Description
Vynález sa týká spósobu odstranovania vrstvy zosietovanýoh polyakrylnitrilových kaučukov z výrobného zariadenia, podláh, stien, kovových častí a zásobníkov,The invention relates to a method for removing a layer of cross-linked polyacrylonitrile rubbers from a manufacturing plant, floors, walls, metal parts and containers.
V súčasnosti sa zaschnuté a zosietené polyakrylnitrilové kaučuky odstraňujú z výrobného zariadenia ručnýra zoškrabáváním filmu čiastočne naleptaného perchlóretylénom. Velmi často třeba zosietené polyakrylnitrilové kaučuky odstraňovat aj z podlah, stien, kovových častí, zásobníkov a pod·Presently, dried and crosslinked polyacrylonitrile rubbers are removed from the toweling machine by scraping a film partially etched with perchlorethylene. Very often, crosslinked polyacrylonitrile rubbers should also be removed from floors, walls, metal parts, containers, etc.
Odstraňovanie zaschnutých a zosietených polymérov je velmi namáhavé a navýše práca s perchlóretylénom je pre mužov riziková a pre ženy zakázaná·Removal of dried and crosslinked polymers is very strenuous and, in addition, working with perchlorethylene is a risk for men and forbidden for women ·
Odstránenie vrstvy zosietených polyakrylnitrilových kaučukov možno vyriešit spósobom podlá vynálezu, ktorého podstata spočívá v tom, že před zosietením polyakrylnitrilových kaučukov sa na exponované miesta nanesie vrstva grafitu o hrúbke 2,10 až 4·10 mm a po zosietení sa vrstvy mechanicky odstránia,The removal of the crosslinked polyacrylonitrile rubber layer can be achieved by the method according to the invention, which consists in applying a layer of graphite having a thickness of 2.10 to 4 · 10 mm to the exposed areas and mechanically removing them after crosslinking,
Kryštálová mriežka tuhy vytvoří medzivrstvu znižujúcu přilnavost polyakrylnitrilových kaučukov aj po zosietení a tým, že zvyšuje súčasne povrchové napátie, porušuje celistvost filmu, takže ho možno lahko mechanicky odstranit· Navýše ide o látku lahko dostupnú, lacnú a nie zdraviu škodlivú.The lead crystal lattice forms an interlayer that reduces the adhesion of polyacrylonitrile rubbers after crosslinking, and by increasing the surface tension at the same time, breaks the film's integrity so that it can be easily removed mechanically.
PříkladExample
Pokusy sa robili na kovových súčiastkach a na podlahovině z plastbetonu.Attempts were made on metal parts and on plastic concrete flooring.
Na vzorky - ocelové uholníky a podlahovinu sa nanieslaThe samples - steel angles and flooring were applied
232 039 vrstva grafitu natretím a potem sa štetcom naniesol Hycar 2600x138 (emulzia polyakrylnitrilového kaučuku)· Po nanesení niekolkých v stiev Hyoaru 2600x138 o celkovej hrúbke 3.10~žni sa vzorky vysušili v sušiarni pri teplote 120 až 140 °C· Po vysušení sa vrstva zcsieteného rozpukala a velmi lahko mechanicky odstranila.232 039 layer of graphite by brushing and sweating with a brush applied Hycar 2600x138 (polyacrylonitrile rubber emulsion) · After applying several layers of Hyoar 2600x138 with a total thickness of 3.10 °, the samples were dried in an oven at 120 to 140 ° C · and mechanically removed it very easily.
U kontrolných vzoriek, ktoré neobsahovali medzivrstvu z grafitu, sa zosietený film vóbec nedal odstranit·Controls that did not contain an interlayer of graphite could not remove the crosslinked film at all ·
