Abstract

The present invention relates to a method for preparing a high-efficiency detergent which is used for cleaning airport runways. The high-efficiency detergent is prepared from the following components according to the percentage by weight: 35 to 62% of dichloroethane or methyl chloroform, 22.7 to 48.7% of toluene, 6.7 to 12.8% of No. 2 solvent naphtha, 0.5 to 1.2% of N, N'-diphenyl thiourea, 0.8 to 1.0% of petroleum sodium sulfonate, 100.1% of OP and 1.2 to 2.2% of methanoic acid. The components are orderly added to a container at a normal temperature and sufficiently and uniformly stirred. When the high-efficiency detergent is used for cleaning airport runways, two cistern cars work tandem at a time interval of 10 minutes. The former car contains and sprays the high-efficiency detergent, and the later car contains water and flushes airport runways with water under a pressure. The high-efficiency detergent is easy to prepare. When the high-efficiency detergent is used for cleaning, hard rubber residue on the surface of a runway can be rapidly and thoroughly cleaned, and the surface of the runway can not be damaged. The high-efficiency detergent is a runway detergent with high safety and reliability.

Description

A kind of preparation method of efficient airfield runway clean-out system

The present invention is a kind of preparation method of efficient airfield runway clean-out system, belongs to the preparing technical field of clean-out system.

Airfield runway especially aircraft frequently rises, falls on the runway in highway section, by to produce huge rubber part end that friction produced residual with plane tyre and road surface, through travelling and friction high temperature that high speed impact power when landing produces of large-tonnage aircraft, make the residue type become hard and slick dirt layer, this dirt layer slides the high speed of aircraft on runway can constitute unsafe factor.Therefore, for the generation that prevents accident must be carried out regular cleaning to airfield runway, with the safety of guaranteeing that aircraft travels.To so far, on the method for cleaning of existing airfield runway road surface dirt, almost all adopt the physics washing out method both at home and abroad, on bigger airport, generally use the high-pressure water jet patterning method, and artificial removing method is adopted on domestic most of airport.The high-pressure water jet patterning method is that water is forced into 2400～3000kg/cm ², and passing through aperture ejection by the rubber layer cutting of high-velocity fluid with the road surface, the rubber that will cut out with poor car washes away again.But this class mechanical means costliness and efficient are not high.Therefore, the dirt layer cleaning of airfield runway be sought after a kind of efficiently, cleaning means fast take out stains.

The objective of the invention is still to adopt the physics washing out method or manually remove method in order to solve existing airfield runway cleaning, problem and shortcomings such as its mechanical means costliness, efficient is not high or labor cleaning's time long, capital investment is big, it is artificial in a large number to need, expense height are developed a kind of preparation method who invests the clean-out system of the cleaning airfield runway dirt little, that expense is low efficiently, fast, again.

The present invention realizes by following technical proposals: efficient airfield runway clean-out system is under the condition of well-ventilated, normal temperature (20～30 ℃), weight percent according to following prescription joins solvent in the container of belt stirrer according to the order of sequence one by one, and it is stirred fully and can be prepared from:

(1) ethylene dichloride or trichloroethane 35.0～62.0%

(2) toluene 22.7～48.7%

(3) No. 2 solvent oils 6.7～12.8%

(4) N, N '-diphenyl thiourea 0.5～1.2%

(5) petroleum sodium sulfonate 0.8～1.0%

(6) the alkylaryl Soxylat A 25-7 0.1%

(7) formic acid 1.2～2.2%

For the embodiment of three different ingredients, can select different ingredients by the temperature and the ambient moisture of Various Seasonal: (unit in the prescription all is weight percentage) below

