PURPOSE:To reduce tar adhesion sharply and prevent compustion instruments or apparatus from functional reduction by adding at least one component, a reducing agent inhibiting the formation of tar or an alkaline neutralizing or saponificating the reducing agent, to the tar adhesion preventing agent. CONSTITUTION:In the mixing rate of components is expressed by weight parts, for example, the components consisting of 50 nickel oxide as an oxidation catalyst, 30 methylphenyl silicon as an additive 1, 50 alumina, silica and thinner as an additive 2 are added to tar adhesion preventing agent composed of 30 a reducing agent (Zn powder) and 30 an alkaline agent (calcium silicate). Although the additives 1 and 2 act as a bonding agent and an improving agent for coating and filming properties, respectively, both of them have the properties to increase the strength of a formed film and make it porous in addition to the sufficient heat resistance more than the temperature of the inwall of a carbureter drum. These components are mixed in a ball mill and applied to the in wall of carbureter drum by a spray. |
