Isayensi Yezinto Ezibonakalayo
Amaphedi okupholisha amatshe
Kunezinhlobo ezimbili zamatshe okupholisha: ibhlogo lokupholisha i-resin; idiski lokupholisha i-resin.
Ukupholisha imikhiqizo: beka itshe lokupholisha emikhiqizweni ecutshunguliwe, bese usebenzisa imishini yokusebenza ukuze isebenze ngokushesha futhi “yomise ukupholisha kanye nokupholisha okumanzi” ukuze kufezwe umphumela wokupholisha. Ubuso bomkhiqizo buzoba nokukhanya okukhanyayo okunamandla, okuvame ukubizwa ngokuthi ukucwebezela.
Isimiso
Isimiso sokupholisha sibonakala kakhulu ezicini ezimbili: isimiso sokugaya izinhlayiya; Izimiso zomzimba nezamakhemikhali.
1. Ukugaya izinhlayiya: lapho izinhlayiya ezihuquzelayo zisuka ekugayeni okungaqinile kuya ekugayeni okungaqinile nokupholisha, umkhondo wokugaya we-abrasive ebusweni betshe usuka ekubeni oqinile uye kocolekileyo bese kungabikho mkhondo obonakalayo. Umphezulu uzoba bushelelezi, uyisicaba futhi uthambile. Lapho ukujula kufinyelela kuma-micron angu-110, umphezulu ocutshunguliwe uzobonakala ukhanya kakhulu, ukhanya futhi ukhanya.
Ukugaya izinhlayiya kuqukethe izinqubo ezilandelayo:
① Ukugaya okuqinile: kuyadingeka ukuthi ithuluzi lokugaya libe nomkhawulo wokusika ojulile, ukusebenza kahle kokugaya okuphezulu, okusanhlamvu kokugaya okuqinile kanye nobuso bokugaya obuqinile. Ngokuyinhloko ukususa iminonjana ye-saw blade eshiywe enkambisweni yangaphambilini bese ugaya ubuso obuthambile kanye nobomodeli bomkhiqizo endaweni yawo;
② Ukugaya okuncane: susa amamaki okugaya aqinile ukuze wakhe uhlamvu olusha oluhle, bese indawo yokucubungula umkhiqizo ibushelelezi futhi ibushelelezi;
③ Ukugaya kahle: iphethini, okusanhlamvu nombala womkhiqizo ngemva kokugaya kahle kuboniswe ngokucacile, ubuso bubushelele futhi buthambile, futhi kukhona ukukhanya okubuthakathaka;
④ Ukugaya kahle: umkhiqizo ocutshunguliwe awunawo umkhondo obonakalayo. Ubuso bubushelelezi kakhulu, futhi ukukhanya kungafinyelela kuma-degrees angu-40 ~ 50;
⑤ Ukupholisha: ubuso bukhanya njengesibuko, bunokukhanya okuthile okucacile (ngaphezu kwama-degree angu-85).
2. Isimiso se-physicochemical:Kunezinqubo ezimbili zokupholisha, okungukuthi “ukupholisha okomile kanye nokupholisha okumanzi”. Lapho imikhiqizo yamatshe inemiphumela ebonakalayo kanye neyamakhemikhali phakathi “komile nokumanzi”, ukupholisha okomile kuwukuhwamukisa amanzi lapho izinga lokushisa lobuso betshe likhuphuka, okuholela ekwandeni kokuhlushwa kwetshe lokupholisha, ukuze kufezwe umphumela wokuqinisa. Ukucwebezela komkhiqizo kuqala ukuhlangabezana nezidingo ezifanele, futhi ukucwebezela kufinyelela ngaphezu kwama-degrees angu-85 noma ngaphezulu.
Itshe lokupholisha lipholisha emikhiqizweni ecutshunguliwe. Ngemva kokuba imikhiqizo epholisha isishile, engeza amanzi ebusweni bepuleti ukuze unciphise izinga lokushisa. Akuvunyelwe ukwengeza amanzi njalo noma ukwengeza inani elikhulu lamanzi. Ngaphandle kwalokho, umphumela wokugcoba wamanzi uzokwenza ukuthi ukupholisha kungafinyeleli emphumeleni ofanele, futhi ukupholisha okomile akukwazi ukusetshenziswa. Izinga lokushisa elidlulele lizoshisa ubuso bepuleti futhi libangele imifantu ebusweni bepuleti.
