1. Isishwankathelo seMveliso
Polyacrylamide isifinyezo (amide)
i-polyacrylamide (PAM)
Amasuntswana amhlophe acocekileyo
I-Polyacrylamide, ebizwa ngokuba yi-PAM, ihlukaniswe ibe yi-anionic (APAM), i-cationic (CPAM), kunye ne-nonionic (NPAM). Yipolymer ehambelanayo kwaye yenye yezona ntlobo zisetyenziswa kakhulu kwiikhompawundi zepolymer ezinyibilikayo emanzini. I-Polyacrylamide kunye ne-derivatives yayo ingasetyenziswa njenge-flocculants esebenzayo, i-thickeners, iziphuculi zephepha kunye ne-ejenti yokunciphisa ukutsalwa kwamanzi, njl., kwaye zisetyenziswa ngokubanzi kunyango lwamanzi, ukwenza iphepha, i-petroleum, amalahle, imigodi kunye nesinyithi, i-geology, impahla, ukwakhiwa, njl. icandelo lezoshishino.

3. Izilumkiso zokukhetha iimveliso ze-polyacrylamide:
① Ukukhethwa kweflocculant kuthathela ingqalelo ngokupheleleyo inkqubo kunye neemfuno zezixhobo.

②Amandla e-floc anokwandiswa ngokunyusa ubunzima be-molecular of flocculant.

③Ixabiso lentlawulo yeflocculant ihlolwe ngemifuniselo.

④Ukutshintsha kwemozulu (ubushushu) kuchaphazela ukhetho lweflocculant.

⑤Khetha ubunzima be-molecular of flocculant ngokobungakanani befloc obufunwa yinkqubo yonyango.

⑥ Hlanganisa i-flocculant kunye ne-sludge kakuhle phambi konyango.
4. Iimpawu zokusebenza:

1. Imolekyuli ye-polyacrylamide inemfuza eyakhayo, isakhono esinamandla se-flocculation, idosi ephantsi, kunye nesiphumo sonyango esicacileyo.

2. Ine-solubility efanelekileyo kunye nomsebenzi ophezulu. Iintyatyambo ze-alum ezenziwe ngu-condensation kumzimba wamanzi zinkulu kwaye zihlala ngokukhawuleza. Inomthamo wokucoca amaxesha angama-2-3 amakhulu kunezinye iipolima ezinyibilikayo emanzini.

3. Ukulungelelanisa okunamandla kunye nempembelelo encinci kwixabiso le-pH kunye nobushushu bomzimba wamanzi. Emva kokucocwa kwamanzi akrwada, afikelela kumgangatho wesizwe wesalathiso samanzi. Emva kokunyanga, iinqununu ezimisiweyo emanzini zifezekisa injongo ye-flocculation kunye nokucaciswa, okuhambelana nokulungiswa kwe-ion exchange kunye nokulungiswa kwamanzi ahlambulukileyo.

4. I-corrosion encinci kwaye kulula ukuyisebenzisa, enokuphucula ukuqina kwabasebenzi kunye neemeko zokusebenza zenkqubo ye-dosing.

