1. Proces výroby flokulantov - Metóda hydrolýzy.
V porovnaní s metódou kopolymerizácie nie je vo vode rozpustný anti-lupový faktor (HD) produktu pripravený všeobecnou hydrolýznou metódou vysoký, menej ako 30% a teoreticky by sa produkt HD väčší ako 70% mal pripraviť metódou kopolymerizácie a metóda má určité požiadavky na teplotu hydrolýzy a udalosti. Súčasne sa počas procesu hydrolýzy pravdepodobne vyskytne makromolekulárna degradácia. Yan Lanying a ďalšie z univerzity Tianjin študovali metódu hydrolýzy s hydrolýzovým činidlom NaOH a Na2Co3. Zistilo sa, že NaOH nielen zrýchľuje hydrolýzu, ale tiež prehlbuje hydrolýzu. Ak sa oplatí používať nízku hydrolyznosť (<10%) latex, NaOH can be used as a hydrolyzing agent. To make a latex with a degree of hydrolysis (greater than 10%), it is best to co-hydrolyze with NaOH and Na2CO3 to achieve a shorter time. High hydrolysis value. In recent years, high molecular weight, especially ultra-high molecular weight acrylic acid, acrylamide polymers have had an undisputed role in tertiary oil recovery. Compared with the hydrolysis method, the AA/AM copolymer prepared by the copolymerization method generally has a relatively low molecular weight and poor water solubility, and thus the ultrahigh molecular weight AA/AM copolymer is prepared by a hydrolysis method. Ji Hongyan, Sun Zhanwei and others established a latent initiation system for aqueous solution polymerization of acrylamide. The carbonate polymerization method was added to add different amounts of ammonia, urea, EDTA-2Na, and the pH value and monomer concentration of the polymerization system. The influence of the temperature of the polymerization water bath on the relative molecular mass and solubility of the polymerized product and its cause solve the contradiction between the high molecular weight of the product and the insoluble polymer. Li Xiaofu and Li Miangui synthesized anionic polyacrylamide with molecular weight greater than 1×10 by the combination of heterogeneous hydrolysis and reverse suspension. The relationship between hydrolysis degree and hydrolysis time and system pH value, and different water-alcohol ratio were studied. Under the condition of the relationship between the degree of hydrolysis and time, the degree of hydrolysis and temperature, the reaction conditions of ultra-high molecular weight fast-dissolving polyacrylamide were obtained.

3. Proces výroby flokulantov tri: inverzná emulzná polymerizácia
Pred inverznou emulznou polymerizáciou a polymerizáciou suspenzie zvratnej fázy je potrebné pripraviť sa reverzný disperzný systém koloidného fázy, tj vodný roztok monoméru (w/{{}}) sa vytvára miešaním vodného roztoku monoméru miešaním alebo dispergovaním olejovej fázy. Iniciátor sa pridá pre radikálnu polymerizáciu.
