Curing agent for amine-formaldehyde resins and method of production of the curing agent for amine-formaldehyde resins

摘要

a sealant for resins aminowo - formaldehydowych containing ammonium nitrate ammonium bisulphite, mixed with urea, ammonium sulphate and sodium sulphite is characterised by that it contains monoammonium phosphate and diammonium phosphate jednoamonowy favourably of 0.2 - 2% by weight . 0.8% by weight.process for the production of utwardzacza for resins aminowo - formaldehydowych through mutual dissolution of ammonium bisulphite, ammonium nitrate mixed with urea, ammonium sulphate and sodium sulphate is that these compounds are introduced to utwardzacza in maximum concentration ch arising from these salt solubility in water at a temp. 20 st.celsius, and ammonium sulphate at a concentration of 20 - 42% favourable 40% is added to utwardzacza in the form of aqueous solution with the addition of phosphate dwuamonowego favourably jednoamonowego of 0.2 - 2% by weight preferably 0.8% by weight, or in the form of roztworzonej in waste water of temp. above 105 degrees fahrenheit. sci.desalination steam boiler of electric przewodnou015bciu0105 the 2000 - 3000 s / m and ph above 9.0. it is beneficial to utwardzacza ammonium nitrate mixed with urea as a liquid fertilizer for agriculture at max 80% by weight.
