What is ISO 2028:2015-Synthetic rubber latex — Preparation of dry polymer?
ISO 2028:2015 specifies a method for the preparation of dry polymer from synthetic rubber latex by two different methods: coagulant addition and centrifugation. The method described in ISO 2028 is applicable to the preparation of dry polymer from synthetic rubber latex of any kind.
The coagulant addition method involves the addition of a coagulant to synthetic rubber latex to destabilize the colloidal system, causing the rubber particles to agglomerate and form a clot. The clot is then washed and dried to produce the dry polymer.
The centrifugation method involves the separation of the synthetic rubber latex into two fractions using a centrifuge. The resulting coagulum is then washed and dried to produce the dry polymer.
This standard specifies the requirements for the synthetic rubber latex used in the preparation of dry polymer and provides guidance on the preparation of the dry polymer. It also specifies the properties that the dry polymer should possess. Including particle size, moisture content, and ash content.
It is intended for use by producers and users of synthetic rubber latex, including manufacturers of products that use synthetic rubber latex as a raw material.
Requirements of ISO 2028:2015
ISO 2028:2015 specifies the requirements for the preparation of dry polymer from synthetic rubber latex using coagulant addition and centrifugation methods. The standard provides guidelines for the preparation of the dry polymer. As well as specifications for the synthetic rubber latex used in the process.
Some of the key requirements outlined in this standard include:
Synthetic rubber latex: The synthetic rubber latex used in the preparation of the dry polymer should be of high quality and should meet the requirements specified in the standard. The standard specifies the minimum dry rubber content, pH value, and total solids. Also, other physical and chemical properties that the latex should possess.
Coagulant: The coagulant used in the coagulant addition method should be suitable for the synthetic rubber latex being used and should be added in the correct quantity to ensure effective coagulation. The standard provides guidance on the type and quantity of coagulant to be used.
Centrifugation: The centrifugation method should be carried out using appropriate equipment and under conditions that ensure effective separation of the synthetic rubber latex into two fractions. The standard specifies the speed and time of centrifugation, as well as the acceptable moisture content of the resulting coagulum.
Drying: The dry polymer should be dried to a specified moisture content using appropriate methods. The standard provides guidelines for the drying process and specifies the acceptable range of moisture content for the dry polymer.
Properties: The dry polymer should possess certain properties, such as particle size, ash content, and moisture content, that are specified in the standard. Thus, the standard provides methods for measuring these properties and specifies the acceptable ranges for each.
Benefits of this standard:
ISO 2028:2015 specifies the procedures for the preparation of dry polymer from synthetic rubber latex. The benefits of following this standard are:
Consistency: By following the standard procedures, the dry polymer obtained will be consistent in quality and properties.
Quality control: The standard provides guidelines for quality control during the preparation process. Which ensures that the dry polymer meets the required specifications.
Efficiency: The standard procedures are optimized to provide maximum efficiency in terms of yield and energy consumption.
Safety: The standard provides guidelines for safe handling of synthetic rubber latex. Which can be hazardous if not handled properly.
Compatibility: The dry polymer obtained by following the standard procedures will be compatible with other materials used in the manufacture of rubber products, ensuring optimal performance of the final product.
Who needs ISO 2028:2015?
ISO 2028:2015 is primarily intended for use by manufacturers and suppliers of synthetic rubber latex. Who prepare dry polymer for use in the production of rubber products. Therefore, this includes companies that produce gloves, condoms, adhesives, foam, and other products made from synthetic rubber latex.
It may also be useful for organizations involved in research and development of synthetic rubber latex and related products.
