1, whakarite oPAM karekauotinga: i roto i te whakamahi, me rewa, ka whakamahi, kia tino rewa, ki te tāpiri ki te wai para o te concentrator.Kaua e maka tika te polyacrylamide totoka ki roto i te puna parakaingaki, ka nui te ururua o nga raau taero, ka piki ake te utu mo te maimoatanga.
2, PAM floctant dissolution huru pāmahana me te uara PH: i roto i te rewa, me rewa i roto i te wai i te pāmahana rūma, waikawa kaha, alkali, kukū tiketike, tote tiketike, e kore e pai te wai para mo te whakakorenga o te polyacrylamide, enei kounga wai. ka tino pa ki te whakamahi polyacrylamide o te paanga o te rerenga rerenga.Me tohu ko te pāmahana wai kaore e neke ake i te 50 nga nekehanga Celsius ka rewa te polyacrylamide.Ko te nui o te pāmahana wai ka whakatairanga i te paheketanga waiariki o te polyacrylamide, na reira ka pa ki tete pupuhime te paanga parataiao.
3, te whiriwhiringa o te ipu whirihoranga polyacrylamide: i roto i te whakakorenga, ka rere te tank whakakorenga mai i tetahi waahi, ki te karo i te whakakorenga o te taputapu whakaoho kia nui rawa te kaha, ka makahia te wai, ka puta he ururua.
4, PAM karekauōwehenga whirihoranga otinga: i roto i te whakakorenga o te ōwehenga whirihoranga ko te tikanga 1‰-3‰.Arā, kotahi tana wai, me te 1kg matūriki polyacrylamide totoka.Mēnā he nui rawa te kukū, ka pōturi te tere o te rewa, ka roa rawa te wā whakarewa.Mena he iti rawa te kukū o te whirihoranga, ka piki ake te maha o nga mahi a nga kaimahi.I te mea he tiketike rawa te kukū o te wai parapara maina kua tohua, kaore e taea e tenei kukū iti o te wai polyacrylamide te whakatutuki i nga whakaritenga maimoatanga, na te mea ko te maimoatanga o te kounga wai kaore e eke ki te paerewa.
5, me whakakorikori tonu te whakarite otinga: ko te tukanga o te huri i te whakakorikori mo te whakakorikori.Ringihia te polyacrylamide kua paunatia kia taurite me te mea e tika ana ki te taha o te taha o te porowhita ka puta ma te whakakorikori.Kaua e hohoro te ringihia ki roto i te wa kotahi, ka puta he maha o nga "kanohi ika", ko enei "kanohi ika" he polyacrylamide he nui te wai i puta mai i te wa kotahi, ko enei "kanohi ika" he tino uaua. ki te memeha, na ehara i te moumou rongoa anake, ka aukatia ano te paipa rongoa.
6,Te tere whakaoho: ko te tere raina o te pito o te mata whakaranu kaua e neke ake i te 8 m/s, kia kore ai e paheke te polyacrylamide.Ko te tere o te whakaoho kia kaua e iti rawa, kia kore ai e whakamutua nga matūriki polyacrylamide i runga i te mata o te wai, kia whakakorehia nga agglomerates me te whakanui ake i te uaua o te whakakore.
7, te wa ranu: me whakaoho te polyacrylamide mo te neke atu i te hawhe haora ki te tino memeha, ka kore he micelle ma i roto i te tank whakaranu, ka tino memeha te polyacrylamide.
8, anake te tino rewa PAM flocculant, i roto i te tikanga ki te purei ona ake rerenga flocculation mōrahi.Na reira, i te wa e whakamahia ana, me whakatuwherahia te taputapu whakaoho i nga wa katoa, kaore e taea anake te whakarite i te whakakorenga katoa o te polyacrylamide, engari ano hoki te whakanui ake i te pehanga ki te ngongo tarukino, te whakatere i te rerenga o te rongoa wai.
9, whirihoranga o te otinga PAM flocculant, e kore e taea te whakamahi i te whakawhiti papu centrifugal, kia kore ai e tere tere te hurihanga o nga matatahi na te whakahekenga kutikuti o te polyacrylamide.
10, me whakamahi te otinga polyacrylamide inaianei, te ra o te whirihoranga o te otinga pai, he pai ki te whakamahi i roto i nga haora 48.Mena ka roa te whakamau i te otinga polyacrylamide, ka heke haere te rerenga me te ua.
11, i muri i te tango i te kaihoko PAM flocculation, me here tonu te putea putea polyacrylamide, kaua e waiho kia makuku, ka kitea ki te ra me te whakapiri atu ki te hau mo te wa roa, na he mea ngawari ki te hanga polyacrylamide hydrolysis, kore. .
12, tango PAM flocculant, ki te whakamahi i kirihou, karaihe, ranei ipu kowiri tira, e kore e taea te whakamahi ipu rino, he mea tenei no te rino katote te take o katoa polyacrylamide matū degradation o te whakakōkī, ka arahi ki polyacrylamide rahunga.Na reira, i roto i te whirihoranga polyacrylamide, te whakawhiti, te rokiroki, ngana ki te karo me te whakapiri rino.
13, PAM flocculant tiaki: polyacrylamide i roto i te rokiroki, e kore e taea te whai wāhi ki te ra, haukū, teitei tunu tunu, wai me te pera i runga i.E rua tau te roa o tona oranga.
Ko nga tohu tekau ma toru i runga ake nei he waahanga o nga tohutohu mahi i whakahiatohia e nga kaimahi hangarau o to taatau kamupene i runga i nga korero me nga urupare a te kaihoko o mua.Ma te mahi anake i runga i te tikanga tika, ka taea e te polyacrylamide te whakatutuki i te painga pai rawa atu, a ko tana inenga ko te tino porowini.Ko te tumanako ki etahi kaiwhakamahi whakapā hou ki te awhina me te whakamarama!
I roto i te concentrator, ko te whakamahinga o te polyacrylamide he momo anionic, he momo kore-ionic ranei, he rereke te tukanga concentrator, te taiao me etahi atu mea i raro i te awe o te whakamahinga o te paanga o te raina cationic iti he pai ake, koinei te hiahia mo nga whakamatautau taiwhanga me nga whakamatautau rorohiko. ki te whakatau.
