sodium zeolite

The status quo of the research on phosphate free builders is introduced and the properties of 4A zeolite, sodium metasilicate, sodium polyacrylate, zeolite P, sodium salt of maleic anhydride acrylic acid copolymer, layered crystal sodium disilicate as phosphate free builders are reviewed.

综述了无磷洗涤助剂的开发进展，并对4A沸石、偏硅酸钠、聚丙烯酸钠、沸石P、顺丁烯二酸酐丙烯酸共聚物钠盐、层状结晶二硅酸钠等助剂的性能作了评述；

The quality authentication problem of zeolite 4A of builder as substitute for phosphate of zeolites and crystalline layered sodium disilicate of builder as substitute for phosphate of silicate system were introduced in detail.

重点介绍了沸石类代磷助剂中4A沸石和硅系代磷助剂中层状结晶二硅酸钠的质量鉴别问题。

Tetraethyl ammonium hydroxide ( organic template), silica gel ( silica source) and sodium meta-aluminate ( aluminum source) were used to p-zeolite synthesis and template removal in microwave radiation.

以粗孔硅胶为硅源，偏铝酸钠为铝源，四乙基氢氧化铵为模板剂，在微波辐射条件下，合成β沸石并脱除模板剂。

Scholars at home have started to research 4A zeolite since 1980's, and then other substitutes were developed, such as, precipitated silica, complex sodium disilicate and layered crystal sodium disilicate.

国内学者从80年代开始研究4A沸石起，先后开发出了沉淀二氧化硅、复合二硅酸钠、层状结晶二硅酸钠等代用品。

In the field of detergent ingredients, sodium tripolyphosphate. zeolite A and crystalline layered disilicate SKS-6 are well-established builders.

在洗涤剂组分中，三聚磷酸钠、A型沸石和层状结晶二硅酸盐SKS-6已是被广泛接受的助剂。

Zeolite ( 4A) and sodium metasilicates are largely used as phosphate-free detergent builders in industry. There is a potential pollution because of the zeolite containing Al 3+. The softening water capability of sodium metasilicate is poor.

目前工业上大量使用的无磷洗涤助剂为4A沸石和偏硅酸钠，4A存在潜在的铝污染问题，而偏硅酸钠的抗硬水性差。
