Hydroxypropyl methylcellulose can adjust the residence time and kneading state

- Aug 21, 2014 -

Adhere to the quality of survival, innovation and business development purposes
The crude reaction product of hydroxypropyl methyl cellulose can be used for continuous kneading apparatus of this product can be used includes a groove (roller) and the blade, or a double-pole single pole unit, etc., from the viewpoint of excellent kneading , preferably double-pole type device. With this arrangement of the combination of built-in blades changes, the residence time can be adjusted, and kneading state. Moreover, the length of the blade groove can be used to diameter ratio L / D of about 5-13 in a continuous kneading apparatus is. When the ratio is less than 5, and has not been completely dissolved in it is discharged; while more than 13, because of excessive kneading leaving the lower degree of polymerization products, and products yellow deepened as a result of deterioration. The shape of the blade, the blade through a combination of a variety of plate-type and spiral type, etc., can be adjusted kneaded state. Moreover, continuous kneading devices can either use one, it can be divided into dissolved and neutralized with two.
   Shape retention: Compared with other water-soluble polymers, aqueous solution of the product has a special viscoelastic properties. It is added to improve the ability of the ceramic article does not change the shape of the extrusion.
Lubrication: Add this product to reduce the friction coefficient and improve the extrusion of ceramic products, cement products lubricity.
Film: The product can generate strong flexible, transparent sheet, good oil resistance properties ester
   Warmly welcome all customers at home and abroad to discuss cooperation, win-win development!
