Nigute nahitamo ubwoko bwa Polyacrylamide?

Polyacrylamide(PAM) mubisanzwe birashobora gushyirwa mubice bya anionic, cationic, na nonionic ukurikije ubwoko bwa ion. Ikoreshwa cyane cyane mugutunganya amazi. Mugihe uhisemo, ubwoko butandukanye bwamazi ashobora guhitamo ubwoko butandukanye. Ugomba guhitamo PAM iburyo ukurikije ibiranga imyanda yawe. Muri icyo gihe, ugomba kandi gusobanura inzira polyacrylamide izongerwamo nintego ushaka kugeraho ukoresheje.

Ibipimo bya tekinike ya polyacrylamide muri rusange birimo uburemere bwa molekile, urugero rwa hydrolysis, ionicity, viscosity, monomer isigaye, nibindi. Ibi bipimo bigomba gusobanurwa ukurikije amazi mabi urimo uvura.

1. Uburemere bwa molecular / viscosity

Polyacrylamide ifite uburemere butandukanye bwa molekile, kuva hasi kugeza hejuru cyane. Uburemere bwa molekulari bugira ingaruka kumikorere ya polymers mubikorwa bitandukanye. Uburemere buke bwa polyacrylamide mubusanzwe bukora neza mugikorwa cya flocculation kuko iminyururu ya polymer ari ndende kandi irashobora guhuza ibice byinshi hamwe.

Ubukonje bwibisubizo bya PAM ni hejuru cyane. Iyo ionisiyoneri itajegajega, nini uburemere bwa molekile ya polyacrylamide, niko ubwinshi bwibisubizo byabwo. Ni ukubera ko urunigi rwa macromolecular ya polyacrylamide ari rurerure kandi ruto, kandi kurwanya guhangana nigisubizo ni binini cyane.

2. Impamyabumenyi ya hydrolysis na ionicity

Iionicity ya PAM igira uruhare runini mubikorwa byayo, ariko agaciro kayo gashingiye kumiterere na miterere yibikoresho bivurwa, kandi hariho indangagaciro nziza zitandukanye mubihe bitandukanye. Iyo ionic imbaraga zibikoresho bivuwe ari byinshi (ibintu byinshi bidakoreshwa), ionicity ya PAM yakoreshejwe igomba kuba hejuru, naho ubundi igomba kuba hasi. Mubisanzwe, urwego rwa anion rwitwa urwego rwa hydrolysis, naho urwego rwa ion rwitwa urwego rwa cation.

Nigute ushobora guhitamo polyacrylamidebiterwa nubunini bwa colloide hamwe nibintu byahagaritswe mumazi. Nyuma yo gusobanukirwa ibipimo byavuzwe haruguru, nigute ushobora guhitamo PAM ibereye?

1. Sobanukirwa n'inkomoko y'imyanda

Ubwa mbere, tugomba gusobanukirwa inkomoko, kamere, ibihimbano, ibintu bikomeye, nibindi bya silige.

Muri rusange, polyacrylamide cationic ikoreshwa mugutunganya imyanda kama, na anionic polyacrylamide ikoreshwa mukuvura imyanda idasanzwe. Iyo pH ari ndende, polyacrylamide cationic ntigomba gukoreshwa, kandi mugihe, anionic polyacrylamide ntigomba gukoreshwa. Acide ikomeye ituma bidakwiriye gukoresha anionic polyacrylamide. Iyo ibintu bikomeye bya silige ari byinshi, ubwinshi bwa polyacrylamide yakoreshejwe ni bunini.

2. Guhitamo ionicity

Kumashanyarazi akeneye kubura umwuma mugutunganya imyanda, urashobora guhitamo flocculants hamwe na ionicity zitandukanye binyuze mubushakashatsi buto kugirango uhitemo polyacrylamide ikwiye, ishobora kugera kumikorere myiza ya flokculasiyo no kugabanya dosiye, kuzigama amafaranga.

3. Guhitamo uburemere bwa molekile

Muri rusange, uko uburemere bwa molekuline bwibicuruzwa bya polyacrylamide, niko bigenda byiyongera, ariko mugukoresha, uburemere bwa molekile bwibicuruzwa, niko ingaruka nziza yo gukoresha. Mugukoresha byihariye, uburemere bukwiye bwa polyacrylamide bugomba kugenwa ukurikije inganda zikoreshwa, ubwiza bwamazi nibikoresho byo gutunganya.

Mugihe uguze kandi ugakoresha PAM kunshuro yambere, birasabwa gutanga imiterere yihariye yimyanda kumasoko ya flocculant, kandi tuzagusaba ubwoko bwibicuruzwa bikwiye kuri wewe. Nohereze icyitegererezo cyo kwipimisha. Niba ufite uburambe bwinshi muburyo bwo gutunganya imyanda, urashobora kutubwira ibisabwa byihariye, imirima yo gusaba, hamwe nibikorwa, cyangwa ukaduha mu buryo butaziguye urugero rwa PAM ukoresha ubu, kandi tuzaguhuza na polyacrylamide ibereye.
