Izizathu zokuwohloka kwe-polyacrylamide nezixazululo:
Isizathu sokuqala: i-polyacrylamide njenge-polymer ephilayo kanye ne-polymer, eneqembu elihle lofuzo, ngenxa ye-adsorption eqinile ye-flocculation, uma indawo enomswakama ye-Yin, kulula ukumunca umswakama futhi yakhe ibhulokhi, ikakhulukazi imvula ethile ikhulu kakhulu, izindawo zezulu ezinomswakama. , ikakhulukazi kulula ukubangela i-metamorphism.
Isixazululo: isitoreji se-polyacrylamide endaweni epholile kunendawo emanzi, ngesikhathi esifanayo endlini kufanele igcine inani elithile lokungena komoya, uma lina kufanele livalwe ngokuqinile, ngamafuphi, ungaxhumani noketshezi oluhlobene namanzi.
Isizathu sesibili: Ngemuva kokusetshenziswa kwe-polyacrylamide, ngenxa yomsebenzi omatasatasa, isikhathi sokukhohlwa ukuvula isikhwama se-polyacrylamide ukuze sibambe futhi, okuholela ekumunceni kwamanzi e-polyacrylamide emoyeni nokuwohloka.
Isixazululo: kungakhathaliseki ukuthi nini futhi kuphi, inqobo nje uma uvula isikhwama sokupakisha se-polyacrylamide, ukusonga ngokushesha, unganiki umoya ithuba elincane, ungangeni moya.
Isizathu sesithathu: impilo yeshalofu ye-polyacrylamide iphelelwe yisikhathi, nakuba ukusetshenziswa kwe-polyacrylamide ukuphila kwayo kweshalofu akufani, kodwa ukuphela kwesikhathi sokuphila kweshalofu, konke akuvumelekile.
Isixazululo: Noma iyiphi into has a yokuphila ethile eshalofini, ngaphezu ukuphila eshalofini ke ngisho noma izinyathelo zokuvikela ukwenza futhi eqinile, akusizi, ngoba ngaphezu okushiwo inkinga, ngaphandle kulandelwa abathintekile, it. Kunconywa ukuthi ungathengi i-polyacrylamide eningi, ngokushesha uphelelwe ukuthenga, ungafaki i-polyacrylamide yesikhathi eside kulokho.
Isizathu sesine: Polyacrylamide akazange abe nezinkinga, kodwa ngemva ukucushwa ngempumelelo polyacrylamide isixazululo, amahora angaphezu kuka-24, okungukuthi, kungakapheli amahora angu-24 akazange asebenzise isisombululo polyacrylamide.
Isixazululo: Uma ngikhuluma ngokuqinile, inqobo nje uma ukucushwa ngempumelelo kwesixazululo se-polyacrylamide, kufanele kusetshenziswe ngokushesha phakathi namahora ambalwa, ngoba isikhathi sokugcina ngemuva kokucushwa kwesixazululo sinqunyelwe, ngaphandle kwalokho i-hydrolysis yesandla sokusabela se-polyacrylamide kumphumela, Kunconywa ukuthi isetshenziswe kungakapheli amahora angama-24.
Ngokusho kocwaningo lochwepheshe ukuthi isikhathi esisebenzayo se-polyacrylamide singu-1 isikhathi sonyaka, uma ngaphezu kwalesi sikhathi, ngubani ocela ukudlula akusizi, hhayi nje ukulahlekelwa kwezimali nezinto ezibonakalayo, futhi kungase kubambezele isikhathi sokwakha.
Ukulondolozwa okulungile kwe-polyacrylamide
Idethi yokuphelelwa yisikhathi iwuhlobo lwazo zonke izindatshana, futhi kuyafana nakuma-ejenti okuhlanza amanzi.Kungakhathaliseki ukuthi iqinile noma iwuketshezi, idethi yokuphelelwa yisikhathi isidlulile, futhi ingozi yokwehluleka iphezulu kakhulu.Ngakho-ke ubona kanjani ukuthi i-polyacrylamide iyehluleka?
Mayelana ne-polyacrylamide, izinhlobo ezahlukene ze-polyacrylamide, isikhathi sokuphila kweshalofu sihlukile.Lokhu kuhlobene kakhulu nesakhiwo sayo, isikhathi sokusebenza kwe-anionic polyacrylamide cishe iminyaka emi-2, impilo yeshalofu ye-cationic polyacrylamide ingunyaka ongu-1.Uma idethi yokuphelelwa yisikhathi yeqiwe, idethi yokuphelelwa yisikhathi ingase iphelelwe yisikhathi.
Indawo yokugcina i-polyacrylamide inethonya elikhulu empilweni yayo yeshalofu.Impilo yeshelufu ye-polyacrylamide inganwetshwa endaweni enomoya, eyomile futhi epholile.Ezingeni eliphezulu lokushisa nendawo enomswakama, impilo yeshalofu ye-polyacrylamide ifushane.
Kwezinye izindawo, ngenxa yesimo sezulu esinomswakama, ezinye izitshalo zendle zokuqoqwa kwe-polyacrylamide isikhathi eside, umlomo wokupakisha awunamandla, u-hygrophilic caking, ngenxa ye-caking ye-polyacrylamide flocculant, abantu abaningi banemibuzo mayelana nokuthi ayivumelekile yini.Ngakho-ke, ukwehluleka kwe-polyacrylamide kungahlulelwa ezicini ezimbili.Okokuqala, i-viscosity iyancishiswa, futhi umphumela we-flocculation umpofu uma usetshenziswa.
Indlela efanele yokugcina ye-polyacrylamide:
1, isitoreji se-polyacrylamide, kufanele sigcine imvelo ivaliwe, yomile, igweme ukukhanya, ivimbele izinga lokushisa eliphezulu, igweme ukumuncwa komswakama, ukubola nokuwohloka.
2, isikhathi sokugcina se-polyacrylamide akufanele sibe side kakhulu.Uma kungenjalo, kuzoholela ekwakhiweni kokuguga, ngokuvamile ukugxilisa kancane kancane, isikhathi sokufaneleka sibe sifushane.
I-3, i-polyacrylamide flocculant kanye ne-ion yensimbi ephezulu kulula ukukhiqiza ijeli engancibiliki, ngakho-ke akufanele igcinwe ngokuxhumana okuqondile neziqukathi zensimbi isikhathi eside.
Ngakho-ke, sishintsha indawo yokugcina ye-polyacrylamide.Izinga lokushisa liyisici esibalulekile.Izinga lokushisa lokugcina kufanele lilawulwe ngokuqinile ngaphansi kwamadigri angu-50 ukuvimbela ukuchayeka okuqondile.Okwesibili, inani elincane lokuqiniswa lingangezwa kusixazululo se-polyacrylamide, njenge-sodium thiocyanate, i-thiurea, i-sodium nitrite ne-non-solvent methanol, ukwenza isisombululo se-polyacrylamide sizinze.
