Ini ndinosarudza sei Polyacrylamide mhando?

Polyacrylamide(PAM) kazhinji inogona kuiswa muanionic, cationic, uye nonionic zvichienderana neiyo ion mhando. Inonyanya kushandiswa flocculation mukurapa mvura. Pakusarudza, marudzi akasiyana emvura yakasvibiswa anogona kusarudza marudzi akasiyana. Iwe unofanirwa kusarudza iyo PAM yakakodzera maererano nehunhu hwetsvina yako. Panguva imwecheteyo, iwe unofanirwawo kujekesa kuti ndeipi nzira iyo polyacrylamide ichawedzerwa uye chinangwa chaunoda kuzadzisa nekuishandisa.

The michina zviratidzo zvepolyacrylamide kazhinji zvinosanganisira molecular uremu, dhigirii hydrolysis, ionicity, viscosity, residual monomer content, etc. Aya zviratidzo zvinofanira kujekeswa maererano netsvina yauri kurapa.

1. Molecular uremu / viscosity

Polyacrylamide ine uremu hwakasiyana-siyana hwemamorekuru, kubva pasi kusvika pakakwirira. Huremu hwemamorekuru hunokanganisa mashandiro emapolymer mumashandisirwo akasiyana. Yakakwira molecular huremu polyacrylamide inowanzo shanda zvakanyanya mukuita flocculation nekuti cheni dzavo dzepolymer dzakareba uye dzinogona kubatanidza zvimwe zvimedu pamwechete.

Iyo viscosity yePAM mhinduro yakakwira zvakanyanya. Kana iyo ionization yakagadzikana, iyo yakakura iyo molecular huremu hwepolyacrylamide, iyo yakakura viscosity yemhinduro yayo. Izvi zvinodaro nekuti iyo macromolecular cheni yepolyacrylamide yakareba uye yakatetepa, uye kuramba kufamba mune mhinduro yakakura kwazvo.

2. Dhigirii re hydrolysis uye iocity

Iyo ionicity yePAM ine pesvedzero huru pakushandisa kwayo, asi kukosha kwayo kwakakodzera kunoenderana nerudzi uye chimiro chechinhu chakarapwa, uye kune akasiyana akanyanya kukosha mumamiriro akasiyana. Kana iyo ionic simba yezvinhu zvakarapwa yakakwirira (yakawanda inorganic matter), iyo ionicity yePAM inoshandiswa inofanira kunge yakakwirira, kana zvisina kudaro inofanira kunge yakaderera. Kazhinji, dhigirii reanion rinonzi dhigirii rehydrolysis, uye dhigirii reion rinowanzodaidzwa kuti dhigirii re cation.

Nzira yekusarudza polyacrylamidezvinoenderana nehuwandu hwemacolloid uye zvakaturikwa zvimedu mumvura. Mushure mekunzwisisa zviratidzo zviri pamusoro, ungasarudza sei PAM yakakodzera?

1. Nzwisisa panobva suweji

Kutanga, isu tinofanira kunzwisisa kwainobva, hunhu, kuumbwa, yakasimba zvemukati, nezvimwe zve sludge.

Kazhinji kutaura, cationic polyacrylamide inoshandiswa kurapa organic sludge, uye anionic polyacrylamide inoshandiswa kurapa inorganic sludge. Kana pH yakakwira, cationic polyacrylamide haifanirwe kushandiswa, uye kana , anionic polyacrylamide haifanirwe kushandiswa. Asidhi yakasimba inoita kuti isakodzere kushandisa anionic polyacrylamide. Kana iyo yakasimba yedhaka yakakwira, huwandu hwepolyacrylamide hunoshandiswa hwakakura.

2. Kusarudzwa kweiyonicity

For sludge inoda kuderedzwa mvura mukurapwa kwetsvina, unogona kusarudza flocculants ine akasiyana ionicity kuburikidza diki kuyedza kusarudza iyo inonyanya kukodzera polyacrylamide, iyo inogona kuwana yakanakisa flocculation mhedzisiro uye kuderedza dosi, kuchengetedza mari.

3. Kusarudzwa kwema molecular weight

Kazhinji kutaura, kukwira kwema molecular huremu hwezvigadzirwa zvepolyacrylamide, kunowedzera viscosity, asi mukushandiswa, kukwirisa huremu hwechigadzirwa, kunowedzera kunaka kwekushandisa. Mukushandiswa chaiko, iyo yakakodzera mamorekuru uremu hwepolyacrylamide inofanirwa kuve yakatemwa maererano neiyo chaiyo yekushandisa indasitiri, mhando yemvura uye mishonga yekurapa.

Paunotenga nekushandisa PAM kekutanga, zvinokurudzirwa kuti upe iyo chaiyo mamiriro etsvina kune iyo flocculant mugadziri, uye isu tichakurudzira yakanyatsokodzera chigadzirwa mhando kwauri. Uye mail samples yekuyedza. Kana uine ruzivo rwakawanda mukurapwa kwako kwetsvina, unogona kutiudza zvaunoda chaizvo, nzvimbo dzekushandisa, uye maitirwo, kana zvakananga kutipa PAM samples dzauri kushandisa parizvino, uye isu tichakufananidza neiyo polyacrylamide chaiyo.
