JPS5879158A - Method and apparatus for measuring quantity of oil attached to fiber - Google Patents

Abstract

PURPOSE:To measure the quantity of harmless oil attached to fiber quickly and at a high accuracy by injecting a very small amount of a specified liquid washed out to an equipment based on a total carbon amount measuring device. CONSTITUTION:When a desired amount of carbon-containing material dispersed in water is injected into a burning tube 5, carbon elements are turned to carbon dioxide during the passage through a catalytic bed heated up to a high temperature while a large amount of steam is retained into a drain pot 6 as liquid via an outlet 52. Then, the carbon dioxide and the gas not retained in the pot are introduced to a carbon dioxide detector 8 comprising a non-dispersion type infrared analyzer through a two-way solenoid valve 7. Electrical signals outputted from the analyzer are displayed and printed as total carbon amount and quantity of oil calculated by a predetermined desired formula through a memory arithmetic display printer 14.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for delicately measuring the amount of oil containing carbon elements.

Conventionally, 1 lll of oil 11;
The remaining amount after removing the organic solvent from the outside of the solution after washing out with a solvent was used.

But that's why! 4 (Precepts>jl method icJ washing with organic solvent 111 for a long time lJ,,iL,

It was.

However, the above method requires a sample amount ranging from several grams to one to several grams, and has the drawback of requiring a large amount of time, labor, and resource loss.

It is well known that in recent years, these organic solvents used in VC have caused a big problem in contaminating the natural world, including humans. Father, Occupation 1-1) Even when using 4-11, the regulations of industrial health management 1 are often 6-, ㅅ, &.

The purpose of the present invention is to improve the drawbacks of the conventional technology by using water that is harmless to the human body (detailedly d distilled water) or water without using solvents. 1-Ingredient 2 The surfactant-containing liquid (■+extract liquid) is used to wash out the fiber A-1 oil content by a very small amount of sample (fiber), and it is washed out using a device based on a total carbon meter measuring device. The present invention aims to provide a faster, more accurate, and non-hazardous method and apparatus for measuring oil deposits (4141).

The structure of the present invention which achieves the second object is to apply the oil containing the carbon element to the fiber in the form of an aqueous dispersion or Take out 11"1. of aqueous solution and use it as a sample liquid. Pour the sample liquid into a total carbon content 4111 measuring device and measure the total carbon content. This is a method of measuring the amount of oil adhering to fibers by determining the amount of oil adhering to the fibers from a calibration formula.

Further, a total carbon amount measuring device, a device for feeding an aqueous dispersion or aqueous solution sample liquid of an oil containing carbon elements attached to the fiber 1 to the total carbon amount measuring device, and a 61 for the total carbon amount.
In response to the electrical signals generated from the carbon oxide detection device installed in the device, I made an overview.

The relationship calibration formula between the oil content and total carbon that has been previously determined is memorized and set as a calculation block in the calculation device, and when the total carbon content (TC value) of the sample liquid is input, the oil content is Display and print as quantity.

In the second example, the amount of sample fiber exceeds 0.4 grams, but if the amount of sample fiber ## in the above example J = J, then the amount of sample in Example 2 is 04 grams and the amount of water in the example 2
