Background technology
The chemical mode of dredging cleanser conduit is generally by enzyme (or microorganism) or highly basic, dissolves organic tamper such as grease, hair, and killing microorganisms keeps duct cleaning unimpeded.With enzyme (or microorganism), cost is higher conventionally, and effect is slow, and the low effect of cost is fast to use highly basic.Therefore strong basicity product is still the main flow of current pipe-dredging agent.
At present, strong basicity pipe-dredging agent can be summarized as following five classes by main core effect composition of its formula system.
The one, merely using highly basic as main composition, not chlorine-containing bleaching and metal.Early stage pipe-dredging agent adopts this class more, and its formulation composition is simple, handling ease, cost are low, but product dissolves slow, poor performance.
The 2nd, highly basic and chlorine float the combination of agent.Introducing chlorine floats agent and can obviously improve product to the organic removing effect of line clogging, and patent CN02138426.6, CN03115938.9, CN20110330367.6 belong to this class.But it is high that chlorine floats agent consumption, there is the deficiencies such as Odor stimulation, large to metal protection, product dissolving is slow.
The 3rd, the combination of highly basic and active metal.After highly basic and active metal chance water, vigorous reaction heat release can improve the low temperature result of use of product, produces hydrogen simultaneously and plays " boiling " effect, can accelerate the dissolving diffusion of highly basic.The active metals such as use aluminium alive, zinc, magnesium, it is strict that its production process requires moistureproof and waterproof, and product in use heat release is violent, more easily causes the distortion of pipeline local softening, and generation hydrogen has certain security risk.
The 4th, highly basic, oxygen float agent or chlorine and float agent, active metal three's combination.This class system stability is difficult point, and process for processing, packing and storing require strict to the control of water, and heat release is violent in use also produces hydrogen and oxygen simultaneously, and danger is larger, has adopted respectively this two kinds of modes in patent CN90108009.8 and CN95111481.6.
The 5th, on the basis of the above, also add other effect composition, as patent CN95111633.9 has also adopted S-WAT, rare earth.
Highly basic and oxygen float agent combination, and its stability that coexists is an industry difficult problem.Because solid alkali (as sodium hydroxide) has very strong moisture absorption ability and moisture absorption heat release, easily caking; Oxygen floats meeting in agent (as SPC-D) storage process and when slowly decomposition discharges efficient oxygen, produces water; And highly basic itself will significantly accelerate oxygen and float the decomposition of agent.Therefore, solid alkali and oxygen float agent very difficult stable coexisting conventionally.When formula or inappropriate technology, the two very easily occurs living, and oxygen loss is too fast, product caking equistability problem.
The oxygen of living can provide the bleaching bacteria-eliminating efficacy of environmental protection gentleness, and the oxidative stability of living has very large direct or indirect impact to the performance of this product.Oxygen raw material alive too quick decomposition in product shelf life, the one, make product cannot play in use foaming, dissolution, the degerming texts of expection; The 2nd, after the water that decomposition produces is absorbed by highly basic, generate crystal water, cause its solution heat significantly to reduce, dissolve and the decline of dredging effect; The 3rd, produce water and also can cause product caking when more when decomposing, the serious problems such as cannot use.
