PolyDADMAC, ane zita rakazara rinonziPolydimethyldiallylammonium chloride, imusanganiswa wepolymer unoshandiswa zvakanyanya mumunda wekurapa mvura. Nekuda kwehunhu hwayo hwakasiyana, hwakadai sekupfakanyika zvakanaka uye kugadzikana, PolyDADMAC inoshandiswa zvakanyanya mumaindasitiri akadai sekurapa mvura, kugadzira mapepa, machira, migodhi, uye minda yemafuta.
Munzvimbo yemvura yekunwa, PolyDADMAC inoshandiswa seflocculant, iyo inogona kubvisa zvinobudirira zvinhu zvakasimba zvakamiswa, colloids, uye tsvina mumvura uye kuvandudza kunaka kwemvura. Musimboti wayo wekushanda ndewekuti kuburikidza nekuchinjana kwemaion uye charge neutralization, zvidimbu netsvina mumvura zvinogona kuunganidzwa pamwe chete kuti zvigadzire zvidimbu zvikuru zviri nyore kugadzirisa, nokudaro zvichichenesa kunaka kwemvura. PolyDADMAC inobvisa zvinobudirira turbidity, ruvara uye huwandu hwese hwe organic carbon mumvura uye inoderedzawo ruvara uye huwandu hwese hwe organic carbon, kuitira kuti mhando yemvura yekunwa ive nani.
PolyDADMAC ine basa rakakoshawo mumunda wemvura yakasviba yemumaindasitiri. Sezvo mvura yakasviba yemumaindasitiri ichiwanzova nehuwandu hwakawanda hwezvinhu zvakasimba zvakamiswa, maion esimbi inorema, zvinhu zvakasikwa nezvimwe zvinhu zvinokuvadza, kubudiswa zvakananga kunokonzera kusvibiswa kwakanyanya kunharaunda. Nekuwedzera huwandu hwakakodzera hwePolyDADMAC, zvinhu zvinokuvadza mumvura yakasviba zvinogona kusanganiswa kuita zvidimbu zvikuru, zviri nyore kugadzirisa nekuparadzanisa, nokudaro zvichiita kuti mvura yakasviba icheneswe. Kunze kweizvozvo, PolyDADMAC inewo mamwe mabasa ekubvisa ruvara, izvo zvinogona kuderedza ruvara rwemvura yakasviba uye kuita kuti zvive nyore kusangana nezvinodiwa pakubudiswa.
Uye mumunda wekuchera nekugadzira zvicherwa, PolyDADMAC inonyanya kushandiswa pakugadzika nekudzikamisa slurry. Nekuwedzera PolyDADMAC, kuyerera kweslurry kunogona kuvandudzwa, zvichibvumira zvidimbu zvakasimba muslurry kuti zvifambe zvakanaka uye zvigare zvakanaka, uye kuwedzera mwero wekudzoreredza zvicherwa. Pamusoro pezvo, PolyDADMAC inogonawo kushandiswa senzira yekudzora slurry.Mumiriri weFloatinguye zvinodzivisa, zvichibatsira kuwana kupatsanurwa kwakanaka uye kuwedzerwa kwemaminerari.
Indasitiri yemachira ndeimwe nzvimbo inoshandiswa zvakanyanya nePolyDADMAC. Mukuita kwemachira, mvura yakawanda nemakemikoro zvinoshandiswa, uye mvura yakasviba inogadzirwa ine tsvina yakaita semafiber, madhayi, uye zvimwe zvemakemikari. Nekuwedzera PolyDADMAC, tsvina yakaita sezvinhu zvakasungirirwa uye madhayi mumvura yakasviba inogona kubviswa zvinobudirira, uye ruvara nekusvibiswa kwemvura yakasviba kunogona kuderedzwa.
Panguva imwe chete, PolyDADMAC inogonawo kushandiswa semushonga wekupedzisa mavara uye unopfavisa machira, zvichibatsira kuvandudza mhando nekunyaradzwa kwemachira.
Maitiro ekugadzira mapepa ndeimwe nzvimbo inokosha yekushandiswa kwePolyDADMAC. Munguva yekugadzira mapepa, mvura yakawanda nemakemikari zvinoshandiswa, uye mvura yakasviba inogadzirwa ine tsvina dzakadai semafiber, fillers, uye dyes. Nekuwedzera PolyDADMAC, tsvina dzakadai sema suspended solids uye dyes mumvura yakasviba inogona kubviswa zvinobudirira, ruvara uye turbidity yemvura yakasviba inogona kuderedzwa, uye mhando nesimba repepa zvinogona kuvandudzwa panguva imwe chete. Zvakare, PolyDADMAC inogona kushandiswa se binder uye thickener ye paper coating, ichibatsira kuvandudza gloss uye isapinda mvura yepepa.
Indasitiri yemafuta inzvimbo yakakosha yekushandiswa kwePolyDADMAC. Munguva yekuchera mafuta, mvura yakawanda inoraswa nemafuta ichagadzirwa, uye kubudiswa zvakananga kuchakonzera kusvibiswa kwakanyanya kunharaunda. Nekuwedzera PolyDADMAC, madonhwe emafuta ari mutsvina anogona kuunganidzwa pamwe chete kuti aumbe zvidimbu zvikuru zviri nyore kupatsanura, nokudaro zvichiita kuti mafuta aparadzane nemvura. Pamusoro pezvo, PolyDADMAC inogonawo kushandiswa semushonga wekubvisa mvura uye mushonga wekutonga panguva yekugadzira mafuta, zvichibatsira kudzora mafashamo emvura uye kuvandudza kudzoreredzwa kwemafuta.
Zvose pamwe chete, PolyDADMAC, sechinhu chakakoshaMakemikari Ekurapa Mvurauye makemikari emaindasitiri, ane mashandisirwo akasiyana-siyana. Anoita basa rakakosha mumvura yekunwa, mvura yakasviba yemaindasitiri, migodhi, kugadzirwa kwezvicherwa, minda yemachira, mapepa, uye mafuta. Mune ramangwana, nekuvandudzwa kwezvinodiwa zvekuchengetedza zvakatipoteredza uye kushomeka kwezviwanikwa zvemvura kuri kuwedzera, mikana yekushandiswa kwePolyDADMAC ichave yakakura.
