Ukucwangciswa kweSixhobo sokuSebenza sokuFakwa kwePowder

Zininzi iindlela zokufaka isicelo yengubo izixhobo; kwaye zisixhenxeral izixhobo isicelo ukutyabeka umgubo ukhetho. Nangona kunjalo, imathiriyeli eza kusetyenziswa kufuneka ibe luhlobo oluhambelanayo. Ngokomzekelo, ukuba indlela yokufaka isicelo ibhedi emanzi. ke izinto zokwaleka umgubo kufuneka ibe ibakala ibhedi fluidized, Ngokuchaseneyo, ukuba indlela yesicelo ukutshiza electrostatic, ngoko izinto umgubo kufuneka ibakala lokutshiza electrostatic.

Emva kokuba izinto ezikhethiweyo zikhethwe ngokuchanekileyo, ngoko indlela yokusetyenziswa ikhethwa yinxalenye yoyilo kunye neenjongo zokuvelisa. Kukho iindlela ezimbini zeendlela zokusetyenziswa. Ezi ziyohluka ngokubanzi njengoko izicelo zifaneleka.

Ezi fomu zezi:

1. Ukusetyenziswa kwebhedi emanzi
2. Ukutshiza isicelo.

IBHEDI EFLUIDIZED

Le ndlela yokusetyenziswa yaba yeyokuqala esetyenzisiweyo ukufaka izinto zokugquma umgubo. Isasetyenziswa nanamhla kwizicelo ezininzi apho ubukhulu befilimu obuphilisiwe bungaphezulu kwe-5.0 mils. Izinto eziqhelekileyo ziimveliso zocingo, imivalo yebhasi yombane, njl.

Indlela yokusetyenziswa kwebhedi enolwelo inokwenziwa ngeendlela ezimbini. Enye indlela yi. Le yinkqubo efuna ukufudumeza inxalenye ukwenzela ukuba i-powder iya kunyibilika kwaye ibambelele kuyo. Indawo eshushu ifakwa kumandlalo omanzi omgubo wokwaleka. Ubungakanani bepowder esetyenziselwa inxalenye ngumsebenzi wendlela eshushu ngayo inxalenye kunye nokuba ide kangakanani ebhedini. Kucacile ukuba ukulawulwa kobunzima befilimu ayiyona nto iphambili xa le ndlela isetyenziswa.

Ukufumana ulawulo olungakumbi lobunzima befilimu kwinqanaba, kunye nenkqubo yebhedi edibeneyo, imigaqo ye-electrostatics iyaziswa. Njengoko kuboniswe kwi-Fig. 1, inxalenye ithuthwa ngaphezu kwebhedi edibeneyo kwaye i-powder ikhange kuyo. Inxalenye ngoku ayifuni ukufudumeza ngaphambi kokuba ibekwe ngaphezulu kwebhedi. Umgubo utsalwa kwindawo ngokusebenzisa intlawulo ye-electrostatic kwisuntswana elingumgubo. Le ntlawulo ye-electrostatic iphuhliswa kwindawo ye-electrostatic nokuba ngaphezulu okanye kumandlalo olwelo.

Ubungqingqwa befilimu kwinxalenye ngoku bulawulwa hayi kuphela ixesha lenxalenye ekumandlalo olwelo, kodwa nokuba ingakanani intlawulo ye-electrostatic kwisuntswana lomgubo. Ubushushu busasetyenziswa ngamanye amaxesha kule nkqubo ukoyisa ubumbeko lwenxalenye enokubangela iingxaki zekheji yeFaraday.

Le ndlela yokusetyenziswa isetyenziselwa ukugquma izixhobo zombane zemoto. Ezi zifuna umbane ophezulu we-dielectric amandla kunye nokulawula ubukhulu befilimu ukuvumela ukuba ucingo lulimale ngokufanelekileyo.

Fluidized bed Ulwakhiwo luyahluka kumenzi ngamnye; nangona kunjalo, amacandelo asisiseko afanayo asetyenziswa kulo lonke uyilo. Ezi zixhobo ziyi-hopper okanye itanki, i-plenum okanye igumbi lomoya, kunye nepleyiti ye-fluidizing. Iimathiriyeli ezahlukeneyo zisetyenziselwa ngalinye kula macandelo kuxhomekeke kuyilo, kumvelisi, kunye nokusetyenziswa kokuphela. Umzekelo, ipleyiti ekhupha amanzi inokwenziwa ngeporous polyethylene, ibhodi yesandi, iphepha lobugcisa, okanye nayiphi na imathiriyeli enombhobho okanye indibaniselwano yemathiriyeli. Itanki ingenziwa nayiphi na into enokuxhasa ubunzima bomgubo.

ISICELO SOKUTSHELA

Indlela yokufaka umgubo wokugquma ngesixhobo sokutshiza i-electrostatic yahlulwe yazintlobo ezimbini. Kuzo zombini iimeko i-electrostatics kufuneka isetyenziswe ukutsala umgubo kwindawo.Tere akukho mtsalane womatshini okanye ukubambelela ukubamba. Umgubo kwindawo njengoko ubonwa kwiinkqubo zokutshiza ngolwelo. Ngoko ke, umgubo kufuneka uhlawulwe, okanye inxalenye eshushu (umtsalane we-thermal), ukukhangwa kwi-substrate. Umzekeliso ongcono kakhulu wokuchaza oku kukuba ukuba uhlikihla ibhaluni kwizinwele zakho, iya kubambelela eludongeni ngenxa yentlawulo ye-electrostatic. Ibhaluni efanayo ayiyi kubambelela eludongeni ngaphandle kwentlawulo ye-electrostatic. Olu lingelo kufuneka lwenziwe ngosuku olomileyo (lungafumileyo). Ezi ntlobo zimbini zezixhobo zokufakela umgubo wokutshiza we-electrostatic zezi:

1. imipu yokutshiza ye-corona.
2. I-Tribo ihlawulise imipu yokutshiza

Unyino lwe-amperage, ukukhwela ibhayisekile kwangoku okanye usetyenziso lwangoku oluphakathi longeza ixesha lokwaleka elifunekayo, ekubeni liyi-ampere-seconds esetyenzisiweyo (coulombs) evelisa i-electrodeposit.

