Cement foam insulation board production line

    Foam floor slab is an A-class non-combustible inorganic heat preservation material, which has the good fire performance, thermostability at 1200 degrees for three hours, still maintains integrity, because the closed foam rate > 95%, thus it has good insulation performance. The product, with light bulk density, big volume,and the density is about 250 kg/cubic meters. Because of the numerous independent bubble, so the sound-absorbing effect is more effetient than the common concrete about five times, and the sound insulation coefficient is greater than 45 dB. The board has passed the anti-fatigue vibration (1.5 million times) experiment by the national testing center. The integrity of this plate and steel structure by welding, can resist the 9 magnitude quake. The resistance of bending load is 3 times of its self weight (national standard is 1.5 times).The compressive strength is more than 5 mpa (national standards for 3.5mpa). The hanging force is more than1500N (national standards for 1000N), With the characteristics of avirulent and harmless, environmental protection and energy saving, the life of Foam floor slab is more than 50 years, same with the building.

Cement foam insulation board production line flow chart

    Our company provided the automatic cement foam insulation board production line to Shaoxing Zhongji Waterproof Material Co., LTD in Zhejiang province since 2005, now nine sets of automatic production lines in different types continuously have been manufactured and saled, and the production process is generally:put the water and fiber into the stirred tank, and then cement, fly ash and intensifier, every 5 seconds add early strength agent, so a mixed timekeeping begins, after 20 seconds add the pearl powder, while the first mix process is over, add the hydrogen peroxide. And the second mixed timekeeping starts. (the 1^st mixture keeps 100 seconds, the 2^nd mixture keeps 20 seconds, and discharging keeps 25 seconds), the whole production time is 4 minutes. And the foaming time from the start of the discharging is about 30 minutes,and we can tear the mold open. The foaming volume is 1030 * 1030 * 360 mm, so the production is about 12 cubic meters by the dual machines every hour.

The advantages as follows:

1、 Cement, fly ash, and vitrified micro bubbles are mixed together in pulpous state, with the characteristics of spontaneous bubble, light density, and fire prevention performance. The material is the national recommended new type of building materials.

2、 Raw material is sent to the store silo by the pneumatic conveying system, with the excellent performance of fast feeding process, environmental protection, no residue and low consumption.

3、 Intelligent pneumatic conveying equipment is the patent of our company, adopting PLC and touch screen control model, and this device perfectly combines automatic measureing and pneumatic conveying technology together, and the whole transportation happens in the sealed pipeline,which can be cleaned by the equipment itself. The transportantion of the stuff is conveyed very clearly. To prevent demaging the pipe in the course of transmission, our company applies ceramic technology in the elbow, so the wear-resisting effect is significantly enhanced. Comparing with the traditional batching scale and elevator, the piping layout is quite flexible, and no position limitations.

4、 Through the pneumatic tee valve in the piping installation, the pneumatic conveying system can realize the point-to-multipoint transportation. In the illustration there is a measuring system, realizing one pipe conveying into 2 agitated reactors.

5、The additives can be measured pricisely, avoiding the artificial errors caused by the manual feeding.

6、 Liquid applies automatic feeding, heat preservation and quantitatively discharging into the agitated reactors.

7、 Powder and fluid are stirred well, fast, and discharging thoroughly, keeping clean in the kettle. In the illustration, feeding, bacthing, transportation, mixing, and discharging, are finished in four minutes completely.