Ngokuvamile, ngemva kokugaya kahle, ukukhanya kwemikhiqizo kungaba ngu-40 ~ 50. Kodwa-ke, ezinye izinto zamatshe azikwazi ukufinyelela ukukhanya okungenhla ngemva kokugaya kahle, njengesihlabathi esimnyama seShanxi, isihlabathi segolide esimnyama, uJining omnyama, njll. ukukhanya kwemikhiqizo enjalo ngemva kokugaya kahle kungama-degrees angu-20 ~ 30 kuphela. Akwanele ukuqonda incazelo yokuqala yokugaya ngezinhlayiya zangaphambili. Lolu hlobo lwemikhiqizo luzoqinisa inqubo yokupholisha futhi lukhiqize ukusabela ngokomzimba namakhemikhali lapho ukupholisha “komile futhi kumanzi” futhi izinga lokushisa likhuphuka futhi lehla, Ngemva “kokupholisha okomile nokupholisha okumanzi”, ukukhanya komkhiqizo kuyathuthuka kancane kancane, futhi ukukhanya kufinyelela ngaphezu kwama-degrees angu-85.
Umshini wokupholisha amatshe ochwepheshe onemishini emithathu yokupholisha amatshe
Izici eziningana ezithinta ukupholishwa kwamatshe: umphumela wokupholishwa kwamatshe uncike ezicini ezimbili: esinye ubuchwepheshe bokupholishwa obamukelwe, okungukuthi izici zangaphandle "ezitholiwe" zokwenziwa; Okwesibili, kunezizathu zangaphakathi "zemvelo" zetshe ngokwalo.
Uma izici zangaphakathi zetshe zingacatshangelwa, izici eziyinhloko ezithinta ukupholishwa kwetshe uhlobo lwe-ejenti yokupholisha, uketshezi lokupholisha (unamathisela), amathuluzi okugaya okupholisha,amaphedi okusantisa idayimane(amathuluzi, amabhlogo okugaya) kanye nemingcele yenqubo yokupholisha.
(1) Uhlobo lwe-ejenti yokupholisha
Nakuba i-ejenti yokupholisha iyinto ekhethekile yokupholisha, umehluko phakathi kwayo nezinto zokugaya ubonakala kakhulu endleleni yokucubungula. Empeleni, ezinye izinto ze-micro powder ezinobulukhuni obuphansi zingasetshenziswa njengezinto zokupholisha. Kodwa ngokuvamile, i-ejenti yokupholisha enobulukhuni obuphezulu ingcono kuneyobulukhuni obuphansi futhi inobubanzi bokusetshenziswa. I-diamond polishing powder ingafinyelela umphumela wokupholisha owanelisayo ezintweni eziningi zamatshe.
(2) Uketshezi lokupholisha (unamathisela)
Amanzi awuketshezi lokupholisha olusetshenziswa kakhulu. Alukwazi nje ukudlala indima yokupholisa ngokugaya, kodwa futhi lusebenza njengendlela yokwelapha imiphumela yomzimba neyamakhemikhali enkambisweni yokupholisha.
Uma ukupholishwa kwamatshe kusekelwe kakhulu ekugayweni komshini, njengempuphu yedayimane, uketshezi lokupholishwa ngokuvamile luwuketshezi oluphilayo olusekelwe kumafutha, njengamafutha omshini wokuthunga. Imiphumela yalo yokupholisa, ukugcoba kanye nokuhlakazeka inhle kakhulu.
I-paste yokugaya idayimane, kokubili amanzi namafutha, futhi ingafakwa nezidayisi zombala. Ifomula yile: i-abrasive + i-dispersant + i-carrier + amanzi + i-colorant.
