Indlela yokusebenzisa iikhemikhali zokucoca amanzi 1

Ngoku sinikela ingqalelo engakumbi ekunyangweni kwamanzi amdaka xa ungcoliseko lokusingqongileyo lusiya lusiba mandundu. Iikhemikhali zonyango lwamanzi zizinto ezincedisayo ezifunekayo kwizixhobo zonyango lwamanzi amdaka. Ezi khemikhali zahlukile ngeziphumo kunye neendlela zokusebenzisa. Apha sichaza iindlela zokusebenzisa kwiikhemikhali ezahlukeneyo zonyango lwamanzi.

I. Indlela yokusebenzisa iPolyacrylamide: (Kwimizi-mveliso, impahla yelaphu, amanzi amdaka kamasipala njalo njalo)

1. Nyibilikisa imveliso njengesisombululo se-0.1%-0,3%. Kungcono ukusebenzisa amanzi angathathi cala angenatyuwa xa unyibilikisa. (Njengomanzi epompo)

2. Nceda uqaphele: Xa uxuba imveliso, nceda ulawule izinga lokuhamba komatshini wokulinganisa ozenzekelayo, ukuze uphephe ukuhlangana, imeko ye-fish-eye kunye nokuvaleka kwemibhobho.

3. Ukuxuba kufuneka kuthathe imizuzu engaphezu kwama-60 ngemiqulu engama-200-400/min. Kungcono ukulawula ubushushu bamanzi njenge-20-30 ℃, nto leyo eya kukhawulezisa ukunyibilika. Kodwa nceda uqinisekise ukuba ubushushu bungaphantsi kwama-60 ℃.

4. Ngenxa yobubanzi be-ph obunokuhlengahlengiswa yile mveliso, idosi ingaba yi-0.1-10 ppm, ingalungiswa ngokomgangatho wamanzi.

Indlela yokusebenzisa i-paint mist coagulant: (Iikhemikhali ezisetyenziselwa ngakumbi unyango lwelindle lepeyinti)

1. Kwinkqubo yokupeyinta, ngokuqhelekileyo yongeza i-paint mist coagulant A kusasa, uze ufefe ipeyinti ngokwesiqhelo. Ekugqibeleni, yongeza i-paint mist coagulant B isiqingatha seyure ngaphambi kokuba uphume emsebenzini.

2. Inqanaba lokulinganisa le-paint mist coagulant I-arhente ikwindawo yokungena kwamanzi ajikelezayo, kwaye inqanaba lokulinganisa le-arhente B likwindawo yokukhupha amanzi ajikelezayo.

3. Ngokwenani lepeyinti yokutshiza kunye nobungakanani bamanzi ajikelezayo, lungisa ubungakanani bepeyinti yokufutha i-A kunye ne-B ngexesha elifanelekileyo.

4. Ukulinganisa ixabiso le-PH lamanzi ajikelezayo rhoqo kabini ngemini ukuze lihlale liphakathi kwe-7.5-8.5, ukuze le arhente ibe nefuthe elihle.

5. Xa amanzi ajikelezayo esetyenziswa ixesha elithile, umbane ohambayo, ixabiso le-SS kunye nomxholo wezinto eziqinileyo ezixhonyiweyo zamanzi ajikelezayo ziya kudlula ixabiso elithile, nto leyo eya kwenza le arhente ibe nzima ukuyinyibilikisa emanzini ajikelezayo kwaye ngaloo ndlela ichaphazele impembelelo yale arhente. Kucetyiswa ukuba ucoce itanki yamanzi kwaye ufake amanzi ajikelezayo endaweni yawo ngaphambi kokusebenzisa. Ixesha lokutshintsha amanzi lihambelana nohlobo lwepeyinti, ubungakanani bepeyinti, imozulu kunye neemeko ezithile zezixhobo zokugquma, kwaye kufuneka zisetyenziswe ngokuhambelana neengcebiso zengcali ekwindawo.