5. Umda wokusetyenziswa kwepolyacrylamide

I-molecule ye-polyacrylamide ine-genesis enhle (-CONH2), enokuthi i-adsorb kwaye ibhulorho amasuntswana amisiweyo ahlakazwe kwisisombululo. Inefuthe elinamandla le-flocculation. Iyakwazi ukukhawuleza ukuhlaliswa kweengqungquthela ekumisweni, kwaye inokukhawuleza okucacileyo kwesisombululo. Iyakwazi ukucacisa nokukhuthaza ukuhluzwa, ngoko ke isetyenziswa ngokubanzi kunyango lwamanzi, amandla ombane, imigodi, ukulungiswa kwamalahle, iimveliso ze-asbestos, imboni ye-petrochemical, i-papermaking, i-textile, i-sugar refining, iyeza, ukukhuselwa kwendalo, njl.
1. Njenge-flocculant, isetyenziswa kakhulu kwiinkqubo zokwahlula i-industrial solid-liquid, kubandakanywa i-sedimentation, i-clarification, i-concentration kunye ne-sludge dehydration. Amashishini aphambili asetyenziswayo ngala: ukucocwa kwamanzi amdaka edolophini, ishishini lamaphepha, ishishini lokulungisa ukutya, ishishini lepetrochemical, Ukucocwa kwamanzi amdaka kwishishini lesinyithi, ishishini lokulungisa izimbiwa, ishishini lokudaya, ishishini leswekile kunye namashishini ahlukeneyo. Isetyenziselwa ukunyibilika kodaka kunye nokuphelelwa amanzi ngodaka kunyango logutyulo lwasezidolophini kunye nenyama, iinkukhu, kunye nokulungiswa kokutya kwamanzi amdaka. Amaqela ahlawulwe ngokufanelekileyo aqulethe umbane anciphise i-colloids ye-organic charged engalunganga kwi-sludge kunye nomsebenzi wokudibanisa kunye nokudibanisa kweepolymers zikhuthaza iinqununu ze-colloidal ukuba zidibanise kwiiflocs ezinkulu kwaye zihluke ekumisweni kwazo. Isiphumo sicacile kwaye idosi encinci.
2. Kwishishini lephepha, linokusetyenziswa njengephepha elomileyo lamandla, uncedo lokugcina kunye noncedo lokucoca, olunokuphucula umgangatho wephepha, ukugcina iindleko kunye nokwandisa amandla okuvelisa amaphepha. Inokwenza ngokuthe ngqo iibhulorho ze-electrostatic kunye ne-ion zetyuwa ye-inorganic, iifayibha kunye nezinye iipolymers eziphilayo ukunyusa amandla omzimba wephepha, ukunciphisa ilahleko yeefiber okanye izihluzi, ukukhawulezisa ukuhluzwa kwamanzi, kunye nokudlala indima yokomeleza, ukugcinwa kunye noncedo lokucoca. Ingasetyenziselwa unyango lwamanzi aMhlophe, kwangaxeshanye, inokuba nefuthe elicacileyo le-flocculation ngexesha lenkqubo ye-deinking.
3. I-Fiber slurry (imveliso ye-asbestos-samente) inokuphucula ukukhutshwa kwezinto ezenziwe nge-asbestos-cement kunye nokwandisa amandla ebhodi ye-asbestos engenanto; kwiibhodi ze-insulation, inokuphucula amandla okubophelela kwezongezo kunye nemicu.
4. Ingasetyenziswa njengesicacisi kumanzi amdaka asemgodini kunye namanzi amdaka okuhlamba amalahle kwimizi-mveliso yemigodi neyokulungisa amalahle.
5. Ingasetyenziselwa ukunyanga ukudaya amanzi amdaka, amanzi amdaka esikhumba, kunye namanzi amdaka aneoyile ukususa ubumdaka kunye nokuguqula umbala ukufezekisa imigangatho yokukhupha.
6. Ekuhlanjululeni i-phosphoric acid, inceda ukwahlula i-gypsum kwinkqubo emanzi ye-phosphoric acid.
7. Isetyenziswa njengeflocculant yokucoca amanzi kwizityalo zamanzi ezinomthombo wamanzi omlambo.
6. Iindlela zokusetyenziswa kunye nezilumkiso:
1. Sebenzisa amanzi angathathi hlangothi, angenatyuwa ukuze ulungiselele isisombululo se-aqueous kunye ne-concentration ye-0.2%.
