Amanzi Angcolile Asebenzisa Upende Osekelwe Emanzini: Imithombo, Ukwakheka kanye Nezimpawu Eziyinhloko
Isingeniso
Upende osekelwe emanzini (oqhutshwa ngamanzi) usube yindinganiso embonini kuzo zonke izinhlobo zokuqeda insimbi, izimoto, ifenisha, upende oluyi-coil kanye neminye imikhakha eminingi, eqhutshwa yimithethonqubo ye-VOC kanye nokuqinisa izidingo zemvelo. Ngokuyinhloko baqeda ukukhishwa kwe-solvent esigabeni sokusetshenziswa - kodwa bahambisa inkinga phansi. Amanzi angcolile akhiqizwa ukukhiqizwa kopende kanye nemisebenzi yokupenda ingenye yezindlela ezinzima kakhulu zezimboni ukwelapha: azinzile, axubile kakhulu, abola kabi futhi anombala ogqamile.
Ngaphambi kokuba kukhethwe noma yiliphi ikhemistri, amanzi angcolile ngokwawo kumele aqondwe. Lesi sihloko sichaza ukuthi amanzi angcolile apendiwe asekelwe emanzini avelaphi kanye nezici ezinhlanu ezichaza ukuziphatha kwawo ekwelapheni.
Amanzi Angcolile Asebenzisa Upende Avelaphi?
Amanzi angcolile asekelwe emanzini akhiqizwa ngezigaba ezimbili eziyinhloko zokukhiqiza. Ezitshalweni eziningi, imifudlana emibili ihlanganiswa ibe amanzi angcolile "aphelele" ngaphambi kokwelashwa.
1. Inqubo yokukhiqiza upende ngamanzi angcolile
Ngesikhathi sokukhiqizwa kopende, amanzi angcolile avela ekuhlanzweni kwemishini yokukhiqiza (ama-mixer, ama-reactor, imigqa yokugcwalisa) kanye nokuhlanza phansi kwe-workshop. Lawa manzi okugeza aqukethe ama-monomer angaphendulwanga, ama-dispersant, izinsiza zokwenza ifilimu kanye nezinye izingxenye zokwakheka ezingazange zisabele ngokugcwele noma ezingafakwanga emkhiqizweni wokugcina.
2. Ukusetshenziswa kokufaka upende emanzini angcolile (ngezansi komfula)
Ezitshalweni zokumboza, amanzi angcolile akhiqizwa lapho kufakwa amanzi ajikelezayo ebhodweni lokufafaza nalapho kuhlanzwa izibhamu zokufafaza. Lo mfudlana uqukethe inani elikhulu lopende olulungiselelwe ukusetshenziswa, izinto zokupholisa kanye nezinsiza zokuhlanza — empeleni, uhlobo oluncibilikisiwe lopende oqediwe uqobo.
3. Amanzi angcolile ahlanganisiwe
Uma izindlela zokukhiqiza nezokusebenzisa zixubene, umphumela uba amanzi angcolile asekelwe emanzini aphelele anekhwalithi ehlukahluka njalo ngokwezikhathi zokukhiqiza, imibala yopende kanye nokwakheka kwawo.
Izici Ezinhlanu Ezichazayo
1. Ukwakheka okuyinkimbinkimbi kanye nomthwalo wezinto eziphilayo oshintshashintsha kakhulu
Amanzi angcolile aqukethe izinhlobo eziningi zezinto eziphilayo — ama-resins, ama-monomers e-acrylic, ama-dispersants, ama-surfactants, ama-coalescing agents, ama-biocides kanye nemibala. Umthwalo wezinto eziphilayo uyashintshashintsha kakhulu phakathi komjikelezo wokukhiqiza kanye nomjikelezo wokuhlanza, okwenza kube nzima ukulinganisa amakhemikhali njalo.
