Problems solved by technology

Most of them use strong alkali sodium hydroxide and strong oxidant sodium hypochlorite or strong inorganic acid-hydrochloric acid as the main dredging components. Although this kind of chemical pipe dredging agent is chemically active, it is highly corrosive, and it will cause heat generation, splashing, and pressure during use. React with gas, etc., easily cause damage to human body and pipeline, and easily cause environmental pollution

Abstract

The invention discloses a biological composite enzyme pipeline dredging agent, which contains the following ingredients: 5 to 30 percent of protease, 4 to 25 percent of cellulose enzyme, 2 to 20 percent of lipase, 0.05 to 2 percent of wetting agent and 0.05 to 2 percent of thickening and tackifying agent; the ratio of all the ingredients is counted by weight percentages, and the rest is water. The dredging agent is applicable to the pipelines of families, hotels, etc., which has the functions of wetting, infiltration and attachment, and can decompose the stoppage caused by hair, grease, fiber, etc., and the effect is good and the nature is mild; the invention is a green product which is in line with the requirements of environmental protection; furthermore, the invention overcomes the shortcomings that the existing dredging agent contains strong acid, strong alkali or strong oxidant, therefore the pipeline is easy to be corroded, etc., thus having better development and application values.

Description

technical field [0001] The invention relates to a dredging agent and a preparation method thereof, in particular to a pipeline dredging agent prepared from biological compound enzymes and a preparation method thereof. Background technique [0002] Dredging agent is the daily-use chemical article for dredging pipeline commonly used in hotels and families. There are relevant reports in China at present, such as Chinese patents 95108221. Research can be roughly divided into three categories. The first category is to remove blockages through chemical corrosion. The first category is to generate high-temperature melting and loosen blockages through chemical reaction heat generation. The third category is to unclog blockages through chemical reaction to generate pressure. Most of them use strong alkali sodium hydroxide and strong oxidant sodium hypochlorite or strong inorganic acid-hydrochloric acid as the main dredging components. Although this kind of chemical pipe dredging agen...
