Iyo Fluidized Bed Powder Coating Inoshanda Sei?
Fluidized bed poda coating inzira yekupfekedza substrate nehupfu hwakatsetseka. Maitiro acho anosanganisira kumisa hupfu murukova rwemhepo, kugadzira mubhedha wakanyungudika wehupfu unobvumira kunyange kupfekedzwa kweiyo substrate. Munyaya ino, tichaongorora sei fluidized bed poda coating anoshanda.
Maitiro ekuputira mubhedha poda yekuputira inogona kuputswa kuita mashanu makuru steps: substrate kugadzirira, poda kushandiswa, preheating, kunyunguduka uye kurapa.
Danho 1: Kugadzirira kweSustrate Danho rekutanga mune yakanyunguditswa mubhedha poda yekupotera maitiro kugadzirira substrate. Izvi zvinosanganisira kuchenesa substrate kubvisa chero tsvina, girisi kana zvimwe zvinosvibisa zvinogona kudzivirira hupfu kuti husamira zvakanaka. Iyi nhanho yakakosha pakubudirira kwemaitiro, sezvo chero zvinosvibisa pane substrate zvinogona kukanganisa kunamatira uye kusimba kwejasi.
Danho rechipiri: Powder Kushandisa Kana iyo substrate yachena uye yakaoma, yakagadzirira danho rekushandisa hupfu. Hupfu hwehupfu hunowanzo chengetwa muhopi kana mugaba, umo hunoyereswa kunze uchishandisa mudziyo wekuparadzira. Chishandiso chekuparadzira chinogona kugadziridzwa kuti chidzore huwandu hwehupfu huri kuiswa, kuve nechokwadi chekuti ukobvu hwekuputira hunoenderana nepakati pe substrate.
Danho rechitatu: Preheating Mushure mekunge poda yashandiswa, substrate inotanga kupisa. Iyi nhanho inofanirwa kunyungudutsa hupfu uye kugadzira yunifomu yekuputira pane substrate. Tembiricha ye preheating process ichaita depeuye pahupfu hwehupfu huri kushandiswa, asi hunowanzobva pa180 kusvika pa220 degrees Celsius.
Danho rechina: Kunyunguduka Kana iyo substrate yave yave kupisa, inonyudzwa mumubhedha wakanyoroveswa wehupfu. Iyo poda inorembera murukova rwemhepo, ichigadzira mubhedha unoyerera wakakomberedza substrate. Sezvo iyo substrate inodzikiswa mumubhedha wemvura, zvimedu zvehupfu zvinonamatira kumusoro kwayo, zvichigadzira jira rakafanana.
Kupisa kunobva pakupisa kunokonzeresa kuti hupfu hunyunguduke uye huyerere pamwe chete, huchiita firimu rinoramba riripo pane substrate. Kunyunguduka kunowanzotora pakati pemasekonzi makumi maviri kusvika makumi matatu, depending pahupamhi hwejasi uye kutonhora kwemubhedha wemvura.
Nhanho yechishanu: Kurapa Danho rekupedzisira mune yakanyungudutswa mubhedha poda yekuputira maitiro iri kurapa. Kana iyo yekuputira ichinge yaiswa, inopisa kusvika pakupisa kwepamusoro kuti iporese hupfu uye kugadzira iyo yakasimba, inogara kwenguva refu. Kurapa tembiricha nenguva zvinozoita depeuye pahupfu hwehupfu huri kushandiswa, asi hunowanzobva pa150 kusvika ku200 madhigirii celsius kwemaminetsi gumi kusvika gumi nemashanu.
Munguva yekurapa, iyo poda particles crosslink uye kemikari inopindirana kuti igadzire yakasimba, yakasimba coating inonamatira kune substrate. Iyo nzira yekurapa yakakosha pakuona kuti iyo yekupfeka inogara yakasimba, kuramba kune abrasion, uye makemikari kuramba.
Mukupedzisa, fluidized bed powder coating inzira inoshandiswa uye inoshanda yekuputira substrates nehupfu hwakatsetseka. Nzira yacho inosanganisira kugadzirira substrate, kushandiswa kwehupfu, preheating, kunyunguduka, uye kuporesa, chimwe nechimwe chakakosha pakubudirira kwekuputira. Nekunzwisisa kuti fluidized bed powder coating inoshanda sei, unogona kuita zvisarudzo zvine ruzivo nezvekuti maitiro aya akakodzera kune yako application.
