1. Proces proizvodnje flokulanata - metoda hidrolize.
U usporedbi s metodom kopolimerizacije, u vodi topivim antisundruff faktorom (HD) proizvoda pripremljenog općom metodom hidrolize nije visok, manji od 30%, a teoretski, proizvod HD veći od 70% trebao bi se pripremiti metodom kopolimerizacije, a metoda ima određene potrebe za hidrolizom i događajima. Istodobno, makromolekularna razgradnja vjerojatno će se pojaviti tijekom postupka hidrolize. Yan Laneing i drugi sa Sveučilišta Tianjin proučavali su metodu hidrolize s agensom hidrolize NaOH i Na2CO3. Utvrđeno je da NaOH ne samo da ubrzava hidrolizu, već i produbljuje hidrolizu. Ako je vrijedno koristiti nisku hidrolizmu (<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 flokulanata tri: obrnuta emulzijska polimerizacija
Prije polimerizacije ovjesa za inverznu emulziju i polimerizacije suspenzije obrnute faze, potrebno je pripremiti sustav koloidne disperzije obrnute faze, to jest, vodeno-ulje (w/0) heterogeni sustav disperzije nastaje miješanjem vodenog otopine monomera. Inicijator se dodaje za radikalnu polimerizaciju.
