Agente de Encolado AKD (Dímero de Alquil Cetena)
El dímero de alquil cetena (AKD) es un agente de encolado interno neutro y alcalino ampliamente utilizado en la producción de papel y cartón. Forma un enlace éster covalente con los grupos hidroxilo de la celulosa, proporcionando una excelente hidrofobicidad a largo plazo y retención de tinta. El AKD se suministra típicamente como una emulsión cerosa estable para facilitar su adición en el extremo húmedo.

Agente de Encolado ASA (Anhídrido Succínico Alquenílico)
CAS: 26680-54-6
El anhídrido succínico alquenílico (ASA) es un agente de encolado interno reactivo ampliamente utilizado en sistemas de fabricación de papel neutro y alcalino. Proporciona excelente hidrofobicidad al papel y cartón, asegurando fuerte resistencia al agua e imprimibilidad. El ASA reacciona covalentemente con las fibras de celulosa, proporcionando un desempeño de encolado duradero incluso a niveles de dosificación bajos.

Almidón Oxidado (Grado para Encolado Superficial)
CAS: 65996-62-5
El almidón oxidado es un almidón modificado químicamente producido por oxidación con hipoclorito, lo que le confiere menor viscosidad y mejores propiedades formadoras de película que el almidón nativo. Se utiliza ampliamente como agente de encolado superficial aplicado en la prensa de encolado o en la prensa de película de las máquinas papeleras. El almidón oxidado mejora la resistencia superficial, la imprimibilidad y la lisura del papel y cartón.

Agente de Encolado Superficial Hidrofóbico
Los agentes de encolado superficial hidrofóbicos son formulaciones poliméricas aplicadas en la prensa encoladora o prensa de película para impartir repelencia al agua y resistencia a líquidos a las superficies de papel y cartón. Están basados en química de estireno-acrilato, estireno-anhídrido maleico o emulsión de poliuretano, proporcionando una resistencia al agua, valores Cobb y resistencia a la grasa superiores en comparación con el encolado únicamente con almidón. Estos agentes son esenciales para aplicaciones de papel para embalaje, papel en contacto con líquidos y papel de grado alimentario.

Enzima de Desencolado (Alfa-Amilasa)
CAS: 9000-90-2
La alfa-amilasa es un agente enzimático de desencolado termoestable que hidroliza los agentes de encolado a base de almidón sobre tejidos de algodón y mezclas de algodón con alta eficiencia y mínimo daño a la fibra. Trabaja en condiciones suaves (50–70 °C, pH 6–7), eliminando la necesidad de desencolados oxidativos o alcalinos agresivos. Ampliamente utilizado en líneas continuas modernas de desencolado para camisería de algodón y denim.

Frequently Asked Questions
▶AKD vs ASA — which internal sizing agent should I choose?
Choose AKD for stable neutral/alkaline systems with slower sizing development; choose ASA when fast sizing speed and high-filler furnishes are needed, but ASA requires on-site emulsification.

▶Why does rosin sizing require alum, and what are the limitations?
Alum (aluminum sulfate) precipitates rosin soap onto fibers as aluminum rosinate and provides the electrostatic fixation needed at acidic pH. The main limitation is the requirement for acidic conditions (pH 4–5.5), which degrades paper over decades.

▶What is the Hercules Sizing Test (HST) and what values are typical?
HST measures the time (in seconds) for a standard dye solution to penetrate through a paper sample — higher seconds = better sizing. Copy paper targets HST > 60 s; packaging grades vary from 5–30 s.

▶How does carbon fiber sizing affect composite mechanical properties?
Sizing improves fiber-matrix interfacial shear strength (IFSS) by 20–50%, preventing delamination under flexural and interlaminar shear loading; it also protects fiber filaments during handling and winding.

▶What is the difference between surface sizing and internal sizing?
Internal sizing adds chemical agents to the wet-end furnish so they become permanently bonded in the fiber network; surface sizing applies a film at the size press to improve surface strength and printability without penetrating the sheet core.
