1. Flokulantu ražošanas process - hidrolīzes metode.
Salīdzinot ar kopolimerizācijas metodi, ar ūdeni šķīstošais antibulbonu koeficients (HD), kas sagatavots ar vispārējo hidrolīzes metodi, nav augsts, mazāks par 30%, un teorētiski HD produkts, kas lielāks par 70%, jāsagatavo ar kopolimerizācijas metodi, un metodei ir noteiktas prasības hidrolīzes temperatūrai un notikumiem. Tajā pašā laikā hidrolīzes procesā, visticamāk, notiks makromolekulārā sadalīšanās. Yan Lanying un citi no Tjandzjinas universitātes pētīja hidrolīzes metodi ar hidrolīzes līdzekli NaOH un NA2CO3. Tika konstatēts, ka NaOH ne tikai paātrina hidrolīzi, bet arī padziļina hidrolīzi. Ja ir vērts izmantot zemu hidrolizitāti (<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. Flokulantu ražošanas process Trešais: apgrieztā emulsijas polimerizācija
Pirms apgrieztas emulsijas polimerizācijas un apgrieztās fāzes suspensijas polimerizācijas ir jāsagatavo reversās fāzes koloidālās izkliedes sistēma, tas ir, ūdens eļļas (ar w/0) neviendabīgu izkliedes sistēmu veido momenta, maisot vai izkliedējot eļļas fāzi. Iniciatoru pievieno radikālai polimerizācijai.
