Description

II

Изобретение относитс  к составам смазок дл  форм в производстве бетонных изделий.The invention relates to formulations for molds in the manufacture of concrete products.

Известна .смазка дл  форм, включающа  известковый компопент.Known lubricant for molds, including limestone component.

Однако при использовании этой смазки поверхность получаемых изделий низкого качества .However, when using this lubricant, the surface of the resulting products is of poor quality.

Цель изобретени  - замедление схватывани  формуемых изделий Б поверхностных сло х.The purpose of the invention is to slow down the setting of molded articles B of the surface layers.

Это достигаетс  тем, что смазка содержит в Качестве известкового компонента известковое молоко и дополнительно 37-39%-лый водный раетвор формальдегида при следующем соотношении компопептов, в %:This is achieved by the fact that the lubricant contains, as a lime component, lime milk and an additional 37-39% water solution of formaldehyde in the following ratio of compoppets,%

Известковое молоко75-95Lime milk75-95

Формальдегид5-25Formaldehyde 5-25

В результате взаимодействи  формальдегида с известью в смеси образуютс  соединени , замедл ющие схватывание минерального в жущего .As a result of the interaction of formaldehyde with lime, compounds are formed in the mixture, which slow down the seizure of the mineral in the binder.

Способ приготовлени  смазки заключаетс  в €ледуюп1;ем. В предварител1зпо приготовлеппое известковое молоко (150-180 г гашенной известп 50%-ной влажности) ввод т водный 37-39%-ный раствор формальдегида (формалин ).The method of preparation of the lubricant consists in the following; i. An aqueous 37-39% formaldehyde solution (formalin) is introduced into the pre-cooked lime milk (150-180 g of slaked lime at 50% humidity).

Смазку иапос т на форму вручную кист ми и.чп с помощью распылителей.Lubricate the mold onto the mold manually with a brush using a spray bottle.

Пред м е т и з о б р е ч- е и и  PREPARATION AND RESULTS

Смазка дл  форм в производстве бетонных изделий, включающа  известковый компонент, отличающа с  тем, что, с целью замедлени  схватывани  формуемых изделий в поверхностных сло х, она содержит в качестве известкового компопеита известковое молоко и дополпительно 37-39%-ный водный раствор формальдегида при следующем соотношепии компонентов, об. %:Mold lubricant in the manufacture of concrete products, which includes a lime component, characterized in that, in order to slow down the setting of molded products in the surface layers, it contains lime milk as a lime compoteite and additionally 37-39% aqueous formaldehyde solution at the following ratio of components, about. %:
