Problems solved by technology

[0004] The technical problem to be solved by the present invention: Aiming at the problems that the traditional pipeline dredging agent has slow dissolution rate, poor dredging performance, and will cause corrosion to the pipeline, the present invention first mixes enzyme substances such as keratinase, pepsin, cellulase, etc. The mixed enzyme solution is obtained, then mixed with the buffer and evaporated to obtain the mixed enzyme buffer, that is, component A, then mixed with calcium carbide and heated with rosin to obtain a mixed melt, which is spray-dried to produce Granules to get turpentine-coated calcium carbide particles, that is, component B, and finally mix it with component A and inject it into the pipeline

Abstract

The invention relates to a preparation method of a composite enzymatic hydrolysis stable two-component pipeline dredge agent and belongs to the technical field of preparation of a dredge agent. The preparation method comprises the following steps: firstly mixing enzymatic substances such as keratinase, pepsin, cellulase, etc. to obtain a mixed enzyme solution; mixing the mixed enzyme solution and a buffer solution and evaporating to obtain a mixed enzyme buffer solution, namely a component A; ball-milling calcium carbide and mixing the milled calcium carbide and turpentine and heating to obtain a mixed melt liquid, spray-drying the mixed melt liquid and granulating to obtain turpentine-coated calcium carbide particles, namely a component B; and finally mixing the component A and the component B and injecting the mixture into a pipeline. According to the prepared composite enzymatic hydrolysis stable two-component pipeline dredge agent, the problem of slow dissolution rate is avoided. By two-component reaction for dredge, the dredge effect is good and dredge time is short (only 5-8 min). The product contains no toxic substance and will not corrode blocked pipelines.

Description

technical field [0001] The invention relates to a preparation method of a compound enzymatically stable two-component pipeline dredging agent, belonging to the technical field of dredging agent preparation. Background technique [0002] Pipeline dredging agent is a new type of kitchen and bathroom pipeline dredging product, which is mainly used to dredge the blockage caused by various organic substances such as grease, hair, vegetable residue, paper cotton fiber, etc. in kitchen and bathroom pipelines. At the same time, it can also effectively eradicate the attachments accumulated over the years in the pipeline, especially some germs, cockroaches, and flying insects in the pipeline. [0003] At present, pipe dredging agents can be summarized into the following five categories according to the main core functional components of their formulation systems. One is to simply use strong alkali as the main functional ingredient, without chlorine bleaching agent and metal, which wa...
