Musiyano uye kushandiswa kwePAM yecationic, anionic uye nonionic？

Polyacrylamide(PAM) ipolymer inoshandiswa zvakanyanya mukuchenesa mvura, kugadzira mapepa, kubvisa mafuta nedzimwe nzvimbo. Zvichienderana nehunyanzvi hwayo hweionic, PAM yakakamurwa kuita mhando nhatu huru: cationic (Cationic PAM, CPAM), anionic (Anionic PAM, APAM) uye nonionic (Nonionic PAM, NPAM). Mhando nhatu idzi dzine musiyano mukuru muchimiro, mashandiro uye mashandisirwo.

1. Cationic polyacrylamide (Cationic PAM, CPAM)

Maumbirwo uye hunhu:

Cationic PAM: Ipombi yepolymer yakatsetseka. Nekuti ine mapoka akasiyana-siyana anoshanda, inogona kuumba hydrogen bonds nezvinhu zvakawanda uye inonyanya kukonzera flocculate negative charge colloids. Yakakodzera kushandiswa mumamiriro eacidic.

Kushandiswa:

- Kurapa mvura yakasviba: CPAM inowanzoshandiswa kurapa mvura yakasviba isina chaji yakanaka, yakadai setsvina yemumaguta, mvura yakasviba inogadzirwa chikafu, nezvimwewo. Chaji dzakanaka dzinogona kusangana nezvidimbu zvakanyungudutswa zvine chaji yakaipa kuti zvigadzire maflocs, nokudaro zvichikurudzira kupatsanurwa kwemvura yakasimba.

- Indasitiri yemapepa: Mukugadzira mapepa, CPAM inogona kushandiswa semushonga wekusimbisa uye wekuchengetedza kuti ivandudze simba uye mwero wekuchengetedza mapepa.

- Kubviswa kwemafuta: Muminda yemafuta, CPAM inoshandiswa kurapa matope ekuchera kuti ideredze kusefa uye kukora.

2. Anionic polyacrylamide (Anionic PAM, APAM)

Maumbirwo uye hunhu:

Anionic PAM ipolymer inonyungudika mumvura. Nekuisa mapoka aya eanionic pamusana wepolymer, APAM inogona kuita zvinhu zvine chaji yakanaka. Inonyanya kushandiswa pakupwanyika, kupwanyika uye kucheneswa kwemvura dzakasiyana-siyana dzemaindasitiri. Yakakodzera kushandiswa mumamiriro ealkaline.

Kushandiswa:

- Kurapa mvura: APAM inoshandiswa zvakanyanya mumvura yekunwa uye mukurapa mvura yakasviba mumaindasitiri. Inogona kuumba zvidimbu zvakasungirirwa kuburikidza nemagetsi kana kuti kunyungudutsa, nokudaro ichivandudza kuchena kwemvura.

- Indasitiri yemapepa: Sekubatsira kuchengetedza nekusefa, APAM inogona kuvandudza mashandiro ekusefa kwemvura kwemupumburu uye kusimba kwepepa.

- Kuchera neKuisa Ore Dressing: Munguva yekuyangarara uye kudonha kwematombo, APAM inogona kukurudzira kudonha kwematombo uye kuvandudza mwero wekudzoreredza matombo.

- Kuvandudza Ivhu: APAM inogona kuvandudza chimiro chevhu, kuderedza kukurwa kwevhu, uye inoshandiswa zvakanyanya mukurima nekurima.

3. Nonionic Polyacrylamide (Nonionic PAM, NPAM)

Maumbirwo uye Zvimiro:

Nonionic PAM ipolymer yakakura kana kuti polyelectrolyte ine huwandu hwakati hwemajini epolar mucheni yayo yemamorekuru. Inogona kunyudza zvidimbu zvakasimba zvakasungirirwa mumvura uye kusanganisa zvidimbu kuti zvigadzire mafloccules makuru, kukurumidzisa kunyungudika kwezvidimbu zviri mukumiswa, kukurumidzisa kujeka kwemushonga, uye kukurudzira kusefa. Haina mapoka ane chaji uye inonyanya kuumbwa nemapoka emaamide. Chimiro ichi chinoita kuti iratidze kunyungudika kwakanaka uye kugadzikana mumamiriro ezvinhu asina kusimba uye asina acid. Nonionic PAM ine hunhu hwehukuru hwemamorekuru uye haikanganisike zvakanyanya ne pH value.

Kushandiswa:

- Kurapa Mvura: NPAM inogona kushandiswa kurapa mvura isina kusviba zvakanyanya, yakachena zvakanyanya, senge mvura yemumba nemvura yekunwa. Chakanakira ndechekuti inogona kuchinjika zvakanyanya kumamiriro emvura uye pH.

- Indasitiri yemicheka nedhayi: Mukugadzirisa machira, NPAM inoshandiswa sechinhu chinosimbisa uye chinosimbisa kunatsiridza kunamira kwedhayi uye kufanana kwedhayi.

- Indasitiri yesimbi: NPAM inoshandiswa semafuta anonhuhwirira uye anotonhodza mukugadzirisa simbi kuderedza kukweshana uye kuvandudza mashandiro ekugadzirisa.

- Kurima nekurima: Semushonga wekuchengetedza ivhu, NPAM inogona kuvandudza kugona kwevhu kuchengetedza mvura uye kukurudzira kukura kwezvirimwa.

Polyacrylamide yecationic, anionic uye nonionic ine minda yakasiyana yekushandisa uye mhedzisiro nekuda kwechimiro chayo chemakemikari chakasiyana uye hunhu hwayo hwekuchaja. Kunzwisisa uye kusarudza yakakodzeraPAMmhando iyi inogona kuvandudza zvakanyanya mashandiro ekugadzirisa uye mhedzisiro kuti ienderane nezvinodiwa nemaindasitiri akasiyana.
