Ndingasarudza sei mhando yePolyacrylamide?

Polyacrylamide(PAM) inogona kupatsanurwa muzvikamu zveanionic, cationic, uye nonionic zvichienderana nerudzi rweion. Inonyanya kushandiswa pakuyerera kwemvura mukuchenesa mvura. Pakusarudza, mhando dzakasiyana dzemvura yakasviba dzinogona kusarudza mhando dzakasiyana. Unofanira kusarudza PAM chaiyo zvichienderana nehunhu hwetsvina yako. Panguva imwe chete, unofanirawo kutsanangura kuti polyacrylamide ichawedzerwa sei uye chinangwa chaunoda kuzadzisa nekuishandisa.

Zviratidzo zvehunyanzvi zvepolyacrylamide zvinowanzo sanganisira huremu hwemamorekuru, mwero wehydrolysis, ionicity, viscosity, residual monomer content, nezvimwewo. Zviratidzo izvi zvinofanirwa kujekeswa zvichienderana nemvura yakasviba yauri kurapa.

1. Kurema kwemamorekuru/kusimba

Polyacrylamide ine huremu hwakasiyana-siyana hwemamorekuru, kubva pahudiki kusvika pahurefu. Huremu hwemamorekuru hunokanganisa mashandiro emapolymers mukushandiswa kwakasiyana. Polyacrylamide ine huremu hwakawanda hwemamorekuru inowanzo shanda zvakanyanya mukuita kweflocculation nekuti macheni avo epolymer akareba uye anogona kubatanidza zvidimbu zvakawanda pamwe chete.

Kuwanda kwemvura inonyungudika yePAM kwakakwira zvikuru. Kana ionization yagadzikana, huremu hwemamorekuru epolyacrylamide hwakakura, kuwanda kwemvura inonyungudika yemvura inonyungudika. Izvi zvinodaro nekuti cheni yemamorekuru epolyacrylamide yakareba uye yakatetepa, uye kuramba kufamba kwemvura mumushonga kwakakura kwazvo.

2. Dhigirii rehydrolysis uye ionicity

Ionicity yePAM ine simba guru pakushandiswa kwayo, asi kukosha kwayo kwakakodzera kunoenderana nerudzi uye hunhu hwechinhu chakarapwa, uye kune akasiyana maongororwo akanaka mumamiriro akasiyana. Kana simba reionic rechinhu chakarapwa rakakwirira (zvakawanda zvisingasanganisike), ionicity yePAM inoshandiswa inofanira kunge yakakwira, zvikasadaro inofanira kunge yakaderera. Kazhinji, degree yeanion inonzi degree of hydrolysis, uye degree yeion inowanzonzi degree of cation.

Nzira yekusarudza polyacrylamidezvinoenderana nehuwandu hwema colloids nezvinhu zvakasimba zvakasungirirwa mumvura. Mushure mekunzwisisa zviratidzo zviri pamusoro apa, ungasarudza sei PAM yakakodzera?

1. Nzwisisa kunobva tsvina

Kutanga, tinofanira kunzwisisa kwakabva, hunhu, maumbirwo, zviri mukati mayo, nezvimwewo.

Kazhinji, cationic polyacrylamide inoshandiswa kurapa tsvina yeorganic, uye anionic polyacrylamide inoshandiswa kurapa tsvina yeinorganic. Kana pH yakakwira, cationic polyacrylamide haifanirwe kushandiswa, uye kana , anionic polyacrylamide haifanirwe kushandiswa. Acidity yakasimba inoita kuti isakodzere kushandisa anionic polyacrylamide. Kana tsvina yacho yakanyanya, huwandu hwepolyacrylamide inoshandiswa hwakakura.

2. Kusarudzwa kweionicity

Kune tsvina inoda kuomeswa nemvura mukuchenesa tsvina, unogona kusarudza zvinhu zvinosanganisa mvura zvine ionicity yakasiyana kuburikidza nekuyedza kudiki kuti usarudze polyacrylamide yakakodzera, iyo inogona kuwana mhedzisiro yakanaka ye flocculation uye kuderedza chiyero, zvichichengetedza mari.

3. Kusarudzwa kwehuremu hwemamorekuru

Kazhinji, kana huremu hwemamorekuru hwezvigadzirwa zvepolyacrylamide hwakakwira, viscosity inowedzera, asi kana ichishandiswa, huremu hwemamorekuru hwechigadzirwa hwakawedzera, mhedzisiro yekushandiswa kwayo inowedzera. Pakushandiswa kwakananga, huremu hwemamorekuru hwakakodzera hwepolyacrylamide hunofanirwa kutsanangurwa zvichienderana neindasitiri chaiyo yekushandisa, mhando yemvura uye michina yekurapa.

Kana uchitenga uye uchishandisa PAM kekutanga, zvinokurudzirwa kuti upe mamiriro chaiwo etsvina kumugadziri weflocculant, uye isu tichakurudzira rudzi rwechigadzirwa chakakodzera iwe. Uye tumira sampuro kuti dziongororwe. Kana uine ruzivo rwakawanda mukuchenesa tsvina yako, unogona kutiudza zvaunoda, nzvimbo dzekushandisa, uye maitiro, kana kutipa zvakananga sampuro dzePAM dzauri kushandisa parizvino, uye tichakuenzanisa nepolyacrylamide yakakodzera.
