Ndi mankhwala ati omwe amagwiritsidwa ntchito pokwapula?

Gwedezandi njira yolembedwa m'mafakitale osiyanasiyana, makamaka m'madzi amadzi ndipo chithandizo chamadzi, kuphatikizira tinthu tating'onoting'ono ndi ma colloids mu tinthu tating'onoting'ono tomwe timayika. Izi zimathandizira kuchotsedwa kwawo kudzera mu stoner kapena kusefa. Othandizira mankhwala omwe amagwiritsidwa ntchito pakufuta amadziwika kuti maluwa. Chimodzi mwazinthu zogwiritsidwa ntchito kwambiri komanso zogwiritsidwa ntchito kwambiri ndi polyacirramide.

Polyacrylamidendi polymer contrasizeted kuchokera ku ma acrylamide monomers. Imakhala m'njira zosiyanasiyana, kuphatikiza anionic, chikumbumtima, komanso osakhala ionic, iliyonse yomwe ili ndi mapulogalamu enaake. Kusankha kwa mtundu wa polyacrylamide kumatengera mtundu wa tinthu tating'onoting'ono m'madzi ndi zotsatira zomwe mukufuna kusintha.

Anionic Pulyacrylamide imayimbidwa mlandu ndipo nthawi zambiri imagwiritsidwa ntchito pochiza zinyalala zokhala ndi dongo komanso zinthu zachilengedwe. Kuphatikizika kwa polyacrrylamide, kumayimbidwa mlandu ndipo kumathandiza kuchiritsa madzi ndi tinthu tating'onoting'ono tomwe timayimilira. Osakhala a Polyacrylamide alibe lamulo ndipo ndi woyenera kukweza tizinthu zosiyanasiyana.

Polyacrylamide mabotolontine amagwira ntchito pomapangira pansi pa tinthu tating'onoting'ono, ndikupanga milatho pakati pawo, ndikupanga okalamba akuluakulu. Zomera zomwe zimapangitsa ndizosavuta kukhazikitsa kapena kuziseka m'madzi. Polyacrylamide amasankhidwa chifukwa cha kulemera kwake kwamwala, komwe kumawonjezera mphamvu zake zopumira komanso zowonjezera.

Kupatula polyacrlana, mankhwala ena amagwiritsidwanso ntchito pofuna kukwera, kutengera zosowa zina za chithandizo. Maluwa oyambira, mongaAluminium sulfate(Alum) ndi Ferric Cloride, amagwiritsidwa ntchito m'madzi. Mankhwala awa amapanga zitsulo zazitsulo za phompho powonjezera madzi, pothandizira kuchotsedwa kwa tinthu tating'onoting'ono.

Makamaka, makamaka, amagwiritsidwa ntchito kwambiri pofotokozera madzi kwa zaka zambiri. Mukawonjezera madzi, alum amapezeka hydrolysis, ndikupanga aluminium hydroxide maboti omwe amapezera zosayera. Mabondowo amatha kukhazikika, ndipo madzi omveka bwino amatha kudzipatula ndi zikopa.

Kudzikwapuka ndi gawo lovuta kwambiri m'madzi mankhwala amadzi njira, ndikuwonetsetsa kuti zodetsa ndi kupanga madzi oyera. Kusankha kwa Boccoclant kumadalira zinthu monga momwe madzi amagwiritsidwiredwera, mtundu wa tinthu tating'onoting'ono, ndi zotsatira zomwe mukufuna. Polyacrylamide ndi mafunde ena amagwira ntchito yofunika kwambiri yopititsa patsogolo mphamvu yamadzi ndi njira zochizira madzi, zomwe zimathandizira pakupereka madzi otetezeka komanso ofunikira osiyanasiyana.
