Description
Vynález sa ’ týká zmesnáho prostriedku uvoíňovanie skrutkových spojov s komplexným účinkom na báze komerčně vyrábaných komponentov.The present invention relates to a blend release composition with complex effect based on commercially produced components.
Skrutkové spoje podliehajú va vačšine značnej korózii, a to ako vplyvom atmosféry, tak aj kvapalných a mechanických nečistot, ktorými sa v priebehu prevádzky tieto spoje zanášajú. ich uvoíňovanie je fyzicky namáhavé a značné právně, pričom často dochádza aj k znehodnoteníu závitového spoja, ale aj príslušnej konštrukčnej časti alebo dielu. Bežne používané prostriedky, ako je nafta alebo petrolej, nie sú vždy dost účinné, najma vplyvom prítomnej vlhkosti na skrutkovom spoji.Screw connections are subject to most corrosion, both due to the atmosphere, as well as to the liquid and mechanical impurities that clog these connections during operation. their loosening is physically strenuous and considerable in legal terms, and often the threaded joint, but also the respective component or part, deteriorates. Commonly used formulations, such as diesel or kerosene, are not always effective enough, especially due to the presence of moisture on the screw connection.
Podstatou vynálezu je zmesný prostriedok na uvoíňovanie skrutkových spojov na báze kvapalných uhíovodíkov, ktorý pozostáva z 85 až 98 hmot. dielov aspoň jednej ropnej frakcie s počtom uhlíkov v reťazci 9 až Ii6, s teplotou tuhnutia pod 0 °C a so začiatkom destilácie nad 50 °C, z 1 až 10 hmot. dielov etanolu a z 0,5 až 8 hmot. dielov neiónového tenzidu.SUMMARY OF THE INVENTION The present invention is based on a liquid hydrocarbon-based compounding composition comprising 85 to 98 wt. parts of at least one petroleum fraction having a number of carbons in the chain of 9 to 16, with a pour point below 0 ° C and a distillation start above 50 ° C, from 1 to 10 wt. % of ethanol and from 0.5 to 8 wt. parts of a nonionic surfactant.

č.no.
2 7 šenej vzlínavosti, zlepšenej zmáčavosti a v účinku i na zvlhnuté materiály. Naviac neposobí ani na nátěrové hmoty aplikované na kovových materiáloch. Komponenty sú cenovo nenáročné a jeho příprava spočívá len v jednoduchej homogenizácii.2 7 improved wettability, improved wettability and, in effect, on wet materials. In addition, it does not apply to coatings applied to metallic materials. The components are cost-effective and their preparation consists only in simple homogenization.
Ako ropnú frakciu je výhodné používať komerčně zmesi uhíovodíkov, aiko sú nafta, petrolej ap., alebo sa imóžu používať záměrně připravené zmesi uhíovodíkov.As the petroleum fraction, it is preferred to use commercially a mixture of hydrocarbons such as naphtha, kerosene and the like, or intentionally prepared mixtures of hydrocarbons can be used.
Na používaný etanol nie sú kladené osobitné požiadavky, okrem čo najnižšieho obsahu vody. Možno používať etanol denaturovaný prakticky 1'ubovolným denaturačným prostriedkom, keď jeho výsledná koncentrácia v prostriedku podía vynálezu bude veími nízká. Rovnako možno použiť i syntetický etanol.There are no special requirements for the ethanol used except for the lowest possible water content. Ethanol denatured with virtually any denaturing agent can be used when its final concentration in the composition of the invention is very low. Synthetic ethanol may also be used.
Z neiónových tenzidov sú najaktuálnejšie tie, ktoré majú dobré zmáčacie účinky, ako sú napr. etoxylované vyššie mastné alkoholy.Among the nonionic surfactants, the most recent are those having good wetting effects, such as e.g. ethoxylated higher fatty alcohols.
Medzi dóležité vlastnosti prostriedku podlá vynálezu patří vzlínavosť, ktorá sa odskúšava na štandardne skorodovanom materiále. Výsledky pokusov a zloženie použitého prostriedku sú uvedené v nasledujúcej tabufke:Important properties of the composition of the invention include capillary action, which is tested on a standard corroded material. The results of the experiments and the composition of the formulation used are shown in the following table:
vzlínavosť mni. min-1 petrolejcapillarity to me. min -1 kerosene
97 hmot. dielov — petrolej hmot. diel — tenzid hmot. diely — etanol97 wt. parts - kerosene mass. part - surfactant mass. parts - ethanol

7,2 hmot. dielu — tenzid 8,5 hmot. dielu — etanol7.2 wt. part - surfactant 8.5 wt. part - ethanol
Ve všetkých pokusoch ako neiónový tenzid sa použijú pre porovnateínosť výsledkoiv etoxylované vyššie mastné alkoholy (SLOVASOL SF). Pripravok je dobré aplikovatelný i na vlhké materiály.In all experiments ethoxylated higher fatty alcohols (SLOVASOL SF) were used as a nonionic surfactant for comparability. The preparation is also suitable for wet materials.
