Indlela yokupolisha isikhunta seplastiki
Ukupholisha ngoomatshini
Ukupholisha ngoomatshini yindlela yokupholisha exhomekeke ekusikeni nasekuguqulweni komphezulu wezinto ukuze kususwe iindawo ezikhazimlayo ezicociweyo ukuze kufunyanwe umphezulu ogudileyo. Ngokubanzi, kusetyenziswa izinti zamatye eoyile, amavili oboya, iphepha lesanti, njl.njl., kwaye imisebenzi yezandla yeyona ndlela iphambili. Iindawo ezikhethekileyo ezifana nomphezulu womzimba ojikelezayo zingasetyenziswa. Ukusebenzisa izixhobo ezincedisayo ezifana nee-turntables, ukupholisha ngobuchule obuphezulu kunokusetyenziswa kwabo baneemfuno zomgangatho ophezulu womphezulu. Ukupholisha ngobuchule obuphezulu kukusetyenziswa kwezixhobo ezikhethekileyo zokuqhobosha, ezicinezelwa ngokuqinileyo kumphezulu ocociweyo wento yokusebenza kulwelo lokupholisha oluqulethe izinto zokuqhobosha ukuze kujikelezwe ngesantya esiphezulu. Ukusebenzisa obu buchwephesha, uburhabaxa bomphezulu beRa0.008μm bunokufezekiswa, obulelona liphezulu phakathi kweendlela ezahlukeneyo zokupholisha. Ii-optical lens molds zihlala zisebenzisa le ndlela.
Ukupholisha ngamakhemikhali
Ukupolisha ngekhemikhali kukwenza umphezulu ongaphezulu ube yinxalenye encinci engqukuva yezinto ezikwindawo yekhemikhali ukuba unyibilike ngakumbi kunenxalenye engqukuva, ukuze ufumane umphezulu ogudileyo. Inzuzo ephambili yale ndlela kukuba ayifuni zixhobo zintsonkothileyo, inokupolisha izinto zokusebenza ezineemilo ezintsonkothileyo, kwaye inokupolisha izinto zokusebenza ezininzi ngaxeshanye, ngokusebenza kakuhle. Ingxaki ephambili yokupolisha ngekhemikhali kukulungiselela ulwelo lokupolisha. Uburhabaxa bomphezulu obufunyenwe ngokupolisha ngekhemikhali ngokubanzi buyi-10 μm.
Ukupholisha nge-electrolytic
Umgaqo osisiseko wokupolisha nge-electrolytic uyafana nowokupolisha ngekhemikhali, oko kukuthi, ngokunyibilikisa ngokukhetha iiprotrusions ezincinci kumphezulu wezinto ukuze kwenziwe umphezulu ube mtyibilizi. Xa kuthelekiswa nokupolisha ngekhemikhali, isiphumo se-cathode reaction sinokususwa, kwaye isiphumo singcono. Inkqubo yokupolisha nge-electrochemical yahlulwe ngamanyathelo amabini: (1) Ukulinganisa i-macroscopic Iimveliso ezinyibilikisiweyo ziyasasazeka kwi-electrolyte, kwaye uburhabaxa bejometri bomphezulu wezinto buyancipha, i-Ra>1μm. ⑵ Ukulinganisa ukukhanya okuphantsi: I-Anode polarization, ukukhanya komphezulu kuyaphucuka, i-Ra<1μm.
