Ama-polish pad adlala indima ebalulekile njengethuluzi lokugaya ngokunemba emikhakheni yesayensi yezinto zokwakha kanye nobunjiniyela bomphezulu. Umsebenzi wawo ukupholisha umphezulu wezinto zokwakha ngezindlela zomzimba noma zamakhemikhali ukuze kufezwe ukuqeda okufiselekayo kanye nezakhiwo zomphezulu. Kuye ngezidingo zohlelo lokusebenza, ama-polish disc atholakala ezintweni ezahlukahlukene, njengedayimane, i-alumina, i-silicon carbide, njll., ngayinye enezici zayo zokugaya ezihlukile kanye nobubanzi bokusetshenziswa.
Emkhakheni wokukhiqiza ama-semiconductor, ama-wafer acwebezelayo abaluleke kakhulu, ikakhulukazi enkambisweni yokupholisha ngomshini wamakhemikhali (i-CMP), esetshenziselwa ukufeza ukuthambekela okuphezulu kobuso be-wafer. Ubuchwepheshe be-CMP buhlanganisa ukugaya ngomshini kanye nokuqopha ngamakhemikhali, kuxazululwe ngempumelelo ukungalingani kwe-micro-geometry ye-wafer, ngaleyo ndlela kuqinisekiswe ukusebenza nokuthembeka kwezingxenye ze-microelectronic.
Emkhakheni wokucubungula insimbi, ama-polishing pad asetshenziselwa ukususa izingqimba ezingcolisiwe kanye nokungcola ebusweni bezinto zokusebenza kanye nokuthuthukisa ukuqeda ubuso, ngaleyo ndlela kuthuthukiswe ukubukeka nokusebenza kwezinto. Isibonelo, ezimbonini zezindiza nezimoto, lapho ukwelashwa kwendawo yezingxenye kudinga kakhulu, ukupolisha kungathuthukisa kakhulu ukumelana nokugqwala kanye nokuphila kokukhathala kwemikhiqizo.
Ngezinto zokwakha ezahlukene kanye nezidingo zokucubungula, amapharamitha anjengosayizi wezinhlamvu, ubulukhuni kanye nesimo sediski yokupholisha kudingeka aklanywe ngokucophelela. Ukukhetha usayizi wezinhlamvu kuthinta ngqo ubulukhuni bomphezulu, kuyilapho ubulukhuni bunquma izinga lokususwa kwenqubo yokupholisha kanye nokuqina kwethuluzi. Ngaphezu kwalokho, ingcindezi, isivinini kanye nezimo zemvelo zenqubo yokupholisha kudingeka zilawulwe ngokuqinile ukuqinisekisa ukuthi ikhwalithi yomphezulu oyifunayo iyafinyelelwa.
Inkampani iChemshun Ceramics ingumkhiqizi ochwepheshe wezinto zobumba zezimboni,Amadiski Okupholisha Amafutha E-Alumina angu-99.7%ingatholakala. Siyakwamukela ukuzobuza.
