Description
Известны противопригарные покрыти , примен емые дл окраскп фор.м п стержпей, в которых в качесгве oiTieynopnoro паполпител примен ют графит, циркон, магиези .Nonstick coatings are known, which are used for coloring form p rods, in which graphite, zircon, and magic are used as the oiTieynopnoro papolitel.
Однако такие иокрыти оказываютс малоэффектпвпымп при изго1ов;1еппи стержпей дл т желых отливок (весом более 10 г). Мпогие из примеп е.мых огпеупорпых паполпителеп дефицитны и дороги.However, such coatings have little effect on the fabrications; 1ppi rods for heavy castings (weighing more than 10 g).
