Abstract

The present invention relates to a dry chemical cleaning agent for pipeline, in particular, it is a pipeline cleaning agent for cleaning stopage due to greasy dirt, hairs, crumbs from the table and tea dregs for stopped sewer pipeline. Its main ingredients are alkalin metal hydroxide, oxidant, surfactant and metal particles. Said pipeline cleaning agent possesses strong capability for cleaning stopage, and has no corrosion and pollution, and can be extensively used for factory, family and hotel,e tc..

Description

Pipe-dredging agent and preparation method thereof

The present invention relates to a kind of dryness pipe-dredging agent of chemical field and preparation method thereof.

Modern industrial equipment, the sanitary facility in urban public utilities and the family, drainage pipeline are often perplexed by the obstruction that a variety of causes causes.Method commonly used be with manually, machinery is aided with hydrochloric acid etc. and dredges, and wastes time and energy, and also can cause adverse consequencess such as blow-off pipe damage.

In recent years, existing both at home and abroad people has done research to solving the drainage pipeline blockage problem with chemical process.In Japanese Patent J5814800, disclose a kind of water shoot liquid cleaner, this sanitising agent is to mix hypochlorous acid by highly basic in water, tensio-active agent is formed.And for example in the Chinese patent 90108880.3, also disclose a kind of duct cleaning agent, this sanitising agent is by tripoly phosphate sodium STPP, and lactic acid, citric acid, phosphoric acid and causticity benzene sulfonate are formed.Above-mentioned two kinds of duct cleaning agent are mainly used in pipeline and clean, maintain, prevent line clogging.Formulation is an aqua, accumulating, uses not enough safe ready.

The objective of the invention is will be at the industrial water drainage pipe, and lavatory, bathroom, kitchen outfall sewer stop up the problem that lacks the effective chemical dredging agent, provides the thin stifled ability of a kind of decontamination strong, transportation, keeping, safe pipe-dredging agent easy to use and preparation method thereof.

Technical scheme of the present invention is to choose the effective pharmaceutical chemicals of pipe-dredging, and through optimum combination, rational formula mixes, pulverizes, granulates, drying and make a kind of dryness pipe-dredging agent.

Pipe-dredging agent of the present invention mainly contains: alkali metal hydroxide, sodium-chlor or sodium sulfate, oxygenant, non-blushing thinner, metallic particles, tensio-active agent.

The major ingredient of aforementioned tube pipeline dredging agent number by weight percentage is:

Alkali metal hydroxide 5～80%

Sodium-chlor/sodium sulfate 10～25%

Oxygenant 5～35%

Non-blushing thinner 4～15%

Metallic particles 1～20%

The tensio-active agent effective content

Wherein:

1) alkali metal hydroxide can be selected lithium hydroxide, sodium hydroxide, potassium hydroxide etc. for use one or more are composite.

2) oxygenant can select for use one or more of SPC-D, antihypo, Sodium Persulfate, Potassium Persulphate, saltpetre, SODIUMNITRATE etc. composite.

3) non-blushing thinner can be selected talcum powder, Repone K, silica gel, diatomite, paraffin oil for use, a kind of in the Vegetable oil lipoprotein or several are composite.

4) metallic particles is aluminum shot or zinc granule.

5) tensio-active agent is selected a kind of of sodium alkyl benzene sulfonate, succsinic acid, lauric acid, coco-nut oil fatty acid, myristic acid, polyoxyethylene glycol etc. for use or several are composite.

Above-mentioned prescription composition has been given full play to its synergy in pipe-dredging, guaranteed the mediation effect.

The preparation method of pipe-dredging agent is: in the environment of humidity＜50%, material is pulverized, stream temperature is granulated, drying under 50～150 ℃, does moistureproof the processing then, gets product with the metallic particles mixing again.

In aforesaid method, it is 50～150 purpose powder that material should be pulverized, in order to granulation; Simplify technology, the dry step of granulating carries out, and the granulation particle diameter is selected arbitrarily between 0.2～2mm, and the gained particle size distribution is even, and it is spherical that particle shape is preferably.

Below in conjunction with accompanying drawing the present invention is further described.

With reference to accompanying drawing, (1) is material mixer among the figure; (2) be pulverizer; (3) be the fluidized granulating machine; (4) be sifter; (5) be moistureproof treater; (6) be mixing tank; (7) be air dehumidifier.Its manufacturing is metal hydroxides, oxygenant, sodium sulfate or sodium-chlor to be added mixing tank (1) mix; mixture adds pulverizer (2) and pulverizes; send screening in the sifter (4) after sending into tablets press (3) granulation; the screening salable product are sent in the moistureproof treater (5) with non-blushing thinner and are carried out protection against the tide processing, mix promptly getting product at last in mixing tank (6) with metallic particles, tensio-active agent.The coarse grain of screening returns pulverizer (2) pulverizing in the sifter (4), and particulate is sent into and continued granulation in the nodulizer (3).Air just can enter tablets press (3) after air dehumidifier (7) dehumidifying.

Pipe-dredging agent of the present invention is an a kind of dryness chemistry dredging agent, and it has overcome all drawbacks of common methods such as artificial, machinery, has also remedied some deficiency of existing chemical pipeline cleaning agent, for pipe-dredging has been opened up new way.During dredging pipeline, only need to pour product of the present invention into obstruction place, add less water, after 30～40 minutes, pipeline begins through-flow, and the water flushing can be finished mediation work.The present invention can be widely used in the obstruction mediation of industrial water drainage pipeline, lavatory, bathroom, kitchen sewer line, to greasy dirt, and hair, the obstruction that the food tea leaf residual causes is particularly effective.Safety easy to use, no corrosive pipeline.
