Process plan and investment estimates

First, the gypsum block
Gypsum block is building gypsum as the main raw material, by adding water, casting and drying and made of block light construction gypsum products. In the production according to the performance requirements can also be added to light aggregate, fiber reinforced materials, foaming agents and other auxiliary materials. Sometimes some high strength gypsum (α half water gypsum) can be used instead of building plaster.
The shape of the gypsum block is a flat rectangular parallelepiped, and the dowels and grooves are provided in the vertical and horizontal sides. In addition, gypsum block can be divided into solid and hollow block two categories.
According to the draft international standards, gypsum block length should not be greater than 700mm, block height should meet the block surface area of not less than 0.25m2, thickness of 60 ~ 150mm. Recommended block size: length of 666mm, height of 500mm, thickness of 60mm, 70mm, 80mm and 100mm, that is, three blocks composed of 1m2 wall.
Gypsum block is mainly used for frame structure and other structural construction of non-load-bearing walls, generally used as a partition wall. If the appropriate fixed and support structure, the wall can also withstand heavier loads (such as hanging cabinets, water heaters, bathroom appliances, etc.). Dust-proof blocks that incorporate special admixtures can be used in bathrooms, bathrooms, etc. are not persistent wet conditions.
Gypsum block with light weight, size, fire, earthquake, thermal insulation, adjust the indoor dry and dry, excellent processing performance and ease of construction, etc., is the focus of the national application of environmental protection, energy-saving green products.

Unique advantages

Customization process

Process:
The calcined natural gypsum or chemical gypsum powder is first sent by the pneumatic pump or bucket elevator and other mechanical equipment into the plaster storage warehouse (silo with vacuum facilities, material level automatic transmission device and broken arch device, etc. ), And then into the conveyor and feeding equipment. After the metering system is measured by the electronic weighing scale through the pneumatic discharge valve into the mixer. The production water is measured by the adjustable water metering device of the batching system and also into the mixer through the pneumatic discharge valve. If necessary, add an appropriate amount of coagulant to the mixer.
The components were homogeneously mixed by means of a strong agitation of the stirrer in a mixer, and the slurry was automatically poured into the mold cavities of the molding machine by a hydraulic reversing device. At a suitable stage of the solidification of the slurry, the hydroforming scraper mounted above the mold cavity is driven to move back and forth to scrap the upper part of the block. The central hydraulic station then drives the jacking system of the forming machine to eject the entire gypsum block from the mold. At this time in the molding machine above the pneumatic telescopic fixture will be the whole row of sandwich, lift, remove, put on the stack or car. And then transported by the forklift to the natural drying site dry, or by the car will be stacked into the tunnel kiln for artificial drying. Dry finished gypsum block after passing the inspection, you can transport, packaging for finished product storage or loading Sinotrans.
