product description
Fiber cement Board is composed of paper fiber, siliceous lime, slacked lime, quartz powder and adding appropriate reinforced material,processed by pulping、molding、autoclaved curing and drying、sanding etcs procedure to be one kind of new mtaerials with features of light weight、high strength、excellent refractory and heat insulation performance.
This product can be widely used as building interior wall、suspended ceiling and acoustic panel of gyp/theater/meeting room after sawed、drilled、nailed、planed etcs process and calcium silicate board surface decoration processing.Calcium silicate board also can combine other materials and then change into kinds of fireproof、sound insulation 、Energy saving tub surround.
Slurry preparation
1.Put cement, quartz powder, pulp, and other raw materials with water (controlled by Φ4000 backwater tank) in the pump beater. All material will be mix up in here continuously until reach the standard.
2.Transfer slurry to bucket slurry storing pool, and keep the mixing process to keep the consistency. After that, slurry will be pour on the running carpet, dehydrate through the vacuum chamber, compact and roll on the forming roller. The layer of the slurry will keep adding the thickness and dehydration. Thus, basic format of the board formed, called slab.
3.The left over liquid after the dehydration process will be collected and pump back to the mixed water tank for reuse. After the precipitation, sediment will be sent back to the pump beater with raw material for reuse. Mixing water will also sent back for adjust the consistency of the slurry. Clear water will use for washing the running carpet.
4.Detach slab from the forming roller, and longitudinal shearing machine will be used in here to cut both side of the slab.
5.There are two Hydraulic vacuum stackers attached on the three-position hydraulic vacuum loader for attaching a mold to the slab. They move synchronously to finish this cycle.
Step one, stacker one picks a mold from mold trolley. Step two, lifting platform will push those two stackers up and down. Stacker one drops the mold on the steam trolley, and the cutting blade which attached before the stacker two will trim horizontal sides of the slab. Stacker two picks up a slab from the conveyor.
Step three, stacker two puts the slab on the stream trolley, and stacker one goes back to mold trolley for picking the next mold.
6.Waste edge which cut from the slab will be sent back to back material mixer. After mixing, it will be reused.
7.Slab on the steam trolley now will be settled to the steam curing room for mold detachment.
Our company is the first manufacturer in China to develop and produce automatic PVC gypsum ceiling production line. It has fully automatic production line（single-side lamination type and double side lamination type), semi-automatic production line and economic type for customers to choose. As the production line uses modular combination, we can give appropriate solution according to customer requirement and budget.
The production of MgO board adopts the wet plate rolling forming process, where the raw materials are measured and weighed through proportioning, mixed and stirred by a mixer (manually or automatically), and rolling forming. Primary curing, demolding and secondary curing in the curing room. Cutting and sanding, quality inspection and packaging. Complete the entire production system. The products are divided into: regular version of MgO board and MgO sanding board.
The mineral fiber board production line includes raw material mixing system, fourdrinier forming system and vacuum pump system, water cutting system, accelerating conveying system, lifting distribution system, board feeding system, drying system, hot air circulating system, board releasing system, board over-turning system, puttying system, small drying system I, coating system, small drying system II, embossing system, small drying system III, cutting system, dust collecting system, packing stacking system, control system.
Calcium silicate board as a new green environmental building materials except the traditional gypsum plate of features outside, it has superior fire performances and the resistance tide, sound insulation, fireproof waterproof heat insulation,light weight and so on. It also has the advantage of using long life. The new type of board is widely used in the building of ceiling smallpox and wall, family decoration and so on.
