Ndeipi airbrush iri nani pane HVLP kana LVLP: misiyano uye kuenzanisa kwehunhu
Zviri mukati
Kune nyanzvi, ruzivo urwu harugone kubatsira. Vanoziva zvese nezve pfuti dzekupfapfaidza zvakanyanya, shanda navo nguva dzose uye vane nguva refu yakasimbiswa sarudzo dzekutanga. Asi kune vanotanga mapendi emota, pamwe neavo vanofarira kugona tekinoroji yekupenda muviri, kutenga zvigadzirwa zvishoma zvinodiwa uye kuchengetedza pakushongedza kwekuzorodza kwemotokari dzavo kana kubatsira shamwari, rumwe ruzivo nezve pfuti yekupfapfaidza ichave yakakosha.
Chii chinonzi spray gun
Pakugadziridza mota, marudzi ese emabhurashi nema rollers akarega kushandiswa kwenguva refu. Chigaba chepende pasi pekumanikidzwa hachizopiwo hutano hunogamuchirwa hwekuvhara. Kuti motokari itaridzike zvakafanana neyayaiva nayo payakabva mufekitari, ingori bhurashi remhepo kana kuti pfuti yokupfapfaidza, sokudanwa kwainoita kuva nepistol grip, gaba.
Iyo yakawanda yepfuti yekupfapfaidza inoshanda pane pneumatic musimboti. Kune misiyano mizhinji pakati pemamodeli chaiwo, ayo anobatanidzwa nechishuwo chevagadziri kuti vaswedere kukwana uye kufambisa basa remupendi.
Ndizvozvo, chikamu cheunyanzvi hunodiwa nemhizha inogona kupa chishandiso chakanaka. Asi chete pakutanga, paunowana hunyanzvi, kudiwa kwepistol yakanakisa kunotsiviwa neruzivo. Chero zvazvingava, zvakawanda zvinoenderana nehutano hwepende kana varnish sprayer.
Ainoita
Maatomizer ese anoshanda nenzira imwechete. Mhepo inopihwa kubva kune compressor pasi pekunyanya kudzvinyirira inopfuura nemubato wepfuti, iyo valve yekudzora uye inopinda mumusoro we annular. Pakati payo pane muromo wepende inopihwa, inotorwa nearefaction yemhepo inokurumidza mhepo.
Kana yangopinda murukova, pendi yacho inopfapfaidzwa mumadonhwe maduku, kuita mhute yakaita setochi muchimiro. Kugadzika pamusoro pekuti kuve nekupenda, pende inogadzira yunifomu jira, kubva madonhwe maduku, asina nguva yekuoma, kupararira.
Sezvineiwo, madonhwe madiki uye anoyerera zvekuti kumusoro kunoumba girazi kupera pasina kumwe kukwenenzverwa. Kunyange zvazvo mapistol emhando yakaderera, kunyanya ayo ari pasi pekutonga kweanovice painter, achapa matte pamusoro kana chimiro chekuyamura chinonzi shagreen pachinzvimbo chegloss. Izvi zvinogona kugadziriswa nekudzika zvakaringana nekukuya uye kupukuta, izvo izvo vatenzi vanowanzo dzivirira.
Device
Iyo airbrush ine machaneli uye ekufambisa emhepo regulators, pendi uye muviri une mubato, dhizaini inosanganisira:
- kukodzera kwekubatanidza hose kubva kune air compressor;
- mhepo uye pendi inopa regulators (primer, varnish);
- tangi yepende, inogona kuva pamusoro kana pasi;
- pfapfaidza musoro;
- chivharo chetsono chinofananidza kugoverwa kwemhepo uye pendi kana iyo trigger inodzvinyirirwa;
- mamwe maregulator, kunyanya, ukuru hwetochi.
Zvese zviri mukugadzirwa kwepfuti zviri pasi pekupa huwandu hwezvivakwa zvekupfapfaidza, kazhinji zvichipokana:
- kupfapfaidza kunaka, kusabatwa nekupfira;
- kuderedza kushandiswa kwepende;
- low pressure uye compressor performance zvinodiwa;
- zvakasiyana-siyana zvinobvumirwa viscosities yechigadzirwa chakapfapfaidzwa;
- mwenje wakanyatsotsanangurwa wechimiro chinogadziriswa chine zvishoma zvekupfapfaidza kunze kwayo;
- application kufanana.
Nokuda kweizvi, nzira dzinoverengeka dzakagadzirwa kugadzira pfuti dzekupfapfaidza nekuda kwezvinangwa zvakasiyana uye mapoka emitengo.
HVLP pfapfaidzo pfuti
HVLP (High Volume Low Pressure) zvinoreva huwandu hwemhepo yekupfuura nepamhepo yakaderera. Tisati tauya tekinoroji iyi, pfuti dzakapfapfaidza dzakashanda nemhepo yakakwira pedyo nemuromo, iyo yakapa atomization yakanaka, asi isingagamuchirwi zvachose pendi inoyerera kunze kwetochi.
