<P>PROBLEM TO BE SOLVED: To provide a material or a scale inhibition method for inhibiting generation of aluminosilicate scale in an industrial process having alkaline process stream, e.g., pulp producing process stream. <P>SOLUTION: A polymer with at least 0.5 mol% of a side chain or a terminal group containing -Si(OR'')<SB POS="POST">3</SB>(where R'' is H, an alkyl group, Na, K, or NH<SB POS="POST">4</SB>) is added to an alkaline process stream. Accordingly generation of aluminosilicate scale on equipment surfaces such as an evaporator wall surface and a heating surface is reduced or prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
