SU40854A1 - The method of preparation of the composition for washing the forms used in the vulcanization of rubber products - Google Patents

Description

The proposed method aims to prygoto. The effect of the composition for washing the odds used in the vulcanization of rubber products.

Molds used in the rubber industry for vulcanization of rubber products1 have fallen into disrepair after short use, as the formulations used to wash the forms so far have come into contact with the rubber mass and resulted in the formation of splitting layers and growths. The finished products, vulcanized in such forms, are hardly extracted from the latter and, moreover, have an ugly surface, which significantly reduces their selling price. For these reasons, forms are often replaced with new ones. Steel or lead forms are commonly used in the rubber industry. Steel forms, although they serve relatively long lead, but they are very expensive and lose their full value after they are out of order, while lead forms can be updated through spillover. However, this advantage does not have any particular values due to non-arrpc (c service, meaning BKtx metal losses during overflow, as well as a large amount of time to work.

The author of the present invention has established that the use as a composition for washing the forms of sugar or dextrin solutions individually or mixed with each other allows the forms to be used for almost an unlimited time, since in an atom case the deposits and growths do not accumulate on the forms and the shape remains mirror smooth Vulcanized in such forms, the products acquire a bright surface and are easily removed from the mold.

Example 1. About 100 tons of sugar are dissolved in 100 liters of water and the resulting solution is doused in forms.

Example 2: B 100 liters of water dissolve 1 ton of sugar and about 0.5 L of dextrin. The solution is used in the same manner as in the pref. .1.

Depending on the type of sugar-like body, the desired result can be modified.

Even better results can be achieved if the above solution is not applied directly to the form, but rather to create on it an additional layer 2 -

. ,one; : ..,. , ,

Mftflot hot form liquid alkaline solution of silicates. When a solution of silicates evaporates on the form, a thinnest smooth, stable layer is formed on which a thin layer of sugar is applied or pulverized.

The form may appear in work without renewing the lower limb during the course of further training for 6 days - time.

An alkaline silicate solution is prepared by dissolving 7 liters of water glass in 100 liters of water.

Subject of pateta.

1. The method of washing forms, used in the vulcanization of rubber products, separately by the fact that for washing used sugar and dextrin separately or mixed with each other.

.2. Reception -.- perform the method. 1, characterized in that a polyvinyl chloride silicate solution is used as a nanofixed on the shape of the lower layer, and a solution of sugary substances is applied on top of the lower layer.
