1. Proces proizvodnje flokulantov - metoda hidrolize.
V primerjavi z metodo kopolimerizacije vodni topni faktor protiteze (HD) izdelka, pripravljeni s splošno metodo hidrolize, ni visok, manj kot 30%, teoretično pa je treba produkt HD, večjega od 70%, pripraviti s kopolimerizacijo, metoda pa ima določene zahteve za temperaturo hidrolize. Hkrati se med postopkom hidrolize verjetno pojavi makromolekularna razgradnja. Yan Laning in drugi z univerze Tianjin so preučevali metodo hidrolize s hidroliznim sredstvom NaOH in NA2CO3. Ugotovljeno je bilo, da NaOH ne samo pospeši hidrolizo, ampak tudi poglobi hidrolizo. Če je vredno uporabiti nizko hidrolizacijo (<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 proizvodnje flokulanta Tri: Polimerizacija inverzne emulzije
Pred inverzno emulzijsko polimerizacijo in suspenzijsko polimerizacijo z obratno fazo je treba pripraviti koloidni disperzijski sistem reverzne faze, to je, da se heterogeni disperzijski sistem vodne olje (w/0) tvori z mešanjem vodne raztopine monomera z mešanjem ali razprševanjem oljne faze. Za radikalno polimerizacijo se doda pobudnik.
