Njira Zogwiritsira Ntchito Ufa - ELECTROSTATIC spraying

Kupopera kwa electrostatic ndiyo njira yomwe imagwiritsidwa ntchito kwambiri popaka ufa wophimba zipangizo. Kukula kwake kukukulirakulira pamlingo wochititsa chidwi. Yopangidwa pakati pa zaka za m'ma 60, njirayi ndiyo njira yabwino kwambiri yogwiritsira ntchito zokutira ndikumaliza mu nthawi yochepa. Komabe, kuvomereza kupaka ufa mu jiniral poyamba anali wochedwa kwambiri mu US. Ku Ulaya, mfundo electrostatic ufa kutsitsi anavomerezedwa mosavuta, ndi luso anasuntha mofulumira kwambiri kumeneko kuposa kwina kulikonse padziko lapansi. Komabe, kupita patsogolo kwambiri kunachitika muzinthu zonse za ufa ndi zida zogwiritsira ntchito zomwe opanga amapanga. Izi zowonjezera jinirally adakhudzanso mavuto okhudzana ndi zokutira zopopera za electrostatic powder, komanso kukonza magwiridwe antchito azinthu zamakina. Chotsatira chake, pali mitundu yambiri ya electrostatic ufa kutsitsi ❖ kuyanika kachitidwe zilipo lero.
Kuyika zida zokutira ufa ndi electrostatic ufa kutsitsi ndondomeko, zidutswa zisanu zofunika zida:

• Powder feeder unit;
• Electrostatic powder spray mfuti, kapena chipangizo chofanana chogawa;
• Gwero lamagetsi a electrostatic;
• Chigawo chobwezeretsa ufa; 
• Utsi nyumba

Palinso zida zina zolimbikitsira kugwira ntchito kwa zigawo zoyambira izi. Pogwira ntchito ya electrostatic powder spray system, ufa umasefedwa, kapena umapopedwa, kuchokera ku feeder unit kudzera papaipi yaufa kupita kumfuti. Mphamvu yothamangitsira imaperekedwa ndi mpweya womwe umanyamula ufa kuchokera ku feeder unit kupita ku mfuti ya spray, komanso ndi electrostatic charge yoperekedwa ku ufa pamfuti. Mphamvu yamagetsi yamagetsi imaperekedwa kumfuti yopopera ndi gwero lopangidwa kuti lipereke mphamvu yamagetsi yothamanga kwambiri, yotsika pang'ono ku ma elekitirodi omwe amamangiriridwa kumfuti yopopera. Monga diffused, electrostatically nayimbidwa ufa mtambo pafupi gawo pansi, malo magetsi kukopa analengedwa, kukoka particles ufa ku gawo ndi kupanga wosanjikiza ufa. Overspray-kapena ufa wosatsatizana ndi gawolo-amasonkhanitsidwa kuti agwiritsidwenso ntchito kapena kutaya. Mu gawo losonkhanitsa, ufa umasiyanitsidwa ndi mpweya wotumizira. Ufa umene wasonkhanitsidwa umangotengedwa kuti ubwezedwenso pawokha kapenanso pamanja kuti ukautsiridwenso. Mpweya umadutsa mu chipangizo chosefera kupita ku mpweya wabwino ndipo kenako kudzera mu sefa yomaliza, kapena mtheradi, kubwereranso kumalo omera ngati mpweya wabwino. Gawo lokutidwa limatengedwa kuchokera kumalo ogwiritsira ntchito ndikutenthedwa, zomwe zimabweretsa kutuluka ndi kuchiritsa kwa zinthu za ufa.