Nekuuya kweLVLP, uko dhizaini inoderedza inlet 3 atmospheres kusvika 0,7 pakubuda, kurasikirwa kwakaderedzwa zvakanyanya, zvishandiso zvemazuva ano zvinoendesa kusvika 70% yechigadzirwa chakapfapfaidzwa kunzvimbo chaiyo.
Asi sezvo dzvinyiriro inodzikira, kumhanya kwemadonhwe ependi kunodererawo. Izvi zvinokumanikidza kuti uchengete pfuti iri pedyo zvakanyanya nepamusoro, inenge 15 centimita.
Izvo zvinokonzeresa kumwe kusagadzikana kana uchishanda munzvimbo dzakaoma-kusvika-uye kuderedza kukurumidza kwebasa. Hongu, uye zvinodikanwa zvecompressor hazvigone kuderedzwa, kuyerera kweyero yakakura, yemhando yepamusoro kuchenesa kweakakosha mhepo inodiwa.
Kupenda pfuti chikamu LVLP
Zvinei tekinoroji nyowani yekugadzira pfuti yekupfapfaidza, inoratidzwa nekuderedzwa kwemhepo kushandiswa (Low Volume). Izvi zvakagadzira matambudziko akakura mukusimudzira, zvinodiwa zvakadaro zvinokanganisa pendi yemhando yepamusoro yekupfapfaidza. Asi inlet pressure inenge hafu yakawandisa, zvinoreva kuti kuyerera kwemhepo kunodzikira.
Iyo inki yekuchinjisa inobudirira yakakwirira nekuda kwekunyatso dhizainira, saka chinhambwe chepamusoro chinogona kuwedzerwa kusvika masendimita makumi matatu uchichengetedza coefficient yekutamisa padanho rimwe chete, iyo inki inopedzwa sehupfumi seHVLP.
Chii chiri nani HVLP kana LVLP
Pasina mubvunzo, tekinoroji yeLVLP inyowani, iri nani, asi inodhura. Asi izvi zvinodzikiswa nehuwandu hwezvakanakira:
- basa rakarurama pamwero wakawedzerwa;
- yakaderera zvinodiwa compressor uye mhepo yekuchenesa mudziyo;
- yunifomu murazvo density;
- kukurumidza kwakanaka;
- kusununguka kwebasa munzvimbo dzakaoma-kusvika;
- kuumbwa kudiki kwemhute yekunze yepende;
- kuvimbika kune inlet pressure kuchinja.
Zvinosuruvarisa, izvi zvinouya nekuwedzera kuoma uye mutengo. Pfuti dzekupfapfaidza dzeLVLP dzinodhura kakawanda padanho rimwe chete kupfuura mamwe maHVLP. Tinogona kutaura kuti yekutanga ichave nyore kushandisa nevashandi vashoma-hunyanzvi, uye mhizha dzine ruzivo dzichasangana neHVLP pistols.
Spray pfuti setting
Izvo zvinodikanwa kuti utange basa nekusarudzwa kweiyo mode pane test surface. Iwe unofanirwa kuenda chete kunzvimbo yekushanda apo zvose zvigadziro zvepfuti zvakagadziriswa, kana zvisina kudaro iwe uchafanira kushambidza zvinhu zvose kana kuzvikuya, kumirira kuti zviome zvachose.
Iyo viscosity yepende inogadziriswa nekuwedzera solvent kwairi iyo yakakodzera zvakananga kune chigadzirwa ichi, kazhinji zvinhu zvinopiwa mumatambudziko. Iyo pende haifaniri kusvika pamusoro iyo yakatooma, asi panguva imwechete haifaniri kuumba mitsetse.
Iyo inlet pressure inofanirwa kudzorwa neyakasiyana gauge yekumanikidza, inofanirwa kuenderana neiyi modhi yepfuti yekupfapfaidza. Vamwe vese vanotsamira pane iyi parameter. Inogona zvakare kusetwa mukuyedza, kuwana yunifomu yekupfapfaidza mukati meiyo nzvimbo nependi yekupihwa uye zvigadziriso zvetochi zvisina kuvharwa.
Ukuru hwetochi hunogona kuderedzwa, asi chete mumamiriro ezvinhu apo inodiwa chaizvo. Mune mamwe ose, kuderera kunongoderedza basa. Pamwe chete nekupihwa kwepende, izvo zvine musoro kudzikamisa chete neiyo yakaderera viscosity uye tsika yekudonha. Dzimwe nguva zvinodikanwa kugadzirisa chikafu kunyangwe nzvimbo yacho yakazadzwa zvisina kuenzana kana chimiro chayo che elliptical chakakanganiswa.
Usatakurwe neakanyanya compressor pressure. Izvi zvinoomesa pende uye kuderedza kupera kwepamusoro. Kuumbwa kwemitsara kunogona kudziviswa nekufambisa zvakanaka tochi pamwe chete nechikamu.
