1. Advantages of fly ash brick machine equipment:
1. Fly ashHigh blending ratio, Utilize coal ash waste slag waste, save cost.
2. Fly ash brick machine pressure forming, finished brickhigh strength, neat appearance, good quality, used in construction.
3, haveA variety of fly ash brick making technology, can be selected in combination with the proportion of fly ash raw materials.
4. Can be combined with customer needs,tailor-madeFly ash brick production line equipment.
2. Display of finished bricks of steam-cured fly ash bricks:Annual outputThere are 30 million, 40 million, 60 million, 100 million and 120 million bricks, and the production line can be configured according to your needs.
3. The forming principle of fly ash brick making:
The steam-cured fly ash brick mainly relies on the effective CaO in the quicklime and the SiO2 in the fly ash to start a thermal synthesis reaction under the condition of saturated steam (above 174.5°C) with a pressure above 0.8Mpa. Various types of silicate gelling substances are produced, most of which are calcium silicate hydrate and a small amount of magnesium silicate, etc., which are firmly cemented with aggregate fly ash to form a certain structural strength. Its reaction process:
CaO+H2O—Ca(OH)2+15.5 kcal (mixed with body expansion)
Ca(OH) 2+ SiO2+(n-1)H2O Saturated steam at 174.5°C CaO*SiO2*nH2O (calcium silicate)