2. Uhlelo oluzinzile kanye nezinga eliphezulu le-emulsification
Ama-surfactant afanayo, ama-dispersant kanye nezinsiza zokwakha ifilimu eziqinisa upende kungaliqinisa futhi emanzini. Amanzi angcolile akha i-emulsion ezinzile lapho izigaba ze-polymeric kanye ne-pigment zihlakazeka kahle. Yingakho ukuhlukaniswa okulula kwamandla adonsela phansi kungasebenzi, futhi kungani Ukususwa komuncu impi yokuqala yokwelashwa.
3. Ukubola okungekuhle kanye nokuvinjelwa okunamandla kwezinto eziphilayo
Izingxenye eziningi eziphilayo ziyamelana nokuhlaselwa kwezinto eziphilayo, kanti ezinye - ikakhulukazi ama-biocides, ama-curing agents kanye nama-monomers athile - ziyavimbela noma zinobuthi kuma-microorganisms. Isilinganiso se-BOD/COD ngokuvamile siphansi, okusho ukuthi uhlelo lwezinto eziphilayo alukwazi ukusetshenziswa njengokwelashwa okuyinhloko ngaphandle kokwelashwa ngamakhemikhali anamandla.
4. Ukuqina kombala okuphezulu kanye nosawoti oshintshashintshayo
Ama-pigment nama-dye anikeza umbala oqinile, oxhomeke ekwakhekeni kwawo — opinki, obomvu, onsomi, ompunga, omnyama nokuningi. Okuqukethwe kukasawoti kuyashintshashintsha ngokwemikhuba yokwakheka kanye nokuhlanza, okungaphazamisa I-Chemistry Yokujiya kanye nokwelashwa okungezansi.
5. I-pH ecishe ingathathi hlangothi kuya kwe-alkaline kancane
Ngokungafani nemifudlana eminingi yezimboni, amanzi angcolile asekelwe emanzini avame ukuba cishe angathathi hlangothi noma abe ne-alkaline kancane (pH 7–8). Lokhu kuhle ngomqondo owodwa: kusho ukuthi kudingeka i-asidi encane noma i-alkaline ukuze kubuyekezweKodwa ifasitela lokusebenza elingathathi hlangothi (pH 6–7) lapho i-coagulation kanye ne-flocculation chemistry isebenza kahle kakhulu.
Kungani Lezi Zici Zibalulekile
Zonke izici zivimbela isitimela sokwelashwa:
- ifuna Ukususwa komuncu isinyathelo (sokuqedwa) ngaphambi kwanoma yikuphi ukuhlukaniswa koketshezi oluqinile.
- kusho ukuthi ukwelashwa kwamakhemikhali ngaphambi kwesikhathi kumele kuthwale umthwalo oyinhloko, ngokwelashwa kwezinto eziphilayo okusetshenziselwa kuphela ukupholisha noma njengesigaba esingezansi esivikelwe ukwelashwa kwangaphambi kwesikhathi okuphumelelayo.
- kudinga i-chemistry yokususa imibala eqondiwe, hhayi nje ukuhlangana okuvamile.
- ivumela lonke isitimela samakhemikhali ukuthi sisebenze ngaphakathi kwefasitela elingathathi hlangothi elifanele ngezindleko ezincane zokulungisa i-pH.
Uma zihlanganiswa, zikhomba isitimela esifushane, sokwelapha ngokomzimba namakhemikhali esidinga amakhemikhali amaningi kunokuba kube yisitshalo esivamile sebhayoloji.
Isiphetho
Amanzi angcolile asekelwe emanzini akhiqizwa kuzo zombili izigaba zokukhiqiza kanye nokusetshenziswa, futhi izici zawo ezichazayo — ukwakheka okuyinkimbinkimbi, ukuhlanganiswa okuzinzile, ukubola okungekuhle, umbala ophezulu kanye ne-pH ecishe ingathathi hlangothi — kunquma zonke izinqumo zokwelashwa ezilandelayo. Ukuqonda lezi zisekelo kuyisinyathelo sokuqala esibheke ohlelweni lokwelapha olufushane, olusheshayo noluzinzile.
