How many grades are China's current standard insulation materials divided into? How effective is the insulation material like extruded board?
Class A (non-combustible), Class B1 (flame retardant), Class B2 (flammable) and Class B3 (flammable) are now generally used in the market to require Class A, and the internal insulation of external walls is at least Class B1.
XPS thermal insulation board is an extruded polystyrene thermal insulation board, which is made of polystyrene resin as raw material plus other raw materials and poly inclusions. It is heated and mixed while injecting catalysts, and then extruded and molded. The rigid foam plastic board. Its scientific name is extruded polystyrene foam (XPS) for heat insulation. XPS has a perfect closed-cell honeycomb structure. This structure allows XPS board to have extremely low water absorption (almost no Water absorption), low thermal conductivity, high compression resistance, aging resistance (almost no aging decomposition phenomenon in normal use).
Advantages of XPS board exterior wall insulation system:
It is suitable for building roof insulation, steel structure roofing, building wall insulation, building ground moisturizing, square ground, ground frost heave control, central air-conditioning ventilation ducts, airport runway insulation, high-speed railway subgrades, etc.
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.
