The main phosphate substitute builder in detergent field is still focused on 4A zeolite. More manufacturers will pay close attention to the cost/performance for layered silicates.
The solid content of the original art is 90~100kg/m~3. After the art is improved, the solid content is increased to 120~140kg/m~3,which is increased about 30%. It can produce 4A zeolite of excellent performance, used as cleaning additive in the detergent industry, by controlling the hydrothermal synthesis of purified red mud solution and sodium silicate.
Application of 4A-zeolite builder will have a more development in detergent industry by perfecting the technology of synthesize 4A zeolite, enhancing quality, reducing cost and normalizing market. These will be supported by issuing corresponding laws of environmental protection.
The technical progress of surfactants/detergents field in China is concluded in six aspects as listed below:1.Technical progress of main surfactants and the raw materials,such as LAB fatty alcohols,fatty amines and fatty acids,as well as the sulfonation and ethoxylation processes;
The present work is the first attempt in our country to seek an effective method for the treatment of detergent industrial wastewater. By using artificially prepared detergent industrial wastewater, it reveals that the tower biological filter can effectively overcome the foaming problem that cannot be solved by other general aerobic biological wastewater treatment methods, and it reduces the concentration of LAS and COD in wastewater to some extent. Owing to the positive results, this method has now been re...
In this paper,the technology of synthesizing cleaning agent 4A- zeolite from kaolin ofNei Monggol is introduced. It is known that the processes of acidizinq and roasting and thesynthesizing conditions all give effect to the quality of the 4A-zeolite synthesized.Therefore,this paper aims at the cieaning agent industry so asto prepare synthesized 4A- zeolite withthe best major performances.
S'is a great transform period of detergent industry of USA. The motive force of the transform is follows: environmental protection, technique innovation and worldwide trend of detergent.
