Chii chinonzi Nonionic Polyacrylamide?
Nonionic Polyacrylamide (NPAM)ndeye polymeric flocculant ine magetsi asina kwaakarerekera mamorekuru cheni. Inoratidzira huremu hwemamorekuru uye yakakura pH kushivirira siyana, ichiendesa kunoshanda kucheneswa kwemvura uye flocculation zvichibva pane yayo yakasarudzika mabhenefiti.Kusiyana neiyo ionic flocculants, NPAM haivimbe nechaji neutralization kushanda. Pane kudaro, inonyanya kuunganidza tsvina kuburikidza neadsorption bridging, mambure / kutsvaira, uye molecular cheni entanglement, kuendesa yakanakisa flocculation kuita kweakasiyana inorganic yakamiswa zvimedu.Nekuchinjika kwakasimba, NPAM inoshandiswa zvakanyanya mukusarerekera uye isina kusimba acidic marara emarara. Inobatisawo zvakanaka-madhaka ekuchajisa, nzvimbo dzemvura dzakarembera, uye-organic-yakakwirira sewage.
Chii chinonzi Amphoteric Polyacrylamide?
Amphoteric Polyacrylamide inoratidzira ese ari maviri anionic uye cationic anochaja mapoka pane ayo mamorekuru cheni, achibatanidza kubhadharisa neutralization zvimiro zve cationic PAM neye adsorption bridging mechanism yeanionic PAM. Izvi zviviri zvinoshanda zvinopa kuchinjika kwakakura kupfuura kwakajairwa PAM mamakisi.Inokunda mukubata yakaoma, inosiyana mamiriro emvura, ine yakasarudzika munyu kushivirira uye kugadzirisa kugadzikana. Yakanyanya kunaka-yakakodzera mamiriro emvura anochinja-chinja, madhaka asina kugadzikana, uye zvinhu zvinosvibisa zvakasanganiswa. Zvakaoma-ku{6}}kuchenesa nzizi dzemvura yetsvina dzakadai semvura yetsvina ine mafuta uye{7}}mvura ine munyu mukuru, kushanda kwayo uye mibairo yacho kupfuura nonionic polyacrylamide.
Misiyano Yakakosha Pakati peNonionic neAmphoteric Polyacrylamide
1. Different Molecular Charge Structures
Nonionic polyacrylamide inotakura chero isingabhadharise uye inotsamira zvakanyanya pakushambadza kwemuviri kwekuyerera. Amphoteric polyacrylamide, nekusiyana, ine zvese zvakanaka uye zvisina kunaka machaji, zvichiita kuti zvese zviri zviviri kuchaja kusarerekera uye bhiriji mhedzisiro. Kuzvitaura zviri nyore: nonionic PAM inoita senge "binder," nepo amphoteric PAM inoshanda se "yakangwara inoumba flocculant."
2. Yakasiyana Adaptability kune Yakaoma Mvura Hunhu
Nonionic PAM inonzwa zvakanyanya kushanduka kwepH, salinity, uye zvinosvibisa, zvichiita kuti uite kusagadzikana mumamiriro ezvinhu akasiyana. Nekuda kwechimiro chayo che-chaji, amphoteric PAM inopa kusawirirana kwemunyu kwakasimba uye-kugona kuvhiringa, zvichiita kuti ienderane nekuoma, nekushanduka kwenzvimbo dzemvura.
3. Different Sludge Dewatering Performance
Nonionic PAM inongotsamira pane bhiriji remuviri kuti riunganidze sludge zvimedu, zvichikonzera kushomeka kwekushanda kwemasludge ane machaji akaomarara. Amphoteric PAM inogadzirisa zvese zvakanaka uye zvisina kunaka kubhadharisa mune sludge colloids uku ichigadzira gobvu, flocs yakasimba. Izvi zvinounza makeke akadirwa mvura ane hunyoro hwakaderera uye yepamusoro pese kugadzirisa kunyatsoita.
Ndeapi Maindasitiri Ari Nonionic uye Amphoteric Polyacrylamide Yakakodzera?
1. Nonionic Polyacrylamide (NPAM)
Nekuda kwemaitiro ayo emagetsi asina kwaakarerekera, kushivirira kwakafara pH, uye yakasimba adsorption bridging kugona kune inorganic yakamiswa zvimedu, yakanakira:
- Municipal tsvina yemvura: Kunyanya kune isina kwayakarerekera kana isina kusimba acidic masewage ekanzuru uye yakaderera-charge sludge.
- Kucheneswa kwemvura muzvidyarwa zvemvura: Kubvisa zvimisikidzwa zvakamiswa kubva mumvura yakasvibira kuti zvive pachena.
- Kugadziriswa kwemvura yetsvina mugodhi: Kurapa mvura yemumigodhi ine zvidimbu zvisingaite kuti zvinyatso patsanura -mumvura.
- Indasitiri yemapepa: Inoshandiswa sekuchengetedza uye zviyamuro zvemvura mu pulp, uye nekujekeswa kwemvura chena, yakakodzera kusarerekera kune isina kusimba acidic pulp masisitimu.
- Indasitiri yekudhaya machira: Kurapa{{0}mushonga wedhayi dhayi shoma uye mvura ine tsvina isina asidhi yakasimba kana alkalis.
- Chikafu kugadzirisa tsvina yemvura: Yakakodzera kucheneswa kwetsvina ine yakakwira organic yemukati uye sludge dewatering.
