Workwear builders are divided into organic work clothes, work clothes, builders and inorganic work clothes and builders. The inorganic work clothes builder is dissolved in water and dissociated into charged ions, which are adsorbed on the surface of the dirt particles or fabric, which is beneficial to the stripping and dispersion of the dirt. Commonly used inorganic work clothes builders are sodium tripolyphosphate, water glass, sodium carbonate, sodium sulfate, sodium perborate and the like. Organic builders have the effect of preventing soil reprecipitation. Commonly used organic work clothes builders are sodium carboxymethylcellulose. In addition, there are fluorescent whitening agents, enzyme preparations, colorants and flavors.
Soft water function: The layer of sodium silicate has a strong softening ability to water, and the binding ability to Ca2+ and Mg2+ is 300mg/g and 400mg/g, respectively. The reason is that sodium silicate is an ordered polymer structure. In ordinary hard water, sodium ions are quickly replaced by Ca2+ and Mg2+ in water, and the network structure of sodium silicate is stabilized.
Stable pH performance: When lg layer of sodium silicate is contained per liter of water, the pH of the aqueous solution can reach 9.5-12, so it can provide and maintain the stable alkalinity required in the washing process, so that the washing products can fully exert the washing efficiency. .
Anti-redeposition ability: Sodium silicate can save 20% active combination in medium hardness water compared with other work clothes builders (such as sodium tripolyphosphate, 4A zeolite, sodium metasilicate). Its decontamination index It is 1.6, higher than sodium tripolyphosphate (with a decontamination index of 1.5) and 4A zeolite and sodium metasilicate (with a decontamination index of 1.1). It can effectively change the hardening and kneading phenomenon of fabric fibers, and to dirt particles and The oil stain has a good suspension effect and can exert a good anti-settling ability.
