Ngokumenyezelwa kanye nokuqaliswa kwemithetho kazwelonke yezemvelo eqina kakhulu, izidingo zokwakhiwa komdwebo wezimoto ziya ngokuya ziba phezulu.Ukudweba akufanele kuqinisekise kuphela ukusebenza okuhle kokunqanda ukugqwala, ukusebenza kokuhlobisa okuphezulu, nokusebenza okuphezulu kokwakhiwa, kodwa futhi kwamukele izinto zokwakha nezinqubo ngokusebenza kahle futhi kunciphise ukukhishwa kwenhlanganisela ye-organic eshintshashintshayo (VOC).Opende abasekelwe emanzini kancane kancane baba insikaezinengilazingenxa yezingxenye zabo ezithinta imvelo.
Amapende asekelwe emanzini awakwazi nje ukuthuthukisa ngokuphumelelayo ukusebenza kahle kokugcinwa, kodwa futhi abe nekhono eliqinile lokumboza, elinganciphisa inani lezendlalelo zokufafaza kanye nenani lopende osetshenzisiwe, futhi linganciphisa isikhathi sokufafaza nezindleko zokufafaza.
Umehluko phakathi kukapende osuselwe emanzini nowoyela
1. I-diluting agents ehlukene
I-ejenti ehlanjululwayo yopende olusekelwe emanzini ngamanzi, okufanele afakwe ngezilinganiso ezahlukene ukusuka ku-0 kuya ku-100% kuye ngesidingo, futhi i-ejenti yokuhlanjululwa kapende osekelwe kumafutha iyi-solvent ephilayo.
2. Ukusebenza kwemvelo okuhlukile
Amanzi, into ehlanjululwayo kapende osuselwe emanzini, awaqukethe i-benzene, i-toluene, i-xylene, i-formaldehyde, izinsimbi ezisindayo ze-TDI ezinobuthi kanye nezinye izinto eziyingozi ze-carcinogenic, ngakho-ke aphephile empilweni yomuntu.
Amanzi kabhanana, i-xylene namanye amakhemikhali avame ukusetshenziswa njenge-ejenti yokuhlambulula upende osuselwe kuwoyela, oqukethe inani elikhulu le-benzene namanye amakhemikhali ayingozi.
3. Imisebenzi ehlukene
Upende osuselwe emanziniakugcini nje ngokungcolisa imvelo, kodwa futhi inefilimu kapende ecebile, ecwebezelayo ngemva kokusebenza phezu kwento futhi inokuguquguquka okuhle kakhulu nokumelana namanzi, ukuhuzuka, ukuguga nokuphuzi.
Izici zobuchwepheshe zokufafaza ngopende osuselwe emanzini
Ukushibilika kwamanzi kupende osuselwe emanzini kulawulwa ngokuyinhloko ngokulungisa izinga lokushisa kanye nomswakama wegumbi lokufafaza, okuqinile okunamathelayo kuvame ukuba ngu-20% -30%, kuyilapho okuqinile okunamathelayo kapende osuselwe kuncibilikidi kuphezulu ngokufinyelela ku-60% -70%, ngakho-ke ukushelela kopende olusekelwe emanzini kungcono.Kodwa-ke, idinga ukushiswa futhi yomiswe nge-flash, ngaphandle kwalokho kulula ukuba nezinkinga zekhwalithi njengokulenga namabhamuza.
1. Izici zobuchwepheshe zemishini
Okokuqala, ukugqwala kwamanzi kukhulu kunezincibilikisi, ngakho uhlelo lokuhlanza amanzi olujikelezayo lwegumbi lokufafaza ludinga ukwenziwa ngensimbi engagqwali;okwesibili, isimo sokugeleza komoya segumbi lokufafaza kufanele sibe sihle, futhi isivinini somoya kufanele silawulwe phakathi kuka-0.2 ~ 0.6m/s.
Noma umthamo wokugeleza komoya ufinyelela ku-28,000m3/h, ongahlangatshezwana nawo ekamelweni elivamile lokupenda lokubhaka.Futhi igumbi lokumisa ngenxa yomswakama ophezulu emoyeni lizophinde libangele ukugqwala kwemishini, ngakho-ke udonga lwegumbi lokumisa ludinga ukwenziwa ngezinto zokulwa nokubola.
2. Automatic spray enamathela uhlelo
Izinga lokushisa elilungile legumbi lokufafaza lokufafaza ngopende osuselwa emanzini ngu-20 ~ 26 ℃, futhi umswakama ofanele wesihlobo ngu-60 ~ 75%.Izinga lokushisa elivumelekile ngu-20 ~ 32 ℃, futhi umswakama ovumelekile ohlobene ngu-50 ~ 80%.
Ngakho-ke, kufanele kube nezisetshenziswa ezifanele zokulawula izinga lokushisa kanye nomswakama ekamelweni lokufafaza.Izinga lokushisa nomswakama kungalawulwa ekamelweni lokufafaza lokupenda okuzenzakalelayo kwasekhaya ebusika, kodwa izinga lokushisa noma umswakama awukwazi ukulawulwa ehlobo, ngoba umthamo wokupholisa mkhulu kakhulu ehlobo.
