Kuti tikwaniritse zofunikira zama projekiti osiyanasiyana, timapereka matekinoloje osiyanasiyana opaka pamwamba ogwirizana ndi nyengo komanso zofuna za msika. Timapereka chithandizo chamankhwala chosinthidwa makonda pazogulitsa zathu zonse, kutengera zomwe kasitomala amakonda, komanso kupereka malingaliro akatswiri.
Anodizing vs. Powder Coating
Gome lotsatirali likuwonetsa kufananitsa kwachindunji pakati pa anodizing ndi zokutira za ufa monga njira zomaliza.
| Anodizing | Kupaka Powder |
| Zitha kukhala zoonda kwambiri, kutanthauza kusintha pang'ono chabe pamiyeso ya gawolo. | Amatha kukwaniritsa malaya wandiweyani, koma ndizovuta kupeza wosanjikiza woonda. |
| Kusiyanasiyana kwakukulu kwamitundu yachitsulo, yokhala ndi zomaliza zosalala. | Zosiyanasiyana modabwitsa mumitundu ndi mawonekedwe zitha kukwaniritsidwa. |
| Ndi kukonzanso koyenera kwa ma electrolyte, anodizing ndiyothandiza kwambiri zachilengedwe. | Palibe zosungunulira zomwe zimakhudzidwa ndi ntchitoyi, zomwe zimapangitsa kuti zisawonongeke kwambiri. |
| Kuvala bwino, zokanda, ndi kukana dzimbiri. | Kukana bwino kwa dzimbiri ngati pamwamba ndi yunifolomu komanso yosawonongeka. Itha kuvala ndikukanda mosavuta kuposa anodizing. |
| Imakana kuzirala kwa mtundu bola ngati utoto womwe wasankhidwa uli ndi kukana koyenera kwa UV pakugwiritsa ntchito ndikusindikizidwa bwino. | Imagonjetsedwa kwambiri ndi kuwala kwa ultraviolet. |
| Amapangitsa kuti aluminiyumu ya pamwamba ikhale yamagetsi kuti ikhale yosagwiritsa ntchito. | Zina zamagetsi mu zokutira koma osati zabwino ngati aluminium opanda kanthu. |
| Ikhoza kukhala njira yokwera mtengo. | Zotsika mtengo kuposa anodizing. |
Aluminiyamu mwachilengedwe amapanga wosanjikiza wopyapyala wa okusayidi pamwamba pake akakhala ndi mpweya. Wosanjikiza wa oxide uyu ndi wopanda pake, kutanthauza kuti samachitanso ndi malo ozungulira - ndipo amateteza zitsulo zonse kuzinthu.
Anodizing
Anodizing ndi mankhwala opangira zida za aluminiyamu omwe amapezerapo mwayi pagawo la oxide iyi pokulitsa. Akatswiri amatenga chidutswa cha aluminiyamu, monga gawo lotulutsidwa, ndikuchimiza mu bafa la electrolytic, ndikuyendetsa magetsi.
Pogwiritsa ntchito aluminiyumu monga anode mu dera, ndondomeko ya okosijeni imapezeka pamwamba pa chitsulo. Zimapanga oxide wosanjikiza wokhuthala kuposa momwe zimachitikira mwachilengedwe.
Kupaka ufa
Kupaka ufa ndi mtundu wina wa kumaliza ntchito pazitsulo zosiyanasiyana. Njirayi imapangitsa kuti pakhale chitetezo komanso chokongoletsera pamwamba pa mankhwala omwe amachiritsidwa.
Mosiyana ndi ntchito zina zokutira (mwachitsanzo, kujambula), kupaka ufa ndi ntchito youma. Palibe zosungunulira zomwe zimagwiritsidwa ntchito, zomwe zimapangitsa kuti ufa ukhale wothandizana ndi chilengedwe kusiyana ndi mankhwala ena omaliza.
Pambuyo poyeretsa gawolo, katswiri amagwiritsira ntchito ufawo mothandizidwa ndi mfuti ya spray. Mfutiyi imagwiritsa ntchito mphamvu yolakwika ya electrostatic ku ufa, zomwe zimapangitsa kuti zikopeke ndi gawo lachitsulo. Ufawo umakhalabe womangiriridwa ku chinthucho pamene wachiritsidwa mu uvuni, kutembenuza malaya a ufa kukhala yunifolomu, wosanjikiza wolimba.
