Abstract
The present invention relates to a process for producing a washing auxiliary agent, namely 4A zeolite. Kaolin group clay used as a raw material is ground, an iron removal agent is then added in the raw material roasted at a high temperature and cooled, NaOH and water are added according to the proportion of 3Na2O, Al2O3, 2SiO2 and 150H2O, a complex iron masking agent is then added, the temperature rises to 90 to 100 DEG C at which the mixed raw material is crystallized, the crystallized mixture is washed by ionized water until the PH value is from 9 to 10, the washed mixture is dried, and then the white 4A zeolite is obtained. The average particle diameter of the zeolite produced by the process is from 2.5 to 3.0 mum, and the calcium ion exchange capacity is greater than 280 mg of CaCO3/g(dry zeolite).
Description
The present invention relates to a kind of is the directly method of synthetic washing assistant 4 A zeolite of raw material with kaolin group's clay.
, partly or entirely replace tripoly phosphate sodium STPP and start from middle nineteen seventies as washing assistant with the 4A zeolite with the environmental pollution that reduces residual phosphorus and cause.The method of producing at present the 4A zeolite has industrial chemicals preparation method (being complete synthesizing process) and with clay preparation method (being semi-synthesis method).In one method of back, Japanese marshy land company adopts wilkinite to make raw material, and this method technology is loaded down with trivial details, and the by-product recovery complex process.U.S.'s ethyl corporation, French Beyer Co., Ltd adopts kaolin to make raw material, with acid treatment and roasting pre-treatment kaolin.This method bothers with the easy contaminate environment of sour deironing, operating procedure.CN1125193A in addition, CN1064850A, patents such as CN1124716A have also been reported semi-synthesis method and have been prepared the 4A zeolite, but these methods require the iron-holder of feed kaolin to be lower than 0.3%, perhaps to kaolinic specification limits too tight (as regulation tubulose kaolin), so resource-constrained.They all are to be raw material with kaolin, are not to be raw material with kaolin group's clay.
The purpose of this invention is to provide a kind of is raw material with resource kaolin group's clay rich and easy to get, the production technique of the semi-synthetic 4A zeolite that production technique is simple.
Technical scheme of the present invention is as follows:
A kind of production technique of washing assistant 4 A zeolite, it be with kaolin group's clay powder be broken to by the order number greater than 200 purpose screen clothes after, with iron removing reagent uniform mixing, roasting at high temperature, cooling back is with 3Na
