Kukula kwa kupukuta kophatikizika Kwambiri
Chifukwa chochepa pakupera kupukuta kopitilira muyeso, kafukufuku wa mankhwala osokoneza bongo wapangidwa.
Kupera kokhazikika ndi njira yomwe abrasive omwazikana imagwirizanitsidwa ndi zomatira ndikupanga chida china chapadera cha kupopera pa chopukusira. Kupera kosasunthika kukhoza kupititsa patsogolo kupukuta bwino, akatswiri ambiri kunyumba ndi kunja amakhala ndi chidwi chachikulu ndi njira yopopera yopopera, ndipo anachita kafukufuku wambiri.
Pakadali pano, pali zovuta zina pakuvala kwa zida zopangira okhazikika. Pofuna kupewa kutopetsa kwambiri komanso kutaya zinyalala, nthawi yogwira ntchito komanso kuchuluka kwa ogwira ntchito akuwonjezeka, ndipo mtengo wopangira ukuwonjezeka. Chifukwa chake, ndikofunikira kupititsa patsogolo ndikukonza njira yoyenera yopopera.
Pokonzekera maphatikizidwe abrasiveAt omwe alipo, maiko akunja, monga United States ndi Japan, apanga mtundu watsopano wamapulogalamu olowanirana ophatikizika, omwe amapanga njira yolondola yolumikizira matepi oonda, ndikupangitsa kupukuta kwa zinthu zopangidwa kukonzedwa molondola ndipo zogwirizana.Zinthu zinayi zazikuluzikulu zomwe zimapangidwa mufilimu yoyipa:
1 base nyenzo:
Filimu ya Polyester 857 (PET), yokhala ndi mphamvu yayitali komanso yopingasa yayitali, kukulitsa yaying'ono, yolimba komanso yolimba, komanso makulidwe ofananaEE ndi okhazikika. Makulidwe oyenera a zinthu zapansi ndi: 25, 50, 75 μ M. Pokhala ndi chofunikira cha makina, kukonzekera ndi kupukusa magwiridwe antchito a disin diamondi yopera popangira galasi pokonzanso chiwonetsero chofunikira ndi filimu ya 14Thin, filimu yayikulu siyoyenera, kotero pali mndandanda wa 7, 10, 12, 23, 27, 30, 37 μ M.
2 abrasive:
Japan imagwiritsa ntchito kwambiri Al 2O 3, SiC ndi abrasives zina, komanso Cr 2O 3 (mutu wopera), CeO2, monocrystal ndi polycrystal kupanga daimani, FeO, etc. Iyenera kukhala ndi tinthu tating'ono komanso kufalikira kwa tinthu tating'ono , komwe kumafunikira kuwongolera mwamphamvu kuwongolera kwa tinthu tating'onoting'ono, popanda ma tinthu tambiri. 3M, USAT Pali mitundu inayi ya tinthu tosokoneza tomwe timatulutsa pogaya molondola: Al2O3, SiC, bokosi lochita kupanga corundum ndi CBN. Tinthu tating'onoting'ono tonse timayang'aniridwa bwino ndikugwiritsa ntchito Itha kugwiritsidwa ntchito kupukuta kapena konyowa.
3 binder:
Makamaka utomoni wa ma polima ndi zina zambiri zowonjezera. Ethyl amino mawonekedwe. Zoyambayo ziwiri zimakhala zovuta atachiritsa, ndipo zomalizirazo zimakhala zofewa. Nthawi zambiri, amafunika kuyika kanema kawiri, nthawi yoyamba ndikuwonjezera kudziphatikiza kwa filimuyo.
4 zokutira:
Njira ya Electrostatic ndi njira yokulungira yamagwiritsidwe ntchito zimagwiritsidwa ntchito makamaka. Batani mu njira ya electrostatic. Zoyambira ndi filimu ya polyester. Njira zowola ndi A12O3 、 SiC。 Njira zokutira zimagwiritsidwa ntchito ndi tekinoloji yosindikiza, makina osokosera komanso osakanikirana, kuwongolera makulidwe kumayendetsedwa ndi odzigudubuza, ndiko kusintha kusiyana pakati pa odzigudubuza. Kuphatikiza apo, pali njira zosakanikirana, njira zowonongera, njira ya electroplating ndi Ni plating njira Law, etc. Ku Japan, malire apamwamba a kutentha osagwirizana ndi kutentha kwa filimuyo ndi kutentha kwa zinthu za polymer, pafupifupi 250 ℃. Nthawi zambiri kupera kwa Wet kumatengera, ndipo ozizira ndi madzi ndi mafuta. Nthawi zambiri, madzi amatha kukwaniritsa zofunikira (monga madzi apampopi). Mafuta oyera amagwiritsidwa ntchito kupangira makina mwachindunji, ndipo mafuta a nyali amagwiritsidwa ntchito popukuta aluminiyamu.
Kupera mwanzeru pogwiritsa ntchito filimu yoyipa ndikwotsogola kuposa zida zamalamba zowonjezera. Itha kupititsa patsogolo kuchuluka kwa ntchito ndikupanga, kuchuluka koyenera, mtundu wabwino, kukulitsa mawonekedwe, ndikuwongolera molondola njira yonse yopera.
