Title:
DIVIDED PACKAGE OF INTERNALLY TAKING ADSORBENT AND PREPARATION THEREOF
Document Type and Number:
Japanese Patent JP2607422
Kind Code:
B2
Abstract:
PURPOSE: To suppress deformation caused by the change in the vol. of air wrapped in an internally taking adsorbent filled in a divided package by making vol. expansion coefficient at a specified temp. of the divided package wherein the internally taking adsorbent discharging a specified vol. of air per 1g during temp. elevation of a specified value is wrapped to be a specified value.
CONSTITUTION: Vol. expansion coefficient from 10°C to 30°C of a divided package wherein an internally taking adsorbent discharging 1.3-10ml air per 1g during temp. elevation from 10°C to 30°C is wrapped, is made 0-0.064ml/°C.g. The method for preparing it is that the temp. of the internally taking adsorbent is made at a temp. being 5°C higher than room temp. to 300°C and after it is filled, it is sealed or that after the internally taking adsorbent is filled in the divided package, it is sealed at the atmospheric pressure or lower. In the divided package of this internally taking adsorbent, as there scarcely exists deformation of the divided package caused by the change in the vol. of air wrapped in the internally taking adsorbent, troubles based on the change in vol. of the divided package during packaging in a box, storage and transportation of the internally taking adsorbent, can be solved.
