Dahaarka budada Heerkulbeegga ah ee buufinta Electrostatic
Sharaxaada kooban ee daahan budada ah
Qaabka dahaarka budada ah ee tignoolajiyada buufinta elektrostatic gabi ahaanba way ka duwan tahay dahaarka caadiga ah waxayna ku jiraan xaalada budada ganaaxa. Sababtoo ah ma jiro wax dareere ah, waxaa loo yaqaannaa dahaarka budada ah. Astaamaha ugu muhiimsan ee dahaarka budada ah waa: aan waxyeello lahayn, wax ku ool ah, kaydinta kheyraadka iyo deegaanka saaxiibtinimo.
Budada Thermosetting waa nooc caadi ahaan la isticmaalo oo ah budada buufinta korantada iyo mid ka mid ah kuwa ugu horreeya ee la sameeyo oo la marsado. Waxay leedahay qallafsanaan sare, caabbinta kiimikaad heer sare ah iyo iska caabin heerkul sare oo heer sare ah, waxaana si weyn loogu isticmaalaa daahan warshadaha, wax soo saarka, dhismaha iyo meelaha kale. Sida caadiga ah waxaa loo isticmaalaa budada heerkulbeegga ah waxaa ka mid ah epoxy, polyester, acrylate iyo polyeter.
Bandhiga Alaabta
Kala soocida caadiga ah
Dahaarka buufinta korantada ayaa guud ahaan loo qaybiyaa laba qaybood: dahaarka budada thermoplastic iyo daahanka budada heerkulbeegga.
1. Dahaarka budada Thermoplastic
Daboolka budada ah ee Thermoplastic wuxuu ka kooban yahay heerkulbeeg, midab, buuxin, xidhe iyo xasiliye. Dahaarka budada Thermoplastic waxaa ka mid ah: polyetylen, polypropylene, polyester, PVC, polyeter chlorinated, polyamide, cellulose, polyester iyo wixii la mid ah.
2. Dahaarka budada heerkulbeegga
Dahaarka budada kuleylku waxay ka kooban tahay xabagta heerkulbeegga, wakiilka daweynta, midabka, buuxinta iyo waxyaabaha lagu daro. Dahaarka budada Thermosetting waxaa ka mid ah: epoxy resin, epoxy polyester, polyester, polyurethane, resin acrylic iyo wixii la mid ah.
Faa'iidooyinka
Budada caaga ah waxaa loo qaybin karaa budada thermoplastic iyo budada heerkulbeegga; budada dibadda iyo budada gudaha; budada heerkulka-sare leh iyo budada heerkulka hooseeya.
1. Faa'iidooyinka budada caaga ah ee thermoplastic waa adag tahay, foorarsi wanaagsan, caabbinta kiimikada, waxaana lagu dabaqi karaa daboolka filimka qaro weyn.
2. Faa'iidada budada gudaha waa in waxqabadka uu ka daciifsan yahay budada dibadda, waxaa loo isticmaali karaa daahan workpiece gudaha, qiimuhu waa mid raqiis ah.
3. Budada heerkulka sare waxay u adkeysan kartaa heerkulka sare ee 200 darajo muddo dheer iyo daahan ma beddelo midabka, sifooyinka jireed iyo farsamada ee xadka la ogol yahay.
4. Thermosetting budada heerkulka qolka ma jilcin doono iyo agglomeration, kala firidhsan farsamo wanaagsan, fudud si ay u sameeyaan filim daahan siman.
5. Budada dibadda waxay ku habboon tahay daahan workpiece dibadda ah, oo leh antioxidant, anti-ultraviolet ray, anti-acid iyo ceeryaamo alkali iyo roobka, ballaarinta kulaylka wanaagsan iyo waxqabadka foosha.
6. Budada heerkulku hooseeyo waxay awood u yeelataa in ay gaadho aflaanta dahaarka ah 80-150 darajo Celsius, waxaana loo isticmaali karaa alwaax iyo caag.
