Описание (английский):

The determination method applies to plasticized cellulose acetate in any form, such as moulding material, sheet, manufactured articles. Conversion of the plastizised sample to a film, prepared by dissolving and casting, and subsequent extraction by ethylether in a Soxhlet apparatus. Removal of the ether by heating under vacuum and weighing the residual matter.

Overview

SIST ISO 1875:1996 specifies a standardized method for determining the percentage of matter extractable by diethyl ether from plasticized cellulose acetate. This international standard applies to plasticized cellulose acetate in all its forms, including moulding material, sheets, and finished articles. By outlining a reliable extraction and quantification process, this standard ensures accurate identification of extractable substances such as plasticizers present in cellulose acetate plastics.

Key Topics

Scope: Applicability to all forms of plasticized cellulose acetate, from raw moulding materials to manufactured articles.

Principle: Conversion of a sample into film by dissolving and casting, followed by extraction of soluble matter using diethyl ether in a Soxhlet apparatus.

Extraction Method: Use of diethyl ether as the solvent in a Soxhlet extraction setup to isolate and determine extractable matter, primarily plasticizers.

Solvent Removal: Removal of diethyl ether by vacuum heating, ensuring accurate residue weight measurement for analysis.

Expression of Results: Calculation of the ether-extractable content, expressed as a percentage by mass based on the residue after extraction and drying.

Applications

SIST ISO 1875:1996 supports quality control, research, and compliance in the plastics industry, offering practical value in the following areas:

Material Quality Assurance: Ensures the uniformity and reliability of plasticized cellulose acetate by quantifying removable additives, supporting manufacturers in delivering consistent products.

Regulatory Compliance: Assists producers in meeting regulatory limits on plasticizer content and other additives, vital for industries where product safety and consistency are critical.

Process Optimization: Provides insights into material composition for optimizing processing parameters and improving end-products’ performance in fields such as packaging, automotive, and consumer goods.

Product Development: Supports research and development teams in evaluating new plasticizer systems or alternative additives by allowing precise measurement and comparison of extractable matter.

Troubleshooting: Identifies potential issues related to product failure or non-uniformity stemming from excessive extractable matter, facilitating root-cause analysis and corrective action.
