B) liquid citric acid (50%)/7.0 "kelzan"/0.4 sodium hydroxide (50% sol'n.)/4.5 C) "miranol" J2M/8.0 water/78.9 A) "veegum" T/1.2
配制方法:
prepare part A by slowly adding "veegum" T and "kelzan" to the water. continue agitating until smooth dispersion is obtained. prepare part B (trisodium citrate) by adding the citric acid to a separate tank and neutralizing it with the sodium hydroxide solution. the neutralization should be done slowly and continuously under agitation, as the reaction is highly exothermic. add part B to part A, and finally part C. the formulation has the consistency of a fluid gel. it may be used in either warm or cold ovens. the spraying should be done at distance of from 10-15 in. and clean by wiqing after at least 10 min of interaction time.
