Problems solved by technology

[0004] The alkaline cleaners reported in existing literature generally only contain strong bases, or a combination of strong bases, complexes, and surfactants. This kind of cleaners has simple components and poor cleaning effect. For example, the publication number is CN The cleaning agent disclosed in the patent application of 1025553452A
At present, the commonly used alkaline cleaners on the market, such as the LC-90 membrane cleaner of a Xiamen Membrane Environmental Technology Co., Ltd., although the effect of the detergent is relatively satisfactory, the price is too high, and the cost of the enterprise's use is too high. high

Embodiment 1

[0032] The preparation of embodiment 1 alkaline cleaning agent of the present invention

[0033] Composition: 10wt% sodium hydroxide, 5wt% AEO, TX-85wt%, 5wt% AES, 3wt% sodium sulfate, 1wt% sodium nitrite, 2wt% ethanol, 0.2wt% foam enemy, and finally add water to 100wt%.

[0034] Preparation method: First, take an alkali-resistant container with a stirring paddle on it, and PP and PTFE are preferred. Weigh each substance according to the volume of the container and the above-mentioned ratio, first in an open container (such as a plastic vat), add a solid alkali, such as sodium hydroxide, and then add other solid components, and mix it in a three-dimensional mixer or other stirring equipment After fully stirring, pour it into the above-mentioned alkali-resistant container, add a small amount of water and stir evenly; then add liquid components other than water into the alkali-resistant container, such as AEO, AES, ethanol, etc., this operation must be added While stirring to p...

Abstract

The invention discloses an alkaline membrane washing agent. The alkaline membrane washing agent comprises the following components in percentage by weight: 5wt%-30wt% of inorganic alkali, 1wt%-20wt% of a surfactant, 0-10wt% of an auxiliary washing agent, 0.5wt%-3wt% of a membrane protection agent, 0-10wt% of an alcohol ether type solvent, 0-1wt% of a de-foaming agent and the balance being water. The alkaline membrane washing agent has a good washing effect, and a good market application prospect and the cost is lowered.

Description

technical field [0001] The invention relates to an alkaline membrane cleaning agent and a preparation method thereof. Background technique [0002] Membrane is a material with selective separation function. The process of using membrane selective separation to realize the separation, purification and concentration of different components of feed liquid is called membrane separation, which has been widely used in chemical industry, water treatment, food and biochemical industry, textile leather industry, paper industry, Healthcare and other fields. At present, the existing membranes include one or several types of membrane groups produced by organic or inorganic materials such as microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, and RO reverse osmosis membranes. The microfiltration membrane can intercept particles between 0.1-1 micron. The microfiltration membrane allows macromolecules and dissolved solids (inorganic salts) to pass through, but...
