Iyiphi i-airbrush engcono kune-HVLP noma i-LVLP: umehluko nokuqhathaniswa kwezimpawu
Okuqukethwe
Kochwepheshe, lolu lwazi cishe ngeke lusebenziseke. Bazi kahle kakhulu yonke into ngezibhamu ezifuthwayo, basebenza nabo njalo futhi banezinto ezibalulekile okudala zisungulwe. Kodwa kubadwebi bezimoto abaqalayo, kanye nalabo abanesithakazelo sokwazi ubuchwepheshe bokudweba umzimba, ukuthenga imishini encane edingekayo kanye nokulondoloza ekuvuseleleni ukuhlobisa kwezimoto zabo noma ukusiza abangani, ulwazi oluthile mayelana nezibhamu ze-spray luyoba usizo.
Iyini isibhamu se-spray
Emdwebeni wokulungisa izimoto, zonke izinhlobo zamabhulashi nama-roller sekuyisikhathi eside zayeka ukusetshenziswa. I-can of paint ngaphansi kwengcindezi ngeke futhi inikeze ikhwalithi eyamukelekayo yokufaka. Ukuze imoto ibukeke ngendlela eyayibukeka ngayo lapho iphuma efektri, isibhamu somoya kuphela noma isibhamu sokufutha, njengoba sibizwa kanjalo ngokuba nesibhamu, ikani.
Iningi lezibhamu ze-spray lisebenza ngomgomo we-pneumatic. Kunomehluko omkhulu phakathi kwamamodeli athile, ahlotshaniswa nesifiso sabakhiqizi sokusondela ekupheleleni futhi kube lula umsebenzi womdwebi.
Kulungile, ingxenye yezidingo zekhono lomdwebi inganikeza ithuluzi elihle. Kodwa kuphela ekuqaleni, njengoba uthola ubuchwepheshe, isidingo sesibhamu esihle kakhulu sinxephezelwa ngolwazi. Kunoma yikuphi, okuningi kuncike kwikhwalithi yopende noma isifutho se-varnish.
Ukuthi isebenza kanjani
Wonke ama-atomizer asebenza ngendlela efanayo. Umoya ohlinzekwa ku-compressor ngaphansi kokucindezela okukhulu okuphawulekayo udlula esibambo sesibhamu, i-valve yokulawula bese ungena ekhanda le-annular. Phakathi nendawo kukhona umbhobho okunikezwa ngawo upende, othathwa yi-rarefaction of a fast air stream.
Uma usungenile emfudlaneni, upende ufuthwa ube amathonsi amancane, enze inkungu efana nethoshi. Ukuzinza ebusweni ukuze zidwetshwe, upende udala isendlalelo esifanayo, kusukela amaconsi amancane, angenaso isikhathi sokumisa, asakaze.
Ngokufanelekile, amaconsi mancane futhi awamanzi kangangokuthi indawo engaphezulu yakha isibuko ngaphandle kokupholisha okwengeziwe. Nakuba izibhamu zekhwalithi ephansi, ikakhulukazi ngaphansi kokulawulwa komdwebi we-novice, esikhundleni se-gloss, zizonikeza ubuso be-matte noma isakhiwo sokusiza esibizwa ngokuthi i-shagreen. Lokhu kungalungiswa ngokugaya nokupholisha okujulile ngokwanele, okuvame ukugwenywa ngabaphathi.
Idivayisi
I-airbrush iqukethe iziteshi nezilawuli zokuhlinzeka komoya, upende kanye nomzimba onesibambo, umklamo uhlanganisa:
- ukufaneleka kokuxhuma i-hose kusuka ku-compressor yomoya;
- izilawuli zokuhlinzeka komoya nopende (i-primer, i-varnish);
- ithangi likapende, lingaba phezulu noma phansi;
- fafaza ikhanda;
- i-valve yenaliti evumelanisa ukuhlinzekwa komoya nopende lapho i-trigger icindezelwa;
- izilawuli ezengeziwe, ikakhulukazi, ubukhulu bethoshi.
Yonke into ekwakhiweni kwesibhamu ingaphansi kokuhlinzeka ngezakhiwo eziningi zokufutha, ezivame ukuphikisana:
- ikhwalithi yokufutha, ukukhishwa kwamathe;
- ukunciphisa ukusetshenziswa kopende;
- ingcindezi ephansi kanye nezidingo zokusebenza kwe-compressor;
- izinhlobonhlobo eziningi ze-viscosities ezivumelekile zomkhiqizo ofuthiwe;
- ithoshi echazwe kahle yomumo olungisekayo enobuncane besifutho ngaphandle kwayo;
- ukufana kwesicelo.
Kulokhu, kuye kwasungulwa izindlela eziningi zokwenza izibhamu zokufutha ngezinhloso ezahlukene kanye nezigaba zamanani.
Izibhamu ze-HVLP
I-HVLP imele i-High Volume Low Pressure. Ngaphambi kokufika kwalobu buchwepheshe, izibhamu ze-spray zazisebenza ngomfutho womoya ophezulu eduze nombhobho, okunikeza i-atomization enhle, kodwa ukugeleza kopende okungamukeleki ngaphandle kwethoshi.