Ukupholisha nge-ultrasonic
Faka i-workpiece kwi-abrasive suspension uze uyidibanise kwintsimi ye-ultrasonic, uxhomekeke kwisiphumo sokushukuma kwe-ultrasonic, ukuze i-abrasive icolwe kwaye ipholishwe kumphezulu we-workpiece. I-Ultrasonic machining inamandla amancinci e-macroscopic kwaye ayiyi kubangela ukuguqulwa kwe-workpiece, kodwa kunzima ukuyenza nokufaka izixhobo. Ukucubungula i-Ultrasonic kunokudityaniswa neendlela ze-chemical okanye ze-electrochemical. Ngokusekelwe kwisisombululo sokugqwala kunye ne-electrolysis, i-ultrasonic vibration isetyenziswa ukuxuba isisombululo, ukuze iimveliso ezinyibilikisiweyo kumphezulu we-workpiece zahlulwe, kwaye ukugqwala okanye i-electrolyte kufutshane nomphezulu ifane; isiphumo se-cavitation se-ultrasonic kulwelo sinokuthintela inkqubo yokugqwala kwaye senze kube lula ukukhanya komphezulu.
Ukupolisha ngolwelo
Ukupholisha ngolwelo kuxhomekeke kulwelo oluhamba ngesantya esiphezulu kunye namasuntswana arhabaxa athwalwa yiyo ukuhlamba umphezulu wento yokusebenza ukuze kufezekiswe injongo yokupholisha. Iindlela ezisetyenziswa rhoqo zezi: ukupholisha ngejethi erhabaxa, ukupholisha ngejethi yolwelo, ukupholisha nge-hydrodynamic njalo njalo. Ukupholisha nge-hydrodynamic kuqhutywa luxinzelelo lwe-hydraulic ukwenza ukuba into yolwelo ethwala amasuntswana arhabaxa ihambe isiya phambili nangaphambili kumphezulu wento yokusebenza ngesantya esiphezulu. Le nto yenziwe kakhulu ngeekhompawundi ezikhethekileyo (izinto ezifana ne-polymer) ezinokuhamba kakuhle phantsi koxinzelelo oluphantsi kwaye zixutywe nee-abrasives. Ii-abrasives zingenziwa nge-silicon carbide powder.
Ukugaya nokupolisha ngemagnethi
Ukupholisha ngemagnethi okuqhoboshela kukusebenzisa ii-abrasives eziqhoboshela ukwenza iibhrashi eziqhoboshela phantsi kwesenzo sentsimi yemagnethi ukucola umsebenzi. Le ndlela isebenza kakuhle kakhulu, ikumgangatho ophezulu, ulawulo olulula lweemeko zokucubungula kunye neemeko zokusebenza ezilungileyo. Ukusebenzisa ii-abrasives ezifanelekileyo, uburhabaxa bomphezulu bunokufikelela kwi-Ra0.1μm. 2 Ukupholisha ngoomatshini ngokusekelwe kule ndlela Ukupholisha okukhankanyiweyo ekusetyenzisweni kwee-molds zeplastiki kwahlukile kakhulu ekupholiseni komphezulu okufunekayo kwamanye amashishini. Ngokuthe ngqo, ukupholisha kwe-mold kufanele kuthiwe yi-mirror processing. Ayinazo nje kuphela iimfuno eziphezulu zokupholisha ngokwayo, kodwa ikwanazo nemigangatho ephezulu yokuthamba komphezulu, ukuguda kunye nokuchaneka kwejometri. Ukupholisha komphezulu ngokubanzi kufuna kuphela umphezulu okhanyayo. Umgangatho wokucubungula umphezulu wesibuko wahlulwe ngamanqanaba amane: AO=Ra0.008μm, A1=Ra0.016μm, A3=Ra0.032μm, A4=Ra0.063μm. Kunzima ukulawula ngokuchanekileyo ukuchaneka kwejometri kwamacandelo ngenxa yeendlela ezifana nokupholisha nge-electrolytic kunye nokupholisha ngolwelo. Nangona kunjalo, umgangatho womphezulu wokupholisha ngeekhemikhali, ukupholisha nge-ultrasonic, ukupholisha nge-magnetic abrasive kunye nezinye iindlela azifikeleli kwiimfuno, ngoko ke ukucocwa kwesibuko kweenkuni ezichanekileyo kusekupholisha ngoomatshini.
