Raw intensity affect product quality

To improve the strength and quality of the unburned brick making machine need to increase the proportion of binder and enhancer, it can greatly increase the cost of such products. Therefore, some companies to reduce the binder and the ratio of the reinforcing material, the strength and quality of the product also greatly reduces. Many have claimed, this equipment production pastes without steam curing, not knowing the production and the unburned brick eliminating the need for the autoclave steam curing process, which lost more than 10 atmospheric pressure conservation of this critical link. This caused a congenital deficiency of unburned brick, it is difficult to meet the relevant quality requirements.
According to experts, based on the life of national architectural design specification generally sintered brick civilian residential use for 50 years, the useful life is significantly less than the life of unburned brick building. What is more, some practiced on a cottage manufacturers in order to save costs, intends to reduce the ingredients, such as 10% to 15% of cement should be added, the results did not add so much. National Development and Reform Commission of unburned brick production applications has important guiding significance, relevant departments will help develop standards, increased supervision, strengthen and unburned brick production industry self-regulation.
