Inayiloni Powder Electrostatic Spray Coating Inkqubo

Indlela yokutshiza ye-electrostatic isebenzisa isiphumo sokungenisa kwindawo yombane enevoltheji ephezulu okanye isiphumo sokutshaja sokukhuhlana ukwenza iintlawulo ezichaseneyo umgubo wenayiloni kunye nento egqunyiweyo, ngokulandelelanayo. Umgubo otyalwayo utsalwa kwinto etyatyekwe ngokuchasayo, kwaye emva kokunyibilika kunye nokumiswa, ukwambathisa inayiloni ifunyenwe. Ukuba imfuno yobunzima bokugquma ayidluli kuma-microns angama-200 kwaye i-substrate ayinayo intsimbi okanye i-porous, akukho kufudumala okufunekayo ukutshiza okubandayo. Ukugquma umgubo kunye neemfuno zobukhulu obungaphezulu kwe-microns ezingama-200 okanye i-substrates enentsimbi etyhidiweyo okanye izinto ezibunjiweyo, i-substrate kufuneka ifudunyezwe malunga ne-250 ° C ngaphambi kokutshiza, okubizwa ngokuba kukutshiza okushushu.

Ukutshiza okubandayo kufuna amasuntswana omgubo wenayiloni ukuba abe nobubanzi obumalunga ne-20-50 microns. Ngamanye amaxesha, inkungu yamanzi inokutshizwa ibe ngumgubo ukwandisa amandla ayo okuthwala iintlawulo kunye nokunciphisa iziphene ezibangelwa yilahleko yomgubo ngaphambi kokubhaka. Ukutshiza okushushu kufuna amasuntswana omgubo wenayiloni abe nobubanzi obufikelela kwi-100 microns. Amasuntswana arhabaxa anokubangela ukwambathisa, kodwa amasuntswana arhabaxa ngokugqithisileyo anokuthintela ukunamathela komgubo. Ngexesha lokutshiza okutshisayo, ukushisa kwe-substrate kuyancipha ngokuqhubekayo, okwenza kube nzima ukulawula ubukhulu, kodwa ukugquma akuyi kuvelisa iziphene zokulahlekelwa ngumgubo.

Inkqubo yokutshiza ye-electrostatic inoluhlu olubanzi lweenketho zokukhetha ubungakanani be-workpiece, ngokukodwa kwii-workpieces ezinobunzima obuhlukeneyo, ukuqinisekisa ukutyeba okufanayo. Xa i-workpiece ingagqunywanga ngokupheleleyo okanye inemilo entsonkothileyo engenako ukuntywiliselwa a ibhedi emanzi, inkqubo yokutshiza nge-electrostatic ineenzuzo. Ubushushu obuphezulu, iteyiphu yokuncamathela engagugiyo ingasetyenziselwa ukukhusela okwethutyana iindawo ezingagqunywanga. Ngokubanzi, ukutshiza nge-electrostatic kunokufikelela kwi-coating encinci, ephakathi kwe-150 microns kunye ne-250 microns. Ukongeza, i-nayiloni yokugquma efunyenwe ngokutshiza ngokubanda kwe-electrostatic inobushushu obuphantsi obunyibilikayo, ngokuqhelekileyo malunga ne-210-230 ° C imizuzu emi-5-10, ukuqina okulungileyo, kunye nokuthotywa kwe-thermal ephantsi. Ukubambelela kwisinyithi kungcono kunezinye iinkqubo.
