Izixhobo zokutshiza nge-Electrostatic

Uthuli lwezixhobo zombane yengubo eyaziwa njenge "electrostatic spray". Isitshizi sinokuba semanuwali, sizenzekela okanye sibe semanyuwali + sizenzekela. I-100% yezinto zokutshiza ngumgubo oqinileyo, ii powders zasimahla zinokuphinda zisebenzise ireyithi yokugaywa kwepeyinti ukuya kuthi ga kwi-98%. Ukunqunyanyiswa kwenkqubo yezothutho, iqondo eliphezulu lokuzenzekelayo. I-microporous egqunywe kancinci, ukuxhathisa okuhle kokubola, kwaye inokuba yifilimu eshinyeneyo.

Electrostatic powder ukutyabeka esekelwe ukuba atomizing Tsui (ipeyinti atomizing), kunye nenqanaba lokukhupha (intlawulo yangoku kwenzeka) umatshini yokwaleka ukwenzela ukuba amasuntswana ipeyinti, isetyenziswe izibini intlawulo kwaye intsimi yombane yenziwa phakathi electrode kunye. into eza kugqunywa, usebenzisa i-electrostatic adsorption coating.

Inkqubo yokwaleka komgubo we-Electrostatic yavela ngeminyaka yoo-1960, isetyenziswa ikakhulu kukwaleka umphezulu wesinyithi. Ngasekupheleni kweminyaka yoo-1990 ukuya kwinkulungwane yama-20, ngophuhliso lwezixhobo zokugquma umgubo kunye nokutshiza, inkqubo yokwaleka yomgubo we-electrostatic isetyenziswa kwinto engeyiyo.zetsimbi umphezulu onokwenzeka.

Kunye nemithetho yokusingqongileyo yeemfuno ezingqongqo ngakumbi kumxholo womoya wezinto eziphilayo eziguquguqukayo (voc), ishishini lokwaleka lizama ukuphuhlisa itekhnoloji yokwaleka emodareyithayo kokusingqongileyo, izixhobo zothuli zeNingbo ezifunyenwe emva kophando lwexesha elide kunye novavanyo lomgubo we-electrostatic. ukutyabeka ukufezekisa iteknoloji yokwambathisa ecocekileyo.

I-powder yokugcoba ayisebenzisi i-solvent ye-organic, amanzi kunye nezinye izinyibilikisi eziguquguqukayo, i-solvent-based based based coatings, enciphisa kakhulu i-solvent ngenxa yenkathazo yokungcola okubangelwa yityhefu yabasebenzi abasebenzayo, kuquka i-solvent equlethe; ayiyi kuphumela kwi-solvent ephilayo kwaye ibangele umlilo.Ukususela kwi-powder coating ekhoyo ngoku, ayizange ibangele izingozi ezinkulu ngenxa ye-powder coating.

I-powder yokwaleka yinto yokwaleka, icandelo elisulungekileyo eliqinileyo linokuba ngokuzenzekelayo ukutshiza umgubo omkhulu okanye omkhulu wokutshiza waqokelelwa ngokulula yinkqubo yokubuyisela, ukufezekisa injongo yokuphinda kusetyenziswe. Ngoko ke, izinga lokusetyenziswa kwe-powder coating liphantse lifike kwi-100%, okwenza imboni yokugubungela ukunciphisa iindleko zokulahla inkunkuma, kwaye kwangaxeshanye inokunciphisa ubuninzi bokungcoliseka kwendalo. Inzuzo ebalulekileyo yezoqoqosho.

I-coating film-forming component, i-solvent-type malunga ne-60% ukuya kwi-65%, ngelixa i-powder yokugqoka i-powder inokufezekiswa phantse i-100% esebenzayo, kwaye ingaqhotyoshelwanga kwinto yokutshiza i-powder ingaphinda isetyenziswe. Kwiimeko eziqhelekileyo, ukusetyenziswa kweteknoloji yokugqoka i-powder kwi-peyinti ingaba yinto enokwenzeka ukufezekisa uqoqosho kunye nokusebenza kakuhle. Kwi-powder coating operation, ukuba kukho iindawo ezimbi zokutshiza zingangena ngaphandle kokubhaka, usebenzisa i-air spray gun ihlanjululwe, kwaye uphinde upeyinte. Ke ngoko, ukunqanda ukuhamba komphezulu wepeyinti kuwisa into yepeyinti, kunciphisa kakhulu ithuba lokuphinda usebenze kwakhona.

Ukusebenzisa imisebenzi yokutshiza ye-electrostatic ngenxa yokugquma ngumgubo, izixhobo zokupeyinta phantse ukuya kuthi ga kwi-automated ngokupheleleyo, ukusindisa umthombo womntu. Nokuba yenziwe, ukupeyinta ixesha elide loqeqesho akuyomfuneko ukuba ukwazi kakuhle izakhono zokusebenza. I-powder yokugqoka i-100% yokubunjwa kwezinto eziqinileyo, ngaphandle kokufaka nayiphi na i-solvent, isixa sokugubungela siyancipha, sigcina ukupakishwa, ukunciphisa indawo yokugcina.
