Nekuda kwezvinodiwa zvakanyanya zvekuchengetedza nharaunda uye kuoma kuri kuramba kuchiwedzera kwekurapa mvura yakasviba mumaindasitiri, polydimethyldiallylammonium chloride (PDADMAC, fomura yemakemikari: [(C₈H₁₆NCl)ₙ])(https://www.cleanwat.com/poly-dadmac/)yava chinhu chakakosha. Hunhu hwayo hwekuyerera kwemvura, kushandiswa kwayo, uye hushamwari hwayo nezvakatipoteredza zvakaita kuti ishandiswe zvakanyanya mukuchenesa mvura uye mukurapa mvura yakasviba.
Nhanganyaya yeChigadzirwa
Iyo polymer ine mapoka akasimba ecationic uye mapoka anoshanda anowedzera kunhuhwirira. Kuburikidza nekudzikisa simba remagetsi uye kudzikamisa mvura, inokonzeresa kusagadzikana uye kupwanya zvidimbu zvakamiswa uye zvinhu zvinonyunguduka mumvura zvine mapoka ane chaji isina kunaka mumvura, zvichiratidza kushanda kwakakosha mukubvisa ruvara, kubvisa tsvina, uye kubvisa zvinhu zvipenyu. Chigadzirwa ichi chinoda dosi shoma, chinoburitsa maflocs makuru, chinogadzikana nekukurumidza, uye chinoita kuti pave nedutu shoma, zvichikonzera matope mashoma. Inoshandawo mukati me pH yakakura ye4-10. Hainhuhwi, haina kunaka, uye haina chepfu, zvichiita kuti ikodzere kushandiswa kwakasiyana-siyana kwekuchenesa mvura uye kushandiswa kwemvura yakasviba.
Maitiro Emhando Yepamusoro
| Muenzaniso | CW-41 |
| Chitarisiko | Mvura ine ruvara rwakareruka kusvika rweyero yakachenuruka, inoonekera, uye ine ganda rakapinza. |
| Zviri mukati mezvinhu zvakasimba (%) | ≥40 |
| Kusviba (mPa.s, 25°C) | 1000-400,000 |
| pH (1% mhinduro yemvura) | 3.0-8.0 |
| Cherechedza: Zvigadzirwa zvine simba rakasiyana uye zvinopenya zvinogona kugadziriswa kana zvakumbirwa. | |
Kushandiswa
Kana ikashandiswa yoga, mushonga unonyungudutsa mvura unofanira kugadzirwa. Huremu hwakajairika hunobva pa0.5% kusvika pa5% (kana tichitarisa huwandu hwezvinhu zvakaoma).
Pakurapa mvura yakasiyana-siyana nemvura yakasviba, chiyero chinofanira kusarudzwa zvichibva pakusvibiswa uye huwandu hwemvura yakarapwa. Chiyero chekupedzisira chinogona kutsanangurwa kuburikidza nemiedzo yekutanga.
Nzvimbo yekuwedzera uye kumhanya kwekukurunga zvinofanira kusarudzwa nokungwarira kuti zvive nechokwadi chekuti zvinosanganiswa zvakafanana nezvinhu izvi ukuwo zvichidzivirira kuti floc isaputsika.
Kuwedzera nguva dzose kunosarudzwa.
Mashandisirwo
Pakuyerera kwemvura, inogona kuvandudza kushanda zvakanaka kwekugadzira uye kuderedza huwandu hwemvura yakasviba. Pakusefa, inogona kuvandudza kunaka kwemvura yakasefa uye kuwedzera kushanda zvakanaka kwesefa.
Kuti ikwanise kucheneswa, inogona kuvandudza kushanda zvakanaka kwehuwandu uye kukurumidzisa mwero wekudonha kwemvura. Inoshandiswa pakucheneswa kwemvura, ichideredza kukosha kweSS uye kusvibiswa kwemvura yakabatwa uye inovandudza mhando yetsvina.
