Makhalidwe a YC-8102 High-Temperature Yosindikizidwa Anti-oxidation Nano-Composite Ceramic Coating (Yellow Yowala)
Zida zigawo ndi maonekedwe
(Zovala za ceramic zokhala ndi gawo limodzi
Madzi otumbululuka achikasu
Ntchito gawo lapansi
Chitsulo cha carbon, chitsulo chosapanga dzimbiri, chitsulo chotayira, aluminium aloyi, titaniyamu aloyi, zitsulo zotentha kwambiri, njerwa zotchingira, ulusi wotsekereza, magalasi, zoumba, zotayira zotentha kwambiri zitha kugwiritsidwa ntchito pamalo a aloyi ena.
Kutentha koyenera
Pazipita kutentha kukana ndi 1400 ℃, ndipo kugonjetsedwa ndi kukokoloka mwachindunji ndi malawi kapena mkulu-kutentha mpweya umayenda.
Kutentha kwa kutentha kwa chophimba kumasiyana molingana ndi kukana kutentha kwa magawo osiyanasiyana. Kugonjetsedwa ndi kuzizira ndi kutentha kutentha ndi kugwedezeka kwa kutentha.
Zogulitsa
1. Nano-coatings ndi gawo limodzi, lokonda zachilengedwe, lopanda poizoni, losavuta kugwiritsa ntchito komanso lokhazikika.
2. Chophimbacho ndi chowuma, anti-oxidation, asidi ndi alkali kugonjetsedwa, komanso kugonjetsedwa ndi kutentha kwapamwamba.
3. Zovala za Nano zili ndi mphamvu zabwino zolowera. Kupyolera mu kulowa, kuphimba, kudzaza, kusindikiza ndi kupanga mafilimu, pamapeto pake amakwanitsa kusindikiza kokhazikika katatu ndi anti-oxidation.
4. Ili ndi mawonekedwe abwino opanga mafilimu ndipo imatha kupanga filimu yowuma.
5. Chophimbacho chimagonjetsedwa ndi kuzizira kwambiri ndi kutentha kwa kutentha, kumakhala ndi kutentha kwabwino kwa kutentha kwa kutentha, ndipo kuyesedwa kozizira kwa madzi nthawi zoposa 20 (kusagwirizana ndi kuzizira ndi kusinthanitsa kutentha, chophimbacho sichimang'ambika kapena kuchotsa).
6. Kumamatira kwa zokutira kumaposa 5 MPa.
7. Mitundu ina kapena katundu wina akhoza kusinthidwa malinga ndi zofuna za makasitomala.
Minda yofunsira
1. Metal pamwamba, galasi pamwamba, ceramic pamwamba;
2. Kusindikiza pamwamba pa graphite ndi anti-oxidation, kutentha kwapamwamba pamwamba kusindikiza pamwamba ndi anti-corrosion;
3. Zojambula za graphite, zigawo za graphite;
4. Zigawo za boiler, zosinthira kutentha, ma radiator;
5. Zida za ng'anjo yamagetsi ndi zida zamagetsi.
Njira yogwiritsira ntchito
1. Kukonzekera utoto: Pambuyo pogwedeza kapena kugwedeza bwino, ikhoza kugwiritsidwa ntchito mutasefedwa kudzera pazithunzi za 300-mesh. Kuyeretsa kwazinthu zoyambira: Pambuyo pochotsa mafuta ndikuchotsa mafuta, tikulimbikitsidwa kuchita sandblasting kuti muwonjezere mphamvu. Zotsatira zabwino kwambiri za sandblasting zimatheka ndi 46-mesh corundum (white corundum), ndipo imafunika kuti ifike ku kalasi ya Sa2.5 kapena pamwamba. Zida zokutira: Gwiritsani ntchito zida zokutira zoyera ndi zowuma kuti muwonetsetse kuti palibe madzi kapena zonyansa zina zomwe zimamatira, kuti zisakhudze mawonekedwe opaka kapena kuyambitsa zinthu zolakwika.
2. Njira yokutira: Kupopera mbewu mankhwalawa: Utsi pa kutentha firiji. Ndi bwino kulamulira makulidwe kupopera mbewu mankhwalawa mkati 50 kwa 100 microns. Musanayambe kupopera mbewu mankhwalawa, workpiece pambuyo sandblasting ayenera kutsukidwa ndi anhydrous Mowa ndi zouma ndi wothinikizidwa mpweya. Ngati sagging kapena shrinkage kumachitika, workpiece akhoza preheated mpaka pafupifupi 40 ℃ pamaso kupopera mbewu mankhwalawa.
