Xim pos huab coagulant
Tej Dej Num Tswv Yim
Cov xim dej pleev xim yog qhov nyuaj cais tawm ntawm cov dej vim nws qhov tsis haum nrog dej, thiab nws ua npuas ntau, uas cuam tshuam rau kev tsim khoom. Dej-xim pleev xim yuam kev coagulant yog ib hom tshuaj lom neeg ua raw khoom tshwj xeeb siv rau kev kho cov dej-xim xim pov tseg dej thiab tshem cov xim (xim slag) hauv cov dej mus ncig. Dej-xim pleev xim yuam kev coagulant yog ib hom kev sib ntxiv rau kev kho tshuaj tsuag ntawm cov dej ncig hauv kev lag luam xim. Lub luag haujlwm tseem ceeb yog tshem tawm qhov viscosity ntawm cov xim pleev xim, ua kom pom kev pleev xim rau hauv floc thiab ntab nws saum nplaim dej, uas yog yooj yim khaws thiab tshem tawm (lossis cia li tswj lub slag tshem tawm).

1. Rho thiab tshem tawm lub viscosity ntawm cov xim poob rau hauv cov dej mus ncig ntawm ntau hom dej thaiv qhov dej thaiv lub tsev thaiv dej. |
2. Quav thiab txhuam cov xim seem |
|
3. Tswj microbial kev ua ntawm circulating dej thiab tswj cov dej kom zoo |
4. Txhim kho txoj kev pab lub neej ntawm kev xa dej, txo tus nqi tu lub thawv thiab dej |
|
5. Txhim kho cov khoom siv dej khib nyiab pov tseg muaj peev xwm thiab txo tus nqi dej khib nyiab |
6. Xim slag tsis yog nplaum thiab ntxhiab, yooj yim kom lub cev qhuav dej thiab txo tus nqi ntawm cov ntawv ua slag |
|
7. Kev tswj cov khoom siv thiab cov ntsuas tso tawm kom zoo, txhim kho kev tsim khoom, kom ntseeg tau cov khoom zoo, thiab txo tus nqi tsim khoom |
8. Chav xim txau yog yooj yim los ntxuav thiab tswj, nce kev pab lub neej thiab txo nqi hloov khoom siv |
|
9. Txhim kho qhov chaw ua haujlwm ntawm cov txau khoom thiab cov haujlwm ua haujlwm |

Cov Lus Qhia Saib Xyuas
Cov xim lim dej ua kom yuam kev coagulant tau muab faib ua tus neeg sawv cev A thiab tus neeg sawv cev B. Ob tus neeg sawv cev tau siv ua ke (feem ntau ntawm cov kab mob ntawm cov neeg sawv cev A thiab B yog 3: 1-2). Ua ntej tshaj ntxiv qee qhov nqi ntawm tus neeg saib xyuas A (feem ntau 2 ‰ ntawm tus nqi ntawm cov xim pleev xim dej) hauv cov xim muaj pa mus rau hauv dej. Tus neeg saib xyuas A tau ntxiv rau ntawm qhov nkag ntawm qhov dej xa mus, thiab tus neeg sawv cev B ntxiv rau ntawm qhov hluav taws xob uas yog dej mus rau kev pleev xim (tus neeg sawv cev A thiab B yuav tsum tsis txhob ntxiv rau tib qho chaw tib lub sijhawm). Feem ntau, qhov ntau npaum li cas ntawm tus neeg sawv cev yog 10-15% ntawm tus nqi ntawm overspray. Feem ntau, tus neeg sawv cev tuaj yeem txuas khoom ntxiv los yog txiav txim siab los ntawm lub tshuab nqus pa metering. Raws li cov nyiaj ntawm overspray, cov ndlwg ntws thiab hloov chaw ntawm lub tshuab nqus pa muaj peev xwm kho tau.
| specification | tsos | Qhov ceev (20 ° C) | PH (10g / L) | Qhov ntsuas phom sij (20 ° C) |
| Tus neeg sawv cev | kua-zoo li kua | 1,08 ± 0.02 | 7 ± 0.5 | 1.336 ± 0.005 |
| B- tus neeg sawv cev | Cov kua ua kua | 1,03 ± 0.02 | 6 ± 0.5 | 1.336 ± 0.005 |
Cov Lus Qhia
1. Nws raug nquahu kom ntxuav lub tank tag nrho thiab hloov dej ib zaug ua ntej siv tus neeg sawv cev, kom cov nyhuv yuav zoo dua. Tom qab hloov cov dej, thawj zaug kho cov dej huv nrog sodium hydroxide kom tswj tau 8-10PH tus nqi ntau, thiab ntxiv 1.5-2.0 kg ib tuj dej nyob ib puag ncig sodium hydroxide.
2. Ntxiv cov xim pleev xim av flocculant A kom qhov dej khov dej hloov mus los ntawm cov tshuaj tsuag lub rooj muag khoom txhua tag kis sawv ntxov tom qab dej hloov pauv (piv txwv li, lub rooj zaum tsuag dej tsuag twj lub cav); tom qab ntxiv cov tshuaj, tsim khoom thiab tshuaj tsuag xim li qub, thiab ntxiv cov xim pleev xim flocculant B ua ntej ua haujlwm. Cov xim muaj hlau feem ntau yog khaws cia (uas yog, lub poly xim pleev xim); cov xim tom qab uas raug tshem tawm tuaj yeem khaws cia tom qab ua haujlwm.
3. Qhov ntsuas qhov sib piv: qhov sib piv ntawm cov xim pleev xim thiab tshem tawm tus neeg sawv cev yog 1: 1, thiab txhua zaus cov xim pleev xim rau hauv cov dej mus ncig ntawm lub rooj zaum tsuag mus txog 20-25 kg, ntxiv 1 kg txhua. (Qhov sib piv no yog tus nqi kwv yees ua ntej. Qhov yuav tsum tau siv ntau npaum li cas yuav tsum tau kho me ntsis raws li hom xim thiab viscosity ntawm qhov chaw. Vim tias cov xim qub xim adsorbed nyob rau hauv cov tshuaj tsuag chav kav dej yuav haus ib feem ntawm cov potion, yog li tus nqi kev siv yeeb tshuaj thaum pib lub sijhawm noj tshuaj yuav tsum yog me ntsis. Loj heev)
4. Tsis tas yuav tau hloov kho tus nqi PH.
Kev nqa khoom thiab chaw cia khoom
1. Tsis txhob nchuav cov kua rau hauv lub qhov muag. Yog tias tiv tauj nrog cov kua, tam sim ntawd yaug qhov chaw hu nrog dej kom ntau.
2. Khaws cov xim flocculant AB nyob rau qhov chaw txias thiab zam rau lub hnub ncaj qha.
3. Tsis tuaj yeem muab khaws cia rau hauv alloys ntawm txhuas, hlau thiab tooj.