Ubwino Wachuma

Ndi electrostatic ufa kutsitsi, mpaka 99% ya ufa overspray akhoza kuchira ndi kupakanso. Kutayika kwa zinthu zopezeka ndi ufa ndizochepa poyerekeza ndi makina opaka madzi.
Kuonjezera apo, nthawi zambiri ufa umapereka chivundikiro cha malaya amodzi popanda kuthamanga ndi sags pa gawo lomalizidwa. Kugwiritsa ntchito a phunziroli Chovala chisanafike kumapeto sikofunikira, kuchepetsa nthawi ndi ntchito zomwe zimafunidwa ndi machitidwe amadzimadzi a multicoat.
Kutsika kwa mtengo wamafuta pochiritsa ufa nthawi zambiri kumabwera chifukwa chogwiritsa ntchito ma uvuni ang'onoang'ono, nthawi yaufupi ya uvuni, nthawi zina, kutentha kutsika kwa uvuni. Palibe chifukwa chotenthetsa kapena kutenthetsa mpweya wopaka mpweya chifukwa mpweya umabwerera kumalo omera ngati mpweya woyera.
Kuchepetsa ndalama zina, kuphatikiza zotsika mtengo zoyeretsa, zitha kupezedwa ndi ufa. Palibe chifukwa chosakaniza, kubwezeretsa, ndi kutaya zosungunulira popaka ufa. Nthawi zambiri, palibe zosungunulira kapena mankhwala omwe amagwiritsidwa ntchito poyeretsa zida zopangira ufa kapena malo opopera. Popeza mpweya ndi vacuum zotsukira ndi majinirally zonse zomwe zimafunika pakutsuka ndi ufa, zogwirira ntchito ndi zoyeretsera zimachepetsedwa ndikutaya utoto woyipa wa utoto kumathetsedwa.
Zambiri mwa zokutira zamadzimadzi zimakhala ndi zosungunulira zapoizoni komanso zoyaka moto zomwe zimatayika popanga. Kusungirako katundu, ndi kusamalira zosungunulira ndizokwera mtengo kwambiri. Ndi ufa, mtengo wokhudzana ndi zida zowongolera kuwononga chilengedwe, nthawi yozimitsa, ndi kutaya zinyalala zosungunulira zimathetsedwa.
Kuchotsa kugwiritsa ntchito zosungunulira kungachepetsenso zofunikira za inshuwaransi yamoto komanso mitengo yolipiridwa kuti iteteze inshuwaransi yamoto. Pomaliza mtengo wogwiritsidwa ntchito pa mil pa sikweya mapazi a filimuyo ndi wofanana, kapena wotsika kuposa, mtengo wokutira wamadzimadzi nthawi zambiri.

Kusavuta Kugwiritsa Ntchito

Makhalidwe omalizira okhazikika ndi "kuzunguliridwa" kwa electrostatic komwe kumadziwika popopera ufa kumathandiza kuchepetsa kufunikira kwa ogwira ntchito aluso kwambiri. Kuphatikiza apo, palibe mamasukidwe akayendedwe oyenera kukhalabe popaka ndi ufa. Zida za ufa zimabwera "zokonzeka kupopera" kuchokera kwa wopanga. Palibe nthawi yowunikira yomwe imafunikira ndi ufa. Gawo lokutidwa limatha kunyamulidwa kuchokera pamalo opopera kupita ku uvuni kuti lichiritsidwe. Kukana mitengo kungachepe, monga momwe kungachepetsere ndalama zomwe zimakhudzidwa pokonzanso magawo omwe adakanidwa. Kuthamanga ndi ma sags nthawi zambiri amachotsedwa ndi njira yopaka ufa.
Kupaka kosakwanira kapena kosayenera kumatha kuwulutsidwa mbaliyo (kutentha kusanachiritsidwe) ndikubwezeretsanso. Izi zikhoza kuthetsa ntchito ndi ndalama zomwe zimakhudzidwa ndi kuvula, kukonzanso, kubwezeretsanso, ndikubwezeretsanso magawo okanidwa. Itha kugwiritsa ntchito zoyendetsa mfuti zokha, makina ozungulira, maloboti, komanso kuyimitsa mfuti. Nthawi yonse yopanga imatha kuchepetsedwa, kapena kuchuluka kwa kupanga kumawonjezeka, ndi zokutira zopopera ufa. Kuchotsa masitepe osiyanasiyana ofunikira ndi njira yokutira yamadzimadzi kumatha kubweretsa mzere womaliza.
