Epoxy Powder Coating
Product sumo:
Epoxy poda coating inogadzirwa kubva epoxy resin ine akasiyana zvivakwa uye Chelsea inorapa mumiririri. Iyo inoratidzirwa nekuchengetedza simba, kusvibiswa kwakaderera uye kushanda kwakanyanya. Haisi chete inogona kunge iri firimu, kukwenenzverwa kwekupfeka kwakakwira, uye iyo yekumusoro coating anti-corrosion performance yakanaka, yakakwira mechanical simba.
Iyo poda yekuputira inonyanya kushandiswa mukuvaka, kushongedza, midziyo yemumba, simbi fenicha, zviridzwa, mugwagwa mukuru guardrail, zvikamu zvemotokari, kusimba kwemitambo yemitambo coating uye mamwe maindasitiri.
General sumo:
Epoxy resin inoshandiswa sechinhu chikuru mbishi. Iyo ine yakanakisa makemikari kuramba uye mechanical properties. Inokodzera kupfekedza zvigadzirwa zvesimbi zvine zvakakwirira zvinodikanwa pakudzivirira kusvibiswa, magetsi ekudzivirira uye kushanduka. Kazhinji hazvikurudzirwe kuisa zvakananga kumusoro kwemarudzi ese ezvigadzirwa zvekunze.
Chikamu chekushandisa:
Penda simbi pamusoro pezvikamu zvemotokari, midziyo yemumba, simbi fenicha, zvivakwa zvehofisi uye akasiyana marudzi emapombi.
Product series:
Kupa mureza uye yakaderera tembiricha solidified poda coating; Inogona kugadzirwa kuita zvigadzirwa zvine mwenje wakakwira (80% kumusoro), semi-light (50-80%), flat light (20-50%) uye isiri-yechiedza (pasi pe20%). (Gloss inogona kudzorwa zvinoenderana nezvinodiwa nevashandisi).
Zvinhu zvemuviri:
Chaiyo giravhiti (g/cm3, 25℃): 1.4-1.7
Particle saizi kugovera: 100% isingasviki 100micron (Inogona kugadziridzwa zvinoenderana neakakosha zvinodiwa zvekupotera)
Mamiriro ekuvaka:
Pretreatment: Yakasiyana pretreatment inoshandiswa kune akasiyana substrates (phosphating kurapwa, jecha blasting kurapwa, kupfura peening kurapwa, ndapota taura nesu kuti uwane rumwe ruzivo)
Fluidized bed, vacuum suction, roller coating, manual kana automatic electrostatic pfuti nedzimwe nzira dzinogona kushandiswa kuvaka.
Kurapa mamiriro:
Type A: 200 ℃ (workpiece tembiricha), 15 min (flat kana flat)
Type B 180 ℃ (workpiece tembiricha), 15 min (kusimbisa kana semi-gloss)
Type C 140 ℃ (workpiece tembiricha), 15 min (kusimbisa)

Notes:
1.Mayedzo ari pamusoro akashandisa 0.8mm gobvu-akakungurutswa simbi mahwendefa ane coating ukobvu hwe60-80 microns.
2.Indekisi yekushanda yejasi iri pamusoro inogona kuderera zvishoma nekuderera kwe gloss.
Avhareji yekuvhara:
9-12 sq.m./kg; firimu ukobvu 60 microns (akaverengerwa 100% poda coating kushandiswa mwero);
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.
Kuchengeta zvinodiwa:
Yakachena, yakaoma, ine mhepo, kure nechiedza, tembiricha yemukamuri iri pasi pe30 ℃, uye inofanira kuvharirwa kubva pamoto, kure nekupisa. Uye kana insulate sosi yemoto, chengetedza kure nekupisa. Nguva yekuchengetedza inoshanda ndeye 12 mwedzi kubva pazuva rekugadzirwa. Dzivisa stacking anopfuura mana akaturikidzana.
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.