Ngokufika kwe-LVLP, lapho ukwakheka kunciphisa i-inlet 3 emkhathini ibe ngu-0,7 endaweni yokuphuma, ukulahlekelwa kuncishiswe kakhulu, amadivaysi esimanje adlulisela ku-70% womkhiqizo ofuthiwe endaweni efanele.
Kodwa njengoba ingcindezi iyancipha, ijubane lamaconsi kapende liyancipha. Lokhu kukuphoqa ukuthi ugcine isibhamu siseduze kakhulu nendawo, cishe amasentimitha ayi-15.
Okubangela ukuphazamiseka okuthile lapho usebenza ezindaweni okunzima ukufinyelela kuzo futhi kunciphisa isivinini somsebenzi. Yebo, futhi izidingo ze-compressor azikwazi ukuncishiswa, izinga lokugeleza likhulu, ukuhlanzwa kwekhwalithi ephezulu yobuningi bomoya obalulekile kuyadingeka.
Ukupenda izibhamu isigaba LVLP
Ubuchwepheshe obusha uma kuqhathaniswa bokukhiqiza izibhamu zokufutha, ezibonakala ngokuncipha kokusetshenziswa komoya (Ivolumu Ephansi). Lokhu kwakha ubunzima obubalulekile ekuthuthukisweni, izidingo ezinjalo ziphazamisa upende wesifutho wekhwalithi ephezulu. Kodwa ukucindezela kwe-inlet cishe kuyingxenye ephansi, okusho ukuthi ukuhamba komoya kuyehla.
Ukusebenza kahle kokudlulisa uyinki kuphezulu ngenxa yokuklama ngokucophelela, ngakho-ke ibanga lokuya phezulu linganyuswa lifike ku-30 cm ngenkathi kugcinwa i-coefficient yokudlulisa isezingeni elifanayo, uyinki usetshenziswa ngokonga njenge-HVLP.
Yini engcono i-HVLP noma i-LVLP?
Ngokungangabazeki, ubuchwepheshe be-LVLP busha, bungcono, kodwa bubiza kakhulu. Kodwa lokhu kuxazululwa yizinto eziningi ezinhle:
- umsebenzi oqondile ebangeni elengeziwe;
- izidingo eziphansi ze-compressor kanye nedivayisi yokuhlanza umoya;
- ukuminyana kwamalangabi afanayo;
- isivinini esihle;
- lula ukusebenza ezindaweni okunzima ukufinyelela kuzo;
- ukwakheka okuncane kwenkungu engaphandle yopende;
- ukwethembeka ekuguquguqukeni kwengcindezi yokungena.
Ngeshwa, lokhu kuza nobunzima obukhulayo kanye nezindleko. Izibhamu ze-LVLP spray zibiza izikhathi eziningi ezingeni elifanayo kunozakwabo be-HVLP. Singasho ukuthi eyokuqala izoba lula ukusetshenziswa ngabasebenzi abanamakhono aphansi, futhi izingcweti ezinolwazi zizobhekana nezibhamu ze-HVLP.
Futha ukulungiselelwa kwesibhamu
Kuyadingeka ukuqala umsebenzi ngokukhethwa kwemodi endaweni yokuhlola. Kufanele uye kuphela endaweni yokusebenza lapho yonke imingcele yesibhamu ilungiswa, ngaphandle kwalokho kuzodingeka ugeze yonke into noma uyigaye, ulinde ukuthi yome ngokuphelele.
I-viscosity yopende ilawulwa ngokungeza i-solvent kuyo efanelekile ngokukhethekile kulo mkhiqizo, ngokuvamile izinto ezitholakalayo zinikezwa ku-complex. Upende akufanele ufinyelele phezulu osuvele womile, kodwa ngesikhathi esifanayo akufanele udale ama-streaks.
Ukucindezela kwe-inlet kumele kulawulwe yi-gauge yokucindezela ehlukile, kufanele ihambisane nale modeli yesibhamu se-spray. Zonke ezinye zincike kule pharamitha. Ingase futhi isethwe ngokuhlolwa, izuze isifutho esifanayo ngaphakathi kwendawo lapho ukunikezwa kopende kanye nezilungiselelo zethoshi zingakulungi ngokugcwele.
Ubukhulu bethoshi bungancishiswa, kodwa kuphela ezimweni lapho kudingeka khona ngempela. Kuzo zonke ezinye, ukwehla kuzonciphisa umsebenzi kuphela. Kanye nokuhlinzekwa kopende, okunengqondo ukukhawulela kuphela nge-viscosity yayo ephansi kanye nokuthambekela kokudonsa. Ngezinye izikhathi kuyadingeka ukulungisa okuphakelayo ngisho noma indawo igcwaliswe ngokungalingani noma umumo wayo ovamile we-elliptical uhlanekezelwe.
Ungathwalwa yi-compressor pressure ephezulu kakhulu. Lokhu kuzomisa upende futhi kwehlise isiphetho esingaphezulu. Ukwakheka kwama-streaks kungagwenywa ngokuhambisa kahle ithoshi eceleni kwengxenye.
