Low Temperature Solidified Powder Coating
General Sumo:
Ichi chigadzirwa chifukidziro chehupfu chakagadzirwa neforoma yakakosha uye maitiro ekugadzira, ayo akakodzera MDF yekupfekedza. Iyo yekuputira firimu ine yakanakisa mechaniki zvivakwa uye yemukati yekushongedza zvivakwa. Inogona kushandiswa zvakanyanya kupfekedza pamusoro muindasitiri yemazuva ano fenicha. Kazhinji hazvikurudzirwe kuisa zvakananga kumusoro kwemarudzi ese ezvigadzirwa zvekunze.
Product Series:
Ikozvino inogona kugadzirwa mumhando dzakasiyana dzemavara uye simbi inopenya mhedzisiro yejecha kana sando yekunamira zviyo.
Zvinhu Zvenyama:
Chaiyo giravhiti (g/cm3, 25℃): 1.2-1.8
Particle saizi kugovera: 100% isingasviki 100micron (Inogona kugadziridzwa zvinoenderana neakakosha zvinodiwa zvekupotera)
Mamiriro ekuvaka:
Electrostatic pfapfaidzo pfuti inogona kushandiswa kupfekwa, ukobvu hwefirimu hwakakodzera kudzora mu70-90 micron. (MDF substrate ichave yakafanopiswa zvakafanana ne infrared oven pamberi, uye chaiyo yekudziya tembiricha ichatemwa zvichienderana nekupisa kweMDF substrate.)
Curing Conditions:
120 ℃ (inoreva MDF ndiro pamusoro tembiricha), maminitsi makumi maviri. Oveni inogona kushandisa yakajairwa yemhepo inopisa yekutenderera ovheni kana nzira yekuomesa, mamiriro acho anobvumira akanakisa kutanga SHANDISA iyo infrared ray oveni kupfapfaidza iyo yakanaka yekuputira kuti ienderere mberi nekupisa kwekuyerera kuyerera, yozotumira yakajairika hovhoni kuti ibike kuti iome.
Coating performance:
| Testing chinhu | Kuongorora mwero kana nzira | Test zviratidzo |
| kukanganisa kuramba | ISO 6272 | 50kg.cm |
| cuping test | ISO 1520 | 5mm |
| simba rekunamatira (row lattice method) | ISO 2409 | 0 level |
| kukotama | ISO 1519 | 2mm |
| kuoma kwepenzura | ASTM D3363 | 1H-2H |
| munyu spray test | ISO 7253 | >500 maawa |
| bvunzo inopisa uye yakanyorova | ISO 6270 | >1000 maawa |
Notes:
1.Miedzo iri pamusoro yakashandiswa 0.8mm gobvu inotonhora-yakakungurutswa simbi mahwendefa ane coating ukobvu 30-40 microns mushure mureza pretreatment.
2.Indekisi yekushanda yejasi iri pamusoro inogona kuchinja nekuchinja kwe gloss uye unyanzvi hwekuita.
Avhareji yekuvhara:
nezve 8-9 sq.m. 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:
Chengetedza mukamuri ine mhepo inofefetera, yakaoma uye yakachena pa30 ℃, isiri padyo nenzvimbo yemoto, kupisa kwepakati uye kudzivirira zuva rakananga. Zvinorambidzwa zvachose kuunganidza pachena. Pasi pemamiriro ezvinhu aya, hupfu hunogona kuchengetwa kwemwedzi mitanhatu. Mushure mehupenyu hwekuchengetedza hunogona kuongororwa zvakare, kana zvigumisiro zvichisangana nezvinodiwa, zvinogona kushandiswa. Midziyo yese inofanirwa kurongedzerwa uye kurongedzerwa 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.
