V tomto aerosolu se nach\u00e1z\u00ed mimo jin\u00e9 l\u00e1tky: voda, enzymy, miner\u00e1ln\u00ed l\u00e1tky. Aerosol v n\u00e1stroji kondenzuje a zm\u00edn\u011bn\u00e9 l\u00e1tky reaguj\u00ed se st\u011bnou d\u0159ev\u011bn\u00e9ho n\u00e1stroje.

Povrch tak ch\u0159adne a postupem \u010dasu je do sebe schopn\u00fd rychleji absorbovat v\u00edce vlhkosti.

                    Pokud se n\u00e1stroj nach\u00e1z\u00ed po v\u011bt\u0161inu \u010dasu ve velmi such\u00e9m prost\u0159ed\u00ed m\u00e1 tendenci se stahovat.

Vezmeme-li v potaz, \u017ee se ve stejnou chv\u00edli na n\u00e1stroj hraje a toto d\u0159evo je schopno absorbovat v\u00edce vlhkosti, jin\u00fdmi slovy nab\u00fdvat na objemu. P\u016fsob\u00ed s\u00edla ze st\u0159edu n\u00e1stroje sm\u011brem ven. V tomto p\u0159\u00edpad\u011b doch\u00e1z\u00ed k p\u016fsoben\u00ed dvou sil proti sob\u011b a jeliko\u017e se nemohou tyto s\u00edly uvolnit do prostoru, m\u016f\u017ee doj\u00edt k prasknut\u00ed.<\/p>\n

Vezmeme-li tedy n\u00e1stroj do velmi chladn\u00e9ho prost\u0159ed\u00ed a za\u010dneme na n\u011bj hr\u00e1t, doch\u00e1z\u00ed k tomu, \u017ee vn\u011bj\u0161\u00ed vrstvy n\u00e1stroje maj\u00ed tendenci se stahovat a vnit\u0159n\u00edm p\u016fsoben\u00edm dod\u00e1van\u00e9ho tepl\u00e9ho a vlhk\u00e9ho vzduchu roztahovat.<\/p>\n

                    Vr\u00e1t\u00edme-li se tedy k t\u00e9matu olejov\u00e1n\u00ed, vych\u00e1z\u00ed n\u00e1m, \u017ee jistou formou prevence prasknut\u00ed je o\u0161et\u0159en\u00ed d\u0159ev\u011bn\u00e9ho t\u011bla z venku i zevnit\u0159.<\/strong><\/p>\n

Vzhledem k tomu, \u017ee ka\u017ed\u00e9 d\u0159evo po sklizni sesych\u00e1 a m\u011bn\u00ed sv\u016fj objem i d\u00e9lku, nav\u00edc sesych\u00e1 nerovnom\u011brn\u011b, je naprosto z\u00e1sadn\u00ed jeho mnoholet\u00e1 p\u0159\u00edprava.

    Jak olejovat ?<\/strong><\/p>\n

    Je nutno zm\u00ednit, \u017ee jak\u00e9koliv d\u0159evo s hustotou kolem 1200 kg\/m3<\/sup> nen\u00ed mo\u017en\u00e9 bez vyu\u017eit\u00ed tlaku a tepla alespo\u0148 trochu „proolejovat“.
