Ipeyinti inkungu egudileyo
Umsebenzi oSebenzayo
Ipeyinti esekwe emanzini kunzima ukwahlula emanzini ngenxa yokungahambelani kwayo namanzi, kwaye ivelisa amagwebu amaninzi, achaphazela imveliso. I-paint-based coagulant ye-water-coagulant luhlobo lwe-arhente yemichiza ekrwada esetyenziselwa ukujongana nonyango lwamanzi amdaka okupeyinta amanzi kunye nokususwa kwepeyinti (ipeyinti ye-slag) ekujikelezeni amanzi. I-coagulant eyenziwe ngepeyinti esemanzi sisongezo esiqhelekileyo kunyango lokutshiza lokujikeleza kwamanzi kushishino lwepeyinti. Umsebenzi ophambili kukususa i-viscosity yenkungu yepeyinti, ukudibanisa inkungu yepeyinti kwi-floc kwaye uyijikeleze ngaphezulu kwamanzi ajikelezayo, ekulula ukuwasindisa kunye nokususa (okanye ukulawula ngokuzenzekelayo ukususwa kwe-slag).

1. Ukubola kunye nokususa i-viscosity yepeyinti ewayo emanzini ajikelezayo eentlobo ezininzi zamadokodo okutshiza amanzi |
2.Qinisa kwaye unqumamise intsalela yepeyinti |
|
3.Ukulawula imisebenzi yeentsholongwane yokujikeleza kwamanzi kunye nokugcina umgangatho wamanzi |
4. Ukuphucula ubomi benkonzo yokujikeleza kwamanzi, ukunciphisa iindleko zetanki lokucoca kunye namanzi |
|
5. Ukuphucula umthamo wonyango lwamanzi amdaka kunye nokunciphisa iindleko zokucoca amanzi amdaka |
6. Ipeyinti ye-slag ayinamatheli kwaye ayinasongo, kulula ukuba iphelise kwaye inciphise indleko ze-slag ezilahliweyo |
|
7. Gcina ulungelelwaniso kunye nokukhutshwa kwemali, ukuphucula ukusebenza kwemveliso, ukuqinisekisa umgangatho wemveliso, kunye nokunciphisa iindleko zemveliso |
8. Ipeyinti igumbi lokutshiza kulula ukulicoca kunye nokuligcina, ukwandisa ubomi benkonzo kunye nokunciphisa iindleko zokubuyisela izixhobo |
|
9. Ukuphucula imeko yokusebenza kwendawo yokutshiza nokusebenza ngokukuko |

Imiyalelo Isishwankathelo
I-coagulant esekwe emanzini eyakhelwe amanzi yahlulwe yarhente A kunye nearhente B. Ezi arhente zimbini zisetyenziswa kunye (ngokubanzi umlinganiselo weearhente A no-B ngu-3: 1-2). Kuqala yongeza isixa esithile searhente A (ngokubanzi yi-2 ‰ yemali yepeyinti ejikeleza amanzi) kwipeyinti ejikeleza amanzi. Ummeli A wongezwa kwindawo yokungena yamanzi ajikelezayo, kwaye iarhente B yongezwa kwindawo yokuphuma yokuhambisa amanzi (iiarhente A kunye no-B akufuneki zongezwe kwindawo enye ngaxeshanye). Ngokubanzi, idosi yearhente yi-10-15% yexabiso lokudlula ngaphezulu. Ngokwesiqhelo, iarhente inokongezwa ngesandla okanye ngokuzenzekelayo yimpompo yokulinganisa. Ngokwenani le-overspray, inqanaba lokuhamba kunye nokushenxiswa kwempompo yemitha kunokulungiswa.
| imigaqo | imbonakalo | Ukuxinana (20 ° C) | PH (10g / L) | Isalathiso sokutsala (20 ° C) |
| Ummeli | ncamathisela ulwelo | I-1.08 ± 0.02 | 7 ± 0.5 | 1.336 ± 0.005 |
| B- arhente | Ulwelo viscous | 1.03 ± 0.02 | 6 ± 0.5 | 1.336 ± 0.005 |
Imiyalelo
1. Kucetyiswa ukuba ucoce itanki ngokupheleleyo kwaye utshintshe amanzi kube kanye ngaphambi kokusebenzisa iarhente, ukuze isiphumo sibe ngcono. Emva kokutshintsha amanzi, qala uhlengahlengise umgangatho wamanzi ngesodiyam hayidroksayidi yokulawula uluhlu lwexabiso le-8-10PH, kwaye ungeze i-1.5-2.0 kg ngetoni nganye yamanzi Kujikeleze isodiyam hayidroksayidi.
2. Yongeza inkungu epeyintiweyo ekujikelezisweni kwamanzi kwindawo yokutshiza rhoqo kusasa emva kotshintsho lwamanzi (okt, imoto yokumpompa imoto); emva kokudibanisa iyeza, ukuvelisa kunye nokupeyinta njengesiqhelo, kwaye wongeze inkungu epeyintwayo flocculant B ngaphambi komsebenzi. Intsalela yepeyinti ihlala ihlangulwa (Oko kukuthi, itanki yepeyinti); intsalela yepeyinti enqunyanyisiweyo inokuhlangulwa emva komsebenzi.
3. Umlinganiselo we-Dosing: Umlinganiselo we-dosing of remover paint and agenting is 1: 1, kwaye ixesha ngalinye inani lepeyinti elitshiziweyo kumanzi ajikelezayo kwindawo yokutshiza lifikelela kwi-20-25 kg, yongeza i-1 kg nganye. (Lo mlinganiselo ulixabiso eliqikelelweyo kwangaphambili. Eyona idosi kufuneka ihlengahlengiswe kancinane ngohlobo lwepeyinti kunye ne-viscosity kwindawo leyo. Amachiza asetyenziswa kwixesha lokuqala lokuthatha idosi kufuneka abe mbalwa kakhulu.
4. Akukho sidingo sokuhlengahlengisa ixabiso le-PH.
Ukuphathwa nokugcinwa
1. Kuphephe ukutshiza ulwelo emehlweni. Ukuba unxibelelana nolwelo, kwangoko gungxula indawo yokudibana namanzi amaninzi.
2. Gcina i-paint flocculant AB kwindawo epholileyo kwaye uphephe ukukhanya kwelanga.
3. Ayinakugcinwa kwii-alloys ze-aluminium, isinyithi kunye nobhedu.
