation occurs, and the wallpa...

At present, the development of oysters, clams, razor clams, and sea rainbows in my country is mainly to process their edible parts. While utilizing the edible parts, a large number of shells are discarded as garbage. The residual organic matter in these discarded shells is piled up for a long time Corruption and smelly during the process, endangering the lives of residents and causing serious pollution to the environment
