Description
Technical field
Foam maker and foam performance that the utility model belongs to the blowing agent that is specially adapted for producing foam concrete detect and evaluating apparatus, relate to a kind of blowing agent foam maker and Performance Detection and evaluating apparatus.The foam that is applicable to blowing agent takes place and the foam performance detection.
Background technology
High-performance quick generator for foam is a kind of mechanical device of producing the required foams of construction material such as preparation foam concrete block or foam concrete insulating, after the foam that high-performance quick generator for foam is made and the cement slurry of cement slurry or spikes such as concrete mortar or mixed powder coal ash evenly stir, make foamed cement slurry or foam concrete mortar or foam pulverized fuel ash cement slurry, its moulding by casting is promptly obtained foam concrete block or foam concrete insulating.Above-mentioned building materials quality quality depends on all multifactor, comprises the density of foam concrete, the performance of blowing agent, the uniformity of foam slurry, the factors such as compatibility of foam aperture and foam and cement slurry.And the performance and the foaming mode of the uniformity of foam slurry and foam aperture size and foam maker have direct relation, and the quality of foam concrete performance is played conclusive effect.
The present stage development comparatively production method of ripe cellular concrete product mainly contains two kinds.First method is a high-speed mixing method, and this method can be divided into two kinds of foaming modes again: a kind of mode is that foaming agent solution is poured in the homogenizer, and the adding concrete fully stirred after the high-speed stirred expanding foam solution was produced foam then.This method is easy to operate, and favorable reproducibility can reflect the foamability and the foam stability of blowing agent more exactly, is the method for testing that domestic system bubble technology generally adopts; But the shortcoming of a maximum of this method: fully need foam is transferred in the cement slurry after the foaming, in this process, may cause that the fragmentation of part foam and foam size to inhomogeneous variation, finally cause the performance of cellular concrete product to reduce.Another kind of mode be first with foaming agent solution with after concrete mortar mixes, foam with homogenizer again, directly make gas-liquid-solid foam concrete slurry; This method is compared with first kind of foaming mode, though can improve production efficiency to a certain extent, cause the pore-size distribution of cellular concrete product to broaden, have influence on the intensity of foamed concrete material, and blowing agent can not fully be foamed, reduced its utilization rate.The another kind of method that is used to make cellular concrete product is an air-compressing, this method is that foaming agent solution is pressurized to certain pressure, mix with pattern and pressure-air at foam chamber mesohigh water then, directly be added in the concrete mortar, make concrete product; Perhaps add to concrete mortar again after with foaming agent solution and compressed air mixed foaming, make the foam concrete slurry at last by blowing agent.Compare with high-speed mixing method, pneumatic plant is than homogenizer complexity, though system bubble technology is advanced, foaming efficient is higher, and the quality of foam is better relatively, but its foaming machine is expensive, make the cellular concrete product cost improve greatly, be unfavorable for large-scale production.
The application difference of foam, also inequality to the requirement of foaming properties, but majority is with the foam performance of foam and the foam stability index as the blowing agent performance in the practical application.Continuous development along with monitoring means, the researcher has developed various foaming properties evaluation methods both at home and abroad, but these methods mostly are independent development, lack corresponding country and industry standard, the comparativity of foaming substance detection and evaluation result is poor, demands the accurate more and higher Comprehensive Assessment Technology of standardized degree of development and operation urgently.
