Abstract

The invention relates to a timber treating with oil-based antiseptic. The problem to be solved: to improve the efficiency of wooden sleeper treating and preventing a wooden sleeper from biological decaying by decreasing antiseptic used. Dried-up wooden sleepers are put into an autoclave under pressure of 0.2 - 0.5 MPa for 10 to 15 minutes. After decreasing the pressure until 0.1 MPa the autoclave is filled with the shale oil heated to a temperature of 90 to 115 degrees C. Then the pressure is increased to 1.2 - 1.6 MPa, and after 80 - 200 minutes the wooden sleepers are drained for 20 to 40 minutes under reduced pressure of 0.06 to 0.09 MPa. By draining the wooden sleepers the air pressure is increased up to 0,1 MPa and the free shale oilis discharged.

Description

Medinių pabėgių įmirkymo gylį nustato sekančiai. Bandinius iš įmirkyto pabėgio ima gręžiant tuščiaviduriu grąžtu, kurio vidinis skersmuo 5 mm. Gręžimo gylis 10 mm.The depth of impregnation of wooden sleepers is determined as follows. Samples of impregnated sleepers shall be taken by drilling a hollow drill with an inside diameter of 5 mm. Drilling depth 10 mm.

Pareikštas medinių pabėgių įmirkymo būdas užtikrina tolygų kokybišką įmirkymą ir 3-5 mm įmirkymo gylį. Tokio įmirkymo gylio pakanka, kad mediniai pabėgiai būtų efektyviai apsaugoti nuo biologinio suirimo. Efektyvų pabėgių įmirkymą ir nusausinimą sąlygoja atitinkamai parinktas oro slėgio keitimas autoklave. Be to, pareikštu būdu įmirkant medinius pabėgius, antiseptiko - skalūnų alyvos sunaudojama mažiau. Neįsigėrusi į pabėgius skalūnų alyva tinkama pakartotiniam panaudojimui.The state-of-the-art impregnation method for wooden sleepers ensures consistent quality impregnation and a depth of 3-5 mm. This depth of impregnation is sufficient to effectively protect wooden sleepers from biodegradation. Effective impregnation and drainage of sleepers is due to the appropriately selected air pressure change in the autoclave. In addition, the claimed method of impregnating wooden sleepers reduces the use of antiseptic-shale oil. Shale oil, not absorbed by sleepers, is suitable for reuse.

Išradimo apibrėžtisDefinition of the Invention 1. Medinių pabėgių įmirkymo būdas, panaudojant aliejinius antiseptikus, besiskiriantis tuo, kad išdžiovintus iki ne daugiau kaip 30 % drėgnumo medinius pabėgius sudeda į autoklavą, esant 0,2-0,5 MPa oro slėgiui ir po 10-15 min., sumažinus oro slėgį iki 0,1 MPa, autoklavą užpildo pakaitintu iki 90-115 °C antiseptiku, po to pakelia slėgį iki 1,2-1,6 MPa ir po 80-200 min., sumažinus oro slėgį iki 0,06-0,09 MPa, pabėgius sausina 20-40 min., o juos nusausinus, pakelia oro slėgį iki 0,1 MPa ir išleidžia neįsigėrusį į pabėgius antiseptiką.1. A method of impregnating wooden sleepers using oil-based antiseptics, characterized in that the dried wooden sleepers are dried in an autoclave at a humidity of not more than 30% at an air pressure of 0.2-0.5 MPa and after 10-15 min. pressures up to 0.1 MPa, fill the autoclave with heated antiseptic up to 90-115 ° C, then raise the pressure to 1.2-1.6 MPa and after 80-200 minutes, reducing the air pressure to 0.06-0.09 MPa dehydrates for 20-40 minutes after escaping and, when dehydrated, raises air pressure to 0.1 MPa and releases non-absorbent antiseptic. 2. Medinių pabėgių įmirkymo būdas pagal 1 punktą besiskiriantis tuo, kad medinių pabėgių įmirkymui kaip antiseptiką naudoja skalūnų alyvą.2. A method for impregnating wooden sleepers according to claim 1, wherein shale oil is used as an antiseptic for impregnating wooden sleepers.
