Njira yopukutira nkhungu ya pulasitiki

Kupukuta makina

Kupukuta kwa makina ndi njira yopukuta yomwe imadalira kudula ndi kusintha kwa pulasitiki pamwamba pa chinthucho kuti achotse zigawo zopindika zopukutidwa kuti pakhale malo osalala. Kawirikawiri, timitengo ta miyala yamafuta, mawilo a ubweya, sandpaper, ndi zina zotero zimagwiritsidwa ntchito, ndipo ntchito zamanja ndiye njira yayikulu. Zigawo zapadera monga pamwamba pa thupi lozungulira zingagwiritsidwe ntchito. Pogwiritsa ntchito zida zothandizira monga ma turntable, kupukuta kolondola kwambiri kungagwiritsidwe ntchito kwa iwo omwe ali ndi zofunikira zapamwamba pamwamba. Kupukuta kolondola kwambiri ndi kugwiritsa ntchito zida zapadera zokwawa, zomwe zimakanikizidwa mwamphamvu pamwamba pa chinthu chogwiritsidwa ntchito mumadzimadzi opukuta okhala ndi zokwawa kuti azizungulira mwachangu. Pogwiritsa ntchito ukadaulo uwu, kukhwima kwa pamwamba kwa Ra0.008μm kumatha kuchitika, komwe ndi njira yapamwamba kwambiri pakati pa njira zosiyanasiyana zopukuta. Ma mold a lens optical nthawi zambiri amagwiritsa ntchito njira iyi.

Kupukuta mankhwala

Kupukuta mankhwala ndikopangitsa kuti pamwamba pakhale gawo looneka ngati pulasitiki lozungulira kwambiri la zinthu zomwe zili mu chipangizo cha mankhwala lisungunuke bwino kuposa pamwamba pa chopingasa, kuti pakhale malo osalala. Ubwino waukulu wa njira iyi ndikuti sifunikira zida zovuta, imatha kupukuta zinthu zogwirira ntchito zokhala ndi mawonekedwe ovuta, komanso imatha kupukuta zinthu zambiri nthawi imodzi, ndi luso lapamwamba. Vuto lalikulu la kupukuta mankhwala ndi kukonzekera madzi opukuta. Kuuma kwa pamwamba komwe kumapezeka popukuta mankhwala nthawi zambiri kumakhala 10 μm.

Kupukuta kwa electrolytic

Mfundo yaikulu ya kupukuta kwa electrolytic ndi yofanana ndi ya kupukuta kwa mankhwala, kutanthauza kuti, mwa kusungunula pang'ono pang'ono pamwamba pa chinthucho kuti pamwamba pake pakhale posalala. Poyerekeza ndi kupukuta kwa mankhwala, zotsatira za cathode reaction zimatha kuchotsedwa, ndipo zotsatira zake zimakhala bwino. Njira yopukuta ya electrochemical imagawidwa m'magawo awiri: (1) Kulinganiza kwa macroscopic Zinthu zosungunuka zimafalikira mu electrolyte, ndipo kukhwima kwa geometric kwa pamwamba pa chinthucho kumachepa, Ra>1μm. ⑵ Kulinganiza kotsika: Kugawa kwa anode, kuwala kwa pamwamba kumawonjezeka, Ra<1μm.

Kupukuta kwa akupanga

Ikani workpiece mu abrasive suspension ndikuyiyika pamodzi mu ultrasonic field, kutengera mphamvu ya oscillation ya ultrasonic, kuti abrasive ipukutidwe ndikupukutidwa pamwamba pa workpiece. Ultrasonic machining ili ndi mphamvu yaying'ono ya macroscopic ndipo sidzayambitsa kusintha kwa workpiece, koma n'zovuta kupanga ndikuyika zida. Ultrasonic processing ikhoza kuphatikizidwa ndi njira zamakemikolo kapena zamagetsi. Pamaziko a solution corrosion ndi electrolysis, ultrasonic vibration imagwiritsidwa ntchito kusakaniza yankho, kotero kuti zinthu zosungunuka pamwamba pa workpiece zilekanitsidwe, ndipo dzimbiri kapena electrolyte pafupi ndi pamwamba zimakhala zofanana; cavitation effect ya ultrasonic mumadzimadzi imathanso kuletsa njira ya dzimbiri ndikuthandizira kuwala kwa pamwamba.

Kupukuta madzimadzi

Kupukuta madzi kumadalira madzi othamanga kwambiri komanso tinthu tomwe timanyamula kuti titsuke pamwamba pa chinthu chogwirira ntchito kuti tikwaniritse cholinga chopukuta. Njira zomwe zimagwiritsidwa ntchito kwambiri ndi izi: kukonza ndege yopapatiza, kukonza ndege yamadzimadzi, kupukuta kwa hydrodynamic ndi zina zotero. Kupukuta kwa hydrodynamic kumayendetsedwa ndi kupanikizika kwa hydraulic kuti madzi onyamula tinthu topapatiza aziyenda mozungulira pamwamba pa chinthu chogwirira ntchito mothamanga kwambiri. Chinthuchi chimapangidwa makamaka ndi mankhwala apadera (zinthu zofanana ndi polymer) zomwe zimatha kuyenda bwino pansi pa kupsinjika kochepa komanso kusakanizidwa ndi zinthu zopopera. Zinthu zopopera zimatha kupangidwa ndi ufa wa silicon carbide.

Kupera ndi kupukuta maginito

Kupukuta kwa maginito kogwiritsa ntchito maginito kopangira maburashi okhwima pansi pa mphamvu ya maginito kuti agaye ntchito. Njirayi ili ndi magwiridwe antchito apamwamba, khalidwe labwino, kuwongolera kosavuta kwa momwe zinthu zimagwirira ntchito komanso mikhalidwe yabwino yogwirira ntchito. Pogwiritsa ntchito ma abrasives oyenera, kuuma kwa pamwamba kumatha kufika pa Ra0.1μm. 2 Kupukuta kwa makina kutengera njira iyi Kupukuta komwe kwatchulidwa pokonza nkhungu zapulasitiki ndikosiyana kwambiri ndi kupukuta pamwamba komwe kumafunikira m'mafakitale ena. Kunena zoona, kupukuta kwa nkhungu kuyenera kutchedwa kuwongolera pagalasi. Sikuti kumangokhala ndi zofunikira zapamwamba pakupukuta kokha, komanso kumakhala ndi miyezo yapamwamba yoti pamwamba pakhale posalala, kusalala komanso kulondola kwa geometry. Kupukuta pamwamba nthawi zambiri kumafuna malo owala okha. Muyezo wa kukonza pamwamba pagalasi umagawidwa m'magawo anayi: AO=Ra0.008μm, A1=Ra0.016μm, A3=Ra0.032μm, A4=Ra0.063μm. N'zovuta kuwongolera molondola kulondola kwa geometry ya zigawo chifukwa cha njira monga kupukuta kwa electrolytic ndi kupukuta kwamadzimadzi. Komabe, khalidwe la pamwamba pa kupukuta mankhwala, kupukuta kwa ultrasonic, kupukuta kwa magnetic abrasive ndi njira zina sizikugwirizana ndi zofunikira, kotero kukonza pagalasi kwa nkhungu zolondola kumapitirirabe kupukuta kwamakina.
