Izizathu zokuwohloka kwepolyacrylamide kunye nezisombululo:
Isizathu sokuqala: polyacrylamide njenge polymer eziphilayo kunye polymer, kunye neqela gene gene elungileyo, ngenxa flocculation adsorption eyomeleleyo, ukuba Yin indawo efumileyo, kulula ukufunxa ukufuma kwaye wenze ibhloko, ingakumbi ezinye imvula enkulu ngokwentelekiso, iindawo zemozulu efumileyo, ingakumbi lula ukubangela 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, okukhokelela ekufunxeni 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 buphelelwe, nangona ukusetyenziswa kwe-polyacrylamide ubomi beshelufu ayifani, kodwa ukuphela kobomi beshelufu, konke akuvumelekile.
Isisombululo: Nayiphi na into inobomi beshelufa ethile, ukongeza kubomi beshelufa, ngoko ke nokuba amanyathelo okhuseleko ukwenza kwakhona engqongqo, ayincedi, kuba ukongeza kwisiseko sengxaki, ngaphandle ilandelwa ngabachaphazelekayo, kuyacetyiswa ukuba ungathengi kakhulu i-polyacrylamide, kungekudala uphume ukuthenga, ungafaki i-polyacrylamide yexesha 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: Ngokungqongqo, logama nje uqwalaselo ngempumelelo isisombululo Polyacrylamide, kufuneka isetyenziswe ngoko nangoko phakathi kweeyure ezimbalwa, kuba ixesha yokugcina emva koqwalaselo isisombululo silinganiselwe, kungenjalo i-hydrolysis ye-polyacrylamide yokusabela isandla kwimpembelelo, kucetyiswa ukuba usebenzise 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 omnye. 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 lokuqokelelwa kwepolyacrylamide ixesha elide, umlomo wokupakisha awunamandla, i-hygrophilic caking, i-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, ukugcinwa kwe-polyacrylamide, 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. Ngaphandle koko, kuya kukhokelela ekwaluphaleni kokubola, ngokuqhelekileyo ukugxininiswa kuncinci, ixesha elifutshane 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 yinto ebalulekileyo. 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-non-solvent methanol, ukwenza isisombululo se-polyacrylamide sizinzile.
