Technology of TAKEROKU -Protection from insects of Bamboo-


Vacuum pressure injector  

Vacuum pressure vacuum pressure injection method is adopted to fully penetrate to the center of bamboo by drug


The big question on the use of bamboo "insect damage" is a vacuum-pressure injection of the drug is to stand out against the repellent effect. Specifically, after installing a bamboo pressurized aircraft vacuum infusion, vacuum injection of the drug to the board, we are pressurized. I can make enough to penetrate the bamboo inside the drug by this. The dip coating method is particularly effective in the thick bamboo not get the full effect. Also, you can also reduce the occurrence of mold in conjunction with the insecticide.


Pressurized injector vacuum


The vacuum pressure to the injection of a drug made by the compactor Koshiipurezabingu Corporation. Carrying out the opening and closing the doors of the bamboo-shaped drums, all operations can be done collectively in the control panel. Chinami, the total time required for vacuum-pressure injection process is about three hours.


Vacuum treatment because


By bleed air contained in the bamboo fiber, inner corner of the various drugs to be able to penetrate. Vacuum can be obtained 20 to 30 minutes to complete.


Quantity 1 processing times


Depending on the thickness of the bamboo and an average of one per 30 to 40 can be treated with insecticide at the same time this action.


Night Estimated pressure


Done through the thick bamboo is by far the section in advance. Pressure is 8 atm. If the scribe is to rid of the section to prevent rupture of the expansion done in about three atmospheres.


Time pressure


Pressure (8 atm) for about 90 minutes, low pressure (3 atm) If you do a pressure of about 60 minutes. Drugs can penetrate deep in to this pressure by the bamboo.


Drug types


Bamboo-only drug "Gazette bamboo" is used. Highly effective insecticide, is a colorless, odorless and highly safe drug.

Long-term results of experiments conducted nearly 10 years of 100 percent sure a phenomenal insect repellent. Reported the results of trials investigating the effect of bamboo insect vacuum pressure by drug infusion (Kinki Ming bamboo insect Council) are. Mousou Kyoto bamboo Bamboo is a "bamboo circular drawing", using drugs is "bamboo Gazette" was used. After the injection pressure, conducted a survey of 10 years Taketorakamikiri escape hole, four-year period of harvested wood in one 試竹 not a book one served only a single exit hole was observed, almost 100% had a repellent effect.
(Note: one hole out of the first year in treatment and injection drugs were tested at the time made of bamboo is irrelevant)