Zojambula za PVDF
Zopaka za PVDF zimakwanira pakati pa gulu la mapulasitiki a fluorocarbon, omwe amapanga zomangira zomwe zimakhala zokhazikika pamankhwala komanso kutenthetsa. Izi zimathandiza mitundu ina ya zokutira ya PVDF kuti ikwaniritse nthawi zonse kapena kupitilira zofunika zolimba (monga AAMA 2605) zomwe sizizimiririka pakapita nthawi yayitali. Mutha kudabwa momwe zokutira izi zimayikidwa.
Njira Yogwiritsira Ntchito PVDF
Zopaka za PVDF za aluminiyamu zimayikidwa m'chipinda chojambulira ndi mfuti yamadzimadzi yopaka utoto. Njira zotsatirazi zikuwonetsa ndondomeko yonse yomaliza zokutira za PVDF zapamwamba:
- Kukonzekera Pamwamba- Chophimba chilichonse chapamwamba chimafuna kukonzekera bwino pamwamba. Kumatira kwabwino kwa PVDF kumafunikira kuyeretsa, kuchotsera mafuta, ndi kuchotsa dzimbiri (kuchotsa dzimbiri) pamwamba pa aluminiyamu. Zovala zapamwamba za PVDF ndiye zimafunikira kugwiritsa ntchito zokutira zosinthika za chrome kuti zigwiritsidwe ntchito isanayambike.
- Choyamba- The primer imakhazikika bwino ndikuteteza pamwamba pazitsulo ndikuwongolera kumamatira kwa zokutira pamwamba.
- PVDF Top zokutira- Tinthu tating'ono ta pigment timawonjezedwa komanso kugwiritsa ntchito zokutira pamwamba. Chophimba chapamwamba chimathandiza kuti chophimbacho chisawonongeke ndi kuwala kwa dzuwa ndi madzi, komanso kuwonjezeka kwa abrasion resistance. Chophimbacho chiyenera kuchiritsidwa pambuyo pa sitepe iyi. Chophimba chapamwamba ndi chokhuthala kwambiri mu dongosolo la zokutira la PVDF.
- PVDF Chophimba Choyera- Mu 3-wosanjikiza PVDF yophimba ndondomeko, chomaliza chomaliza ndi chophimba chomveka bwino, chomwe chimapereka chitetezo chowonjezereka kuchokera ku chilengedwe ndipo chimalola mtundu wa topcoat kupyolera popanda kuwonetsa kuwonongeka. Chophimba ichi chiyeneranso kuchiritsidwa.
Ngati pakufunika ntchito zina, njira ya 2-coat kapena 4-coat ingagwiritsidwe ntchito m'malo mwa njira ya malaya a 3 omwe afotokozedwa pamwambapa.
Ubwino Waikulu Wogwiritsa Ntchito Zopaka za PVDF
- Okonda zachilengedwe kuposa zokutira zoviika, zomwe zimakhala ndi ma volatile organic compounds (VOCs)
- Kusamva kuwala kwa dzuwa
- Kugonjetsedwa ndi dzimbiri ndi choko
- Kusamva kuvala ndi abrasion
- Imakhalabe ndi mawonekedwe amtundu wapamwamba (imakana kuzimiririka)
- High kukana mankhwala ndi kuipitsa
- Zokhalitsa ndi zosamalitsa zochepa
Kuyerekeza PVDF ndi zokutira Powder
Kusiyana kwakukulu pakati pa zokutira za PVDF ndi zokutira zaufa ndikuti zokutira za PVDF:
- Gwiritsani ntchito utoto wamadzimadzi wokhazikika, pomwe zokutira zaufa zimagwiritsa ntchito ufa wopaka pamagetsi
- Ndi zoonda kuposa zokutira zaufa
- Ikhoza kuchiritsidwa kutentha kwa chipinda, pamene zokutira za ufa ziyenera kuphikidwa
- Amalimbana ndi kuwala kwa dzuwa (ma radiation a UV), pomwe zokutira zaufa zimazimiririka pakapita nthawi ngati zikuwonekera
- Itha kukhala ndi mapeto a matte, pamene zokutira zaufa zimatha kubwera mumitundu yambiri komanso zomaliza
- Ndiokwera mtengo kuposa zokutira za ufa, zomwe ndi zotsika mtengo ndipo zimatha kupulumutsa ndalama zowonjezera pogwiritsanso ntchito ufa wopopera.
Kodi Ndivale Aluminiyamu Yomanga Ndi PVDF?
Zitha kutengera momwe mumagwiritsira ntchito koma ngati mukufuna zolimba kwambiri, zosagwirizana ndi chilengedwe, komanso zotulutsa aluminiyamu zotalikirapo kapena zopindika, zokutira za PVDF zitha kukhala zoyenera kwa inu.
