Izizathu zokuwohloka kwepolyacrylamide kunye nezisombululo:
Isizathu sokuqala: i-polyacrylamide njengepolymer eziphilayo kunye ne-polymer, kunye neqela elihle lemfuza, ngenxa ye-adsorption eqinile ye-flocculation, ukuba indawo ye-Yin efumileyo, kulula ukufunxa ukufuma kwaye yenze ibhloko, ngakumbi imvula enkulu kakhulu, imimandla yemozulu efumileyo. , ngakumbi kulula ukubangela i-metamorphism.
Isisombululo: ukugcinwa kwepolyacrylamide kwindawo epholileyo kunendawo efumileyo, kwangaxeshanye ngaphakathi endlini kufuneka kugcinwe umlinganiselo othile wokungena komoya, ukuba kuyanetha kufuneka itywinwe ngokungqongqo, ngokufutshane, ungaqhagamshelani nolwelo olunxulumene namanzi.
Isizathu sesibini: Emva kokusetyenziswa kwe-polyacrylamide, ngenxa yomsebenzi oxakekileyo, ixesha lokulibala ukuvula isikhwama se-polyacrylamide ukuba sibambe kwakhona, kubangele ukufunxa kwamanzi e-polyacrylamide emoyeni kunye nokuwohloka.
Isisombululo: kungakhathaliseki ukuba nini kwaye phi, ukuba nje uvule isikhwama sokupakisha se-polyacrylamide, ngokukhawuleza ukusonga, unganiki umoya ithuba elincinane, ungangeni moya.
Isizathu sesithathu: ubomi beshelufu ye-polyacrylamide iphelelwe lixesha, nangona ukusetyenziswa kwe-polyacrylamide ubomi bayo beshelufu ayifani, kodwa ukuphela kobomi beshelufu, konke akuvumelekile.
Isisombululo: Nayiphi na into inobomi obuthile beshelufu, ukongeza kubomi beshelufu, ke nokuba amanyathelo okhuseleko ukwenza kwakhona angqongqo, akuncedi, kuba ukongeza kundoqo wengxaki, ngaphandle kulandelwa ngabachaphazelekayo, kucetyiswa ukuba ungathengi i-polyacrylamide eninzi, ngokukhawuleza uphelelwe ukuthenga, ungafaki i-polyacrylamide ixesha elide kuloo nto.
Isizathu sesine: Polyacrylamide akazange naziphi na iingxaki, kodwa emva koqwalaselo ngempumelelo isisombululo Polyacrylamide, iiyure ezingaphezu kwama-24, oko kukuthi, kwiiyure ezingama-24 akazange asebenzise isisombululo Polyacrylamide.
Isisombululo: Ukuthetha ngokuthe ngqo, okoko nje uqwalaselo oluyimpumelelo lwesisombululo se-polyacrylamide, kufuneka lusetyenziswe ngokukhawuleza kwiiyure ezimbalwa, kuba ixesha lokugcina emva koqwalaselo lwesisombululo lilinganiselwe, kungenjalo i-hydrolysis ye-polyacrylamide reaction hand to the impact, it kucetyiswa ukuba isetyenziswe kwiiyure ezingama-24.
Ngokutsho kophando lweengcali ukuba ixesha elisebenzayo le-polyacrylamide li-1 ixesha lonyaka, ukuba ngaphezu kweli xesha, ngubani nceda uze phezu kwamampunge, kungekuphela nje ilahleko yemali kunye nezinto eziphathekayo, kwaye unokulibazisa ixesha lokwakha.
Ukugcinwa okuchanekileyo kwe-polyacrylamide
Umhla wokuphelelwa lixesha yindalo yawo onke amanqaku, kwaye kuyafana nakwiarhente zokucoca amanzi.Kungakhathaliseki ukuba iqinile okanye i-liquid, umhla wokuphelelwa yisikhathi udlulile, kwaye umngcipheko wokungaphumeleli uphezulu kakhulu.Ke uyazi njani ukuba i-polyacrylamide iyasilela?
Malunga polyacrylamide, iintlobo ezahlukeneyo polyacrylamide, ixesha kwishelufa yahlukile.Oku kuninzi malunga nesakhiwo sayo, ixesha lokuqinisekiswa kwe-anionic polyacrylamide limalunga neminyaka emi-2, ubomi beshelufu ye-cationic polyacrylamide ngunyaka o-1.Ukuba umhla wokuphelelwa kwexesha ugqithisiwe, umhla wokuphelelwa kwexesha unokuphelelwa.
Indawo yokugcina i-polyacrylamide inempembelelo enkulu kubomi bayo beshelufu.Ubomi beshelufu yepolyacrylamide inokwandiswa kwindawo engena umoya, eyomileyo nepholileyo.Kwimeko yobushushu obuphezulu kunye nokufuma, ubomi beshelufu yepolyacrylamide bufutshane.
Kweminye imimandla, ngenxa yemozulu efumileyo, ezinye izityalo zogutyulo lwe-polyacrylamide yokuqokelela ixesha elide, umlomo wokupakisha awunamandla, i-hygrophilic caking, ngenxa ye-caking ye-polyacrylamide flocculant, abantu abaninzi banemibuzo malunga nokuba ayisebenzi.Ke ngoko, ukungaphumeleli kwepolyacrylamide kunokugwetywa kwimiba emibini.Okokuqala, i-viscosity iyancitshiswa, kwaye umphumo we-flocculation ubi xa usetyenziswa.
Indlela echanekileyo yokugcina i-polyacrylamide:
I-1, i-polyacrylamide yokugcina, kufuneka igcine indawo evaliweyo, yomile, igweme ukukhanya, ithintele ubushushu obuphezulu, igweme ukufunxa ukufuma, ukubola kunye nokuwohloka.
2, ixesha lokugcina i-polyacrylamide akufanele libe lide kakhulu.Kungenjalo, kuya kukhokelela ekwaluphaleni ukubola, ngokuqhelekileyo i-concentration encinci, elifutshane ixesha lokuqinisekisa.
I-3, i-polyacrylamide flocculant kunye ne-ion zetsimbi eziphezulu kulula ukuvelisa ijeli enganyibilikiyo, ngoko ke akufanele igcinwe ngokuqhagamshelana ngqo nezikhongozeli zentsimbi ixesha elide.
Ngoko ke, sitshintsha indawo yokugcina i-polyacrylamide.Ubushushu ngumba obalulekileyo.Iqondo lokushisa lokugcina kufuneka lilawulwe ngokungqongqo ngaphantsi kwe-50 degrees ukukhusela ukubonakaliswa okuthe ngqo.Okwesibini, umlinganiselo omncinci wokuzinzisa unokufakwa kwisisombululo se-polyacrylamide, njenge-sodium thiocyanate, i-thiurea, i-nitrite ye-sodium kunye ne-methanol enganyibilikiyo, ukwenza isisombululo se-polyacrylamide sizinzile.
