Description
Koloidy, jak naprzyklad zelatyna, roz¬ maite rodzaje bialka i L d., wywieraja, jak wiadomo, dzialanie ochronne na cza¬ steczki zawieszone w wodzie, otaczajac te czasteczki i chroniac je od scinania sie w platki oraz osiadania.Pokazalo sie jednak, ze pewne kolo¬ idy, dodane w drobnych ilosciach do pew¬ nych zawiesin, wywieraja dzialanie wrecz przeciwne, laczac czasteczki zawieszone w platki i wywolujac czestokroc przyspie¬ szone ich osiadanie.Szczególnie korzystnie dzialaja w tym kierunku wyciagi (ekstrakty) roslinne, jak np, z mchu (karagenowego), pewne soki owocowe lub z jarzyn i t, d., nastepnie skrobia i przerózne kleje, jak równiez nie¬ które roztwory bialkowe, np, z mleka, krwi i t. d. Szczególnie energicznie dzia¬ laja wyciagi te w nieznacznej domieszce, przyspieszajac osiadanie mulów i zgre- zów przy plókaniu rud i wegla.Przyklad: w rurze szklanej dlugosci 1 m pozostawiono 1 1 od 5 do 10% szlamu weglowego bez domieszek, Po uplywie 1 do 2 godzin zgrezy te osadzily sie bardzo zle. Po dodaniu jednak 2 mg mchu kara¬ genowego w rozczynie wodnym nastepo¬ walo doskonale oczyszczenie plynu z me¬ tów juz po 1 lub 2 min, W tej samej rurze umieszczono 1 1 mu¬ lu rudy zelaznej. Bez dodatków niedo¬ kladne oczyszczenie plynu wymagalo oko¬ lo 50 min. Dodatek natomiast 2 mg klejuskórnego, lub 2 mg rozpuszczonego kroch¬ malu sprawial, ze plyn byl zupelnie czysty w ciagu 2 lub 3 min. W podobny sposób dzialaja pewne roztwory bialka. PL PLColloids, such as gelatin, various types of protein and L d, are known to have a protective effect on the particles suspended in the water, surrounding them and preventing them from tearing into flakes and settling. certain colloids, added in small amounts to certain suspensions, exert the opposite effect by binding the suspended particles into flakes and causing them to settle frequently faster. Plant extracts such as, for example, moss (carrageenan), certain fruit or vegetable juices, etc., then starch and various adhesives, as well as some protein solutions, for example, from milk, blood, etc. These extracts, in slight admixture, are particularly vigorous, accelerating sedimentation of silt and coarse grains at the flaking of ores and coal. Example: 1 1 of 5 to 10% carbon sludge was left in a 1 m long glass pipe without admixture. After 1 to 2 hours, these spindles deposited very badly. However, after adding 2 mg of carrageenan moss in an aqueous solution, the liquid was perfectly cleared of metals after 1 or 2 minutes. In the same pipe, 1 liter of iron ore was placed in the same pipe. Without additives, the inaccurate cleaning of the fluid required about 50 minutes. On the other hand, the addition of 2 mg of skin glue, or 2 mg of dissolved starch, made the liquid completely clean within 2 or 3 minutes. Certain protein solutions work in a similar way. PL PL
