Polyester Resin Powder Coating
General Sumo:
Yakagadzirwa necarboxyl polyester resin, pigment filler uye TGL seanorapa agent, ine super weather resistance uye UV kuramba. Yakanaka michina zvivakwa, kuomarara kwepamusoro, kuramba kwekukwenya, kusagadzikana kwekuora; Yakanaka yekuenzanisa midziyo, iyo firimu haina mahara pinholes, shrinkage maburi uye humwe hurema; Inogona kushandiswa kune zvigadzirwa zvekunze zvesimbi zvakadai semhepo inogadzirisa, mwenje yekunze uye mwenje.
Product Series:
kupa zvakakwirira (80% pamusoro), semi-mwenje (50-80%), girazi rakajeka (20-50%) uye hapana- mwenje (20% pazasi) zvigadzirwa kana pane zvinodiwa
Zvinhu Zvenyama:
Chaiyo giravhiti (g/cm3, 25℃) : 1.2-1.7
Particle saizi kugovera: 100% isingasviki 100 micron (Inogona kugadziridzwa zvinoenderana nezvinodiwa zvekupendi)
Mamiriro ekuvaka:
Pretreatment: nzvimbo yacho inofanira kunyatsocheneswa kubvisa mafuta uye ngura. Iko kushandiswa kwesimbi yakatevedzana phosphating kana yakakwira mwero zinc series phosphating inogona kuwedzera kuvandudza kugona kwekudzivirira.
Kurapa maitiro: manual kana otomatiki static pfuti kuvaka
Kurapa mamiriro: 190-200 ℃ (workpiece tembiricha), maminitsi gumi

Notes:
1.Iwo maedzo ari pamusoro akashandisa 0.8mm gobvu-akakungurutswa simbi mahwendefa ane coating ukobvu hwe30-40 microns mushure mekutanga kurapwa.
2.Indekisi yekushanda yejasi iri pamusoro inogona kuderera zvishoma nekuderera kwe gloss.
Avhareji yekuvhara:
8-11 sq.m./kg; firimu ukobvu 70 microns (akaverengerwa ne100% poda coating utilization rate)
Kurongedza uye chekufambisa:
makatoni akaiswa mabhegi epolyethylene, huremu hwemambure i20kg; Zvinhu zvisina ngozi zvinogona kutakurwa nenzira dzakasiyana-siyana, asi chete kudzivirira zuva rakananga, unyoro uye kupisa, uye kudzivirira kusangana nemakemikari zvinhu.
Zvido zvekuchengeta:
Yakachena, yakaoma, inofefetera, kure nechiedza, tembiricha yekamuri iri pasi pe30 ℃, uye inofanira kunge yakavharidzirwa kubva pamoto, kure nekupisa. Mushure menguva yekuchengetedza, inogona kuongororwa zvakare uye kushandiswa zvakare kana zvigumisiro zvinosangana nezvinodiwa. Yese midziyo inofanirwa kurongedzerwa uye kudzoserwa kune yayo yekutanga kurongedza mushure mekushandiswa.
Notes:
Mapoda ese ari kutsamwisa kumweya wekufema, saka dzivisa kufemesa hupfu uye chiutsi kubva pakurapa. Edza kudzivisa kusangana kwakananga pakati peganda uye poda coating. Geza ganda nemvura nesipo pazvinenge zvakakodzera. Kana maziso akasangana, geza ganda nekukurumidza nemvura yakachena uye tsvaga kurapwa nekukurumidza. Dust layer uye poda particle deposition inofanira kudzivirirwa pamusoro uye pakona yakafa. Tiny organic particles anobatidza uye kukonzera kuputika pasi pemagetsi akamira. Midziyo yese inofanirwa kudzika pasi, uye vashandi vekuvaka vanofanirwa kupfeka anti-static shangu kuchengetedza pasi kudzivirira magetsi akamira.
