Ndi zofunikira zolimba zotetezera chilengedwe komanso zovuta zomwe zikuchulukirachulukira pakukonza madzi otayira m'mafakitale, polydimethyldiallylammonium chloride (PDADMAC, njira ya mankhwala: [(C₈H₁₆NCl)ₙ])(https://www.cleanwat.com/poly-dadmac/)ikukhala chinthu chofunikira kwambiri. Kapangidwe kake kogwira ntchito bwino kothira madzi, kugwiritsidwa ntchito bwino, komanso kusamala chilengedwe kwapangitsa kuti igwiritsidwe ntchito kwambiri poyeretsa madzi ndi kuyeretsa madzi otayira.
Chiyambi cha Zamalonda
Polimayi ili ndi magulu amphamvu a cationic ndi magulu ogwira ntchito okhuta. Kudzera mu kuletsa mphamvu ya magetsi ndi kutsekereza madzi, imasokoneza ndikusuntha tinthu tomwe timasungunuka m'madzi ndi zinthu zosungunuka m'madzi zomwe zili ndi magulu omwe ali ndi mphamvu zoyipa m'madzi, zomwe zimasonyeza kuti ndi yothandiza kwambiri pakuchotsa utoto, kuyeretsa, komanso kuchotsa zinthu zachilengedwe. Chogulitsachi chimafuna mlingo wochepa, chimapanga ma floc akuluakulu, chimakhazikika mwachangu, ndikupanga matope ochepa otsala, zomwe zimapangitsa kuti pakhale matope ochepa. Imagwiranso ntchito mkati mwa pH yosiyana ya 4-10. Ndi yopanda fungo, yopanda kukoma, komanso yopanda poizoni, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito poyeretsa madzi ndi madzi otayira osiyanasiyana.
Mafotokozedwe Abwino
| Chitsanzo | CW-41 |
| Maonekedwe | Madzi owala mpaka achikasu opepuka, owonekera bwino, komanso okhuthala. |
| Kuchuluka kwa zinthu zolimba (%) | ≥40 |
| Kukhuthala (mPa.s, 25°C) | 1000-400,000 |
| pH (1% yankho lamadzi) | 3.0-8.0 |
| Zindikirani: Zogulitsa zokhala ndi zinthu zolimba komanso zokhuthala zosiyanasiyana zitha kusinthidwa malinga ndi pempho. | |
Kagwiritsidwe Ntchito
Mukagwiritsa ntchito yokha, muyenera kukonzekera mankhwala oyeretsera. Kuchuluka kwa mankhwala nthawi zambiri kumakhala pakati pa 0.5% ndi 5% (ponena za kuchuluka kwa zinthu zolimba).
Pochiza madzi ndi madzi otayidwa osiyanasiyana, mlingo uyenera kudziwika kutengera kukhuthala ndi kuchuluka kwa madzi oyeretsedwa. Mlingo womaliza ukhoza kudziwika kudzera mu mayeso oyesera.
Malo owonjezerapo ndi liwiro losakaniza ziyenera kusankhidwa mosamala kuti zitsimikizire kuti zinthuzo zikusakanikirana mofanana komanso kupewa kusweka kwa floc.
Kuwonjezera kosalekeza ndikobwino.
Mapulogalamu
Pakuyandama, imatha kusintha kwambiri magwiridwe antchito a makina ndikuchepetsa kuchuluka kwa madzi otuluka mumtsuko. Pakusefa, imatha kusintha khalidwe la madzi osefedwa ndikuwonjezera magwiridwe antchito a makina osefedwa.
Kuti madzi azigwiritsidwa ntchito bwino, zimathandiza kuti madzi azigwiritsidwa ntchito bwino komanso kuti madzi azigwiritsidwa ntchito bwino. Zimathandiza kuti madzi azigwiritsidwa ntchito bwino, zomwe zimathandiza kuti madzi azigwiritsidwa ntchito bwino komanso kuti madzi azithiridwa bwino komanso kuti madzi azituluka bwino.