Ezindaweni ezishisa kakhulu nezinomswakama ophezulu, kufanele ufake i-air conditioner emaphakathi ekamelweni lokufafaza ngaphambi kokusebenzisa amanziezinengilazi, futhi umoya obandayo kufanele ulethwe ehlobo ukuze kuqinisekiswe izinga lokwakha likapende osekelwe emanzini.
3. Eminye imishini
(1) Isibhamu sikapende esisekelwe emanzini
Ngokuvamile, izibhamu zokufafaza ngopende ezisekelwe emanzini ezinevolumu ephezulu kanye nobuchwepheshe bokucindezela okuphansi (HVLP) zisetshenziswa.Esinye sezici ze-HVLP umthamo womoya ophezulu, ovame ukuba ngu-430 L/min, ngakho-ke isivinini sokumisa sopende osekelwe emanzini singandiswa.
Izibhamu ze-HVLP ezinevolumu ephezulu yomoya kodwa i-atomization ephansi (15μm), uma isetshenziswa esimweni sezulu esomile, zizokoma ngokushesha futhi zenze upende osuselwe emanzini ugeleze kabi.Ngakho-ke, kuphela isibhamu esinengcindezi ephakathi nendawo esine-atomization ephezulu (1μpm) esizonikeza umphumela ongcono kakhulu.
Eqinisweni, isivinini sokumisa upende osekelwe emanzini akusho lutho kubanikazi bezimoto, futhi abangakubona ukulinganisa, ukucwebezela nombala kapende.Ngakho-ke, lapho ufutha upende olusekelwe emanzini, akufanele nje ufune isivinini, kodwa kufanele unake kakhulu ukusebenza okuphelele kopende olusekelwe emanzini, ukuze wanelise umnikazi wemoto.
(2) Isibhamu esiphehla ngopende esisekelwe emanzini
Abanye abafutha banomuzwa wokuthi upende osuselwe emanzini uyashesha ukoma uma uqhathaniswa nopende osekelwe ku-solvent, ikakhulukazi ehlobo.Lokhu kungenxa yokuthi opende abasuselwe kuncibilikisi bayahwamuka ngokushesha futhi bome kalula ehlobo, kuyilapho besekelwe emanziniezinengilaziazizweli kangako izinga lokushisa.Isilinganiso sesikhathi sokumisa i-flash sopende osuselwe emanzini (imizuzu emi-5-8) empeleni sincane kuneso sikapende osuselwe kuncibilikisiwe.
I-blow gun ibalulekile impela, okuyithuluzi lokomisa upende osuselwe emanzini mathupha ngemva kokuba usufuthwe.Iningi lezibhamu ezivamile zokupenda ezisekelwe emanzini emakethe namuhla zandisa umthamo womoya ngomphumela we-venturi.
(3) Imishini yokuhlunga umoya ecindezelwe
Umoya ocindezelwe ongahlungiwe uqukethe uwoyela, amanzi, uthuli nokunye ukungcola, okuyingozi kakhulu ekusebenzeni kokufafaza upende osekelwe emanzini futhi kungabangela ukukhubazeka okuhlukahlukene kwekhwalithi kumafilimu opende, kanye nokuguquguquka okungenzeka kokucindezela komoya okucindezelwe kanye nevolumu.Ukusebenza kabusha ngenxa yezinkinga zekhwalithi yomoya ecindezelwe akukhulisi nje kuphela izindleko zabasebenzi nezokusebenza, kodwa futhi kuvimbela eminye imisebenzi.
Izinyathelo zokuphepha zokwakha amapende asekelwe emanzini
1. I-solvent encane ye-organic ivumela upende osuselwe emanzini ukuthi ungaphenduli ne-substrate, futhi amanzi ayo e-ejenti ehlanjululwayo andisa isikhathi esomile se-flash.Ukufafaza kwamanzi kubangela ukuthi amanzi ehle kalula ezindaweni eziwugqinsi kakhulu, ngakho-ke akufanele ufutha ajiye kakhulu okokuqala ngqa!
2. Isilinganiso sikapende osuselwe emanzini ngu-10: 1, futhi kuphela i-10g ye-ejenti yokuhlanjululwa emanzini yengezwe ku-100g wopende osuselwe emanzini ungaqinisekisa ukumbozwa okuqinile kopende olusekelwe emanzini!
3. Uwoyela kufanele ususwe nge-degreaser esekelwe uwoyela ngaphambi kokufafaza umdwebo, futhi umshini wokukhipha amanzi kufanele usetshenziselwe ukusula nokufutha, okubaluleke kakhulu, ngoba kunganciphisa kakhulu amathuba okuba nezinkinga!
4. Ifunnel ekhethekile kanye nendwangu yothuli ekhethekile kufanele isetshenziselwe ukuhlunga okusekelwe emanziniezinengilazi.
