1.Characters wa CA anapanga njira Sol-gel osakaniza

CA, umatulutsa njira Sol-gel osakaniza, ndi mtundu wa mbewu sintered abrasive. Choncho, dzina lake monga SG abrasive tirigu. The gawo galasi ndi laling'ono kwambiri, zomwe ndi 100-500nm okha, ndipo si chimodzi peresenti wamba corundum kukula galasi. Chidutswa 46 # tirigu lili mabiliyoni particles krustalo. Pamene akupera, mbewu ya chikhalidwe aluminiyamu magetsi zinaphatikizidwa kukhala athyathyathya ndipo deactive, ndi mosavuta kuchokera zida abrasive pansi pa mphamvu akupera. utumiki moyo wake ndi lalifupi. Komabe, CA, mwachitsanzo SG abrasive mbewu, lonse atavala ndondomeko ndi njira zake kudziletsa kukulitsa. Pa moyo wake utumiki watsopano lakuthwa akupera m'mphepete poyera nthawi zonse pamene passivating mbewu zabwino galasi kubwera kuchokera zida akupera pansi pa mphamvu akupera, zomwe zimachititsa mbewu zonse mu udindo lakuthwa. Choncho, zipangizo abrasive yotentha ndi CA ndi moyo wautali gulu, zabwino kudziletsa kukulitsa luso, mkulu kudula dzuwa, komanso osapsa workpieces.

Chifukwa microstructure yake yosiyanasiyana, CA zikusonyeza kusiyana pa abrasive mbewu wovulala khalidwe. CA limasonyeza pamodzi ndi galasi wovulala kuwonongeka, pamene chikhalidwe magetsi zinaphatikizidwa aluminiyamu limasonyeza transgranular wovulala kuwonongeka. Choncho, kulimba kwa CA ndi kawiri kuposa kwa zinaphatikizidwa aluminiyamu wamba.

CA umatulutsa njira Sol-gel osakaniza ali ofanana mipweya ndi kuuma kwa WFA (White zinaphatikizidwa aluminiyamu). Chifukwa yunifolomu ting'onoting'ono microcrystalline matabwa ake, kulimba mkulu ndi ting'onoting'ono wosweka ntchito, CA akhoza ankagwiritsa ntchito akupera zipangizo zovuta ndi ndondomeko ngati chida zitsulo, lolimba zosapanga dzimbiri, kutentha zosagwira aloyi zitsulo, etc.

 2.Features zipangizo abrasive yotentha ndi CA

(1)  The mbewu yakuthwa kwambiri, zomwe zimachititsa kuti ali amphamvu kudula mphamvu, mkulu umapezeka dzuwa. Thiabendazole angagwiritsidwe ntchito yaikulu kwambiri kudula, chakudya wosemera, ntchito katundu ndi mkulu Mwachangu umapezeka. Malinga ndi zimenezo, umodzi ndondomeko kudya angafikire 0.3mm kapena zambiri, zitsulo kuchotsa mtengo kuposa kawiri mawilo wamba corundum umapezeka.

(2) Good kulimba, ang'ono kumva kuwawa, ndipo mawilo akupera ndi mawonekedwe posungira wabwino. Pakuti mwatsatanetsatane umapezeka ndi mawonekedwe akupera, apamwamba ooneka enieni molondola ndi kukula mawonekedwe kugwirizana mosavuta nazo.

(3) Mkulu durability ndi moyo wautali utumiki. Chimakhudza 5 to10 nthawi mawilo wamba corundum umapezeka. Low m'malo pafupipafupi kungachepetse wothandiza processing nthawi ndi downtime, zomwe zimachititsa kuti abwino kugwiritsa ntchito makina n'zosangalatsa kumva ulamuliro basi, pozindikira kupanga basi.

(4) Good kudziletsa kukulitsa ntchito, osati clogging. Zimakhala odekha umapezeka ntchito, kuchepetsa kukonzedwa (okha 1/3 mawilo wamba corundum umapezeka) ndi kusintha kupanga dzuwa.

(5) Mu ntchito akupera, CA akupera magudumu kuposa mawilo wamba corundum umapezeka. Pakuti mtengo, CA kwambiri m'munsi kuposa CBN ndi diamondi abrasives, pamene kuuma wake ndi wofanana ndi wa wamba zinaphatikizidwa aluminiyamu, zomwe zimachititsa kuti sayenera equipments umapezeka wapadera ndi zipangizo kukonza. Choncho alibe amafuna wapadera equipments akupera ndipo palibe mavuto yokonza poyerekeza CBN ndi diamondi abrasives. Lilinso palibe amafuna wapadera kwa akupera madzimadzi. Choncho, n'zosavuta kufalitsa ntchito.
