<p>The composition of leakage preventing agent for heating pipe is prepared by (1) mixing 20wt% of iron oxide, 45wt% of coffering levee with chip type for preventing leakage, 15wt% of iron content, 10wt% of cement powder and 10wt% of watertight agent, (2) injecting directly the mixture to heating hot water circulated. Therefore, the composition of heating pipe automatically forms water film for partially preventing leakage any prevents leakage situation.</p> |
