Polyaluminum chloride (PAC)
Polyaluminum chloride (PAC), yomwe imatchedwa polyaluminum mwachidule, Poly Aluminium Chloride dosing In Water Treatment, ili ndi formula ya mankhwala ya Al₂Cln(OH)₆-n. Polyaluminum Chloride Coagulant ndi mankhwala ophera madzi a polymer omwe ali ndi kulemera kwakukulu kwa mamolekyulu komanso mphamvu yayikulu yopangidwa ndi mphamvu yolumikizira ma hydroxide ions ndi polymerization ya ma polyvalent anions. Poly Aluminium Chloride Pac imatha kugawidwa m'magulu olimba ndi amadzimadzi. Polyaluminum Yolimba yachikasu, yobiriwira imvi, ufa wa bulauni wakuda. Madzi a Pac amakhudzidwa mosavuta ndi chinyezi ndipo amasungunuka mosavuta m'madzi. Njira ya hydrolysis imatsagana ndi njira zakuthupi ndi zamankhwala monga electrochemistry, agglutination, adsorption, ndi precipitation, ndipo ili ndi mphamvu zolimba zolumikizira ma bridging.
1. Njira yogwirira ntchito
Yankho lamadzi la mankhwala a PAC ndi chinthu chopangidwa ndi hydrolysis pakati pa FeCl₃ ndi Al(OH)₃, chokhala ndi mphamvu ya colloidal, kotero chimakhala ndi mphamvu yokwanira yolowerera ku zinthu zolimba zomwe zapachikidwa m'madzi, kuti chikwaniritse cholinga chophatikiza zinthu zolimba zomwe zapachikidwa m'madzi.
2. Zinthu Zamalonda
● Polyaluminum chloride imakhala yokhazikika pa kutentha kwa chipinda, ndipo siidzawonongeka ikasungidwa kwa nthawi yayitali. Polyaluminum yolimba yomwe yawonekera imayamwa mosavuta chinyezi, koma siidzawonongeka, ndipo siili ndi poizoni komanso yopanda vuto.
● pH ya madzi oyenera ndi 4-14, koma pH ya madzi oyenera ndi 6-8.
● Ufa wa Poly Aluminium Chloride uli ndi makhalidwe monga mlingo wochepa, mtengo wotsika, ntchito yayikulu, ntchito yosavuta, kugwiritsidwa ntchito kwambiri komanso kuwononga pang'ono.
Polyacrylamide (PAM)
Polyacrylamide (PAM) /nonionic polyacrylamide/cation polyacrylamide/anionic polyacrylamide,alias flocculant No. 3, ndi polymer yosungunuka m'madzi yopangidwa ndi polymerization ya acrylamide (AM) monomer yaulere. Njira yolumikizirana ndi flocculation pochiza madzi, Polyacrylamide sds ili ndi flocculation yabwino ndipo imatha kuchepetsa kukangana pakati pa zakumwa. Kukana kumatha kugawidwa m'mitundu inayi: anionic, cationic, nonionic ndi amphoteric malinga ndi mawonekedwe a ionic.
Polyacrylamide ndi tinthu tating'onoting'ono ta ufa woyera, tomwe tingasungunuke m'madzi molingana ndi momwe timachitira, madzi amadzi ndi ofanana komanso owonekera bwino, ndipo kukhuthala kwa madzi amadzi kumawonjezeka kwambiri ndi kuwonjezeka kwa kulemera kwa mamolekyu a polima. PAM siisungunuka m'zinthu zambiri zachilengedwe monga formaldehyde, ethanol, acetone, ether, ndi zina zotero.
1. Njira yogwirira ntchito
Polyacrylamide ndi polima kapena polyelectrolyte yosungunuka m'madzi. Pali magulu angapo a polar mu unyolo wa mamolekyu a PAM, omwe amatha kuyamwa tinthu tolimba tomwe timapachikidwa mu zimbudzi, kupanga mipata pakati pa tinthu kapena kudzera mu kuletsa mphamvu, kotero kuti tinthuto timatha kusonkhana kuti tipange ma flocs akuluakulu. Chifukwa chake, polyacrylamide imatha kufulumizitsa zinthu zolimba zopachikidwa. Kusefukira kwa tinthu tating'onoting'ono kumakhala ndi zotsatira zomveka bwino pakufulumizitsa kumveka bwino kwa yankho ndikulimbikitsa kusefa.
2. Zolemba
Polyacrylamide ili ndi acrylamide monomer yopanda poizoni. Mu mankhwala akumwa omwe aperekedwa m'dziko langa, kuchuluka kovomerezeka ndi 0.01mg/L. Pofuna kupewa kuwonongeka kwa polyacrylamide, kutentha kwa madzi ake kuyenera kulamulidwa kuti kusapitirire 40°C. Pofuna kupewa kuwala kwa dzuwa, pang'ono pa zinthu zokhazikika, monga sodium thiocyanate, sodium nitrite, ndi zina zotero, zitha kuwonjezeredwa ku yankho. Ufa wolimba wa Polyacrylamide uyenera kupakidwa m'migolo yachitsulo yokutidwa ndi matumba a polyethylene osanyowa kapena wokutidwa ndi zigawo za polyethylene, ndikutsekedwa kuti usawotchedwe ndi chinyezi chambiri.
Polyacrylamide yamadzimadzi iyenera kupakidwa m'mapaketi kenako nkuyikidwa m'migolo yamatabwa kapena m'migolo yachitsulo. Nthawi yosungiramo ndi miyezi pafupifupi 3 mpaka 6. Iyenera kusunthidwa musanagwiritse ntchito. Kutentha kosungirako sikuyenera kupitirira 32°C ndipo kuchepera 0°C.