2. Ekubeni le mveliso ifanelekile kuluhlu olubanzi lwamaxabiso e-pH yamanzi, i-dosage jikelele yi-0.1-10ppm (0.1-10mg / L).
3. Inyibilike ngokupheleleyo. Xa unyibilika, gxobhoza amanzi ngokucokisekileyo uze wongeze umgubo weyeza ngokucothayo nangokulinganayo ukuthintela ukuvaleka kwemibhobho kunye neempompo ezibangelwa kukushukuma okukhulu kunye namehlo entlanzi.
4. Isantya sokuxuba ngokuqhelekileyo si-200 rpm kwaye ixesha alikho ngaphantsi kwemizuzu engama-60. Ukunyusa ngokufanelekileyo ubushushu bamanzi ngama-20-30 degrees Celsius kunokukhawulezisa ukunyibilika. Ubushushu obukhulu beyeza elimanzi kufuneka libe ngaphantsi kwama-60 degrees.
5. Qinisekisa idosi efanelekileyo. Qinisekisa idosi efanelekileyo ngokusebenzisa imifuniselo phambi kokusetyenziswa. Ngenxa yokuba i-dosage iphantsi kakhulu, ayiyi kusebenza, kwaye ukuba i-dosage iphezulu kakhulu, iya kuba nefuthe elichaseneyo. Xa idlula i-concentration ethile, i-PAM ayigcini nje ukujikeleza, kodwa iyahlakazeka kwaye isetyenziswe ngokuzinzileyo.
6. Le mveliso kufuneka igcinwe kwindawo epholileyo, eyomileyo ukukhusela umswakama.
7. Indawo ekusetyenzwa kuyo kufuneka igungxulwe ngamanzi rhoqo ukuyigcina icocekile. Ngenxa ye-viscosity yayo ephezulu, i-PAM esasazeke phantsi komhlaba iba mpuluswa xa ifakwe emanzini, ikhusela abaqhubi ukuba bangatyibiliki kwaye babangele iingozi zokhuseleko.
8. Le mveliso ifakwe kwiingxowa zeplastiki kwaye umaleko wangaphandle wenziwe ngeeplastiki eziphothiweyo eziphothiweyo, ingxowa nganye yi-25Kg.
7. Iimpawu zomzimba kunye neempawu zokusetyenziswa
1. Iimpawu ezibonakalayo: I-molecular formula (CH2CHCONH2) r
I-PAM yipolymer yomgca. Inyibilika lula emanzini kwaye iphantse inganyibiliki kwibenzene, ethylbenzene, esters, acetone kunye nezinye izinyibilikisi eziqhelekileyo zendalo. Isisombululo sayo esinamanzi silulwelo oluphantse lubonakale elubala kwaye luyimveliso engeyongozi. I-PAM engabonakaliyo, eqinile i-hygroscopic, kwaye i-hygroscopicity iyanda ngokunyuka kwe-ionicity. I-PAM inozinzo oluhle lwe-thermal; inozinzo olululo xa ishushu kwi 100°C, kodwa ibola lula ukuvelisa igesi yenitrogen xa ifudunyezwa kwi 150°C okanye ngaphezulu. Ingena kwi-midization kwaye ayinyibiliki emanzini. Ubuninzi (g) ml 23 ° C 1.302. Ubushushu bokutshintsha kweglasi yi-153°C. I-PAM ibonisa ukungabikho kwe-Newtonian fluidity phantsi koxinzelelo.
2. Iimpawu zokusetyenziswa
I-Flocculation: I-PAM inokunciphisa izinto ezimisiweyo ngombane, i-adsorption yebhulorho, kwaye yenze i-flocculation.
Ukubambelela: Inokuthi isebenze njenge-adhesive ngokusebenzisa i-mechanical, physical and chemical effects.
Ukunciphisa ukuchasana: I-PAM inokunciphisa ngokufanelekileyo ukuxhatshazwa kwe-frictional fluids. Ukongeza inani elincinci le-PAM kumanzi kunokunciphisa ukuxhatshazwa kwe-friction nge-50-80%.
Ukuqina: I-PAM inefuthe lokuqina phantsi kweemeko zombini ezingathathi hlangothi kunye ne-acidic. Xa ixabiso le-pH lingaphezulu kwe-10 ° C, i-PAM i-hydrolyzed ngokulula kwaye inesakhiwo se-semi-reticular, kwaye ukuqina kuya kubonakala ngakumbi.
8. Ukwenziwa kunye nenkqubo ye-polyacrylamide PAM
9. Amanyathelo okupakisha kunye nokugcina:
Kule mveliso, qiniseka ukuba uyayikhusela kumswakama, imvula, kunye nokukhanya kwelanga.
Ixesha lokugcinwa: iminyaka emi-2, ingxowa yephepha eyi-25kg (ingxowa yeplastiki efakwe kwingxowa yephepha ye-kraft ngaphandle).
