Marasha ekugeza chirimwa chepolyacrylamide imhando yepolymer. Inogona kunyatso kujekesa mvura yekugeza marasha, kuita kuti zvimedu zvakanaka mumvura yekugeza marasha zvikurumidze kuungana uye kugadzirisa, uye kuwedzera kudzoreredza huwandu hwepeat, nekudaro kuwana mhedzisiro yekuchengetedza mvura, kudzivirira kusvibiswa, uye kuwedzera kuvandudza kushanda kwekambani.
1. Polyacrylamide chigadzirwa sumo:
Polyacrylamide yakakosha mvura-inonyungudika polima uye ine zvakakosha zvimiro zvakaita sekupuruzira, kukora, kugerwa kweshear, kuderedza kudhonza, uye kupararira. Zvinhu izvi zvinosiyana zvichienderana neiyo inotorwa kubva. Naizvozvo, inoshandiswa zvakanyanya mukutora mafuta, kugadzira zvicherwa, kuwacha marasha, simbi, indasitiri yemakemikari, kugadzira mapepa, machira, kuchenesa shuga, mushonga, kuchengetedza kwezvakatipoteredza, zvekuvakisa, kugadzirwa kwekurima nemamwe madhipatimendi.
piri. Chigadzirwa chemuviri uye chemakemikari zviratidzo:
Kuonekwa: chena kana zvishoma yero zvimedu, zvinobudirira zvemukati ≥98%, molecular uremu 800-14 miriyoni zvikamu.
tatu. Kuita kwechigadzirwa:
1. Shandisa chigadzirwa ichi kuti uwane yakasarudzika flocculation mhedzisiro ine diki dosage.
2. Nguva yekuita pakati pechigadzirwa ichi nemvura yemarasha ipfupi uye kukurumidza kwekuita kunokurumidza. compact.
3. Ichi chigadzirwa chinogona kushandiswa kwemarasha slurry kugadzirisa, tailings kugadzirisa, tailings centrifugal separation, nezvimwewo.
Four. Dosage:
Kuyerwa kwechigadzirwa ichi kunoenderana nemhando yemarasha, mhando yemvura uye marasha ekushambidzika kwemazimbe emvura mumudziyo wekugadzira marasha.
shanu. Nzira yekushandisa:
1. Dissolve: Shandisa midziyo isina-ferrous. Shandisa mvura yakachena ine tembiricha yemvura iri pasi pe60°C. Zvishoma nezvishoma uye zvakaenzana kuparadzira marasha ekugeza flocculant mumudziyo paunenge uchidhonza mvura, kuitira kuti marasha ekugezesa flocculant izere nemvura mumudziyo. Mushure mekusimudzira kuenderera kwemaminetsi 50-60, inogona kushandiswa. Kurudzira mutsara weshizha Kumhanya kunoenderana nemudziyo.
2. Kuwedzera: Dilute iyo yakanyungudika yekugeza marasha flocculant nemvura yakachena uye shandisa iyo yekuisa pakati pe0.02-0.2%. Shandisa vharuvhu kuti udzore kuyerera uye zvakaenzana uwedzere kune marasha slime mvura. (Unogonawo kugadzirira zvakananga flocculant ine concentration pakati pe 0.02-0.2%.
6. Notes:
1. Kana isina kubatwa nemazvo panguva yekunyungudutswa, isinganyanyike yakamiswa flocculent inowoneka yakaturikwa mumvura. Inofanirwa kusefa kunze kana zvishoma nezvishoma kumirira kuparadzwa isati yashandiswa, pasina kukanganisa mashandisiro ekushandisa.
2. Mari yekuwedzera inofanira kuva pakati nepakati. Zvakawanda kana zvishoma hazvizogone kuita zviri pachena flocculation effect. Mushandisi anofanirwa kugadzirisa dosage zvinoenderana nemamiriro akasiyana senge marasha slime mvura yemhando, kumhanya kwemvura yekuyerera uye huwandu hwekugeza.
3. Kana chiyero che flocculant chiri chiduku uye chigumisiro chacho hachina kunaka panguva yekushandiswa, asi kana dheji ichiwedzerwa, tambo uye mamwe matambudziko ekugara achaitika. Iwe unogona kuderedza kana kuwedzera kuwanda kweiyo flocculant mhinduro uye kuwedzera kuyerera kweyero kuti uwedzere dosage ye flocculant. Kana kufambisa iyo flocculant yekuwedzera chinzvimbo kumashure kuti irebe nguva yekusanganisa yemvura inoyerera uye yemarasha slime mvura inogonawo kugadzirisa dambudziko rataurwa pamusoro apa.
