Kodi ndimasankha bwanji mtundu wa Polyacrylamide?

Polyacrylamide(PAM) nthawi zambiri imatha kugawidwa kukhala anionic, cationic, ndi nonionic malinga ndi mtundu wa ion. Iwo makamaka ntchito flocculation mu madzi mankhwala. Posankha, mitundu yosiyanasiyana yamadzi otayira ingasankhe mitundu yosiyanasiyana. Muyenera kusankha PAM yoyenera molingana ndi mawonekedwe a zimbudzi zanu. Nthawi yomweyo, muyenera kufotokozeranso njira yomwe polyacrylamide idzawonjezedwe komanso cholinga chomwe mukufuna kukwaniritsa pogwiritsa ntchito.

The luso zizindikiro za polyacrylamide zambiri monga maselo kulemera, digiri ya hydrolysis, ionicity, mamasukidwe akayendedwe, otsala okhutira monoma, etc. zizindikiro ayenera momveka bwino malinga ndi zinyalala mukuwachitira.

1. Kulemera kwa maselo / mamasukidwe akayendedwe

Polyacrylamide ili ndi zolemera zosiyanasiyana zamamolekyu, kuchokera pansi mpaka pamwamba kwambiri. Kulemera kwa mamolekyulu kumakhudza momwe ma polima amagwirira ntchito zosiyanasiyana. High molekyulu kulemera polyacrylamide zambiri zothandiza kwambiri mu ndondomeko flocculation chifukwa unyolo polima awo ndi yaitali ndipo akhoza kulumikiza tinthu zambiri pamodzi.

Kukhuthala kwa njira ya PAM ndikokwera kwambiri. Pamene ionization ndi khola, yaikulu maselo kulemera kwa polyacrylamide, ndi kukhuthala kwakukulu kwa njira yake. Izi ndichifukwa choti unyolo wa macromolecular wa polyacrylamide ndi wautali komanso woonda, ndipo kukana kusuntha mu yankho ndikokulirapo.

2. Digiri ya hydrolysis ndi iocity

The ionicity ya PAM imakhudza kwambiri momwe amagwiritsidwira ntchito, koma mtengo wake woyenera umadalira mtundu ndi mtundu wa zinthu zomwe zathandizidwa, ndipo pali mikhalidwe yosiyana siyana muzochitika zosiyanasiyana. Pamene mphamvu ya ionic ya mankhwala ochiritsidwa ndi apamwamba (zambiri zosawerengeka), ionicity ya PAM yogwiritsidwa ntchito iyenera kukhala yapamwamba, mwinamwake iyenera kukhala yochepa. Nthawi zambiri, digiri ya anion imatchedwa digiri ya hydrolysis, ndipo digiri ya ion nthawi zambiri imatchedwa digiri ya cation.

Momwe mungasankhire polyacrylamidezimadalira ndende ya colloids ndi zolimba inaimitsidwa m'madzi. Mukamvetsetsa zomwe zili pamwambapa, mungasankhire bwanji PAM yoyenera?

1. Kumvetsetsa komwe kumachokera zimbudzi

Choyamba, tiyenera kumvetsa gwero, chilengedwe, zikuchokera, olimba okhutira, etc. wa matope.

Nthawi zambiri, cationic polyacrylamide imagwiritsidwa ntchito pochiza sludge, ndipo anionic polyacrylamide imagwiritsidwa ntchito pochiza matope. Pamene pH ili pamwamba, cationic Polyacrylamide sayenera kugwiritsidwa ntchito, ndipo pamene , anionic Polyacrylamide sayenera kugwiritsidwa ntchito. Kuchuluka kwa acidity kumapangitsa kukhala kosayenera kugwiritsa ntchito anionic polyacrylamide. Pamene olimba zili sludge ndi mkulu, kuchuluka kwa polyacrylamide ntchito ndi yaikulu.

2. Kusankhidwa kwa iocity

Pakuti sludge kuti ayenera kukhala opanda madzi m`thupi mankhwala zimbudzi, mukhoza kusankha flocculants ndi ionicity osiyana kudzera zatsopano ang'onoang'ono kusankha polyacrylamide abwino kwambiri, amene angathe kukwaniritsa bwino flocculation zotsatira ndi kuchepetsa mlingo, kupulumutsa ndalama.

3. Kusankha kulemera kwa maselo

Nthawi zambiri, kukweza kwa maselo a polyacrylamide, kumapangitsanso kukhuthala kwakukulu, koma kugwiritsidwa ntchito, kumapangitsa kuti thupi likhale lolemera kwambiri la mankhwala, ndi bwino kugwiritsa ntchito zotsatira zake. Mwachindunji ntchito, yoyenera maselo kulemera kwa polyacrylamide ayenera kudziŵika monga kwenikweni ntchito makampani, khalidwe madzi ndi mankhwala zida.

Mukagula ndikugwiritsa ntchito PAM kwa nthawi yoyamba, tikulimbikitsidwa kuti mupereke mawonekedwe enieni a chimbudzi kwa wopanga flocculant, ndipo tidzakupangirani mtundu woyenera kwambiri wa mankhwala. Ndipo zitsanzo zamakalata zoyesedwa. Ngati muli ndi chidziwitso chochuluka pazakudya zanu zachimbudzi, mutha kutiuza zomwe mukufuna, malo ogwiritsira ntchito, ndi njira, kapena kutipatsa mwachindunji zitsanzo za PAM zomwe mukugwiritsa ntchito pano, ndipo tidzakufananitsani ndi Polyacrylamide yoyenera.
