Description

Известны краски, содержащие в своем составе асбест и бентонит. Предлагаема  асбесто-бентонитова  краска позвол ет увеличить стойкость формы и предупреждает образование отбела «а чугунных трубах , отливаемых в кокиль.Known paints containing asbestos and bentonite. The proposed asbestos-bentonite paint allows to increase the durability of the mold and prevents the formation of chill on cast iron pipes, cast in a chill mold.

В состав краски вход т (по весу) 20,2% асбестового порошка, 9,3% бентонита и 70,5% воды.The paint contains (by weight) 20.2% asbestos powder, 9.3% bentonite and 70.5% water.

Предлагаемую теплоизол ционную и противопригарную краску изготавливают следующим образом. Асбест любого сорта прокаливают в течение 20-30 мин при 850-900°, измельчают и просеивают через сито 0,2-0,3 мм. Бентонит с бентонитовым числом (способность к гелеобразованию ) не менее 80 единиц просушивают при 110-120°, затем размельчают и просеивают через такое же сито. Асбест и бентонит смешивают в нужйых пропорци х и разбавл ют водой.The proposed insulating and nonstick paint is made as follows. Asbestos of any kind is calcined for 20-30 minutes at 850-900 °, crushed and sieved through a sieve of 0.2-0.3 mm. Bentonite with a bentonite number (ability to gel) at least 80 units are dried at 110-120 °, then crushed and sieved through the same sieve. Asbestos and bentonite are mixed in the required proportions and diluted with water.

Полученна  краска должна иметь плотность 1,2-1,25 г/слЛ Она наноситс  на внутреннюю поверхность кокил , подогретого до 250-300°, методом распылени  с толщиной сло  0,2-0,3 мм за 10-15 мин до заливки металла.The resulting paint should have a density of 1.2-1.25 g / sl. It is applied to the inner surface of the mold, heated to 250-300 °, by spraying with a layer thickness of 0.2-0.3 mm 10-15 minutes before pouring metal .

Предмет изобретени Subject invention

Асбесто-бентонитова  краска, наносима  пульверизатором «а металлическую форму, с целью предотвращени  отбелачугунных отливок, отличающа с  тем, что в ее состав вход т 20,2% асбестового порошка, 9,3% бентонита и 70,5% .воды.....;Asbestos-bentonite paint applied with a spray gun and a metal form to prevent white iron castings, characterized in that it contains 20.2% of asbestos powder, 9.3% of bentonite and 70.5% of water ... ..;
