Hydroxypropyl Cellulose as Binder for Ceramic Products

Product Introduction Introduction of Hydroxypropyl Cellulose Odorless and tasteless, flammable, thermoplastic. Dissolves in water to form a transparent to milky white viscous colloidal solution. Soluble in ethanol, insoluble in ether, high degree of substitution is also insoluble in alcohol. Insoluble in water above 38℃. Physical and chemical properties of Hydroxypropyl Cellulose Appearance: white or off-white powder Granularity: 100 mesh, passage rate more than 98.5%; 80 mesh, passage rate 100% Carbonization temperature: 280-300°C Visual density: 0.25-0.70/cm3 (usually around 0.5g/cm3) Specific gravity: 1.26-1.31 Color change temperature: 190-200℃ Surface tension: 42-56dyn/cm (2% water soluble) Solubility: 1, dissolved in water: add Hydroxypropyl Cellulose slowly into the vigorously stirred water until it is completely dissolved, if all the material is added it will be difficult to dissolve; take 20-30% of the predetermined amount of water and heat it up to above 60℃,…