2. Amphoteric Polyacrylamide (AMPAM)
Nemagadzirirwo ayo-kuchajisa, inoshingirira munyu, uye kuenderana nemamiriro emvura akaomarara, inokunda mumaindasitiri anotevera:
- High-kugadziriswa kwemvura yetsvina ine munyu/mafuta: Kuyerera nekubvisa matope panzvimbo yemafuta anogadzirwa mvura, kunatsa tsvina ine mafuta, uye -mushonga wemunyu wakakura.
- Yakaomarara maindasitiri emvura yetsvina: Kubata kemikari uye yemishonga tsvina ine tsvina iripo pamwe chete uye inochinja-chinja mhando yemvura.
- Municipal sludge dewatering: Kuendesa hunyoro hushoma mumakeke akacheneswa nokuda kwepamusoro-organic, complex sludge.
- Kugeza marasha/kuchenesa mvura yetsvina nemakemikari: Kurapa-kuoma, -nemunyu wakawanda wekugeza mvura yetsvina uye yekubikira mvura yetsvina.
- Dehwe / machira emarara emvura kurapwa: Kugadzira tsvina yeindasitiri uye sludge ine akasiyana ekuwedzera uye yakaoma mhosva.
- Special industrial solid solid-liquid separation: Kunyatsobvisa mvura kwemasara emugodhi uye madhaka emumaindasitiri anooneka.
Nzira Yekusarudza Ndeipi Yekusarudza?
Vatengi vazhinji vanotanga nekubvunza kuti: "Ndoenda neanionic kana nonionic PAM?" "Chii chinonzi ionic degree?" "Huremu hwemamorekuru hwakakwira zvakadii?" Muchokwadi, izvi zvinongori zvekutanga zvigadzirwa paramita. Kiyi yechokwadi yekuyerera inobudirira iri pakuti chigadzirwa chinoenderana nezvako here -panzvimbo yekushanda mamiriro ezvinhu. Mvura pH, conductivity, salinity, uye tembiricha, pamwe chete nemakemikari ekugadzirisa, dosing points, pre{3}}kemikari yekurapa, uye kusanganisa simba, zvese zvinokanganisa mhinduro yekupedzisira. Zviitiko zvizhinji zvekusashanda zvakanaka kwekurapa hazvikonzerwi nenyaya dzemhando yechigadzirwa, asi zvikanganiso zvinowanzoitika-zvakadai sokuwedzera polima isati yanyungudutswa uye yakura, kana kushandisa musanganiswa wakawandisa unopwanya ma flocs.
Zvakajairwa Zvikanganiso muPAM Sarudzo
- Kuvimba chete nemaparameta (molecular weight, ionic degree) pasina-saiti bvunzo dzechirongo
- Kusarudza kunoenderana chete ne "indasitiri tsika" kana mutengo, uchiregeredza chaiwo mamiriro emvura
- Kusakwana kwekugadzirira kwepolymer (kuparara kusina kukwana, kusanganiswa kwakanyanya) zvichiita kuti kusashanda kurapwa
Ramangwana Trend: Kukwidzwa kweBlended uye Yakagadzirirwa PAM
Sezvo maindasitiri emvura yetsvina maumbirwo achikura zvakanyanya kuoma, generic PAM mamakisi haachakwanise kuzadzisa zvese zvinodiwa. Yakasanganiswa uye yakagadziridzwa PAM, yakarongedzwa kune chaiyo mvura uye sludge maitiro, iri kuve iyo indasitiri chiyero chepamusoro kunyatsoshanda uye kuderera kwese kushandiswa kwemakemikari.
Mhedziso
Hapana "imwe-saizi-inokwana-ese" PAM yemapurojekiti ekuchenesa mvura. Kunyange mhando imwe chete yepolyacrylamide inogona kuunza mhedzisiro yakasiyana zvikuru zvichienderana nemhando yemvura, sludge maitiro, uye maitiro ekugadzirisa. Amphoteric polyacrylamide, kune rumwe rutivi, inobudirira mumamiriro ezvinhu akaoma, kunyanya mumafuta, -munyu, uye maitiro emvura akasiyana-siyana apo inopa kushanda kwakafanana. Kazhinji, kubudirira kwekurapa kunobva kwete pachigadzirwa chacho, asi kuti kusarudzwa kunopindirana ne{8}}nzvimbo yako yekushanda. Panzvimbo pekungotarisa pamutengo kubva pakutanga, zvinonyanya kushanda kuti utange wajekesa maitiro ako emvura yakaraswa, zvinangwa zvekurapa, uye maparamendi ekushanda, wobva wasimbisa mashandiro nemajagi bvunzo. Iyi yemaitiro ekuita inochengetedza nguva yakakosha uye dambudziko mukushanda{11}}kwenguva refu.
Kana uri kuchenesa mvura yetsvina ine mafuta, tsvina yemakemikari, tsvina yekanzuru, kana kuti{0}}mvura ine munyu yakakwira mumaindasitiri uye wakatarisana nekusagadzikana kwePAM kushanda, kushandiswa kwemakemikari kwakanyanya, kana kuoma kwemarara, tinokukokataura neGreen Chemicalkuti tikurukure nezve-nzvimbo yako yekushanda. Zvichienderana nemhando yako yemvura yakaraswa, nzira yekurapa, uye kugadzirwa kwemidziyo, tinogona kubatsira nePAM kusarudzwa, kuongororwa kwechirongo chekuongorora, uye kurudziro yekushandisa kukubatsira iwe kuwana mhinduro yakakwana yezvido zvako zvekushanda.Kungogovera rudzi rwako rwemvura yakaraswa, kushandiswa kweindasitiri, kana maparameter emhando yemvura, uye timu yedu yehunyanzvi ichapa mazano anoenderana nerutsigiro rwemhinduro.
