Description

Изобретение может быть использовано при изготовлении автоклавных строительных изделий .The invention can be used in the manufacture of autoclaved building products.

Известна смазка, включающа  машинное масло и полимерную добавку.A lubricant is known, including engine oil and a polymeric additive.

Целью изобретени   вл етс  улучшение качества поверхности изделий и увеличение теплостойкости смазки.The aim of the invention is to improve the surface quality of the products and increase the heat resistance of the lubricant.

Достигаетс  это тем, что смазка содержит машинное масло в количестве 90-96% (по весу ) и низкомолекул рный полиэтилен (воск) в количестве 4-10%.This is achieved in that the lubricant contains engine oil in an amount of 90-96% (by weight) and low molecular weight polyethylene (wax) in an amount of 4-10%.

Низкомолекул рный полиэтилен  вл етс  побочным продуктом при производстве полиэтилена низкого давлени  и состоит из полиэтилена с молекул рным весом от 4000 до 20000, воска в количестве до 45% по весу и имеет температуру плавлени  до 122°С.Low molecular weight polyethylene is a byproduct in the production of low pressure polyethylene and consists of polyethylene with a molecular weight of 4,000 to 20,000, wax in an amount of up to 45% by weight and has a melting point of up to 122 ° C.

Смазку получают в варочном котле с электрическим или другим видом подогрева, кудаLubrication is obtained in a digester with an electric or other type of heating, where

загружают куски величиной 10-15 см и маишнное масло.load pieces the size of 10-15 cm and macaunt oil.

После разогрева массы до 130°С и перемешивани  ее в течение 3-5 мин, смесь охлал дают до 80°С, и нанос т смазку на форму путем распылени  через форсунку или вручную.After heating the mass to 130 ° C and stirring it for 3-5 minutes, the mixture is cooled to 80 ° C, and the lubricant is applied to the mold by spraying through a nozzle or manually.

Смазка может быть использована в холодном виде.Lubrication can be used cold.

Поверхность готовых изделий получаетс  без повреждений и готовой под окраску.The surface of the finished product is obtained without damage and ready for painting.

Предмет изобретени Subject invention

Смазка дл  металлических форм, используемых при изготовлении автоклавных строительных изделий, включающа  машинное масло и полимерную добавку, отличающа с  тем, что, с пелью улучшени  качества поверхности изделий и увеличени  теплостойкости смазки, она содержит машинное масло в количествеLubricant for metal molds used in the manufacture of autoclaved construction products, including engine oil and polymer additives, characterized in that, with an improvement in the quality of the surface of the products and an increase in the heat resistance of the lubricant, it contains engine oil in an amount

90-96% (по весу) и низкомолекул рный полиэтилен (воск) в количестве 4-10%.90-96% (by weight) and low molecular weight polyethylene (wax) in an amount of 4-10%.
