Uzisebenzisa njani iiCoatings zePowder ye-Thermoplastic
Indlela yokusebenzisa ye i-thermoplastic powder coatings ikakhulu ziquka:
- Ukutshiza nge-Electrostatic
- Inkqubo yebhedi ene-fluidized
- Itekhnoloji yokutshiza iFlame
Ukutshiza nge-Electrostatic
Umgaqo osisiseko wale nkqubo kukuba umgubo we-electrostatic ukhokelwa kumphezulu we-workpiece yesinyithi phantsi kwesenzo esidityanisiweyo somoya ocinezelweyo kunye nentsimi yombane xa udlula isithuba phakathi kompu wokutshiza kunye nentsimbi yokusebenza yentsimbi.
I-powder ehlawulweyo ibambelela kumphezulu we-workpiece yensimbi ephantsi, emva koko iyancibilika kwi-oven kwaye ipholile ukuze ifumane i-coating ephezulu.Ubukhulu be-particle bukhethwe ngokungqongqo phakathi kwe-150-200µm.
Inkqubo yeFluidized Bed
Le nkqubo ifuna isikhongozeli somgubo esine-air pressure regulator.Umoya ocinezelweyo usasazeke ngokulinganayo kulo lonke isitya ngoncedo lwenwebu enemingxuma emazantsi esitya, yenza umgubo weplastiki ubilise njengolwelo.
Xa umgubo we-thermoplastic kulo mandlalo we-fluid udibana ne-workpiece yentsimbi eshushu ngaphambili, umgubo osondeleyo kuyo unamathela kumphezulu wayo kwaye uyanyibilika. Emva koko intsimbi iyaphakanyiswa kwaye ipholiswe ukuze yenze isambatho somgangatho ophezulu.
Zombini amasuntswana acolekileyo narhabaxa afanelekile kule nkqubo.
Itekhnoloji yokutshiza iFlame
I-powder ye-thermoplastic ixutywa ngomoya ocinezelweyo kwaye ifakwe kwi-flame gun. Umgubo ke utofwa ngedangatye ngesantya esiphezulu. Ixesha lokuhlala lepowder elangatyeni lifutshane kodwa lanele ukunyibilikisa ngokupheleleyo amasuntswana omgubo. Amasuntswana anyibilikisiweyo ngendlela yamathontsi abonakala kakhulu afakwa kwi-substrate, enze ifilimu engqindilili ekuqinisweni.
Le ndlela yobugcisa isetyenziselwa izinto ezingenakufudunyezwa okanye ezingangeni kwi-oven ye-industrial.
Enye indlela yokusebenzisa i-thermoplastic powder coatings ine-rotary lining process.
