Ubungakanani be-particle ye-analsis yokusabalalisa umgubo

Ubungakanani besuntswana lokuhlalutya ukuhanjiswa kwe yengubo

Iziphumo zovavanyo lwe-laser particle size analyzer:

I-avareji yobungakanani be-particle (i-diameter ephakathi), umda we-particle size kunye ukuhanjiswa kobungakanani besuntswana yokusasazwa.

1. Ubungakanani obuqhelekileyo besampulu bungaphantsi kwaye bungaphezulu kwama-50% amasuntswana.
2. Ubungakanani bomda wamasuntswana: kufutshane nengqiqo ukuya kubukhulu kunye nobuncinci besayizi yamasuntswana. Nangona kunjalo, ubungakanani obuphezulu kunye nobuncinci besayizi yamasuntswana ukuchaza imida ephezulu kunye nesezantsi yesampulu yobungakanani besuntswana elingenasayensi, lufuzo.ralI-ly boundary particle size, njenge (D10, D90) = (8,60), imele i-microns engaphantsi kwe-8 kwi-diameter particles ibalwa kwi-10% kunye ne-90%, inani leengqungquthela ezincinci kune-60 microns ububanzi.
3. Ukusasazwa kobungakanani bamasuntswana obungakanani = (D90-D10) / D50, ukusasazwa, okuncinci ukuhanjiswa kobungakanani bamasuntswana kukumxinwa kakhulu, kukhulu kakhulu kwaye kuncinci kakhulu inani lamasuntswana kubungakanani bamasuntswana obuncinci buphezulu boxinzelelo.

Ubudlelwane phakathi kobungakanani besuntswana kunye nomgangatho womgubo:

Ukusabalalisa ubungakanani be-particle kunye nokuthungwa kwefilimu, i-smoothness, i-gloss, umphumo we-particle, iziphumo eziphilayo, i-powder fluidization, ukuzinza kokugcinwa kunye nesantya sokubuyisela umgubo kuhambelana ngokusondeleyo.

1. Imbonakalo, umgangatho, kunye nesuntswana: Kwimfuzaral, incinci isayizi ye-powder particle, ingcono ukugudisa kwipeyinti yokunyanga; ubungqingqwa obufanayo bokugquma, ubungakanani besuntswana elincinci lomgubo alukho lula ukubonakala ngamasuntswana; ukubonakala kwengubo igudileyo ngakumbi, igudileyo.
2. iziphumo eziphilayo kunye nesivuno somgubo: Uhlawuliswa ukuphucula amaqhekeza empuphu, i-powder yokugqoka i-powder kwizinga iya kwandiswa. Amandla obhengezo angundoqo womgubo wokutshiza we-electrostatic, isivuno somgubo sixhomekeke kubungakanani bamasuntswana omgubo ohlawuliweyo. Umgubo onamandla kunye nobungakanani beqhekeza lepuphu lilingana nesikwere. Ukwandisa ubungakanani bamasuntswana, umgubo ngokusetyenziswa okuphezulu, izinga lomgubo. Ubungakanani bamasuntswana omgubo bukhulu kakhulu, ubukhulu besuntswana elikhulu kakhulu, umxhuzulane womgubo wesuntswana elikhulu phezu kwe-aerodynamic kunye ne-electrostatic powder coating ngexesha lokubhabha, iye yawa ngenxa yomxhuzulane ayifikeleli kumphezulu, kodwa ukwenza izinga lomgubo. Umgubo ocoliweyo kakhulu ohlawuliswayo ophantsi komgangatho wesicelo uya kuhla, umgubo we-ultra-fine (ubungakanani besuntswana <10μm) ngokusisiseko awuhlali ngexesha elinye umgubo ucolekile kakhulu kwaye kwandisa ubunzima bokuvelisa umgubo.
3. Isiphumo sokuhamba komgubo: Umgubo umncinci kakhulu, umncinci kakhulu uya kuthwala irejimeni yomgubo odibeneyo, ukusasazwa akusayi kusasazeka. Xa utshizwe kwi-workpiece ukwenza i-sleek kunye nencinci, ichaphazela ukubonakala kwengubo. Xa umgubo ungumgubo orhabaxa kakhulu kumbhobho womgubo akukho lula ukuqukunjelwa.
4. Ukuzinza kokugcinwa: Ukuzinza kubhekisela kwi-powder coating phantsi kweemeko ezithile, ukugcina ubungakanani bepowder particle, shape and hardness capability, oko kukuthi, nokuba i-powder kwisitoreji okanye ukusetyenziswa kuya kubamba umswakama, ukwenzeka kwezinto ezifana ne-powder caking. Ngokuqhelekileyo umgubo ocolekileyo kakhulu, ngakumbi umxholo womgubo we-ultrafine ongaphantsi kwe-10μm kakhulu umgubo kulula ukufunxa ukufuma, amaqela amaqhina, ukuncipha kozinzo, uya kuplaga umpu, utshice umgubo kakubi.
5. Izinga lokubuyisela: Isityalo sokuvelisa umgubo kunye nesityalo sepeyinti yomgubo kukho umba wokuphinda usetyenziswe umgubo wokutyabeka, ngokuqhelekileyo, ubungakanani besuntswana lomgubo <10μm izinga lokubuyisela umgubo we-ultra-fine liphantsi, xa ubukhulu beqhekeza lomgubo> 10μm pm izinga lokunyuka ngokukhawuleza, kunye nomgubo Isantya sokubuyisela sanda njengoko ubungakanani be-particle sanda.

Ukufakwa kwepowder ukwenza ukubaluleka kokufumanisa ubungakanani be-particle ubungakanani befomula efanayo, isikhokelo sokuvelisa umgubo, ukusebenza kwepowder ukuphumeza ubuninzi bokusebenza.
