Abstract

The invention discloses a membrane silk moisturizing composition and a preparation method and application thereof. The membrane silk moisturizing composition is prepared from following components in percent by mass: 1%-20% of sodium salt humectant, 0.1%-0.5% of sodium hydrogen sulfite, 1%-5% of surfactant and the balance water. The membrane silk moisturizing composition has a good moisturizing effect, meanwhile, has a bacteriostatic effect, has the beneficial effects of being short in flushing time, high in production efficiency and low in production cost when applied to membrane silk production, can be recycled, and is environmentally friendly.

Description

technical field [0001] The invention relates to a membrane silk moisturizing composition, its preparation method and application. Background technique [0002] During the production process of the hollow fiber membrane module, the wet membrane filament needs to be dried, and then the membrane module is cast to ensure the effective curing of the glue. Hollow fiber membranes that have not been treated with humectants are prone to shrinkage of the membrane pores during drying, coupled with the hydrophobicity of the organic polymer material itself, will cause the flux of the membrane module to decrease or even lose flux. In order to solve the above problems, it is usually necessary to add a humectant before the casting of the membrane module to maintain the flux of the membrane module. [0003] Glycerin is the most common humectant at present. It can ensure that the membrane filaments can still maintain a good flux after drying. However, glycerin is sticky, and it is easy to st...
