Abstract : The present situation of production technology, application technology and market development of hydroxypropyl methylcellulose (HPMC) at home and abroad is reviewed. At present, developed countries such as Europe and the United States more adopt the gas-phase process to produce HPMC, whic
READ MORE Abstract: Hydroxypropylmethylcellulose (HPMC) is used as the mother material. Using succinic anhydride as esterification agent and anhydrous sodium acetate as catalyst, hydroxypropyl methylcellulose succinate (HPMCS) was prepared by esterification reaction in acetic acid. By changing the reaction te
READ MORE Abstract: Compared with the tableting process after granulation, the direct compression process is the best choice for tablet production. However, due to its high performance requirements for raw materials, only a small amount of drugs can be produced by the direct compression process. . Based on th
READ MORE Abstract: As a modifier, hydroxypropyl methylcellulose solution is mixed into cement mortar to improve its toughness. The effects of water-binder ratio, concentration and content of cellulose solution on the flexural strength, compressive strength and flexural ratio of cement mortar were studied by
READ MORE Abstract: Cellulose ether is an essential additive in machine-blasted mortar. The effects of four different viscosities of hydroxypropyl methylcellulose (HPMC) on the water retention, density, air content, mechanical properties and pore size distribution of machine-blasted mortar were studied. Studi
READ MORE Resumen: Se estudió el efecto de la hidroxipropilmetilcelulosa (HPMC) sobre el estado de humedad de la masa, las propiedades de cristalización de proteínas y almidón y la estructura del gluten, y se analizó el efecto de la HPMC sobre la mejora de la calidad de consumo de los palitos de masa frita me
