Frequently Asked Questions (FAQs)
1. What is the difference between a binder and a portfolio?
A binder is a collection of documents that are frequently used and need to be easily accessible. On the other hand, a portfolio is typically a professional collection of work or documents that showcases skills, achievements, or projects. While both use binders, the difference lies in the purpose and content of the documents they hold.
2. Can a binder be a portfolio?
Yes, a binder can serve as a portfolio. A multi-functional portfolio binder is useful for professionals like lawyers, business elites, successful individuals, and college students. It allows them to manage documents efficiently and handle various tasks with ease.
3. What are the 4 types of binders?
The classification of binders is based on their chemical resistance and field of use. The four types include non-hydraulic binders (e.g., gypsum, air-cements, magnesia, hydrated lime), hydraulic binders (e.g., Roman cement, portland cement, hydraulic lime), acid-resistant binders (e.g., silicon fluoride cement, quartz cement), and autoclavable binders (harden at high temperatures and pressure). Each type has its specific applications.
4. Which is better D-ring or O-ring binder?
The choice between D-ring and O-ring binders depends on the project's size and needs. O-rings are more common but have a lower sheet capacity.
