の向上が望まれていた。Conventional floor fogging equipment sprays directly onto the object to be treated, and performs pre-painting treatments such as degreasing, water washing, and phosphate chemical treatment on metal surfaces of simple shapes, so the amount of spray is relatively small, and the amount of spray is reached directly and indirectly. The insides of automobile doors, floors, tire houses, etc., which are difficult to treat, such as bag-like interiors, back surfaces, and blind spots, are surface-treated without sufficient degreasing, water washing, phosphate chemical treatment, etc. Therefore, in the subsequent steps, they are coated with solvent-based, water-based paints, or powder, but sufficient performance cannot be obtained, and improvements in corrosion resistance have been desired.

表面処理が出来る事を見出して本発明を完成した。In addition, although the immersion method can process objects with complicated shapes such as bags, it has the disadvantage that the processing liquid tank and equipment area are large and the processing time is also long. In order to eliminate the above-mentioned drawbacks, the inventors of the present invention have conducted various studies, and have found that while spraying the processing liquid onto the object to be treated using a fogging device, the inside of the bag-shaped object, which is difficult for direct mist to reach, Metal surfaces can be treated by spraying or spouting a large volume of processing liquid from a sprayer installed separately in the device onto areas such as blind spots, flooding the areas, and maintaining the immersed state for surface treatment. They discovered this and completed the present invention.

The water and treatment liquid are placed in a circulation tank or a tank and heated by an appropriate heating method such as introducing steam or overflowing water into a heater such as a coiled pipe or plate coil installed inside the tank or an external heating device. Although the heating temperature varies depending on the purpose of surface treatment, 50-90 is usually used.

出来る。As the spraying device, for example, a known one is used, in which a conduit with a large number of sprayers arranged in parallel at the top, side, and bottom of the device is arranged in a roughly □ shape so as to surround the object to be treated. A sprayer is installed separately in the device in order to spray or eject a large amount of the processing solution to the bag-shaped interior and blind spots of the processed object, which are difficult for the rare and forged mist to reach when spraying the processing solution. The installation location of this sprayer and the conduit to which it is attached differs depending on the object to be treated, but the sprayer is arranged so that the processing liquid is exposed to the bag, the back side of the lower part, or both of the object to be treated. However, it is preferable to install both the sprayer facing downward from the top of the bag of the object to be treated and the sprayer facing above the position of the wheels, and they can be fixed or moved.

処理物の形状と処理時間により決定される。The separately disposed sprayer may be the same as or different from the sprayer installed in the atomizer, or may be a pipe-like conduit or one with a sealed end and a small hole drilled in the side. The treatment liquid piping is connected to the sprayer of the Akebono fogging device via a pump and conduit from the circulation tank or tank, and to the sprayer via a conduit installed separately in the device. It may be the same as or different from the circulation tank installed in the fogging device or the pump that feeds liquid from the tank to the sprayer.
The spraying equipment varies depending on whether it is a continuous type or a batch type, and it also differs depending on the shape of the object to be treated and the processing time. Batch-type forgery equipment places the sprayer at an appropriate position depending on the shape of the object to be processed.
Spray the treatment liquid or cleaning water from a sprayer. The amount of mist liquid is determined by the shape of the object to be processed and the processing time.

連続式の頃霧装置の場合は噴霧器の配列又は噴霧器の頃
霧容量を初期蹟霧と補給階霧で異なる様にする。In the case of a continuous type misting device, the arrangement of the sprayers or the sprayer mist capacity should be different between the initial fog and the replenishment stage fog.

初期燈霧容量で補給頃霧しても良いが、項霧装置の循環
タンクが大容量必要となり、処理液加温の為のエネルギ
ーが増加する。Although it is possible to perform fogging at the initial fogging capacity at the time of replenishment, a large capacity circulation tank of the fogging device is required, and energy for heating the processing liquid increases.

又初期の頃霧容量で補給噴霧すると処理液の化学反応が
促進され、処理液中の薬剤の消費が増大し、反応生成物
が増大、沈降し、ポンプにより噴霧器に導入され、噴霧
器が閉塞する機会が多くなる。In addition, when supplementary spraying is carried out at the initial mist volume, the chemical reaction of the processing liquid is accelerated, the consumption of chemicals in the processing liquid increases, the reaction products increase and settle, and are introduced into the atomizer by the pump, causing the atomizer to become clogged. There will be more opportunities.

バッチ式及び連続式燈霧装置の初期頃務時間は３硯砂以
下で好ましくは１の砂以下の短時間で被処理物内に処理
液を贋霧又は流入させ溢水させる。The initial operating time of the batch type and continuous type atomization apparatus is a short time of 3 inkstone sand or less, preferably 1 inkstone or less, and the processing liquid is misted or flowed into the object to be treated to overflow.

この噴霧が達成出来る頃霧能力の事を大容量といつｏ初
期噴霧液量が少なく初期頃霧時間が３晩砂以上に及ぶと
リン酸亜鉛皮膜の生成面積が少なくリン酸鉄皮膜の生成
面積が増大し、又錆発生の機会も増大するので塗装後の
防食性を大中に向上させる事が困難となる。When this spraying can be achieved, when the fog capacity is set to a large capacity, the initial spraying liquid volume is small and the initial fogging time is longer than 3 nights, the area where the zinc phosphate film is formed is small and the area where the iron phosphate film is formed. Since this increases the chances of rust occurring, it becomes difficult to improve the corrosion resistance after painting.

補給墳霧時間は処理液、被処理物の種類、形状により異
なるが、通常脱脂工程では３の砂以上好ましくは６０〜
１８０秒である。The replenishment time differs depending on the processing solution, the type and shape of the object to be processed, but in the normal degreasing process, sand of 3 or more is preferably 60 to 60.
It is 180 seconds.

~120 seconds. If the replenishment spraying time in the degreasing step or the zinc phosphate chemical conversion treatment step is less than 3 silica sands, degreasing or chemical conversion will be insufficient. 'In each water washing step, the washing time is preferably 1 second or more, depending on the amount of spray liquid, but preferably 10 to 6 inkstone sand.

１秒以下では水洗が不充分である。If the time is less than 1 second, washing with water is insufficient.

初期及び補給曙液の贋霧圧は０．３ｋ９／地（ゲ−ジ圧
）以上であるが好ましくは１〜５ｋ９／の（ゲージ圧）
である。The mist pressure of the initial and replenishment liquid is 0.3k9/ground (gauge pressure) or more, but preferably 1 to 5k9/gauge pressure.
It is.

バッチ式及び連続式の初期噴霧量は脱脂工程に於ては初
期噴霧、補給頃霧との区別は特に必要はない。In the degreasing process, there is no particular need to distinguish between the initial spray amount and the replenishment mist in the batch type and continuous type.

合と種々ある。When considering the consumption of epargy, it may be better to separate the initial period and the supply counterfeit period. In the early stage, the ratio of the amount of mist to the amount of sprayed liquid supplied to the bucket varies depending on the shape of the object to be treated, such as 3:1, 2:1, and 1:1.

処理液を被処理物全体に溢水させるに要する時間を袋状
内部の化成状況の関係は次の通りである。The relationship between the time required for the treatment liquid to flood the entire object to be treated and the chemical formation state inside the bag is as follows.
