Iindlela zokuBeka iPowder – ELECTROSTATIC SPRAYING
Ukutshiza nge-Electrostatic yeyona ndlela isetyenziswa kakhulu yokufaka yengubo izixhobo. Ukukhula kwayo kuyanda ngesantya esichukumisayo. Iphuhliswe phakathi kwe-60, le nkqubo yeyona ndlela isebenzayo yokufaka iingubo kunye nokugqiba ngexesha elifutshane. Nangona kunjalo, ukwamkelwa kwengubo yomgubo kwi-general ekuqaleni yayicotha kakhulu e-US. EYurophu, ingqikelelo yokutshiza yomgubo we-electrostatic yamkelwa ngokulula, kwaye itekhnoloji yahamba ngokukhawuleza kakhulu kunenye indawo emhlabeni. Nangona kunjalo, ukuqhubela phambili okuninzi kwenziwa kuzo zombini izixhobo zomgubo kunye nezixhobo zokusebenza ezifumanekayo kubavelisi. Ezi ziphuculo zofuzorally ibandakanye iingxaki ezinxulumene ne-electrostatic powder spray coating, kunye nokuphucula ukusebenza kwamacandelo enkqubo. Ngenxa yoko, kukho iintlobo ngeentlobo zeenkqubo zokugquma kwe-electrostatic powder spray ezikhoyo namhlanje.
Ukusebenzisa izixhobo zokugquma umgubo ngenkqubo yokutshiza yomgubo we-electrostatic, kufuneka izixhobo ezisisiseko ezintlanu:
- iyunithi yokutyisa umgubo;
- Umpu we-electrostatic powder spray, okanye isixhobo esilinganayo sokusabalalisa;
- Umthombo wamandla ombane we-electrostatic;
- iyunithi yokubuyisela umgubo;
- Ukutshiza umnquba
Kukho ezinye izixhobo zokuphucula ukusebenza kwala malungu asisiseko. Ekusebenzeni kwenkqubo yokutshiza yomgubo we-electrostatic, umgubo utsalwa, okanye umpontshwe, ukusuka kwiyunithi yesondlo kusetyenziswa umbhobho wesondlo somgubo ukuya kwi(imipu yokutshiza). Amandla okuqhubela phambili abonelelwa ngomoya othutha umgubo ukusuka kwiyunithi yesondlo ukuya kumpu wokutshiza, kunye nentlawulo ye-electrostatic enikezelwe kumgubo kumpu. Umbane wombane we-electrostatic unikezelwa kumpu wokutshiza ngumthombo owenzelwe ukuhambisa amandla ombane aphezulu, anomlinganiselo ophantsi wombane kwi-electrode (s) encanyathiselwe kumpu wokutshiza. Njengoko ifu elisasaziweyo, elichajiwe nge-electrostatically lomgubo lisondela kwindawo ephantsi, indawo yombane yokutsala iyadalwa, itsala amasuntswana omgubo kwindawo kwaye yenze umaleko womgubo. I-overspray-okanye umgubo ongabambeleli kwinxalenye-iqokelelwa ukuze isetyenziswe kwakhona okanye ilahlwe. Kwiyunithi yomqokeleli, umgubo uhlukaniswe kwi-airflow ehambisayo. Umgubo oqokelelweyo uye uphinde usetyenziswe ngokuzenzekelayo okanye ngesandla ubuyiselwe kwiyunithi yesondlo ukuze uphinde utshizwe. Umoya ugqithiselwa kwisixhobo semidiya yokuhluza ukuya kwiplenum yomoya ococekileyo kwaye emva koko ugqitywe, okanye ngokupheleleyo, ukucoca ubuyele kwindawo yesityalo njengomoya ococekileyo. Inxalenye egqunyiweyo ithwalwa ukusuka kwindawo yesicelo kwaye iphantsi kobushushu, okukhokelela ekuphumeni kunye nokunyangwa kwezinto zomgubo.
Inzuzo Yezoqoqosho
Nge-electrostatic powder spray, ukuya kuthi ga kwi-99% yomgubo we-powder overspray unokufunyanwa kwaye ugatywe kwakhona. Ilahleko yezinto eziphathekayo efunyenwe ngomgubo incinci xa kuthelekiswa neenkqubo zokugquma ulwelo.
