Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a method of treating insects, preservatives, and antibacterial agents for buildings, and insect repellents, preservatives, and insecticides for lower floors, shed members, and wooden parts of indoor spaces. The present invention relates to a simple and inexpensive treatment method and a pipe structure used for the treatment method, in which a pipe having a limited material is provided without the germicide digging into the space, and the health of the duster is measured.

[Conventional technology]

A. As disclosed in Japanese Utility Model Application Laid-Open No. 61-115405, a method of piping under the floor and supplying an insect repellent and a preservative from the piping is known.

B. As disclosed in JP-A-62-288241, a method is known in which a drug accumulation line is provided under the floor to spray the drug and forcibly stir to kill pests.

C. As disclosed in Japanese Examined Patent Publication No. 54-3108, a groove-shaped cover with lateral openings is provided in the wood part of a wooden building, and a sponge-like absorbent mat impregnated with an insect repellent is inserted into the opening. Pest control devices are known.

There is no limitation on the material of the pipe used in the method A. Therefore, even in the case of stainless steel pipes, corrosion is promoted by chemicals, and there is a problem in long-term service life. Further, the ejection port has a piping structure having an ejection port connected to the main pipe, and there is a problem in the sprayed state of the drug.

Regarding B as well, there is no limitation on the material of the pipe, there is a problem in service life, and the treatment method is different.

Regarding the C method, the treatment method is different, and there is no limitation on the material of the groove-shaped cover, so there is a problem in service life.

The present inventors have spent several years to solve the above problems,
After repeated tests on the pipe material that can withstand the strong corrosiveness of chemicals, it was found that the polybutene pipe has that condition.

After that, further tests were conducted to investigate the corrosion relationship between strong chemical components and pipes. As a result, it does not corrode over a long-term service life of 25 years or more, piping work is easy, it is inexpensive, and the structure allows chemical spraying. Since it is not necessary for a person to go under the floor or under the floor on the second floor, it is possible to manage the health of the sprayer, and to provide a treatment method capable of simultaneously performing insect repellent, antiseptic and antibacterial treatment, and a pipe structure used for the method. To do.

[Means for Solving the Problems]

In order to achieve the above object, the material of the pipe used in the treatment method of the present invention has a molecular formula Limited to The reasons for limitation will be described later (Table 1).
A large number of at least two ejection holes are provided in the pipe, and the pipe is arranged under the floor during the new construction or under the second floor, in the shed and the wooden portion of the indoor space.

Since the polybutene pipe has a tensile elastic modulus of 3200 Kgf / cm ² and is soft and rich in bending property, it can be freely arranged under the floor, under the second floor, in the shed and in the wood of the indoor space. Further, it is preferable to dispose the spout hole downward in the disposition of the soil liquid pipe, and to dispose the spout hole perpendicular to the xylem surface in the disposition of the wood part liquid pipe. Absent.
It is preferable that at least two spray holes are provided at one location along or cross the flow direction of the chemical liquid, and the angle is an angle at which the chemical liquid sprayed from the two spray holes intersects. The method of press-fitting the chemical solution may be performed from both ends of the pipe, or may be performed from only one end by closing the other end of the pipe.

By thus intersecting the chemicals, the chemicals are efficiently impregnated into the soil or xylem while forming a spray.

As a typical chemical solution used in the present invention, A: Longlar 30 as a soil treatment solution, B: Sunplus 60 as a xylem treatment solution.
(Longlar 30: Sunplus 60 = 1: 2 blended) as well as Allinon CP oil, Yamasaw Baliside oil, VELCP4
0, alinone chlorpyric 20-FL, lentlek oil, emulsion, etc., but are not limited thereto. The action of these agents includes insect repellency by insecticides such as termites, wood worms, cockroaches, millipedes, centipedes, and walking insects, as well as antiseptic, bactericidal and antifungal effects.