Ukusetyenziswa kwangoku kuluhlu ukusuka malunga ne-15 coulombs ngegram yedyasi egqityiweyo ukuya kwi-150 coul / g. Emva kotyando lokuqala lwe-amperage, ukuxhathisa kombane okuphezulu kwefilimu esanda kufakwa kunciphisa ukuhamba kwangoku, okukhokelela kwi-ove.rall imfuneko ezimbini ukuya ezine amp ngonyawo square ukuya kwimizuzu enye ukuya kwemithathu, okanye phakathi kweyure enye nezithathu kilowatt nganye 100 square feet. Ukwaleka Ixesha lisusela kwimizuzu enye ukuya kwemithathu. Ngomsebenzi othile okhethekileyo, njengeingcingo. iibhendi zentsimbi, njl., amaxesha okugquma aphantsi njengemizuzwana emithandathu axelwe.

Imfuno yombane ilawulwa kakhulu yindalo ye-resin esasaziweyo kwindawo yokuhlambela. Ufakelo luhlala lusebenza phakathi kwe-200 kunye ne-400volts, nangona ezinye kuthiwa zisebenza ngaphantsi kwe-50 volts kwaye ezinye ziphezulu njenge-1000 volts.

Ukucoca:

Iingceba ezisandul’ ukugqunywa, xa ziphakanyiswa ebhafini, zithwala amathontsi ebhafu kunye namathontsi epeyinti. Uxinaniso oluphezulu lwezinto eziqinileyo zepeyinti zikhona kwindawo ekufutshane nesixhobo esaqatywayo. Kuqikelelwa ukuba umzimba wemoto unokuthwala (ukutsala ngaphandle) malunga negaloni enye yokuhlamba. Kwi-1wt% engaguquguqukiyo oku kumalunga ne-10 lb. Uthathela ingqalelo imfuduko yezinto eziqinileyo ukuya kumphezulu ogqunywe, ukugxila kokuqinileyo ukuya kuthi ga kwi-1% kulindelekile kwindawo yazo. Ngaloo ndlela, kuyacaca ukuba ukuhlanjululwa kwebhafu yepeyinti ephakanyisiweyo kuyimfuneko, kwaye indlela enengeniso ifunyenwe ngendlela "ye-ultrafiltrate rinse."

I-Ultrafiltration isebenzisa ii-membrane ezivumela ukuhamba kwamanzi kunye nezinto ezinyibilike ngokwenene, ezifana nezinyibilikisi, i-solubilizers, iityuwa (ukungcola!), njl njl. Ikhulu okanye ngaphezulu iilitha zokuhlambela zidlula kwelinye icala le-membrane phantsi koxinzelelo, ngelixa i-gallon ye-aqueous fluid ecacileyo idlula kwi-membrane. I-fluid, ebizwa ngokuba yi-permeate okanye i-ultrafiltrate, iyaqokelelwa kwaye isetyenziswe njenge-rinse fluid (Fig. 7). Inkqubo yokuhlanjululwa yamanqanaba amathathu ibuyisela malunga ne-85% yezinto eziqinileyo zepeyinti ezithe zaphakanyiswa ebhafini.

Izixa ze-ultrafiltrate ngamanye amaxesha ziyalahlwa, nto leyo enokwenza kube yimfuneko ukuthuthwa kweelori ukuya kwiindawo zokulahla. Umthamo wale nkunkuma unokuncitshiswa yi-osmosis eguqukayo.

Bhaka okanye Nyanga:

Iimfuno zexesha/ubushushu bokunyanga zilawulwa sisixokelelwano sentlaka kwaye ziyafana nezo zifunekayo kwidiphu eqhelekileyo okanye iipeyinti zokutshiza – ngokuqhelekileyo imizuzu emi-5-25 kubushushu bomoya obungama-250’F ukuya kuma-400°F. Ii-electrocoat zokomisa umoya zikwimarike.

IZIXHOBO

IiTanki zokugquma.

Zimbini iintlobo zeetanki ezisetyenziswayo:

1. Udonga lwetanki lusetyenziswa njenge-counter-electrode.
2. Udonga lwetanki lufakwe idyasi yokugquma ngombane, ngelixa i-counter-electrode ifakwe kwitanki emva koko ibekwe ngokobukhulu okanye ukumila kweqhekeza lomsebenzi. I-electrodes kwezinye iifakelo ezijikelezwe ngamacandelo, elinye icala lenziwe yinwebu. I-counter ion "X" okanye "Y" (Itheyibhile 1) iqokelela kwii-electrode compartments ngenkqubo ebizwa ngokuba yi-electrodialysis, kwaye ilahlwe okanye isetyenziswe kwakhona.

Ukuphazamiseka:
Iimpompo, iityhubhu eziqulunqiweyo, i-shafts ye-line shafts kunye ne-ejector-nozzle systems ezikwaziyo ukuhambisa okanye ukuguqula umthamo webhafu yonke kwimizuzu emi-6 ukuya kwengama-30 zisetyenziselwa ukuthintela ukuba ipeyinti ingazinzi etankini.

Fltration:
