1. Comparison chart of fire resistance performance (comparison chart of plate surface condition after flame burning at 1000 ℃ for 4 minutes)

Product performance text explanation:

Fire resistance: in order to achieve the same fire resistance requirements, the use of gypsum ceiling is 2 times more thick than Jianyuan board. For example, 8mm Jianyuan board can meet the fire protection requirements, which can only be achieved by two pieces of 12mm gypsum board on both sides. In case of fire, the materials with good fire resistance will not burn and produce suffocating smoke, which can effectively prevent the spread of flame and protect the safety of life and property.

Moisture resistance: the moisture-proof performance of building board determines its service life and engineering effect. In humid climate, gypsum ceiling and mineral wool ceiling are easy to absorb moisture in the air, resulting in material deformation, discoloration and subsidence, affecting the decoration effect. The moisture resistance of Jianyuan ceiling is obviously better than that of other materials, and it has respiratory regulation function to the surrounding environment. The durability of Jianyuan ceiling is 3-5 times of that of common materials, and the project does not need regular renovation and maintenance.

2、 Raw materials comparison between Jianyuan ceiling and mineral wool board

1. The raw materials of Jianyuan ceiling are quartz powder, bentonite, calcium material, reinforced fiber, etc., which are made of light inorganic material plate through pulping, forming, steam curing and surface sanding. It has the characteristics of fire prevention, moisture resistance, high strength, corrosion resistance, no mildew, no bacteria and so on.

2. Mineral wool board is composed of mineral wool, adhesive, pulp and perlite by slag rotating at high temperature, high pressure and high speed, removing impurities and washing.

4、 Performance comparison of health and environmental protection

1. In terms of health and environmental protection, mineral wool board is made of slag and other materials, and its mineral wool dust powder fiber is easy to inhale into human body and is a very high carcinogen;

2. The base material of Jianyuan ceiling is made of silicon material, calcium material and reinforced fiber. The product has no formaldehyde, radiation, bacteria and mildew.

5、 Comparison of scrubbing performance

Explanation: the Jianyuan ceiling can be scrubbed if there is dust or smearing on the board surface. The internal structure of mineral wool board makes the surface of mineral wool board polluted by dust after being used for a long time in dusty environment, and it is not easy to clean and accumulate dust.

6. Introduction of performance data of Jianyuan ceiling products

7、 Comparison of moisture-proof performance

1. Jianyuan ceiling is not easy to change color. The board has the function of breathing. It can adjust the indoor humidity to absorb moisture in wet condition and release moisture in dry condition. The deformation probability of the board is small, and the plate is resistant to subsidence.

2. Mineral wool board: mineral wool board is easy to deform. The color turns yellow with time. Its moisture deflection is higher than the base material calcium silicate board of Jianyuan ceiling.

The reasons for the deformation of mineral wool board are as follows:

1) The distribution of raw materials is uneven and the internal stress structure is uneven;

2) If the self weight is too heavy, the binder will be loose in the case of high humidity, and the bonding effect will be lost, resulting in structural deformation;

3) The back reinforcement layer treatment is not effective or there is no reinforcement layer treatment.

Yingtan is located in the small ecological area of Poyang Lake. The air humidity is high and there is more rain in four seasons, especially in Huangmei. In the wet condition, the mineral wool board will begin to deform and sink in a short period of time. At the same time, affected by the environment, the color tends to turn yellow.

8、 Comparison of fire performance

1. Jianyuan ceiling fire rating is A1

2. Mineral wool board fire rating is generally B grade, the price is expensive, the quality can reach a level.