(3) Idiski yokupholisha (ithuluzi, ibhlogo lokugaya)
Iphaneli yokukhanya yetshe eliyisicaba iyindlela yokuveza nokucubungula ukugaya ubuso betshe. Amadiski aqinile enziwe ngezinto zensimbi avame ukusetshenziswa njengamadiski okupholisha. Ubuso bokupholisha be-floppy disk polishing kulula ukubufaka endaweni egobile lapho itshe licindezelwa, okufanelekela ukupholisha ubuso be-arc. Idiski eliqinile eliphakathi linokumelana okuhle nokuguguleka okuhle, futhi linokuguquguquka okuthile. Liphinde libe nomphumela omuhle wokupholisha etsheni eliyisicaba.
(4) Amapharamitha enqubo yokupholisha
Amapharamitha enqubo afaka ukuhlushwa kanye nokuhlinzekwa kwe-ejenti yokupholisha, ingcindezi kanye nesivinini esiqondile ngesikhathi sokupholisha. Ngaphambi kokuba ukuhlushwa kube ngaphansi kwenani elithile, isivinini sokupholisha siyanda ngokwanda kokuhlushwa kwe-ejenti yokupholisha. Ngemva kokuba ukuhlushwa kufinyelele esiphezulu, uma ukuhlushwa kuphinde kwanda, ijubane lokupholisha liyancipha. Ngokufanayo, lapho inani lokuphakelwa kwe-ejenti yokupholisha lisenani elithile, ijubane lokupholisha liphezulu, futhi uma inani lokuphakelwa liqhubeka landa, ijubane lokupholisha liyancipha. Ukwandisa ingcindezi kahle ngesikhathi sokupholisha kungandisa ijubane lokupholisha, kodwa ingcindezi enkulu kakhulu izoqinisa umphumela wokugaya, ongelusizo ekwakhekeni kobuso obukhazimulayo. Ijubane lokupholisha lincike esivinini esijikelezayo sediski yokupholisha (ithuluzi), kodwa uma ijubane eliqondile liphezulu kakhulu, i-ejenti yokupholisha izophonswa ngaphandle, okubangela imfucuza.
(5) Ikhwalithi yenqubo yangaphambilini kanye nokuqina kobuso betshe.
Uma sicabangela izici zangaphakathi zetshe ngokwalo, njengokwakheka kwamaminerali kwezinto zamatshe, kubonakala kakhulu ezicini zenqubo yokupholisha amatshe.
① Izici zenqubo yokupholisha amatshe anezakhi ezahlukene zamaminerali zihlukile. Isibonelo, izinto zamatshe ezakhiwe kakhulu ngamaminerali e-serpentine, njengemabula eluhlaza ye-Dahua, zingezezinto zamatshe ezinokuqina okuqinile, ezingapholisha kodwa akulula ukuzipholisha.
② Imabula iqukethe inani elithile lamaminerali enhlabathi, okuzothinta nokukhanya kwetshe. Isibonelo esijwayelekile yi-red Anhui snail e-Anhui. Igama ledwala liyi-layer selecting stone biological limestone. Ipuleti elisikiwe endaweni efanayo linephethini yemvelo efana nembali, efana ne-clam snail, futhi lihle kakhulu. Kodwa-ke, ngoba i-ore iqukethe inani elithile lezingxenye zamaminerali zobumba, kunzima ngepuleti elipholishiwe ukuthola ukukhanya okungaphezu kwama-85.
③ I-granite ekhululekile ivame ukuguguleka ngezinga elithile ngamaminerali aseMuscovite (ubumba noma i-hydromica), futhi umphumela wayo wokupholisha kunzima ukufinyelela ezingeni lokupholisha le-granite entsha. Lokhu kufanele kube yikhwalithi yetshe.
④ Ngokwethiyori, amaminerali ahlukene kufanele asebenzise ama-ejenti okupholisha ahlukene. Ukupholisha uhlobo lobuchwepheshe bokucubungula amatshe kahle, futhi abanye abantu bakubiza ngokuthi ubuchwepheshe bokupholisha ubuso. Kunezici eziningi ezithinta ukupholisha kwezinto zamatshe, okuhlanganisa izinkinga zezimo zenqubo kanye nemingcele enkambisweni yokupholisha, izinhlobo zama-ejenti okupholisha, izinto ezisizayo nama-disc okupholisha (amathuluzi namabhulokhi), kanye nokwakheka kwamaminerali kanye nekhwalithi yezinto zamatshe.
