fiber cement board making machine usage and slurry preparation
Usage:
Gypsum ceiling board is laminated PVC film in front side and aluminum film in back side of paper faced gypsum board. The features are waterproof, moisture proof, flame resistant, thermal insulation,radiation proof, anti-sagging, non-deformed, etc.
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.
Fiber cement exterior wall board introduces the international advance technology to produce the multifunctional molding pressed and flat cement and flat fiber panel,which has good features of the light weight,fireproof,waterproof,mildew proof,mouse proof,termite proof,sound insulation,heat preservation,chemical resistance,high tensile,,long lasting and environment-friendly.
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.