Ukongeza, kwiimeko ezininzi umgubo ubonelela ngengubo enye ngaphandle kokubaleka kunye ne-sags kwindawo egqityiweyo. Ukusebenzisa a kuqala Idyasi ngaphambi kokugqiba idyasi ayiyomfuneko, ukunciphisa ixesha kunye nomsebenzi ofunwa ziinkqubo zolwelo lwe-multicoat.
Ukwehliswa kweendleko zamafutha kumgubo wokunyanga kaninzi kubangelwa kusetyenziso lwee-oveni ezincinci, amaxesha amafutshane e-oveni kwaye, kwezinye iimeko, amaqondo asezantsi e-oveni. Akukho mfuneko yokufudumeza okanye ukucaphuka i-makeup ye-booth kuba umoya ubuyiselwa kwindawo yesityalo njengomoya ococekileyo.
Okunye ukongiwa kweendleko, kubandakanywa iindleko ezisezantsi zokucoca, kunokufunyanwa ngomgubo. Akukho mfuneko yokuxuba, ukubuyisela, kunye nokulahla izinyibilikisi xa uqatywe ngomgubo. Ngesiqhelo, akukho sinyibilikisi okanye iikhemikhali ezisetyenziswayo ekucoceni isixhobo sokufaka umgubo okanye iidokodo zokutshiza. Ekubeni izicoci zomoya kunye ne-vacuum ziyi-generally yonke into efunekayo yokucoca nge powder, abasebenzi kunye nezinto zokucoca ziyancipha kwaye ukulahlwa kwe-sludge yepeyinti eyingozi kupheliswa.
Ipesenti enkulu yeengubo zolwelo iqulethwe ngamanye amaxesha enetyhefu kunye ne-solvent evuthayo elahlekileyo kwinkqubo yesicelo. Ukugcinwa kwezinto ezithunyelwayo, kunye neendleko zokuphatha izinyibilikisi ziqhele ukubiza kakhulu. Ngomgubo, iindleko ezibandakanya isixhobo sokulawula ukungcoliseka kwendalo, ixesha lokukhanya, kunye nokulahlwa kwenkunkuma enyibilikayo ziphelisiwe.
Ukuphelisa ukusetyenziswa kwe-solvent kunokunciphisa iimfuno ze-inshurensi yomlilo kunye neerhafu ezihlawulwayo ukugcina ukhuseleko lwe-inshurensi yomlilo. Okokugqibela ixabiso elisetyenzisiweyo nge-mil nganye ngesikwere sonyawo lwefilimu lilingana, okanye lisezantsi kuneendleko zokugquma ulwelo kwiimeko ezininzi.
Ukusebenziseka lula
Iimpawu zokugqiba ezingaguqukiyo kunye "ne-wraparound" ye-electrostatic efunyenwe kwizicelo zokutshiza ngomgubo zinceda ukunciphisa imfuno yabaqhubi abanezakhono eziphezulu. Ukongezelela, akukho lungelelaniso lwe-viscosity yokugcina xa ugubungela nge powder. Izinto zomgubo ziza "zilungele ukutshiza" kumenzi. Akukho xesha lifunwayo ngumgubo. Inxalenye egqunyiweyo inokuthuthwa ngokuthe ngqo ukusuka kwindawo yokutshiza ukuya kwi-oven ukunyanga. Amaxabiso okwala anokuncitshiswa, njengoko kunokwenzeka neendleko ezibandakanyekayo ekusebenzeni ngokutsha iinxalenye ezaliweyo. Ii-runs kunye neesags zivame ukupheliswa kunye nenkqubo yokugquma umgubo.
Ukutya okungonelanga okanye okungafanelekanga kunokuvuthela inxalenye (ngaphambi kokunyangwa kobushushu) kwaye iphinde ifakwe. Oku kunokuphelisa umsebenzi kunye neendleko ezibandakanyekayo ekuhlubeni, ukubuyisela kwakhona, ukubuyisela, kunye nokubuyisela iindawo ezikhatywayo. Inokusebenzisa izithuthi zompu ezizenzekelayo, iindlela zokujikela, iirobhothi, kunye nokuma okumileyo kwemipu. Ixesha elipheleleyo lemveliso linokuncitshiswa rhoqo, okanye umthamo wemveliso unyuswe, ngokugquma ngomgubo wokutshiza. Ukuphelisa amanyathelo ahlukeneyo afunekayo kunye nenkqubo yokugubungela ulwelo kunokubangela umgca wokugqiba ngokufanelekileyo.
