High-strength non-burning ceramsite technology has achieved a major breakthrough

2019/5/21

  Non-burning ceramsite is a new variety developed in recent years in China.Although the non-burning ceramsite is a rising star in the ceramsite family,it represents the development direction of ceramsite.Under the policy guidelines of“green mountains and green hills,Jinshan Yinshan,and green mountains and green mountains”,the non-burning ceramsite will gradually develop.This is the general trend.

  The non-burning ceramsite is a ceramsite that does not need to be fired.The ceramsite is granulated by various active solid wastes,cementing materials,admixtures and other auxiliary materials,and then subjected to natural curing(or solar curing,steam curing,Artificial light aggregate made of autoclaved curing.

  Cangzhou Xinye Environmental Engineering Technology Co.,Ltd.is a high-tech enterprise transformed by the scientific research team formed by the research team of Huaye Powder Ball Technology R&D Center on the basis of Cangzhou Huaye Electromechanical Technology Co.,Ltd.

  The company has formed a technical R&D team with complete professional structure,reasonable structure and solid foundation,and possesses a number of patented technologies and scientific and technological achievements.A large number of core technologies with independent intellectual property rights,such as process and product development,engineering consulting and design,equipment manufacturing and automatic control,have been formed.In particular,it has rich technical resources and practical experience in powder processing technology,granulation technology,film coating technology,solid waste treatment and comprehensive utilization technology and non-standard automation control system technology.

  The non-burning ceramsite designed and produced by Zhangzhou Xinye Environmental Engineering Technology Co.,Ltd.has excellent performance.The tested tube has a compressive strength of more than 18Mpa,especially due to the small density of the ceramsite,the internal porosity,uniform morphology and composition,and a certain strength and firmness.

  The burnt-free ceramsite has a relatively high bulk density and is not suitable for the production of ultra-light-free ceramsite;unless special formulations and processes are used.The equipment investment is small,the process is simple,the replacement of varieties is easy,the production cost is low,the solid waste utilization rate is high,and the energy saving trend is met.

  The characteristics of the non-burning ceramsite are as follows:

  (l)High strength,especially suitable for ordinary ceramsite and high-strength ceramsite.By changing the binder,the amount of activator,reasonable formula and curing process,it can produce high-strength non-burning ceramsite,and can be adjusted at will.strength.Therefore,the non-burning process can produce ceramsite products of various strengths.

  (2)Durability is good,and the strength of the late and long-term is increasing.This is the largest and the outstanding advantage of the non-burning ceramsite.After the roasting ceramsite is calcined,the strength will not grow again and will be lost with time.However,after the curing of the ceramsite has reached the technical requirements of the cylinder pressure,the internal hydration reaction has not ended.The strength continues to increase as the hydration reaction continues.Since it takes many years for the active waste residue to complete the hydration reaction;therefore,the strength of the activated waste slag-free ceramsite is slowly and continuously increased within 2-3 years after leaving the factory.When it leaves the factory,its strength only reaches the highest intensity of 75%to 80%,80%-90%after half a year,90%to 95%after one year,and 95%to 98%after three years.strength.Therefore,the non-burning ceramsite has extremely good durability,and the longer the time,the higher the strength.This is incomparable to roasting ceramsite.Therefore,the life of the non-burning ceramic building and engineering is longer.

  (3)The water absorption rate is slightly higher.It is necessary to use technology to treat the non-burning ceramsite produced by conventional techniques.The water absorption rate is slightly higher than that of the roasting ceramsite due to more capillary pores caused by evaporation of water.

  (4)The bulk density is relatively large,and it is not suitable for the production of ultra-light-free ceramsite.Due to the use of a large amount of dense solid waste,the bulk density produced is relatively higher than that of the calcined ceramsite.At the same cylinder strength,its product density is generally above 500 kg/m3.Ultra-light ceramsite below 500kg/m3 is not easy to produce.

  (5)The softening coefficient is higher,and the non-burning ceramsite has a higher softening coefficient.The softening coefficient is generally greater than 0,and the high-strength ceramsite is greater than 0.9,in this respect,it is no less than the calcined ceramsite.

  (6)Acid and alkali corrosion resistance,which can be used in harsh environments.Acid and alkali all have an effect on the waste residue.Therefore,in an acidic or alkaline environment,the strength of the waste ceramsite will increase.This is it and the roasting pottery.The grain is very different.Roasted ceramsite used in acid-alkaline environments will be corroded,while non-burning ceramsite has good acid and alkali corrosion resistance and can be used in these harsh environments.

  (7)Small investment,easy to implement,simple process,low technical difficulty;easy to change varieties,flexible and flexible;low production cost and better efficiency;small workshop area,small mechanical scale;meeting the trend of energy saving,solid waste High utilization rate;no need to use clay to protect cultivated land.