[Action]

The reasons for limiting the material of the pipe used in the method for treating insects, preservatives, and germs thus constituted will be described. Chemical liquids such as termites have a very strong insecticidal action, and stainless steel pipes and hard vinyl chloride pipes made of existing materials are corroded and cannot withstand long-term service. Therefore, chemical sprayers go under the floor or under the floor on the second floor to make a hole in the wooden part of the base to pressurize the chemicals or directly press-impregnate the soil under the floor and repeat the same work several years later. On the other hand, on September 11, 1986, the former drug, chlordane, was designated as a specific chemical substance under the Chemical Substances Control Law, and the protection of the health care of the sprayers was strengthened. In addition, stainless steel pipes and hard vinyl chloride pipes are expensive even if the service life is ignored, and the number of man-hours required for piping processing is high, and it is the current situation that those skilled in the art are in a squeeze on the measures. The results of satisfying these various conditions are summarized in Table 1, and the pipe material used in the present invention is limited to polybutene.

As described above, the pipe material used in the treatment method of the present application is limited to the pipe made of polybutene resin, and since the linear expansion coefficient and the tensile elastic modulus are low, the pipe arranging work and the ejection hole processing work are very easy. Moreover, since the chemical solution is cross-injected from the two ejection holes without passing through the nozzle, it is impregnated into wood, space and soil as a spray state, and the spraying efficiency of the chemical solution is greatly improved. .

〔Example〕

Polybutene pipe for soil (1): Outer diameter 13mmφ Wall thickness 1.5mm Jetting hole (2): 1mmφ Crossing angle (3) 90 ° Two holes in one place 1m space apart Opening part is downwards Wood part Polybutene pipe (4): Outer diameter 10mmφ Wall thickness 1.5mm Injection hole (2): 1mmφ Crossing angle (3) 120 ° Two holes in one place 50cm interval Opened upward and wood part (8) surface Disposed 1 cm away from chemical liquid (5) A liquid (for soil): Longral 30 (Propane tanphos 15% S421 15% balance water) Injection volume 0.8-1.5 l / min B liquid (for wood): Sunplus 60 ( Contains 60% of trihalol preservative A liquid: B liquid = 1: 2, the balance of the remaining water) Injection amount 0.7-1.2l / min Injection pressure with pump (6): 10-15kg / cm ² Press-in time: 1 to 10 minutes Polybutene pipe (7) pulled out of the building or in the storage
A pump (6) was connected to both ends of the solution, and both solutions A and B were press-injected under the above-mentioned conditions to impregnate the wood soil with the chemicals in a sprayed state (9) to perform insect repellent, antiseptic, and antibacterial treatment. After processing,
The chemicals were washed by injecting air or water into the polybutene pipe.

The polybutene pipe (7) was placed before the flooring work for new construction. The same polybutene pipe (7) may be provided in the wooden part (8) under the floor under the second floor, the shed and the indoor space (not shown), but it may be provided in the existing building. The termite retreatment may be performed once every five years, but other pests may be treated every year.

〔The invention's effect〕

Since the present invention is configured as described above, it has the effects described below.

By using polybutene pipe, even if a strong chemical is used, corrosion does not progress and it can withstand long years of use, and because of its structure, it is not necessary for the sprayer to go under the floor, under the second floor, under the roof or in the indoor space. Health management has improved significantly,
It has become possible to reduce processing costs. Since the polybutene pipe is soft and has the property that it can be bent freely, the installation work is easy and the material cost of the pipe can be reduced to 1/2000 that of the stainless pipe as shown in Table-1. The spraying efficiency was greatly improved by the method of press-fitting the chemical liquid from both ends of the pipe and by ensuring the spray state by intersecting the chemical liquid injected from at least two ejection holes.

Since the chemical solution can be completely sprayed under the floor, under the second floor, in the rooftop and every corner of the wooden space in the indoor space, the insect, antiseptic and antibacterial effects were perfect.
