Description

Vynález ea týká regulátora rýohlosti rozpúšťania hnojivá vo vodnom prostředí podlá potrieb, danýoh příslušnými agrotechnickými a klimatickými podmienkami.The present invention relates to a regulator of dissolution rate of a fertilizer in an aqueous environment as required by the respective agrotechnical and climatic conditions.

Priemyselné hnojivá, ak nie eú upravené, sú vo vodnom prostředí relativné dobré rozpustné, preto po ich aplikáoii, vplyvom nárazových vodnýoh zrážok, roztoky týchto hnojív rýchlo prenikajú do takých híbok p6dy, kde namiesto pozitívneho biologického pSsobenia znečisťuji! spodná vody, takže efektivnost využitia živin v priemyselných hnojiváoh pri ioh pSvodnej aplikačnej formě je relativné nízká. Podlá súčaaného stavu techniky je problém regulácie ich rozpustnosti riešený například zvléštnym apSsobom poetreku granulovanou sírou /pat. USA č. 3 295 950/, čo si však vyžaduje zložitú technolo'giu aplikáoie. Použitie stearamu vápenatého v množstve 1 kg na tonu hnojivá /špan. pat. č.Industrial fertilizers, if not treated, are relatively well soluble in the aquatic environment, therefore, after their application, due to the impact of rainfall, the solutions of these fertilizers rapidly penetrate into soil depths where, instead of the positive biological effect, I contaminate them! ground water, so that the nutrient utilization efficiency of industrial fertilizers in the aqueous application form is relatively low. According to the state of the art, the problem of controlling their solubility is solved, for example, by a special method of granulated sulfur / pat spray. US # No. 3,295,950], which however requires complex technology applications. Use of 1 kg of calcium stearam per ton of fertilizer / span. pat. no.

418 582/, ako aj použitie močovino-formaldehydovýoh živíc, je zamerané hlavně na zníženie rozpustnosti hnojivá, zatial čo problém zníženia spiekavosti sa rieši inými chemickými látkami.No. 418,582), as well as the use of urea-formaldehyde resins, is mainly aimed at reducing the solubility of the fertilizer, while the problem of reducing sintering is addressed by other chemicals.

Uvedené nevýhody odstraňuje regulátor rýohlosti rozpúšťania hnojivá podlá vynálezu, ktorého podstata spočívá v použití derivátov siloxanov v pevnom, kvapalnom, alebo plynnom stave ako prostriedkov pre reguláoiu rýohlosti rozpúšťania hnojivá vo vodnom proetredí a zároveň pra zníženie jeho spiekavosti.These disadvantages are overcome by the fertilizer dissolution regulator according to the invention, which is based on the use of siloxane derivatives in solid, liquid or gaseous state as a means for controlling the fertilizer dissolution rate in an aqueous environment and at the same time reducing its sinterability.

Výhodou vynálezu je, že v dósledku bariérového účinku derivátov silánov, ako obalovadla častíc hnojívá, zníži sa rozpustnost tohto hnojivá vo voda, ktorú možno regulovat hmotnostným poměrom obalovadla voči priemyselnému hnojivu, ktorým je daná hrúbka vrstvy obalovadla, fialšou výhodou vynálezu je, že takto vytvořený povlak znižuje aj spiekavosť priemyselného hnojivá před jeho aplikáoiou.The advantage of the invention is that due to the barrier effect of the silane derivatives as fertilizer of the particles, the water solubility of the fertilizer, which can be controlled by the weight ratio of the fertilizer to the fertilizer given the coating layer thickness, is reduced. the coating also reduces the sinterability of the industrial fertilizer prior to application.

Silánový povlak na částice priemyselného hnojivá možno nanášať v plynnej, kvapalnej alebo tuhej fáze tohto obalovadla.The silane coating of the fertilizer particles can be applied in the gaseous, liquid or solid phase of the coating.

Příklady prevedenia:Examples:

Příklad 1Example 1

Metylhydrogénpolysiloxan sa v plynnom stave v záverečnej operácii výroby priemyselného hnojivá aplikuje v množstve 50 - 1500 g na 1 tonu priemyaelného hnojivá, ktorého velkost častío je v rozmedzí 0,01 - 5 mm. Okrem toho, že je matylhydrogénpolyailoxan látka chemicky stála, biologicky neškodná a odolná voči teplotám do 200 °C, polymerizuje na regulovatelný homogenny film, pričom svojou hydrofóbnosťou vytvára bariérový účinok. Bariérový účinok sa prejaví tak, že hrúbka povlaku 5 >um predíži čas do začiatku účinkovania hnojivá o oca 14 dní.Methylhydrogen polysiloxane is applied in the gaseous state in the final operation of industrial fertilizer production in an amount of 50 - 1500 g per tonne of industrial fertilizer, the size of which is often in the range of 0.01 - 5 mm. In addition to being chemically stable, biologically harmless and resistant to temperatures up to 200 ° C, the matylhydroxy polyailoxane polymerizes to a controllable homogeneous film, creating a barrier effect by its hydrophobicity. The barrier effect is manifested in that the coating thickness of 5 µm will prolong the time until the fertilizer starts to act by 14 days.

Příklad 2 kg metylhydrogénpolysiloxanu v kvapalnaj fáze, s prídavkom 5 hmotnostných % dibutylcindilaurátu ako tužidla, sa spolu rozpustia v trichlóretyléne na jednopeřcentný hmotnostný roztok, ktorým sa prsplachuje 1 tona hnojivá, ako NPK, liadok a pod., o velkosti častíc 0,01-5 mm.EXAMPLE 2 kg of methylhydroxy polysiloxane in the liquid phase, with the addition of 5% by weight of dibutylcindilaurate as a hardener, are dissolved together in trichlorethylene to a 1% by weight solution, rinsing 1 ton of fertilizer such as NPK, nuts and the like. mm.

Příklad 3 kg metylhydrogénpolysiloxanu v pevnej fáze sa aplikuje na 1 tonu hnojivá o velkosti častío 0,01 - 5 mm mechanickou homogenizáciou.EXAMPLE 3 kg of methylpolysiloxane in solid phase is applied per 1 ton of fertilizer with a particle size of 0.01-5 mm in size by mechanical homogenization.

Podobné vlastnosti ako metylhydrogénpolysiloxan majú aj ďalšie deriváty siloxanov, ako například polydimetylsiloxan, polymetylfenylsiloxan, alkylhydrogénpolyBiloxan a ďalšie.Other siloxane derivatives such as polydimethylsiloxane, polymethylphenylsiloxane, alkylhydroxy polybiloxane and others have similar properties to methylhydroxy polysiloxane.
