Definition Conductivity, also known as specific conductance, refers to the ability of a material or solution to conduct electric current. It is the reciprocal of resistivity and is commonly represented by the symbol κ (kappa). In chemical and process engineering,…
Definition Water (H₂O) is a fundamental chemical substance composed of hydrogen and oxygen. It exists widely in nature and industrial systems in liquid, solid, and gaseous states. In chemical and process engineering, water is not only a natural resource but…
Overview In chemical and process industries, hazard analysis and risk assessment are two foundational elements of process safety engineering. They are used to systematically identify potential hazards in industrial systems and evaluate the associated risks to ensure safe design, operation,…
Definition New energy materials refer to a broad class of functional materials used in energy conversion, storage, and utilization systems that support renewable and low-carbon energy technologies. Unlike conventional industrial materials, new energy materials are designed to enable or improve…
Definition Degradable plastics are polymer materials designed to undergo structural breakdown under specific environmental conditions such as heat, moisture, oxygen exposure, or microbial activity. Unlike conventional plastics, which remain chemically stable for long periods, degradable plastics are engineered to reduce…
Definition Renewable feedstock refers to raw materials that originate from renewable or recoverable sources and can be reintroduced into industrial production systems. Unlike virgin fossil-based feedstocks, renewable feedstocks are derived from waste streams, recycled materials, or biomass-based resources that can…
Choosing among PLA manufacturers requires more than comparing resin prices or production capacity. Industrial buyers should evaluate grade availability, processing compatibility, batch consistency, technical support, and supply reliability. A practical selection path is: Application → Required Properties → PLA Grade…
간단히 말해, 고성능 폴리머 생산을 연속 공정으로 전환하는 것은 단순히 배치 반응기를 연속 반응기로 교체하는 것만큼 간단하지 않습니다. 진정한 과제는 반응 동역학, 재료 점도, 발열, 휘발성 물질 제거, 공정 제어 등을 조화롭게 맞추는 데 있습니다…
충전탑 대 트레이탑 충전탑과 트레이탑 모두 증류 및 흡수와 같은 기체-액체 물질 전달 공정에 널리 사용됩니다. 가장 적합한 탑을 선택하려면 원료의 물성, 운전 조건, 장비 제작 등 여러 요소를 평가해야 합니다,…
