When used in conjunction with a deodorizer, it is possible to easily predict the end of the effectiveness of the deodorizer by changing the color of the indicator. Granular activated charcoal is generally used as a deodorizer in refrigerators, but the only way to predict when the deodorizer loses its effectiveness is to replace it. Because of this, I was able to know the appropriate time to replace the deodorizer.Usually, the company should use their experience to determine the appropriate time, and as a result, the deodorizer was not replaced even though it was still effective.・、Tari again! In some cases, inconveniences may occur, such as having to replace the deodorizer only after a bad odor has been detected.

It works when suctioning and determining lj, but the sensitivity is low to constantly detect the basic component of ammonia in the atmosphere by leaving it in a cold room, and the identification of discoloration is different from general #L garden. However, it lacked the above-mentioned predictive function.

A mixture of an indicator of 5 or less and an acid in an amount of 3 to 140 times the amount (weight) of the indicator IIK, and an indicator of 0.02 to 140 times the amount (weight) of the indicator
This is an indicator for a well logging warehouse that carries 0.2% (weight) of K.

を可能にしたものである。Such an indicator is made by selecting an indicator that is sensitive to basic substances, increasing its sensitivity by adjusting the combination ratio of acid and 0fIL, and combining a hydrophobic delicate base material as a carrier. This improves the distinguishability of discoloration, thereby making it possible to easily predict when the deodorizing agent will lose its effectiveness.

れて使用すると感度が低下するという欠点をもつ。If the carrier (substrate) is receptive, the basic color tone is likely to change due to moisture in the well logging warehouse, making it difficult to identify discoloration. On the other hand, if the carrier is a non-wettable fiber, it cannot be supported tightly.
Although grain size may be considered, these are disadvantageous because they do not have regular shape. ◎When adhering to a shaped object with a primary adhesive to give constant YII property and fixation, the adhesive changes color due to acid, and it also becomes uniform. - It is difficult to adhere properly, and it is also difficult to identify discoloration due to the background color of the solid substance. Also, consideration must be given to the possibility of shedding. In addition, a single grain of material has the disadvantage that sensitivity decreases when it is used in a glass tube.

In particular, acrylic fibers have good affinity and color development with the indicator, and can evenly support the indicator. As for the form of the fibers, WIt and - are preferred.

体からなるアクリル繊維が好ましい。Phosphoric acid, m-gap is preferred. The indicator is mixed with this acid, and the sensitivity is adjusted depending on the amount.
The mixing ratio is 3 to 140 times the amount (weight) of the indicator. If the amount of acid is less than this, it can be recognized that the color stability is lacking.On the other hand, if the amount exceeds 140 times, the sensitivity is poor and it cannot be used. A preferable range of the amount is 60 p. In this combination, acrylic fibers made of a polymer containing 0.1 to 0.7% of an acidic base are preferred because they are excellent in color clarity, stability, and distinguishability.

２−を越えると感度が低くなる。As a method for supporting a mixture of an indicator and an acid on a carrier, immediately after the indicator, a 0.005-O, s*Oa compound solution is applied to the carrier at a squeezing rate of 100-150%, and the mixture is heated at 60°C or higher. It is best to dry and support it. If the indicator am is low, the color tone will be discernible and it will be difficult to adjust. On the other hand, if the density is high, colored spots are likely to occur. The preferred drying temperature varies depending on the carrier, but is generally a temperature higher than the second order transition point of the fiber. In the case of acrylic fibers, the temperature is preferably 80°C or higher. The indicated amount of drug relative to the carrier is 0.02-0.2% (weight), 0.02%
If the color is less than 0.0, the color becomes one color or blurred, making it difficult to distinguish.
If the value exceeds 2-, the sensitivity decreases.

The @0.01-impregnated knitted fabric A (4) was faint in color and lacked clarity in color tone due to the ground color of the fiber itself. A discoloration test was performed on the 0.1- and 0.3-coated pots in the seven-day refrigerator of Example 1, and the results were as follows (F41, A (81)
is outside the present invention) 0 turtle 2 front east, this indicator A (51, /16 (61
The results of testing in the model cold mouse chamber in combination with Adhesive B were as follows.
