Nhanganyaya:
Roller coating yave nzira inosarudzika yekuisa machira paaluminium coil nekuda kwekuita kwayo uye kushanda kwayo. Nekuwedzera kuri kuda kwemhando yepamusoro uye yakasimba yakavharwa zvigadzirwa zvealuminium, roller coating yave nzira yakakosha muindasitiri yealuminium. Nekudaro, kuti uwane mhedzisiro inodiwa, zvakakosha kuti unzwisise izvo chaizvo zvekuita zvinodikanwa zveroller coating. Mune ino blog, isu tichaongorora zvakakosha zvekushanda zvinodiwa izvo roller coating coatings inofanirwa kuzadzisa, tichitarisa kune viscosity uye kuenzanisa zvivakwa, kukurumidza kurapa, kushongedza maitiro, uye kuramba mamiriro ekunze.
1. Yakakodzera viscosity uye yakanaka yekuyera zvivakwa:
Iyo roller coating process inosanganisira kukurumidza kudyisa bhandi, roller coating, kupisa kwakanyanya kubheka, uye nekukurumidza kutonhora. Kuti ive nechokwadi chekugadzirisa zvivakwa, zvakakosha kuti roller yekuputira ishandise huwandu hwakakwana hwepende pane iyo aluminium zvinhu. Naizvozvo, roller coating coatings inofanirwa kuve neyakakodzera viscosity uye yakanaka yekuyera zvivakwa. Iyo yekupfeka's viscosity inofanirwa kunyatso kugadzirwa kuti ibvumire kushandiswa kuri nyore uku ichichengetedza kugona kwayo kuenzana zvakaenzana pamusoro pealuminium. Kuwana iyo chaiyo viscosity chiyero kwakakosha mukudzivirira nyaya dzakaita senge kusaenzana kwekukoira ukobvu, mitsetse, uye orenji peel mhedzisiro.
2. Kukurumidza kurapwa:
Nekuda kwekumhanya-mhanya kwemaitiro ekugadzira roller coating mitsara, kukurumidza kupora chinhu chakakosha chinodiwa kune roller coating coating. Pasina tsigiro uye hurefu hushoma hwevheni yekubikira, nguva iripo yepende yekurapa inoderedzwa zvakanyanya. Mapendi anoshandiswa mukupfekedza roller anofanirwa kugadzirwa kuti arape mukati menguva pfupi, zviri nani zvisingasviki masekonzi makumi matanhatu. Pamusoro pezvo, nzira yekurapa inofanirwa kuchengetedza pendi iri pasi petembiricha yecoil ye260°C kudzivirira izvo zvinhu kubva pa deformation kana mamwe maitiro asina kunaka. Sarudzo yakakodzera yekunyungudutsa inodiwa kuti uwane kurapa nekukurumidza pasina kukanganisa kutendeseka kwejasi, kudzivirira zvinhu zvakajairika senge kubhubhura, mapini, uye kusamira zvakanaka.
3. Decorative features:
Kunze kwezvinhu zvinoshanda, roller coating coatings inofanirawo kusangana nezvinodiwa zvekushongedza. Pendi yepolyester inowanzokwana kuti uwane chitarisiko chinodiwa nechishandiso chimwe chete. Nekudaro, kana uchishandisa fluorocarbon coating, primer uye topcoat inodiwa kune yakakwana yekushongedza mhedzisiro. Iyo primer inofanirwa kuve neyakanakisa corrosion kuramba uye kunamatira kune ese substrate uye topcoat, nepo topcoat inofanirwa kuratidza yakanaka yekuvanda simba uye yekushongedza zvivakwa. Jasi rimwe chete rekutanga rinoteverwa nejasi rimwe chete retopcoat rinogona kuguma nekutaridzika kwakanaka kunosangana nezvose zvinoyevedza uye zvinoshanda zvinodiwa.
4. Kuramba kwemamiriro ekunze:
Roller coating coatings inofanirwa kuratidza yakasarudzika mamiriro ekunze, kunyanya kana ichiiswa kune ekunze zvigadzirwa zvealuminium. PVDF fluorocarbon coatings inowanzoshandiswa kupa mashandiro akazara kurwisa zvinhu zvakaita sekugara kwenguva refu, mvura ine acid, kusvibiswa kwemhepo, ngura, mavara akamira, uye mold. Zvichienderana nezvinodiwa zvenzvimbo, maviri, matatu, kana mana majasi ePVDF coating anogona kuiswa. Izvi zvinochengetedza kuchengetedzwa kwekugara kwenguva refu uye kusimba kwakanyanya, zvichibvumira iyo yakavharwa aluminium coil kuti imirire kunyangwe yakaomarara mamiriro ezvakatipoteredza.
Mhedziso:
Mukupedzisa, kuwana yakasarudzika roller coating performance for aluminium coils inoda kunyatsotariswa kweiyo coating's viscosity uye kuenzanisa zvivakwa, kukurumidza kurapa kugona, kushongedza, uye kuramba mamiriro ekunze. Nekunzwisisa uye kutevedzera izvi zvinodiwa pakuita, vagadziri vanogona kugadzira emhando yepamusoro yakavharwa zvigadzirwa zvealuminium zvinosangana nezvinodiwa zvemaindasitiri akasiyana. Sezvo kudiwa kwemacoil akavimbika uye anoyevedza ealuminium coil kuri kuramba kuchikura, zvakakosha kuti titarise kusarudzwa uye kushandiswa kwemaroller coatings ayo anogona kuzadzisa izvi zvakakosha kuita zvinodiwa.
