Description

Make the method for detergent composition with non-tower process
Invention field
The present invention relates to a kind of non-tower method of producing shot shape detergent composition in general.What more particularly, the present invention is directed to is a kind of by adding a kind of tensio-active agent and coat the continuation method that material is produced detergent agglomerate in a series of mixing tanks.Present method is produced a kind of detergent composition of good fluidity, and its density can be regulated in very on a large scale according to human consumer's needs, and this washing composition can be sold on market.
Background of invention
Recently the detergent industry field is for " fine and close ", thereby is that the cloth-washing detergent of low consumption has shown great interest.For promoting the production of so-called low consumption washing composition, people are to high bulk density washing composition, and for example density is that many explorations have been carried out in 600g/l or higher washing composition production.Because low consumption washing composition can be saved resource and sell with the small packages that is more convenient for the human consumer, therefore at present they there is very big demand.But just say what degree is the New-type detergent product needed " compress " and be still uncertain in nature.The human consumer of in fact many human consumer, especially developing countries still has a preference for a kind of higher amounts in its laundry operation.
The preparation method that the detergent particles or the powder of two kinds of main types are arranged usually.First method is included in the detergent slurries of a kind of water-based of spraying drying in the spray-drying tower, to produce highly porous detergent particles (for example tower production technique of low density detergent composition).In the second approach, do various washing composition batchings mixed, use a kind of tackiness agent then, for example a kind of nonionic or anion surfactant gather together them, to produce high density detergent composition (for example agglomeration production technique of high density detergent composition).In above two kinds of methods, the important factor of controlling the density of prepared detergent particles is said coating of particles, porosity and size-grade distribution, the density of various raw materials, shape and their chemical constitutions separately.
Many trials have been carried out in the art, so that the method that can improve detergent particles or powder density to be provided.Given special concern for handling the densification that realizes spray-dried granules with (post tower) behind the tower.For example, a kind of trial comprises a kind of batch technology, at a Marumerizer _In make through spraying drying or granulation, contain the detergent powder densification and the spheroidization of tripoly phosphate sodium STPP and sodium sulfate.This equipment be included in one in fact vertical, have in the cylinder of smooth-walled and one of bottom level in fact, coarse turntable.But this method is a kind of batch technology basically, therefore is not suitable for the production of large-scale detergent powder.Recently various other trials have been carried out, so that the continuous processing that improves through " behind the tower " processing or spray-dried detergent pellet density to be provided.This class technology generally needs one particle to be pulverized or ground primary equipment and one improve by the second set of pulverized particles density by nodulizing.Though these class methods are by handling or make " behind the tower " or spray-dried granules densification realize that required density improves, the ability that further improves the surfactant activity component concentration without subsequently encapsulation steps but is restricted.In addition with regard to the complexity of economy (high capital cost) and operation, utilize " behind the tower " handle or densification not favourable.And all aforesaid methods mainly all are densification or processing treatment at spray-dried granules.Recently the relative populations and the kind that participate in the raw material of spray-drying process in detergent particles production are restricted.For example be difficult to obtain the high surface agent content in the detergent composition that obtains, this characteristics are impelled in a kind of more effective mode and are produced washing composition.Therefore wishing has a kind of method, can not be subjected to the added restriction of conventionally spray-dried technology and produces detergent composition.
This area has disclosed many methods with the detergent composition agglomeration process for this reason.For example attempted in a mixing tank, zeolite and/or layered silicate being mixed, made the detergent component agglomeration, formed free-pouring agglomerate.Though these attempt to propose and can produce detergent agglomerate with these class methods, do not propose a kind of the detergent raw material that becomes mashed prod, liquid and dry material can be gathered into effectively crisp, the mechanism of the free-pouring detergent agglomerate of energy.
Therefore this area still needs a kind of agglomeration (non-tower) technology that can the continuous production detergent composition, and this washing composition has the high-density that can directly obtain from the washing composition original ingredient, and its density can be regulated by processing condition.Similarly, still need a kind of more effective, more flexible and more economical method, can on the limiting density of (1) final composition, handiness be arranged to impel, and (2) with some different types of washing composition batchings, and especially washing composition of liquid form batching is added to and produces washing composition under the situation that handiness is arranged in the process on a large scale.