Sequence number	Raw material	Embodiment 1	Embodiment 2	Embodiment 3
					(1)	Ethylene dichloride or trichloroethane	35.0％	54.0％	62.0％
(2)	Toluene	48.7％	31.4％	27.7％
					(3)	No. 2 solvent oils	12.8％	11.3％	6.7％
(4)	N, N '-diphenyl thiourea	1.2％	0.8％	0.5％
					(5)	Petroleum sodium sulfonate (surfactant A S)	1.0％	0.9％	0.8％
(6)	The alkylaryl Soxylat A 25-7	0.1％	0.1％	0.1％
					(7)	Formic acid	1.2％	1.5％	2.2％

Embodiment 1 (prescription 1): this prescription is because the boiling point of hydrochloric ether is relatively low, the dry weather that this prescription is adapted to winter uses, its the fastest swelling rate is first minute 16%, and rubber was peeled off the time on road surface no longer than ten minutes, and final swelling ratio is 28%.

Embodiment 2 (prescription 2): this recipe ratio is suitable for round-the-clock operation, and the fastest swelling rate is first minute 18%, and final swelling ratio is 26%, finally peels off the road surface time to be no more than 10 minutes.

Embodiment 3 (prescription 3): the hydrochloric ether content of this prescription is higher, and its penetrating quality is comparatively superior, and the fastest swelling rate is first minute 21%, and final swelling ratio is 24.5%, and this prescription is adapted to the humid climate in spring.

Above-mentioned three embodiment all carry out on airfield runway, and the final swelling time of the airfield runway clean-out system that three different ingredients systems are joined all is no more than 10 minutes.Final swelling ratio---promptly be sprayed on rubber resistates surface with this clean-out system after, the increase of resistates final volume and the ratio of original volume.

Clean airfield runway with efficient airfield runway clean-out system of the present invention following advantage and positively effect are compared with prior art arranged: (1) is used clean-out system of the present invention and can be effectively will be remained in the quick swelling of rubber resistates in the airfield runway dirt layer, loosening, and then the force of cohesion that makes residual body reduces and separates automatically with the road surface, therefore, available 〉=6mg/cm ²The water of hydraulic pressure just can be fully remove its flushing clean; (2) this clean-out system has the rapid osmotic performance, can be in 5～10 minutes, dirt layer on the runway is peeled off the road surface, therefore, it is efficient, quick to clean airfield runway, and not only save time and also can utilize the airport existing installation to make that capital investment is few, expense is low, simultaneously can safety, clean up the airfield runway road surface up hill and dale, overcome that the clearance time that existing physics purging method or artificial purging method exist is long, capital investment is big, artificial many etc. the shortcomings of cost.For example, the runway road surface that need clean a medium-sized airport is about 27000 meters ², press the physics purging method, if the operating speed that adopts high pressure water to clean is 80 meters ²/ hour, need 338 hours altogether, promptly need 67 nights (rolling over 5 hours meters every night), if adopt the vehicle spray Cleaning for High Capacity of clean-out system of the present invention, the spray width is 3 meters, 16 meters/minute of automobile rate of advance then per hour can feelings be washed 2700 meters of processing ², only need promptly to need altogether in 10 hours 2 night just capable of washing disposing.The labour cost of comparing saving with artificial purging method is more surprising; (3) clean airfield runway with this clean-out system, quick, the thorough removing of rubber dirt layer that is accumulated in the airfield runway can not damaged the road table, can reach the requirement that aircraft drives safely in runway.

Enforcement of the present invention, use-pattern are simple: (1) by the described preparation method of top specification sheets, promptly by hundred parts of ratios of described formulation weight each solvent is added according to the order of sequence one by one to stir, and promptly can be made into this clean-out system; (2) airfield runway clean-out system spray of the present invention is adorned in common operation after employing two platform trough cars one in front and one in back were separated by 10 minutes, foreground tank car, and backstage tank car dress water is forced into 〉=6kg/cm ²Hydraulic pressure flushing with whole realization automaticmachiness operations, can save time, less manpower, reduces investment, reduces expenses, not only totally thoroughly but also safe and reliable, convenient, fast.