3. Zida zokutira: Gwiritsani ntchito mfuti yopopera yokhala ndi mainchesi a 1.0. Mfuti yopopera yaying'ono yokhala ndi m'mimba mwake imakhala ndi zotsatira zabwino za atomization komanso zotsatira zopopera bwino. Ma air compressor ndi fyuluta ya mpweya ayenera kukhala ndi zida.
4. Kuthira kuchiritsa: Kupopera mbewu mankhwalawa kukamalizidwa, lolani chogwiriracho chiwume mwachilengedwe kwa mphindi 30, kenaka chiyikeni mu uvuni ndikuchisunga pa madigiri 280 kwa mphindi 30. Pambuyo kuzirala, ikhoza kuchotsedwa kuti igwiritsidwe ntchito.
Wapadera kwa Youcai
1. Kukhazikika kwaukadaulo
Pambuyo poyesa mozama, njira yaukadaulo yaukadaulo ya nanocomposite ceramic yamlengalenga imakhalabe yokhazikika pansi pamikhalidwe yovuta kwambiri, yosagwirizana ndi kutentha kwambiri, kugwedezeka kwamafuta ndi dzimbiri lamankhwala.
2. Ukadaulo wobalalika wa Nano
Wapadera kubalalitsidwa ndondomeko amaonetsetsa kuti nanoparticles ndi wogawana anagawira ❖ kuyanika, kupewa agglomeration. Kuchita bwino kwa mawonekedwe kumawonjezera kugwirizana pakati pa tinthu tating'onoting'ono, kumapangitsanso mphamvu yolumikizana pakati pa zokutira ndi gawo lapansi komanso magwiridwe antchito onse.
3. Kuwongolera kwa zophimba
Mapangidwe olondola ndi njira zophatikizira zimapangitsa kuti ntchito yophimba ikhale yosinthika, monga kuuma, kukana kuvala ndi kukhazikika kwa kutentha, kukwaniritsa zofunikira za ntchito zosiyanasiyana.
4. Mawonekedwe a Micro-nano:
Nanocomposite ceramic particles kukulunga tinthu tating'onoting'ono tating'onoting'ono, kudzaza mipata, kupanga zokutira wandiweyani, ndikuwonjezera kulimba komanso kukana dzimbiri. Nthawiyi, nanoparticles kudutsa pamwamba pa gawo lapansi, kupanga zitsulo-ceramic interphase, amene timapitiriza kugwirizana mphamvu ndi mphamvu wonse.
Mfundo yofufuza ndi chitukuko
1. Nkhani yofananira ndi matenthedwe: Ma coefficients owonjezera azitsulo azitsulo ndi zida za ceramic nthawi zambiri amasiyana pakuwotcha ndi kuzizira. Izi zingayambitse kupanga ma microcracks mu zokutira panthawi ya kutentha kwa njinga, kapena kupukuta. Kuti athane ndi vutoli, Youcai wapanga zida zatsopano zokutira zomwe gawo la kufalikira kwamafuta liri pafupi ndi gawo lapansi lachitsulo, potero kuchepetsa kupsinjika kwamafuta.
2. Kukaniza kugwedezeka kwa kutentha ndi kugwedezeka kwa kutentha: Pamene zitsulo zachitsulo pamwamba zimasintha mofulumira pakati pa kutentha kwakukulu ndi kutsika, ziyenera kupirira kupsinjika kwa kutentha komwe kumabwera popanda kuwonongeka. Izi zimafuna zokutira kuti zikhale ndi kukana kwamphamvu kwa kutentha kwa kutentha. Mwa kukhathamiritsa microstructure ya zokutira, monga kuonjezera kuchuluka kwa magawo olumikizirana ndi kuchepetsa kukula kwa tirigu, Youcai imatha kukulitsa kukana kwake kwamafuta.
3. Mphamvu zomangirira: Mphamvu yolumikizirana pakati pa zokutira ndi gawo lapansi lachitsulo ndizofunikira kuti pakhale bata komanso kulimba kwa zokutira. Kuti muwonjezere mphamvu yomangirira, Youcai amayambitsa wosanjikiza wapakati kapena wosanjikiza pakati pa zokutira ndi gawo lapansi kuti apititse patsogolo kunyowa komanso kulumikizana kwamankhwala pakati pa ziwirizi.
